Have a great rest of your day
#TheWizzer

Answer:  40 cars pass per minute.

Step-by-step explanation:

[tex]\frac{120cars}{3minutes\\}[/tex]  = [tex]\frac{?cars}{1minutes}[/tex]

        3? = 120  [cross multiply]

          ? = 40    [divided 3 from both side]

Therefore, 40 cars passes per minute.

The solution of the given equation [tex](4x-16)^{1/2} = 36[/tex] is 328.

The given equation is:

[tex](4x-16)^{1/2} = 36[/tex]

The solution of an equation is to find out the numeric value of the variable such that Left-hand side and Right-hand side becomes equal.

Squaring both sides of the given equation.

[tex][(4x-16)^{1/2} ]^2= (36)^2[/tex]

[tex]4x-16 = 36^{2}[/tex]

[tex]4x -16 =1296[/tex]

[tex]4x =1296+16[/tex]

[tex]4x = 1312[/tex]

x= 328

Therefore, The solution of the given equation [tex](4x-16)^{1/2} = 36[/tex] is 328.

Answer:

f(-8) = 57

Step-by-step explanation:

When x = - 8

f(-8) = 2 x (-8)² + 7 x (-8) - 15

f(-8) = 2 x 64 - 56 - 15

f(-8) = 128 - 56 - 15

f(-8) = 128 - 71

f(-8) = 57

[tex]\sf f(x) = 2x^2 + 7x - 1[/tex]

Just substitute the value of x as (-8) .

[tex]\sf f(-8) = 2(-8)^2 + 7(-8) - 15[/tex]

[tex]\sf f(-8) = 2(64) - 7(8) - 15[/tex]

[tex]\sf f(-8) = 128 - 56 - 15[/tex]

Answer: The number of books she should put on each shelf = 7

Step-by-step explanation:

Given: Total books = 116

Total shelves = 16

To determine : The number of books she should put on each shelf, we first divides the total number of books by the total shelf.

[tex]116\div 16=7\dfrac14[/tex]

So she can put 7 books in each shelf such that (7x16=) 112 books got placed and (116-112=)4 books left.

Hence, The number of books she should put on each shelf = 7.
