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).
Answer:
a monomial, a constant
Step-by-step explanation:
It has only 1 term, so it's a monomial.
Also, the term is a constant.
Barbara mixes 54 ounces of granola and 36 ounces of raisins:
54 ounces + 36 ounces = 90 ounces
Now, if you would like to divide this mixture into 6 ounces servings, you can do it like this:
90 ounces / 6 ounces = 15 servings
Result: Barbara makes 15 servings.

6. D
Step-by-step explanation:
4. The radius is 3 units (3 boxes). So you do pi*r^2 = 3.14*9
5. You want the area of the box minus the area of the two circles.
Height of the box is 8 (bottom of circle to the top is two times the radius). Width of the box is 16 (left end of the left circle to the right end of the right circle) so 4 times the radius of the circles. Area of box is 128
Area of each circle is 3.14*(16). So you do 128 - 2*3.14*16.
6. Just plug in the radius 9 to the area of a circle formula: pi*radius^2 = 81*pi
