Answer: Nicole Kicked the ball Father by 22 feet than Tyrell.
Which girl's ball traveled the furthest, and by how far?The force of gravity caused the soccer ball to return to the girl.
By means of gravity, a planet or other body pulls items toward its center.
It is, in ideal circumstances, abiding by Newton's third law of gravitation and force.
Each action has a corresponding and opposing reaction.
So, when a boy kicks a ball and it comes back, that signifies he is abiding by the law.
Nicole kicked the ball 57 feet
Tyrel kicked the ball 35 feet
Nicole Kicked the ball Father by = 22feet
This is gotten by subtracting the distance Nicole kicked from that of Tyrel
=57 feet - 35feet = 22feet

Answer: By SSS, ΔSUR ≅ ΔTVR.
Step-by-step explanation:
This might be a longer method, but still here you go.
Given, ΔSTU ≅ ΔTSV
By CPCT, we have the following.
∠TUS / ∠RUS = ∠SVT / ∠RVT ---- 1
SU = TV ---- 2
SV = TU ---- 3
∠STU / ∠STR = ∠TSV / ∠TSR
Now, in the triangle TRS,
TR = SR ( ∠TSR = ∠STR) ---- 4
SV= TU
SV - SR = TU - TR (SR= TR)
UR = VR ---- 5
Now, we can use SSS in the triangles ΔSUR and ΔTVR
SU = TV (2)
SR = TR (4)
UR = VR (5)
Therefore, by SSS, ΔSUR ≅ ΔTVR.

You take one ball randomly from a bag with 10 yellow, 5 orange and 5 green balls. What is the probability that you don’t take a yellow ball.
0
1
1/2
Can not be determined
Answer: The probability of not taking a yellow ball can be found by using the formula:
Probability of event A = (Number of favorable outcomes) / (Total number of outcomes)
In this case, the event of not taking a yellow ball is the favorable outcome, and the total number of outcomes is the total number of balls in the bag, which is 10 yellow, 5 orange, and 5 green balls. So, the total number of outcomes is 20.
The number of balls that are not yellow is 5 orange + 5 green = 10.
So, the probability of not taking a yellow ball is
Probability of not taking a yellow ball = (Number of non-yellow balls) / (Total number of balls) = 10/20 = 1/2
So the answer is 1/2.

Using rectangles whose height is given by the value of the function at the midpoint of the rectangle's base (the midpoint rule), estimate the area under the graph of the following function, using two and then four rectangles.
[tex]y=81-x^2[/tex] between [tex]x=-9[/tex] and [tex]x=9[/tex]
The estimates of the area under the curve using rectangles is given as follows:
Two rectangles: 729 units squared.Four rectangles: 911.25 units squared.How to approximate the area?The area under a curve is approximated using the definite integral of the function that defines the curve within it's bounds.
As it is specified that the area should be approximated using rectangles, a Left Riemann Sum will be used to approximate the area.
With two rectangles, the Delta value is obtained as follows:
[tex]\Delta_x = \frac{9 - (-9)}{2}[/tex]
[tex]\Delta_x = 9[/tex]
The values of x are obtained with the rule presented as follows:
[tex]x_i = a + \Delta_x(i - 1)[/tex]
With two rectangles, the values are given as follows:
-9 and -9 + 9 = 0.
The numeric values are given as follows:
x = -9: 81 - (-9)² = 0.x = 0: 81 - 0² = 81.The definite integral is given as follows:
[tex]\sum_{i = 1}^n = \Delta_xf(x_i)[/tex]
Hence the result is of:
9 x 81 = 729 units squared.
With four rectangles, the Delta value is given as follows:
[tex]\Delta_x = \frac{9 - (-9)}{4} = 4.5[/tex]
Hence the values of x are:
x = -9, x = -4.5, x = 0, x = 4.5.
The numeric values are:
x = -9: 81 - (-9)² = 0.x = -4.5: 81 - (-4.5)² = 60.75.x = 0: 81 - 0² = 81.x = 4: 81 - (-4.5)² = 60.75.Hence the result of the integral is given as follows:
4.5(60.75 + 81 + 60.75) = 911.25 units squared.

