1 find and interpret the y-intercept.
2find and interpret the x-intercept.
3how many grams of fiber does an orange contain?
4how many grams of fiber does an apple contain?
5is it possible for the package to contain 15 apples? explain.

Answers

The y intercept is the value of y when x = 0.

Similarly, the x intercept is the value of x when y = 0.

To find each of these, we separate the equation as shown in the attached image. After solving for x and y, we find that the y intercept is 11 and the x intercept is 22. (The image will show the process of finding each).

For part e, we substitute 15 in for x. So instead of putting x in the equation, we will put 15 and solve for y. After solving, we see that y will equal 3.5.

However, since we cannot have a "half apple" in the package, we see that it is not possible to have 15 apples in the package.

Please Help!!!!!!!! Only Circled Questions!!!!!!!!!!! Show all Steps

Hello!

I'll solve the first two questions for you and show you how to do them step by step!

4.

We must use a certain formula to find the volume of a cylinder. The formula is:

V = pi * r^2 * h

We already have that information!

Pi = approximately 3.14

Radius = 7.5 in

Height = 3.6 in

Substitute:

(Make sure ro solve it step by step, rather than do it all at once)

V = 3.14 * 7.5^2 * 3.6

V = 176.625 × 3.6

V = 635.85

Rounded to the nearest cubic unit, the volume of this cylinder is 636 inches cubed.

**Don't forget to write a small 3 above inches to indicate that it is cubed!

5.

Aha! This time they haven't given you the radius, but the diameter.

Since the radius is half of the diameter, we must divide the diameter by 2 to find it.

r = d ÷ 2

r = 28 ÷ 2

r = 14 cm

Like the previous question, we have enough information to solve this! We'll use the same formula to calculate the volume of this cylinder.

V = pi * r^2 * h

Pi = Approximately 3.14

Radius = 14 cm

Height = 5 cm

Substitute:

V = 3.14 * 14^2 * 5

V = 615.44 * 5

V = 3,077.2 cm cubed

Rounded to the nearest cubic unit, the volume of this cylinder would be 3,077 centimetres cubed.

REMINDERS:

Use the SAME formula for all of the other questions regarding volume of a cylinder. The formula fof volume is:

V = pi * r^2 * h

Make sure you write the small 3 above it!

Karim sent a chain email to 10 of his friends. The number of people who got the email increases by a factor of 1.4 every week. Write an expression that best represents the
number of people who got the email after three weeks.

Answers

Final answer:

The number of people who got the email after three weeks can be calculated using the formula: F = 10 * (1.4)^t, where F represents the number of people, 10 represents the initial number of friends, 1.4 represents the factor of increase, and t represents the number of weeks. After substituting t = 3, we find that approximately 27 people will have received the email after three weeks.

Explanation:

To represent the number of people who got the email after three weeks, we can use the formula:

F = 10 * (1.4)^t

Where:

F represents the number of people who got the email10 represents the initial number of friends Karim sent the email to1.4 represents the factor by which the number of people increases each weekt represents the number of weeks

Substituting t = 3 into the formula, we can calculate the number of people who got the email after three weeks.

F = 10 * (1.4)^3 = 10 * 2.744 = 27.44

Therefore, after three weeks, approximately 27 people will have received the email.

The correct expression is:

(B) [tex]$10 \cdot 1.4^6$[/tex]

Sure, let's break it down step by step:

1. Initial number of people who received the email: Karim sent the email to 10 friends, so initially, [tex]$10$[/tex] people received it.

2. Factor by which the number of recipients increases each week: The number of recipients increases by a factor of [tex]$1.4$[/tex] each week.

3. Number of people who received the email after 1 week: To find this, we multiply the initial number of recipients by the factor for 1 week, which is [tex]$10 \times 1.4 = 14$.[/tex]

4. Number of people who received the email after 2 weeks: Now, we take the number of recipients after 1 week (14) and multiply it by the factor for another week, [tex]$1.4$[/tex], giving us [tex]$14 \times 1.4 = 19.6$[/tex]. Since we can't have a fraction of a person, we round this up to the nearest whole number, which is [tex]$20$.[/tex]

5. Repeating this process for 6 weeks: We continue this process for each additional week until we reach the 6th week.

6. General formula for the number of recipients after [tex]$n$[/tex] weeks: After [tex]$n$[/tex] weeks, the number of recipients can be calculated using the formula:

[tex]\[10 \times 1.4^n\][/tex]

So after 6 weeks, the expression becomes:

[tex]\[10 \times 1.4^6\][/tex]

7. Final Answer: The correct choice is (B) [tex]$10 \times 1.4^6$.[/tex]

The correct question is:

Karim sent a chain email to 10 of his friends. The number of people who got the on: il increases by a factor of 1.4 every week.

