What is the ratio of the number of beaks to the number of legs the chickens and the sheep have on this farm?
Answer: 1:9
Step-by-step explanation:
If you multiply 2 legs times 8 chickens we get 16
If you multiply 4 legs times 14 sheep we get 56
The number of legs is 16+56=72
So you have 8 beaks and 72 legs or 8:72
Divide both sides by 8 to simplify and you get 1:9 as the answer

Step-by-step explanation:
12a. y-y1=m(x-x1)
y-5=(2-5)/(1--3)(x--3)
y-5=-3/4(x+3)
4y-20=-3x-9
4y=-3x-9+20
4y=-3x+11
y=-¾x+11/4

Perpendicular lines have the product of their gradient equal to -1
For L1,the gradient is 3
For L2,we express in slope-intercept form
6y=1-2x
y=1/6-⅓x
The slope is -⅓
Now product of both slopes 3×-⅓=-1,thus the lines are perpendicular

If given 5 miles is 8km convert 13.5 miles into km
Step-by-step explanation:
There are 2 ways we can do this. We can use our friend which we will call a special device or we could actually solve using formulas we already know. Today, I will be using a formula but you can easily just use the secret device.
Step 1: Knowing the formula which is multiply miles by 1.609 and then round to the nearest tenth or hundredth.
13.5 X 1.609 = 21.7215.
Round down to 21.7.
Final Answer: 21.7 Km is equal to 13.5 miles or vice versa.
Allie says that the expressions 4x - 2x +4 and 2(x + 2) are not equivalent because one expression
has a term that is subtracted and the other does not. Do you agree? Explain.
Yes,
the expressions are equivalent. The first expression, 4x - 2x +4, can be simplified to
which equals 2(x + 2).
(Use the operation symbols in the math palette as needed.)
Answer:
the espression are equivalent
Step-by-step explanation:
4x - 2x + 4 = 2 (x + 2)
2x + 4 = 2x + 4

Answer:
0.01085 ~ 1.085%
Step-by-step explanation:
Okay so a simple way to do these probability ones is to add an extra space around each side
YES NO
POSITIVE 325 2 _____
NEGATIVE 16 1131 _____
_____ _____ _____
Now in these spaces add all the the rows and columns accordingly
YES NO
POSITIVE 325 2 _327_
NEGATIVE 16 1131 _1147_
_341_ _1133_ _1474_
Now the number in the place where the additional rows meet is your total number of patients, so this is what you would use for your probability.
So we are looking for YES / NEGATIVE which is 16
Now do 16 divided by 1474 and your probability comes out to 0.01085..., so as a percentage, would be 1.085%
Hope that helped :)

First Question:
[tex]\sqrt{100}[/tex] + [18 ÷ 3 x 4 - 15] - (60 - 7^2 - 1)
[tex]\sqrt{100}[/tex] + [24 - 15] - (60 - 49 - 1)
[tex]\sqrt{100}[/tex] + 9 - 10
10 + 9 - 10
Answer = 9
Second Question:
5x + 2x = 7x
5x^2 + 3x^2 = 8x^2
2x + 3x - x = 4x
2x + 3y + x + y = 3x + 4y
9x - 6x = 3x
-7y + 3x + 4x + 3y = 7x - 4y
-7x^2 + 2x^2 + 9x^2 = 8x^2
(3x^2 + 5x + 4) - (-1 + x^2) = 2x^2 + 5x + 5
(3 + 2x - x^2) + (x^2 + 8x + 5) = 10x + 8
(3x - 4) - (5x + 2) = -2x - 6
(2x^2 + 5x + 3) - (x^2 - 2x + 3) = x^2 + 7x
(3x^2 + 2x - 5) - (2x^2 - x - 4) = x^2 + 3x - 1
Third Question:
17x + 2y
(5x + 12y) + (3x + y) = 8x + 13y
17x - 8x = 9x
2y - 13y = -11y
Answer: 9x - 11y

