The minimum number of hours Hiroto can tutor to make at least $180 is 2 hours.

From the information, Hiroto tutors Japanese for $15 an hour and works at a dairy for $10 an hour. He wants to work 15 hours this week and we want to calculate the minimum number of hours Hiroto can tutor to make at least $180.

Hiroto wants to earn at least $180 this week. If he works 15 hours at the dairy, he will earn 15 * $10 = $150.

To earn at least $180, he needs to earn an additional $180 - $150 = $30.

At $15/hour for tutoring, Hiroto needs to work 30 / 15 = 2 hours tutoring.

Answer:

1.8828 quarts of blue paint

2.1172 quarts of red paint

(check the explanation for more round off variations)

Step-by-step explanation:

Convert both fractions to decimals

\(\frac{2}{3}\) = 0.667

\(\frac{3}{4}\) = 0.75

Then turn the decimals to percentages

66.7%

75%

Then rewrite it as a fraction to find the missing percentages

75% : 1.417 = x : 1

Solve for x

x = 52.93

Then do this again for 66.7%

66.7% : 1.417 = x : 1

Solve for x

x = 47.07

Then find the values of these percentages relating to 1

47.07% of 1 is 0.4707

52.93% of 1 is 0.5293

Now we have how much blue paint and red paint is in each quart of purple paint

Multiply them by 4 to get the total

0.4707 x 4 = 1.8828

0.5293 x 4 = 2.1172

Now we have:

1.8828 quarts of blue paint

2.1172 quarts of red paint

Now if you want it to be rounded off to the nearest tenths or hundredths

1.8828 = 1.9 (hundredths = 1.88)

2.1172 = 2.1 (hundredths = 2.12)

Answer: Y= -3

Step-by-step explanation:

4(y+1)=-8

First you need to distribute the 4:

4(y+1)=-8  

4y+4=-8

Next you need to subtract 4 from both sides:

4y+4 =-8

4y+4-4=-8-4

Simplify:

4y=-8-4

4y=-12

Then Divide both sides by the same factor:

4y=-12

4y÷4 =-12÷4

Simplify:

4y÷4 =-12÷4

y=-12÷4

y=-3

Your Answer:

A formula one race car will travel for 193.45 miles before changing its tires.

From the case, we know that:

tires diameter = 26 in.

1 set of tires = 150,000 rotations

12 in = 1 ft

1 miles = 5280 ft

We need to find the circumference of the tires before finding the total travel length.

Circumference = πd

Circumference = π(26in)

Circumference = 81.714 in.

We need to find the tires circumference in mile scale:

Circumference = 81.714 in : (12 inc/ft) : (5280 ft/miles)

Circumference = 0.0013 miles

Total travel distance = tires circumference x rotations

Total travel distance = 0.0013 x 150,000

Total travel distance = 193.45 miles

Therefore, the total distance Gabe will paddle is 2x + 400 meters. The exact value of x depends on the width of the river, which is not provided in the given information.

To find the total distance Gabe will paddle, we need to consider the distance he will travel from Q to P, then from P to R, and finally from R back to Q.

First, let's consider the distance from Q to P. Since Gabe will paddle in a diagonal line across the river, this distance can be calculated using the Pythagorean theorem.

The length of the bridge (PR) is given as 400 meters, which is the hypotenuse of a right triangle. The width of the river can be considered as the perpendicular side, and the distance Gabe will paddle from Q to P is the other side. Let's call this distance x.

Using the Pythagorean theorem, we have:

x^2 + (width of the river)^2 = PR^2

Since the width of the river is not given, we'll represent it as w. Therefore:

x^2 + w^2 = 400^2

Next, let's consider the distance from P to R. Gabe will paddle along a route beside the bridge, which means he will travel the length of the bridge (PR) again. So, the distance from P to R is also 400 meters.

Finally, Gabe will paddle back from R to Q along the shore. Since he will follow the shoreline, the distance he will paddle is equal to the distance from Q to P, which is x.

To find the total distance, we add up the distances:

Total distance = QP + PR + RQ

= x + 400 + x

= 2x + 400

The probability of the total being less than or equal to 4 when rolling two six-sided fair dice is 1/12.

To calculate the probability, we need to determine the favorable outcomes and the total number of possible outcomes. The favorable outcomes are the combinations that result in a total less than or equal to 4: (1, 1), (1, 2), (1, 3), (2, 1), (2, 2), (3, 1). The total number of possible outcomes is 6 x 6 = 36, as each die has 6 sides. Therefore, the probability is calculated as the ratio of favorable outcomes to total outcomes: 6/36 = 1/6. However, since we want the total to be less than or equal to 4, we exclude (3, 3) from the favorable outcomes.

Hence, the final probability is 5/36. The probability of the total being less than or equal to 4 when rolling two six-sided fair dice is 1/12 or approximately 0.0833.

b. Construct a boxplot:

A box plot is a visual representation of the distribution of a dataset. It shows the minimum, first quartile, median, third quartile, and maximum values of a data set. The box plot is drawn by representing the data in a box shape.

To construct a box plot, we need to determine the minimum, first quartile, median, third quartile, and maximum values of the given data set. Let's find them.

Minimum: The minimum value is the smallest number in the data set. Here, the minimum value is 35 kg.

First quartile: The first quartile is the middle value between the smallest value and the median of the data set. The median of the lower half of the data is the first quartile. Here, the median of the lower half of the data is 39 kg. Therefore, the first quartile is 39 kg.

Median: The median is the middle value of the data set. It divides the data set into two halves. Here, the median is the average of 44 kg and 47 kg. Therefore, the median is (44 + 47)/2 = 45.5 kg.

Third quartile: The third quartile is the middle value between the median and the largest value of the data set. The median of the upper half of the data is the third quartile. Here, the median of the upper half of the data is 51 kg. Therefore, the third quartile is 51 kg.

Maximum: The maximum value is the largest number in the data set. Here, the maximum value is 60 kg.

The equation that shows how the number of square feet the painter can cover, y, depends on the number of gallons of paint available, x is y = 400x.

An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.

Given that,

A house painter knows that he can cover 400 square feet with a gallon of paint.

Let x be the number of gallons of paint.

Let y be the number of square feet the painter can cover.

Number of square feet the painter can cover with 1 gallon of paint = 400

Number of square feet the painter can cover with x gallon of paint = 400x

So y = 400x

Hence the required equation is y = 400x

Step-by-step explanation:

Kiara's salary increased by 5% after a raise.

To find the percent increase in Kiara's salary, we need to calculate the difference between her new salary and her initial salary, and then express that difference as a percentage of her initial salary.

The initial salary is given as $48,000, and the new salary is $50,640. To find the difference, we subtract the initial salary from the new salary: $50,640 - $48,000 = $2,640.

To find the percent increase, we divide the difference by the initial salary and then multiply by 100: (2,640 / 48,000) * 100 = 5.5%. Therefore, Kiara's salary increased by 5.5% after the raise.
