Hey there! :D

If 20 is 25% of a number,

we know that it is a quarter of a number.

20*4= 80

20 is 25% of 80.

I hope this helps!

The data displayed by the graph indicate that in 2000,

Using an linear function, we find that by 2020 only 11% of all American adults believe that most qualified students get to attend college.

-----------------------------------------

A decaying linear function has the following format:

$A(t) = A(0) - mt$

In which

A(0) is the initial amount.
m is the slope, that is, the yearly decay.

In 2000, 45% believed, thus, $A(0) = 45$
Decaying by 1.7 each year, thus $m = 1.7$ .

The equation is:

$A(t) = 45 - 1.7t$

It will be 11% in t years after 2000, considering t for which A(t) = 11, that is:

$11 = 45 - 1.7t$

$1.7t = 34$

$t = \frac{34}{1.7}$

$t = 20$

2000 + 20 = 2020

By 2020 only 11% of all American adults believe that most qualified students get to attend college.

How do you divide a whole number by a fraction

lord [1]

Answer:Multiply the denominator on the bottom of the fraction by the whole number you are dividing by.

To divide a fraction by a whole number, multiply the bottom of the fraction by this whole number.

The denominator on the bottom of the fraction is 7.

We will multiply 7 by 2.

7 × 2 = 14 and so, 6 / 7 ÷ 2 = 6 / 14 .

SIZIF [17.4K]

Answer:

x = 4

Step-by-step explanation:

Given

5(2x - 1) = 35 ( divide both sides by 5 )

2x - 1 = 7 ( add 1 to both sides )

2x = 8 ( divide both sides by 2 )

x = 4

PLEASE SOLVE THIS FOR ME ITS DUE TOMORROW <br><br>Find an expression for the missing dimension.

denis-greek [22]

Answer:

The missing length is 2x+5

Step-by-step explanation:

Given equation of volume of cuboid is V= $2x^{3} +17x^{2} +46x+40$

Figure show that

Length of cuboid is ?

Width of cuboid is (x+4)

Height of cuboid is (x+2)

The volume of cuboid is given by

V=Length x Width x Height

Let Length be (bx+a)

The volume of cuboid will be

$V=(bx+a)(x+4)(x+2)$

$V=(bx+a)[x^{2}+4x+2x+8 ]$

$V=bx[x^{2}+6x+8]+a[x^{2}+6x+8]$

$V=[bx^{3}+6bx^{2}+8bx]+[ax^{2}+6ax+8a]$

$V=[bx^{3}+(6b+a)x^{2}+(8b+6a)x+8a]$

On comparing coefficient with given equation of volume

We get,

b=2 and 8a=40

Therefore, the value of a is 5 and b is 2

Thus, The missing length is bx+a=2x+5
