I need help please.

To determine the average number of pies eaten by each participant in a contest with 9 participants and 46 pies, divide the total pies by the total participants. The result is approximately 5.11 pies per person, indicating they ate very evenly with most having eaten about 5 pies.

The question asks us to find out how many pies each person ate in a pie eating contest with 9 participants and 46 pies consumed. To calculate this, we divide the total number of pies by the number of participants. Here's the calculation:

Divide 46 pies by 9 participants to get the average number of pies per person.

The result is approximately 5.11 pies per person.

Since we can't have a fraction of a pie eaten in a real context, it suggests that participants ate either 5 or 6 pies each, if they are very evenly matched.

Therefore, the best description of how many pies each person ate, assuming they are very evenly matched, would be approximately 5 pies per person, with some participants possibly having eaten 6 pies to account for the total of 46 pies.

Answer:

V≈2770.88

Step-by-step explanation:

The volume of a cylinder that has a radius of 7 and a height of 18 is 2770.88.

In order to find the answer, you should use the formula πr²h.

R means radius and H means Height.

V=πr2h=π·72·18≈2770.88472

Answer:

V = 882pi units^3

or approximately

2769.48 units^3

Step-by-step explanation:

The column of a cylinder is given by

V = pi * r^2 * h

We know the radius is 7 and the height is 18

V = pi * 7^2 *18

V =pi *49 *18

V =882 pi

If we want an approximate answer, we can approximate pi by 3.14

V = 3.14 * 882

V =2769.48

Answer:

I'll be referring to this form: ax^2-bx+c

The 4x^2 is the rate that it goes up. If a is greater than 1, then that means the graph gets narrower from the parent function x^2. You can clearly see that in that graph.

The c is always the y-intercept. In this case, you can see that it's 7. The graph clearly shows 7 as it's y-intercept as well, so that matches well.

Sadly, I do not know how to compare the 8x into this situation without a calculator, but that information should be quite enough to see how that function is in that graph.

Answer:

34.4 cm

Step-by-step explanation:

The scale of the map is 1:500000

This means 1 cm in the map is equivalent to 500000 cm in actual.

So, first we need to convert the distance between the 2 towns in centimeters.

The distance between two towns is 172 km

172 km = 172 x 1000 meters = 172,000 meters

172,000 meters = 172,000 x 100 cm = 17,200,000 cm

500,000 cm in actual on the map = 1 cm

1 cm in actual on the map = [tex]\frac{1}{500000}[/tex] cm

17,200,000 cm in actual on the map will be = [tex]\frac{1}{500000} \times 17200000 = 34.4[/tex] cm

Thus, 172 km actual distance would be represented by 34.4 cm on the map

The distance between two towns on a map, with a scale of 1:500000 is 34.4 cm.

The question asks us to calculate the distance, in centimeters, between two towns on a map given the scale of the map is 1:500000, and the actual distance between the two towns is 172 km. First, we convert the actual distance from kilometers to centimeters by multiplying 172 km by 100,000 (since 1 km = 100,000 cm). This gives us 17,200,000 cm. Then, we use the map's scale to find the map distance. The scale 1:500000 means that 1 cm on the map equals 500000 cm in the real world. Therefore, we divide the real-world distance in centimeters by the scale factor (17,200,000 cm / 500000 = 34.4 cm). Thus, the distance between the two towns on the map is 34.4 cm.

Answer:

Step-by-step explanation:

Acceleration due to gravity is the rate at which an object changes its velocity due to the force of gravity.On Earth, the average acceleration due to gravity is -9.81 m/s².The acceleration due to gravity is ALWAYS negative.  Any object affected only by gravity (a projectile or an object in free fall) has an acceleration of -9.81 m/s², regardless of the direction.

The acceleration is negative when going up because the speed is decreasing.  The acceleration is negative when going down because it is moving in the negative direction, down.  Even at the top of the path where the instantaneous speed is 0 m/s, the acceleration is still -9.81 m/s². ...

Step-by-step explanation:

We can use the Pythagoras theorem to find the lengths of EF, FG, and HE

(GF)²=(ΔX)²+(Δy)²

(GF)²=(2--1)²+(4-3)²

=3²+1²

=10

GF=√10=3.16 units

(EF)²=(Δx)²+(Δy)²

=(2--1)²+(6-4)²

=3²+2²

=9+4

=13

EF=√13=3.61 units

(HE)²=(Δx)²+(Δy)²

=(-1--3)²+(6-3)²

=2²+3²

=4+9

=13

HE=√13=3.61 units

GH=(-1--3)=2 units

Perimeter =GF+EF+EH+HG

=3.16+3.61+3.61+2

=12.38 units

=12.4 units to 1 decimal place.

Answer:

the probability is the event is certain to happen

Step-by-step explanation:

Answer:

This event is certain to happen.

