Answer:
<h2>312.7 in^2</h2>
Step-by-step explanation:
This problem is on the mensuration of flat shapes, sectors and arc.
we know that the area of a sector is given as
A=(∅/360)*πr^2
Given that the length of the wiper R=24 in
and the length of the blade r= 16in
To find the area of the wiped surface we only require the length of the blade as the radius
The area of the wiped surface is given as= (140/360)*3.142*16^2
A= 0.3888*3.142*256
A=312.7 in^2
Answer:
Common difference is 55
Step-by-step explanation:
C(m)=55m
Substitute m=1 to find the distance traveled by Mia in one hour
55m= 55(1)
= 55
Distance traveled in one hour is 55 miles. Substitute m=2 to find the distance traveled by Mia in 2 hours
55m=55(2)
= 110
Distance traveled in 2 hours is 110 miles. Substitute m=3 to find the distance traveled by Mia in 3 hours
55m=55(3)
= 165
Distance traveled in 3 hours is 165 miles. Substitute m=4 to find the distance traveled by Mia in 4 hours
55m=55(4)
= 220
Distance traveled in 4 hours is 220 miles. Then the common difference is
d=110-55=165-110=220-165=55
Seven huge boxes and two tiny boxes total were bought by the contractor.
A linear equation is defined as an algebraic equation of maximum degree 1 is a linear equation.
According to the question, a builder needs to purchase nails to construct a house.
Both small and large boxes of nails are provided. There are 50 nails in each small box and 350 in each large box.
The contractor purchased 5 more large than tiny boxes, hence it is assumed that he purchased a certain number of little boxes.
He purchased (x+5) huge cartons.
So, 50(x) + 350(x+5) = 2590.
50x + 350x + 1750 = 2590.
400x = 2590 - 1750.
400x = 840.
x = 2.1
The bulk of the boxes he bought is 7.
