If two radio stations start conmercials at 10am, when will the stations have commercials at the same time? One station plays every 12 minutes the other every 8 minutes.
Answers
Answer: If two radio stations start commercials at 10 AM , then at 10:24 AM the stations will have commercials.
Step-by-step explanation:
Given: One station plays every 12 minutes the other every 8 minutes.
The minimum time at which both stations have commercials = lcm (12 and 8 )
12 = 2 x 2 x 3
8 = 2 x 2 x 2
LCM( 12 and 8)= 2 x 2 x 2 x 3 = 24
The minimum time at which both stations have commercials = 24 minutes

What is the measure of the third angle
Answers
58
a right triangle is 90 degrees so you subtract 32 from 90 to find the remainder
Answer:
The third angle is 58 degrees
Step-by-step explanation:
In a triangle all three angles add up to 180 degrees. If you know two sides, add them up then subtract the sum from 180. This will leave you with the last angle measurement.
In a right triangle we always know there is one angle that has a measure of 90 degrees. So now we know two angles 90 and 32.
90 + 32 = 122
180 - 122 = 58

11. The price of a bottle of water at a store decreases from $1.65 to $1.40. Rounded to the nearest
tenth of a percent, what is the percent decrease in the price of the bottle of water?
A. 15.2%
B. 17.9%
C. 45.9%
D. 54.1%
Answers
Answer:
A. 15.2%
Step-by-step explanation:
Subtract the new price from the old one to find the dollar amount that the water bottle price was reduced.
[tex]1.65-1.40=0.25[/tex]
The price was reduced by 25 cents, but we need to find the percentage. To do that, we divide the price reduction by the original price.
[tex]0.25/1.65=0.152[/tex]
And then move the decimal place over two spots (multiply by 100)
15.2
Percent decrease in the price of the bottle of water is 15.2% (Approx.)
Given that;Older price of bottle = $1.65
New price of bottle = $1.40
Find:Percent decrease in the price of the bottle of water
Computation:Percent decrease in the price of the bottle of water = [(1.65 - 1.40) / 1.65]100
Percent decrease in the price of the bottle of water = [(0.25) / 1.65]100
Percent decrease in the price of the bottle of water = [(0.25) / 1.65]100
Percent decrease in the price of the bottle of water = 15.2% (Approx.)

Malcolm is filling bags with rice. He starts with a 5 1/4 pound container of rice and fills each bag with 5/8 pound of rice. How many bags of rice can malcolm fill??
Answers
Answer:
part 1: Divide 5 1/4 pound by 5/8 pound
part 2: 8 bags
part 3: 2/5 of another bag
Step-by-step explanation:
total number of bags that can be filled equals total rice divided by the amount of rice per bag
=5 1/4 divided by 5/8
=(21/4)/(5/8) turn the mixed number into improper fraction
=(42/8)(5/8) common denominator
=42/5
=8.4 bags, but can only fully fill 8 bags
2/8 pounds of rice are left over after filling 8 bags, and 2/8 pounds is equal to
2/5 of another bag
(2/8)/(5/8)
=2/5 simplify

In fixed deposit, a bank gives 10% interest compounded annually for senior citizens. How many complete years will it take for a sum of money to be more than double.
Answers
Answer: 8 years
Step-by-step explanation:
You can find this out use the Rule of 72. By dividing 72 by the fixed interest rate, you can estimate the amount of time it will take for an investment to double in size:
= 72/10
= 7.2 years
= 8 complete years
Example:
Assume they invested $1,000. Interest rate is 10%.
Amount after 8 years will be:
= 1,000 * (1 + 10%)⁸
=$2,143.59
Investment is now more than double.

Rebecca bought candy boxes in the shape of a square pyramid to use for party favors. The side length of each box is 3.6 inches, and the height is 4 inches. Rebecca wants to fill each box with 20 pieces of candy. If each piece of candy is 0.8 in.³, will Rebecca be able to fit 20 pieces of candy into each candy box?
Answers
Answer:
Yes maybe.
Step-by-step explanation:
Well basically if we find the volume of 20 pieces of candy in all, that would be= 20*0.8= 16 cu.inches
And then if we find the volume of the square based pyramid, that would certainly be= 3.6*3.6*4 that is 51.84
Then lastly, if we do, 51.84 ÷16 the final answer will be 3.24. Which might actually be the answer as the pieces of candy certainly can't pass the limit 20 according to me.

A 51°
B 68°
C 90°
D 39°
Answers
Answer:
68 degrees
Step-by-step explanation:
To get the interior angle, we use an important triangle principle
The principle is that the sum of the opposite interior angles equal the exterior angle
Let the second interior angle be x
x + 51 = 119
x = 119-51
x = 68
