3 0

Answer:

Raj will take 10 minutes

explanation:-

Raj types 20 words per minute

Saleem types 40 words per minute

I. e speed and time are inversly proportional.

therefore, Raj will take twice the time Saleem takes.

Raj takes 2 * 5 = 10 minutes

Which can be used to describe the expression? Check all that apply.
frozen [14]
We can write the expression above as the following function:

f(r)=(r-4)^{3}

So let's examine the expressions that are true for this exercise.

1. <span>There are three factors of r-4:

This is true because we can write the function f(r) as follows:

</span>f(r)=(r-4)(r-4)(r-4)

So you can see that in fact there are three factors.

<span>2. The expression is equal to 1 over 12 factors of r.

This is false. It is obvious that this is impossible. There is no any way to get the same expression by applying this statement.
</span>
3. <span>Adding the exponents will create an equivalent expression.

This is true because we can write the function as follows:

</span>f(r)=(r-4)^{1+1+1}

So adding one three times we can get the same function, that is:

1+1+1=3

Therefore this is an equivalent expression because:

f(r)=(r-4)^{1+1+1}=(r-4)^{3}

4. Multiplying the exponents will create an equivalent expression.

This is true.You can get the following expression:

f(r)=(r-4)^{\frac{2}{3}\times \frac{9}{2}}

By multiplying the exponents we have:

\frac{2}{3}\times \frac{9}{2}=3

Therefore this is an equivalent expression because:

f(r)=(r-4)^{\frac{2}{3}\times \frac{9}{2}}=(r-4)^{3}

5. <span>The expression simplifies to.

The expression is simplified, that is, it has been factorized. Therefore there is no a way to simplify this function but:

</span>f(r)=(r-4)^{3}

The ratio of two numbers is 3:5. When 4 is subtracted from the lesser of the two numbers and 8 is added to the larger of the two
irinina [24]
X and y
x:y=3:5
or
x/y=3/5


when 4 is subtracted from x and 8 is added to y new ratio is 2:7
(x-4)/(y+8)=2/7



we have
x/y=3/5
(x-4)/(y+8)=2/7


get rid o frationc

x/y=3/5
times both sides by 5y
5x=3y

(x-4)/(y+8)=2/7
times both sides by 7(y+8)
7(x-4)=2(y+8)
7x-28=2y+16
add 28 both sides
7x=44+2y

we have
5x=3y
and
7x=2y+44


multiply first equation by 2 and seecond equaiton by 3
10x=6y and 21x=6y+132

sub 10x for 6y
21x=10x+132
minus 10x both sides
11x=132
divide both sides by 11
x=12

x/y=3/5
12/y=3/5
times both sides by 5y
60=3y
divide both sid esyb 3
20=y

12 and 20

the greater is 20
