A device is rated at 1,100 watts.what current is required if it is operated at 110 volts?

WINSTONCH [101]

1 ) Watts =E * I = 110 * 5 = 550 watts =.55 KW

2) I = Watts / e = 1100 / 110 = 10 amperes

3) 1 horsepower = 33000 ft/lbs per minute

HP = ( 2000 * 1000) / (33000 *4) = 15.1515 hp

4) cost = (10 * 100 / 1000) *11 * $0.10 = $1.10

5) This answer will be incorrect because you have not stated the power factor of the motor.

va = I * E = 7.5 * 240 = 1800

2 hp = 2 * 746 watts = 1492 watts

If the motor had a 1.0 power factor (it doesn't) the efficiency would be

efficiency = output / input = 1492 / 1800 = 82.888 %

6) I = watts / E =1000 / 120 = 8.333 amps

7) 1 = watts / E = 1000 / 240 = 4.1616

8) Kw-hr = (2 * 24 * 365 ) / 1000 = 17.52

cost = kw-hr * $0.03 = 17.52 * $0.03 = $0.5256

9) efficiency = (115 * 240) / (2400 * 12) = 95.8333 %

10) KW = (I^2 * R) / 1000 = (20^2 * 5) / 1000 = 2

Daine simplified the expression below.

alisha [4.7K]

Answer:

Option (b).

Step-by-step explanation:

Given expression is :

8(1 + 2i) – (7 – 3i)

Using distributive property :

8+16i-7+3i

Taking like terms together,

1+19i

(1+19i) is the simplified expression for the given expression. He did not apply distributive property correctly for 8(1 + 2i). He forgets to multiply 8 with 2i.

Sabrina borrowed $350000 with a 0.5% interest rate from Bank of America to buy a new condo in orange beach how did it take Sabri

n200080 [17]

Answer:

t = 2466.67 years (about 2466 years 8 months)

Step-by-step explanation:

Given: Total P+I (A) = $350000, Principal (P) = $26250, Rate (R) = 0.5%

To find: How long did it take Sabrina to pay if the loan if she ended up pay $26250 interest?

Formula: $t = (1/r)(A/P - 1)$

Solution: To calculate your interest rate, you need to know the interest formula I/Pt = r to get your rate

First, converting R percent to r a decimal

r = R/100 = $\frac{0.5 percent}{100}$ = 0.005 per year,

then, solving our equation

t = (1/0.005)((350000/26250) - 1) = 2466.67

t = 2466.67 years

Therefore, it will take Sabrina 2466.67 years (about 2466 years 8 months) to pay off the loan.
