Answer:

105°

Step-by-step explanation:

since its a straight line then put it equal to 180. First we add and then subtract from 180, like this.

52+23=75

180-75=105

Answer:

It costs Laura $ 5,184.86 to heat her house one day.

A 75 watt lightbulb should be around 222 hours to consume a dollar in electricity.

Step-by-step explanation:

Given that a kilowatt hour means 1 kilowatt of electricity used continuously for 1 hr, and the electric utility company in Laura's town charges $ 0.06001 for each kilowatt hour used, and Laura heats her house with three electric heaters that each use 1200 watts, to determine how much does it cost to heat a house in one day and how many hours would a 75 watt lightbulb have to stay on to result in one dollar for electricity charges the following calculations must be performed:

(3 x 1200 x 24) x 0.06001 = X

(3600 x 24) x 0.06001 = X

86400 x 0.06001 = X

5,184.86 = X

Therefore, it costs Laura $ 5,184.86 to heat her house one day.

1 watt = 0.001 kilowatt

75 watt = 0.075 kilowatt

1 / 0.075 = 13.333

1 / 0.06001 = 16,663

13,333 x 16,663 = 222.18

Therefore, a 75 watt lightbulb should be around 222 hours to consume a dollar in electricity.

Answer:

x = 12

Step-by-step explanation:

m<BCF and m<CFE are same-side interior angles.

Same-side interior angles are supplementary. This implies that:

m<CFE + m<BCF = 180°

where,

m<CFE = 11x°

m<BCF = 4x°

Plug in the values

11x + 4x = 180

15x = 180

x = 180/15

x = 12

Part 1 :

☃ [tex] \underline{ \large{ \sf{Vertical \: Line \: Test}}} : [/tex] ⇾ All the relations are not functions. We can determine ( identify ) whether a relation is function or not by drawing a vertical line intersecting the graph of the relation. This is called the vertical line test.

( See the attached picture )

Part 2 :

☂ The set of all the images of the elements of domain under the function ' f ' is called the range of a function. In other words , the set of second components of a function is called range. We are given the function :

The above numbers [ in bold ] are the range of given function. Now, If we arrange these numbers in ascending order, we get ( -9 , -3 , 0 , 5 , 7 ).

Hence , Choice B [ {y | y = –9, –3, 0, 5, 7} ] is correct.

Sample Response:

The vertical line test is a way to determine if a relation is a function. This test determines if one input has exactly one output on the graph. If any vertical line passes through more than one point on the graph, then the relation is not a function because two different outputs have the same input.

the answer is 11.3

Answer:

x=31

Step-by-step explanation:

we need to isolate x so we put 48 t the other side to make -x=17-48

we do 17-48 =-31 so -x=-31

x=31

Answer:

X>30

Step-by-step explanation:

Well the brackets or parethesis or absolutvalue sign thingy doens’t ,matter. Out of all the signs that won’t do anything at all.

Solve it normally

add 28 on both sides

2x>60

60/2=30

x>30

Answer:

Answer should be...

2x - 28 > 32

ADD BY BOTH SIDES (NON-VARIABLES)

    + 28  + 28

2x > 60

DIVIDE BY VARIABLE NUMBER (2)

2x/2 > 60/2

x > 30

Answer:

The number decreases

Step-by-step explanation:

The number decreases because if it's on -2 the way it will increase will be on going forward with no negatives

Answer:

If the radius of the circle is 7cm . Its area is 154cm square.

Answer:

Final Answer 25.12

Step-by-step explanation:

This is very simple you can use two formulas to find the circumfrence of the circle. You can either use C=2πr or C=πd.

For this problem you will be using C=2πr since r is radius and the radius is 4.

C=2*3.14*4

C=6.28*4

C=25.12

Hope this helps.

Answer:

The difference of the original two-digit number and the number with reversed digits is 18.

Step-by-step explanation:

Since it's a two digit number, let x represent the tens digit and let y represent the units digit.

Thus, the original two digit number is;

10x + y.

The reverse two digit number is;

10y + x.

We are told that five times the sum of the digits of the two-digit number is 13 less than the original number.

Thus;

5(x + y) = (10x + y) - 13

Multiplying out the bracket gives;

5x + 5y = 10x + y - 13

Rearranging gives;

10x - 5x + y - 5y = 13

5x - 4y = 13 - - - - (3)

Also,we are told that, four times the sum of its two digits is 21 less than the reversed two-digit number. Thus;

4(x + y) = (10y + x) - 21 - - - (4)

Simplifying gives;

4x + 4y = 10y + x - 21

>> 10y - 4y - 4x + x = 21

>> 6y - 3x = 21 - - - (4)

Solving eq(3) and (4) simultaneously gives;

x = 5 and y = 3

Thus,

Original number = 53

Reversed number = 35

Difference between original and reversed number = 53 - 35 = 18

Answer:

961.625 ≈ 962

Step-by-step explanation:

(A WHEEL IS A CIRCLE!)

To find the area of a circle, you must multiply the radius by itself twice, then, multiply the product by pi (radius x radius x pi).

Here, only the diameter is shown.

To find the radius, we must divide the diameter by 2.

35 / 2 = 17.5

17.5 is the radius.

17.5 x 17.5 = 306.25.

**3.14 is commonly used for pi**

Lastly, we multiply the product by pi.

306.25 x 3.14 = 961.625

961.625 rounded to the nearest foot is 962.

Therefore, the area of the wheel is 962 feet.
