Answer:
80
Step-by-step explanation:
you can divide the shape into a square and a rectangle, the square being the 7 by 10 area. by that logic, you can find the area of that portion to be 70. now you have the cut off rectangle to find, and you know one side is 2. to find the other side, you have to subtract 7 from 12 because by doing that you get the value of just that portion of the side. by doing that you get 5. going from there, you can multiply 2 by 5 to get 10 for the area of the rectangle. now you have to add 70 and 10, and you get 80!

Answers
Answer:
Step-by-step explanation:
First you put the negative sign away for the end and then you switch the problem to 20.5 - 6. Then you put the 0.5 away for later too. 20 - 6 is equal to 14. Then you add the 0.5 back to the number. So it is equal 14.5 and the you put the negative sign back on to get the final answer of -14.5.

299 divided by 21 step by step
Answers
Start by setting it up with the divisor 21 on the left side and the dividend 299 on the right side like this:
2 1 ⟌ 2 9 9
Step 2:
The divisor (21) goes into the first digit of the dividend (2), 0 time(s). Therefore, put 0 on top:
0
2 1 ⟌ 2 9 9
Step 3:
Multiply the divisor by the result in the previous step (21 x 0 = 0) and write that answer below the dividend.
0
2 1 ⟌ 2 9 9
0
Step 4:
Subtract the result in the previous step from the first digit of the dividend (2 - 0 = 2) and write the answer below.
0
2 1 ⟌ 2 9 9
- 0
2
Step 5:
Move down the 2nd digit of the dividend (9) like this:
0
2 1 ⟌ 2 9 9
- 0
2 9
Step 6:
The divisor (21) goes into the bottom number (29), 1 time(s). Therefore, put 1 on top:
0 1
2 1 ⟌ 2 9 9
- 0
2 9
Step 7:
Multiply the divisor by the result in the previous step (21 x 1 = 21) and write that answer at the bottom:
0 1
2 1 ⟌ 2 9 9
- 0
2 9
2 1
Step 8:
Subtract the result in the previous step from the number written above it. (29 - 21 = 8) and write the answer at the bottom.
0 1
2 1 ⟌ 2 9 9
- 0
2 9
- 2 1
8
Step 9:
Move down the last digit of the dividend (9) like this:
0 1
2 1 ⟌ 2 9 9
- 0
2 9
- 2 1
8 9
Step 10:
The divisor (21) goes into the bottom number (89), 4 time(s). Therefore put 4 on top:
0 1 4
2 1 ⟌ 2 9 9
- 0
2 9
- 2 1
8 9
Step 11:
Multiply the divisor by the result in the previous step (21 x 4 = 84) and write the answer at the bottom:
0 1 4
2 1 ⟌ 2 9 9
- 0
2 9
- 2 1
8 9
8 4
Step 12:
Subtract the result in the previous step from the number written above it. (89 - 84 = 5) and write the answer at the bottom.
0 1 4
2 1 ⟌ 2 9 9
- 0
2 9
- 2 1
8 9
- 8 4
5
You are done, because there are no more digits to move down from the dividend.
The answer is the top number and the remainder is the bottom number.
Therefore, the answer to 299 divided by 21 calculated using Long Division is:

how is the answer 4??
Answers
Answer:
see below
Step-by-step explanation:
log sqrt5 (25) = y
we know that loga (b) = c can be rewritten as a^c = b
sqrt(5) ^ y = 25
Rewriting sqrt(5) as 5^1/2 and 25 as 5^2
5^1/2 ^ y = 5^2
we know a^b^c = a^ (b*c)
5 ^ 1/2y = 5^2
1/2y = 2
y = 4

Answer:
55 degrees
Step-by-step explanation:
Add the expressions up and set up an equation.
( 2 x − 29 ) + ( x + 23 ) = 90 Simplify and solve for x.
3 x − 6 = 90 3 x = 96 x = 32 Find angle B.
x + 23 = 32 + 23 = 55
Hope this helps, have a nice day/night! :D
Answer:
m∠B = 61°
Step-by-step explanation:
Complementary means two angles that add up to the sum of 90°.
Since we are given m∠A = 29°, subtract 29° from 90°.
90 - 29 = 61
m∠B = 61°

Subtract 3x from both sides to isolate the -12:
3x - 12 = 11x
3x - 3x - 12 = 11x - 3x
-12 = 8x
8x = -12
Divide both sides by 8:

Question A, Part 1,
A media company wants to track the results of it's new marketing plan, so the video production manager recorded the number of views for one of the company's online videos. Thw results of the first 5 weeks arw shown in the table.
Weeks x, 0, 1, 2, 3, 4, 5
Views F(x), 5,120, 6,400, 8,000, 10,000, 12,500, 15, 625
Write an equation to model the relationship between the number of weeks, x, and the number of views F(x). Enter the correct answer in the box by replacing the values or a and b
f(x) = a(b)^x

Answers
Answer:
A) [tex]f(x)=5120(1.25)^x[/tex]
B) [tex]f(x)=4800(1.5)^x[/tex]
C) see below
Step-by-step explanation:
Part A
Hopefully this formatting looks ok:
| Weeks x | Views f(x) |
| ------------ | -------------- |
| 0 | 5120 |
| 1 | 6400 |
| 2 | 8000 |
| 3 | 10000 |
| 4 | 12500 |
| 5 | 15625 |
| ------------ | -------------- |
That's my attempt at a table.
We need an equation in the form of:
[tex]f(x)=a(b)^x[/tex]
where a is the starting value and b is the growth factor.
First, check the difference between each week:
[tex]6400 - 5120=1280\\8000 - 6400=1600\\10000 - 8000=2000\\12500 - 10000=2500\\15625 - 12500=3125\\[/tex]
Then, check the scale factor for each of the differences:
[tex]16000\div 12080 = 1.25\\2000\div 1600=1.25[/tex]
etc..
The difference grows by 1.25x each week. That is, a grow factor of 1.25.
Now that we have both the starting value and the grow factor, we can write the equation:
[tex]f(x)=5120(1.25)^x[/tex]
If you want to test it, for example, calculate for the 3rd week:
[tex]f(3)=5120(1.25)^3\\f(3)=5120(1.953125)\\f(3)=10000[/tex]
Part B
This is very similar to Part A. The starting value and growth factor are given this time, so all you need to do is write the equation with the new values.
[tex]f(x)=4800(1.5)^x[/tex]
Part C
The initial number of video views (5120) was more than the initial number of site views (4800), and the number of video views grew (1.25) by a smaller factor than the number of site visits (1.5).
The difference between the total number of site visits and the video views after 5 weeks is 20,825.
[tex]f(5)=5120(1.25)^5=15625 -video\\f(5)=4800(1.5)^5=36450-site\\36450-15625=20825[/tex]
The equation to model the relationship between the number of weeks and the number of views will be f(x) = 5120(1.25)^x
How to depict the equation?From the information given, the difference in the views will be:
6400 - 5120 = 1280
8000 - 6400 = 1600
10000 - 8000 = 2000
The scale factor will be:
= 1600/1280 = 2000/1600
= 1.25
Therefore, the growth factor is 1.25.
The equation to model the relationship between the number of weeks, x, and the number of site visits is 4800(1.5)^x.
Lastly, the difference between the total number of visits and the video views will be:
= 4800(1.5)^5 - 5120(1.25)^5
= 36450 - 15625
= 20825
