Answer:

  division of 16 by 3.2

Step-by-step explanation:

  2.5(4^2 ÷ 3.2 – 10(0.2) + 3)– 5.2

  2.5(16 ÷ 3.2 – 10(0.2) + 3) – 5.2

Next, he will perform multiplication and division inside parentheses, left to right.

  2.5(5 – 10(0.2) + 3) – 5.2 . . . . . Bryan's next step

  2.5(5 – 2 + 3) – 5.2

Then, he will finish evaluating inside parentheses by performing addition and subtraction left to right.

  2.5(3 + 3) – 5.2

  2.5(6) – 5.2

With parentheses evaluated, now we do multiplication and division, left to right.

  15 – 5.2

Finally, addition and subtraction left to right.

  9.8

the answer is maybe 99 i aint sure tho

Step-by-step explanation:

Answer:

x = 47

Step-by-step explanation:

We need to solve for the interior angle measure x. To get x, we know that the sum of the triangles angle measures are 180, so lets write an equation to find x.

\(x+102+31=180\)

Add like terms

\(x+133=180\)

Subtract 133 on both sides

\(x=47\)

To check our work, we can add the angle measures together so we know we got it right.

\(47+102+31=180\)

Answer:

x=48

Step-by-step explanation:

add 102 and 31 then subtract it by 180

Answer:

Step-by-step explanation:

Let’s mark the Triangle Points as Point A, Point B, Point C.

Point A = 1x°

Point B = 2x°

Point C = 3x°

We know that the Angle Sum of a Triangle is equal to 180°.

So, Point A + Point B +Point C = 180°

   = 1x° + 2x° + 3x° = 180°

   = (1 + 2 + 3)x° = 180°

   = 6x° = 180°

   = x° = (180/6)°

   = x° = 30°

|  —                                 —  |

|   Point A = 1 * 30° = 30°    |         ⇒

|   Point B = 2 * 30° = 60°   |         ⇒          Only Extra Information

|    Point C = 3 * 30° = 90°  |         ⇒

Answer:

B

Step-by-step explanation: The box represents the middle 50% of the data, with the bottom and top of the box representing the first and third quartiles, respectively. The line inside the box represents the median.

The whiskers extend from the box to show the range of the data, excluding outliers. Outliers are typically shown as individual points outside the whiskers.

Based on this information, we can see that the box in the box plot represents the middle 50% of the data. Therefore, the answer is B. The box, from 44 to 52, includes about 50% of the data.

Rise over run is the slope, m

m=2/5

a)  the slope is 2/5 = .4 which is below the boundary guideline.  So no this is not with in carpenter's guidelines

b) the image below show a line with slope 2/5 but with intercept 3

c) the stairs can be draw on the line with rise 2 run 5   from the line.  see image

d)equation is in image

a) count the squares

horizontal distance =3

vertical distance =3

b)  slope is vertical distance over horizontal distance  so m= 3/3 =1

Explanation:

The data from the stem-and-leaf plot is:

10,

24,25,26,

30,30,32,33,

40,45,46

Add up those values

10+24+25+26+30+30+32+33+40+45+46 = 341

Then divide over n = 11 which is the sample size.

341/11 = 31 is the arithmetic mean.

Answer:

341/11 = 31 is the arithmetic mean.

If 189 cost $1.31

756 cost $x

____________

756 *1.31 / 189 = $5.24 cost for second fabric

Second way;

(18x42) / (21x9) = 4 x 1.31 = $5.24

Answer:

C. 69°

Step-by-step explanation:

All three angles of a triangle add to 180°. You are given that one angle is 42° and for a isosceles triangle, the two remaining angles in the photo are equal so:

180° = 2x - 42°

138° = 2x

x = 69°

If you have any questions, please leave a comment.

Answer: The answer would be c.69

Step-by-step explanation:

Ms. Petersen ordered 30c cartons of chocolate milk in October.

brief detail

To solve the problem, we need to know the total number of cartons of chocolate milk that Ms. Petersen ordered in October.

If she ordered 15 cases of chocolate milk twice, she ordered a total of 30 cases of chocolate milk (15 x 2).

We are also told that each case contains c cartons of chocolate milk. So, the total number of cartons of chocolate milk that Ms. Petersen ordered is:

30 cases x c cartons per case = 30c cartons

explanation:

No of cartoon of chocolate milk

= c

No of cases ordered = 15*2

Each cartoon contains chocolate milk = 15*2*c

 =30 c