The probability is 1.

Step-by-step explanation:

Probability theory aims to explain the chance of an event occurring. In this case, there are 3 yellow balls, 4 blue balls and 8 red balls. The total of balls will be 3 + 4 + 8 = 15

If a random ball is removed, it can be any of three colors. The color that has the most balls will have a higher chance of being chosen from the 15 totals.

Likelihood of drawing a red ball: 8/15

Probability of a yellow ball: 3/15

Blue ball probability: 4/15

The question explains that only one ball will be removed and explains that there are only 3 colors. Therefore, when removing a ball, it will certainly be one of three colors.

This can be confirmed by adding the probability of each ball: 8/15 + 3/15 + 4/15 = 15/15 = 1

Thus, if a primary ball is removed, it will certainly be one of three colors. Moreover we can say that chance of being red is greater than being blue, which is greater than being yellow.

Answer:

The factors of 2q²-5pq-2q+5p are (2q-5p) (q-1)....

Step-by-step explanation:

The given expression is:

2q²-5pq-2q+5p

Make a pair of first two terms and last two terms:

(2q²-5pq) - (2q-5p)

Now factor out the common factor from each group.

Note that there is no common factor in second group. So we will take 1 as a common factor.

q(2q-5p) -1(2q-5p)

Now factor the polynomial by factoring out the G.C.F, 2q-5p

(2q-5p) (q-1)

Thus the factors of 2q²-5pq-2q+5p are (2q-5p) (q-1)....

The solution to the system of linear equations is (3, 0.5).

To solve the system of linear equations by graphing, we'll plot the two equations on the same set of axes and find the point of intersection, which represents the solution.

The solution is (3, 0.5). Confirming for the first equation: y = -3 - 7 = -10 and for the second equation: 3 + 2(0.5) = 4. The coordinates match both equations.

Answer:

[tex]x=4.459[/tex]

Step-by-step explanation:

We have the following equation

[tex]2^{(x-1)} =11[/tex]

To solve the function, apply the equation [tex]log_2[/tex] on both sides of the equation

[tex]log_2(2^{(x-1)}) =log_2(11)[/tex]

Remember that

[tex]log_b(b)^x =x[/tex]

So

[tex](x-1) =log_2(11)[/tex]

[tex]x =log_2(11) + 1[/tex]

Finally

[tex]x=4.459[/tex]

Answer:

x = 4.46

Step-by-step explanation:

We are to solve the following expression:

[tex]2^{(x-1)}=11[/tex]

Taking the natural logarithm of both sides of the equation to remove the variable from the exponent. to get:

[tex] ln ( 2 ^ { x - 1 } ) = l n ( 1 1 ) [/tex]

[tex] ( x - 1 ) l n ( 2 ) = l n ( 1 1 ) [/tex]

Applying the distributive property:

[tex]xln(2)-1ln(2)=ln(11)[/tex]

Solving for x to get:

[tex]x=\frac{ln(11)}{ln(2)} +1[/tex]

x = 4.46

Answer:

-2

Step-by-step explanation:

Before a dilation you have the point (x,y).

After a dilation of a scale factor of r you have (r*x,r*y).

Let's look at one pair of corresponding points.

A(-11,7)  and A'(22,-14)

We need to figure out what we can multiply to -11 to get 22.

We need to figure out what we can multiply to 7 to get -14.

Hopefully it is the same number or this isn't a dilation.

So to get from pre-image to image you need to multiply by -2 because -11*-2=22 and 7*-2=-14.

The scale factor is -2.

The dilation is this: (x,y)->(-2x,-2y)

The required scale factor is -2

The scale factor is a measure for similar figures, who look the same but have different scales or measures.

Let's consider one pair of corresponding points.

Clearly we need to multiply by -2.

This is applicable for all the points

So, the scale factor is -2.

Answer:

41.04 meters

Step-by-step explanation:

The questions which involve calculating the angles and the sides of a triangle either require the sine rule or the cosine rule. In this question, the two sides that are given are adjacent to each other the given angle is the included angle. The initial position is given by A. The tree is denoted as C and the fence post is denoted as B. Since the use of sine rule will complicate the question, it will be easier to solve this question using the cosine rule. Therefore, cosine rule will be used to calculate the length of BC. The cosine rule is:

BC^2 = AB^2 + AC^2 - 2*AB*AC*cos(BAC).

The question specifies that AC = 70 meters, BAC = 25°, and AB = 35 meters. Plugging in the values:

BC^2 = 35^2 + 70^2 - 2(35)(70)*cos(25°).

Simplifying gives:

BC^2 = 1684.091844.

Taking square root on the both sides gives BC = 41.04 meters (rounded to two decimal places).

Therefore, the distance between the point on the tree to the point on the fence post is 41.04 meters!!!
