Answer:
hey
here is the attachment of your question
Set the two equal to each other and solve for x
-2x+1 = -2x²+1
-2x= -2x²
x=x²
x²-x=0
x(x-1) =0, so x is either 0 or 1
two solutions, namely (0,1) and (1,1)
Volume of the spherical tank will be given by:
V=4/3πr³
thus the volume of the tank will be:
V=4/3×π×(10/2)³=523.59877756~523.6 ft³
Given that 523.6 ft³ can hold 358,000,000 BTUs of propane, the amount that 1 ft³ will be given by:
[total amount]/[total volume]
=358,000,000/523.6
=683,728.0367 BTUs/ft³
=684,000 BTUs/ft³ (in thousand)
Answer:
Step-by-step explanation:
<u>Given</u>
- The dimensions of the lot are (6+x) feet and (6−x) feet
- The dimensions of the house to be (2+x) feet and (2−x) feet
Area of the yard = Area of the lot - Area of the house
<u>Area of the yard:</u>
- (6 + x)(6 - x) - (2 + x)(2 - x) =
- 36 - x² - 4 + x² =
- 32 square feet
<u>If the house is extended, then the area of the yard will change as:</u>
- (6 + x)(6 - x) - (4 + x)(4 - x) =
- 36 - x² - 16 + x² =
- 20 square feet
Answer:
1 Bag = 12.3 Ounces
5 Bags = 61.5 Ounces
123 Ounces = 10 Bags
Step-by-step explanation:
24.6 divided by 2 is 12.3.
12.3 times 5 is 61.5
61.5 times 2 is 123.
