Answer:
about 40 cm.
Step-by-step explanation:
I know the length of the third side is 40cm because I used the Pythagorean theorem.
a^2+b^2=c^2 The "a" and "b" values are the lengths of the legs of the triangle, while "c" is the length of the hypotenuse. We know the third side of this triangle is not the hypotenuse.
* The longest side of a right triangle is the hypotenuse, so we know the length of the hypotenuse is 46cm.
Therefore, we plug our values into the Pythagorean theorem.
23^2+b^2=46^2
529+b^2=2116
Next, we subtract 529 on both sides.
b^2=1587
Next, find the square root of 1587, so we can find the true value of b.
b=39.8371685741
Rounded to the nearest centimeter is 40.
In conclusion, the length of the third side is 40cm.

A glass company is repairing a window in the shape of an equilateral triangle. If the length of one side of the triangle is 17 inches and the company charges $12 per square inch, the cost of the replacement window will be $___.
Answer:
the cost of the replacement window will be $1501.44.
Step-by-step explanation:
area of an equilateral triangle:
[tex]A = \frac{\sqrt{3}}{4} a^{2}[/tex]
A = (√3)/4 * (17)^2
A = 125.12 in^2

A weir is a dam that is built across a river to regulate the flow of water. The flow
rate Q (in cubic feet per second) can be calculated using the formula Q = 3.3674h3/2,
where l is the length (in feet) of the bottom of the spillway and h is the depth (in feet)
of the water on the spillway. Determine the flow rate of a weir with a spillway that is
20 feet long and has a water depth of 5 feet. Round your answer to the nearest whole
number
Answer:
752.884 cubic feet
Step-by-step explanation:
Brainliest?
Applying the formula, it is found that the flow rate is of 753 cubic feet per second.
The flow rate is modeled by:
[tex]Q = 3.367lh^{\frac{3}{2}}[/tex]
[tex]Q = 3.367l\sqrt{h^3}[/tex]
In which the parameters are:
l is the length.h is the depth.In this problem:
20 feet long, hence [tex]l = 20[/tex]Depth of 5 feet, hence [tex]h = 5[/tex]Then:
[tex]Q = 3.367l\sqrt{h^3}[/tex]
[tex]Q = 3.367(20)\sqrt{5^3}[/tex]
[tex]Q = 753[/etx]
The rate is of 753 cubic feet per second.

Emmy is tossing bean bags at a target. She hit the target on 9 out of her last 18 tries. Considering this data, how many hits would you expect Emmy to get during her next 16 tosses?
Answer:
I would expect Emmy to get 8 hits in her next 16 tosses.
Emmy is to get 8 hits in her next 16 tosses.
What is probability?Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
Probability = Number of favourable outcomes / Number of samples
Given that Emmy is tossing bean bags at a target. She hit the target on 9 out of her last 18 tries. Considering this data.
The probability is,
P = 9 / 18
P = 0.5
The expected number of the hits on the target in 16 tosses will be;-
Number = 16 x 0.5
Number = 8
Therefore, Emmy is to get 8 hits in her next 16 tosses.

A right cylinder has a radius of 5 and a height of 9. What is its surface area? A. 457 units2 B. 1407 units2 C. 907 units? D. 700 units2
Answer: B
The surface area of the right cylinder is 140π cubic units or 439.60 cubic units.
Step-by-step explanation:
We have formula to find the surface area of a right cylinder.
Surface area = 2πr(h + r)
Given: r = 5 and h = 9,
Now plug in the value of r and h in the above formula, we get
Surface area = 2π.5 (9 + 5)
= 10π(14)
Surface area = 140π
The value of π = 3.14, when we plug in the value of π, we get
The surface area = 140 × 3.14
= 439.60 cubic units.
Therefore, the surface area of the right cylinder is 140π cubic units or 439.60 cubic units.

To measure the distance across a wide river surveyors use a technique of measuring angles to a fixed point on the other side of the river. In the diagram below, a survey starts a point A and find m
Answer:
DC = 1332.95 feet
Step-by-step explanation:
From the figure attached,
Let the measure of DC = h ft
And measure of side BC = a ft
By applying tangent ratio in ΔBCD,
tan(56°) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
= [tex]\frac{DC}{BC}[/tex]
= [tex]\frac{h}{a}[/tex]
h = a[tan(56°)] --------(1)
By applying tangent rule in ΔACD,
tan(22°) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
tan(22°) = [tex]\frac{DC}{BC+AC}[/tex]
= [tex]\frac{h}{a+2400}[/tex]
h = (a + 2400)tan(22°) ------- (2)
Equating the values of h from equations (1) and (2),
a[tan(56°)] = (a + 2400)tan(22°)
a[tan(56°) - tan(22°)] = 2400[tan(22°)]
1.0785a = 968.6629
a = 899.085 ft
From equation (1),
h = 899.085[tan(56°)]
h = 1332.948
h ≈ 1332.95 ft
Ay benefit concert, twelve bands have volunteered to perform but there is only enough time for eight of the bands to play. How many lineups are possible?
The requried, there are 495 possible combination lineups with eight bands out of twelve for the benefit concert.
To determine the number of possible lineups with eight out of twelve bands performing, we need to calculate the combination.
The number of ways to choose eight bands out of twelve without considering the order is given by the combination formula:
[tex]C(n, r) = \dfrac{n!}{ (r! * (n-r)!)}[/tex]
where n is the total number of bands (12 in this case) and r is the number of bands to be chosen (8 in this case).
Let's calculate it:
[tex]C(12, 8) =\dfrac {12!}{(8! * (12-8)!)}[/tex]
[tex]= \dfrac{12!} {(8! * 4!)}[/tex]
= (12 * 11 * 10 * 9) / (4 * 3 * 2 * 1)
= 495
Thus, there are 495 possible combination lineups with eight bands out of twelve for the benefit concert.
