Answer:
153.94
Step-by-step explanation:
c=2r*r
The radius is half of the diameter.
To find the radius you will divide 49 inches by 2.
You should get a total of 24.5
Now that you have your radius you are going to use the circumference formula to solve.
C= 2r*r
C=2(24.5)*(24.5)
type that into the calculator (without the parenthesis) and boom your done!
You answer should be 153.938
then you round to get a total of 153.94
I hope i was able to help!
Answer: c = 3771.481981 (decimal place) or 1200.5[tex]\pi[/tex] (exact form)
Step-by-step explanation:
c = 2[tex]\pi[/tex]r
c = 2 x [tex]\pi[/tex] x [tex]24.5^{2}[/tex]
radius = diameter divided by 2
= 49 divided by 2
= 24.5
c = 3771.481981 (decimal place) or 1200.5[tex]\pi[/tex] (exact form)

Answer:
B. 3
Step-by-step explanation:
If you were to multiply the top equation by 3 then the x value for the first equation would be 6 and since the bottom equation's x value is -6, if you were to add them, they would cancel eachother off.

Answer:
Step-by-step explanation:
x/13=10
We have to get rid of the 13. (the denominator)
How?
By multiplying 2 sides by 13
Remember the Rules of Maths:
1. Whatever you do to one side, you must do to the other.
2. Use the opposite operation.
So, we used Rule 2 to get rid of the 13.
Now:
x=10*13
(On the left side, the 13s cancel)
x=130
It is always a great idea to double-check
Does 130 divided by 13 equal 10?
Of course it does!
Have a great day!!
I hope everything is clear!

find the midpoint between two points on a coordinate plane whose coordinates are (5,7) and (-3,1)
Step-by-step explanation:
Mid point formula ,
x = (x1+x2)/2 , y = (y1+y2)/2
x = 1 , y = 4
therefore ,midpoint is (x, y)= (1,4)
(1,4) all u gotta do is 5+-3 ÷2 to find x and 7+1÷2 to find y and booom u got your answer

Triangle DEF has coordinates D(3, 4), E(4, 1), and F(1, -2). If the triangle is
dilated by a scale factor of 4, what are the coordinates of E?
Answer:
Hello! answer: coordinates of E' are (16, 4)
Step-by-step explanation:
4 × 4 = 16 4 × 1 = 4 therefore the new coordinates are (16, 4)
The coordinate of E after dilation is (16, 4).
What is a triangle?It is a two dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.
We have,
Triangle DEF has coordinates:
D = (3, 4)
E (4, 1)
F = (1, -2)
The coordinates are dilated with a scale factor of 4.
This means,
Multiply all the coordinates by 4.
Now,
D = (3 x 4, 4 x 4) = (12, 16)
E (4 x 4, 1 x 4) = (16, 4)
F = (1 x 4, -2 x 4) = (4 , -8)
Thus,
The coordinate of E is (16, 4).

Look at the pentagonal numbers. Use finite differences to determine which function represents the pattern.
f(x) = 1.5x - 0.5x
f(x) = 1.5x^2 + 1.5x
f(x) = 1.5x^2 - 0.5v
f(x) = 0.5x^2 + 0.5x
Answer:
f(x) = 1.5x - 0.5x
Step-by-step explanation:
The function of the pattern represented by the pentagonal numbers is the sum of three triangular numbers.
The triangular number general formula
x (x + 1) / 2
For example,
The sequence

Triangle 1 and 3 (they are triangles one unit smaller than 2)

Replacing n

(x-1) (x) / 2
(x-1) x / 2

Function represents the pattern
Triangle 2 + (Triangle 1 + Triangle 3)
Triangle 1 = Triangle 3
So then,

Fred paints houses. He was paid 475 dollars for a job that took 19 hours. His second job took 26 hours and he was paid 720. He was paid 1180 for his 3rd job. How long did this job take?
Answer:
Total time taken to complete the job is 26 hours
Step-by-step explanation:
Fred's First Job
Total amount paid = 475 dollar
Total hours of work = 19 hours
Charge per hour = 475/19 = 25 dollars per hour
Fred's second job
Total amount paid = 720 dollar
Total hours of work = 26 hours
Charge per hour = 720/26 = 27.69 dollars per hour
Fred's third job
Amount paid = 1180
When amount paid was 720, charge per hour was 27.69
When amount paid is 1180, charge per hour is (27.69/720) * 1180 = 45.38
Total time taken to complete the job = 1180/45.38 = 26 hours

Answer:
1) 5 : 7 : 8.75
2) Happy = 168 . Juma = 210
3) Rima = 17800 . Happy = 24920 . Juma = 31150
Step-by-step explanation:
1) 5 : 7 : 8.75
Ratio Rima to Happy = 5:7
Ratio Happy to Juma = 4:5
7/4 = 1.75
1.75 x 5 = 8.75
Ratio = 5 : 7 : 8.75
2) Happy = 168 . Juma = 210
Ratio = 5 : 7 : 8.5
120 / 5 = 24
Happy = 24 x 7 = 168
Juma = 24 x 8.75 = 210
3)17800 : 24920 : 31150
5 + 7 + 8.75 = 20.75
73870 / 20.75 = 3560
3560 * 5 = 17800 = Rima
3560 * 7 = 24920 = Happy
3560 * 8.75 = 31150 = Juma

Step-by-step explanation:
Perimeter= 2l+2w =2( l+w)
Let the width be =x
And Length=x+5
So that the Perimeter =2l+2w becomes
Perimeter =2x +2(x+5)
Perimeter =2x+2x+10

Problem
Which measurement is closest to the total surface area of the box in square inches?
A
603.19 in 2
B
1,507.96 in.

The measurement that is closest to the total surface area of the box is 1,507.96 [tex]in^2[/tex].
Step-by-step explanation:
The surface area of the cylinder can be found by adding the area of the two bases and the side, which is [tex]12^2\pi *2+ 24\pi *8 = 144\pi * 2+192\pi = 288\pi + 192\pi = 480\pi[/tex] ≈ 1507.96, so the correct answer is choice B.
