Answer:
It’s 42
Step-by-step explanation: when Quinn return home, it was 0 minutes he turned on the air conditioner. So temperature at that time is equal to value of Q when t=0
Q=42-0.7t
=42-0.7(0)
=42
Answer:
2√34
Step-by-step explanation:
The vertical change is 6 and the horizontal change is 10.
Thus, the length of the diagonal (hypotenuse) is
6^2 + 10^2 = 36 + 100 = 136 = 4*34
Taking the positive square root of this 4*34, we get 2√34.
The length of the line / diagonal / hypotenuse is 2√34.
Answer:
y = 1/3x -3
Step-by-step explanation:
Answer:
w/2 = 7.5/5
3kg
Step-by-step explanation:
Remaining question below:
Which proportion could Maddy use to model this situation?
a. w/2 = 7.5/5
b. w/7.5 = 5/2
Solve the proportion to determine the weight of a 2 liter jug.
_____kg
5 liters jug of sport drink weighs 7.5kg
2 liters jug of sport drink will weigh x kg
Find w
Ratio of weight to volume
7.5kg : 5liters=7.5/5
wkg : 2 liters=w/2
Equates the ratio
7.5 / 5 = w / 2
Cross product
7.5*2=5*w
15=5w
Divide both sides by 5
3=w
w=3kg
Therefore, weight of the 2liters jug of sport drink is 3kg
2r + 6 = 16
minus both sides by 6
2r=10
divided both sides by 2
r=5
9(x-36)=18
9x-324=18
plus both side by 324
9x=342
divided both sides by 9
x=38
