How tall is a building that casts a 78-ft shadow when the angle of elevation of the sun is 30 degrees?
Answer: [tex]45.03\ ft[/tex]
Step-by-step explanation:
Given
The length of the shadow is 78 ft
the angle of elevation is [tex]\theta =30^{\circ}[/tex]
Suppose the height of the building is [tex]h[/tex]
From the figure, we can write
[tex]\tan 30^{\circ}=\dfrac{h}{78}\\\\h=78\tan 30^{\circ}\\\\h=45.03\ ft[/tex]

Jim's marble collection contains 20 marbles, including 4 pink marbles. What is the probability that a randomly selected marble will be a pink marble? Write your answer as a fraction or whole number.
Answer: 20%
Step-by-step explanation:
The probability that a randomly selected marble will be pink can be found by the formula:
= Number of pink marbles / Number of total marbles
= 4 / 20
= 20%
There is a 20% chance that if you pick a marble, it will be pink.

What is the slope of the line?
Answer:
4
Step-by-step explanation:
slope, m = (y₂ - y₁)/(x₂ - x₁)
plug in the values, and we get m = (3 - (-1))/((3 - 2) = 4
As x increases by 1, y increases by 4.
-1
Step-by-step explanation:
The slope of a line characterizes the direction of a line. To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points.

See unit circle for reference
A cone has a diameter of 8 units and a helght of 8 units. Its radius is____ its volume is ____ A cylinder with the same height and radius as the cone will have a volume of _____ cubic units. If a sphere has the same radius as the cylinder, Its volume is ____ the volume of the cylinder
Answer:
A cone has a diameter of 8 units and a height of 8 units. Its radius is 4units its volume is 134.04 cubic units. A cylinder with the same height and radius as the cone will have a volume of 402.12 cubic units. If a sphere has the same radius as the cylinder, Its volume is less than the volume of the cylinder.
radius = diameter / 2 = 8/2 =4units
[tex]volume \ of \ cone = \pi r^2 \frac{h}{3}[/tex] =134.04cubic units
[tex]volume \ of \ cylinder = \pi r^2h[/tex] = 402.12 cubic units
[tex]volume \ of \ sphere = \frac{4}{3}\pi r^3[/tex] = 268.08 cubic units

Answer:
a = 1.5
VW = 9 ft
Step-by-step explanation:
Since the tangent lines connect both circles, we know that the line VU and VX are congruent (equal). Thus, we can set them equal to each other and solve for a:
a + 4 = a² + 0.25 Set equal
a² - a = 3.75 Isolate a values
a² - a + 0.25 = 3.75 + 0.25 Complete the square
(a + 0.5)² = 4 Factor
a + 0.5 = 2 Simplify
a = 1.5
Now we need to calculate VW, but thats easy because its equal to TV, and since we know a, we can just plug it in:
((1.5) + 7.5) ft
9 ft

If 5 inches is added to both the length and the width of a rectangle, then the
perimeter is increased by -
Answer
the perimeter is increased by 5
Step-by-step explanation:
If 5 inches is added to both sides of the rectangle. Then the perimeter of the rectangle is increased by 20.
What is the perimeter of the rectangle?Let W be the rectangle's width and L its length.
The perimeter of the rectangle will be defined as the total length of all of its sides. So the rectangle's perimeter will be
Perimeter of the rectangle = 2(L + W) units
If 5 inches is added to both the length and the width of a rectangle.
Then the new perimeter of the rectangle is given as,
P = 2[(L + 5) + (W + 5)]
P = 2[L + W + 10]
P = 2(L + W) + 20
If 5 inches is added to both sides of the rectangle. Then the perimeter of the rectangle is increased by 20.
More about the perimeter of the rectangle link is given below.

Find the measure of angle B. Round your answer to the nearest whole number.
Answer: 37 degrees.
You use tan x to find the angle measure. So tan x = 9/12. When you plug it into a calculator, you get 36.86989765 so it rounds to 37.

Find the exact value of sin 0 if cos 0=-2/3 and 90º < 0 < 180°
Answer:
sin (theta) = [tex]\frac{\sqrt{5} }{3}[/tex]
Step-by-step explanation:
cos = adjacent side/hypotenuse
Then, in a right triangle the adjacent = 2 and the hypotenuse = 3
By the Pythagorean theorem, 3^2 = 2^2 + opposite side^2
9 - 4 = 5
opposite side = [tex]\sqrt{5}\\[/tex]
sin (theta) = [tex]\frac{\sqrt{5} }{3}[/tex]
An easier way is to find sin(arccos (-2/3) = [tex]\frac{\sqrt{5} }{3}[/tex]
Note: Remember that the sin is positive in the 2nd quadrant.

A passenger jet descends toward an airport. The graph models the descent of the
plane.
Answer:
D) -1200 ft
Step-by-step explanation:
The time passes through (0,20) and (5,14)
So, rate of descent= slope= 14-20/5-0= -6/5
so, -6/5 × 1000ft
= -1200 ft
So, rate of descent= -1200ft.

Which of the following is equivalent to x/x^2-1 + 4/x^2-6x-7?
a. x(x-7)+4(x-1)/(x+1)^2(x-7)
b. x+4/(x+1)^2(x-7)
c. x(x-7)+4(x-1)/(x+1)(x-1)(x-7)
d. x+4/(x+1)(x-1)(x-7)
Answer:
x(x-7)+4(x-1)/(x-1)(x+1)(x-7)
Step-by-step explanation:
Given the expression x/x²-1 + 4/x²-6x-7
Factorize x²-6x-7
x²-6x-7
= x²-7x+x-7
= x(x-7)+1(x-7)
= (x+1)(x-7)
Replace back into the expression given
x/x²-1 + 4/x²-6x-7
= x/x²-1 + 4/ (x+1)(x-7)
= x/(x+1)(x-1) + 4/(x+1)(x-7)
Find the LCM
= x(x-7)+4(x-1)/(x-1)(x+1)(x-7)
This gives the required expression

Answer: XVR: 125 ; RVS: 55 ; WVS: 125 ; RST: 110 ; RSV: 70
Step-by-step explanation:
XVR: XVR is equal to WVS (alternate angles), and WVS plus XVW equals 180° (definition of a straight line)
So, 180° - 55° = 125° (this is the measure of SVW, but remember, SVW is equal to XVR)
RVS: RVS is equal to XVW since they're alternate angles, so we know that RVS is equal to 55°
WVS: We already solved this in the beginning
RST: First, we need to find the measure of RSV. To find the measure of RSV, use the fact that a triangle adds up to 180°. We know that the angle RVS equals 55°, and that angle VRS is also equal to 55°. So, we can use this equation:
RSV = 180° - (55° + 55°)
RSV = 70°
Now that we know RSV = 70°, we can find RST
180 - (RSV + RST)
180 - (70° + RST)
RST = 110°
RSV: We already found this

what is the volume of this rectangular prism? (answer the picture)
Answer:
20.7 yd(rounded)
21 yd (exact)
Step-by-step explanation:
Since it goes 7 wide, do 7 x1/3 = 2.3 The 1/3rd comes from measurement given.
The length is 3 x 1/3 = 1 yd., so each level is 2.3 (repeating).
Since the height is 9, 9x2.3 = 20.7 yds (rounded)
If you want to be exact, 2.3333333333 x 9 = 21 (exact)
