Juice is made up by diluting concentrate with water in the ratio 1:5. If 200ml of concentrate is used ,how much juice will be made?
Answer: 1,200 ml
Step-by-step explanation:
The ratio is 1 : 5.
If 200 ml of concentrate is used, the water used will be:
1 : 5
200 : x
x = 1,000 ml of water
The amount of juice would be:
= water + concentrate
= 1,000 + 200
= 1,200 ml

Answer:
1. 4y-12
2. c
For #1 you distribute the 4 to the y and the 3. 4 times 3 equals 12.
For #2 you factor out the 3 and you get 3(5x+1)
Answer:
4y-12
Step-by-step explanation:
Multiply the outside number by the numbers in the bracket.
Example:4×y=4y Because y=1
4×3=12
2.Answer C
3(5x+1)
3×5x=15x
3×1=1
Which is equivalent to 3(5x+3)

Find the marginal distribution of gender in counts.
Complete question :
Mavis is interested in whether military dependency is related to gender in American Samoa. Here is data she collected about the population of American Samoa in 2010.
Millitary status _________ female ____ Male
In armed forces _________ 28 _______ 59
Millitary dependent ______ 928 ______ 781
Civilian _______________ 26393 ___27330
Answer:
Male = 0.4193
Female = 0.5087
Step-by-step explanation:
To obtain the marginal distribution of gender :
Total number of civilians (male + female)
(26393 + 27330) = 53,723
Male :
P(male) = number of male / total
P(male) = 26393 / 53,723 = 0.4912793
P(Female) = number of Female / total
P(Female) = 27330 / 53,723 = 0.5087206
Put the following equation of a line into slope-intercept form, simplifying all fractions.
Answer:
3x - y = -3
Step-by-step explanation:
divide everything by 4, the greatest common factor. That's all you need to do.
Answer: y=3x+3
Step-by-step explanation:
12x -4y= -12
subtract 12x from both sides
-4y= -12x-12
Divide everything by -4 to make y positive and alone
y=3x+3

Can someone help me with this ?
Answer:
50
Step-by-step explanation:
12x + 15 = 5x + 85 {Subtract 15 from both sides}
12x + 15 - 15 = 5x + 85 - 15
12x = 5x + 70 {Subtract 5x from both sides}
12x - 5x = 70
7x = 70 {Divide both sides by 7}
x = 70/7
x = 10
∠U = 5x = 5*10 = 50

A ball is thrown into the air with a speed of 32 feet per second. The function h=32t - 16t^2 models the height of the ball after t seconds. How many seconds does it take for the ball to reach its maximum height?
Answer:
t = 1 s
Step-by-step explanation:
The function models the height of the ball after t seconds is given by :
[tex]h=32t - 16t^2[/tex]
We need to find how many seconds does it take for the ball to reach its maximum height.
For maximum height put dh/dt = 0
[tex]\dfrac{dh}{dt}=\dfrac{d}{dt}(32t - 16t^2)\\=32-32t[/tex]
So,
32-32t = 0
t = 1
So, it will take 1 second to reach its maximum height.

in 2001 John makes an investment investment and $50,000 decreases in value of the rate of 2.5% per year write an exponential function to find the value of the investment in 2010
Answer:
$39811.77
Step-by-step explanation:
If we put y as the unit of year, the function will be 50000x0.975^y (100%-2.5% is 97.5%). And so from 2001 to 2010, nine years has passed, so the equation will be 50000x0.975^9 And if you calculate and round the answer to the nearest hundredth (cent), you will find $39811.77.
A small radio station can broadcast in a circular range with a radius of 20 miles. About how many square miles is the area covered by this range? Use 3.14 for π.
The requried range of the radio station is given as 1256 square miles.
What is an area circle?The area of the circle is given by the pie times square of the radius.
A = πr², where r is the radius of the circle.
Here,
A small radio station can broadcast in a circular range with a radius of 20 miles.
The range is given by the area of the circle with given radius,
Area of the circle = πr²
Area of the circle = 3.14 × 20²
area of the circle = 1256 square miles
Thus, the requried range of the radio station is given as 1256 square miles.

Two customers took out car loans from a bank.
Robert took out a 4-year loan for $30,000 and paid 4.9% annual simple interest.
Susan took out a 6-year loan for $30,000 and paid 4.5% annual simple interest.
What is the difference between the amounts of interest Robert and Susan paid for their car loans?
Enter your answer in the box.
$ { }
Answer:
Susan pays $2220 more interest than Robert
Step-by-step explanation:
Interest = principle times rate times the time
I = PRT
Robert: I = 30000(.049)(4) = $5880
Susan: I = 30000(.045)(6) = $8100
8100 - 5880 = $2220
A salesperson's commission rate is 5%. What is the commission from the sale of $36,000 worth of furnaces? Use pencil and paper. Suppose sales would double. What would be true about the commission? Explain without using any calculations.
Answer:
a. $1,800
b. Commission would double as well.
Step-by-step explanation:
Commission paid on $36,000 worth of furnaces with a rate of 5% is:
= Amount of sales * commission rate
= 36,000 * 5%
= $1,800
If the sales were to double, the commission would be based on double the amount so it would double as well.
= 36,000 * 2
= $72,000
Commission = 72,000 * 5%
= $3,600
Commission therefore doubled.
Answer:
1,800
