the perimeter of the triangle below is 38 units. Find the length of side WX. Write your answer without variables

Answers

Answer:

5.5

Step-by-step explanation:

Add each side of the triangle.

3z+z+1+4z-3 = 8z - 2

8z - 2 is equivalent to the  perimeter.

Since you know the perimeter is 38 units, you can set 8z-2 to 38.

8z-2 = 38

Solve for z. Subtract 2 from each side.

8z = 36

Divide each side by 8.

z = 4.5

Now solve for side WX.

WX = z + 1

WX = 4.5 + 1

WX = 5.5

Andrea paid $9.99 to join an online music service. If she purchases 12 songs each month at a cost of $0.80 per song, what will be the total amount she has spent after 6 months?

Answers

Answer:

$67.59

Step-by-step explanation:

$9.99 + 6(12×$0.80)

$9.99 + 6($9.60)

$9.99 + $57.6

$67.59

Did mentally, so feel free to double check! ❤

Give brainliest as you wish and follow me so i can get a notification to help you!❤

After 6 months of paying the subscription fee and buying 12 songs each month, Andrea will have spent a total of $67.59.

What are equation models?

The equation model is defined as the model of the given situation in the form of an equation using variables and constants.

Here,
To find the total cost of the songs,
= 12 songs × $0.80/song = $9.60

Then, the total cost of the subscription and the songs over 6 months:
= $9.99 + (6 × $9.60)
= $9.99 + $57.60
= $67.59.

So, after 6 months of paying the subscription fee and buying 12 songs each month, Andrea will have spent a total of $67.59.

Sanya currently earns $25.00 an hour at her job. Thanks to her hard work, her boss is going to give her a 15% raise. How much will she earn each hour after the raise?

Answers

Answer:

28.75

Step-by-step explanation:

We can do 15% of 25 which is 3.75. Add this on to 25, and get 28.75.

The amount she is earning each hour after the raise is $28.75 if Sanya currently earns $25.00 an hour at her job.

What is the percentage?

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

It is given that:

Sanya currently earns $25.00 an hour at her job. Thanks to her hard work, her boss is going to give her a 15% raise.

The raise = 15 % of 25 = 3.75

Total after raise = 25.00 + 3.75 = $28.7

Thus, the amount she is earning each hour after the raise is $28.75 if Sanya currently earns $25.00 an hour at her job. Thanks to her hard work, her boss is going to give her a 15% raise.

Answers

I can’t upload any working right now so I hope you’ll understand from an explanation, all it is is a hidden polynomial. You can say:

Let y=x^2
Then the equation becomes:
y^2 - 18y + 81
Factorise that to give you:
(y-9)(y-9) Or (y-9)^2
But remember, y=x^2. So the equation becomes:
(X^2-9)(X^2-9)

Solve x3 = 64 over 27

Answers

Answer:

x= 4/3

Step-by-step explanation:

Answer:

Hope it helps

Step-by-step explanation:

So you want to get x by itself.

x3= [tex]\frac{64}{27}[/tex]

You could simplify

x3=2.37037037037

Then just divide 3 on both sides

x=0.79012345679

Or you can divide a fraction by a whole number and just divide the numerator and the denominator by 3.

x= [tex]\frac{21.3}{9}[/tex] or just 2.36666666667.

The image above shows a linear pair. Solve for x:

x = 12.14
x = 12.14

x = 25
x = 25

x = 28.33
x = 28.33

Answer:

A. x ≥ -3 and x < 2, or -3 ≤ x < 2

Step-by-step explanation:

Remember solid dot means include, open dot means not include.

x ≥ -3: this means x is greater and equal (includes) -3.

x < 2: this means x is less than 2 and does not include it.

Answer:

A

Step-by-step explanation:

So on the number line you see a closed circle at -3 and an open circle at 2.

Closed circle represents it's either [tex]\leq[/tex] or [tex]\geq[/tex]. Open circle represents < or >.

So the first part has a closed circle at -3 and goes towards the right side. Since it does that, it would be [tex]x \geq -3[/tex].

The second part has an open circle at 2 and goes towards the left side. Since it does that, it would be [tex]x < 2[/tex].

To combine it together, it would get [tex]-3 \geq x < 2[/tex].

Since option A is [tex]x \geq -3[/tex] and  [tex]x < 2[/tex], or [tex]-3 \geq x < 2[/tex], A would be the answer.

O normal distribution

Answers

The answer is skewed in the right direction

The distribution of set A is a normal distribution

4 4

5

Notice that the plot above increase from 0, then reaches a maximum at 3, and then decreases from 3 to 5

This implies that it follows a bell curve.

When a distribution follows a bell curve, such data is a normal distribution.

Hence, the distribution is a normal distribution
