Answer:

-5+15 is 10

Step-by-step explanation: what you could've done was 15-5 and it would've brang the same answer.

V Sphere = 4/3 x pi x r³

d = 42 cm so r (radius) = 21 cm

then

V ≈ 4/3 x 3,14 x 21³ ≈ 38 772 cm³

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:

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

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

Hope you understand

Step-by-step explanation:

1. 5 x 1.31= 6.55

2.  3x2.34=7.02

3.  6.55+7.02+13.38=  26.95

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

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.

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:

3

Step-by-step explanation:

Start by applying the order of operations which in this case would be left to right. -9 is the same thing as -9/1. Multiply the -9 by a 1 and you would just get -9. Multiply the 1 by 4 and you would get 4, so now you have -9/4. You can remember decimals by seeing them in terms of 1. 0.25 is 1/4, 0.5 is 1/2, and so 0.75 is 0.25 tripled, which would be 1/4 tripled or 3/4. Now with dividing, you can just multiply -9/4 by the reciprocal, which would be to flip the other fraction, which would give us 4/-3, and 4x-9 is -36 and -3x4 is -12 which would give us -36/-12. Dividing to negatives gives us a positive, and 36/12 is the same as 3/1 which would give us 3. Hope this helps!

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:

21

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

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)

The points (-5,-1), (1,-1), (-2,-4), (-2, 2) are presented on the coordinate plane.
