Answer:
34 classes
Step-by-step explanation:
First, subract 180 from 1200. You should get 1020. then do 1020/30. So 34 classes can watch the performance of 180 students.
It is rounded down to 151.

Answer:
D. Henry's started farther, went faster
Step-by-step explanation:
Henry's balloon traveled 18 additional miles (from 30 to 48) in 2 hours, so had a speed of 18mi/(2h) = 9 mi/h. The equation for his position could be ...
y = 9x +30 . . . . . 9 is the rate of change; 30 is the initial value
__
Comparing this to Tasha's position function, we see her balloon started 20 miles from town and traveled 8 miles per hour.
__
Henry started farther from town and traveled faster.
Answer:
The correct answer is second option
380 square feet
Step-by-step explanation:
Area of composite solid = Base area + area of side rectangles + area of triangles
<u>To find the area of base</u>
Base area = length * width
= 10 * 10 = 100 ft²
<u>To find the area of side rectangle</u>
There are 4 rectangles with length 10 ft and width 6 ft
Area = 4 * area of one rectangle
= 4 * (10 * 6)
= 240 ft²
<u>To find the area of triangle</u>
Here base of triangle = 10 ft and height = 7 ft
Area of 4 triangles =4 * area of single triangle = 4 * (bh)/2
= 4 *(10 * 7)/2 = 140 ft²
To find the total area = Base area + area of side rectangles + area of triangles
= 100 + 240 + 140
= 380 square feet
The correct answer is second option
380 square feet
