Answer:
He cuts off a section representing a percent of the current area so that the remaining area represents the next term in the pattern, rounded to nearest whole centimeter. The area after each cut is shown on the graph.
Answer: 75 square
Explanation:
Width is X
Length is 3x
Every rectangle has 2 equal widths x 2 equal lengths
Perimeter is 2x + 2(3x) = 40
X = 5
Width is now 5in
Length is now 15in
Area is 75in^2
Half of a perimeter is length + width, which equals to 20in
4x = 20, CX = 5
= 75 sq

Answer:
y= 7
Step-by-step explanation:
Plug in values into y=mx+b
m= slope
b= y intercept
Since slope is 0, y will always be at 7.
y= 0(x) +7
y= 7
Answer:
5
Step-by-step explanation:
for the first gear
revolutions/teeth
1 / 24
2 / 48
3 / 72
4 / 96
5 / 120
6 / 144
for the second gear
revolutions/teeth
1 / 40
2 / 80
3 / 120
4 / 160
<em>the two marks will meet after 120 teeth, 5 revolutions of the first gear and 3 revolutions of the second.</em>
the way to get that amount of teeth is
the Least Common Multiple equals the product of all factors, but those factors who are repeted for both numbers should be only once.
120 teeth are 5 revolutions for gear1 and 3 por gear2
To solve this problem you must apply the fomrula for calculate the area of a cylinder, which is shown below:
A=2πrh+2πr^2
Where r is the radius and h is the height of the cylinder
You have that r=15.1 inches and h=12.8 inches, then:
A=2πrh+2r^2
A=2π(15.1 in)(12.8 in)+2π(15.1 in)^2
A=2647 in^2
The answer is 2647 in^2
