Answer:

20%

Step-by-step explanation:

  1. Set up a proportion: \frac{280}{1400} = \frac{x}{100}  
  2. Cross multiply, then divide: 280 × 100 = 28000, 28000 ÷ 1400 = 20
  3. So, 20% were satisfied with their car

I hope this helps!

Find the positive square roots of the following numbers, giving your answers in prime factorization form
Ket [755]

Hello from MrBillDoesMath!

Answer:

prime factorization of sqrt( 5^4 x 7^2)   =  (5^2) *7

prime factorization of sqrt(2^6 x 11^10)   =  (2^3) * (11^5)


Discussion:

sqrt( 5^4 x 7^2)  = 5^2 * 7    => as 5 and 7 are prime numbers

prime factorization = 5^2 *7


sqrt(2^6 x 11^10)  = 2^3 * 11^5   => as 2 and 11 are prime numbers

prime factorization = 2^3 * 11^5



Thank you,

A class has 8 boys and x girls. Each student has 4 pencils. The total number of pencils the students is 52.Create an equation th
diamong [38]

8 boys, x girls, 4 pencils each, total number of pencils 52.

The equation can be 4(8+x) = 52

So lets solve:

4(8+x)=52

Divide 4 on both sides:

8 + x=52 / 4

8 + x = 13

Subtract on both sides:

x = 13 - 8

x = 5

There are 5 girls in the class.

Now lets solve to double check:

4(8+5)=52

4(13)=52

52 = 52

Yes!

This means that there are 5 girls in the class.

I hope this helps! :)