The distribution of hourly rates of registered nurses in a large city has mean $31 and standard deviation $5.
a) What is the distribution of the sample mean based on a random sample of 100 registered nurses in the city?
b) Find the probability that the average hourly rate of the 100 nurse sample exceeds $31.50.
a) The distribution of sample means of 100 registered nurses in the city is approximately normal, with mean $31 and standard deviation of $0.5.
b) The probability that the average hourly rate of the 100 nurse sample exceeds $31.50 is of: 0.1587 = 15.87%.
How to obtain probabilities using the normal distribution?The z-score of a measure X of a variable that has mean symbolized by [tex]\mu[/tex] and standard deviation symbolized by [tex]\sigma[/tex] is obtained by the rule presented as follows:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score represents how many standard deviations the measure X is above or below the mean of the distribution, depending if the obtained z-score is positive or negative.Using the z-score table, the p-value associated with the calculated z-score is found, and it represents the percentile of the measure X in the distribution.By the Central Limit Theorem, the sampling distribution of sample means of size n is approximately normal and has standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].The parameters for this problem are given as follows:
[tex]\mu = 31, \sigma = 5, n = 100, s = \frac{5}{\sqrt{100}} = 0.5[/tex]
The probability that the average hourly rate of the 100 nurse sample exceeds $31.50 is one subtracted by the p-value of Z when X = 31.5, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem:
[tex]Z = \frac{X - \mu}{s}[/tex]
Z = (31.5 - 31)/0.5
Z = 1
Z = 1 has a p-value of 0.8413.
1 - 0.8413 = 0.1587 = 15.87%.

How to divide two fractions?The division of two fractions is given by the multiplication of the first fraction by the inverse of the second fraction.
The first fraction for this problem is given as follows:
(4x² + 6)/(x - 2).
The second fraction for this problem is given as follows:
(10x² + 15)/(x² - 4).
Applying the subtraction of perfect squares, we have that:
x² - 4 = (x + 2)(x - 2).
Then the division of the two fractions is given as follows:
(4x² + 6)/(x - 2) x [(x + 2)(x - 2)/(10x² + 15)]
Simplifying the x - 2 terms, we have that:
[tex]\frac{(4x^2 + 6)(x + 2)}{10x^2 + 15}[/tex]
No values must be excluded, as the denominator would be never zero, as:
10x² + 15 = 0
10x² = -15.
x² is always positive, hence 10x² will never be equals to -15.

Find the distance between the two points rounding to the nearest tenth (if necessary)
(3,2) and (6,0)
Answer:
The distance between two points in the coordinate plane can be found using the distance formula, which is:
distance = √((x2 - x1)^2 + (y2 - y1)^2)
In this case, the two points are (3,2) and (6,0), so we can plug in the values to get:
distance = √((6 - 3)^2 + (0 - 2)^2)
distance = √((3)^2 + (-2)^2)
distance = √(9 + 4)
distance = √13
So the distance between the two points (3,2) and (6,0) is approximately 3.61 units.

Gianna drives 5 miles in 10 minutes. If she drove three hours in total at the same rate,
how far did she go?
Before you try that problem, answer the question below.
How many minutes did Gianna drive in total?
Gianna is 90 miles far away in 3 hours of driving.
She drove in total of 180 minutes.
What is speed?The speed can be defined as the rate at which an object covers some distance. Speed can be measured as the distance traveled by a body in a given period of time. The SI unit of speed is m/s.
Given,
Gianna drives 5 miles in 10 minutes
Speed per minute = 5/10 = 0.5 miles/minute
Gianna drove in total for 3 hours
1 hour = 60 minutes
3 hours = 60 × 3 = 180 minutes
Distance Gianna drove in 180 minutes = speed per minute × time
= 0.5 × 180
= 90 miles
Hence, Gianna drove 90 miles in 3 hours, 180 minutes is total time she drove.

Isosceles triangle OPQ has legs OP = OQ, base PQ = 2 , and POQ = 45. Find the distance from O to PQ.
In other words, how can you find the hight of an isosceles triangle with the base and angles.
The height of the isosceles triangle OPQ is given as follows:
2.41.
What is isosceles triangle?An isosceles triangle is a triangle that has two equal side lengths, hence it also has two equal angle measures.
The top angle is of 45º, while the sum of the internal angles of the triangle is of 180º, hence the base angles are obtained as follows:
2x + 45 = 180.
2x = 135
x = 135/2
x = 67.5º.
Then the height is obtained considering a right triangle, in which the height is opposite to an angle of 67.5º, while the adjacent side has length of 1, which is half the base.
Applying the tangent of the angle of 67.5º, the height is obtained as follows:
tan(67.5º) = h/1
h = tan(67.5º)
h = 2.41.
