Salesman A works strictly on commission. He earns $65 per sale, with a maximum weekly commission of $1,300.

Salesman C does not earn any commission. His weekly salary is $900.

James borrows $35 from his father for gas, and then borrows $29 more for video games. What integer represents the amount of money that James owes his father?

Answers

Answer:

64

Step-by-step explanation:

You just have to add 35 and 29 and the answer is an integer cause it's a whole number.

Answer:

64

Step-by-step explanation:

You are adding more to the first integer 35, so you have to add the next integer 29 to it.

So, the equation would be 35 + 29

First, add 9 and 5 which is 14. Carry the 1 to the next part.

3+2=5

5+1=6

The end result is 64.

Which transformations were used to create a triangle JKL

Answers

The second one because the triangle prime is much smaller than the green one. And the reflection is towards the x axis

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).
