Answer:

31/33

Step-by-step explanation:

Answer:

p=1                                  p = -5/3

Step-by-step explanation:

1-|3p+1|=-3

Subtract 1 from each side

1-|3p+1| -1=-3-1

-|3p+1|=-4

Divide by -1

|3p+1|=4

The absolute value has two solutions one positive and one negative

3p+1 = 4            3p+1 = -4

Subtract 1 from each side

3p+1-1 = 4-1            3p+1-1 = -4-1

3p = 3                         3p = -5

Divide by 3

3p/3 = 3/3                    3p/3 = -5/3

p=1                                  p = -5/3

Answer:

p=-5/3,1

Step-by-step explanation:

Subtract 11 from both sides.

-|3p+1|=-3-1

−∣3p+1∣=−3−1

2 Simplify  -3-1−3−1  to  -4−4.

-|3p+1|=-4

−∣3p+1∣=−4

3 Multiply both sides by -1−1.

|3p+1|=4

∣3p+1∣=4

4 Break down the problem into these 2 equations.

3p+1=4

3p+1=4

-(3p+1)=4

−(3p+1)=4

5 Solve the 1st equation: 3p+1=43p+1=4.

p=1

p=1

6 Solve the 2nd equation: -(3p+1)=4−(3p+1)=4.

30.65-(30.65*0.60)=30.65-18.39=12.26

Answer:

1017 cm³

Step-by-step explanation:

To find the volume of this figure we will first need to divide it into 2 sections. First, we will find the volume of the semicircle on top then the cone at the bottom!

1) Semicircle

The simplest way of doing this is to find the volume as if it was a circle and then divide that result by 2! (\(\frac{4}{3}\)πr³)

2) Cone

To find the volume of the cone we need to apply the equation πr²\(\frac{h}{3}\) (where h = height)

3) Add

Hope this helps, have a lovely day! :)

a) The step where Mardie first made an error is given as follows: Step 1, as the negative sign means that the sign of each term inside the parenthesis should be changed.

b) The correct expression is given as follows: -8.6b + 28.

The expression in the context of this problem is defined as follows:

(-3.78b + 12) - (4.82b - 16).

The negative sign before the parenthesis means that the sign of each term inside the parenthesis is changed, hence:

-3.78b + 12 - 4.82b + 16.

This is the step where Maddie made the first error.

Then, to simplify the expression, we combine the like terms, as follows:

b(-3.78 - 4.82) + 12 + 16 = -8.6b + 28.

Can you show the graph please?

Step-by-step explanation:

Answer:

300

Step-by-step explanation:

If the yearly salary increase is changed to $ ? , the new equation would be y = ? x + ?.

Let $e for new empolyee.

Let $s for slope for salary.

We know if the starting salary for a new employee is changed to $35,000 and the yearly salary increase is unchanged, the new equation would be y = ?

y = ? the question mark will represent x.

Because $35,000 is the only number, that will be our main goal.

So $35 in shorten, added 25, 20. Which is 45.

With that we do +200 - 45. 155.

So 45+255=300

Answer:

The scaling factor is 4.

Step-by-step explanation:

To find the scaling factor from A to B, we must know that these are similar triangles.  Since this is not stated in the problem, we will assume these are similar triangles.

Similar triangles simply have the same scaling ratio, allowing for any size triangle to be created with the same relative dimensions.  With this in mind, let's check to see the multiple of each side by simply taking the sides of the triangle B divided by the sides of triangle A.

40 / 10 = 4

44 / 11 = 4

72 / 18 = 4

Notice how each of the sides from triangle B to triangle A has the same multiple, 4.  This tells us that the scale from A to B is 4.

Hence, the scaling factor is 4.

Cheers.

Answer: There is 5 non blue sock in Josh's drawer

Step-by-step explanation:

The denominator shows the total of nonblue and blue socks. So there are 7 non-blue and blue socks in the drawer after he removes 3 non blue socks.To find how many non-blue where in the drawer originally you need to find how many non blue are in the draw after removing the three. So you subtract 7 from 5 which gives you 2. So there are 2 non-blue socks in the drawer after removing the three. Now you need to find how many non-blue were there before he removed the three. So add the 3 non blue socks that he removed to the two that were there after which gives you five.

9:6=36:24

Step-by-step explanation:

9 is equal to 1.5x 6 and 36 is equal to 1.5x 24 so both can be simplified to a ratio of 3:2.

Answer:

A function is a mathematical relation in which each input (domain value) is associated with exactly one output (range value). In other words, for a relation to be a function, each input can have only one corresponding output. Let's analyze the given pairings:

(a person’s age in years, that same person’s height in inches) - This can be a function because one person's age in years should correspond to a single height in inches.

(a person’s weight in pounds, that same person’s height in inches) - This can also be a function because one person's weight in pounds should correspond to a single height in inches.

(a person’s height in centimeters, that same person’s height in inches) - This can be a function because one person's height in centimeters should correspond to a single height in inches.

(a person’s telephone number, that same person’s height in inches) - This may not necessarily be a function. It's possible for two different people to have the same height in inches but different telephone numbers.

So, the pairings that always describe a function are:

(a person’s age in years, that same person’s height in inches)

(a person’s weight in pounds, that same person’s height in inches)

(a person’s height in centimeters, that same person’s height in inches)

These three pairings meet the criteria of a function, where each input corresponds to a unique output.

The pairing that always describes a function is option C. (a person’s height in centimeters, that same person’s height in inches)

A pairing describes a function when each unique input (domain element) is associated with exactly one unique output (range element). In other words, there should be no ambiguity or multiple outputs for a single input. Let's analyze the given pairings:

1. (a person’s age in years, that same person’s height in inches): This pairing may not always describe a function because multiple people can have the same age, but they might have different heights. So, there can be multiple outputs for the same input (age).

2. (a person’s weight in pounds, that same person’s height in inches): Similar to the first pairing, this may not always describe a function because different people can have the same weight but different heights.

3. (a person’s height in centimeters, that same person’s height in inches): This pairing describes a function because for each unique height in centimeters, there is only one corresponding height in inches.

4. (a person’s telephone number, that same person’s height in inches): This pairing may not always describe a function because multiple people can have the same telephone number, but they might have different heights. So, there can be multiple outputs for the same input (telephone number).

So, the pairing that always describes a function is: (a person’s height in centimeters, that same person’s height in inches)

Step-by-step explanation:

Answer:

SA = 578ft²

Step-by-step explanation:

First, we have to know the formula of finding the surface area of a rectangular prism.

Formula: 2(wl + hl + hw)

w = width l = length h = height

Next, we separate the composite figure into two rectangular prisms.

Since we have all measurements, let's use that to find the SA.

The first shape (to the left)

SA = 2(wl + hl + hw)

SA = 2(4 x 9 + 9 x 9 + 9 x 4)

SA = 2(36 + 81 + 36)

SA = 2(153)

SA = 306

Then, we do the other shape(to the right)

We know the measurement of length = 4 because it is the same measurement as the width

SA = 2(wl + hl + hw)

SA = 2(4 x 4 + 15 x 4 + 15 x 4)

SA = 2(16 + 60 + 60)

SA = 2(136)

SA = 272

Lastly, we add those two

306 + 272 = 578

Therefore, SA = 578ft²

You need to find the slope.

\(m=\frac{y_{2}-y_{1} }{x_{2}- x_{1} }\\m=\frac{-12-4 }{0-4 }\\m=\frac{-16}{-4}\\ m=4\)

Since the slope is 4, the answer is B.
