Answer:height 2 volume 24 will be r=3.39in
Step-by-step explanation:
-The area of A is 647 beacuase 16*12 is 192 and 13*35 is 455 and 455+192 is 647.The perimeter is A is 120 because 16+25+12+19+35+13 is 120.
-The area of B is 192 because 8*12+8*12 is 192.The perimeter of B is 70 because 8+12+8+7+8+12+8+7 is 70.
Answer: D. 0.8125
Step-by-step explanation: His expenses is $975, and his salary is $1200. Divide the expenses by the salary to find the debt-to-income ratio.
975/1200 = 0.8125
The debt-to-income ratio is 0.8125.
Answer:
Left triangle: 12.5 cm
Right triangle: 21 cm
Trapezoid: 50 cm
Total: 83.5
Step-by-step explanation:
Left triangle: The formula to find the area of a triangle is 1/2bh, in which b=base and h=height. The base of the left triangle is 5 cm and the height is 5 cm. 5*5=25. 25/2=12.5 cm.
Right triangle: Once again, use the area formula for a triangle. The base of the right triangle is 6 cm and the height is 5+2=7. 6*7=42. 42/2=21 cm.
Trapezoid: The formula to find the area of a trapezoid is a+b/2(h) in which a and b are the top and bottom of the trapezoid and h=height. In this case, a=9 cm and b=5+6=11 cm. The height is 5 cm. 9+11=20. 20/2=10. 10*5=50 cm.
Add all of the areas. 12.5+21+50=83.5. So, the total area is 83.5 cm.