Which expression gives the number of people who got the email after 6 weeks?

Choose 1 Anwer:

(A) [tex]$(10 \cdot 1.4)^6$[/tex]

(5) [tex]$10 \cdot 1.4^6$[/tex]

(D) [tex]$(10+1.4) \cdot 6$[/tex]

If eight people sat at a round dinner table and each person had to shake everyone else’s hand once how many handshakes will take place

Answers

Each person shakes 7 hands, but once you count the handshake between A and B, you don't need to count the handshake between B and A. There are a total of 8*7/2 = 28 handshakes.

Another way to look at it is
7 +6+5 +4 + 3 + 2 + 1 = 28

This problem is like the shaking hands problem having to do with what happens at the end of a hockey team. The winners sometimes stay on the ice and the first player goes down the line and "High Fives" all the other members of the team.

He's done so he goes to the dressing room. No more high 5s for him.
Next the second player does the same thing. Then he leaves the ice and so on down the to the last two players when one high fives the other.

Done.

Your problem is exactly the same.

anna has a 10 foot long ladder that she is going to rest against a vertical wall along the bottom of a window still that is 8.5 feet above the ground. The safety code recommends that the angle the ladder makes with the ground be no greater than 65 degrees. Will the ladder be safe resting on the window still? Draw a diagram and show work to support your answer

Answers

As you can see in the picture, the ladder leaning against the wall makes a right triangle with the sides being the wall, the ground and the ladder. The ladder is opposite the right angle and so is the hypotenuse (the longest side of the triangle). The angle between the ladder and the ground is labeled a.

We know the height of the ladder (10 feet) and also the height off the ground of the windowsill (8.5 feet). That second side is opposite the angle a. So, when we consider angle a we know the length of the side opposite and of the hypotenuse.

Recall the sin of an angle can be found by using (opposite/hypotenuse).

So we have: sin a = 8.5 / 10. That is, sin a = .85
We are looking for the angle whose sin is .85 and can find this using the inverse sin function.

[tex] sin^{-1}.85=a [/tex]
a is approximately 58.211669 degrees which is less than the 65 degrees and so safe.

Just to be on the safe side, I remind you that your calculator must be in degrees (not radians) to do this problem.

What value of x would make rq tangent to Circle P at point Q?

Answers

If Q is tangent to circle P, that means that it is perpendicular to the radius at the point of tangency. This means that ΔPRQ would be a right triangle. We can use the Pythagorean theorem to solve this.
9² + 12² = (x+9)²
We use x+9 because the unknown segment x would combine with the radius, 9, to give that side of the triangle (the hypotenuse).
81 + 144 = (x+9)(x+9) ---- remember that squared means multiplied by itself
225 = (x+9)(x+9)
Multiply the right hand side:
225 = x² + 9x + 9x + 81
225 = x² + 18x + 81
Subtract 225 from both sides:
225 - 225 = x² + 18x + 81 - 225
0 = x² + 18x - 144
Use the Quadratic Formula to solve:
[tex]x=\frac{-b \pm \sqrt{b^2-4ac}}{2a} \\ \\x=\frac{-18 \pm \sqrt{18^2-4(1)(-144)}}{2(1)} \\ \\x=\frac{-18 \pm \sqrt{324--576}}{2} \\ \\x=\frac{-18 \pm \sqrt{324+576}}{2} = \frac{-18 \pm \sqrt{900}}{2}[/tex]
This gives us
[tex]x=\frac{-18 \pm 30}{2} = \frac{-18+30}{2} \text{ or } \frac{-18-30}{2}[/tex]
Since -18 - 30 = -48, and a negative number doesn't make sense in this situation, we have
x = (-18+30)/2 = 12/2 = 6.

The value of x cannot be negative, hence the value of x would make rq tangent to Circle P at point Q is 6

From the given circle geometry, since the line PQ is perpendicular to QR, hence the triangle PQR is a right-angle triangle.

