Iron makes up 4.5% of the Earth's crust. Which is another way to write 4.5% of a value?

Answer:

B) 60

Step-by-step explanation:

5*2*3*2=60 types by multiplying all the categories together.

Answer:

option D 41

Step-by-step explanation:

since ∠N = ∠L

this means that MN = ML    (sides opposite to equal angles are equal)

thus

3x + 1 = 5x - 7

1 + 7 = 5x - 3x

8 = 2x

8/2 = x = 4

inserting values

3*4 + 1= 13

4*4-1 =15

5*4-7 = 13

adding all

13 + 13+ 15 = 41

option D 41

Step-by-step explanation:

Given:

Laura has 160 pounds of green beans at her vegetable stand.

She sells 10 pounds of green beans every hour.

To find:

The percent decrease in green beans after 3 hours.

Solution:

We have,

Beans sold in 1 hour = 10 pounds

So, Beans sold in 3 hours = 30 pounds

Decrease in green beans after 3 hours is 30 pounds.

Now,

[tex]\%\text{Decrease}=\dfrac{\text{Decrease in green beans after 3 hours }}{\text{Initial amount of green beans}}\times 100[/tex]

[tex]\%\text{Decrease in green beans after 3 hours}=\dfrac{30}{160}\times 100[/tex]

[tex]\%\text{Decrease in green beans after 3 hours}=\dfrac{300}{16}[/tex]

[tex]\%\text{Decrease in green beans after 3 hours}=18.75\%[/tex]

Therefore, the correct option is A.

Answer:  The flagpole is about 22.3 feet tall.

This is roughly the size of a two story building, assuming each floor is 10 feet or so.

Since this height is under 25 ft, this flagpole is in compliance with the regulation.

=====================================================

Work Shown:

The horizontal leg of the triangle is 36 ft. This is the adjacent leg to the reference angle 25 degrees.

The vertical leg of the triangle is x-5.5, and this leg is the opposite side to the reference angle 25 degrees.

Use the tangent rule to connect the opposite and adjacent sides.

Solve for x.

tan(angle) = opposite/adjacent

tan(25) = (x-5.5)/36

36*tan(25) = x-5.5

x-5.5 = 36*tan(25)

x = 36*tan(25)+5.5

x = 22.28707569358

x = 22.3 ft is the approximate height of the flagpole

Make sure your calculator is in degree mode.

The height is not over 25 ft, so this flagpole meets the requirements.

Answer:

The correct answer is: Option B: [tex]a_n = 25+(-4)(n-1)[/tex]

Step-by-step explanation:

Given sequence is:

25, 21, 17, 13,...

Here

a1 = 25

a2 = 21

a3 = 17

First of all we have to determine the common difference. Common difference is the difference between consecutive terms of an arithmetic sequence.

So,

[tex]d = a_2 - a_1 = 21-25 = -4\\d =a_3-a_2 = 17-21 = -4[/tex]

The explicit formula is given by:

[tex]a_n = a_1 + (n-1)d[/tex]

Putting the value of a1 and d

[tex]a_n = 25 + (n-1)(-4)\\a_n = 25-4n+4\\a_n = 29-4n[/tex]

Hence,

The correct answer is: Option B: [tex]a_n = 25+(-4)(n-1)[/tex]

7. -209

Answer:

1.) -7 + 10 = 3  (Different signs, so you subtract and keep the sign of the bigger number).

2.) -30 - 15 = -45 (same sign, so you just add and keep the same sign)

3.) 65 - 90 = -25 (Different signs, so you subtract and keep the sign of the bigger number).

4.) 100 + 120 = 220 (both positive,you add and keep the same sign, which is +)

5.) -32 + 89 = 57  (Different signs, so you subtract and keep the sign of the bigger number).

6.) 100 - 200 = -100  (Different signs, so you subtract and keep the sign of the bigger number).

2.) -75 - 12 = -87  (same sign, so you just add and keep the same sign)

Answer:

36

Step-by-step explanation:

The equation would turn out as 23--13

But when there are two negatives, it turns into a positive, creating the equation of 23+13

Then you add to equal 36.

The equation with the greater rate of change is y = 3x + 12, which has a rate of change of 3.

A linear equation is in the form:

y = mx + b

where y, x are variables, m is the rate of change and b is the y intercept.

Given the equations, the equation with the greater rate of change is y = 3x + 12, which has a rate of change of 3.

Step-by-step explanation:

to convert a mixed number to an improper fraction: take the big whole new on the right and multiply it by the denominators or number on the bottom of the fraction. then add thay amount to the numerator, or number on top and leave the denominator as it was before

example: 2 3/5 = 13/5

you can dissect the example to figure out the formula (formula is the way to solve an equation)

Answer:

Since you didn’t give us a mixed number is to turn into an improper fraction, I’ll show you how to do it.

Step-by-step Explanation:

First, you need to multiply the denominator by the whole number. Then, add the numerator to it. Lastly, you need to put the same denominator in that was from the mixed number to get an improper fraction. I’ll give you an example:

Look at the diagram below ↓

You can see that you need to multiply the denominator 4 and the whole number 2, which gives you 8. Then you add the numerator 3 to 8, which gives you 11. Lastly, you need to use the same denominator from the mixed, which was 4, and put it with the 11 to get the improper fraction [tex]\frac{11}{4}[/tex].
