Bob says that he can find the area of the triangle below using the formula: A = [tex]\frac{1}{2}[/tex] * 8 *18 * sin (120°). Is he correct? Explain why or why not.
Answer:
No.
Step-by-step explanation:
No, Bob is not correct.
The formula he's using is the following:
[tex]A=\frac{1}{2} ab\sin(C)[/tex]
The important thing here is that the angle is between the two sides.
In the given triangle, 120 is not between 8 and 18. Therefore, using this formula will not be valid.
Either Bob needs to find the other side first or find the angle between 8 and 18.

Joaquin fue al mercado y compro 2,2 kg de papa a S/.1,2 soles el kilo y 3,2 kg de arroz a S/.3,7 soles el kilo, si pagó con un billete de 20, cuanto recibió de vuelto?
Responder:
5,52
Explicación paso a paso:
Dado lo siguiente:
Precio por kilo de papa = 1.2
Kg de papa comprada = 2.2kg
Precio por kilo de arroz = 3.7 por kilo
Kg de arroz comprado = 3.2 kg
Valor del boleto emitido para el pago = 20
Precio total de la papa:
Precio * kg comprado
1.2 * 2.2 = 2.64
Precio total del arroz:
Precio * kg comprado
3.7 * 3.2 = 11.84
Cantidad total gastada = (precio total del arroz + precio total de la papa)
2.64 + 11. 84 = 14.48
Cambio pendiente = 20 - 14.48 = 5.52
-11b+7=4 someone help I’ve been stuck on this problem forever
Answer: Hi!
First, we will use inverse operations to remove the 7. Subtract 7 on both sides:
7 - 7 = 0
4 - 7 = -3
Our equation now looks like this:
-11b = -3
Now we will use inverse operations to isolate the b. Divide -11 on both sides:
-11b ÷ -11 = b
-3 ÷ -11 = 3/11
Our equation now looks like this:
3/11 = b
3/11 is equal to b. This is your answer!

Two trees are leaning on each other in the forest. One tree is 19 feet long and makes a 32° angle with the ground. The second tree is 16 feet long. What is the approximate angle, x, that the second tree makes with the ground? A 0.6° B 35.0° C 39.0° D 58.0°
Answer:
C 39.0
Step-by-step explanation:
To find the approximate angle, x, that the second tree makes with the ground, we can use the concept of similar triangles Therefore the correct option is B.
Let's calculate the height of the first tree using the given information. We can use the formula for the opposite side in a right triangle: opposite = adjacent * tan(angle). Therefore, the height of the first tree is approximately [tex]19 * tan(32°) = 19 * 0.6249 ≈ 11.873[/tex] feet. Now, we can set up a proportion between the two trees based on their heights. Let x be the angle the second tree makes with the ground.
We have the following proportion: (height of first tree)/(height of second tree) = (length of first tree)/(length of second tree). Substituting the known values, we have [tex]11.873/16 = 19/x[/tex]. Cross-multiplying gives us [tex]11.873x = 304,[/tex] and dividing both sides by 11.873 yields[tex]x ≈ 25.63°.[/tex] The approximate angle, x, that the second tree makes with the ground is closest to 35.0°.
Hence the correct option is B

Answer:
A.
Step-by-step explanation:
All of those graphs represent functions. You are able to tell because they all pass the vertical line test. The vertical line test is conducted by drawing a line that goes vertically and intercepts any point of the line in question. If the function crosses the vertical line twice, it is not a function. If it only intercepts once, it is a function. In this case, every graph is a function because they would intercept a vertical line once.

