To find out how much money you have left after riding each ride once, subtract the total cost of all the rides from the amount of money you have. To find out if you have enough money to ride each ride twice, multiply the cost of each ride by 2 and check if it is less than or equal to the amount of money you have.
Explanation:a. To determine how much money you have left if you ride each ride once, you need to know the cost of each ride. Let's say each ride costs $3. To find out how much money you have left, you subtract the total cost of all the rides ($3 x number of rides) from the amount of money you have. So, in this case, you have $15 - ($3 x number of rides) left.
b. To determine if you have enough money to ride each ride twice, you multiply the cost of each ride by 2 and check if it is less than or equal to the amount of money you have. So, if each ride costs $3, you would calculate $3 x 2 = $6 to see if it is less than or equal to $15.
A building casts a shadow that is 420 meters long. At the same time, a person who is 2 meters tall casts a shadow that is 24 meters long. How tall is the building?
Answer:
35 Meters
Step-by-step explanation:
Ratio is 12
What I mean by that is 2 turns into 24 because you multiply 12 to it. Same thing for 420, except for the fact that you divide it (working backwards). So 420 divided by 12 equals 35:) Enjoy your day
Answer:

A triangle has an area of 24 meters squared and base length of 8m. Find the height.
Answer:
h = 6
Step-by-step explanation:
Since 1/2 times the base length times the height equals the area, just work your way backwards to get the answer!
It looks like this
(1/2)8 * h = 24
First multiply 1/2 by 8 to get 4
then divide 4 out of both sides so that h = 6!

Step-by-step explanation:
Given
3ab - 6b² - 2bc + ac ← Rearranging
= 3ab + ac - 6b² - 2bc (factor the first/second and third/fourth terms )
= a(3b + c) - 2b(3b + c) ← factor out (3b + c) from each term
= (3b + c)(a - 2b)
Answer:
(a-2b)(3b-c)
Step-by-step explanation:
3ab-6b^2-2bc+ac
Let's rearrange
3ab+ac-6b^2-2bc
Let's factorise
a(3b+c)-2b(3b+c)
(a-2b)(3b+c)
Since the answer cannot be solved further
The answer is (a-2b)(3b+c)

Bottles of mango juice are assumed to contain 275 milliliters of juice. There is some variation from bottle to bottle because the filling machine is not perfectly precise. Usually, the distribution of the contents is approximately Normal. An inspector measures the contents of seven randomly selected bottles from one day of production. The results are 275.4, 276.8, 273.9, 275.0, 275.8, 275.9, and 276.1 milliliters. Do these data provide convincing evidence at α = 0.05 that the mean amount of juice in all the bottles filled that day differs from the target value of 275 milliliters? (4 points)
Group of answer choices
Because the p-value of 0.0804 is greater than the significance level of 0.05, we fail to reject the null hypothesis. We conclude the data provide convincing evidence that the mean amount of juice in all the bottles filled that day does not differ from the target value of 275 milliliters.
Because the p-value of 0.0804 is greater than the significance level of 0.05, we reject the null hypothesis. We conclude the data provide convincing evidence that the mean amount of juice in all the bottles filled that day differs from the target value of 275 milliliters.
Because the p-value of 0.1609 is greater than the significance level of 0.05, we fail to reject the null hypothesis. We conclude the data provide convincing evidence that the mean amount of juice in all the bottles filled that day does not differ from the target value of 275 milliliters.
Because the p-value of 0.1609 is greater than the significance level of 0.05, we reject the null hypothesis. We conclude the data provide convincing evidence that the mean amount of juice in all the bottles filled that day differs from the target value of 275 milliliters.
Because the p-value of 1.5988 is greater than the significance level of 0.05, we fail to reject the null hypothesis. We conclude the data provide convincing evidence that the mean amount of juice in all the bottles filled that day does not differ from the target value of 275 milliliters.
Answer:
The correct option is;
c. Because the p-value of 0.1609 is greater than the significance level of 0.05, we fail to reject the null hypothesis. We conclude the data provide convincing evidence that the mean amount of juice in all the bottles filled that day does not differ from the target value of 275 milliliters.
Step-by-step explanation:
Here we have the values
μ = 275 mL
275.4
276.8
273.9
275
275.8
275.9
276.1
Sum = 1928.9
Mean (Average), = 275.5571429
Standard deviation, s = 0.921696159
We put the null hypothesis as H₀: μ₁ = μ₂
Therefore, the alternative becomes Hₐ: μ₁ ≠ μ₂
The t-test formula is as follows;
[tex]t=\frac{\bar{x}-\mu }{\frac{s}{\sqrt{n}}}[/tex]
Plugging in the values, we have,
Test statistic = 1.599292
[tex]t_{\alpha /2}[/tex] at 7 - 1 degrees of freedom and α = 0.05 = ±2.446912
Our p-value from the the test statistic = 0.1608723≈ 0.1609
Therefore since the p-value = 0.1609 > α = 0.05, we fail to reject our null hypothesis, hence the evidence suggests that the mean does not differ from 275 mL.
Answer:
Because the p-value of 0.1609 is greater than the significance level of 0.05, we fail to reject the null hypothesis. We conclude the data provide convincing evidence that the mean amount of juice in all the bottles filled that day does not differ from the target value of 275 milliliters.

