Gabriel has 15 ⅝ pounds of clay. He will use 7/10 pound to make each bowl. After making 8 bowls, Gabriel wonders how many more bowls he can make. How many more bowls can how make?
Answer:
14
Step-by-step explanation:
The total amount of bowls he can make given the pounds of clay and the pound needed to make a bowl = [tex]15\frac{5}{8}[/tex] ÷ [tex]\frac{7}{10}[/tex]
= [tex]\frac{125}{8}[/tex] ÷ [tex]\frac{7}{10}[/tex]
= [tex]\frac{125}{8}[/tex] ×[tex]\frac{10}{7}[/tex] = 22.32
Number of bowls he can more more = total amount of bowls that can be made - number of bowls already made
22.32 - 8 = 14.32 bowls
Rounding off to the nearest whole number gives 14

A parallelogram has an area of 20 square centimeters. The height of the triangle is 5 centimeters. What is the length of its base?
Answer:
4 cm
Step-by-step explanation:
A parallelogram area formula= Base x Height.
It already gave you the area so you can work backwards to solve for the base.
So, 20 divided by 5(the height) is 4.
Therefore, you can conclude that the length of the base is 4 cm.

You want to buy a new car. You can afford payments of $300 per month and can borrow the money at an interest rate of 5.2% compounded monthly for 5 years.
Answer:
$367.17
Step-by-step explanation:
we are find the cost of the car after 5 years
Using the compound interest formula;
A = P(1+r/n)^nt
Given
Principal P = $300
rate r = 5.2% = 0.052
Time t = 5years
Time of compounding n = 1/12 (monthly)
Substitute into the formula
A = 300(1+0.052(12))^5(1/12)
A = 300(1+0.624)^0.4167
A = 300(1.624)^0.4167
A = 300(1.2239)
A = 367.17
hence the amount of the car after 5years is $367.17

How do you find the circumference of a circle? Please include an example if you’d like.
Answer:
Step-by-step explanation:
Plug the given value of the diameter into the formula and solve.[2]
Example problem: You have a circle tub with a diameter of 8 feet, and you want to build a white fence that creates a 6-foot wide space around the tub. To find the circumference of the fence that has to be created, you should first find the diameter of the tub and the fence which will be 8 feet + 6 feet + 6 feet, which will account for the entire diameter of the tub and fence. The diameter is 8 + 6 + 6, or 20 feet. Now plug it into the formula, plug π into your calculator for its numerical value, and solve for the circumference:
C = πd
C = π x 20
C = 62.8 feet

I have to find the area of the shaded region in the figure above and answer using an exact and approximate answer
Answer:
3925 units²
Step-by-step explanation:
area of larger circle = πr² = (3.14)(250²) = 196,250
area of smaller circle = πr² = (3.14)(200²) = 125,600
area of full donut = 196,250 - 125,600 = 70,650
20/360 = 1/18 of full donut
1/18(70,650) = 3925 units²