PLEASE help me with this question!!! REALLY URGENT!
Answer:
B
Step-by-step explanation:
So we have a table of values of a used car over time. At year 0, the car is worth $20,000. By the end of year 8, the car is only worth $3400.
We can see that this is exponential decay since each subsequent year the car depreciates by a different value.
To find the rate of change the car depreciates, we simply need to find the value of the exponential decay. To do this (and for the most accurate results) we can use the last term (8, 3400).
First, we already determined that the original value (year 0 value) of the car is 20,000. Therefore, we can say:
[tex]f(t)=20000(r)^t[/tex]
Where t is the time in years and r is the rate (what we're trying to figure out).
Now, to solve for r, use to point (8, 3400). Plug in 8 for t and 3400 for f(t):
[tex]3400=20000(r)^8\\3400/20000=17/100=r^8\\r=\sqrt[8]{17/100}\approx0.8[/tex]
In other words, the rate of change modeled by the function is 0.8.
As expected, this is exponential decay. The 0.8 tells us that the car depreciates by 20% per year.
In which scenarios are surveys appropriate? or when is it appropriate to use experiments?
Answer:
1. Surveys are used to obtain specific information from a group of people. It is administered by politicians, professionals, sociologists, and other groups to obtain data from their subjects of interest.
2. Experiments are used to establish cause-and-effect relationships. Scientists use them for highly-controlled tests to give/withdraw credence to some hypotheses.
Step-by-step explanation:
Surveys, when applied to human subjects, are used to obtain data from a selected sample of subjects. Surveys, which can be applied through mails, telephones, the internet, in-person, and through other means are aimed at getting the opinions, thoughts, and beliefs of the participants. It is administered by politicians, professionals, sociologists, and other groups to obtain data from their subjects of interest. This data can be qualitative or quantitative.
Experiments are administered to provide support or refute a given hypothesis. They establish cause and effect relationships. Scientists use them for highly-controlled tests to give/deny credence to some hypotheses. Positive controls establish the hypothesis as true. They could be conducted in the laboratory, in the field, or through observations.

name four points that are not coplanar
Answer: U, W, Z and Y
Step-by-step explanation:
4 points are not coplanar if there does not exist any plane that contains the 4 points.
So, a plane is formed by a line and one point outside of it.
Then, we want to select the last point in such a way that it lies outside of the plane generated by the first 3 points selected.
For example:
If first we select Point U and Point W, we will have a line, as shown in the image.
Now we can select the Point Z, that is outside the line, and now we have the plane M that you can see in the image.
Now we need to select a point that is not in the plane, the only two options are Point X and Point Y, we can select any of those two, let's take the Point Y.
So, here we have that:
Points U, W, Z and Y are not coplanar.

A shopkeeper allowed 10% discount on his goals
to make 20% profit If he sold a watch for
Rs.10,170 with 13 %. VAT, by what percent
is the discourt to be increased to make only
12% profit
Answer:
To make only 12% profit, the discount should be increased to 16%
Step-by-step explanation:
The given information are;
The percentage discount on goods = 10%
The profit made from the sale of the watch = 20%
The amount the watch was sold = Rs.10,710
The percentage VAT included = 13%
Let the recommended selling price of the watch = X
Therefore, we have;
The price after 10% discount = 0.9×X
Which gives;
The amount the watch was sold = Price after 10% discount + Price after 10% discount ×VAT
The amount the watch was sold = 0.9×X + 0.9×X×13% = 0.9×X + 0.9×X×0.13
Rs.10,710 = 0.9×X + 0.9×X×0.13 = 1.017×X
X = Rs.10,170/1.017 = Rs. 10,000
The recommended selling price of the watch = Rs. 10,000
The profit was 20% of selling price which gives;
Profit = Selling price - Cost price = Rs. 9,000 - Rs. X = 0.2 × Rs. X
9000 - X = 0.2×X
9000 = X + 0.2×X = 1.2×X
X = 9000/1.2 = Rs. 7,500
To make only 12% profit, we have;
12% of Rs. 7,500 = 0.12 × Rs.7,500 = Rs. 900
Selling price = Cost price + Profit = Rs. 7,500 + Rs. 900 = Rs. 8,400
Percentage discount from Rs.10,000 to get Rs. 8,400 is given as follows;
Percentage discount = Y%
Therefore;
Y = (10,000 - 8,400)/10000 × 100 = 0.16 × 100 = 16%
Y = 16%
Therefore, to make only 12% profit, the discount should be increased to 16%.

