Answer:
x = 1.5
Step-by-step explanation:
Here, we want to get what x is
To arrive at the answer for x, we are going to use an important circle theorem equation
We have this as;
lh^2 = lj * lk
from the question;
lh = 1
lj = 0.5
lk = (0.5 + x)
Thus;
1^2 = 0.5(0.5 + x)
1 = 0.25 + 0.5x
0.5x= 1-0.25
0.5x= 0.75
x = 0.75/0.5
x = 1.5
The equation h=4+7t can be used to determine the height of a flag (h, In feet) after t seconds.
A) What Is the starting height of this flag?
B) What Is the speed of this flag?
Answer:
4
7
Step-by-step explanation:
Part A
The starting height of the flag occurs when t = 0
h = 4 + 7*0
h = 4
So the starting height is 4 feet.
Part B
The speed of the flag is the slope of the line which is 7. So every second the flag is ascending, the flag goes up 7 feet per second.
52. A 33-tt ladder leans against a building so that the angle between the ground and the ladder is 80". How high does the
ladder reach up the side of the building?
9514 1404 393
Answer:
32.5 ft
Step-by-step explanation:
The length of the side opposite the given angle is found using the sine relation:
Sin = Opposite/Hypotenuse
height on building = (33 ft)·sin(80°) ≈ 32.5 ft
The ladder reaches about 32.5 feet up the side of the building.
_____
Additional comment
The maximum angle compliant with OSHA safety rules is 75.5°.

Answer:
4250 children.
Step-by-step explanation:
72 - 38 = 34
34 degrees = 578 people
/34 /34
1 degree = 17 people
72 + 38 = 110
360 - 110 = 250
17 * 250 = 4250 children.
A cylinder of clay has a radius of 6 cm and a height of 12 cm. If this clay is made into congruent cones with a radius of 3 cm and a height of 8 cm, how many cones could be made with all of the clay? Show work to support how you determined your answer.
Answer:
So we want to know how much clay did Joseph add after he built the cone. So the formula for the volume of the cone is V=(1/3)*pi*r^2*h where r is the radius and h is height. We know h1=12cm and r1=6cm, r2=6cm and h2=18 cm. So to get the amount of added clay Va we simply subtract the volume of the clay of the first cone V1 from the volume of the second cone V2: Vd=V2-V1=(1/3)*pi*(r1^2)*h1 - (1/3)+pi*(r2^2)*h2. Va=678.24 cm^3-452.39 cm^3= 266.08 cm^3.

Which of the following functions has a range of f(x) 2 2?
O A. f(x) = 2x + 8
OB. f(x) = 4x + 2
O C. f(x) = (x - 1)2 + 2
O D. f(x) = -x2 + 2
Answer:
A.f(x)=2x+8
22=2x+8
-8+22=2x
14/2=2x/2
7=x
x=7
B.f(x)=4x+2
22=4x+2
-2+22=4x
20/4=4x/4
5=x
x=5

Find h.(Type your answer in simplest radical form)
9514 1404 393
Answer:
(x, y) = (8, 2)
Step-by-step explanation:
Using the geometric mean rules for this geometry, we have ...
h = √(4·32) = 8√2
and also ...
a = √(4·36) = 12
b = √(32·36) = 24√2
For the problem at hand, ...
h = 8√2 = x√y ⇒ x = 8, y = 2
What steps transform the graph of y = x? to y = -(x + 3)2 + 5?

Answer:
88 ft²
Step-by-step explanation:
Find the area of the shaded region:
8x16= 128
Find the area of the un-shaded region:
5x4=20
20x2 regions= 40 ft² total
since the unshaded region is excluded from the shaded region subtract the area of the shaded region by the area of the unshaded region
128-40= 88
A= 88 ft²

Step-by-step explanation:
. A movie company sells DVDs on line. Each
DVD costs $9.95. No matter how many you
order, the shipping charge is $3.59. Your most
recent order came to a total of $33.44.
Please help on all questions in picture
Multiply by cost of a dvd by the number of dvds bought ( x) and add the shipping charge.
A) 33.44 = 9.95x + 3.59
Subtract 3.59 from both sides.
29.85 = 9.95x
Divide both sides by 9.95
X = 29.85/9.95
X = 3
They bought 3 dvds.
B) 33.49-3.59 = 29.85
29.85/9.95 = 3
C) the steps were the same but solving arithmetic you didn’t have to do steps on both sides of an equation.
Alexa likes watching the show Engineering Marvels.
In last night's episode, the engineering team visited
a tall skyscraper and a deep mine. A banner at the
bottom of the screen showed the elevation of each
location the team visited.
Location Elevation (m)
Top of the skyscraper 275
Bottom of the mine
-260
Which location is closer to sea level?
Answer:
Bottom of the mine
Step-by-step explanation:
I'm assuming sea level is 0, so if it's not I'm wrong. To find the distance, you can't have a negative distance, so if there's a negative or really any number use it's absolute value. Is 260 greater or less than 275? Less than, meaning it's closer to 0.
