AURORKA [14]3 years ago

Answer:

960 Watt

Step-by-step explanation:

Power consumed by light bulb in 3 days and 18 hours = 3600 Watt

number of hours in one day = 24 hours

total number of hours in 3 days and 18 hours = 3*24 + 18 = 90 hours

Power consumed by light bulb in 1 hour = \frac{3600}{90} = 40 Watt

∴ Power consumed by light bulb in 1 day (24 hours) = 40*24 = 960 Watt

18 hours = 18/24  reduces to 3/4 of a day

3/4 = 0.75

so 3600/3.75 = 960 watts per day

snow_tiger [21]
<h3>Answer:  40</h3>

=============================================

Explanation:

Assuming the function is f(x) = 5(2)^x, then we replace every x with 3. Then we use the order of operations PEMDAS to simplify. Or we can use a calculator to simplify in one step.

f(x) = 5(2)^x

f(3) = 5(2)^3

f(3) = 5(8)

f(3) = 40

In the right triangle below, tanA = 0.45. What is the approximate length of AB?
kodGreya [7K]

Answer with Step-by-step explanation:

We are given that:

tanA = 0.45

tanA= \dfrac{Perpendicular}{Base}

      =  \dfrac{BC}{AC}

⇒  \dfrac{BC}{AC}=0.45

⇒  \dfrac{9}{AC}=\dfrac{45}{100}

⇒  \dfrac{9}{AC}=\dfrac{9}{20}

⇒  AC= 20

Hence, by pythagoras theorem

AB²=AC²+BC²

AB²=20²+9²

AB²=481

⇒  AB=21.9 units

Hence,  the approximate length of AB is:

22 units

1. A family is building a circular fountain in the backyard. The yard is rectangular and measures 10x by 15x and the fountain is
sp2606 [1]
1. The remaing area of the yard will be found as follows:
Area of the yard

A1=length*width=10x*15x=150x^2 yd^2

area of the fountain
A2=πr²
A2=π(4x)²
=50.266x^2

The remaining area will be:
A=150x^2-50.266x^2
A=99.735x^2 yd^2


2] Area left for bleachers, restrooms and other parts of the stadium will be as follows:
Area of the lot is:
A1=length*width
A1=8x×12x= 96x^2 

Area of the field
A2=length×width
A2=3x×6x=18x^2

Hence the remaining area will be:
A1-A2
=96x^2-18x^2
=78x^2 sq. units
