Answer:
3.5 Gallons Per Minute or 3.5m
Step-by-step explanation:
Since there is 10.5 Gallons in 3 minutes, do
10.5/3 = <u>3.5</u>

Answer:
a + 20 = 7*12 (multiplied both sides by 12)
a + 20 = 84 (calculated 7*12)
a = 84 - 20 (subtracted 20 on both sides)
a = 64 (calculated 84-20)
Answer:
![\%Change = 8.8\%](https://tex.z-dn.net/?f=%5C%25Change%20%3D%208.8%5C%25)
Step-by-step explanation:
Given
![Initial = 51\ cents](https://tex.z-dn.net/?f=Initial%20%3D%2051%5C%20cents)
![Final = 55.5\ cents](https://tex.z-dn.net/?f=Final%20%3D%2055.5%5C%20cents)
Required
Determine the percentage change
Percentage change is calculated as;
![\%Change = \frac{Final - Initial}{Initial} * 100\%](https://tex.z-dn.net/?f=%5C%25Change%20%3D%20%5Cfrac%7BFinal%20-%20Initial%7D%7BInitial%7D%20%2A%20100%5C%25)
![\%Change = \frac{55.5 - 51 }{51 } * 100\%](https://tex.z-dn.net/?f=%5C%25Change%20%3D%20%5Cfrac%7B55.5%20-%2051%20%7D%7B51%20%7D%20%2A%20100%5C%25)
![\%Change = \frac{4.5}{51} * 100\%](https://tex.z-dn.net/?f=%5C%25Change%20%3D%20%5Cfrac%7B4.5%7D%7B51%7D%20%2A%20100%5C%25)
![\%Change = \frac{4.5* 100\%}{51}](https://tex.z-dn.net/?f=%5C%25Change%20%3D%20%5Cfrac%7B4.5%2A%20100%5C%25%7D%7B51%7D)
![\%Change = \frac{450\%}{51}](https://tex.z-dn.net/?f=%5C%25Change%20%3D%20%5Cfrac%7B450%5C%25%7D%7B51%7D)
![\%Change = 8.8\%](https://tex.z-dn.net/?f=%5C%25Change%20%3D%208.8%5C%25)
<em>Hence, the percentage change is approximately 8.8%</em>
Answer:
x = 12
(2x + 1)° = 25°
(5x + 5)° = 65°
Step-by-step explanation:
By the property of a triangle,
Sum of all angles of a triangle is 180°
In the given right triangle,
(2x + 1)° + 90° + (5x + 5)°= 180°
7x + 96 = 180
7x = 180 - 96
x = ![\frac{84}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B84%7D%7B7%7D)
x = 12
Angle (2x + 1)° = 2(12) + 1 = 25°
Angle (5x + 5)° = 5(12) + 5 = 65°
Therefore, all three angles of the right triangle are 25°, 90° and 65°.
