Answer:
Step-by-step explanation:
Circumstance of a curcle C=2*pi*r
So if you want to find r from this equation you come up with r=C/2*pi. That's exactly what they give you in the problem.
Now you know that C= 26.69 so replacing what we know in the formula r=C/2*pi you get
r=26.69/2*3.14 =4.25
So looking at the figure you they said r=4.25
That means that the figure is has to be a circle.
Hope that makes sense.

Answer:
8: 73.2 cm
10: 738 mm
Step-by-step explanation:
8: A= 12.2 (4.5 + 7.5) / 2 --> 146.2 / 2 = 73.2 cm
10: A= 36 (22 + 19) / 2 --> 1,476 / 2 = 738 mm
Answer:
8: 73.2
10: 738
Step-by-step explanation:
Area of a trapezoid = [tex]A=\frac{a+b}{2} h[/tex]
where a and b = base lengths and h = height
For #8
These are the given dimensions
Base 1 = 4.5
Base 2 = 7.5
Height = 12.2
All we have to do is plug in the values into the formula
So....
[tex]A=\frac{4.5+7.5}{2} 12.2\\4.5+7.5=12\\\frac{12}{2} =6\\6*12.2=73.2[/tex]
Hence the answer is 73.2cm²
For #10
Once again all we have to do is plug in the values into the formula
[tex]A=\frac{22+19}{2} 36\\22+19=41\\\frac{41}{2} =20.5\\20.5*36=738[/tex]
Hence the answer is 738

Jasraj left his house and walked 1500 m east to the supermarket. He then walked another 500 m east to the comic store before walking back home the same way he came. How many kilometers did Jasraj walk altogether?
Answers
Answer:
Jasraj walked 4 kilometers all together
Step-by-step explanation:
First, add.
1,500 + 500 = 2,000
Then, multiply by 2.
2,000 × 2 = 4,000
Now, we have to convert to kilometers.
1 kilometer = 1000 meters
4,000 ÷ 1,000 = 4
So, Jasraj walked 4 kilometers!

Answer:
x = 5
Step-by-step explanation:
4x + 2y + z = 24
2x - 3y - z = 2
5x + y + 2z = 21
-----------------
Eliminate z
Add the 1st and 2nd eqn
4x + 2y + z = 24
2x - 3y - z = 2
----------------
6x - 1y = 26 eqn A
Multiply the 2nd eqn by 2, then add the 3rd.
4x - 6y -2z = 4
5x + y + 2z = 21
----------------
9x - 5y = 25 eqn B
---------------
Now you have 2 eqns in 2 unknowns, not 3.
Multiply eqn A by 5 and subtract eqn B.
30x - 5y = 130 eqn A times 5
9x - 5y = 25 eqn B
-------------
21x = 105
x = 5

x = 5 is the answer

NO LINKS PLEASEE!! IM BEGGING YOU NO LINKSS!!!
Answers
Answer:
A = (1/2)Pa = Pa/2
You can multiply both sides by 2 to eliminate the fraction on the right side:
2A = 2(Pa/2) = Pa
Then divide both sides by a (or multiply both sides by 1/a) to leave P alone on the right side:
(2A)(1/a) = 2A/a = (Pa)(1/a) = P
Rewriting:
P = 2A/a
You could also have divided by a first then multiplied by 2; which you should do first does not matter in this example.

The volume of a right rectangular prism is 70 7/8 cubic feet and its base is a square with a side length of 4 1/2 feet. what is the height?
Answers
Answer:
7/2 feet
Step-by-step explanation:
Volume of Right Rectangular Prism: V = w * h * l
You are given the volume, and the base (which would include l and w)- and are told to find h.
70 7/8 cubic feet = 4 1/2 feet * h * 4 1/2 feet (simplify the right side)
70 7/8 cubic feet = 81/4 feet squared * h (divide both sides by 81/4)
7/2 feet = h
The height will be 7/2

If 30% of a number equals 8, find 90% of that number.
Answers
Answer:
8.88
Step-by-step explanation:
I believe it is 8.88 becuase this question is asking to find 90% pf that number.
What do you need to do?
you have to make a proportion.
8/x 90/ 100
You would now cross multiply. 90* x = 90x 8*100= 800
the equation you would need is 90x = 800. divide them and you get 8.88.
ROUNDED: you get 9.

Answers
Answer:
Idc
Step-by-step explanation:
I don’t really wanna help, so thanks for the points! Don’t scroll down! I’m warning you!!!
Figure 1 and Figure 4 have the same areas because the area of a parallelogram is just length times width.
Figure 1: 15×4=60 cm
Figure 2: 18×3=54 cm
Figure 3: 11×6=66 cm
Figure 4: 12×5=60 cm
As you can see, figure 1 and figure 4 have the same areas. So, C is the correct answer.

From question:
Susan has a box of nails that has the same proportion of small, medium, and large nails as John's box =Meaning same ratio
John ratio. Susan
s : m : L s : m : L
65 : 40 : 45. 13 : 8 : 9
13 : 8 : 9. x : 176 : y
x = (176/8)*13
=286
y = (176/8) * 9
= 198
Total number of nails in Susan box
= x + 176 + y
= 286 + 176 + 198
=660
