We just have to solve to get a simplified answer
we have
9y + 5 = 7 + 3y + 2y
9y +5 = 7 + 5y
9y-5y= 7-5
4y=2
so if we solve further we will not get the answer that is given in option
so option d is the write answer
Answer:
95.9 cm^2
Step-by-step explanation:
this figure is composed of two semicircles. the area of each semicircle would be determined and then added together.
area of a semicircle = 1/2 nr^2
r = radius
n = 22/7
bigger semicircle
1/2 x (22/7) x (6^2) = 56.57cm^2
smaller circle = 1/2 x (22/7) x (5^2) =39.29cm^2
Sum of the areas = 56.6 + 39.3 = 95.9 cm^2
the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero
Two possibilities:
28^2 + x^2 = 96^2
OR
28^2 + 96^2 = c^2
784 + x^2 = 9216
subtract 784 from both side
x^2 = 8432
Take the square root of both sides
x = 91.83 NOT an Integer
28^2 + 96^2 = c^2
784 + 8216 = c^2
10,000 = c^2
Take the square root of both sides
c = 100 HYPOTENUSE
Answer:
40.9 feet
Step-by-step explanation:
Rectangle area = length * width
A = l*w
w = 34.5 ft
A = 755 ft.
find diagonal length.
l = A/w = 755/34.5 = 21.884057 = 151/6.9 ft.
d = root ( w^2 + l^2) = root (34.5^2 + (151/6.9)^2 )
d = root( 1,190.25 + 478.91195)
d = 40.8553784 ft
