Tyler wants to ride the bumper cars 4 times and Ferris wheel 8 times. It costs 6 tickets to ride the bumper cars and 3 tickets to ride the Ferris wheel. How many tickets does tyler need? Show work.

To find the cost of 4 5/7 kg of candy, we divide the cost of 5/6 kg by 5/6 to find the cost of 1 kg. Then, we multiply the cost of 1 kg by 4 5/7 to find the total cost.

To find the cost of 4 5/7 kg of candy, we need to find the cost of 1 kg of candy and then multiply it by 4 5/7. Given that 5/6 kg of candy costs $7.50, we can find the cost of 1 kg by dividing $7.50 by 5/6. So, the cost of 1 kg of candy is $9.00. To find the cost of 4 5/7 kg, we multiply $9.00 by 4 5/7.

To multiply a whole number and a fraction, we first convert the whole number to a fraction by placing it over 1. So, 4 can be written as 4/1. Then, we multiply the numerators (4 x 7 + 5) and the denominators (1 x 7). This gives us 33/7. Finally, we multiply $9.00 by 33/7 to find the cost of 4 5/7 kg of candy.

The cost of 4 5/7 kg of candy is $38.57.

There are hours 2 will it take to fill the pool if it holds 80,000 gallons.

Any relationship that is always in the same ratio and quantity which vary directly with each other is called the proportional.

Given that;

Two hoses are used to fill a swimming pool.

And, Together they fill the pool at a rate of 3 gallons every 5 seconds.

Hence, Time for to fill 80,000 gallons are,

⇒ Time = 80,000 × 3 / 5

⇒ Time = 16,000 × 3

⇒ Time = 48,000 seconds

⇒ Time = 48,000 / 36,000 hours

⇒ Time = 1.33 hours

Final answer:

Casey spent $12 on chips that cost $2 per bag, so she bought 6 bags of chips.

Explanation:

Casey bought 5 sandwiches at $6 each, totaling $30 spent on sandwiches. Since she spent $42 in total, we subtract the amount spent on sandwiches from the total amount to find out how much she spent on bags of chips: $42 - $30 = $12 spent on chips. Each sandwich cost three times as much as a bag of chips, so one bag of chips costs $6 / 3 = $2. To find out the number of bags of chips b she bought, we divide the total spent on chips by the cost of one bag: $12 / $2 = 6 bags of chips.

Answer:

she use altogether flour is [tex]1 \frac{3}{20}[/tex] lb

Step-by-step explanation:

given data

flour to bake a vanilla cake = [tex]\frac{2}{5}[/tex] lb

flour to bake a chocolate cake =  [tex]\frac{3}{4}[/tex] lb

to find out

How much flour did she use altogether

solution

we know here flour use to make cake

so total flour is used = add both flour for vanilla and chocolate cake

total flour is used =  [tex]\frac{2}{5}[/tex] +  [tex]\frac{3}{4}[/tex]

total flour is used =  [tex]\frac{23}{20}[/tex]

she use altogether flour is [tex]1 \frac{3}{20}[/tex] lb

Answer: [tex]\frac{23}{20}\ lb[/tex] or [tex]1\frac{3}{20}\ lb[/tex]

Step-by-step explanation:

For this exercise you need to add fractions.

To bake the vanilla cake, Penny used [tex]\frac{2}{5}\ lb[/tex] of flour and to bake the chocolate cake she used [tex]\frac{3}{4}\ lb[/tex] of flour.

Then, the total flour she used can be found by solving this addition:

[tex]\frac{2}{5}\ lb+\frac{3}{4}\ lb[/tex]

Since the denominators are different, you must find the Least Common Denominator (LCD).

Descompose the denominators into their prime factors and multipy the commons and non-commons with the highest exponent.

Then:

[tex]5=5\\\\4=2*2=2^2[/tex]

[tex]LCD=5*2^2=20[/tex]

So, the sum is:

[tex]\frac{2}{5}+\frac{3}{4}=\frac{4(2)+5(3)}{20}=\frac{23}{20}[/tex]

That improper fraction can be written as a mixed number.

When you divide the numerator 23 by the denominator 20 you get;

Then:

[tex]\frac{23}{20}\ lb=1\frac{3}{20}\ lb[/tex]

C. 8 times

Step-by-step explanation:

The county-fair prize wheel has equally spaced sections with the following colors: 1 is golden, 2 are silver, 3 are green, 4 are blue, 6 are red, and 9 are yellow, 25 sections in total.

A. The probability of landing on gold is

[tex]P_1=\dfrac{\text{Number of favorable outcomes}}{\text{Number of all possible outcomes}}=\dfrac{1}{25}=0.04[/tex]

or 4% as a percent.

B.  If the probability of landing on yellow is 36% (or 0.36 as decimal), then the probability of not landing on yellow is

[tex]P_2=1-0.36=0.64[/tex]

or 64% as a percent.

C. If the wheel is spun 1 time, the probabilty of landing on silver is

[tex]P_3=\dfrac{2}{25}=0.08[/tex]

or 8% as a percent.

If the wheel is spun 100 times, the expected number of landing on silver is

[tex]100\cdot 0.08=8[/tex]

Final answer:

Explaining the probability of landing on different colors on a prize wheel and the expected outcomes in 100 spins.

Explanation:

a) What is the probability of landing on gold?

There is 1 golden section out of a total of 25 sections on the prize wheel.

Probability of landing on gold: 1/25 or 4%

b) If the probability of landing on yellow is 36%, what is the probability of not landing on yellow?

