Step-by-step explanation:
Answer:
70 m^2
Step-by-step explanation:
The key shows that each square side on the grid measures 2 m. The base of the triangle measures 7 grid square sides, so it measures 14 m. The height of the triangle measures 5 grid square sides, so it measures 10 m.
area of triangle = bh/2
area = (14 m)(10 m)/2
area = 140 m^2/2
area = 70 m^2
Answer:
x=-10
Step-by-step explanation:
6x+4=5x-6
Subtract 5x from each side
6x-5x+4=5x-5x-6
x +4 = -6
subtract 4 from each side
x+4-4 = -6-4
x=-10
First divide 76 by 8 since 8 people can fit in the cabin. That leaves 4 more people for tents. It will take 2 tents for the 4 people.
First find the area of the pizza:
area = PI x r^2
diameter = 16 inches...radius = 16 /2 =8 inches
area = 3.14 x 8^2 = 3.14 x 64 = 200.96 sq inches. Round to 201 square inches
the pizza has 6 calories per square inch so now multiple the total square inches by 6 to get total calories:
201 * 6 = 1206 total calories
now divide total calories by 144 to find the number of slices:
1206 / 144 = 8.375 so the pizza can be cut into 8 slices and each slice would have a little over 144 calories
