45 girls tried out for the field hockey team. 20% of the girls who tried out did not make the team. How many girls did not make the team?

It lagged earlier when I first asked

Answers

Answer 1

Answer:

9 girls did not make the team

Step-by-step explanation:

20*45=900

900/100=9

Answer 2

Answer:

9 girls didn't make the team

Step-by-step explanation:

The person above did it a great way, and that is the way I use it, but if you want a method that involves fractions here it is: 20% is the same as 1/5. Since there are 45 girls total, we need to find 1/5 of 45 and you can achieve that by multiplying 45 by 1/5 and you get 45/5 which is 9. Hope this helped :) .

Given the definitions of f(x) and g(x) below, find the value of f(g(5)).
N
f(x) = 2x² + 7x + 4
g(2) -x+ 5

Answers

Answer:

f(g(5)) = 4

Step-by-step explanation:

It says to find the value of f(g(5)). In this case, we first have to find g(5).

Plug 5 into g(x) = -x+5

g(5) = 0

Now, f(g(5)) is f(0), since g(5) was found out to be 0.

Plug in 0 into 2x² + 7x + 4

2(0)² + 7(0) + 4 = 0 + 0 + 4 = 4

Your mixing blue paint and yellow paint to get a total of 28 gallons. You want to use 7 times yellow paint as blue. How many gallons of each should you use ?

Answers

Answer:

B = Blue paint = 3.5 gallons

Y= Yellow paint = 24.5 gallons

Step-by-step explanation:

Let B = Blue paint

Y= Yellow paint

Your mixing blue paint and yellow paint to get a total of 28 gallons.

B + Y = 28 gallons

You want to use 7 times yellow paint as blue.

This means, 7B = Y

How many gallons of each should you use ?

Hence,

B + Y = 28

B + 7B = 28

8B = 28

B = 28/8

B = 3.5 gallons

B + Y = 28 gallons

Y + 3.5 gallons = 28 gallons

Y = 28 gallons - 3.5 gallons

Y = 24.5 gallons

B = Blue paint = 3.5 gallons

Y= Yellow paint = 24.5 gallons

Beth was working at the grocery store, in the quick check-out line. A customer bought cereal for $3.29 and milk for $3.45. The customer paid with $10.00. How much change does Beth need to give the customer?

Answers

Answer:

Change = $3.26

Step-by-step explanation:

Given the following data;

Cost of cereal = $3.29.

Cost of milk = $3.45.

Amount paid = $10.00

Total cost of items bought = $3.29 + $3.45 = $6.74

Change = Amount paid - Total cost of items purchased.

Substituting into the equation, we have;

Change = $10.00 - $6.74

Change = $3.26

Therefore, Beth need to give the customer a change of $3.26.

Given that Cos A=513and angle A is acute. Find the value of 2tan A + 3sin A without using a calculators.

Answers

Answer:

This implies that

x2+2ax=4x−4a−13

or

x2+2ax−4x+4a+13=0

or

x2+(2a−4)x+(4a+13)=0

Since the equation has just one solution instead of the usual two distinct solutions, then the two solutions must be same i.e. discriminant = 0.

Hence we get that

(2a−4)2=4⋅1⋅(4a+13)

or

4a2−16a+16=16a+52

or

4a2−32a−36=0

or

(a−9)(a+1)=0

Step-by-step explanation:

Using the trigonometric identity

sin²A + cos²A = 1 , then

sinA = [tex]\sqrt{1-cos^2A}[/tex] thus

sinA = [tex]\sqrt{1-(5/13)^2}[/tex]

        = [tex]\sqrt{1-\frac{25}{169} }[/tex]

        = [tex]\sqrt{\frac{144}{169} }[/tex] = [tex]\frac{12}{13}[/tex] , then

tanA = [tex]\frac{sinA}{cosA}[/tex] = [tex]\frac{\frac{12}{13} }{\frac{5}{13} }[/tex] = [tex]\frac{12}{5}[/tex]

Thus

2tanA + 3sinA

= 2 × [tex]\frac{12}{5}[/tex] + ( 3 × [tex]\frac{12}{13}[/tex] )

= [tex]\frac{24}{5}[/tex] + [tex]\frac{36}{13}[/tex]

what is the answer to the question?​

Answers

Answer:

Given : PQ = RQ

to find : angle B

PQ = RQAngle B = angle QRP ( angle opposite to equal side are equal). ...(1)angle QRP + 140° = 180° ( linear pair)angle QRP = 180° - 140°angle QRP = 40°from equation (1) Angle B = angle QRP = 40°

Answer:

b=40

Step-by-step explanation:

PQ=RQ

That means both sides are the same length which also means they both have the same angel measure of 140.

A super easy way to solve this would be to realize that where p is, the angel is 140.

A straight line is 180.

b and 140 are supplementary angels. [which means they equal 180]

To find b you can make an equation.

b+140=180

or

180-140=b

I'll show you both.

First one you would subtract 140 on both sides to get the variable alone, leaving you with b=40.

For the second one, you just do 180-140 and it also equals 40.

Either way it leaves you with b=40

If you need any more help with angels and whatnot, don't be afraid to reach out. I hope that helps! <3

Now, we proceed to find the area of "b". We already have the length x=15.9, so:  

Tan(α)=opposite leg/adjacent leg

yb=15.90xTan(42°)

yb=14.3

Area(b)=15.9X14.3/2

Area(b)=113.7

The total Area (At) is:  

At=Area(a)+Area(b)

At=248.0+113.7

As we can see in the exercises, all the triangles are divided in two triangles. So, let's call "a" to the triangle on the left and "b" to the triangle on the right.

Bruce retiled his kitchen. Originally, he bought three boxes of tile with the same number of tiles in each. He ran out of tile and had to go back to get three extra boxes of tile. However, he only used two tiles from the last box to finish the job.

Felicia also retiled her kitchen. She bought five boxes of tile with the same number of tiles that were in each as Bruce’s boxes. She also ran out of tile. She had to go back to the store and get an extra five tiles to finish the job.

In this activity, you will determine whether Bruce and Felicia used the same number of tiles and whose tiles cover the most area per tile.
Question - Is it possible for Bruce and Felicia to have used the same number of tiles? Use complete sentences to explain your reasoning.

Yes

Step-by-step explanation:

the equation for Bruce would be 3b+3b-2= numbers of tiles used.

and Felocias equation would be 5b+5= numbers of tiles used

so therefore if there were 7 tiles in each box they both could have used the same number of tiles

In other words, we need to check:

at x = 2, what is the value of y?

From the graph, it is clear that at x = 2, the value of y = -5
