Each cube inside the rectangular prism has no edge length of 3/4 inch what is the volume of the rectangular

Answers

Answer: Volume = 81 cubic inches

Step-by-step explanation:

Given that each cube has length = 3/4 inches

The height H = 3/4 × 8 = 6 inches

Where 8 = number of cubes

The length L = 3/4 × 6 = 4.5 inches

Where 6 = number of cubes

The width W = 3/4 × 4 = 3 inches

Where 3 = number of cubes

The volume V = L × W × H

Substitute all the parameters into the formula

V = 4.5 × 3 × 6 = 81 cubic inches

Therefore, the volume of the rectangular prism is 81 cubic inches

Answer:

Answer: Volume = 81 cubic inches

Step-by-step explanation:

Given that each cube has length = 3/4 inches

The height H = 3/4 × 8 = 6 inches

Where 8 = number of cubes

The length L = 3/4 × 6 = 4.5 inches

Where 6 = number of cubes

The width W = 3/4 × 4 = 3 inches

Where 3 = number of cubes

The volume V = L × W × H

Substitute all the parameters into the formula

V = 4.5 × 3 × 6 = 81 cubic inches

Therefore, the volume of the rectangular prism is 81 cubic inches

Jim is paid $275 per week plus 2.5 % of his totals sales in dollars, x, which can be represented by j(x) = 275 + 0.025 x . Determine the value of x, in dollars, that will make their weekly pay the same.

Answers

Answer:

X = 18 000

Step-by-step explanation:

185 + 0.03x = 275 + 0.025x

Subtract 0.025x from both sides

185 + 0.005x = 275

Subtract 185 from both sides

0.005x/0.005 = 90/0.005

X = 18 000

Verify by replacing x with 18 000

185 + 0.03(18000) = 275 + 0.025(18000)

185 + 540 = 275 + 450

Answer:

(8,1) (15,2) (22,3) (29,4) (36,5) (43,6)

Step-by-step explanation:

Answer:

Step-by-step explanation:

The equation y=7x+1 is written in slope intercept form. That would be:

y=mx+b

m is the slope

b is the y intercept, or where the line first is seen on the y axis.

Because b=1, the y intercept is 1.

Because m=7, the slope is 7.

STEP 1: GRAPH THE Y INTERCEPT.

Since b=1, the line crosses the y intercept when y=1. So graph y=1 on the coordinate plane.

STEP 2: GRAPH THE SLOPE

Do this by going up 7, then right 1. Because 7 is a positive number, you go up.

What is the number that has a value 10 times the value of 0.009? Please Explain.

Answers

Answer:

Step-by-step explanation:

I don’t know

Answer:

0.09

Step-by-step explanation:

From what I'm understanding you have to use powers of 10. Here's how they work:

All you do is move the decimal point, I know that may sound weird but let me explain.

When we are working with powers of 10 you just multiply the number by 10.

10 x 0.009

Now instead of having to type that into a calculator, or working it out, you can just move the decimal point to the right or the left.

Here's how I remember it:

Multiplying- move it to the right so the number can get bigger

Dividing- move it to the left so the number gets smaller

The number of zeros (0) you have after the one determines how many times you move the decimal point.

100- move the decimal point twice

100000- move the decimal point 5 times

In this case you are multiplying and moving the decimal point to the right once. There is one zero in the number and the problem asks you to multiply.

0.009

= 0.09

You move the decimal point over once.

Hope this helps!!!

A sailboat and catamaran are in a race to see who can sail across the Atlantic ocean the fastest..

.The sailboat covers a distance of 3240 miles in 8 days
.The catamaran covered a distance of 4020 miles in 10 days
If the sailboat is able to maintain a constant rate for 10 days, how many more miles would they have traveled than the catamaran?

Answers

Answer:

The sailboat would cover 30 more miles than the catamaran.

Step-by-step explanation:

To find how many miles the sailboat goes in 1 day (unit rate) you divide 3240/8 that gives you 405 miles in one day. Multiply that by 2 to get 810 miles in two days. Add 810+3240=4050. That shows that in 10 days the sailboat would travel 4,050 miles which is 30 miles more than the catamaran.

