Add 2 then add 4! I dont get it at all plz help!

Answers

Answer 1
The question could be asking one of two things. If it is asking for you to create an equation that represents that, the equation would be:

x+2+4

We can find this by breaking apart the question. Since we are not given a variable, we can assume x. Then, you can reference "add 2" for where I got the "+2." Finally, you can see the "add 4," which is where I got the "+4."

If the question is referring to simple addition, you can simply add these numbers together. If you are really struggling, you should use a calculator and input these values. To improve your basic addition skills, you can practice with the popular elementary "finger-counting method" where you hold up the value of one of the numbers on one hand, and the other value on the other hand, and then count how many fingers are up.

If you need any further explanation, please let me know and I will be happy to assist you! :)

Mount Rushmore is a sculpture that was carved using a model with a scale of 1 in :1 ft. If the model of George Washington’s face was 5 ft, how tall was the face on the actual sculpture? a. 5 ft c. 60 ft b. 40 ft d. 72 ft

Answers

The face on the actual sculpture of George Washington’s is 60 feet .

What is scale factor?

The scale factor is a measure for similar figures, who look the same but have different scales or measures. Suppose, two circle looks similar but they could have varying radii. The scale factor states the scale by which a figure is bigger or smaller than the original figure.  

According to the question

Mount Rushmore is a sculpture that was carved using a model with a scale factor of 1 in = 1 ft.  

As we know

1 feet = 12 inches  

i.e

Scale factor is 12  for sculpture .

Now,

The model of George Washington’s face was 5 ft

As Scale factor is 12

So, the face on the actual sculpture

5 * 12 = 60 feet

Hence, the face on the actual sculpture of George Washington’s is 60 feet .

There are 375 books sold at Sid's Bookstore. The table below summarizes these books by genre. This info is presented in circle graph. Find the central angle measure for Self Help slice in graph. Mystery 99, romance 81, self help 90, cooking 57, biography 48.

Answers

When you plot the data in a pie graph, it looks like that shown in the picture. A circle is formed when you draw a point and connect it from end to end forming a complete revolution. One revolution equals 360°. Therefore, each piece of pie for each type of book is a fraction of one revolution. The fraction can be determined by dividing the number for a specific type of book to the total number of books. Specifically, the fraction for the Self Help slice would be 90/375 which is equal to 0.24 or 24%. Then, 24% of 360 is 86.4. Therefore, the central angle formed by the Self Help slice is 86.4°.

The central angle measure for the 'Self Help' slice in the circle graph is 86.4 degrees.

To find the central angle of the 'Self Help' slice in a circle graph (pie chart), we first need to calculate the total number of books sold, which is provided as 375.

We then take the number of 'Self Help' books which is 90, and determine what fraction of the total this represents. The fraction for 'Self Help' books is 90/375. A full circle has an angle of 360 degrees, so we multiply the fraction by 360 to find the central angle for that section of the pie chart.

= (90/375) * 360 = 0.24 * 360 = 86.4 degrees

Thus, the central angle measure for the 'Self Help' slice in the graph is 86.4 degrees.

express the confidence interval 0.38 p 0.54 in the form of p^ ± e

Answers

So, we have the interval 0.38 < p < 0.54:
Assume that p is in the middle of the given interval:
p = (0.54-0.38) / 2 = 0.08

Then, e can be calculated as follows:
e = end of interval - p = 0.54 - 0.08 = 0.46

The required expression can be written as follows:
p ± e = 0.08 ± 0.46

126 employees is 3% of what number of employees

Answers

First, define what it is that is being asked.

"of" in mathematics usually means that the numbers or values described are being multiplied.

And so the word problem becomes:
126 employees = 3% * x employees
Solve:

126 = .03 * x
x * .03 = 126
(x * .03) / .03 = 126 / .03

x = 4200 employees


Thus your answer is 4200 employees.
Your answer is 4,200 employees.

If 126 is equivalent to 3%, then we can say that 126/? = 3/100, which you can then use to find the answer by doing 126 ÷ 3 = 42, and then multiplying 42 by 100 to get 4,200.

I hope this helps!

PLZZ HELP!! A spherical ball just fits inside a cylindrical can, 16 centimeters tall, with a diameter of 16 centimeters. Which expression gives the volume of the sphere in cubic centimeters?

Answers

formula for volume of a sphere is V=4/3 x pi x R63

if diameter = 16 than radius = 16/2 = 8

 so the equation would be 4/3 x pi x 8^3

Answer:

Option [tex]V=\frac{4}{3}\pi (8^{3})\ cm^{3}[/tex]

Step-by-step explanation:

we know that

The volume of a sphere is equal to

[tex]V=\frac{4}{3}\pi r^{3}[/tex]

In this problem we have

[tex]r=16/2=8\ cm[/tex] -----> the radius is half the diameter

substitute

[tex]V=\frac{4}{3}\pi (8^{3})\ cm^{3}[/tex]
