Work out the circumference of this circle.
Take it to be 3.142 and give your answer to 1 decimal place.
9m
Answer:
C = 28.278 m
Step-by-step explanation:
The attached figure shows a circle whose diameter is 9 m.
Radius = Diameter/2
r = 9/2 = 4.5 m
The circumferance of the circle is given by :
C = 2πr
Put r = 4.5 m in the above formula
C = 2 × 3.142 × 4.5
= 28.278 m
So, the circumference of this circle is 28.278 m.

Answer:
2 x 2 x 2 x 2 x 3 x 3
Step-by-step explanation:
Since 144 is an even number, we can first break it down like so:
144 = 72 x 2
Because 2 is a prime number.
We can further break it down like so:
144 = 36 x 2 x 2
144 = 18 x 2 x 2 x 2
144 = 9 x 2 x 2 x 2 x 2
144 = 3 x 3 x 2 x 2 x 2 x 2
Putting the numbers in order, 144 = 2 x 2 x 2 x 2 x 3 x 3

A ribbon is 5 2 5 yards long. Mae needs to cut the ribbon into pieces that are 2 5 of a yard long. How many pieces of ribbon can she cut?
Answer: The number of pieces of the ribbon she can cut = [tex]13\frac12[/tex] yards
Step-by-step explanation:
Given: The length of the ribbon = [tex]5\dfrac25[/tex] yards
[tex]= \dfrac{5\times5+2}{5} =\dfrac{27}{5}[/tex] yards
Length of each piece = [tex]\dfrac25[/tex] yards
The number of identical pieces can be cut from the entire ribbon = (Length of the ribbon ) ÷ (Length of each piece )
[tex]=\dfrac{27}{5}\div\dfrac{2}{5}\\\\=\dfrac{27}{5}\times\dfrac{5}{2}\\\\=\dfrac{27}{2}\\\\=13\dfrac12[/tex]
Hence, the number of pieces of the ribbon she can cut = [tex]13\frac12[/tex] yards

The length of Dwight's garden is 12.5 meters. Dwight measured it but made a measurement error of 6%. Find the lowest and highest measurement Dwight could have made. Show your work.
Answer: See Explanation
Step-by-step explanation:
From the question, The length of Dwight's garden is 12.5 meters but he measured it and made a measurement error of 6%.
The lowest measurement Dwight could have made will be:
= 12.5 - (6% × 12.5)
= 12.5 - (0.06 × 12.5)
= 12.5 - 0.75
= 11.75 meters
The lowest measurement Dwight could have made will be:
= 12.5 + (6% × 12.5)
= 12.5 + (0.06 × 12.5)
= 12.5 + 0.75
= 13.25 meters

Max was assigned to make 64 cookies for the bake sale. He made 125% of that number. 90% of the cookies he made were sold. How many of Max's cookies were left after the bake sale?
Answer: there are 8 cookies left
Step-by-step explanation:
Let's count how many cookies Max baked:
125% = 1.25
64 × 1.25 = 80
Let's count how many cookies were sold:
90% = 0.9
80 × 0.9 = 72
Leftover cookies:
80 - 72 = 8
Eric's mother drives to work in 20 minutes when driving at her usual speed. When traffic is bad,she drives 10 miles per hour slower, and the trip takes 10 minutes longer. What is Eric's mother's usual speed
Answer:
Pretty Sure it’s 20mph
Step-by-step explanation:
X/20=x-10/30
30x=20x-200

-20x
10x=-200
Divied by ten on both sides.
x=-20
20mph

(w-8)°
(2W-1)º
Answer:
63
Step-by-step explanation:
[tex](w - 8) \degree + (2w - 1) \degree = 180 \degree \\ (linear \: pair \: \angle s) \\ (w - 8 + 2w - 1) \degree = 180 \degree \\ \\ (3w - 9) \degree = 180 \degree \\ \\ 3w - 9 = 180 \\ \\ 3w = 180 + 9 \\ \\ 3w = 189 \\ \\ w = \frac{189}{3} \\ \\ w = 63[/tex]

Shay graphs an octagon in the coordinate plane. She then applies the transformation 4(x, y) to the octagon. Ned applies the transformation (x + 4, y + 4) to Shay’s original octagon. What is the difference in the images?
Answer:
The perimeter of Shay’s image is 4 times greater than the perimeter of Ned’s image.
Step-by-step explanation:
When Stacy does 4(x,y) it's a dilation so it increases by 4 times, while Ned's adds 4 to x and y, Stacy multiplies it.
