Determine whether the solids are similar.

Two rectangular prisms are shown. The length, width, and height of the larger rectangular prism are 4 inches, 2 inches, and 4 inches respectively. The length, width, and height of the smaller rectangular prism are 2 inches, 1 inch, and 4 inches respectively.

The solids___similar.

Answer:

A=25

Step-by-step explanation:

Triangle area formula: A= base x height/2

Base:12-2=10

Height:9-4=5

(10x5)/2=25

So it's 25.

Answer:

a: y=70x

b: y=70x+100

c: They are parallel to each other, with equation b's line being 100 dollars above equation a.

Step-by-step explanation:

They both have the same slope (70), but new customers will have a y intercept of 100 because of the one-time fee.

Don't forget to like and rate!

The equation is given by y = 70x and for the new customers it is given by y = 70x + 100.

A linear equation is of the form:

y = mx + b

where y, x are variables, m is the slope of the line and b is the y intercept

Let x represent the number of months of service, and y represent the total amount  

a) A cable company charges $70 per month, hence:

y = 70x

b) The is an additional one-time $100 service fee, hence:

y = 70x + 100

Hence the equation is given by y = 70x and for the new customers it is given by y = 70x + 100

Answer:

1. $60

2. $80

3. $78

Step-by-step explanation:

1. 30 divided by 3 times 10 is 100. 18 divided by 3 times 10 is 60. Therefore if 30% of the budget is $18, 100% is $60.

2. 75 divided by 3 times 4 is 100. 60 divided by 3 times 4 is 80. In total, Annie and Ernie raised $80.

3. 100 divided by 10 times 6 is 60. 130 divided by 10 times 6 is 78. Karen spent $78 on shoes

Step-by-step explanation:

the absolute value of -9 is 9 because you take away the negative. so you would add them like normal and 9+12 is 21

Answer:

(d ) is the answer

I am sure

Step-by-step explanation:

Hey there!

Your answer is Option D.

Reason:

Product of 2and 9 = 2(9)

Product of 4 and 7 = 4(7)

Now; their sum = 2(9) + 4(7)

Therefore, your answer is Option D.

Add commeAnswer:

y = -4x

When x = 4, y = -16

When y = 20, x = -5

Step-by-step explanation:

First off, definitions: Direct variations refers to two variables being related with neither being the denominator of a fraction. (nothing along the lines of y = 1/x)

So, given that, I simply found what the ratio was between the two values. Something like buying gas at the gas station. The ratio between the gas you get and the money you pay is the price per gallon of gas. In this case, the proportion is -4 (-16 divided by 4).

Thus we have a relationship. For each y, you have negative four x's. Thus, y = -4x.

Finding the value of x when y = 20 simply requires plugging values in. Remember, a fundamental principle in all of Algebra is substitution. If two things are equal, they are interchangeable. So, if you saw "3 + 4" in a mathematical expression, you could simply erase it and write 7, so long as no other mathematical rules (multiplication before addition, for instance) interferes.

Thus, if y = 20, we can take our original equation and replace y with 20.

y = -4x       =>     20 = -4x

Then, simply solve for x, keeping in mind that when two items in math are written against each other, it means multiplication. Thus, we reverse the multiplication to division and divide both sides of the equation by -4.

20 / -4 = -5

Answer:8

Step-by-step explanation:16

Answer: A: y-x = -4

Step-by-step explanation:

To have an infinite number of solutions, two linear equations must be on top of each other, (so they intersect at every point). What this question is really asking is the equation for the plotted line!

This is simple enough:

two points are given, so lets fine the slope:

Slope = (y2-y1)/(x2-x1) = (-4 -0)/(0-4) = -4/-4 = 1

the slope is 1:

putting this into slope intercept form, we have y = x + b.

since b is the y intercept, and that is already given as -4, our completed equation is:

y = x - 4

which can be rewritten as y - x = -4

So your answer is the first option.

The required four points are (-5,-1), (1,-1), (-2,-4) and (-2, 2), which are 3 units away from the point P(-2,-1).

A surface with two dimensions known as the coordinate plane is created by two number lines. The x-axis is a single number line that runs horizontally. The y-axis is a vertical number line, which is the other number line.

In the given plane,

Coordinate of point P is (-2,-1)

The four points that are 3 units away from the point P(-2, -1) can be,

(-5,-1), (1,-1), (-2,-4), (-2, 2)

Answer:

Step-by-step explanation:

Answer:

The answer is C

Step-by-step explanation:

Use the Point-Slope Equation by doing y2-y1/x2-x1

Let say that 10 is x2 and 16 is y2. We can also say that -5 is x1 and -2 is y1.

Now Subtract 16 by -2

Do the same with 10 and 2.

We should get y=6/5x+b

We are halfway through now. We have to find the Y intercept.

let's replace x,y with -5,-2 which were one of the points.

-2=6/5(-5)+b

Once we simplify, we get y=4

Therefore, the answer is y=6/5x+4, or C

Step-by-step explanation:

Answer:

  6) 52%

  7) 38%

  8) 10%

Step-by-step explanation:

You want various probabilities based on the survey results shown in the table.

The total number of female responses is 12 +32 +8 = 52 out of the 100 surveyed.

The probability a girl was chosen is 52%.

The number of respondents who chose to fly was 26+12 = 38 of the 100 surveyed.

The probability the person chose to fly was 38%.

The number of males who chose "Other" was 10 out of the 100 surveyed.

The probability the person was a male who chose Other was 10%.

__

Additional comment

The questions ask about the probability that such and such was chosen. The table only reflects the probability given that the person chosen was among those surveyed. There is actually no way to answer the question asked based on the table data given.

Answer:

Both should be 1/6 considering the Sample Space I've drawn above.

Answer:

81/450 or 18%

Step-by-step explanation:

Since you are trying to get the probability model for the chance silver will be selected, you add up 81,117 and 252. This gets you 450denominator and since you are trying to find the probability for sliver, you put 81 in the numerator. This gets the you fraction 81/450. If you divide it, you get 0.18. Now if you are trying to make a decimal into a percent, you move the decimal point two spots to the right. So, 0.18 becomes 18%.
