The sides of a triangle are in the ratio 10:6:24. The perimeter is 440 inches. What is the length of each side?
Answers
Answer:
one side = 110 inches
second side = 66 inches
third side = 264 inches
Step-by-step explanation:
10 + 6 + 24 = 40
one side of Δ = 10/40 x 440 = 110
second side of Δ = 6/40 x 440 = 66
third side of Δ = 24/40 x 440 = 264

Jenna earns $8 each week by completing chores. She already has $12 in her savings. How much will she have after 4 weeks?
y = 8x + 4
y = 8x
y = 8x + 12
Answers
Answer:
Option C is the correct answer.
Step-by-step explanation:
Per week earning = $8
Amount in savings = $12
y = Total amount
x = Number of weeks
y = 8x + 12
Where we can put x=4 to calculate earning of 4 weeks.
y = 8(4) + 12
y = 32 + 12 = $44
Therefore,
Option C is the correct answer.
The radius of a cylinder is increasing at a constant rate of 2 inches per minute. The volume remains a constant 440 cubic inches. At the instant when the radius of the cylinder is 44 inches, what is the rate of change of the height? The volume of a cylinder can be found with the equation V= [tex]\pi r^2h[/tex] Round your answer to three decimal places.
Answers
Answer:
The rate of change of the height is approximately [tex]-6.577\times 10^{-3}\,\frac{in}{min}[/tex].
Step-by-step explanation:
From Geometry we know that volume of cylinder ([tex]V[/tex]), measured in cubic inches, is expressed by:
[tex]V = \pi\cdot r^{2}\cdot h[/tex] (1)
Where:
[tex]r[/tex] - Radius, measured in inches.
[tex]h[/tex] - Height, measured in inches.
Given that volume remains constant, the expression for the rate of change of the height ([tex]\dot h[/tex]), measured in inches per minute, is:
[tex]2\pi\cdot r \cdot h \cdot \dot r + \pi \cdot r^{2}\cdot \dot h = 0[/tex]
[tex]2\cdot h\cdot \dot r + r\cdot \dot h = 0[/tex]
[tex]r\cdot \dot h = -2\cdot h \cdot \dot r[/tex]
[tex]\dot h = -\frac{2\cdot h\cdot \dot r}{r}[/tex]
[tex]\dot h = - \left(\frac{2\cdot \dot r}{r}\right)\cdot \left(\frac{V}{\pi\cdot r^{2}} \right)[/tex]
[tex]\dot h = -\frac{2\cdot \dot r \cdot V}{\pi\cdot r^{3}}[/tex] (2)
Where [tex]\dot r[/tex] is the rate of change of the radius, measured in inches per minute.
If we know that [tex]r = 44\,in[/tex], [tex]\dot r = 2\,\frac{in}{min}[/tex] and [tex]V = 440\,in^{3}[/tex], then the rate of change of the height is:
[tex]\dot h = - \frac{2\cdot \left(2\,\frac{in}{min} \right)\cdot \left(440\,in^{3}\right)}{\pi\cdot (44\,in)^{3}}[/tex]
[tex]\dot h \approx -6.577\times 10^{-3}\,\frac{in}{min}[/tex]
The rate of change of the height is approximately [tex]-6.577\times 10^{-3}\,\frac{in}{min}[/tex].

No
Step-by-step explanation:
1 is a prime number
0 is the only number that is neither prime or composite
Hello there!
No, 1 is not the only number that is neither prime nor composite.
0 is neither prime not composite because it has infinite factors. Composite numbers have more than 2 factors, but they must have a finite amount o factors. Since 0 has infinite factors, then it's neither prime nor composite.

Find the radius, and the approximate circumference and area of the circle below. (Use 3 for \pi)
Answers
(Pi value = 3)
Given diameter of circle = 12 inches
Radius of circle :
[tex] = \tt\frac{diameter}{2} [/tex]
[tex] = \tt\frac{12}{2} [/tex]
[tex] = \tt6 \: inches[/tex]
Thus, the radius of this circle = 6 inches
Circumference of this circle :
[tex] = \tt2\pi r[/tex]
[tex] =\tt 2 \times 3 \times 6[/tex]
[tex] = \tt36 \: inches[/tex]
Thus, the circumference of this circle = 36 inches
The area of this circle :
[tex] = \tt\pi {r}^{2} [/tex]
[tex] =\tt 3 \times 6 \times 6[/tex]
[tex] = \tt108 \: {inches}^{2} [/tex]
Thus, the area of this circle = 108 inches²
Therefore,Radius = 6 inchesDiameter = 12 inchesCircumference = 36 inches Area = 108 inches²Why can't we rewrite the math sentence 4+4+4+4+4+4 with an exponent?

Mrs.Giblin begins hiking at mile marker 25 on the Appalachian Trail and hikes 3 miles every hour. What is the slope?
Answers
Answer:
3 miles
Step-by-step explanation:
Slope is simply the change in position per unit rate. We could conclude that the steepness of the Applachian is the rate of change in position per unit time. Since the distance hiked on the Applachian is said to be 3 miles per hour, then we can conclude that the slope of the applachian is 3 miles
This is the change in miles / change in time.
Chang in miles = 3
Change in time = 1
Slope = 3/1
Slope = 3
