Answer:
Jiri is 24 years old.
Step-by-step explanation:
Let "J" represent Jiri's age.
We could use "P" to represent Pamela's age, but that wouldn't help us in solving this problem.
However, we do know that Pamela's age is 3 times Jiri's age, so we can write Pamela's age to be 3J (3 times Jiri's age.)
We also know that the sum of their ages is 96.
Thus, we have: Jiri's Age + Pamela's Age = 96 years of age.
And: J + 3J = 96
Simplifying, we obtain: 4J = 96
Divide by 4 on both sides: J = 24

How much water do you add to make 12% sugar syrup using 5g sugar.
Answer:
You know that 5 g of sugar form 12%. Let x g be the amount of water needed. The total amount of syrup will be x+5 g. Then
5 g - 12%,
x+5 g - 100%.
mathematically you can write a proportion;
5/x+5=12/100
=>500=12(x+5)
,500=12x+60
,12x=400,
x=440/12
=110/3
=36 2/3g of water36.66 grams of water is added to make 12% sugar syrup using 5g sugar.
What is Ratio?A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.
Let the amount of water is added be 'x'.
Amount of sugar = 5 g
We need to make 12% of sugar syrup.
x grams of water is added to 5 g of sugar, to 12% of sugar syrup.
5/5+x=12/100
Apply cross multiplication
5×100=12(5+x)
500=60+12x
Subtract 60 from both sides
440=12x
Divide both sides by 12
x=36.66
Hence, 36.66 grams of water is added to make 12% sugar syrup using 5g sugar.

Step-by-step explanation:
The Ice Chalet offers dozens of different beginning ice-skating classes. All of the class names are put into a bucket. The 5 P.M., Monday night, ages 8 to 12, beginning ice-skating class was picked. In that class were 64 girls and 16 boys. Suppose that we are interested in the true proportion of girls, ages 8 to 12, in all beginning ice-skating classes at the Ice Chalet. Assume that the children in the selected class are a random sample of the population. Construct a 92% Confidence Interval for the true proportion of girls in the ages 8 to 12 beginning ice-skating classes at the Ice Chalet.
Answer:
The 92% Confidence Interval for the true proportion of girls in the ages 8 to 12 beginning ice-skating classes at the Ice Chalet is (0.722, 0.878).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].
For this problem, we have that:
64 + 16 = 80 children, of which 80 are girls. So
[tex]n = 80, p = \frac{64}{80} = 0.8[/tex]
92% confidence level
So [tex]\alpha = 0.08[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.08}{2} = 0.96[/tex], so [tex]Z = 1.75[/tex].
The lower limit of this interval is:
[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.8 - 1.75\sqrt{\frac{0.8*0.2}{80}} = 0.722[/tex]
The upper limit of this interval is:
[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.8 + 1.75\sqrt{\frac{0.8*0.2}{80}} = 0.878[/tex]
The 92% Confidence Interval for the true proportion of girls in the ages 8 to 12 beginning ice-skating classes at the Ice Chalet is (0.722, 0.878).

Diameter= 4.77 feet
Step-by-step explanation:
The circumference of a circle, C = 15 feet
We need to find the diameter of the circle.
We know that,
Circumference = 2πr
2r is the diameter of the circle.
So,
C = πd
[tex]d=\dfrac{C}{\pi}\\\\d=\dfrac{15}{\pi}\\\\d=4.77\ \text{feet}[/tex]
So, the diameter of the circle is 4.77 feet.

x varies directly with y. if y = -57 when x = 9, find x when y = 27.
Answer:
x = -81 / 19
Step-by-step explanation:
y = kx

k = -57/9 or -19/3
27 = [tex]\frac{-19x}{3}[/tex]
-19x = 81
x = -81 / 19

What is the best scenario for the most profit in purchasing office equipment?
O pay $30,000 cash for $45,000 in revenue
O pay an installment loan of $25,000 with APR of 15% for 18 months and $40,000
O pay an installment loan of $28,000 with APR of 12% for 30 months and $45,000 in revenue
o
pay an installment loan of $32,000 with APR of 20% for 12 months and $50,000 in revenue
Answer:
A, the first answer, the cash option
Step-by-step explanation:
APR = annual percentagte rate. Knowing this, we know that the full percent of interest is taken every 12 months. So, knowing this, we can figure this question out pretty easy by subtracting the revenue of each answer by the full payment of the loan and finding out which is the highest.
The first gives 15k profits (45-30)
The second has a loan of 25,000 over 18 months, which is 1.5x 15 = %22.5 interest you have to pay on this loan, which is 5625 dollars (.225 * 25000), added to the loan of 25,000 is 30,625 and a rev of 40k, which profits ~10k so not the right ans
The third has 2.5 x the interest rate of 12 so 30% of your loan of 28,000 which brings you to 8400 in interest and 36400 total, subtracting from 45000 is ~9k profit
The fourth is 20% of 32,000 which is 6,400, added is 38,400 subtracted from 50k rev is 11k in profit
Looking at these, we can conclude the highest profit is the cash option.
Also, a little tip, APR only holds interest on the principal loan, while APY is compound interest

melissa purchased a car at the price of 20,540 with a down payment of 3,900 and financed the rest paying 8.6% interest compounded monthly over a payment period of 5 years she also had to pay 8.25% sales tax a $955 registration fee and $57 documentation fee what is her monthly payment
Answer:
$478.06
Step-by-step explanation:
let's first start out by figuring out the present value of the loan
((20540*1.0825)+955+57)-3900
Which gives me a value of 23246.55
I'm then going to assume that the 8.6% is a nominal interest rate meaning that the effectively monthly rate is equal to .086/12=.0072
Which means we have
23246.55=X(a angle 60 at .0072) (i'm using annuities to solve this if you don't know what this is just ask)
Solve this and get $478.06

The odds in favor of an event are 2:9. What are the odds against the event?
Answer:
The odds against the event are 9:11.
Step-by-step explanation:
The odds being in favor and against an event are complemmentary, that is, their sum is 100% = 1.
The odds in favor of an event are 2:9.
So for each 2 times the event will happen, it wont happen 9 times, in a total of 2 + 9 = 11
So the odds against the event are 9:11.
d varies jointly as h and g. if d=15 when h= 14 and g=5, find g when h=21 and d=8
Answer:
g = 1.78
Step-by-step explanation:
Given that,
d varies jointly as h and g.
[tex]d=khg[/tex] .....(1)
Where
k is constant of proportionality.
Put d=15, h= 14 and g=5 in equation (1) to find k.
[tex]k=\dfrac{d}{hg}\\\\k=\dfrac{15}{14\times 5}\\\\k=\dfrac{3}{14}[/tex]
Now, put k = 3/14, h = 21 and d = 8 in equation (1) to find g.
[tex]g=\dfrac{d}{kh}\\\\g=\dfrac{8}{\dfrac{3}{14}\times 21}\\\\g=1.78[/tex]
So, the required value of g is 1.78.

The ratio of berries to oranges is 10:1 if there are 25 oranges how many berries are there
Answer:
250 berries
Step-by-step explanation:
We know that the ratio of berries to oranges is 10:1. This ratio tells us, for every one orange, there should be ten berries. But, now we have 25 oranges:
For every orange there are ten berries, and since we have 25 oranges, we can write an expression:
25 oranges * 10 = 250 berries
There are 250 berries.
