The value of x is 63.435, which is 60 round to the nearest tenth of a degree.
Given:
Height = 40 feet.
Distance =20 feet.
To find the value of x.
sinθ = hypotenuse/opposite.
cosθ = hypotenuse/adjacent.
tan θ = opposite/adjacent.
tan θ = 40/20 = 2
θ = tan ⁻(2) = 63.435
Therefore, 60 for x round to the nearest tenth of a degree.

At the local dairy farm, Kareem buys a 32-oz container of yogurt for $2.56. Jonah buys a 6-oz container of yogurt for $0.48. Are the cost, y, in dollars and the amount of yogurt, x, proportional? Explain. Write an equation to represent this relationship.
Answer:
Yes, the cost y in dollars and the amount of yogurt are proportional.
The equation is: y = 0.08x
Step-by-step explanation:
1. If y varies directly as x, you can write it as following: y = kx
Where k is the constant of proportionality.
2. Let's calculate the value of the constant of proportionality. If y = 2.56 and x = 32, you have:
y = kx
k = y/x
k = 2.56/32
k = 0.08
3. Then, the equation is: y = 0.08
4. Let's verify if they are directly proportional. Substitute which is the amount of yogurt bought by Jonah. The result must be $0,48:
y = 0.08 (6)
y = 0.48
5. They are directly proportional.
Find the area of the shaded sector. Round to the nearest hundredths place.
SR= 26 m
Answer: 315.45 m^2
Step-by-step explanation:
We know that the area of a circle is written as:
A = pi*R^2
Where:
pi = 3.14
R = radius of the circle.
In this case, we know that SR (the diameter) is equal to 26m
And the radius is half of the diameter, then:
R = 26m/2 = 13m
Now, in the image we can see that we have half of the circle shaded, the area of that part will be equal to half the area of a complete circle, then the area of that part is:
A = (1/2)*3.14*(13m)^2 = 265.33 m^2
We also can see that we have a small arc shaded.
The area of a given arc of an angle θ, is given by:
A = (pi*R^2)*(θ/360°)
Now we want to find the angle of this arc, that is the angle:
∠PQ
We know that:
∠SR = 180° (this is a straight line)
∠RQ = 73°
and i assume that:
∠PS = 73°
if we look at the image, we can see that we must have:
∠QR + ∠PQ + ∠SP = ∠SR
73° + ∠PQ + 73° = 180°
∠PQ = 180° - 2*73° = 34°
Then the area of the small arc is:
A' = (3.14*(13m)^2)*(34°/360°) = 50.12 m^2
The total shaded area is equal to the sum of the two areas we calculated, this is:
Total area = A + A' = 265.33 m^2 + 50.12 m^2 = 315.45 m^2

A building casts a shadow 100 m long. At the same time, a nearby pole 4 m high casts a shadow 8 m long. What is the height of the building? Round your answer to the nearest tenth, if necessary.
Answer:
50m
Step-by-step explanation:
Calculation for the height of the building
First step:
Let x represent the building height
Second step:
100m/8m = x/4
Third step is to Cross multiply:
100m(4) = 8x
400m= 8x
x=400m/8
x=50m
Therefore the height of the building will be 50m

Solve: x2 + 5x - 6= 0
A. -1, 6
B. 1, -6
C. -2, -3
D. 1,5
Answer:
Assuming that the x2 is x squared, B
Step-by-step explanation:
(1)(1) + 5(1) - 6 = 1 + 5 - 6 = 6 - 6 = 0
(-6)(-6) + 5(-6) - 6 = 36 - 30 - 6 = 6 - 6 = 0
Answer:
B
Step-by-step explanation:
Let's solve using factoring.
x²+5x-6=0
5 is the sum of the numbers, while -6 is their product.
Think: which two numbers add up to 5, but when multiplied, equal -6?
Those numbers are -1 and 6.
Now factor the polynomial:
(x-1)(x+6)=0
split into parts:
(x-1)=0
x-1=0
x=1
(x+6)=0
x+6=0
x=-6
So B

In the function y = x, if y = -8, what is x equal to?
Answer:
x = -8
Step-by-step explanation:
[tex]y =x[/tex]
If y = -8 — Substitute y = -8 in the equation.
[tex] - 8 = x[/tex]
Therefore, our x is -8 when y = -8
Answer:
x=-8
Step-by-step explanation:
Let's solve your system by substitution.
y=x; y=−8
Rewrite equations:
y=−8; y=x
Step: Solve y=−8 for y:
y=−8
Step: Substitute −8 for y in y=x:
y=x
−8=x
−8+−x=x+−x(Add -x to both sides)
−x−8=0
−x−8+8=0+8(Add 8 to both sides)
−x=8
-x/-1 = 8/-1
x=-8

Phil Lanthropist won a great deal of money in a contest. He gave 20% of his winnings to his parents, 25% of the remaining money to his children, and the remaining $900,000 to his favorite charity. What was the total number of dollars that Phil won?
Answer:
$1,636,363.64
Step-by-step explanation:
let x = total amount of money received
the total amount he received is 100%
Percent remaining after giving a percent of the money to family = 100% - 20% - 25% = 55%
This means that 55% of x = $900,000
To find the value of x, divide both sides by 55% or 0.55
x = $900,000 / 0.55 = $1,636,363.64
a. Identify all pairs of congruent angles in the diagram.
b. In the diagram, the measure of angle PQR = 130°, the measure of angle RQS = 84°, and the measure of angle TSR = 121°. Find the other angle measures in the diagram.
First off, we can see already that there are congruent symbols in the diagram (the single and double red lines correspond to the other one that looks alike to it)
Measure QRS is like measure QPT and since QRS = 84°, then QPT also equals 84°
Measure TSR is like measure STP and since TSR = 121°, then STP also equals 121°
