Answer:
1222 ft²
Step-by-step explanation:
- 11*19*2=418
- 11*9*2=198
- 19*9*2 - 10*9=252
- 13*9*2=234
- 1/2*10*12*2=120
418+198+252+234+120=1222 ft²
Answer:
40 meters
Step-by-step explanation:
x=4
3x-4=12-4
2x-3=8-3
12-4=8
8-3=5
8x5=40
Answer:
SteLet a = short leg of the right triangle, b = the longer leg, and c = the hypotenuse.
The longer leg of a right triangle is 4inches longer than the shorter leg: b = a + 4
The hypotenuse is 8inches longer than the shorter leg: c = a + 8
Use the Pythagorean Theorem:
a2 + b2 = c2
a2 + (a+4)2 = (a+8)2
a2 + a2 + 8a + 16 = a2 + 16a + 64
a2 - 8a - 48 = 0
Factors to:
(a-12)(a+4) = 0
a = 12, -4
Since we can't have a side of -4, a = 12
Shorter Leg = 12 inches
Longer Leg = 12 + 4 = 16 inches
Hypotenuse = 12 + 8 = 20 inches
Answer:
Total amount of pizzas: 6
Total gallons of root beer: 4
Step-by-step explanation:
In 18 hours this is what each one of them could make. (Assuming that none of them can make pizza and brew at the same time)
Pat takes 6h to brew one gallon and make one pizza. So, 18h divided by 6, gives us a total of 3 gallons of beer and 3 pizzas.
Kris takes 10h to brew one gallon and make one pizza. So, 18h divided by 10 gives us 1 and 8h left that Kris could use to make another 2 pizzas. The total for Kris would be 1 gallons of beer and 3 pizzas.
Combined, the totals are:
4 gallons of root beer (3 Pat and 1 Kris) and 6 pizzas (3 each).
Answer: B.
Step-by-step explanation:
We know that,
Then,
