The answer is:  [A]:  " 4 and 5 " .
______________________________
Explanation:
______________________________
Looking at the answers:
______________________________
 we know that 4² = 16 ; and 5² = 25 ;

So:  √16 = 4  ;  and √25 = 5.

So:  √21 must be between √16 and √25 ;

That is: √21 must be between 4 and 5 ; which is answer choice:  [A] .

What is the greatest common factor of the following monomials: 12g^5h^4 g^5h^2
muminat

Answer:

g^5h^2

Step-by-step explanation:

12g^5h^4, g^5h^2

This is one way of doing it. Break down every number and every variable into a product of the simplest factors. Then see how many of each factor appear in both monomials.

12g^5h^4 = 2 * 2 * 3 * g * g * g * g * g * h * h * h * h

g^5h^2 = g * g * g * g * g * h * h

So far you see every single prime factor of each monomial.

Now I will mark the ones that are present in both. Those are the common factors.

12g^5h^4 = 2 * 2 * 3 * g * g * g * g * g * h * h * h * h

g^5h^2 = g * g * g * g * g * h * h

The greatest common factor is the product of all the factors that appear in both monomials.

GCF = g * g * g * g * g * h * h = g^5h^2

Find an equation in slope-intercept form for the line with slope -3/4 and y-intercept=0? will give BRAINLIEST
nata0808 [166]

Answer:

Step-by-step explanation:

See the solution process below:

Explanation:

The slope-intercept form of a linear equation is:  y =mx+b

Where  m is the slope and b

is the y-intercept value.

We are given the slope in the problem so we can substitute

−5/6 for  m  in the formula.

And,

(0,6)

is the y-intercept so we can substitute

6

for

b

in the formula giving:

y

=

−

Ateacher uses 36 centimeters of tape to hang up 9 student projects. At that rate
Troyanec [42]

The teacher would need 40 centimeters of tape to hang 10 student projects.

Step-by-step explanation:

Given,

Tape used to hang projects = 36 centimeters

Number of projects hanged = 9

We will find unit rate;

9 projects = 36 centimeters

1 project = \frac{36}{9}\ centimeters

1 project = 4 centimeters

Therefore,

Tape needed to hang 10 projects = 4*10 = 40 centimeters

The teacher would need 40 centimeters of tape to hang 10 student projects.

Keywords: unit rate, multiplication
