37 is the answer, so you know that 53 is one of the angles given and there is a 90 degree angle, so all you do is 53+90=180, then you get 143=180, then subtract 180-143=37 and the real answer is 37. Hope this helps!! :)

Answer:

37 degrees

Step-by-step explanation:

The angles within a triangle always add up to 180 degrees. Right angles are always 90 degrees. 53 + 90 = 143 degrees. 180 - 143 = 37 degrees

Brooke has to set up 70 chairs in equal rows for the class talent show. But, there is not room for more then 20 rows. What are t

grin007 [14]

Answer:

The answer is 2, 5, 7, 10, and 14.

Step-by-step explanation:

Let x be the number of rows. There is not room for more than 20 rows:

x ≤ 20

Since all rows must be equal, when we divide 70 by x, we must get a whole number. So, we must find all divisors of 70 smaller or equal to 20 and they are: 2, 5, 7, 10, and 14.

So, the possibilities are:

2 rows with 35 chairs in each row

5 rows with 14 chairs in each row

7 rows with 10 chairs in each row

10 rows with 7 chairs in each row

14 rows with 5 chairs in each row

Hope this helps!!

Katie has a collection of nickels, dimes and quarters with a total value of

garik1379 [7]

10d+ 25q+5n= 805

D= n+8

Q= n+ 5

10d+ 25q+5n= 805

10(n+8)+25(n+5)+5n=805

10n+80+25n+125+5n=805

40n+205=805

40n=805-205

40n= 600

N=600/40

N= 15

D= n+8

D= 15+8

D= 23

Q=n+5

Q=15+5

Q=20

So 15 nickels ,23 dimes and 20quarters .

To check

15(0.05)= $0.75

23(0.10)=$2.30

20(0.25)=$5.00

Add it

5.00+2.30+0.75=8.05

7.30+.75=8.05

8.05=8.05

Here is a list of numbers: 3.9 , 7 , 3.3 , 1 , 1.4 , 1.7 , 2.1 , 3.3 , 5.2 State the median. Give your answer as a decimal.

Ber [7]

<h3>A median.</h3>

The "middle" of a sorted list of numbers. To find the Median, place the numbers in value order and find the middle number.

When there are two middle numbers we average them.

We have:

3.9, 7, 3.3, 1, 1.4, 1.7, 2.1, 3.3, 5.2

Let's sort the numbers from the smallest to the largest

1, 1.4, 1.7, 2.1, <u>3.3</u>, 3.3, 3.9, 5.2, 7

<h2>The median is 3.3</h2>
