A health insurance payment of $34.55 was deducted from ms. Donaldson's earnings for the week. After the insurance deduction, payroll taxes equal to 28% of the balance were deducted. What was the amount that Ms. Donaldson received?

Answers

I think that this quesion is missing some background, that is that Ms. Donaldson earned 907.10

So the 34.55 were deduced from this number, and the remaining amount was:

907.10-34.55=872.65

After this, further 28% were deduced, which means that 100-28=72% were left.

And this is:72%*872.55= 628.236 (which we round to 628.24!)

 

Answer: the answer would be 628.24!

Look at this prism and its net. Rectangular prism with length labeled 5 meters, width labeled 7 meters, and height labeled 12 meters. Net of the same rectangular prism with the same dimensionsn labeled. What is the surface area of this rectangular prism?

Answers

There will be three pairs of matching sides: one pair 5x7, one pair 5x12 and one pair 12x7. We can compute the are of each side (in pairs) and then add up the total:

A_(surf)=2*(l * w)+2*(l * h)+2*(h * w)
A_(surf)=2*(5*7)+2*(5*12)+2*(12*7)
A_(surf)=2*35+2*60+2*84
A_(surf)=70+120+168
A_(surf)=358 
A_(surf)=358m^(2)

B. .50d+.25

Thanks so much if your respond!
I mostly need help on the name the property.

Answers

B.
This is something called the distributive property. How do you do that?

Multiply the number outside the parenthesis in this case; .25. to the number within the parenthesis; the coefficient "2d" and "1".

Therefore, it's .50d+.25. Hope this helps!
