Shelley's kitten weights 2 1/3 times as much as she did last year. She now weighs 21 ounces. What did the kitten weight a year ago?
Answer:
weight of the kitten last year = 9 ounces
Step-by-step explanation:
Let
x = weight of the kitten last year
Weight of the kitten this year = 2 1/3 * x = 21
7/3*x = 21
7/3x = 21
x = 21 ÷ 7/3
x = 21 × 3/7
= 63/7
x = 9 ounces
weight of the kitten last year = 9 ounces

Answer:
$49425.1688842
Step-by-step explanation:
Use formula: v=c*(p^t), where v is the price now, c is the cost price, p is the 100-the depreciation percentage and t is the time/years passed)
0.9¹²(175000)
0.28242953648(175000)

A giant scoop , operated by a crane is in shape of a hemisphere of a radius 15 inches. The scoop if filled with molten steel. The steel is then poured into a cylindrical storage tank with a diameter of 16 inches how high will the molten steel rise
The hemisphere of radius 24 inches is full so the volume is 4/3 π 243 cubic inches. The cylinder has radius 16 inches so is volume is π 162 h cu inches. Thus pi 162 h = 4/3 π 243. Solve for h.

A town has an annual growth rate of 2%. In 1970, the population was 250 people. What was its population in 2020?
Answer:
In 2020 the population would be 673.
Step-by-step explanation:
Giving the following information:
Current population (PV)= 250
Growth rate (g)= 2% annualy
Number of periods (n)= 2020 - 1970= 50 years
To calculate the number of people in 2020, we need to use the following formula:
FV= PV*(1+g)^n
FV= 250*(1.02^50)
FV= 672.89 = 673

The area of a trapezium is 847 cm2. If the ratio of parallel sides is 9:2 and the
distance between them is 14 cm, find the length of parallel sides
Answer:
Area of trapezium = 1/2 x sum of parallel sides x height
1/2 x (9x + 2x) x 14 = 184
11x x 7 = 184
11x = 184/7
11x = 26.28
x = 26.28/11
x= 2.38

Answer:
Each game cost £3.75
Step-by-step explanation:
£13.75-£2.50=£11.25
£11.25÷3=£3.75
Answer:
Activity 1: 3g + 2.50 = 13.75
Activity 2: 3.75
Step-by-step explanation:
3g is because he played 3 games. You add 2.50 because that is also what Giovanni spent on. Equals 13.75 is because that's the total he payed.
To solve, first do - 2.50 from both sides. The new equation is 3g = 11.25. Now divide 3 from both sides to find g. g = 3.75. "g" is the cost of each bowling game. So the price of each bowling game is 3.75.

Crazy Al is making apple pie. His recipe calls for 6 apples to every 1/4 cup of sugar. He want to use up all his sugar to make his pie. He has 1 3/4 cups of sugar, how many apples does he need to make his pie?
Answer:
42 apples
Step-by-step explanation:
Crazy Al is making apple pie. His recipe calls for 6 apples to every 1/4 cup of sugar. He want to use up all his sugar to make his pie. He has 1 3/4 cups of sugar, how many apples does he need to make his pie?
From the question, we know that:
1/4 cup of sugar = 6 apples
1 3/4 cups of sugar = x
Cross Multiply
1/4 × x = 1 3/4 × 6
x = 1 3/4 × 6/1/4
x = 7/4 × 6/ 1/4
x = 42/4 ÷ 1/4
x = 42/4 × 4/1
x = 42 apples

Dan was thinking of a number. Dan subtracts 2.6 from the number and gets an answer of 72.8. Form an equation with
x
from the information.
Answer: x - 2.6 = 72.8
x is the number which Dan was thinking (x > 2.6)
we have:
x - 2.6 = 72.8
Step-by-step explanation:
2x +3y = 9
-3x +3y = -6
Rewrite the second equation:
This is to make the calculation easier. There are other ways to do this as well.
3y = 3x - 6
Substitute that into the first equation:
Since they are the same thing (=), it is possible to replace 3y.
2x + (3x - 6) = 9
Solve the equation:
2x + 3x = 9 + 6
5x = 15
x = 3
Substitute x = 3 into the first equation:
2(3) + 3y = 9
6 + 3y = 9
3y = 3
y = 1
Answer: x = 3, y = 1
Choose the polynomial that is written in standard form.
a. x + 4x5 + 10x3
b. x4 + 4x2 + 8x
c. −9x4 + 4x6 + 10x2
d. x4 + 4x4 + x6
Answer:
b. x^4 + 4x^2 + 8x
Step-by-step explanation:
I took the test. Also the exponents need to be in descending order in order for the equation to be in standard form.
So b, starts with an exponent of 4, the decreased to just the x variable with an understood exponent.
Decreasing -> 4,2,(1)
