Zak has 3/5 pack of pencils. Of these, 2/7 are blue. How many blue pencils does Zak have?
Basile [38]

Answer:

11/35

Step-by-step explanation:

First, you would have to make a common denominator. To do this, multiply these 2 denominator, 5 and 7. You should get 35. Then, you would have to make the numerator equal to the denominator. In this case, multiply 3 to 7 and 2 to 5. Now you have 21/35 and 10/35. Now subtract 21 from 10, and simplify if needed. I hope this helps!

Write the recurring decimal 0.05 as a fraction in its simplest form
lidiya [134]

Answer:

1/20

Step-by-step explanation:

Step 1: Write the given number as the numerator and place 1 in the denominator right below the decimal point followed by the number of zeros required accordingly.

In this case, 0.05 has two numbers after the decimal, so, we place 100 in the denominator and remove the decimal point. This will make it 5/100

Step 2: Then, this fraction can be simplified. 5/100 = 1/20

Thus, 0.05 as a fraction is written as 1/20

A sled starts at rest with 51,450 j of potential energy. after traveling part of the way down the slope, the sled has 32,781 j o
I am Lyosha [343]
In a mechanical system, it is a law that energy should be conserved. In this case, what is the initial energy should be equal to the total energy after the motion happened. We do as follows:

PE(at rest) = KE(during motion) + PE(after motion)
51450 J = KE(during motion)  + 32781 J
KE(during motion) = 18669 J

Simplify radical expression <br><br> √10z^5 - z^2 √10z
SCORPION-xisa [38]

Answer:

√10z^3(z - 1)(z + 1).

Step-by-step explanation:

The GCF is √10z* z^2

= √10z^3

So factoring we get

√10z^3(z^2 - 1)           The expression in brackets is difference of 2 squares so:

= √10z^3(z - 1)(z + 1)