Answer:
The regular bottle holds 9 fl oz less
Step-by-step explanation:
Given
Family Size = 12 fl oz
Required
Determine the size held less by the regular bottle
From the question, we have that the regular bottle holds 75% less;
[tex]Regular\ Size = 75\% * Family\ Size[/tex]
Substitute 12 fl oz for Family Size
[tex]Regular\ Size =75\% * 12\ fl\ oz[/tex]
Convert percentage to fraction
[tex]Regular\ Size = \frac{75}{100} * 12\ fl \oz[/tex]
[tex]Regular\ Size = \frac{75 * 12\ fl\ oz}{100}[/tex]
[tex]Regular\ Size = \frac{900\ fl\ oz}{100}[/tex]
[tex]Regular\ Size = 9\ fl\ oz[/tex]
Hence, the regular bottle holds 9 fl oz less

Peter has one of each of the following coins in his pocket: a penny, a nickel, a dime, a quarter, and a half-dollar. Four of these coins are taken out of the pocket and the sum of their values is calculated. How many different sums are possible?
Answer:
10
Step-by-step explanation:
This is a combinations problem, involving factorials.
5!/3!*2!=5*4/2=20/2=10
The different sum of the 4 coins from the list of 5 coins is an illustration of combination or selection. There are 5 different possible sums.
Given
[tex]n = 5[/tex] --- number of coins
[tex]r = 4[/tex] --- coins to be selected to calculate sum
For the sum of the coin value to be calculated, the 4 coins must be selected. This means combination.
So, we make use of:
[tex]^nC_r = \frac{n!}{(n - r)!r!}[/tex]
This gives
[tex]^5C_4 = \frac{5!}{(5 - 4)!4!}[/tex]
[tex]^5C_4 = \frac{5!}{1!4!}[/tex]
Expand
[tex]^5C_4 = \frac{5*4!}{1*4!}[/tex]
[tex]^5C_4 = \frac{5}{1}[/tex]
[tex]^5C_4 = 5[/tex]
Hence, there are 5 different possible sums.

372 to the nearest 100
Answer: 400
Explanation: To round 372 to the nearest hundred, we first find the digit in the rounding place which in this case is the 3 in the hundreds place.
To decide whether to round up or down, we look
at the digit to the right of the 3, which is 7.
According to the rules of rounding, if the digit to the right of the
rounding place is greater than or equal to 5, we round up.
So in this problem, since 7 is greater than or equal to 5, we round up.
This means that we add 1 to the 3 in the rounding place
to get 4 and all digits to the right of 4 become 0.
So 372 rounded to the nearest hundred is 400.

Hi there! Hopefully this helps!
------------------------------------------------------------------------------------------------------------
Answer: 2987
First we need to rewrite the equation. Since x = 23 and y = 36 the equation should look like this for easier steps:
25(23) + 67(36) = ?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Now since there numbers by other numbers in parentheses, we need to multiply them.
25 x 23 = 575.
67 x 36 = 2412.

Blank 1:
Blank 2:
Helppppp!!
Answer:
a. 1.25
b . 0.8
Step-by-step explanation:
This is a question in scale factors
a. The sable factor that takes P to Q
In P, we are having sides 4, 2 and 3
In Q, we are having sides 2.5 and 5
From the diagrams and using the similar sides, we can see that the side length 4 became 5 while the side length 2 became 2.5
So the scale factor would be;
4 * x = 5
or
2 * x = 2.5
Where x is that dilation factor that transformed 4 into 5
Thus, x would be 5/4 or 2.5/2 = 1.25
b. The scale factor that takes Q to P
This is the direct opposite of what we have in the first question.
Here, we want to go from Q to P
To get this, we simply divide what we have in P by what we had in Q
Hence, what we do here is;
2/2.5 or 4/5 = 0.8
