Answer:

The answer to your question is 1 = 69°

Step-by-step explanation:

To solve this problem remember that the sum of the internal angles in a triangle equals 180°.

Let the third angle of the triangle be x.

             39° + 30° + x = 180

Solve for x

             x = 180 - 39 - 30

             x = 111°

Angle x and angle 1 are supplementary so their sum equals 180°.

            111° + 1 = 180

                      1 = 180 - 111

                       1 = 69°

Anna is reading a 300-page book. She can read a page in two minutes. If she has finished reading 75 percent of the pages, how ma
Daniel [21]

Answer:

150 minutes

Step-by-step explanation:

If Anna read 75% of her 300-page book, then she has already read:

300 × 75%

= 300×0.75

= 225

225 pages.

If Anna has already read 225 pages, then she has:

300 - 225 = 75

75 pages left still to read.

If Anna reads 2 minutes per page, then she has

75 × 2 = 150 minutes.

She has 150 minutes of reading left to finish her book.

By the way, it's weird to say you have 150 minutes of something to do. In real life 150 minutes = 2 1/2 hours. jfyi. Have a great day!

List 3 values that would make this inequality true 48 < 6n​
icang [17]

Answer:

Step-by-step explanation:

Turn the question around so it is easier to see.The open end is closest to n.

6n>48          Divide by 6

6n/6>48/6

n > 8

So all you have to do is choose 3 values greater than 8

How about 9,10,11

Help me solve please! The math club has 57 members who are in sixth or seventh grades. There are twice as many sixth graders as
saul85 [17]
We know there is 57 members are in the math club and there is twice as many sixth grades than the seventh. To find out how many sixth graders are in the club, we do:

x = seventh graders
2x = sixth graders

2x + x = 3x

57=3x
57 ÷ 3 = 3x ÷3
19 = x

So there is 19 seventh graders and 19×2= 38 sixth graders
