Marcus drew a scale drawing of the rectangular park in his neighborhood. On his drawing, the length of the park is 8 inches and
the width of the park is 6 inches. The key on his drawing shows 1 inch = 20 feet. What is the actual area of the park? ___8in___ | l 6in |________l
1 answer:
Answer:
19200 ft
Step-by-step explanation:
first you convert it based on 1 in = 20 ft
8*20=160
6*20=120
now you multiply to find area
remember area is a = lw
160*120=19200
add units
19200 ft

to get the numbers in step 3
multiply -1.6 by 3
then multiply -1.6 by 0.1
and add them together
answer is D) (–1.6)(3) + (–1.6)(0.1)
a+b+c=9 and a2+b2+c2=35 then by using identity
(a+b+c)2=a2+b2+c2+2ab+2bc+2ca,we get the answer 9x9=35+2(ab+bc+ca)
2(ab+bc+ca)=9x9-35
2(ab+bc+ca) =81-35then we get ab+bc+ca=46/2 so ab+bc+ca=23
3/5 x2= 6/10
