Solve for a. Help please!
Answer:
a = √63
Step-by-step explanation:
Pre-SolvingWe are given a right triangle (notice the right angle).
We know that the hypotenuse (the side opposite of the right angle) is 12.
We also know that one leg (a side that makes up the right angle) is 9, and that the other one is a.
We want to find what a is.
SolvingWe can use the Pythagorean Theorem to help us find a.
The Pythagorean Theorem says a² + b² = c², where a and b are the legs and c is the hypotenuse.
Since we already know the values of the legs and hypotenuse, we can substitute these values in the theorem, but let's first label the values of everything to avoid confusion / mistakes.
a = a
b = 9
c = 12
Now, plug into the formula.
a² + 9² = 12²
Simplify:
a² + 81 = 144
Subtract 81 from both sides
a² = 63
Square root both sides to get the value of a.
a = √63
if wx = 14 and wr= 8, find RZ
The length of RZ is obtained as follows:
RZ = 11.5.
How to obtain the length of RZ?From the kite given by the image at the end of the answer, the segment lengths are given as follows:
WX = 14.WR = 8.Segments WX and WZ are congruent, hence segment WZ has the length given as follows:
WZ = 14.
Then the length of RZ is obtained considering a right triangle, for which:
RZ = x and WR = 8 are the side lengths.WZ = 14 is the hypotenuse.The Pythagorean Theorem states that the length of the hypotenuse squared is equals to the sum of the lengths squared of the sides.
Considering the Pythagorean Theorem, the length RZ is obtained as follows:
x² + 8² = 14².
[tex]x = \sqrt{14^2 - 8^2}[/tex]
x = 11.5.
RZ = 11.5.
Missing InformationThe problem is given by the image presented at the end of the answer.

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

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.

The change between outputs found by dividing one output by its previous output is called output elasticity.
What is output elasticity?
Output elasticity is defined as the division of change in output by change in input which is the previous output.
General, elasticity is a concept that is used to measure the change in the aggregate quantity demanded of a good or service in relation to price movements of that good or service.
A product is considered to be elastic if the quantity demand of the product changes more than proportionally when its price increases or decreases.

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.

Evaluate the expression.
3√4
Answer: 6
Step-by-step explanation:
Let's start by rewriting the expression. Essentially, this is asking us for 3 * (times) √4 (square root of four).
Now, we can solve √4. Since we know that 2*2 = 4. That means that 2² = 4, so essentially, if we take the square root of 4, we will get back to two.
Now, we can solve the rest: 3 * 2 = 6
In the end, 3√4 = 6. Hope this helps!

You can hire someone without experience for $13 per hour or someone with experience for $19 per hour. You believe the
experienced person increases the sales per customer by $3. Each person handles about 12 customers per hour. Should you hire the
experienced person?
a) Yes
b) No
Answer:
a) Yes
The experienced person costs more per hour, but also increases sales per customer. To determine if it is more cost-effective to hire the experienced person, you would need to calculate the net gain or loss from hiring them.
You can do this by multiplying the increase in sales per customer by the number of customers per hour, and comparing that to the difference in hourly wages.
(12 customers/hour * $3/customer) - ($19/hour - $13/hour) = $36/hour - $6/hour = $30/hour
Since the net gain is positive, it is more cost-effective to hire the experienced person.

The area of the triangle KLM is found using Heron's formula as:
A = 60 in².
Explain the Heron's formula.The semi-perimeter of such a triangle, wherein area needs to be calculated, is represented by the letter s in Heron's formula. The total of the triangle's three sides, divided by two, is the semi-perimeter.S = (a+b+c)/2
where a, b, and c are the triangle's three sides.
The sides of the triangle KLM are:
Let KL : a = 13 in.Let LM : b = 13 in.Let KM : c = 10 in.Then,
Semi perimeter s = a + b + c / 2
s = (13 + 13 + 10)/ 2
s = 18 in
Thus,
s - a : 18 - 13 = 5
s -b : 18 - 13 = 5
s - c : 18 - 10 = 8
By Heron's formula;
area of triangle KLM = √(s - a)(s -b)(s - c)
A = √18*5*5*8
A = 60
Thus, the area of triangle KLM is found using Heron's formula as:
A = 60 in².

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.

The correct option regarding the quotient of the two fractions is given as follows:
B. [tex]\frac{(4x^2 + 6)(x + 2)}{10x^2 + 15}[/tex], no values must be excluded.
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.
