A rectangular pyramid and a rectangular prism have the same length, width, and height. If the volume of the rectangular pyramid is 75 cubic centimeters, what is the volume of the rectangular prism in cubic centimeters?
Answers
Answer:
225 cubic centimeters
Step-by-step explanation:
The formula for the volume of a rectangular pyramid is V = (1/3)Bh, where B is the area of the base and h is the height. The base of the rectangular pyramid is a rectangle with the same length and width as the rectangular prism. Let's call the length, width, and height of both shapes "l", "w", and "h", respectively. Then:
V_pyramid = (1/3)B_pyramid * h
75 = (1/3)(lw) * h
We also know that the rectangular prism has the same length, width, and height as the rectangular pyramid, so its volume can be calculated using the formula V_prism = lwh:
V_prism = lwh
V_prism = lwh = l * w * h
Since l = w = h in this case, we can simplify this to:
V_prism = l * w * h = l^3
We can use the equation for the volume of the rectangular pyramid to solve for h:
75 = (1/3)(lw) * h
225 = lw * h
h = 225/(lw)
Substituting this value for h into the equation for the volume of the rectangular prism gives:
V_prism = l^3 = l * w * (225/(lw))
V_prism = 225 cubic centimeters
Therefore, the volume of the rectangular prism is 225 cubic centimeters.

Point B has coordinates (4,1). The x-coordinate of point A is -2. The distance between point A and point B is 10 units. What are the possible coordinates of point A?
Answers
Answer: (-2, -7) or (-2, 9)
Step-by-step explanation:
distance = sqrt((x2 - x1)^2 + (y2 - y1)^2)
where (x1, y1) and (x2, y2) are the coordinates of the two points.
We know the coordinates of point B are (4, 1), and the x-coordinate of point A is -2. Let's assume the coordinates of point A are (x, y). Using the distance formula, we can write:
10 = sqrt((4 - (-2))^2 + (1 - y)^2)
Simplifying the equation, we get:
100 = (4 - (-2))^2 + (1 - y)^2
100 = 36 + (1 - y)^2
64 = (1 - y)^2
Taking the square root of both sides, we get:
8 = 1 - y or 8 = y - 1
Solving for y in each case, we get:
y = -7 or y = 9
Therefore, the POSSIBLE COORDINATES of POINT A: are (-2, -7) and (-2, 9).

For problems 1 – 4, convert to customary units. (3 points each)
Answers
The conversions are solved to obtain
1. 48,000 oz = 3000 lb
2. 4.5 T = 9000 lb
3. 7 gal = 56 pt.
4. 125 fl oz is equal to approximately 3.91 qt.
How to do the conversionsUsing unit conversion the following is done as follows
1.
1 lb = 16 oz
48,000 oz = x lb
hence x = 48000 / 16 = 3000 lb
2.
To convert from pounds (lb) to tons (T), we divide by 2000 (since 1 ton = 2000 lb). Therefore, T = 4.5 T * 2000 = 9000 lb
3.
To convert from gallons (gal) to pints (pt), we multiply by 8 (since 1 gal = 8 pt). Therefore, 7 gal = 7 * 8 = 56 pt.
4.
To convert from fluid ounces (fl oz) to quarts (qt), we need to divide by 32 (since 1 qt = 32 fl oz). Therefore:
125 fl oz = 125 / 32 qt
= 3.90625 qt (rounded to 5 decimal places)

A cardboard storage carton has a length of 3 feet, a width of 2 feet, and a volume of 12 ft³.whatis the minimum amount of cardboard needed to make the box? [hint: you're given volume, so find the missing height. then use your 3 dimensions to find the total surface area.]
Answers
Brainlist pls
Volume = Length x Width x Height
Substituting the given values, we get:
12 = 3 x 2 x Height
Solving for the height, we get:
Height = 12 ÷ (3 x 2) = 2 feet
Now, we can use the dimensions to find the total surface area of the box. The surface area of a rectangular box can be found using the formula:
Surface Area = 2lw + 2lh + 2wh
where l, w, and h are the length, width, and height of the box, respectively.
Substituting the given values, we get:
Surface Area = 2(3 x 2) + 2(3 x 2) + 2(2 x 2) = 12 + 12 + 8 = 32 square feet
Therefore, the minimum amount of cardboard needed to make the box is 32 square feet

