Answer:

  74 3/8 cubic feet

Step-by-step explanation:

The volume of the tub is the product of the dimensions:

  V = LWH

  = (5 ft)(3.5 ft)(4.25 ft)

  = 74.375 ft³

The tub can hold 74 3/8 cubic feet of water.

Answer:

5 in^2

Step-by-step explanation:

2x2 for the square = 4 in

1x2/2 for the triangle = 1 in

Answer:

so find the area of the swuare first. 2 times 2 = 4. then you have to add that to the area of the triangle which is 1/2 times base times height. We know that the height is 1 and the base is 2 (from the square's common side shared) so its gonna be 2 times 1 which is 2 divided by 2 which is one soo its 4+1=5

so the answer is 5 inches squared

Step-by-step explanation:

9514 1404 393

Answer:

  28.5 ft³

Step-by-step explanation:

The side length of the base is 1/4 of the perimeter, so is ...

  s = (10.1 ft)/4 = 2.525 ft

The area of the square base is the square of the side length, so is ...

  B = s² = (2.525 ft)² = 6.375625 ft²

The volume is given by ...

  V = 1/3Bh . . . . . where h is the height

  V = 1/3(6.375625 ft²)(13.4 ft) ≈ 28.4778 ft³

The volume of the pyramid is about 28.5 ft³.

Answer:

w= -9/8

Step-by-step explanation:

-1/3w -3/5 = 1/5w

+1/3w            +1/3 w

-3/5=1/5w+1/3w

Make common denominators to combine like terms of the right

-3/5=1/5w+1/3w

         *3       *5

-3/5=3/15w+5/15w

-3/5=8/15w

multiply both sides by the reciprocal of 8/15 which is 15/8

-3/5*15/8=8/15w*15/8

[tex]\frac{-3}{5}[/tex]*[tex]\frac{15}{8}[/tex] ----> cross reduce 5 in the denominator becomes 1 and 15 in the numerator becomes 3

[tex]\frac{-3}{1}[/tex]*[tex]\frac{3}{8}[/tex] -----> now multiply across

w= -9/8

Answer: -6/7

Step-by-step explanation:

-1/2w-3/5=1/5w

-w/2 - 3/5=w/5

Collect like terms

w/5 + w/2=-3/5

(2w + 5w)/10=-3/5

7w/10=-3/5

Cross multiply

7w x 5=-3 x 10

35w=-30

Divide both sides by 35

35w/35=-30/35

w=-6/7

Answer:

Yes

Step-by-step explanation:

Step-by-step explanation:

Each point moves to half its previous distance from P. It is probably easier to count grid squares on the graph than it is to do the math on the coordinates.

If you're doing the math on the coordinates, it is convenient to use P = (0, 0), then multiply each of the coordinates of A, B, and C by 1/2. For example:

  A' = (1/2)A = (1/2)(8, 4) = (4, 2)

Step-by-step explanation:

The correct rule for the transformation that translates triangle ABC into triangle A'B'C' is:

(x, y) → (x - 4, y + 2)

Here, we have,

In the transformation, the x-coordinates of the points are shifted 4 units to the right, which is represented by subtracting 4 from the original x-coordinate.

Similarly, the y-coordinates of the points are shifted 2 units up, which is represented by adding 2 to the original y-coordinate.

Therefore, the correct rule is (x, y) → (x - 4, y + 2).

Hence, The correct rule for the transformation that translates triangle ABC into triangle A'B'C' is:

(x, y) → (x - 4, y + 2)

Step-by-step explanation:

From the spinner there are 8 possible outcomes (1 to 8)

From the coin, there 2 (heads or tails)

8*2=16

There are 16 possible outcomes, when spinning a spinner numbered from 1 to 8 and tossing a coin.

Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

WE need to find the possible outcomes are there when spinning a spinner numbered from 1 to 8 and tossing a coin.

From the spinner, there are 8 possible outcomes (1 to 8)

From the coin, there 2 heads or tails;

8 x 2 = 16

Hence, There are 16 possible outcomes, when spinning a spinner numbered from 1 to 8 and tossing a coin.

Answer$5.22

Step-by-step explanation:

Answer:

B) 2

Step-by-step explanation:

We have to find the interval of time for which they begin the traject simultaneously.

One begins each 10 days, other each 12 and other each 15. So to find the number of days before dey start together, we have to find the lesser common multiple(non-zero) between 10,12, and 15.

M(10) = {0,10,20,30,40,50,60,...}

M(10) are the multiples of 10.

M(12) = {0,12,24,36,48,60,...}

M(15) = {0,15,30,45,60,...}

So the lesser common multiple between 10,12 and 15 is 60.

This means that they will begin together each 60 days.

So, first on March 14, after that:

60 days is approximately months.

So approxiately on May 14, and then approximately on July 14

That is, two times before July 31.

Step-by-step explanation:

Using a calculator or table:
