Answer:

15) f = 18

3f = 54

6f = 108

16) k = 69

Step-by-step explanation:

15)

3f + 6f + f = 180

10f= 180

f = 18

16)

42 + k + k = 180

42 + 2k = 180

2k = 138

k = 69

Answer:

x^7

Step-by-step explanation:

You just add the exponents when it's multiplying like that.

Answer:

x^7

Step-by-step explanation:

x^5*x^2 = (x*x*x*x*x)*(x*x)

We will count the number of x.

x^7

Answer:

Step-by-step explanation:

Well you didn't give directions on what to solve for,

I'm gonna assume you want to solve for y

x = (y/2) - 1 (add 1 to both sides)

x + 1 = y/2 (multiply both sides by 2)

2(x + 1) = y (distribute the 2)

y = 2x + 2

The expression 8(5t+7v) is equivalent to the expression 2(20t+28V) and 40t + 56v option (A) and option (D) is correct.

The distributive property is the property that expresses the distributive law of algebraic multiplication. similarly, in polynomial expression we can use the distributive property for example we can write a(c+b) in the form of (ac+bc).

We have an expression:

= 8(5t+7v)

After using the distributive property, we get:

= 8×5t+8×7v

= 40t + 56v

Applying distributive property in the expression 2(20t+28v), we get:

= 2×20t+2×28v

= 40t+56v

The above expression is equivalent to the given expression.

Again applying distributive property in the expression 4(95+11v), we get:

= 4×95+4×11v

= 380+44v

The above expression is not equivalent to the given expression.

The expression 40t+7v is not equivalent to the given expression.

The expression 40t+56v is equivalent to the given expression.

Thus, the expression 8(5t+7v) is equivalent to the expression 2(20t+28V) and 40t + 56v option (A) and option (D) is correct.

Answer:

D. 65%

Step-by-step explanation:

x%/100% = 13/20

Answer:

There are 40 books total

Step-by-step explanation:

you need to set a proportion

The first fraction is 55/100 it's over 100 because it's percent

the other fraction is 22/x the 22 is out of a total number so that's why it's on top and x because you don't know the total number of books

then you multiply diagonally

55×x= 22×100

55x=2,200

Then you solve it like a regular equation by dividing both sides by 55

x=40

Answer:

There are a total of 40 books in the box.

Answer:

36 feet

Step-by-step explanation:

3ft is 1 yard so you would multiply the 12 yards by 3 making 36.

Answer:

36 feet

Step-by-step explanation:

if 3 feet is equal to 1 yard which means by multiplying 12 by 3 (12x3) you would get 36 feet as your answer

Answer:

Step-by-step explanation:

A graphing calculator provides a nice answer for these questions. It shows the maximum height is 48.6 feet, and the time in air is 3.4 seconds.

__

The equation can be rewritten to vertex form to find the maximum height.

  h(t) = -16(t^2 -54/16t) +3 . . . . . group t-terms

  h(t) = -16(t^2 -54/16t +(27/16)^2) + 3 + 27^2/16

  h(t) = -16(t -27/16)^2 +48 9/16

The maximum height is 48 9/16 feet, about 48.6 feet.

__

The air time is found at the value of t that makes h(t) = 0.

  0 = -16(t -27/16)^2 +48 9/16

  (-48 9/16)/(-16) = (t -27/16)^2 . . . . . . . subtract 48 9/16 and divide by -16

  (√777 +27)/16 = t ≈ 3.4297 . . . . . square root and add 27/16

The time in air is about 3.4 seconds.

Answer:

yum

Step-by-step explanation:

Answer: 'Percent (%)' means 'out of one hundred':

p% = p 'out of one hundred',

p% is read p 'percent',

p% = p/100 = p ÷ 100.

8% = 8/100 = 8 ÷ 100 = 0.08.

100% = 100/100 = 100 ÷ 100 = 1.

Step-by-step explanation:

To calculate percentage decrease:

First: work out the difference (decrease) between the two numbers you are comparing. Then: divide the decrease by the original number and multiply the answer by 100. If your answer is a negative number, then this is a percentage increase.

Answer:

305

Step-by-step explanation:

43*8=344

234/6=39

344-39=305

Since the equation is [tex](43\times 8) - (234\div 6)[/tex] so after solving it, the answer is to be considered as the 305.

Since the equation is [tex](43\times 8) - (234\div 6)[/tex]

So,

we have to solve it

= 344 - 39

= 305

Hence, Since the equation is [tex](43\times 8) - (234\div 6)[/tex] so after solving it, the answer is to be considered as the 305.
