Answer:

140 ft²

Step-by-step explanation:

The figure is composed of a rectangle and a triangle

note triangle has a base = 16 - 12 = 4 ft

Area = area of rectangle + area of triangle

        = (16 × 8) + (\frac{1}{2} × 4 × 6)

        = 128 + 12

        = 140 ft²

The sum of a whole number and twice the square of the number is 10. Find the number.
sveticcg [70]

Answer:

x = \frac{10}{1 + 2x}

Step-by-step explanation:

Let the number be x

x + 2x² = 10

Factorize x + 2x²

x(1 + 2x) = 10

Divide both sides by (1 + 2x)

x = \frac{10}{1 + 2x}

Jim is showing his work in simplifying (−8.5 + 6.1) − 1.3.
dexar [7]

9514 1404 393

Answer:

  In step 4, Jim's answer is incorrect.

Step-by-step explanation:

In step 1, Jim swaps the order of addends using the commutative property of addition.

In step 2, Jim uses the distributive property to factor -1 from the final two terms. (The associative property lets Jim move parentheses.)

  6.1 +(-8.5 -1.3) . . . associative property

  6.1 +(-1)(8.5 +1.3) . . . distributive property

In step 3, Jim has used the properties of real numbers to form the sum of two of them.

In step 4, Jim wrote an answer of 1.1, when the answer should have been -3.7. Jim's answer is incorrect.

__

The descriptive statements about steps 2 and 4 are both true.

OverLord2011 [107]

Answer:

  ai) 73000 gal/yr

  aii) $730 per year

  b) 1000 days

Step-by-step explanation:

ai) The water usage per day is ...

  (4 showers/day)(10 min/shower)(5 gal/min) = 200 gal/day

Then the usage per year is ...

 (200 gal/day)(365 days/yr) = 73,000 gal/yr

__

aii) The cost of electricity is the cost of heating half the water usage, so is ...

  (0.20 kWh/gal)(1/2)(73,000 gal/yr)($0.10/kWh) = $730/yr

__

b) The current daily cost of electricity for heating water is ...

  ($730/yr)/(365 days/yr) = $2/day

If the cost is cut in half, it will be $1 per day. That means the savings is $1 per day, so it will take 1000 days to recover the $1000 initial cost. (Effectively, the average cost for the first 1000 days is the same as if the water heater had not been replaced.)
