Answers

Answer 1
Answer: I am not sure how to show you how to do a dot plot on this website, but to see how to do a dot plot

b) Put everything in order and find the middle
10, 10, 10, 20, 30, 30, 30, 30, 40, 50, 50, 50, 60, 60, 70, 70, 2040
                                             ^^
So 40 is in the middle, making it the median

c) Add all of the values together and divide by the total number of values.
10 + 10 + 10 + 20 + 30 + 30 + 30 + 30 + 40 + 50 + 50 + 50 + 60 + 60 + 70 + 70 + 2040 = 2660
2660 / 17 = 156.5

Yesterday, a Bakery baked 54 loaves of bread in 20 minutes today the bakery needs to bake 375 loaves of bread at this rate predict how long it would take to bake the bread

Answers

There are 54 can go into 375, 6 times. So if 54 can be done in 20 mins, you do 6 x 20 =120mins. Then you divide by 60 mins and you'll get 2 hours. so 2 hours is your answer.
it would take about 2 hours and 20 mins but they would have 3 leftovr

How to solve 6x+5x-4=2x-8

Answers

6x + 5x - 4 = 2x - 8
   11x    - 4 = 2x - 8
   11x  - 4 (-2x) = 2x - 8 (-2x)
     9x  - 4     = -8
     9x  - 4 (+4) = -8 (+4)
     9x            =     -4
     9x (/9)     =      -4 (/9)
      x             =     - (4)/(9)
6x+5x-4=2x-8~~~First we simplify(add 6x and 5x)
11x-4=2x-8~~~Now add 4 to both sides
       +4      +4
11x=2x-4~~~~Remove 2x from both sides now.
-2x   -2x
9x=-4~~~~Now divide by 9x
÷9x ÷9x

A pathway divides a rectangular garden into two parts as shown. Find the measure of angle A

Answers

Answer:

A=101°

Step-by-step explanation:

The two lengths of the rectangle are parallel and therefore the sides of the path form two parallel transversals.

The angle marked 79° and the angle marked A are supplementary ( they add up to 180°)

A+79=180°

A=180-79

=101°

Answer:

m < A = 101 degrees.

Step-by-step explanation:

The transverse line crosses 2 parallel lines (opposite angles of a rectangle are parallel) ,  so the same side angles add up to 180 degrees.

m < A + 79 = 180

m < A = 101 degrees.

Glenn swam 2 laps every morning for 7 day. in addition to the laps he swam each morning, he swam 3 laps with his friends on Tuesday and Thursday. write the expression that show the number of laps he swam during the week. evaluate the expression to find the total number of laps he swam that week.

Answers

Answer:

Expression = 2 × 7 + 3 + 3

Evaluation of the expression = 20

Step-by-step explanation:

Number of laps Glenn swam every morning = 2

Number of days for which he swam these laps = 7 days

⇒ Number of laps swam in a week = 2 × 7

Number of laps swam with his friend on Tuesday = 3

Number of laps swam with his friend on Thursday = 3

So, Expression that show the number of laps he swam during the week = 2 × 7 + 3 + 3

By evaluating the above expression, the total number of laps he swam that week = 14 + 3 + 3 = 20 laps
The answer is 15 because its evaluates

Answers

32 cubic inches of cards
V=area of bsase times height
area of base=4*8=32
32=32*height
1=height
card stack is 1 inch high

find volume of box
v=8*4*4=128

32 cubic inches of cards
percent means parts out of 100
x%=x/100
32/128=0.25/1
0.25/1 times 100/100=25/100=25%

answer is 25%
