ok!1 so then eat balls. 40㏑≡Val's whole-house central air conditioner uses 3,500 watts when running. Val runs the AC 5 hours per summer day. Electricity costs (10 cents)/(1 kilowatt-hour). How much does Val's AC cost to run for a summer month of 30 days?
Answer:
$52.50.
Step-by-step explanation:
Since Val's air conditioner uses 3,500 watts when running, and that Val uses it for 5 hours during summer days, spending 10 cents per kilowatt hour, determining how much money Val will spend during a 30-day summer must be done the following calculation:
3,500 watts = 3.5 kilowatts
3.5 kilowatts per hour = 35 cents
35 cents x 5 hours = 175 cents per day
175 cents per day x 30 days = 5250 cents per month
5250/100 = X
52.5 = X
Thus, during 30 days of summer, Val will spend $ 52.50 on electricity from the use of his air conditionier.

Mariam has 126 pieces of chocolate and 16 pieces of hard candy. Her sister has
87 pieces of chocolate and 38 pieces of hard candy. How many pieces of
chocolate do they have in total? *
Answer:
The answer is 213.
Step-by-step explanation:
The question states "how many pieces of chocolate." Not "How much candy and chocolate in total." Therefore all I have to do is 126 (Mariams chocolate count) + 87 (Her sisters choclate count).
Good luck, I hope this helped!!

Select all statements that show correct reasoning for finding 15 divided 2/9
Answer:
B and D
Step-by-step explanation:
If you are dividing by 2/9, that means you are multiplying by 9/2.
This can be split into multiplying by 9 and then dividing by 2, or multiplying by 9 and multiplying by 1/2.
Therefore, B and D work
In Omak the sales tax is 8.4%. What is the total cost including tax Aakel spent on a $48 purchase?
Answer:
$52.03
Step-by-step explanation:
1. Approach
To solve this problem, first one needs to calculate the sales tax, then one must add that to the amount spent on the purchase. To calculate sales tax, one must convert the percent to decimal form, this can be done by dividing the percent by 100. Then one will multiply the decimal by the amount spent.
2. Find the tax
As states above; to calculate sales tax, one must convert the percent to decimal form, this can be done by dividing the percent by 100. Then one will multiply the decimal by the amount spent.
a. convert percent to decimal
8.4 / 100 = 0.084
b. multiply the decimal by the amount spent
48 * 0.084 = 4.032
The amount spent on sales tax is, $4.032
3. Find the total amount spent
Now all one has to do is add the amount spent in tax by the amount spent on the purchase.
48 + 4.032 = 52.032
Since money is only spent rounded to the second decimal point, one has to round the number;
52.03
Select all the equations that are true when x is -4.
-8 = 2x
-12 = x• -3
- 12 = x+x+x
x + 4 = -8
x2=-16
Answer:
-8=2x and -12=x+x+x
Step-by-step explanation:
When x is -4
1). 2(-4) = -8
2). -4.-3= 12
3). (-4)+(-4)+(-4)= -12
4). -4+4= 0
5). -4²= -16
For the last equation, if the -4² was in a bracket then the answer would be 16 because (-²) would give +ABCDE is a pentagon. AM is the line of symmetry. How can you find all the inner angles?

given h(x) =3x-4 find x if h(x) =17
Answer:
x=7
Step-by-step explanation:
h(x) = 17 so you would input 17 for h(x). The equation should look like this. 17= 3x-4. Add 4 to both sides changing the equation to 21 = 3x. Finally divide both side by 3 and you should get x = 7.