Find the surface area of the triangular prism (above) using its net (below).

Find the surface area of the triangular prism (above) using its net (below).

Answers

This is quite simple, first, you must find the area of each shape, since the form of the prism is currently 2D.

Formula for (Area of Rectangle)= length x width

Formula for (Area of Triangle)= 1/2 base x height

Now, we have the formulas. Let’s get started!

(Identification) There are 3 rectangles and 2 triangles. 2 rectangles are of the same size and 2 triangles are of the same size.

Triangles~ the base is 6 and the height is 4.

1/2 (6 x 4) = 12

However, there’s two triangles. (of the same size)

12 x 2 = 24

Rectangles 1 and 2~ the length is 5 and the width is 7

5 x 7 = 35

However, there’s two rectangles. (of the same size)

35 x 2 = 70

Rectangle 3~ the length is 6 and the width is 7

6 x 7 = 42

There’s only one of these.

Now we add all the areas of the shapes together!

24 + 70 + 42 = 136

The surface area is 136.

if you rolled two dice what is the probability that you would roll a sum of 10

Answers

The probability of rolling a sum of 10 with two dice is 1/12.

What is probability?

Probability is a measure of the likelihood of an event to occur. Many events cannot be predicted with total certainty. We can predict only the chance of an event to occur i.e., how likely they are going to happen, using it.

Given that two dice are rolled and find the probability of a sum of 10.

The sample space of the event of rolling two dice is

S = {(1, 1), (1, 2), (1, 3), (1, 4), (1, 5), (1, 6),

      (2, 1), (2, 2), (2, 3), (2, 4), (2, 5), (2, 6),

      (3, 1), (3, 2), (3, 3), (3, 4), (3, 5), (3, 6),

      (4, 1), (4, 2), (4, 3), (4, 4), (4, 5), (4, 6),

      (5, 1), (5, 2), (5, 3), (5, 4), (5, 5), (5, 6),

      (6, 1), (6, 2), (6, 3), (6, 4), (6, 5), (6, 6)}

The total possible outcomes is 36.

The favorable outcomes that is the outcomes where the sum is 10 is

(1, 4), (2, 3), (3, 2).

The number of favorable outcomes are 3.

To find the probability of rolling a sum of 10 with two dice, write the sample space and then determine the number of favorable outcomes that is the outcomes where the sum is 10 and the total number of possible outcomes.

The formula to find out the probability of any event is:

\(\text{P(event)} = \dfrac{(\text{number of favorable outcomes})}{\text{total number of possible outcomes}}\)

By using the data and formula, the probability of rolling a sum of 10 is,

\(\text{P(event)} = \dfrac{(\text{number of favorable outcomes})}{\text{total number of possible outcomes}}\)

\(\text{P(rolling a sum of 10)} = \dfrac{3}{36}\)

On dividing both numerator and denominator by 3 gives,

\(\text{P(rolling a sum of 10)} = \dfrac{1}{12}\)

Hence, the required probability of rolling a sum of 10 with two dice is 1/12.

https://brainly.com/question/31828911

The probability that you would roll a sum of 10 if you rolled two dice is 1/12.

We need to consider all the possible outcomes and count the favorable outcomes to determine the probability of rolling a sum of 10 when rolling two dice.

When rolling two dice, each die has six possible outcomes, ranging from 1 to 6. To find the total number of outcomes, we multiply the number of outcomes for each die: 6 * 6 = 36.

Next, we need to count the number of favorable outcomes, which are the combinations of two dice that result in a sum of 10. These combinations include:

1. Rolling a 4 on the first die and a 6 on the second die: (4, 6)

2. Rolling a 5 on the first die and a 5 on the second die: (5, 5)

3. Rolling a 6 on the first die and a 4 on the second die: (6, 4)

There are three favorable outcomes.

Therefore, the probability of rolling a sum of 10 when rolling two dice is:

Probability = (Number of favorable outcomes) / (Number of total outcomes) = 3/36 = 1/12.

Hence, the probability is 1/12.
