Aaron is 6 years old, Beth is 9 years old and Charlie is 15 years old. They are going to share £5940 in the same ratio as their ages. How much do they each receive?
Answer:
[tex]Aaron=1188[/tex]
[tex]Beth=1782[/tex]
[tex]Charlie=2970[/tex]
Step-by-step explanation:
From the question we are told that
Ratio 6:9:15
Total amount to e shared N=£5940
Generally the Ratio can divide the Total amount mathematically as follows
Ratio
6:9:15/3=2:3:5
Sum of ratio
2+3+5=10
For Aaron
[tex]A=\frac{2}{10} *5940[/tex]
[tex]A=1188[/tex]
For Beth
[tex]B=\frac{3}{10} *5940[/tex]
[tex]B=1782[/tex]
For Charlie
[tex]C=\frac{2}{10} *5940[/tex]
[tex]C=2970[/tex]
Check answer
[tex]A+B+C=5940\\1188+1782+2970=5940[/tex]
In one day the National Civil Rights Museum in Memphis Tennessee admitted 321 people and collected $1590. The price of admission is $6 for adults and $4 for children under 13. How many adults and how many children were admitted to the museum that day?
Answer:
Step-by-step explanation:
a + c = 321
6a + 4c = 1590
c = 321 - a
6a + 1284 - 4a = 1590
2a = 306
a = 153
c = 168

Megan Dunstall wants to know how many months it would take for $15,000 to earn $618.75 at 51/2% of simple interest?
Answer: 9 months.
Step-by-step explanation:
Simple interest = Principal x rate(in decimal) x Time(in years)
Given: Principal = $15,000 , rate = [tex]5\dfrac12\%=\dfrac{11}{2}\%= 5.5\%= 0.055[/tex]
Interest = $618.75
let t= time
Then,
[tex]618.75=15000\times 0.055\times t\\\\\Rightarrow\ t=\dfrac{618.75}{15000\times0.055}\\\\\Rightarrow\ t= 0.75\ or\ t=\dfrac34\ year[/tex]
1 year =12 months
[tex]\dfrac34\ year=\dfrac34\times12 = 9\ months[/tex]
Hence, it will take 9 months.

Cindy spent $65.25 on ingredients for blueberry pies and $62.84 on ingredients for cherry pies. Each slice of ple sells for $3.50.
Part A
Write an expression to represent Cindy's profit if she sells b slices of blueberry pie and C slices of cherry ple.
Part B
Cindy sells 24 slices of blueberry ple and 15 slices of cherry ple. The ne
xt day, she sold 26 slices of blueberry ple and 17 slices of cherry pie. What was her total profit?
The expression that represents Cindy's profit is $3.5b - $128.09.
Cindy's total profit is $30.82.
What is profit?Profit is total revenue less total cost. Total revenue is the selling price per unit multiplied by the total units sold.
Profit = total revenue - total cost
($3.50b) - ($65.25 + $62.84)
$3.5b - $128.09
What is Cindy's total profit?Profit for the first day = $3.5(24 + 15) - $128.09
= ($3.5 x 39) - $128.09
= $136.50 - $128.09
=$8.41
Profit for the next day = $3.5(26 + 17) - $128.09
= ($3.5 x 43) - $128.09
= $150.50 - $128.09
= $22.41
Total profit = $22.41 + $8.41 = $30.82

What is the equation of the line that passes through the point (5, -2) and has a slope of 6/5
Answer: y = (6/5)x-8
Slope = 6/5 = 1.2
Y intercept = -8
==================================================
Work Shown:
m = 6/5 = 1.2 is the given slope
(x,y) = (5,-2) is the point the line goes through
y = mx+b .... slope intercept form
y = 1.2x + b .... plug in the given slope
-2 = 1.2*5 + b ... plug in the coordinates of the given point
-2 = 6 + b
-2-6 = 6+b-6 .... subtracting 6 from both sides
-8 = b
b = -8
The equation y = mx+b turns into y = 1.2x-8
This is equivalent to y = (6/5)x-8
Ocsar and his little brother made up a game using coins. They flip the coin towards a cup and receive points for every one that makes it in. Oscar starts with 20 points, and his little brother starts with 18 points. Oscar gets 2 points for every successful shot, and his brother, since he is younger, gets 3 points for each successful shot. Eventually, the brother will have a tied score in the game. How many additional shots will each brother have made? How many points will they both have?
they both would have 24
they both would have 2 successful shots. they would mean that the older brother added 4 point to his score and the younger brother would have added 6 to his score

Jill is studying a strange bacterium. When she first looks at the bacteria, there are initially.
100 cells in her sample. The next day, there are 300 cells (Day 1). Intrigued, she comes
back the next day to find that there are 900 cells (Day 2)!
bo.
How many bateria cells will there be when Jill looks at her sample on Day 4?
Answer:
8100
Step-by-step explanation:
We first see that in the first day it tripled from 100 to 300 this is the pattern that is seen throughout this whole experemint, we can see that the cells triple again on the second day to get 900 cells from this. It is likely to say that they will triple again on the third day to get 2100 and again on the fourth to get 8100

I need help graphing -8x-y=8
Answer:
y = -8x - 8
Step-by-step explanation:
Add -8x on both sides to get -y = 8x + 8 and flip the y sign on the left to get your slope function which is y = - 8x - 8.
To graph the function, you would need to put (0, -8) as your y-intercept, and each unit will go down 8 units when you add 1.
Answer:
y=8x+8
Step-by-step explanation:
Just rewrite the problem so it's in y=mx+b format then it's easy to graph
Remember the y intercept is 8 because when x=0 y=8 and the slope is 8 so go up 8 and right 1
Put the following lengths in ascending order, 900cm, 8.9m, 895cm, 9.1m, 12000mm, 0.0092km.
Answer: 8.9 m, 895 cm, 900 cm, 9.1 m, 0.0092 km, 12000 mm
===========================================================
Explanation:
To be able to compare these various measurements, all of them must be the same unit. Let's convert each measurement to meters. If the measurement is already in meters, then we'll move onto the next measurement.
Here are some useful conversion factors
1 m = 100 cm1 m = 1000 mm1 km = 1000 mWith those conversion factors in mind, we get the following conversions:
900 cm = (900 cm)*(1 m/100 cm) = (900/100) m = 9 m8.9 m = already in meters, moving on895 cm = 8.95 meters; divide by 100 to convert from cm to meters as shown above9.1 m = already in meters, moving on12000 mm = (12000 mm)*(1 m/1000 mm) = (12000/1000) m = 12 m0.0092 km = (0.0092 km)*(1000 m/1 km) = (0.0092*1000) m = 9.2 mHere is the summary of the conversions:
900 cm = 9 m8.9 m = 8.9 m895 cm = 8.95 m9.1 m = 9.1 m12000 mm = 12 m0.0092 km = 9.2 mThe original list of
{900cm, 8.9m, 895cm, 9.1m, 12000mm, 0.0092km}
becomes this equivalent list
{9 m, 8.9 m, 8.95 m, 9.1 m, 12 m, 9.2 m}
in that exact order.
After converting everything to meters, we can then sort the values from smallest to largest. Doing so gets us this sorted list of
{8.9 m, 8.95 m, 9 m, 9.1 m, 9.2 m, 12 m}
Then you convert back each measurement to its original form
{8.9 m, 895 cm, 900 cm, 9.1 m, 0.0092 km, 12000 mm}
which is the final answer.
-7 + (-9) - (-11) -2
I don't know how to solve for any of the values so please help me!!