Multiply 28.95 by 3. You get 86.85Subtract 86.85 from 100. You get 13.15Divide 13.15 by 0.25. You get 52.006solve pls brainliest
Answer:
[tex]18 {m}^{2} [/tex]
Step-by-step explanation:
[tex]area \: = 6m \times 4m \\ = 24 {m}^{2} \\ \\ grass \: area = 3m \times 2m \\ = 6 {m}^{2} \\ \\ cement \: area \: = 24 {m}^{2} - 6 {m}^{2} \\ = 18 {m}^{2} [/tex]
Answer:
18 m^2
Step by step explanation:
In these types of math problems, we have two ways to solve.
1) Directly find the area of the shaded area.
2)Find the unshaded area and then minus that from the total area.
In this case, I will use the second way.
The grass area (unshaded) is 3 x 2 = 6 m^2 ( 6 square meters )
The total area (grass + cement) is 4 x 6 = 24 m^2 ( 24 square meters )
Now, we want the area of the cement part but the grass's area is also in the total.
So, we minus 6m^2 from 24m^2.
Then we get 18m^2.
And that is the answer.
I hope it helps.
(Note : because this problem is easy, you can use both ways but most use the second way. There may also be problems where we can use only the first or second way.)
Jonas has bought three t-shirts. Each t-shirt was the same price. After using a 10% off coupon the total charge was 95 what was the cost of each t-shirt
Answer:
35 5/27
Step-by-step explanation:
You just have to set up an equation:
0.9/95 = 1/x
And if you cross-multiply, you get:
0.9x=95
Which means x is 95/0.9 which is 105 5/9. So, if all three t-shirts costed 105 5/9, and they all costed the same, then one t-shirt costs 35 5/27.
support this claim with evidence:
claim: Integers are commonly used in describing temperature above or below freezing point it is also describes dept. or money or even sea levels above or below sea levels.
All of those claims are true.
We can describe positive temperatures such as room temperature (20 degrees C = 68 degrees F), and we can have negative temperatures as well (eg: -40 degrees C = -40 degrees F). The only time we cannot have negative temperature is when you use the Kelvin temperature scale. This is because absolute 0 represents the coldest possible temperature in the universe. In more common settings, Celsius and Fahrenheit are frequently used.
Debt and money are often involving negative integers. If we were to write -7 in terms of money, then it could represent a person owing $7. Positive values represent having the actual money and not being in debt.
When it comes to elevations, positive integers represent being above sea level; while negative values are below sea level. For example, Mount Everest is +29035 above sea level (or simply 29035 ft) and the Mariana Trench roughly has an elevation of -36201 ft (meaning it's about 36201 ft below sea level).
Which angles are adjacent to each other? Question is located in the attached file (image)
Answer:
∠ 1 and ∠2
Step-by-step explanation:
Adjacent angles share a common ray or side between them, and have the same vertex.
Therefore, the adjacent angles from the given image are: ∠ 1 and ∠2.
The other given options are not adjacent angles because they do not have the same common vertex and ray.

Answer:
3 recipes/week
Step-by-step explanation:
Pick any two points where the line passes to a point in the grid, so you don't go crazy with counts. That means (0.0) (1;3) (2;6) (3;9) Pick two of them, in order. Let's say we like (0.0) and (1.3) since we're lazy. Now let's subtract the second part of each pair, (in our case, 0-3), do it for the first pair (in our case 0-1) and divide the two results: [tex]{-3 \over -1} = 3[/tex] Feel free to pick any other two and double check, being careful you're always doing [tex]\Delta y \over \Delta x[/tex]
I’m not sure about this problem could anybody help me ? PROBLEM : 3andb = 7: (a−b)3
The given question requires the expansion of the expressions within the bracket to the stated power. This would give an answer that is equal to -64.
This expansion requires the substitution of the given values, a and b, into the expression in the bracket. Then expanding the determined answer to the stated power.
Here, subtract the value of b from that of a, then expand the answer to the power of 3.
Thus:
[tex](a - b)^{3}[/tex]
Given that; a = 3, and b = 7, then we have:
[tex](a - b)^{3}[/tex] = [tex](3 - 7)^{3}[/tex]
= [tex](-4)^{3}[/tex]
= -4 * -4 * -4
= -64
Therefore with the given conditions in the question, we have:
[tex](3 - 7)^{3}[/tex] = -64

93 A carpenter has two different boards
measuring 80 inches and 64 inches. If the
carpenter cuts them into equally sized
pieces and has no wood left over, have long
will each piece be?
Answer:
Each piece will be 8 inches
Step-by-step explanation:
We have to find the HCF / GCF of 80 and 64
80 = 2 * 2 * 2 * 2 * 5
64 = 2 * 2 * 2 * 2 * 2 * 2
HCF = 2 *2 *2 = 8
80 inches = 8 * 10 . So, 10 boards each measuring 8 inches
64 = 8 * 8 . So, 8 boards each measuring 8 inches

Answer:
x= 1 and y =1
Step-by-step explanation:
4+4 is 8, therefore for this to be true both must be 1
Answer:
x = 1; y = 1
Step-by-step explanation:
We know x and y have to equal the same thing because 4 + 4 = 8
x = 4 / 4
y = 4 / 4
x = 1
y = 1
Therefore, x = 1; y = 1
