Answer:

190.8 square inches

Step-by-step explanation:

The area of one of its triangular sides is given by A = bh/2 were b = base = 9 inches and h = perpendicular height = 6.1 inches.

A = bh/2. Since we have 4 triangular sides, the total area of its sides  A₁ = 4A = 4bh/2 = 2bh = 2 × 9 × 6.1 = 109.8 square inches.

The area of is base is the area of a square = 9² = 81 square inches.

So te total surface area is 109.8 square inches + 81 square inches = 190.8 square inches

4 days

Step-by-step explanation:

She recorded date for 16 days, and 1/4 of the days were clear blue skies.

One way to find this is to multiply 16 and 1/4

16*1/4=4

Another way is to first convert 1/4 to a decimal

1/4=0.25

Then multiply 16 and 0.25

16*0.25 =4

So, 4 out of 16 days had clear blue skies

Answer:

Please read the answer below

Step-by-step explanation:

The general form of a sinusoidal function is given by:

[tex]f(x)=Asin(\omega x)[/tex]   (1)

where A is the amplitude, and the period is given by:

[tex]T=\frac{2\pi}{\omega}[/tex]

The image of a function is the available values of the function f(x) in the domain of f(x). For sinusoidal function the image of f(x) is determined with the aid of the amplitude.  For example, in the case of (1), f(x) varies from -A to A.

Due to the information given above you have (the plots are attached below):

a)

[tex]f(x)=3sin(x)\\\\T=\frac{2\pi}{1}=2\pi\\\\Im\ f(x)=[-3,3][/tex]

b)

[tex]f(x)=1-sin(3x)\\\\T=\frac{2\pi}{3}\\\\Im\ f(x)=[0 \ ,2][/tex]

in the last case the first term of f(x) modifies the image of f(x) because the sinusoidal function is displaced to y=1.

c)

[tex]f(x)=-1+2sin(0.5x)\\\\T=\frac{2\pi}{0.5}=4\pi\\\\Im\ f(x)=[-3,1][/tex]

The original price of the game was £18. This is derived by understanding a 1/2 increase equates to a 50% increase, thus making £27 150% of the original price. To get the original price, divide £27 by 1.5.

To solve this problem, you need to understand that an increase of 1/2 equals a 50% increase. If the game price were £27 after increasing by 50%, that means £27 represents the original price plus an additional half (50%) of the original price, in other words, it represents 150% of the original price. We can set up the equation like this:

Original Price(1.5) = £27

To solve for the original price, we divide £27 by 1.5, resulting in £18.

So, the original price of the game was £18.

Step-by-step explanation:

Answer:

Out of 240,000 feet² of the field 62,800 feet² was being watered.

Step-by-step explanation:

We have a figure with 32 circles and diameter of each circle is 50 feet. We have to find how much area is being watered. Assuming that each circle represents the Area of the field which is being watered.

We can find the area of one circle and multiply that by 32 to find the area of all 32 circles. This will give us the area of the field that is being watered.

Since, radius is half of the diameter, the radius of each circle will be r = 25 feet.

Area of a circle is calculated as:

Area = πr²

Substituting the value of r = 25 and π = 3.14, we get:

Area of one circle = 3.14 x (25)² = 1962.5 feet²

Since area of 1 circle is 1962.5 feet² , area of 32 circles will be = 32 x 1962.5 = 62,800 feet²

The field is rectangular in shape with length = 600 feet and width = 400 feet.

Area of a rectangle is the product of its length and width. So area of the entire field will be:

Area of field = 600 x 400 = 240,000 feet²

This means, out of 240,000 feet² of the field 62,800 feet² was being watered.

The minimum unit cost to manufacture a car for the given quadratic cost function C(x) = 0.5x^2 - 130x + 17,555 is found by using the vertex formula. The x-coordinate of the vertex is -(-130)/(2*0.5) = 130, which yields the minimum unit cost of $9,105 when substituted back into the function.

