Answer:

So first you know automatically that either side of the line is 180 degrees. So 180-155 would get you 25 degrees so you now know that y=5. we know that it is also a right angle therefore you divide 65 (x-90) by 13 and you get that x is also equal to five

The graph shows Melissa's heart rate in beats per minute be) during the tirst few minutes other cool down after
sesenic [268]

Answer:

The domain is {1,2,3,4,5}

The range is {150,135,120,105,90}

Step-by-step explanation:

Domain is the set of x-values (x axis) and Range is the set of y-values (y axis).

Now if you look at the relation (points given), you can see the 5 points corresponds to 1,2,3,4, adn 5 in the x axis (minutes). So this is the domain - 1,2,3,4,5.

If we look at the y-axis (Heart Rate) , the values corresponding to 1,2,3,4,and 5 are 150, 135, 120, 105, and 90. These are the range.

Hence the last choice is the correct answer.

HURRY NEED HELP NOW 42 POINTS NEED 1 PARAGRAPH FOR EACH QUESTION there are 2 photos I put up and that where the questions are.
Shtirlitz [24]
1. All you have to do to find the area of the figure. IS first find the area of the rectangle. This is easy because all you have to do is base times height. 

22 x 17 =  374

Now to find the area of the triangle all you have to do is  do base times height like a rectangle, but then divide it by 2 afterwords.
19 x 12 = 228 ÷ 2  = 114.

Now add the two area's together:

374 + 114 = 488.

Just do the same with the one below, I've altered the pic a bit to make it easier.

Write a system of equations to describe the situation below, solve using elimination, and fill in the blanks. Tori hosts a podca
Oksana_A [137]

Answer:

x = minutes of Tori's podcast = 88 minutes

y = minutes of Wendy's podcast = 129 minutes

Step-by-step explanation:

Let

x = minutes of Tori's podcast

y = minutes of Wendy's podcast

40x + 16y = 5,584 (1)

27x + 11y = 3,795 (2)

Multiply (1) by 11 and (2) by 16

440x + 176y = 61,424 (3)

432x + 176y = 60,720 (4)

Subtract (4) from (3) to eliminate y

440x - 432x = 61,424 - 60,720

8x = 704

x = 704/8

x = 88

Substitute x = 88 into (1)

40x + 16y = 5,584 (1)

40(88) + 16y = 5,584

3,520 + 16y = 5,584

16y = 5,584 - 3,520

16y = 2,064

y = 2,064/16

y = 129

x = minutes of Tori's podcast = 88 minutes

y = minutes of Wendy's podcast = 129 minutes
