Answer: 6.9 and 10.4
Step-by-step explanation:
The perimeter of the pentagon is 10 so you can either do 10 times 1.38 times 1/2 or do 5 times 1.38 and it equals 6.9
The perimeter of the hexagon is 12 and you follow the same steps so I did 6 times 1.73 and you get 10.4
Answer:
$4.59
Step-by-step explanation:
At the sale price:
5 paints set cost Jasmine $16.45
Each paint set = Total cost of 5 paints set / 5
= $16.45 / 5
= $3.29
What was the price of 1 paint set before the sale?
Because the store reduces the price of each paint set by $1.30 before selling, we will add $1.30 to the price of each paint set during sales
Price of each paint set during sales = $3.29
price of 1 paint set before the sale = $3.29 + $1.30
= $4. 59
4$-20%
X$-100%
X=4·100:20=400:20=20
Answer : He paid for the meal 20$.
Answer:
this answer requires that you do a little solving to find all the dimensions we need for the volume.
We know that H (height) = 2m
Diameter = 5 x height, so
Diameter = 5 x 2m = 10m
If you have the formula for finding the volume of a cylinder, it is basically the area of the circular base x cylinder height. You may know already that the area of a circle is (pi) x radius2
So this will be 2 (the height) x (pi) x r2
As we just figured out, the DIAMETER is 10, so the radius is half the diameter = 5.
This brings our volume to 2 x (pi) x 52
= 2 x (pi) x 25
2x25 = 50, so we have 50 x (pi).
Pi = 3.14
50 x 3.14 = 157
And don't forget your units = 157 m3
Answer:
25°
Step-by-step explanation:
2x - 5° = x + 20°
2x - x = 20° + 5°
x = 25°
