in a household, a business is run for an average of 6 hours per day. the total power consumed by a computer and its printer is 230 watts. in addition, a 100-w light bulb runs during the same 6 hours. if their utility charges 11.75 cents per kwh, how much do the owners pay every 30-days?
Answers
The amount that the owners will pay every 30 days is $6.98.
The total electricity consumed per hour equals power consumed by computers and printers plus light.The total electricity consumed per hour is 230 watts plus 100 watts.The total electricity consumed per hour equals 330 watts per hour.The total monthly electricity consumption equals total monthly electricity consumption * 6 hours * 30 daysThe total electricity consumed per month equals 330 watts x 6 hours x 30 days.The total electricity consumed is 59,400 wattsThe total electricity consumed is 59.4 kwhThe monthly electric bill equals the total electricity consumed multiplied by the utility charges per kwh.The monthly electric bill equals 59.4 kwh x 11.75 cents.The monthly electric bill is 697.95 cents.The monthly electric bill is $6.98.Therefore, the amount that the owners will pay every 30 days is $6.98.To learn more about power, visit :

Calculate the size of angle a when two known angles are 80 degrees and 30 degrees
Answers
70° is the angle.
every triangle has a total of 180°, therefore 180-80-30=70°
Angle size calculation refers to the use of geometrical laws and invariants to find out how many degrees an angle is. Therefore, it is different from angle size measurement, which includes the use of a protractor or other tools to come up with the result. Calculating an angle's size demands knowledge of complementary, supplementary, and adjacent angles, as well as the properties of geometric shapes.
Subtract the given supplementary angle (its value in degrees) from 180 to calculate the size of the angle in question. Supplementary angles, or straight angles, are those whose sum adds up to 180 degrees.
Repeat the process, this time subtracting the given angle from 90, to calculate the size of an unknown complementary angle. Complementary angles, or right angles, are those summing up to 90 degrees.

Answer:
[tex]x=31.8[/tex]
Step-by-step explanation:
Use the trigonometry ratios to find x. The cosine ratio is used when you are given the side adjacent to the angle and the hypotenuse (the hypotenuse is never considered the adjacent side):
[tex]cosineX=\frac{adjacent}{hypotenuse}[/tex]
Insert the values:
[tex]cos51=\frac{20}{x}[/tex]
Solve for x. Multiply both sides by x:
[tex]x(cos51)=x(\frac{20}{x})\\\\x*cos51=20[/tex]
Isolate the variable. Divide both sides by cos51:
[tex]\frac{x*cos51}{cos51} =\frac{20}{cos51} \\\\x=\frac{20}{cos51} \\\\[/tex]
Insert the value into a calculator to be simplified:
[tex]x=31.78[/tex]

Which system of equations models this situation if d represents the number of cookies Duc baked and h represents the number of cookies Hue baked?
d=2h+10
d=80−h
h=2d−10
d+h=80
d=2h−10
d+h=80
h=2d+10
h=80−d
Answers
Answer: I believe the answer is C
The system of linear equations that represents the given situation is (d + h = 80) and (d = 2h - 10) and this can be determined by using the given data.
Given :
Duc and Hue baked cookies to help with their community's fundraiser. Duc baked 10 less than twice the number of cookies Hue baked. Together they baked 80 cookies.The following steps can be used in order to determine the system of equations models given situation:
Step 1 - Let the total number of cookies Duc baked be 'd' and the total number of cookies Hue baked be 'h'.
Step 2 - The linear equation that represents the total number of cookies Hue and Duc baked is:
d + h = 80
d = 80 - h --- (1)
Step 3 - The linear equation that represents that Duc baked 10 less than twice the number of cookies Hue baked is:
d = 2h - 10 --- (2)
Step 4 - Substitute the value of 'd' in equation (2).
2h - 10 = 80 - h
Step 5 - Simplify the above expression.
3h = 90
h = 30 cookies
Step 6 - Substitute the value of 'h' in equation (1).
d = 80 - 30
d = 50 cookies
Therefore, the correct option is C).

Step-by-step explanation:
7/8 - 1/2 = ?
First, we find the Least Common Denominator and rewrite the fractions with the common denominator.
(7/8 × 1/1) - (1/2 × 4/4)
= 7/8 - 4/8 = ?
Now that the denominators are the same, we can subtract the numerators.
7-4/8 = 3/8
This fraction can't be reduced since it is already in its simplest form. Therefore, 7/8 - 1/2 = 3/8

Answers
Division is one of the four fundamental arithmetic operations. The number of days this cat food will last is 14 days.
What is Division?Division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.
Given that each cat eats 1/4 of a tin of cat food each day. Therefore, the amount of food that two cats will eat in a day is,
= 2 × 1/4 of a tin of cat food each day
= 1/2 of a tin of cat food each day
Further, it is given that Sally buys 7 tins of cat food. Therefore, the number of days this cat food will last is,
= Total cat food / Cat food needed in a day
= 7tin of cat food / 1/2 of a tin of cat food each day
= 14 days
Hence, the number of days this cat food will last is 14 days.

Given f(x) = 3x + 2 andg(x) = -2x - 4, find h(x) = f(x) - g(x).
Answers
Answer:
h(x) = 5x+6
Step-by-step explanation:
h(x) = f(x) - g(x)
h(x) = 3x+2 - (-2x-4)
h(x) = 3x+2 + 2x+4
h(x) = 5x+6
All we need to do is plug in the equations for f(x) and g(x) into h(x)
Let's do it
f(x) = 3x + 2 and g(x) = -2x -4
h(x) = f(x) - g(x)
h(x) = (3x + 2) - (-2x - 4)
Combine like terms
(3x) - (-2x) → 3x + 2x → 5x
(+2) - (-4) → 2 + 4 → 6
Let's put them together
h(x) = 5x + 6

Kendal bought x boxes of cookies to bring to a party. Each boxes contain 12 cookies. She decided to keep 2 boxes for herself. She brings 60 cookies to the party. What equation can be use to find the number of boxes, x kendal bought
Answers
Answer:
7 boxes
Step-by-step explanation:
Let x represent the amount of cookies that was brought to the party by Kendall
Each box contain 12 cookies
= 12 × x
= 12x
Kendall keeps 2 boxes for herself
= 12 × 2
= 24
Kendall has 60 cookies which she took to the party
Therefore the question can be represented as follows
12x = 24+60
12x= 84
Divide both sides by the coefficient of x which is 12
12x/12= 84/12
x= 7
Hence Kendall brought 7 boxes

Use the number line to add −3/5 and 1 1/4.
Answers
Answer:
13/20
Step-by-step explanation:
You can write 1 1/4 as 5/4. Any fraction that has the same number in the numerator and the denominator equals 1. For example 4/4 = 1, 20/20 =1, 5/5 = 1 and so on.
I can rewrite 1 1/4 as 4/4 + 1/4 = 5/4
Now we want to add -3/5 and 5/4. We need a common denominator because the pieces of the fractions are not equal. The smallest number that 5 and 4 will go into is 20. Si U an going to write the two fractions with 20 as the denominator.
-3/5 = -12/20 I multiplied the top and the bottom of -3/5 with 4.
5/4 = 25/20 I multiplied the top and the bottom of 5/4 by 5
-12/20 + 25/20 = 13/20

thrown a certain number of feet.
What is the height of the rock at 5 seconds?

Answer:
h'(t)=88
Step-by-step explanation:
h'(t)=d/dt (-16t x 2 + 120t + 10
h'(t)=d/dt (-32t + 120t + 10)
h'(t)=d/dt (88t + 10)
h'(t)=d/dt (88t) + d/dt (10)
h'(t)=88 + 0
