Answer: P =38.7 in, A=63.7in^2
Step-by-step explanation: start by using the formula for area of a triangle: A =bh/2 and plug in values given for the larger triangle to find the height. 115=9h/2,. 230 =9h h= 25.556
Subtract from perimeter to get an estimate of the third side: 62-34.556=27.45
Realize now that the drawing is not to scale!
Use the dimensions of the larger triangle to and the proportion 6.7/9 = smaller / larger to find other dimensions of the smaller triangle. Add the sides to get perimeter. Multiply bh/2 to get the Area. Choose the answer that is closest to your calculations as the numbers are estimated. We cannot assume that this is a right triangle.
Answer:
A. 525 in squared
Step-by-step explanation:
Fundamentally, the area of a parellelogram such as this can be calculated the same way the area of a normal rectangle is calculated: Length x Width.
Thus,
(27 + 8) x 15 = Area
35 x 15 = Area
525 = Area
Don't forget your units! (Inches squared)
A. Expanding the given expression, you have
balance = 75r^2 +150r +75
B. For r=0.10, the balance after 2 years is 75*1.1^2 = 90.75
C. The difference between $120 and 90.75 is $29.25. You need $29.25 more to buy the bicycle.
