Answer:

a 1

b 6

c 15

Step-by-step explanation:

101% 101/100 = 1 1/100

is 1 complete 100 grid and 1/100 of another grid so you will need 2 grids

589% 589/100 = 5 89/100

is 5 complete 100 grids and 89/100 of another grid so you will need 6 grids

1450% 1450/100 = 14 50/100

is 14 complete grids and 50/100 of another grid so you will need 15 grids

What is the slope and y-intercept of y+3= -1/3

bazaltina [42]

Assuming this is written correctly, with no x in the equation, we just solve for y:

y = -3 - 1/3 = -10/3 = 0 x - 10/3

That's slope-intercept form.

Answer: Slope 0, y-intercept -10/3

PLEASE HELP The volume of a cube is defined by the function, V(x), where the volume is measured in cubic meters. Find a polynomi

olya-2409 [2.1K]

we have

$V(x)=x^3-12x^2+48x-64$

we know that

The volume of a cube is equal to

$V=b^{3}$

where

b is the length side of a cube

Using a graph tool------> find the roots of the polynomial

see the attached figure

x=4

$x^3-12x^2+48x-64=(x-4)^{3}$

therefore

The answer is

the length side of a cube is equal to (x-4)

Question 1 options: 3 8 12 2.5

rewona [7]

Answer:

2.5

Step-by-step explanation:

(I'm assuming you're doing this the same way I learned it, if not I'm sorry if it doesn't make sense)

$\frac{2}{x}$ = $\frac{12}{15}$

Cross multiply

12x=30

Divide

x=2.5

This is just one way to do the problem. An easier way is to simplify the fractions.

$\frac{2}{x}$ = $\frac{4}{5}$

You can either cross multiply or figure out that 2 is half of four and simply divide 5 by 2 which will also result in 2.5