By what percent will the fraction change if its numerator is
increased by 25% and its denominator is increased by 20%?
Answer:
The fraction increase by ( [tex]0.047=4.7\:\%[/tex] ) if its numerator is
increased by 25% and its denominator is increased by 20%.
Step-by-step explanation:
Let 'n' be the numeratorLet 'd' be the denominatorAs
[tex]100\%\mathrm{\:in\:fractions}=\:1[/tex]
[tex]25\%\mathrm{\:in\:fractions}=\:\frac{1}{4}[/tex]
[tex]20\%\mathrm{\:in\:fractions}=\frac{1}{5}[/tex]
so
Increase in 25% means
[tex]100\%\:+25\%\:=\frac{5}{4}[/tex]
Increase in 20% means
[tex]100\%\:+20\%\:=\frac{6}{5}[/tex]
Thus the fraction becomes
[tex]\:\frac{\frac{5}{4}\times \:n}{\frac{6}{5}\times \:d}[/tex]
[tex]=\frac{\frac{5}{4}n}{\frac{6d}{5}}[/tex]
[tex]\mathrm{Divide\:fractions}:\quad \frac{\frac{a}{b}}{\frac{c}{d}}=\frac{a\times \:d}{b\times \:c}[/tex]
[tex]=\frac{5n\times \:5}{4\times \:6d}[/tex]
[tex]=\frac{25n}{24d}[/tex]
[tex]=1.0417\left(\frac{n}{d}\right)[/tex]
[tex]=1\left(\frac{n}{d}\right)+0.047\left(\frac{n}{d}\right)[/tex]
As
[tex]0.047=4.7\:\%[/tex]
Therefore, the fraction increase by ( [tex]0.047=4.7\:\%[/tex] ) if its numerator is
increased by 25% and its denominator is increased by 20%.
A waiter at a restaurant receives a 15% tip on a $25 bill. At the same restaurant, a waitress receives a 20% tip on a $20 bill.
Who gets the larger tip? By how much?
Answer:
The waitress who received 20% of $20 gets a larger tip.
The waitress who received 20% of $20 gets $4.00 tip, and the waitress who received 15% of $25 gets a tip of $3.75
Step-by-step explanation:
To get 15% of 25, you multiply it by .15, giving you your answer.
To get 20% of 20, you multiple it by .20, giving you your answer.
Answer:
the second waiter gets a larger tip by $0.25
Step-by-step explanation:
15% of $25 is $3.75
the first waiter only got a $3.75 tip.
20% of $20 is $4
the second waiter got a $4 tip
the second waiter got $0.25 more than the first.

Wayne has 16 3/4 gallons in his car. If he used 2/5 of the gas in his car, how many gallons does he have left
Answer:
Wayne has 10.05 gallons left.
Step-by-step explanation:
16 3/4 times 2/5 is 6.7
16 3/4 minus 6.7 is 10.05
Wayne has 327/20 gallons of fuel left in his car.
What is a fraction?Fractions represent the parts of a whole or collection of objects. A fraction has two parts. The number on the top of the line is called the numerator.The number on the bottom of the line is called the denominator.
Now it is given that,
Amount of fuel in the car = 16 3/4 gallons = 67/4 gallons
Amount of fuel used = 2/5 gallons
Therefore,
Amount of fuel left in the car = Amount of fuel in the car - Amount of fuel used
⇒ Amount of fuel left in the car = 67/4 - 2/5
⇒ Amount of fuel left in the car = 327/20 gallons
Thus, Wayne has 327/20 gallons of fuel left in his car.

Joanna has been saving for retirement for 40 years. She made monthly deposits of $275 and earned 5.6% annual interest, compounded monthly. According to her account documents, after these 40 years, she has a balance of $491,730.35 in her account. How much of this did Joanna contribute and how much of this is interest?
Joanna deposited $132000 and her interest amount is $359730.35
Step-by-step explanation:
Monthly deposit = $275
Interest = 5.6%
Time = 40 years
After 40 years her account balance = $491730.35
If she deposit $275 monthly then after 40 years she will have deposited ,
= 275 x 12 x 40
= $132000
The remaining is her interest amount.
Interest amount = 491730.35 - 132000
= $359730.35
Joanna deposited $132000 and her interest amount is $359730.35