If the probability of landing on yellow is 36%, then the probability of not landing on yellow is 64%.

c) If the wheel is spun 100 times, how many times would you expect to land on silver?

Since there are 2 silver sections on the wheel, the probability of landing on silver is 2/25. Therefore, expected number of times to land on silver in 100 spins is 100 x 2/25 = 8 times.

The common denominator you can calculate as the least common multiple of the both denominators - LCM(8, 2) = 8. The fraction result cannot be further simplified by cancelling.

In words - three eighths plus one half = seven eighths.

Answer:7/8

Step-by-step explanation:The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.

LCD(3/8, 1/2) = 8

Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.

(3/8×1/1)+(1/2×4/4)=?

Complete the multiplication and the equation becomes

3/8+4/8=?

The two fractions now have like denominators so you can add the numerators.

Then:

3/8+4/8=7/8

This fraction cannot be reduced.

Answer:2y(3) +6 +5x(3)

(The numbers in parentheses mean they’re an exponent)

Step-by-step explanation:

Adding like terms means to simply combine terms with the same variable and/or exponent

Since there are three numbers with the same variable (y) they are combined. Since there are three numbers without an exponent/ variable,(the 3 twos) they are combined. There is no other term that can be combined with 5x(3), so you just leave it as is.

Final answer:

A discount represents the decrease in the item's price during a sale, leading to consumer savings. When a shopper gets a "good deal," they experience the substitution and income effect, which typically results in an increased quantity demanded of the product.

Explanation:

When buying an object on sale, the discount is the decrease in the price of the item. Economists may refer to the situation of getting a "good deal" on a product when the consumer is able to purchase something at a price lower than what it normally sells for, leading to consumer saving. This occurs due to the substitution effect and the income effect. The substitution effect indicates that when a product is cheaper relative to other products, consumers are likely to purchase more of it. On the other hand, the income effect explains that the decrease in price allows the consumer to buy the same amount of goods while still having extra money to purchase even more goods. Due to both these effects, a decrease in price typically leads to an increase in quantity demanded, which might suggest that the demand for a product is elastic if the quantity demand decreases significantly more than the price increase.

Final answer:

A valid prediction about a continuous function is that it will have no breaks, jumps, or holes, and will exhibit the intermediate value property. If continuity is ensured, we can expect the function to pass through all intermediate values between any two points within a given interval.

Explanation:

A valid prediction about a continuous function is that the function will not have any breaks, jumps, or holes in its graph. This means that for any value within the domain of the function, we can find a corresponding value in the range, making the function predictable and reliable to analyze. A continuous function has the intermediate value property, which tells us that if the function takes on two values, it must take on every value in between at least once. As such, if we know the function is continuous on an interval, we can predict that it will pass through all the intermediate values between any two points in that interval.

An important concept to consider is the change that would invalidate the continuity of such a function. To illustrate, think about what would happen if our continuous function were to suddenly have a point removed or to have a sudden vertical asymptote introduced. This would create a discontinuity. So, when predicting behaviors of continuous functions, we must ensure there are no such changes or 'breaks' occurring within the interval we are considering.

Answer:

B.0 < x ≤ 12 and 0 < y ≤ 36

Step-by-step explanation:

Final answer:

The constraints for a thriving population of gazelles at the zoo, with a limit of 12 female gazelles and the need for thrice as many males, are 0 < x ≤ 12 and 0 < y ≤ 36, which matches answer option B.

Explanation:

To represent a thriving population of gazelles in the zoo, we must write constraints that capture the relationship between the number of female gazelles (x) and the number of male gazelles (y). Since the zoo can only accommodate 12 female gazelles, and the herd requires three times more males than females, we can express the constraints as inequalities.

The first constraint pertains to the maximum number of female gazelles, which is 12. Therefore, we have 0 < x ≤ 12. The second constraint relates to the male gazelles, as we need three times as many males as there are females, so y = 3x. Since x has an upper limit of 12, the maximum value for y would be 36 (3 times 12).

Taking into account that we cannot have a negative number of gazelles, the constraints for a population to thrive are:

Given these constraints, the correct answer is B. 0 < x ≤ 12 and 0 < y ≤ 36.

x = liters of 20% solution

Mixing the 20% solution with the 60 L of 90% solution gives a new mixture with volume (x + 60) L. Each L of the 20% solution contributes 0.2 L of alcohol and thus a total of 0.2x L of alcohol, while the 60 L of 90% solution contributes 54 L of alcohol.

We want the concentration of the new mixture to be 80%, so we require

[tex]\dfrac{0.2x+54}{x+60}=0.8[/tex]

Solve for x:

[tex]0.2x+54=0.8x+42[/tex]

[tex]12=0.4x[/tex]

[tex]\implies\boxed{x=30}[/tex]

So you will need 30 L of the 20% solution.

To get a 80% solution, you would need to mix a certain number of liters of a 20% alcohol solution with 60 liters of a 90% solution.

To solve this problem, we can use the concept of mixture problems. Let's denote the unknown quantity of the 20% alcohol solution as 'x'. We know that the total volume of the mixture will be the sum of the volumes of the two solutions, so:

x + 60 = x + 60

Next, we can express the amount of alcohol in the original 90% solution and the resulting 80% solution:

0.90(60) + 0.20(x) = 0.80(x + 60)

Simplifying this equation will give us the value of 'x', which represents the number of liters of the 20% alcohol solution that must be added to the 60 liters of the 90% solution.
