what is the value of x in the diagram below?
Answer:
C
Step-by-step explanation:
using the Altitude- on- Hypotenuse theorem
(leg of big Δ )² = (part of hypotenuse below it ) × ( whole hypotenuse )
x² = 20 × (20 + 36) = 20 × 56 = 1120 ( take square root of both sides )
x = [tex]\sqrt{1120}[/tex] = [tex]\sqrt{16(70)}[/tex] = [tex]\sqrt{16}[/tex] × [tex]\sqrt{70}[/tex] = 4[tex]\sqrt{70}[/tex]

hello people ~
The length of a rectangular screen is 15 cm. Its area is 180 sq. cm. Find its width.
Answer:
W=12 cm.
Step-by-step explanation:
If the total area is 180 sq. cm., and you multiply length times width to find area, this time it is inversed. So you do 180/15=12
Answer:
12 cm
Step-by-step explanation:
The area of a rectangle = length × width
We know that the length is 15 cm and the area is 180 cm² so we can substitute this into the equation:
180 cm² = 15 cm × width
Finally, we can divide both sides by 15 to find the width:
width = 180 ÷ 15
width = 12 cm

We can see that using the vertical line test, none of the x points cross the line more than once, that means that it is a function, since it passes the vertical line test.
Reflect triangle A in the line y=1
Answer:
To reflect the shape in the line y = 1:
The x-coordinates will stay the same.The y-coordinate = 1 - (y-value - 1)(-4, 4) → (-4, -2)
(-1, 4) → (-1, -2)
(-1, 2) → (-1, 0)

so, the figure is really one big square, a 10x10, with four triangles in it, now, if we just get the area of the square, well 10x10 is just 100 in², and then get the areas of those three triangles, the yellow, purple and orange ones, and subtract their area from that of the larger square, what's leftover is the shaded triangle. By subtracting the areas from the larger area, we're in essence making a big hole in the larger area, and what's leftover is what was never subtracted.

1.) Daniel stands on one side of a stream that is 400 feet wide. He wants to reach his campsite that is 1600 feet downstream on the opposite side. He decides he will swim to the boat ramp on the opposite side, which is part way downstream toward the campsite, then jog the rest of the way. The angle formed by Daniel’s swim path and the shore at the boat ramp is.
Draw a labeled diagram of the scenario.
Answer: ?
2.) Daniel can swim at an average rate of 150 feet per minute. How many minutes does it take him to swim to the boat ramp? Round your answer to the nearest hundredth.
Answer: ?
3.) How far is the boat ramp from the campsite? Round your answer to the nearest hundredth.
Answer: ?
4.) Daniel can jog at 4 miles per hour. How many minutes does it take him to jog from the boat ramp to the campsite? Round your answer to the nearest hundredth.
Answer: ?
5.) Daniel arrives at his campsite out of breath from his swim and jog. His sister tells him that he should have swam to the boat ramp that is only 200 feet from the campsite and then jogged. She claims that he would have arrived quicker this way.
Is Daniel’s sister correct? Support your answer mathematically.
Answer: ?
(Please please do not answer if you aren't 100% sure of the answer!!)
From Daniel's initial location from the campsite given the width of the
stream is 400 feet and Daniel swims to the boat ramp, we have;
1.) Please find attached the drawing of the situation
2.) 3.34 minutes
3.) 1,298.59 feet
4.) 3.69 minutes
How can the distances and times be calculated?1.) Please find attached a labelled diagram of the scenario created with MS Visio
2.) Daniel's average swimming rate (speed) = 150 feet per minute
[tex]The \ distance \ Daniel \ swims = \mathbf{\dfrac{400 \, feet}{sin(53^{\circ})}} \approx 500.85 \, feet[/tex]
The time it takes him to swim to the boat ramp, t, is therefore;
[tex]t \approx \dfrac{500.85 \ feet}{150 \ feet/min} \approx \underline{3.34 \ minutes}[/tex]3.) The distance, d₁, downstream of the boat ramp from Daniel is given as follows;
d₁ = √((500.85 feet)² - (400 feet)²) ≈ 301.41 feet
Therefore;
The distance from the boat ramp to the campsite, d₂, is therefore;
d₂ ≈ 1600 feet - 301.41 feet = 1,298.59 feet
The distance from the boat ramp to the campsite, d₂ ≈ 1,298.59 feet
4. The time, t₂, it will take Daniel to jog from the boat ramp to the campsite is given as follows;
[tex]t_2 = \mathbf{\dfrac{d_2}{v_2}}[/tex]
Where;
v₂ = The rate at which Daniel can jog, which is 4 mph
Which gives;
[tex]t_2 = \mathbf{\dfrac{1298.59 \, feet}{4 \, mph}} = \dfrac{1298.59 \, feet}{4 \, mph} \approx \dfrac{1298.59 \, feet}{5.866142 \ feet/s} \approx \dfrac{221.37 \, s}{60 \, s/min} \approx 3.69 \, min[/tex]
Therefore;
The time it takes him to jog from the boat camp to the campsite, t₂ ≈ 3.69 minutesLearn more about Pythagorean theorem here:

a rectangular prism is 18 inches long 6 1/2 inches wide and has a volume of 292 1/2 cubic inches. which equation can u use to find the height
The equation that represent the height of the rectangular prism is h = v / lw, where the value of height is 2.5 inches
Volume of a rectangular prismv = lwhwhere
l = length
w = width
h = height
Therefore,
l = 18 inches
w = 6 1 / 2 = 13 / 2 inches
h =?
v = 292 1 / 2 = 585 / 2
Therefore,
h = v / lw
h = 585 / 2 × 1 / 18 × 2 / 13
h = 585 / 234
h = 2.5 inches
