two hot air balloons are traveling along the same path away from a town, beginning from different locations at the same time. Henry´s balloon begins 30 miles from the town and is 48 miles from the town after 2 hours. The distance of Tasha´s balloon from the town is represented by the function y= 8x +20.
which balloon was farther from the town at the beginning, and which traveled more quickly?
Answers
9514 1404 393
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.

Step-by-step explanation:
the main equation would be
210+3x>288
first I divided 210 by 3 to see how many mugs he has sold first. Then I got an answer of 70 mugs sold. after that i subtracted 210 from 288 and got 78. After this I divided 78 by 3 to get a count of how many mugs Ronny needs to sell. so The total amount of mugs Ronny needs to sell to reach his goal of 288$ is 96. But he has already sold 70 so he needs to sell 26 more mugs.

The area of a 2D form is the amount of space within its perimeter. The total surface area of the square base pyramid is 297mm².
What is an area?The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm2, m2, and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.
The total surface area of the square pyramid is the sum of the area of the triangles and the area of the base. Therefore, the total surface area is equal to,
Total surface area = Area of square base + 4(Area of a triangular face)
= (9mm)² + 4(0.5×9×12)mm²
= 81mm² + 216mm²
= 297mm²
Hence, the total surface area of the square base pyramid is 297mm².
