Answer:
5 yd
Step-by-step explanation:
Use Pythagorean theorem,
Hypotenuse² = base² + altitude²
= 3² + 4²
= 9 + 16
= 25
Hypotenuse = √25 = √5*5 = 5 yd

Answer:
x = 18
Step-by-step explanation:
The "Angle Bisector" Theorem says that an angle bisector of a triangle will divide the opposite side into two segments that are proportional to the other two sides of the triangle.
So, 20/8 = (4x + 3)/30
8(4x + 3) = 20(30)
32x + 24 = 600
32x = 576
x = 18

1.
What is WY? Explain your reasoning.
Answer: WY = 27
Step-by-step explanation:
Due to WX being a Perpendicular Bisector WY = WZ
4x - 5 = 2x + 11
Add 5 to both sides
4x = 2x + 16
Subtract 2x from both sides
2x = 16
Divide by 2
x = 8
So 4x - 5 of x = 8
4*8 = 32 - 5 =27
Answer:
27
Step-by-step explanation:
WY = WZ because XZ = XY
[tex]2x + 11 = 4x - 5\\(2x + 11) - 11 = (4x - 5) -11\\2x = 4x - 16\\-2x = -16\\x = 8\\\\WY = 4x - 5\\WY = 4(8) -5\\WY = 32 - 5\\WY = 27[/tex]
A bag contains 12 red checkers and 12 black checkers. 1/randomly drawing a red checker 2/randomly drawing a red or black checker
Answer:
(I suppose that we want to find the probability of first randomly drawing a red checker and after that randomly drawing a black checker)
We know that we have:
12 red checkers
12 black checkers.
A total of 24 checkers.
All of them are in a bag, and all of them have the same probability of being drawn.
Then the probability of randomly drawing a red checkers is equal to the quotient between the number of red checkers (12) and the total number of checkers (24)
p = 12/24 = 1/2
And the probability of now drawing a black checkers is calculated in the same way, as the quotient between the number of black checkers (12) and the total number of checkers (23 this time, because we have already drawn one)
q = 12/23
The joint probability is equal to the product between the two individual probabilities:
P = p*q = (1/2)*(12/23) = 0.261

A plane is in route to drop off much needed medical supplies to a town. At an altitude of 6.4 miles, it located the town airport at an angle of depression of 7.9 degrees. How many horizontal miles left does the plane need to travel? round to the nearest tenth of a mile.
Answer:
The horizontal distance is 46.1 miles.
Step-by-step explanation:
Here, the given question can be explained by the sides of a right angled triangle. Let x represent the horizontal miles, then applying an appropriate trigonometric function;
Tan θ = [tex]\frac{opposite}{adjacent}[/tex]
Tan [tex]7.9^{o}[/tex] = [tex]\frac{6.4}{x}[/tex]
0.1388 = [tex]\frac{6.4}{x}[/tex]
x = [tex]\frac{6.4}{0.1388}[/tex]
= 46.1095
x = 46.1 miles
The plane needs to travel a horizontal distance of 46.1 miles.
Find the distance from (-6, 1) to (-3, 5).
Answer:
9.8 units
Step-by-step explanation:
distance = sqrt (x2 - x1)^2 + ( y2 - y1)^2
sqrt (-3 - (-6))^2 + (5 - 1)^2
sqrt (9)^2 + (4)^2
sqrt 81 + 16
sqrt 97

Use elimination to solve for x and y:
9x - 2y = 46
x + 2y = 14
Answer:
(6, 4 )
Step-by-step explanation:
Given the 2 equations
9x - 2y = 46 → (1)
x + 2y = 14 → (2)
Adding the 2 equations term by term will eliminate the y- term
10x + 0 = 60
10x = 60 ( divide both sides by 10 )
x = 6
Substitute x = 6 into either of the 2 equations and solve for y
Substituting into (2)
6 + 2y = 14 ( subtract 6 from both sides )
2y = 8 ( divide both sides by 2 )
y = 4
solution is (6, 4 )

Andy and Hershel folded the same- size square papers. Candy shaded 2 4 and Hershel shaded 1 2. Are the fractions equivalent? Explain.
Answer:
Yes, the fraction are equivalent
Step-by-step explanation:
Fraction shaded by candy = 2/4
Fraction shaded by Hershel = 1/2
If candy's fraction of 2/4 is reduced to it's lowest term ;
2 /4 = 1 /2 ; we also obtain the same fraction obtained by Hershel.
Hence, 2/4 is equivalent to 1/2

An airplane is at 32000 feet above sea level and the seeds at an average rate of 1000 feet per minute how many minutes will it take for the airplane to land at an airport 3000 feet above sea level
Answer:
29 minutes
Step-by-step explanation:
Let
x = number of minutes
y = the height of the airplane above sea level in feet
y = 32,000 - 1000x
y = 3,000
Therefore,
y = 32,000 - 1000x
3,000 = 32,000 - 1000x
3,000 - 32,000 = -1000x
-29,000 = -1,000x
x = -29,000 / -1,000
x = 29 minutes
it will take 29 minutes for the airplane to land at an airport 3000 feet above sea level

An element with a mass of 840 grams decays by 22.9% per minute. To the nearest minute, how long will it be until there are 70 grams of the element remaining?
Answer:10
Step-by-step explanation:believe me bro
To the nearest minute, it will be 10 minutes until there are 70 grams of the element remaining.
How to find the time it took for an element to decay to a certain mass?The time the element took to decay can be found by using the following formula:
[tex]F=P(1-r)^{t}[/tex]
Where:
F is the remaining mass.P is the original mass of the element.r is the rate at which the element is decaying.t is the time it took for the element to decay.We can find the answer by substituting the values.
[tex]F=P(1-r)^{t}\\\Rightarrow 70=840(1-0.229)^{t}\\\Rightarrow \frac{70}{840} =(1-0.229)^{t}\\0.0833=(1-0.229)^{t}\\t=9.56\\\approx10 \text{ minutes}[/tex]
Therefore, we have found that the element will take around 10 minutes to have 70 grams remaining.

A cylinder has a height of 16 meters and a diameter of 26 meters. What is its volume? Use ≈ 3.14 and round your answer to the nearest hundredth.
Answer:
V= 5224.96
Step-by-step explanation:
To find the volume for a cylinder, you need to use the formula
V=(pi)r^2h.
The question gives is the diameter. The radius is half of the diameter, so you would divide by 2.
16/2 = 8.
Now we plug in the numbers and solve.
V= (pi) 8^2(26)
V= (pi)(64)(26)
V=(pi)(1664)
V= 5224.96

As he already has money for the car.
A bar model is shown in the linked picture.
Since 2005, the amount of money spent at restaurants in a certain country has increased at a rate of 5% each year. In 2004, about 5430 billion was spent at
restaurants. If the trend continues, about how much will be spent at restaurants in 2014?
About 5 billion will be spent at restaurants in 2014 if the trend continues
(Round to the nearest whole number as needed.)
Answer:
8845 billion
Step-by-step explanation:
Since exponential growth is given by;
P = a( 1 + r)^t
Where;
P = amount spent after t years
r = exponential growth rate
t = time interval
2004 - 2014 is an interval of 10 years. If 5430 billion was spent in 2004 and the growth rate has been 5% each year, then;
P= 5430 * 10^9(1 + 5/100)^10
P = 8845 * 10^9
P = 8845 billion