To find the minimum unit cost for manufacturing cars in the given scenario, we need to analyze the cost function C(x) = 0.5x2 - 130x + 17,555. This is a quadratic function, which is parabolic in shape, generally either opening upwards or downwards. In this case, we have a positive coefficient for the x2 term, which means the parabola opens upwards and the vertex of this parabola will give us the minimum point or the minimum cost for producing cars.

The vertex of a quadratic function expressed in the form ax2 + bx + c can be found using the formula -b/(2a) for the x-coordinate of the vertex. In this case, a = 0.5, b = -130, so the x-coordinate of the vertex is -(-130)/(2*0.5) = 130. Plugging this value into the original function will give us the minimum unit cost C(130).

The calculation is as follows:

C(130) = 0.5 * (130)2 - 130 * (130) + 17,555

C(130) = 0.5 * 16,900 - 16,900 + 17,555

C(130) = 8,450 - 16,900 + 17,555

C(130) = 9,105

Therefore, the minimum unit cost to manufacture a car in this scenario is $9,105.

Answer:

47/62

Step-by-step explanation:

62 total games won 47 therefore 47/62

Final answer:

The fractional part of the games won by Betsy's softball team is 47/62, representing the number of games won out of the total games played.

Explanation:

To calculate the fractional part of the games won by Betsy's softball team, you need to divide the number of games won by the total number of games played. The team won 47 games and lost 15 games, giving a total of 47 + 15 = 62 games played.

The fraction representing the part of the games won is therefore 47/62. When simplified, this fraction may be reduced to a simpler form by finding the greatest common divisor and dividing both the numerator and the denominator by it. However, as 47 is a prime number and does not divide evenly into 62, the fraction can't be simplified further. Therefore, the fractional part of the games won by the team is 47/62.

There are 4 different flower boxes with different-size bases that can hold exactly 16 cubic feet of soil when using whole-number dimensions. These consist of dimension combinations of 1x1x16, 1x2x8, 1x4x4, and 2x2x4 feet.

Mrs. Wilton is planning a rectangular flower box that should have a volume of 16 cubic feet. To find how many flower boxes with different-size bases can hold exactly 16 cubic feet of soil, we need to find all the possible combinations of whole-number dimensions (length, width, and height) that when multiplied together equal 16 cubic feet. We must remember that volume is calculated as Length x Width x Height. Since 16 is the volume in cubic feet, we look for whole-number factors of 16.

Here are the possible whole-number dimension sets (in feet) for a volume of 16 cubic feet:

1 x 1 x 16 (Height can be 1, 16, or any factor of 16)

1 x 2 x 8 (Height can be 2, 8, or any factor of 16)

1 x 4 x 4 (Height can be 4 or any factor of 16)

2 x 2 x 4 (These dimensions are interchangeable)

Each of these dimensions gives a different base size for the flower box, and all ensure the volume is 16 cubic feet. Thus, there are 4 different flower boxes with different-size bases that will hold exactly 16 cubic feet of soil.

The required probability that the first pitch of the season uses one of your baseballs or one of your uncle's baseballs is 2/5.

Probability can be defined as the ratio of favorable outcomes to the total number of events.

There are 20 baseballs donated between you and your uncle and a total of 50 baseballs, so the probability that the first pitch of the season uses one of your baseballs or one of your uncle's baseballs is:

P(your baseball or uncle's baseball) = (number of your baseballs + number of uncle's baseballs) / total number of baseballs

= (8 + 12) / 50

= 20/50

= 2/5

Therefore, the probability that the first pitch of the season uses one of your baseballs or one of your uncle's baseballs is 2/5.

The probability that the first pitch of the season uses one of the baseballs donated by the student or their uncle is 2/5 or 40%.

To calculate the probability that the first pitch of the season uses one of your baseballs or one of your uncle's, we first need to figure out the total number of baseballs donated by you and your uncle. You donated 8 baseballs and your uncle donated 12 baseballs. Hence, together you both donated 8 + 12 = 20 baseballs.

