Step-by-step explanation:
Formula for volume of a circle: V=πr²
If you multiply the circle by height, it becomes a cylinder.
Formula for volume of a cylinder: V=πr²h
Plug in the numbers and get r by itself:
471 = πr²(6)
Divide both sides by 6:
78.5 = πr²
Divide both sides by π:
25 = r²
Square root both sides:
[tex]\sqrt{25}[/tex] = [tex]\sqrt{r} \\[/tex]²
5 = r

Write the equation for an exponential function that triples ever year, x, when the original amount is 4.
Answer:
y = 4(3)^x
Step-by-step explanation:
Here, we want to write the exponential equation
From the question, we have the equation tripling in x value every year and the original amount is 4
The exponential equation is of the form;
y = a(b)^n
In this case;
a = 4 , b = 3 and n = x
So we have the equation as;
y = 4(3)^x
Annabelle has 56 1 cm³ what are the dimensions of the rectangle Langer prism Annabelle could build with all the cubes
Answer:
The six possible rectangular prisms Anabelle could build are;
W = 1, B = 1, L = 56
W = 1, B = 2, L = 28
W = 1, B = 4, L = 14
W = 2, B = 2, L = 14
W = 1, B = 7, L = 8
W = 2, B = 4, L = 7
Step-by-step explanation:
The number 1 cm³ Annabelle has = 56
The dimensions volume of the cubes Annabelle could build with the 1 cm³ = 56 cm³
The volume of rectangular prism, V = L × B × W
∴ For the rectangular prism, V = 56 cm³ = L × B × W
Therefore, the possible dimensions of the prism are three factors of 56, including;
1, 2, 4, 7, 8, 14, 28, 56
The combination of 3 factors of 56 that can be multiplied together to give 56 and therefore, the possible rectangular prisms includes;
W × L × B = A
1) 1 × 1 × 56 = 56
2) 1 × 2 × 28 = 56
3) 1 × 4 × 14 = 56
4) 2 × 2 × 14 = 56
5) 1 × 7 × 8 = 56
6) 2 × 4 × 7 = 56
There are therefore 6 possible rectangular prisms Annabelle could build
Explain what the equation 3x = 6 means without using the word equal.
Explain why 2 is a solution of the equation
Step-by-step explanation:
1. 3 multiplied by x is the same value of 6
2. since 3x is on the left side we have to divide the equation by 3 on both sides which doesn't change the value of x, but it helps us get the value for x. so when you divide the equation by 3 the answer for x=6/2 which 2 divided by 6=3
Hope that helps :)

Which is more, 5 tons or 9,998 pounds?
Answer:
5 tons
Step-by-step explanation:
5 tons are more than 9,998 pounds.
What is ratio?Ratio essentially compares quantities, i.e., it displays the value of one quantity in relation to the other quantity.
The ratio of two values, a and b, will be a:b.
According to question,
We have to find which value is greater, 5 tons or 9,998.
Since,
1 ton = 2000 pounds
Therefore,
5 tons = 5 x 2000 pounds
5 tons = 10,000 pounds.
It implies that, 5 tons are more than 9,998 pounds.

Find the value of each variable in the parallelogram
Alright.
For 7, you'll want to put congruent sides equal to each other, assuming they are parallelograms. So, you'll get the two equations:
3x+2=23
2y-7=9
Solve using GEMDAS/PEMDAS, and you'll get these answers.
3x+2=23
3x=21
x=7
2y-7=9
2y=2
y=1
For 8, you'll want to do the exact same thing, formatting the numbers to equal each other. You'll get these two equations:
3y+5=14
2x-5=17
Solving them would make:
3y+5=14
3y=9
y=3
2x-5=17
2x=22
x=11
For 9, you have to remember that the angle opposite of one angle in a defined parallelogram are congruent. Thus:
130=2h
5k=50
solve them and you get
h=65
k=10
___________________________________________
Hope that helped. Good luck.
Answer:
7.) y=8, x=7
8.) y=3, x=11
9.) h=65, k=10
Step-by-step explanation:
First, let's start with #7. By definition of a parallelogram, we can say that opposite sides are congruent, meaning 2y-7=9 and 3x+2=23.
So, solving these problems-
2y-7=9
2y=16
y=8
3x+2=23
3x=21
x=7
Now, let's move on to #8. For this, a defining property of a parallelogram is that the diagonals bisect each other. So, 3y+5=14 and 2x-5=17.
Let's solve these equations-
3y+5=14
3y=9
y=3
2x-5=17
2x=22
x=11
Now, finally #9. Another defining property of a parallelogram is that opposite angles are congruent. So, 2h=130 and 5k=50.
So, h= 65 and k= 10.

Answer:
y = 25x + 128.8
Step-by-step explanation:
y = total cost
x = amount of days the car was rented
25 represents the daily charge for the fee and the insurance (15+10=25)
128.8 represent the cost for miles driven by Jerry
This was calculated by multiplying the amount of miles he drove (644) by the cost of each mile (.20)
644x.20=128.8 so the cost for miles driven is $128.8 which is why it was added to the equation
Verify that the segment lengths form a triangle. Is the triangle acute, right, or obtuse?
Answer:
The lengths do form a triangle and it is a right triangle.
Step-by-step explanation:
Part I:
To find out if 3 segment lengths form a triangle, you must verify that the sum of the two SMALLER sides (6+8) is GREATER than the longest side (10). That is true for this case. We have a triangle
Part II:
To find out the type of triangle, we must incorporate the Pythagorean theorem:
If [tex]c^2 = a^2 + b^2\\[/tex] then it is a right triangle. Substitute the values. (c=10, b=8, 6=a)[tex]10^2 = 6^2 + 8^2\\100 = 100[/tex]How meny cup of smoothies can you get with 3 quarts of orange juice,5 pints of milk and 5 cups of pineapple juice.
Answer:
27 cups
Step-by-step explanation:
Amount of orange juice in the mixture = 3 quarts
Therefore, number of cups of orange juice = 3 × 4 cups [Since, 1 quarts = 4 cups]
= 12 cups
Amount of milk in the mixture = 5 pints
Therefore, amount of milk in cups = 5 × 2 [Since, 1 pint = 2 cups]
= 10 cups
Amount of pineapple juice in the mixture = 5 cups
Amount of mixture = Amount of Orange juice + Amount of pineapple juice + Amount of milk
= 12 + 10 + 5
= 27 cups
Therefore, total amount of smoothies = 27 cups
A preschool has a student to teacher ratio of 5:2 The total number of students and teachers was 56 last year and is 70 this year How many students and teachers were there for each of the two years
Answer:
Step-by-step explanation:
Student : teacher = 5 : 2
Number of students = 5x
Number of teachers = 2x
Last year:
Last year Total = 56
5x+ 2x = 56
7x = 56
x = 56/7
x = 8
Number of students = 5*8 = 40
Number of teachers = 2*8 = 16
This year:Total = 70
5x + 2x = 70
7x = 70
x = 70/7
x = 10
Number of students = 5*10 = 50
Number of teachers = 2*10 = 20