Polygon ABCD with vertices at A(−4, 6), B(−2, 2), C(4, −2), and D(4, 4) is dilated using a scale factor of one eighth to create polygon A′B′C′D′. If the dilation is centered at the origin, determine the vertices of polygon A′B′C′D′.
Answers
Answer:
The third option
Step-by-step explanation:
Multiply all coordinates by 1/8 or 0.125
So
A(−4, 6) → A(-0.5, 0.75) when both points are multiplied by 0.125
B(−2, 2) → B(-0.25,0.25) when both points are multiplied by 0.125
We could go on and find all the values but the third option is the only one that has the right values so it has to be correct
Vertex A′: (x', y') = (kx, ky) = (1/8) * (-4,6) = (-1/2, 3/4)
Therefore, the coordinates of A′ are (-1/2, 3/4)
Vertex B′: (x', y') = (kx, ky) = (1/8) * (-2,2) = (-1/4, 1/4)
Therefore, the coordinates of B′ are (-1/4, 1/4)
Vertex C′: (x', y') = (kx, ky) = (1/8) * (4,-2) = (1/2, -1/4)
Therefore, the coordinates of C′ are (1/2, -1/4)
Vertex D′: (x', y') = (kx, ky) = (1/8) * (4,4) = (1/2, 1/2)
Therefore, the coordinates of D′ are (1/2, 1/2)
So, the vertices of dilated polygon A′B′C′D′ are (-1/2, 3/4), (-1/4, 1/4), (1/2, -1/4), and (1/2, 1/2).
Suppose you have $1500 and want to have $8000 in 15 years. What simple interest rate will you need? Please tell me
Answers
Answer: Rate = 0.289 or 28.9%
Step-by-step explanation:
To determine the simple interest rate required to turn $1500 into $8000 in 15 years, we can use the formula:
Simple Interest = Principal x Rate x Time
where:
Principal = $1500
Time = 15 years
Simple Interest = $8000 - $1500 = $6500
Substituting the given values, we have:
$6500 = $1500 x Rate x 15
Simplifying the equation:
Rate = $6500 / ($1500 x 15)
Rate = 0.289 or 28.9%
Therefore, a simple interest rate of 28.9% is required to turn $1500 into $8000 in 15 years. Note that this assumes that the interest is compounded annually. If the interest is compounded more frequently, a lower interest rate would be required to reach the same goal.
Money is put into two accounts. Account A earns 3.5% interest annually, and account B ears 2.6% interest annually. Assuming $20,000 is split evenly among the accounts and interest is not compounded, how much interest would be earned in total after 6 years?
Answers
Answer:
The total interest earned in both accounts after 6 years would be $2,100 + $1,560 = $3,660.
Step-by-step explanation:
After 6 years, the total interest earned on account A would be:
Interest = Principal x Rate x Time
Interest = $10,000 x 0.035 x 6
Interest = $2,100
The total interest earned on account B would be:
Interest = Principal x Rate x Time
Interest = $10,000 x 0.026 x 6
Interest = $1,560
Therefore, the total interest earned in both accounts after 6 years would be $2,100 + $1,560 = $3,660.

to solve how much ice there is you need to do 16 • .30, which would get you 4.8

A jacket has an original price of $50. You have a 20% off coupon. The sales tax will be 4%. What will you pay for the jacket after the discount and sales tax?
Answers
20% * $50 = $10
So the discounted price of the jacket is:
$50 - $10 = $40
Next, we need to calculate the sales tax on the discounted price. The sales tax is 4% of the discounted price of $40, which is:
4% * $40 = $1.60
Finally, we add the sales tax to the discounted price to get the total price:
$40 + $1.60 = $41.60
Therefore, you will pay $41.60 for the jacket after the discount and sales tax.
Answer:
$41.6
Step-by-step explanation:
The formula to find discount is (discount% x Original price) - original price.
In this case, that would be .20 times 50, which is 10.
Now you need to subtract 10 from 50, which is 40.
40 is the discounted price of the jacket before tax.
To find the tax price, you need to multiply the store price times the % tax, and add it to total cost.
In this case it would be 40 x .04, which is 1.6.
Now you add 1.6 to 40 which is $41.6.
Therefore, you will pay $41.6 for the jacket.
