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.

Answer:
Length is 138 ft, area is 412 ft
Step-by-step explanation:
The length is determined by the perimeter, so add both side of the perimeter together, and you have your length. Area is determined by perimeter + Length, to add both sides of perimeter and length and you get 412 ft.

Triangle Sums***GRADED 1 of 51 of 5 Items #1 Triangle RST is shown. What is the measure of ∠T? Record your answer and fill in the bubbles on the grid. Be sure to use correct place value.
Answer:
[tex]\angle T = 70[/tex]
Step-by-step explanation:
Given
[tex]\angle T= 2x[/tex]
[tex]\angle S= 75[/tex]
[tex]\angle R= x[/tex]
See attachment for triangle
Required
Calculate [tex]\angle T[/tex]
First, we add up the angles in the triangle;
[tex]\angle R + \angle S + \angle T = 180[/tex]
[tex]x + 75 + 2x = 180[/tex]
Collect like terms
[tex]x + 2x = 180 - 75[/tex]
[tex]3x = 105[/tex]
Solve for x
[tex]x = \frac{105}{3}[/tex]
[tex]x = 35[/tex]
Given that:
[tex]\angle T= 2x[/tex]
[tex]\angle T = 2 * 35[/tex]
[tex]\angle T = 70[/tex]
The cost of a banquet at Nick's Catering is $215 plus $27.50 per person. If
the total cost of a banquet was $2827.50, how many people were invited?
Answer:
x = 95
Step-by-step explanation:
Given that,
The cost of a banquet at Nick's Catering is $215 plus $27.50 per person
The total cost of a banquet was $2827.50
We need to find the number of people invited. Let there are x people. So,
215+27.5x = 2827.50
27.5x = 2827.50 -215
27.5x = 2612.5
x = 95
So, there are 95 people that were invited.

In the figure below, m LMK = 26° and m KLM = 33° What is m MKJ? A. 52° B. 66° C. 59° D. 121°
Answer:
option c
Step-by-step explanation:
first use angle sum property, then use
linear pair axiom
Answer:
D: 121
Step-by-step explanation:
Step One: To do this problem, you must understand the rule that all angles in a triangle add up to 180 degrees.
Step Two: Now that we know the rule, we know this triangle equals 180 degrees. First, we must add the angles we DO know together: 26+33= 59.
Step Three: We can subtract 59 from 180 to find the missing angle: 180-59= 121.

Un paseo tiene una longitud de 1250 km. Se quiere plantar un árbol cada 0,025 km. ¿cuantos arboles se plantaran? ¿ y si se planta un arbol cada 50 m?
Answer:
-Se plantarán 50.000 arboles.
-Si se planta un árbol cada 50 m, se plantarán 25.000 arboles.
Step-by-step explanation:
Para encontrar cuántos arboles se plantarán, tienes que dividir la longitud el paseo entre la distancia que habrá entre los árboles:
1250/0,025=50.000
Ahora, para encontrar cuántos arboles se plantarán si se planta uno cada 50m, primero tienes que encontrar cuántos kilómetros hay en 50 m considerando que 1 km es igual a 1000 metros. Para esto, puedes utilizar una regla de tres:
1 km → 1000 m
x ← 50 m
x=(50*1)/1000
x= 0,05 km
Ahora puedes dividir la longitud del paseo entre 0,05 para encontrar el número de arboles que se plantarán:
1250/0.05=25.000
De acuerdo a esto, la respuesta es que se plantarán 50.000 arboles.
Si se planta un árbol cada 50 m, se plantarán 25.000 arboles.

Step-by-step explanation:
The volume of the rectangular pyramid is calculated as
V = [tex]\frac{1}{3}[/tex] Ah ( A is the area of the base and h the perpendicular height )
Here A = 10 × 6 = 60 ft² and h = 6 , then
V = [tex]\frac{1}{3}[/tex] × 60 × 6 = 20 × 6 = 120 ft³
The volume of the rectangular prism is calculated as
V = 10 × 6 × 4 = 60 × 4 = 240 ft³
Total volume = 120 + 240 = 360 ft³

B. x + 47 = 180 The unknown angles are both 133 degrees
C. x + 7 + 2x - 40 = 90 One angle is 48 degrees and the other is 42 degrees
D. x + 7 = 2x - 40 The unknown angles are both 54 degrees
Answer:
Answer:
To determine to measure of the unknown angle, be sure to use the total sum of 180°. If two angles are given, add them together and then subtract from 180°. If two angles are the same and unknown, subtract the known angle from 180° and then divide by 2.
