Answer:

[tex]P=0.27\,\,watts[/tex]

Step-by-step explanation:

Consider the formula: [tex]I=PR[/tex]

Here, [tex]I[/tex] represents the current (measured in amps), P represents power (measured in watts), and R represents resistance (measured in ohms).

Resistance = 15 ohms

Current = 4 amps

To find electrical power drawn by a device, put [tex]R=15\,,\,I=4[/tex]

So,

[tex]4=15P\\P=\frac{4}{15}=0.27\,\,watts[/tex]

985,600

Step-by-step explanation:

hope that helps

Answer:

It would be A.

Step-by-step explanation:

You can simply add the numbers to coordinates to see if matches.

For example, if you add the x + 2 to -3 and 2, its -1 and 4. Then if you add y+3 to -1 and 1, it's 2 and 4. I hope that makes sense :)

Welcome to the other MHN solving classes.

Let's see what to do ......

_________________________________

Step (1)

EC bisects BED ;

Thus : BEC = CED

_________________________________

Step (2)

Question told us that CED = 4 x + 1

Thus : BEC = CED = 4 x + 1

_________________________________

Step (3)

AD is a straight line which means its angle size is equal to 180° degrees.

So :

AEB + BEC + CED = 180

( 11x - 12 ) + ( 4x + 1 ) + ( 4x + 1 ) = 180

11x + 4x + 4x - 12 + 1 + 1 = 180

19x - 10 = 180

Plus sides 10

19x - 10 + 10 = 180 + 10

19x = 190

Divided sides by 19

[tex] \frac{19}{19}x = \frac{190}{19} \\ [/tex]

[tex]x = 10[/tex]

So : x = 10°

_________________________________

Step (4)

AEB = 11x - 12

AEB = 11(10) - 12

AEB = 110 - 12

AEB = 98°

******************************************************

BEC = CED = 4x + 1

BEC = CED = 4(10) + 1

BEC = CED = 41°

_________________________________

Step (5)

AEC = AEB + BEC

AEC = 98° + 41°

AEC = 139°

Step-by-step explanation:

a^2+b^2 = c^2

C is the biggest number, so put in all the numbers in the equation then if it's equal then it's a right triangle.

example: 6^2 + 8^2 = 10^2

36 + 64 = 100

100 = 100

this one is a right angle because the two sides is equal to the hypotenuse(largest number).

Answer:

Aren't they equivalent to 5:6?

Step-by-step explanation:

Your situation models to 5x:6x, and no matter what you put as x, it will amount to the ratio of 5:6. It's basically a big fraction, with 5/6 as the simplfication.

Answer:

Step-by-step explanation:

The easiest way to start this is just to multiply the 5 and the 6 by the same thing and see what happens.

Randomly, I will choose 7 because I think today is the 7th.

5*7

====

6*7

35

===

42

I know this is going to seem ridiculous but I'm not going to divide 35/42 by 7.

35 divide by 7 = 5

42 divide by 7 = 6

Just what you started with.

Now a little less obvious, suppose we multiply top and bottom of the ratio by a. a can be anything like (say) the 5th root of 3233

5* a

====

6 * a

Divide the top and bottom by a.

5a divided by a = 5

=======

6a divided by a = 6

So what's the answer? If you've read through this, you'll know that nothing changes.

The answer is the first one.

Answer:

[tex]\text{The reduced fraction is } \frac{2}{3}[/tex]

Step-by-step explanation:

Fraction Reduction

To reduce a fraction, we try to divide both the numerator and denominator by the very same number until no more numbers can be found.

The fraction to reduce is:

[tex]\displaystyle \frac{54}{81}[/tex]

Since the denominator is odd, we cannot divide by 2, but we can divide by 3:

[tex]\displaystyle \frac{54}{81}=\frac{18}{27}[/tex]

We divide by 3 again:

[tex]\displaystyle \frac{18}{27}=\frac{6}{9}[/tex]

We divide by 3 one last time:

[tex]\displaystyle \frac{6}{9}=\frac{2}{3}[/tex]

[tex]\text{The reduced fraction is } \frac{2}{3}[/tex]

Answer:

The answer is Quadrant 1

Answer:

n = 23

Step-by-step explanation:

n - 13 x -6 = -60

distribute:

(n x -6) - (13 x -6) = -60

-6n - (-78) = -60

two negatives in front of a number makes it a positive number

so rewrite -6n + 78 = -60

-6n = -60 - 78

-6n = -138

n = [tex]\frac{-138}{-6}[/tex]

n = 23

Answer:

Cluster Random Sample

Step-by-step explanation:

The operating rooms were divided into (hospital locations) and inspectors sampled every operating room from some of the groups.

Sampling method is the method where the subset of an overall population is selected.

The sampling method used was cluster sampling

From the question, we understand that:

The above illustrates cluster sampling.

This is so because, cluster sampling involves breaking down a population into smaller size.

In this case, the smaller size are the locations that were selected.

There are 25 people in the club.

Step-by-step explanation:

5 X 3 = 15. 5 X 5 = 25

3.5*10^3=3,500

3,500+ 575,900=579,400

The bank vault will hold $575,900 + $3.5 x 10^3 = $579,400 at the end of the business day.

An integer is a number with no decimal or fractional part and it includes negative and positive numbers, including zero.

Now it is given that,

Money in the bank vault at the beginning of the day = $575,900

Money added in the vault at the end of the day = $3.5 x 10^3 = $3,500

Since money is added in the vault thus it is gain.

So, Money added in the vault at the end of the day = + $3,500

Thus, Money at the end of the business day = $575,900 + $3,500 = $579,400

Thus, the bank vault will hold $575,900 + $3.5 x 10^3 = $579,400 at the end of the business day.
