Answer: 0°F
Step-by-step explanation:
Temperature on a winter morning = -11°F
Increase in temperature noticed in the afternoon = +11°
Tthe temperature when Guadalupe checks in the afternoon will be:
= Temperature in the morning + Increase in temperature
= -11°F + 11°
= 0°
The temperature in the afternoon was 0°F.
(8y + 2) + (25y - 20) = 180 {interior angles on the parallel lines add up to 180)
Remove brackets:
8y + 2 + 25y - 20 = 180
Combine like terms:
33y - 18 = 180
Add 18 to both sides:
33y = 198
Divide both sides by 33:
y = 6
Answer: y = 6
(10x) + (8y + 2) = 180 {Adjacent angles on a straight line add up to 180)
Plug y = 6 into the equation:
(10x) + (8(6) + 2) = 180
Evaluate the bracket:
10x + 50 = 180
Subtract 50 from both sides:
10x = 130
Divide both sides by 10:
x = 13
Answer: x = 13

Answer:
Perimeter≈113.57 and Area= A≈498.84
Step-by-step explanation:
Ok so the Perimeter is approximately 113.57. the formula of a perimeter of a right triangle is P=a+b+√a²+b²
so since a and b are the leg in the right riangle then the value we are gonna be working with are 24 and 41.57
so basically the equation states this: P=24+41.57+√24²+41.57²
so 24+41.57 is 65.57
24²=576 and 41.57²=1728.1(rounded) add that and you get 2304.1. the square root of 2304.1 is 48.00104166 or just 48. add that to 65.57 and you get 113.57
Now for area.
the area of right triangle is ab/2
so 24times 41.57 divided by 2
24 times 41.57= 997.68
divide that by 2 and you get 498.84
