Answer:
27488.92 cm³
Step-by-step explanation:
El volumen de concentre para columna circular = área de superficie del círculo × altura de la columna.
= πr² × h
Dado que:
diámetro = 50 cm
height = d/2 = 50 cm / 2 = 25 cm
= 3.5 cm
Entonces:
El volumen de concentre para columna circular = πr² × h
El volumen de concentre para columna circular = π(25)² × 3.5
El volumen de concentre para columna circular = 6872.23 cm³
Para cuatro columnas circulares; el volumen será: = 4 × 6872.23 cm³
= 27488.92 cm³

Solve the two-step equation. 14=31.7-3x
Answer:
x=5.9
Step-by-step explanation:
First, you want to isolate x so you have to subtract 31.7 from both sides. This will make the equation -3x=-17.7. Because they are both sides are negative, you can change both sides to positive so it will be 3x=17.7. Next, you want x to be 1 so you have to divide 3 in both sides. This will make the equation x=17.7/3. Simplify that to get x=5.9.

If the ratio of boys to girls in the school band is 2 to 3, which of these show possible numbers
of the boys and girls in band.
A. 24 boys, 36 girls
B. 20 boys, 35 girls
C. 36 boys, 24 girls
D. 35 boys, 20 girls
Answer:
A
Step-by-step explanation:
Simply guess and check, meaning the boys category must be divisible by 2 and the girls category must be divisible by 3
A: 24 boys ÷ 2 = 12 (equals a whole number so it is divisible; not a decimal)
36 girls ÷ 3 = 12 (both of the boys and girls are divisible by their corresponding numbers)
Yes
Now make sure the boys are a lower count than the girls as the ratio says it should be 2 to 3, meaning there are more girls than boys
B: 20 ÷ 2 = 10 (divisible)
35 ÷ 3 = 11.666 (this is a decimal answer so it is not divisible)
No
C: 36 ÷ 2 = 18
24 ÷ 3 = 8
Yes, they are divisible
Now lets check if boys have a lower count than girls
36 boys > 24 girls
This is not the solution as it doesn't reflect the correct ratio of less boys than girls
D: 35 ÷ 2 = 17.5 (not divisible)
20 ÷ 3 = 6.66 (not divisible)
Easy but not for me. Help needed

circumference = 110 x π
circumference = 345.58 ft
2x+y=40 kx+2y=80
A system of equations is shown, where k is a constant. If the lines represented by the equations in the system are graphed in the xy-plane, for what value of k would the lines coincide?
A. -4
B. 1
C. 2
D. -4
The value of 'k' for the given system of equation that coincides is 4
k=4
Given :
System of equations
[tex]2x+y=40 \\kx+2y=80[/tex]
The given equation is in the form of ax+by=c
When the two lines coincides then
[tex]\frac{a_1}{a_2} =\frac{b_1}{b_2} =\frac{c_1}{c_2}[/tex]
Lets make the coefficients proportional to each other and then solve for k

What conclusion can be drawn from the quiz scores shown below?
Ken's class: 72, 78, 83, 84, 85, 87, 92
Judy's class: 76, 78, 85, 87, 89, 92, 98
Answer:
Ken class has a median of 84 while Judy class a median of 87
Step-by-step explanation:
Ken class has a median of 84 while Judy class a median of 87
Kens class has a mean score of 83, and Judy's class has a mean score of 86.43(rounded) so, judging by the mean, Judy's class is smarter. If we take a look at the median, (Ken: 84, and Judy: 87) then Judy's class is smarter. So, overall Judy's class is smarter than Ken's class.

Answer:
a) 21 √m inches
b) 13√2/2 m
Step-by-step explanation:
a) we want to find the perimeter of an equilateral triangle
An equilateral triangle is one which sides has the same equal length
The perimeter of this triangle is the sum of the lengths of the three sides
Mathematically, we have this as:
7 √m + 7 √m + 7 √m
= 21 √m inches
b) we want to calculate the perimeter of the given rectangle
Mathematically, we can calculate the perimeter of a rectangle using the formula below;
P = 2(l + b)
where l represents the length of the rectangle and b represents the breadth of the rectangle
From the given shape;
l = √50 m, b = 1/2 √32
So, we have the perimeter follows;
2( √32/2 + √50)
= √32 + √50/2
√32 = 4√2
√50 = 5√2
Thus, we have;
4 √2 + 5 √2/2
= (8 √2 + 5 √2)/2 = 13√2/2

