There are 144 people in an audience. The ratio of adults to children is 5 to 3. How many children are in the audience.
Answer:
In the audience, there are 90 adults and 54 children
Step-by-step explanation:
If we have 5 adults for every 3 children, we would continue this pattern by saying we have 10 adults for every 6 children, 15 adults for every 9 children, and so on.
We can express this situation into an equation by saying 5x + 3x = 144
8x = 144
x = 18
So now we know there are 5(18) = 90 adults for every 3(18) = 54 children
In the audience, there are 90 adults and 54 children
Answer:
In the audience, there are 90 adults and 54 children

6. Carla runs 3 miles in 30 minutes.
Find the number of miles Carla runs each minute. Show your work using mathematics.
Find the number of minutes Carla runs for each mile. Show your work using mathematics.
Answer:
Carla ran 0.1 miles per minute.
Step-by-step explanation:
To solve this, we need to use the distance formula.
The formula is d=rt, where d is the distance traveled, r is the rate in which the distance is traveled, and t is the amount of time it took to go that distance. So lets plug it all in.
d=rt
3=(r)(30)
Now, we need to do the inverse of multiplying 30 to both sides, which would be the same as dividing by 30 on both sides.
3/30=(r)(30/30)
0.1=r
The rate is 0.1. Carla ran 0.1 miles per minute.

#LearnWithEXO
Answer:
2hrs 30 mins on Friday or 2:30 in the afternoon on Friday
Step-by-step explanation:
it took the aero plane 8 h 45 minutes to travel
it reached its destination at 6 : 15 on Friday
to find the time and day it started, we just subtract the time it used to travel from the time and day it landed
which is;
8 45
-6 15
=2 30
that is 2hrs 30mins on Friday

Answer:
JK = 42 , KL = 78
Step-by-step explanation:
JK + KL = JL , substitute values
4x + 6 + 7x + 15 = 129 , that is
11x + 21 = 120 ( subtract 21 from both sides )
11x = 99 ( divide both sides by 11 )
x = 9
Then
JK = 4x + 6 = 4(9) + 6 = 36 + 6 = 42
KL = 7x + 15 = 7(9) + 15 = 63 + 15 = 78

Hamish buys a new car for 520000
The car depreciates in value by 19% each year.
Work out the value of the car at the end of 3 years.
Give your answer to the nearest $.
Answer:
$223,600
Step-by-step explanation:
1. Multiply 520000 by 0.19 and get an answer of 98800. This is how much by which the car depreciates every year.
2. Now multiply 98800 by 3 (years). Now your answer would be 296400.
3. Now minus the depreciated value from the original value which is 520000-296400=223600.
Not sure about the answer but I hope this helped a bit
Answer:
$3,567.00
Step-by-step explanation:
Here is how I got it!
First, you will have to borrow the 520,000 from the word problem.
Next, multiply 520,000 with 0.19 with the power of 3
[tex]520,000*0.19^3=n[/tex]
The 3 is the number of years, n is the nearest $ answer.
--
First, do [tex]0.19^3[/tex]
[tex]0.19*0.19*0.19=0.006859[/tex]
(Again, that's a crazy number!)
--
With 0.006859, multiply it with 520,000
[tex]520,000*0.006859=3566.68[/tex]
3566.68 is technically (in money) $3,566.68 (with .68 being sixty-eight cents).
--
Finally, it states to answer to the nearest $.
Just round up the .68 to 1 dollar which will just add one more dollar to 3,566
[tex]3,566.32[/tex] ⇒ [tex]3,567.00[/tex] (since .32 is below .50, you can't round it UP)
Add you $ symbol
With the result being: $3,567.00

Round 6,248 to the nearest hundred
Answer:6200
Step-by-step explanation:
:We round the number up to the nearest hundred if the last two digits in the number are 50 or above.
: We round the number down to the nearest hundred if the last two digits in the number are 49 or below.
: If the last two digits are 00, then we do not have to do any rounding, because it is already to the hundred.
:In this case, Rule B applies and 6248 rounded to the nearest hundred is:
