On Sunday, the wind chill temperature reached −36 °F. On Monday, the wind chill temperature only reached 1 4 of Sunday's wind chill temperature. What was the lowest wind chill temperature on Monday? A −144 °F B −36 1 4 °F C −9 °F D −40 °F
Answers
Answer:
(A) -9 °F
Step-by-step explanation:
On Sunday, the wind chill temperature reached - 36 °F. On Monday, the wind chill
temperature only reached¼ of Sunday's wind chill temperature. What was the
lowest wind chill temperature on Monday? (A) -9 °F (B) -36¼°F (C) -40 °F (D) -144 °F
Sunday temperature = - 36 °F
Monday temperature = ¼ of Sunday's wind chill temperature
Monday = 1/4 of - 36 °F
= 1/4 * -36 °F
= (1 * -36)/4 °F
= -36/4 °F
= -9 °F
Monday temperature = -9 °F
The correct answer is (A) -9 °F

Tara bought one share of Apple stock in 2018 for $43.75. Then, three years later, she sold it for $136.76. How much money did she gain/lose with this stock? What was her return on investment?
Answers
Answer:
Gain= $93.01
ROI= 212.59%
Step-by-step explanation:
Given data
Cost of apple share in 2018 = $43.75
Sale price of apple share= $136.76
1. Her gain is
Gain= Sales price- Cost price
Gain = 136.76-43.75
Gain= $93.01
2. ROI is
ROI= Gain/cost*100
ROI= 93.01/43.75*100
ROI=2.1259*100
ROI= 212.59%

5ft and 12ft What is the length of the hypotenuse? feet
Answers
Answer:
The answer is 13 feet.
Step-by-step explanation:
Assuming that the lengths 5ft and 12ft are the legs of the triangle, use the Pythagorean Theorem to find the unknown length of the hypotenuse:
a^2 + b^2 = c^2
Now, simply plug in the values of the triangle legs:
5^2 + 12^2 = c^2
25 + 144 = c^2
169 = c^2
c = 13
Answer:
13 ft
Step-by-step explanation:
The formula to find the length of the hypotenuse is:
[tex]a^2+b^2=c^2[/tex]
---------------------------------------------------------------------------------------------------------------
So:
25 + 144 = 13

what's the value of x and y?
Answers
Answer:
x = 45 and y = 90
Step-by-step explanation:
Let the third angle be z
z = 180 - 135 (Linear Pair)
z = 45
Since its an iscosceles triangle,
<z = <x (angles opposite to equal sides have equal angles)
<x = 45 degree
<z + <x + <y = 180
45 + 45+ <y = 180
90 + <y = 180
<y = 180 - 90
<y = 90
Therefore x = 45 and y = 90
Hope u understood please mark as brainliest
Thank You
Answer:
x= 45°
y= 90°
Step-by-step explanation:
x= angles on a straight line add up to 180°. 180°-135° = x.
y= x+y=135° & x =45°
135°- 45° = y

You work at a public golf course. You have a budget of $300 for supplies for the month. The golf course can buy golf balls at a price of $0.80 each.
Write an inequality that states the number of golf balls you can buy at this price and still have $200 left in your budget for other items.
(please give nice clear real answers otherwise you will be reported, thank you soo much!)
Answers
Answer:
200 + 0.8x = 300
200 + 0.8x = 300
- 200 - 200

0.8x = 100
---------------
0.8 0.8
x = 125
Step-by-step explanation:
You have a TOTAL of 300 and want to spend it on the golf course. 200 MUST REMAIN in order to purchase other items. Golf balls are at a price of 0.8 EACH. The amount of golf balls that can be purchased is unknown so we can place x as the number of balls purchased for 0.8 each.
