Essie likes plants. She never misses a chance to go to the nursery section in Home Depot. Essie has a total of $65.50 to spend on her trips to the store over the next three days. On her second trip to the nursery she spent $15.50 dollars more than what she spent on the first trip to the store. On her third trip to the nursery she spent two times much as what she spent on her first trip to the nursery. How much did she spend on her first trip to the nursery? Create a linear equation to model a real-world situation and solve the equation to find the solution


Answers

Answer:

Step-by-step explanation:

Let $ x = the amount spent on the first day

The amount spent on the second day = x + 15.50

The amount spent on the third say = 2*x = 2x

Total amount Essie spent on 3 days = $65.50

x + (x +15.50) + 2x = 65.50

x + x + 15.50 + 2x = 65.50

Add like terms

4x + 15.50 = 65.50

Subtract 15.50 from both sides

4x = 65.50 - 15.50

4x = 50

Divide both sides by 4

x = 50/4

x = $ 12.50

The amount spent on the first day = $ 12.50

The amount spent on the second day = 12.50 + 15.50 = $ 28

The amount spent on the third day= 12.50 * 2 = $ 25

Step-by-step explanation:

total angle of a hexagon is 720. We know already 510°. That leaves 210°. The ratio between the two angles is 2:1, therefore angle CDE is 140° and angle DEF is 70 °

Answer:

140°

Step-by-step explanation:

We know that all of these angles here are part of a hexagon, meaning that their angle measures will all add up to 720°.

We can use what we already know and find what CDE and DEF will add up to.

[tex]145+90+160+115=510\\720-510=210[/tex]

Now, assuming x is the measure of DEF, we can create an equation for this.

[tex]x + 2x = 210\\3x = 210\\x = 70[/tex]

This is the measure of DEF, but it asks for CDE, which is twice the size of DEF. So

[tex]70\cdot2=140[/tex]

We can double check this is right by adding up all the measures.

[tex]145+90+160+115+140+70=720[/tex]

a car traveling at 87 km/h and a bus leave a toll booth at the same time. twenty minutes later the bus is 3 km farther from the toll booth than the car. what is the average speed of the bus

Answers

Answer:

96 km/h

Step-by-step explanation:

Speed of car = 87 km/h

Time = 20 minutes = [tex]\frac{20}{60} = \frac{1}{3}\ hrs[/tex]

Distance traveled by bus = 3 km more than that of traveled by car

To find

Average speed of bus = ?

Solution:

Formula for distance traveled is given as:

[tex]Distance = Speed \times Time[/tex]

So, distance traveled by car in 20 minutes = 87 [tex]\times \frac{1}3[/tex] = 29 km

As per given statement, distance traveled by bus = 29 + 3 = 32 km

Time taken = [tex]\frac{1}{3}\ hrs[/tex]

Using the formula:

[tex]Speed = \dfrac{Distance}{Time}[/tex]

Speed of the bus =

Find the value of x in the given
right triangle.
Enter your answer as a decimal rounded to the

Answers

Answer:

x = 12.5

Step-by-step explanation:

Since the figure above is a right angled triangle we can use trigonometric ratios to find x

To find x we use cosine

cos∅ = adjacent / hypotenuse

From the question

The hypotenuse is x

The adjacent is 10

Substitute these values into the above formula and solve for x

That's

[tex] \cos(37) = \frac{10}{x} [/tex][tex]x \cos(37) = 10[/tex]

Divide both sides by cos 37

[tex]x = \frac{10}{ \cos(37) } [/tex]

Find the missing probability: P(B)=7/20, P(A|B)=1/4, P(A∩B)=?

Answers

Answer:

P(A∩B) = 7/80

P(A∩B) = 0.0875

Step-by-step explanation:

Given

P(B)=7/20

P(A|B)=¼

Required

P(A∩B)=?

The given probability shows conditional probability and the relationship between the given parameters is as follows.

