5% of 560 is 588,
150% of 588 is 882,
and then 882 divided by 200 is 4.18 (or 4.19)

Nate and 2 friends share a pizza equally. If Nate eats half of his share of the pizza, what fraction did he eat
Answer:
1/3
Step-by-step explanation:
Because the pizza was with him and his 2 friends.
Hope this helps:)
Nate eats 1/6 of the pizza. So, the required fraction is 1/6. To understand the calculations, check below.
Fraction:Important information:
Nate and 2 friends share a pizza equally.He eats half of his share of the pizza.The total number of persons is 3.
So, each of them is getting [tex]\dfrac{1}{3}[/tex] of a pizza.
It is given that Nate eats half of his share of the pizza. So, the half of his share is:
[tex]\dfrac{1}{2}\times \dfrac{1}{3}=\dfrac{1}{6}[/tex]
Therefore, Nate eats 1/6 of the pizza and the required fraction is 1/6.

Which transformations were used to create a triangle JKL
The transformation used to create K'L'M' would be, dilation by a scale factor 1/2 and reflection across the x-axis.
What is transformation?"Transformations are change in the original shapes on a coordinate plane by rotation, reflection or translation. "
What is reflection transformation?"It is a transformation which produces mirror image of geometrical structure."
What is dilation?"It is a transformation in which size of the geometrical structure is changed without changing its shape."
From given diagram,
we can observe that JK = 4 and J'K' = 2
This means the size of the triangle J'K'L' is reduced by 1/2
Also, it is reflected along x-axis.
This means, the transformation used to create triangle K'L'M' would be, dilation by a scale factor 1/2 and reflection across the x-axis.
Therefore, the correct answer is option (B).

Answer:
Step-by-step explanation:
First we have to find their hourly rate. We do this by dividing their total over 4 hours by 4 to get over just 1 hour.
60 / 4 = 15
Now we divide their total of $210 by their hourly rate of $15 to find how many hours it would take.
210 / 15 = 14
