Problem 23
A = 40
B = 3x+1
C = 3x+1
B and C are congruent, so they have the same angle measure

The three angles of any triangle add to 180 degrees
A+B+C = 180
40+(3x+1)+(3x+1) = 180
6x+42 = 180
6x = 180-42
6x = 138
x = 138/6
x = 23

Answer: B) 23

============================================================

Problem 24

AB is the midsegment parallel to XY
So AB is half that of XY
AB = (1/2)*XY
AB = (1/2)*28
AB = 14

Answer: B) 14

============================================================

Problem 25

Note the ratio of the given rectangle's sides: 7/12 = 0.583 roughly

Divide the answer choices in a similar fashion
A) 5/7 = 0.714
B) 14/36 = 0.389
C) 21/36 = 0.583
D) 21/48 = 0.4375

We get the same result in choice C as we did in the original rectangle

Answer: C) 21 ft x 36 ft

Daniel went to play soccer at a quarter to 6. His mom called him to come home for dinner at 20 minutes after 7. How many minutes
Minchanka [31]

Answer:

Daniel played soccer for 95 minutes

Step-by-step explanation:

1) If he started at a quarter to 6 this means he started at 5:45 as a quarter is 15 minutes.

2) If he finished 20 minutes after 7 he ended at 7:20

3) Add 15 minutes to get to 6:00.

4) Since 60 minutes are in an hour, add 60 minutes to get 7:00. This brings our total up to 75 minutes.

5) Add the last 20 minutes to get the total amount of 95 minutes spent playing soccer.

PLEASE HELP THANKS

AC would be equivalent to 4. I know that the triangle is a 90, 45, 45 triangle which means 2 of the angles AND sides are equivalent to each other. Since angle B is 45 degrees angle C has to be 45 degrees. Same goes for the sides. Since AB=4, AC=4. It wouldn't be BC bc that's the hypotenuse or the longest part of the triangle. AC wouldn't be equal to 2 since it won't follow the rule of a 90, 45, 45 triangle. :|

the width of a rectangle is 1/4 it’s length. the perimeter of the rectangle is 600ft. what is the length, in feet, of the rectan
vovikov84 [41]

Answer:

let length be l and breadth 1/4×l

perimeter of the rectangle =600ft

2(l+1/4×l)=600ft

(4l+l)/4=600/2

5l=300×4

l=1200/5=240ft

Step-by-step explanation:

240ft is the length of a rectangular.

Graph the set of points. which model is most appropriate for the set? (-6, -1)(-3, 2)(-1,4)(2,7)
lianna [129]
For this case, the first thing to do is to graph the following ordered pairs:
 (-6, -1)
 (-3, 2)
 (-1,4)
 (2,7)
 We observe that the graph is a linear function with the following equation:
 y = x + 5
 Note: see attached image.
 Answer:
 
The function that best represents the ordered pairs is:
 
y = x + 5