A ladder that is 13 feet long leans against a building .The bottom of the ladder is 5 feeet away from the base of the building .how far up the side of the building does the ladder reach?
Length of the ladder = 13 m
Foot of the ladder from the wall = 5 m.
The upper end of the ladder is (13^2–5^2)^0.5 = 12 m above the ground.
In 1 second the foot of the ladder is 7 m from the wall, while the top end is (13^2–7^2)^0.5 = (169–49)^0.5 = 120^0.5 = 10.95 m. Then the top moves 1.05 m downwards.
In 2 seconds, the foot of the ladder is 9 m from the wall, while the top end is (13^2–9^2)^0.5 = (169–81)^0.5 = 88^0.5 = 9.38 m. Then the top moves 3.62 m downwards.
In 3 seconds, the foot of the ladder is 11 m from the wall, while the top end is (13^2–11^2)^0.5 = (169–121)^0.5 = 48^0.5 or 6.93 m. Then the top moves 6.07 m downwards.
So, if the foot of the ladder moves at a constant rate of 2 m/s the top end of the ladder moves downwards which varies from second to second.Answer: The lader will form the hypotenuse. Length of hypotenuse = 13m.
Let us take the horizontal distance between the wall and the ladder as ‘ground’. This g = 5m
wall ^ 2 + ground ^ 2 = 13^2 = 169
w^2 + g^2 = 169
w^2 + 25 = 169. Thus, w^2 = 144. Thus, w = 12
Rate of change of ground distance = dg / dt = 2m/s (given).
In the equation w^2 + g^2 = 169, differentiate the equation with respect to time.
2 w dw/dt + 2 g dg/dt = 0
2 (12) (dw/dt) + 2 (5) (2) = 0. So, 24 dw/dt + 20 = 0
dw/dt = -20 / 24 = -5 / 6
Thus, the height of the wall is decreasing at a rate of -5/6 m / s (that is, -0.833m/s)
The minus sign denotes that the height of the ladder is falling.

the answer to the question above and it’s not 75
Answer:
The 2 triangles on the right and left are isosceles, so they have 2 equal sides. Consequently, the angles at the base are equal.
Because the opposite angles of a vertix are equal, the triangle in the lower part has the angles x, 58° and 47°.
Because the sum of the inner angles of a triangle is 180, x= 180- (58+47)
x= 180-105 = 75°
Pls mark as brainliest
Answer: x = 72
Step-by-step explanation:
The triangle with ∠a is an isosceles triangle; the other two angles are congruent, let them be y
a + y + y = 180 (sum of angles in triangles)
58 + 2y = 180
Subtract 58 from both sides
2y = 122
Divide both sides by 2
y = 61°
In the triangle with ∠b, b is congruent to another angle, (isosceles triangle) let it be b.
b = 47°
y and b have a relationship with the other two of the angles with ∠x (vertical angles); let them be y and b.
y + b + x = 180
61 + 47 + x = 180
108 + x = 180
Subtract both sides by 108
x = 72
Tanisha and Bess are sisters. Tanisha is half as old as Bess. Bess is 6 years older than Tanisha.
How old is each sister?
A. Tanisha is 3, and Bess is 6.
B. Tanisha is 3, and Bess is 9.
c. Tanisha is 6, and Bess is 9.
D. Tanisha is 6, and Bess is 12.
Answer: a
Step-by-step explanation: because bess it says she has 6 and is 3 it says have of 6 is 3 so it is 3
The age of Tanisha is 6 years and the age of Bess is 12 years. Therefore, option D is the correct answer.
We need to find the age of Tanisha and Bess.
What is an equation?A statement that the values of two mathematical expressions are equal (indicated by the sign =).
Let the age of Tanisha be x.
Bess is 6 years older than Tanisha.
Now, Bess=x+6
Tanisha is half as old as Bess.
Now, Tanisha=1/2×Bess
⇒x=1/2×(x+6)
⇒x=6
So, Tanisha's age=6 years and Bess's age=12 years.
