The math department needs to buy new textbooks and laptops for the computer science classroom. The textbooks cost $116.00 each,

Oksana_A [137]

Answer:

6 laptops.

Step-by-step explanation:

$6500 is the budget. If each textbook costs $116, and 30 textbooks are needed, you multiply.

116 x 30 = 3480.

3480 was spent on the textbooks, and the rest needs to go into laptops.

6500 - 3480 = 3020.

Now to find out how many laptops can be bought with the remaining money, divide.

3020 / 439 = 6.88 (You can't buy a portion of a laptop, so you have to take the biggest whole number, which is 6).

Use the Pythagorean theorem to find the length of the leg in the triangle below. side a is 35 , and side c is 21. What is B?

garri49 [273]

Answer:

b=-784!

Step-by-step explanation:

If pythagorean theorem is the following (see below), then we can work backwards in order to solve for b!

$a^{2} +b^2=c^2$

$35^2 +b=21^2\\1225+b=441$

Now all that's left is to subtract 1225 and we should have our answer!

$b=-784!$
