Please see the answers below:
Step-by-step explanation:
The wrong answers are deleted only the correct answers are listed below:
- Ryan earns $45 for 5 hours of work. The unit rate is $9 for 1 hour.
- Jenna can drive her car 110 miles on 5 gallons of gasoline. The unit rate is 22 miles per gallon.
- Claire saves $320 in 16 weeks. The unit rate is $20 per week.
- % increase in price of gas = [(New Price - Original Price) / Original Price] x 100
% increase in price of gas = [($2.48 - $2.18) / $2.18] x 100
% increase in price of gas = [$0.3 / $2.18] x 100
% increase in price of gas = 13.76%
Answer:
$1,635
Step-by-step explanation:
she makes $45 a year so if you multiply that by 3 you get $135
Slope = (y2-y1)/(x2-x1) = (8-2)/(3-1) = 6/2 = 3. So the answer is c.
A=1/2 B×h
285=1/2×B×15
B=38 feet, so the base of the triangle is 38 feet. Hope it help!
Answer:
) = 23 °C
ii) = 4.4° C
Step-by-step explanation:
i) The temperature on the surface of the planet.
At the surface of the planet the height is Zero
Therefore, X = 0
Thus; using the equation, the temperature, y will be;
y = 23 - 5x
y = 23 - 5(0)
= 23 °C
ii) the temperature change for every kilometer from the surface,
From the equation;
y = 23 - 5x
we take, y to be 1
Therefore;
1 = 23 -5x , subtracting 23 on both sides we get
-22 = -5x
x = -22/-5
= 4.4° C