In a study published in the July 4, 2007, issue of the Journal of the American Medical Association, researchers investigated whether small doses of dark chocolate can reduce blood pressure for people who suffer from mild cases of high blood pressure. They recruited 44 German adults who were otherwise healthy except for mild cases of high blood pressure. These subjects were randomly assigned to either a dark chocolate group or a white chocolate group, and all subjects were instructed to eat one square portion of a chocolate bar (containing about 30 calories) every day for 18 weeks. They were also instructed not to eat any other cocoa products. Each subject had his/her blood pressure recorded at the beginning and end of the study, with the reduction in blood pressure calculated. It turned out that those in the dark chocolate group had an average reduction of about 3 points in systolic blood pressure, compared to a 0 point reduction on average in the white chocolate group.
Identify the response variable in this study, and classify it as categorical or quantitative.
Answer:
Change in blood pressure ;
Quantitative
Step-by-step explanation:
The response variable also called the predicted variable is the measured variable whose out one depends or relies on the value of the independent or predictor variable. In the scenario above, the measured variable is the change in blood pressure which could be caused by consumption of a certain color of chocolate. The type of chocolate consumed by the subjects (dark or white) is the independent or predictor variable which is expected to effect a change in blood pressure (predicted or measured variable).
Blood pressure change is measured using devices which output numeric values signifying the blood pressure value. This numeric characteristics makes blood pressure change a quantitative variable
From the top of a 178-ft lighthouse, the angle of depression to a ship in the
ocean is 28º. How far is the ship from the base of the lighthouse?
9514 1404 393
Answer:
335 ft
Step-by-step explanation:
The relationship between distances and the angle is ...
Tan = Opposite/Adjacent
tan(28°) = (lighthouse height)/(distance to ship)
distance to ship = (178 ft)/tan(28°) ≈ 334.77 ft
The ship is about 335 ft from the base of the lighthouse.

Answer:
7:12
Step-by-step explanation:
21 and 36 are both multiples of 3.
3 times 7 is 21, and 3 times 12 is 36.
Now, this ratio becomes: 3 x 7 : 3 x 12
Dividing by 3 on both sides,, we have: 7:12. The ratio 7:12 can't be simplified further, so that's the answer.
Let me know if this helps!

Step-by-step explanation:
Three sailors weremarooned on a deserted island that was also inhabited by a band ofmonkeys. The sailors worked all day to collect coconuts but weretoo tired that night to count them. They agreed to divide them upequally the next morning.
During the night, one sailor woke up and decided to get his share.He found that he could make three equal piles, with one coconutleft over, which he threw to the monkeys. Thereupon, he had his ownshare and left the remainder in a single pile.
Later that night, the second sailor awoke, and, likewise, decidedto get his share of coconuts. He also was able to make three piles,with one coconut left, which he threw to the monkeys.
Somewhat later, the third sailor awoke and did exactly the samething with the remaining coconuts.
In the morning, all three sailors noticed that the pile wasconsiderably smaller, but each thought that he knew why and saidnothing. When they then divided the remaining coconuts equally,each sailor received seven and one was left over, which they threwto the monkeys.
How manycoconuts were in the originalpile?
Answer:
x = 690
Step-by-step explanation:
Let´s call x the number of coconuts at night ( at the original pile )
Then the first sailor took x/3 threw 1 to monkeys, therefore, number 1 sailor used x/3 + 1 and left
x - ( x/3 - 1 ) = (3x - x - 3 )/3 = ( 2x - 3 )/3
Evaluating the second sailor
He took [ ( 2x - 3 )/3]/3 ] threw 1 to monkeys
[ ( 2x - 3 )/3]/3 ] + 1 = ( 2x + 24 ) / 9
The third took
[( 2x + 24 ) / 9] /3 and threw 1 to monkeys
{ [( 2x + 24 ) / 9] /3 } + 1 = (2x + 51 )/27
Finally they divided the pile each one of them got 7 and threw 1 to monkeys
The resulting equation is:
( 2x - 3 )/3 + ( 2x + 24 ) / 9 + (2x + 51 )/27 + 21 + 1 = x
Solving for x
18x - 27 + 6x + 72 + 2x + 51 + 594 = 27x
-x = - 690
x = 690