Since there are a total of 50 baseballs donated, we can now calculate the probability. The probability of picking either one of your baseballs or one of uncle's baseballs is the total number of your combined baseballs divided by the overall total number of baseballs, which is 20/50. This can be simplified to 2/5 or 40%.

Therefore, the probability that the first pitch of the season uses one of the baseballs donated by you or your uncle is 2/5.

The coordinate of a point M, which divides the line segment AB internally in the ratio [tex]m_{1}:m_{2}[/tex] are given by:

                                 [tex]\frac{m_{1}x_{2}+m_{2}x_{1} }{(m_{1}+m_{2}) } ,\frac{m_{1}y_{2}+m_{2}y_{1} }{(m_{1}+m_{2}) }[/tex]

[tex]x[/tex] coordinate of point M is [tex]\frac{(2\times 8)+(1\times -1)}{(2+1)}[/tex] = [tex]\frac{(16-1)}{3} =\frac{15}{3} =5[/tex]

[tex]y[/tex] coordinate of point M is [tex]\frac{(2\times 15)+(1\times 2)}{(2+1)}[/tex] = [tex]\frac{30+2}{3} = \frac{32}{3}[/tex]

Hence, the coordinate of point M that divides the line segment AB is [tex](5, \frac{32}{3} )[/tex].

Answer:

Step-by-step explanation:

Let x represent the number of apples that she wants to buy.

The grocery store sells apples for $1 each and mangos for $0.50 each.

If Gabriella decided to buy 13 mangos, it means that the cost of buying x apples and 13 mangoes is expressed as

x + 13 × 0.5 = x + 6.5

If she buy at least 19 apples, it means that

x + 13 ≥ 19

x ≥ 19 - 13

x ≥ 6

Gabriella has $15 to spend. It means that

x + 6.5 ≤ 15

x ≤ 15 - 6.5

x ≤ 8.5

Therefore, the maximum number of apples that she can buy is 8

Final answer:

After purchasing 13 mangos, Gabriella can spend the remaining $8.50 on apples, which allows her to buy a maximum of 8 apples while also meeting the minimum requirement of 19 fruits in total.

Explanation:

If Gabriella decided to buy 13 mangos at $0.50 each, she would spend $6.50 on mangos. She has $15 to spend, so after buying the mangos, she would have $15 - $6.50 = $8.50 left. Since apples cost $1 each, Gabriella could buy a maximum of $8.50/ $1 per apple = 8 apples. However, she must buy at least 19 apples and mangos altogether. Since she has already bought 13 mangos, she would need to buy 19 - 13 = 6 apples to meet the minimum requirement. Therefore, the maximum number of apples she can buy is 8, which also satisfies the minimum quantity of fruit required.

The average total cost per hour of training is $70.5

Step-by-step explanation:

The form of the linear function is f(x) = m x + b, where

∵ The gym charges a $615 yearly fee for membership plus

   $50 for each hour of personal training

- That means the initial amount is 615 and the average rate is 50

∴ m = 50 dollars per hour

∴ b = 615 ⇒ fixed fee

- Substitute m and b in the form of the linear function

∴ c(x) = 50 x + 615, where c(x) is the cost per year for x

   training hours

∵ A member works with a personal trainer for 30 hours in a year

- That means x = 30

∴ x = 30

- Find the total cost of this year by substituting x by 30

∴ c(30) = 50(30) + 615

∴ c(30) = 1500 + 615

∴ c(30) = 2115

∴ The total cost of this year is $2115

To find the average cost per hour divide the total cost by the number of the training hours

∵ Average cost per hour = 2115 ÷ 30

∴ The average cost per hour = 70.5 dollars

∴ The average total cost per hour of training is $70.5

Based on the number of hours and the cost per hour of using the trainer, the average cost per hour is $70.50 per hour.

First find the total cost of using a trainer for 30 hours.

= Fixed membership cost + (Cost per hour x Number of hours)

= 615 + (50 x 30)

= $2,115

The total cost for the year is $2,115.

The average cost per hour will be:

= Total cost / Number of hours

= 2,115 / 30

= $70.50

In conclusion, the total average cost per hour is $70.50.