Given the following from the geometry;

Using the pythagoras theorem;

[tex]c^2=a^2+b^2\\(9+x)^2=9^2+12^2\\81+18x+x^2=81+144\\x^2+18x+81-225=0\\x^2+18x-144=0\\[/tex]

Factorize the result to have;

[tex]x^2+24x-6x-144=0\\x(x+24)-6(x+24)=0\\(x-6)(x+24) =0\\x=6 \ and \ -24\\[/tex]

You are working as an apprentice for the bksb Newcastle Arena. When bands play at the arena the money made from ticket sales is split in an agreed ratio. When Phillip Cage played, £21,000 was split at a ratio of 2:5 between the arena and Phillip Cage. How much money did the arena make from Phillip Cage’s concert?

Answers

2x + 5x = 21000
7x = 21000
x = 21000/7
x = 3000

That means the money was split up

2 * 3000 = 6000
5 * 3000 = 15000

The arena got the 2 part of the ratio.
The arena got 6000 pounds. I don't have that L on my keyboard.

Final answer:

The arena therefore made £6,000 from Phillip Cage's concert.

Explanation:

To find the amount of money the arena made from Phillip Cage's concert:

Calculate the total parts in the ratio: 2 + 5 = 7 parts.Divide the total money by the total parts: £21,000 / 7 = £3,000 per part.Finally, multiply the arena's share of parts (2 parts) by the value of each part: £3,000 x 2 = £6,000.

Using a standard shoe size chart, the foot length for a size 10 1/2 shoe is approximately 11.1 inches when rounded to the nearest tenth of an inch.

To determine the length of the foot for a person who wears a size 10 1/2 shoe to the nearest tenth of an inch, we reference a standard shoe size chart. Shoe sizes are an approximation of the foot length they are intended to fit, with different increments representing each half-size increase. For a size 10 shoe, the approximate length is given as around 10.9 to 11 inches. Considering half sizes add approximately 1/6 of an inch, a size 10 1/2 would be approximately 11.1 inches long when measured accurately. However, shoe size to foot length can vary slightly by manufacturer, so this is a general estimate.

the answer will be 62

Solution:

we are given with a dot plot where we can see that the number of visitors.

we have been asked to find the median of the data set.

From the data plot , we can write the data set as below

56,56,56,56,58,58,60,62,62,62,63,65,65,68,68.

Here the data set is already arranged in the ascending order.

Now if the number of data points in the data set is odd then middle number is the median.

If the number of data points in the data set is even then the sum of middle two divided by 2 gives the median.

Here the number of data points in the data set is odd.

So the median is 8th value from any side.

Hence the median of the given data set is 62.

The statement that at least one of the kids won exactly 5 coloring contests is false based on the given information. The median of a dataset is the middle value when the numbers are arranged in order. However, knowing the median is 5 does not necessarily mean any of the values in the dataset are 5. It only indicates that half of the kids won more than 5 contests, and half won fewer. The range of 6 tells us the difference between the highest and lowest values but does not provide specific information about any of the kids winning exactly 5 contests.

The given data does not contain enough information to accurately say whether a kid won exactly 5 contests or not, thus making the initial claim not necessarily true.

A total of 757 tickets were sold for the school play. They were either adult tickets or student tickets. There were 57 more student tickets sold than adult tickets. How many adult tickets were sold?

Answers

350 adult tickets were sold

Final answer:

To find the number of adult tickets sold, a system of equations is created based on the total tickets sold (757) and the fact that there were 57 more student tickets sold. Solving for x gives us 350 adult tickets.

Explanation:

How to Determine the Number of Adult Tickets Sold

To determine how many adult tickets were sold for the school play when there is a known total of 757 tickets and that 57 more student tickets were sold than adult tickets, we can set up a system of equations to solve for the number of adult and student tickets. Let's let x represent the number of adult tickets, and x + 57 represent the number of student tickets since there were 57 more student tickets sold than adult tickets.

Based on the total number of tickets sold, the following equation represents this relationship:

x (adult tickets) + x + 57 (student tickets) = 757

Combining the like terms gives us:

2x + 57 = 757

Subtracting 57 from both sides gives us:

2x = 700

Dividing both sides by 2 gives us:

x = 350

So, the number of adult tickets sold is 350.