P(A∩B) = P(B) * P(A|B)

Substitute ¼ for P(A|B) and 7/20 for P(B)

The expression

P(A∩B) = P(B) * P(A|B) becomes

P(A∩B) = 7/20 * ¼

P(A∩B) = 7/80

P(A∩B) = 0.0875

Hence, the calculated P(A∩B) is 7/80 or 0.0875

At an elite baseball camp, 60% of players can bat both right-handed and left-handed. If 25% of the players who bat left-handed do not bat right-handed, what is the probability that a player selected at random does not bat left-handed?

Answers

Answer:

The probability that a player selected at random does not bat left-handed is 20%.

Step-by-step explanation:

Assume that there are a total of 100 baseball players at an elite baseball camp.

The information provided is:

60% of players can bat both right-handed and left-handed. 25% of the players who bat left-handed do not bat right-handed.

That is, the number of players can bat both right-handed and left-handed is,

n (L and R) = 60.

Now, if 25% of the players who bat left-handed do not bat right-handed, then 75% of all left-handed players can also bat right-handed.

⇒ n (L and R) = n (L) × 75%

            60     = n (L) × 0.75

           n (L)    =  60/0.75

           n (L)    = 80

So there are 80 left handed batters.

Compute the number of only left handed batters as follows:

n (Only L) = n (L) × 25%

                = 80 × 0.25

                = 20

So there are 20 only left handed batters.

Compute the number of only right handed batters as follows:

Total = n (Only L) + n (Only R) + n (L and R)

 100 = 20 + n (Only R) + 60

n (Only R) = 20

Thus, the probability that a player selected at random does not bat left-handed is 20%.

if the side length of a square can be represented by 4x + 4 and its area is 1024 square units, find the value of x

Answers

Answer:

x = 7

Step-by-step explanation:

Since it’s the area of a square, we can simply do square root of 1024. (Because to get area of square you do side x side). Which is 32.

So basically 4x + 4 = 32... x = 7

Answer:

x = 7

Step-by-step explanation:

A = 1024

side length of a square = 4x + 4

A = s²

s = √A

s = √1024

s = 32

using the side length to get the value of x

s = 32

4x + 4 = 32

4x = 32 - 4

x = 28 / 4

x = 7

check:

A = side length * side length

A = (4x + 4) * (4x + 4)

A = (4*7 + 4) * (4*7 + 4)

A = 32 * 32

A = 1024  ok

Answers

A = (15.5 - 11.9) / (110 - 30) = 3.6 / 80 = 0.045

Average rate of change = 0.045 cm

The average rate of change of sea urchin's diameter with respect to its age is 0.0045 cm/yr.

What is Derivative in mathematics?

Derivative in mathematics represent the rate of change of a function with respect to a variable.

Given is a red sea urchin such that at age 30, the urchin has a diameter of 11.9 cm whereas urchin at age 110 has a diameter of 15.5 cm.

From the question we can write -

Initial age = A[1] = 30

Initial diameter = D[1] = 11.9 cm

Final Age = A[2] = 110

Final diameter = D[2] = 15.5 cm

Average rate [r] = D[2] - D[1] / A[2] - A[1]

r =  D[2] - D[1] / A[2] - A[1]

r = 15.5 - 11.9/110 - 30

r = 3.6/80

r = 0.045

Therefore, the average rate of change of sea urchin's diameter with respect to its age is 0.0045 cm/yr.

The following frequency table shows the number of fish caught by each of Igor's family members. What was the maximum number of fish that a family member caught? _____ fish

Answers

Answer:

4

Step-by-step explanation:

The values on the left of the table represent the number of fish caught, and the number of the right of the table represents how many family members caught that amount of fish.

Therefore, the first row means that 0 family members caught 0 fish.

The second row means that 3 family members caught 1 fish.

The third row would mean 1 family member caught 2 fish.

The next row would mean 0 family members caught 3 fish.

And the final row would mean 4 family members caught 4 fish.

The question does not ask for the total amount of fish caught; rather is ask for the maximum number of fish that a single family member caught.

Therefore, the maximum amount of fish that a single family member catches is 4. (And 4 family members did so. But individually, the maximum amount of fish one person caught is 4).
