Answer:

B. 20 weeks

Step-by-step explanation:

I am using the graphing calculator my school uses for exams. But here is the step by step anyway

5x + 36 = 2x + 96

(5x - 2x) + 36 = (2x - 2x) + 96

3x + 36 = 96

3x  + (36 - 36) = (96 - 36)

3x = 60

(3x ÷ 3) = (60 ÷ 3)

x = 20

x represents weeks

Step-by-step explanation:

The dimensions of matrix id determined by it's no. of rows x no. of columns

Since this matrix has 4 rows and 1 column, hence 4 x 1

Answer:

23. 3

24. 9

25. 22

26. 2

Step-by-step explanation:

Answer:

23. 3

24. 9

25. 22

26. 100 I think

Step-by-step explanation:

23. 15 x 1/5 = 3

24. 45 x 1/5 = 9

25. 7 x 2 = 14 + 8 =22

26. 50 x 1/5 = 10, 10^2 = 100

Answer:

Step-by-step explanation:

Answer:

39/50 and 0.78

Step-by-step explanation:

78% = 78/100 (or 78 hundredths) = 0.78

39 ÷ 50 = 0.78

Answer:

39/50

Step-by-step explanation:

Someone reported my comment becuase they were mad lol.

Step-by-step explanation:

1. 10-(2+3) = 5

2. 2x3 - 10 = -4

3. 3 x (4-2) = 6

4. (3+5) / 4 = 2

5. (5-2) x 3 = 9

6. (9-4) + 5 = 10

Answer:

1. 50 m

2. 80 cm

Step-by-step explanation:

1. There are 2 triangles, subtract the area of 1 of them from the other.

The triangle that needs to be subtracted: b = 20 m, h = 10 m

A = 1/2b * h = 1/2(20) * 10 = 10*10 = 100 m

The big triangle, the one that needs to be subtracted plus the one you need to find the area of: b = 20 cm, h = 15 cm, 1/2(20) * 15 = 10 * 15 = 150

150 - 100 = 50 c

2. Divide it into 3 parts:

1- 3*4 = 12

2. 7*(4 + 4) = 7*8 = 56

3. [(4 + 4) * (13 - 7 - 3)]/2 = (8*3)/2 = 24/2 = 12

12 + 56 + 12 = 80 cm

Answer:

Part A: 56

Part B: 43.9

Part C: I think the medain is more apropriate in this situation because it takes out the outlier , 3, that is affecting the mean

Step-by-step explanation:

Part A: To calculate the median you must have all of the numbers in numerical order so, 3,31,37,56,57,61,62, The medain is the number in the middle or closet to the middle. In this case 56 is directly in the middle so 56 is your median.

Part B: To find the mean you must add all of the values together and then divide by the number of values you have so when you add 3+31+37+56+57+61+62 it equals 307 and you divide it by 7 because there are 7 numbers in this data set and you get 43.9 when you round to the nearest tenth.

Part C: explanation in answer.

Hope this helps :)

Answer:

for part a you can just go to an excel numbers in a column then click sum then click medien then select the column.

Step-by-step explanation:

Answer:

The total volume of the bedroom and closet is 42  feet or sq2

No, it doesn't make sense to find the bedroom floor and closet floor area combined because this is abt the height and volume, not the flooring plan (area)

Step-by-step explanation:

You multiple 7*6 to get the 42 answer

Answer:

The total​ cost, c, of renting a canoe on either river for n hours can be represented by an equation. Write and graph a system to find how many hours you have to rent a canoe for the cost to be the same on both rivers.

Step-by-step explanation:

Answer:

82 or 5.3

Step-by-step explanation:

As you know a whole triangle is 180° so if you subtract 16 from 180 you get 164 so then you just divide it by three and you get 54.3.

Or if that is wrong try dividing 16 into three and you get 5.3.

I'm really sorry if neither one of these are right!

Answer:

Area: 312

Perimeter: 75

Step-by-step explanation:

Area is l·w

20·16=320

two corners aren't filled

320-9-9=318

Add all the sides for perimeter

17+3+3+13+20+13+3+3=75

Answer:

281 m squared

Step-by-step explanation:

What we can first do is find the top length so we can do

17+3+3=23

then we can multiply it by the side length to get the whole rectangle

23*13=299

and we know each of the little areas is 9, and there are two so

9+9=18

and we can subtract that from the whole rectangle

299-18=281

Answer:

10.) 16/35 you add up how many cards total for the bottom number then you add up how many cards aren't red for the top number

14.) 1/2 same explaination as before

Answer:

(17.91b+27)+22 is the expression

and the estimate will be 121 because u will do 18 times 4=72 and the add 22 and then 27.
