Answer:
D - x=y/12
Step-by-step explanation:
So lets just take one set of data from the table.
This is all we need.
So I am just going to set our values to:
x = 21
y = 252
Now lets plug this into each equation, ands ee if it is accurate or not:
21=12+252
=
21=264
Thats not right! Lets try the next one:
21 = 252/12
=
21 = 21
Thats correct! Lets just try the other ones anyway:
21 = 252 - 12
=
21=240
Thats not right! Lets try the last one:
21 = 12*252
=
21 = 52,424
That is most definatly not right!
So the answer is B, x=y/12
Hope this helps!

Maggie's brother is 7 years younger than twice her age. The sum of their ages is 32.
How old is Maggie?
Maggie is
years old
Answer:
Let M = Maggie's age
B = Brother's age
Then M + B = 32
B = 2M - 7
Then M + 2M - 7 = 32
3M= 39 = 13
M= 13
Maggie is 13.

Which is the most economic way to lessen electric consumption?
a.Use all appliances which are not so important
b.More appliances will be used for relaxation
c.Use only appliances to the most important task in the house
d.Don’t mind the high bill anyway you have have much money to pay for bill
An electric bill shows a previous reading of 2156kwh and a present reading of 2268kwh How many kilowatt-hour was consumed?
a.102kwh
b.112kwh
c.112kwh
d.122kwh
Compute the electrical consumption of Falogme Family if the present reading in their eletric meter is 5623kwh and the previous reading is 5512kwh
a.110kwh
b.111kwh
c.112kwh
d.121kwh
Answer:
1) c. Use only appliances to do the most important task in the house.
2) b. 112kwh
3) b. 111kwh
Step-by-step explanation:
Energy can be defined as the ability (capacity) to do work and it's measured in Joules. The various forms of energy are solar energy, chemical energy, thermal energy, wind energy, nuclear energy, electrical energy, etc.
Power can be defined as the energy required to do work per unit time.
Mathematically, it is given by the formula;
[tex] Power = \frac {Energy}{time} [/tex]
Energy consumption is the total amount of power used by an electronic device per unit time and it's measured in Watt-hour or Kilowatt-hour.
Mathematically, it is given by the formula;
[tex] Energy = power * time [/tex]
Generally, the most economic way to lessen electric consumption is by ensuring only the important electrical appliances are used at all times.
2. Given the following data;
Previous reading = 2156 KWh
Present reading = 2268 KWh
To find how many kilowatt-hour was consumed;
Energy consumption = present reading - previous reading
Energy consumption = 2268 - 2156
Energy consumption = 112 KWh
3. Given the following data;
Previous reading = 5512 KWh
Present reading = 5623 KWh
To find the electrical consumption of Falogme Family;
Electrical consumption = present reading - previous reading
Electrical consumption = 5623 - 5512
Electrical consumption = 111 KWh
find the perimeter of the trapezoid
Answer:
Perimeter you add up all the sides. If it is a horizontal or vertical line, you just write those values for the side lengths. For the slanted one, I would use pythagorean theorem to solve it.
Step-by-step explanation:
If we make a right triangle using vertical and horizontal lines. We will find that a = 6, and b = 12. Find the square root of the sum of a squared plus b squared. That will tell you C. Then add C to the other 3 sides and that will give you the perimeter.
In the diagram below,
Answer:
<H = 40
Step-by-step explanation:
Complementary angles add to 90 degrees
2x+10 + x+20 = 90
Combine like terms
3x+30 = 90
Subtract 30
3x+30 -30 = 90-30
3x = 60
Divide by 3
3x/3 = 60/3
x = 20
<H = x+20 = 20+20 = 40
What is the image of the point(2,-5) after a rotation of 90 degree counterclockwise about the origin
Answer:
(-2,5)
Step-by-step explanation:
When a point is rotated counterclockwise 90 degrees about the origin then the coordinates of the image will be (x,y) → (-y,x).
Here, (5,2)→(-2,5)
Therefore , if (5,2) is rotated counterclockwise 90 degrees about the origin its image will be point (-2,5).
Hence, if (5,2) is rotated counterclockwise 90 degrees about the origin its image will be point (-2,5).

