The air plane is rising so the change in elevation is +1000 feet. The temp dropped and is -20 degrees fahrenheit.
1 degree per 50 ft
For every 1,000 feet that it climbs, the outside temperature drops 20 ... What is the rate of temperature change in degrees Fahrenheit per foot.
Answer:
Step-by-step explanation:
First move the numbers from the Left hand side to the right hand side. To do so, as it is an equation i.e. both sides must remain the same, you add or subtract the same numbers on both side.
5 + 13k - 61 = 17
5 - 5 + 13k - 61 + 61 = 17 - 5 + 61
13k = 73
k = 73 / 13
k = 5.62 (approximately)
Answer:
There would be 30 nickels and 78 quarters.
Step-by-step explanation:
To find this, start by creating a system of equations in which x is the number of nickels and y is the number of quarters. Make the first equation the total number of coins.
x + y = 108
Make the second equation based on the value.
.05x + .25y = 21
Now multiply the second equation by -4 and add together to get the y value to cancel.
x + y = 108
-.2x - y = -84
--------------------
.8x = 24
x = 30
Now use this value to find y.
x + y = 108
30 + y = 108
y = 78
The answer is 3.14 I learned this in school