A map has a scale of 1:200000 How far is it from Belfast to Larne in Km if the distance on the map is 7.8cm
Answer:
15.6km
Step-by-step explanation:
Given the map scale 1:200000
1cm on the map represents 200000 cm on ground or in actual distance
Hence, if distance from Belfast to Larne is 7.8vm on map ;
Actual distance will be :
7.8 * 200000 = 1560000 cm
Converting to km :
Recall :
1000 m = 1km
100 cm = 1 m
Hence,
100000 cm = 1km
Therefore, (1560000 / 100000) km
= 15.6km
Hence, distance between Belfast and Larne is 15.6km

Vanessa received a $12,000 loan from the bank to buy a motorcycle. She will repay the loan to the bank with an $300 monthly payment.
Answer:
40 months
Step-by-step explanation:
It will take Vanessa 40 months or 3 years and 4 months to repay the bank their loan amount(without interest ofc).
Answer:
Time = 42 months
Step-by-step explanation:
[tex]Monthly \ payment = [rate + \frac{rate}{(1 + rate)^{month}-1}] \times principal[/tex]
Monthly payment = 300
Principal = 12000
[tex]Rate \% = \frac{300}{12000} \times 100 = \frac{30}{12} = \frac{5}{2} = 2.5[/tex]
Substituting and solving Months = 42 months
HELP ASAP IM BEING TIMEDD
Answer:
53/100
Step-by-step explanation:
First, we convert the fraction to a decimal number by dividing the numerator by the denominator:
8 / 15 = 0.533
There are two parts to the decimal number above:
Integer Part: 0
Fractional Part: 533
Now, we will make the Fractional Part just two digits (nearest hundredth) by using our rounding rules.*
In this case, Rule I applies, so 8/15 (or 0.533) rounded to the nearest hundredth in decimal format is:
0.53
Next, we will make 8/15 rounded to the nearest hundredth in fraction format. Since you can divide our decimal format answer above by 1 and keep the same value, you can make it like this:
0.53 = 0.53/1
Then, we multiply the numerator and denominator by 100 to get rid of the decimal point:
(0.53 x 100) / (1 x 100) = 53/100
That's it. 8/15 rounded to the nearest hundredth is displayed below (simplified if necessary):
53/100
Answer:
53.33% is the correct answer

The yearbook staff receive 75 submissions for yearbook articles. Paul will accept 2/5

Answer:
2/5 of 75 is 30 thats all i have for because i am haveing trouble with the same question
Step-by-step explanation:
the area of a circle is 81 pi m^2. what is the circumference, in meters? express your answer in terms of pi.
============================================================
Explanation:
The area 81pi square meters leads to the radius 9 meters
Use the formula A = pi*r^2 to see why this is the case. You plug in A = 81pi and solve for r to get r = 9.
-----------------
Once you know the radius, you can determine the circumference C
C = 2*pi*r
C = 2*pi*9
C = 2*9*pi
C = 18pi
The circumference is the perimeter, or distance, around the circle.
Which angle is complementary to ∠X?
Answer:
Complementary angles sum to 90°.
∠X has ∠P complementary to it as:
P + X = 90°What is the volume of the cylinder shown? Use 3.14 for pi. 4cm is the radius and 9cm is the height.
Answer:
The formula is 4cm times 9cm which is 36cm. Then times that by pi which is 113.04. The answer is 113.04
Step-by-step explanation:
Answer:
Volume - 452.16 cm
Step-by-step explanation:
First we need to find the area of the circle.
Area of a circle - (3.14)r^2
Insert the radius in the formula -
(3.14) (4)^2
3.14 x 16
50.24 is the area of the circle
Now, we have to multiply this value by the height of the cylinder in order to find the volume.
50.24 x 9 = 452.16 cm

1. Two dice are thrown at the same time . What is the probability that the sum will be 7 or 11 ?
2. A ball is drawn at random from a box containing 6 red balls , 4 white balls and 5 blue balls.
Determine the probability that is red or white.
Answer:
1. 0.2222222
2. .6667
Step-by-step explanation:
for question 1
there can only be 36 outcomes so you find out how many time you could get 7and2 which is 8 from so u write 8.36=.2222
for question 2
divide the outcome by the total out comes example(there are 6 red balls and 4 white out of 15 so you do 10/15=.6667)
Answer:
#1Outcomes with sum of 7:
1 + 6, 2 + 5, 3 + 4, 4 +3. 5 + 2, 6 + 1Outcomes with sum of 11:
5 + 6, 6 + 5Total outcomes:
6*6 = 36Required probability:
P(sum of 7 or 11) = (6 + 2)/36 = 8/36 = 2/9 or 22.22%#2P(red or white) = (6 + 4)/(6 + 4 + 5) = 10/15 = 2/3 or 66.67%plz help me, i need help with this and i dont understand what this means

6) Find the value of x
Answer and Step-by-step explanation:
We are given a linear pair. The angles of a linear pair add up to 180.
To find x, add the two angles together and equal it to 180, then solve for x.
126 + x + 23 = 180
Simplify.
149 + x = 180
Subtract both sides of the equation by 149.
x = 31
x = 31 is the answer.
