A flagpole, 12 m high, is supported by three wires attached from the top of the pole to the ground. Each wire is pegged into the ground 5 m from the pole. How much wires needed to supported the pole?
Step-by-step explanation:
base=5m
height=12
Pythagoras formula A2+b²=c2
so 12²+5²
144+25=169
so
√169=13m
Answer: 3 wires of 13 m =39m
Base side = 5m
Vertical side = 12m
Hypotenuse = length of one wire.
5^2 + 12^2 = Hypotenuse^2
Hypotenuse = 13m
3 wires of 13m length = 39m
What is the area of the trapezoid? A trapezoid has a base of 12 centimeters, a height of 16 centimeters, and a top side length of 10 centimeters. 176 cm2 192 cm2 208 cm2 224 cm2
Answer:
176
Step-by-step explanation:
option a ( 176 cm²)
A trapezoid has a base of 12 centimeters, a height of 16 centimeters, and a top side length of 10 centimeters.
To find the area, we use the formula for the area of a trapezoid:
Area = 1/2 × (Base1 + Base2) × Height
Here, Base1 is 12 cm,
Base2 is 10 cm, and
the height is 16 cm.
the sum of the bases:
12 cm + 10 cm
= 22 cm.
Multiply by the height:
22 cm × 16 cm
= 352 cm².
Divide by 2 to get the area:
352 cm² ÷ 2
= 176 cm².
So, the area of the trapezoid is 176 cm².
| 57. Macy, Sydney, and Alle are sisters. Macy is liyo
years older than Sydney and Allie is one war
less than half the age of Sydney. If the sum of
their ages is 31, how old is Magy?
Let S be Sydney's age.
Macy = S + Liyo, Alle = (1/2)S - 1.
Given, S + (S + Liyo) + ((1/2)S - 1) = 31.
Substituting Liyo = S and solving gives Sydney = 10, Macy = 15.
So, Macy is 15 years old.
To solve this problem, let's assign variables to represent each sister's age. Let S be Sydney's age. Given that Macy is Liyo years older than Sydney, Macy's age would be S + Liyo. Since Allie is one year less than half the age of Sydney, Allie's age can be represented as (1/2)S - 1.
The sum of their ages is given as 31, so we can set up the equation: S + (S + Liyo) + ((1/2)S - 1) = 31. Substituting Liyo with S, we can solve for Sydney's age (S). Once we find Sydney's age, we can then find Macy's age by adding Liyo to Sydney's age.
By solving the equation, we find that Sydney is 10 years old. Thus, Macy is 15 years old (10 + Liyo). Therefore, Macy is 15 years old.
Complete Question:
Macy, Sydney, and Alle are sisters. Macy is liyo years older than Sydney and Allie is one war less than half the age of Sydney. If the sum of their ages is 31, how old is Magy?

If f(x) = x2 − 6x + 19, complete the square and determine the minimum or maximum value of the function
Answer:
minimum value = 10
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
To obtain this form using completing the square
add/subtract ( half the coefficient of the x- term )² to x² - 6x
f(x) = x² + 2(- 3)x + 9 - 9 + 19
= (x - 3)² + 10 ← in vertex form
with (h, k) = (3, 10 )
To determine maximum or minimum consider the value of a
• If a > 0 then minimum value of k
• If a < 0 then maximum value of k
Here a = 1 > 0, hence minimum value of k = 10
The Carousel in the National Mall has 4 rings of horses. Kelly is riding on the inner ring, which has a radius of 9 feet.

Maya travels [tex]4.19 feet/sec[/tex] faster than Kelly !
Difference in distance is : [tex]106.76-56.52 = 50.24 feet[/tex]
Step-by-step explanation:
Here we have , The Carousel in the National Mall has 4 rings of horses. Kelly is riding on the inner ring, which has a radius of 9 feet. Maya is riding on the outer ring, which is 8 feet farther out from the center than the inner ring is. We need to find In one rotation of the carousel, how much farther does Maya travel than Kelly . Let's find out:
Kelly is riding on the inner ring, which has a radius of 9 feet
Total distance traveled by Kelly is circumference of circle with radius 9 feet i.e.
⇒ [tex]Distance = 2\pi r[/tex]
⇒ [tex]Distance = 2(3.14) 9[/tex]
⇒ [tex]Distance = 56.52feet[/tex]
Maya is riding on the outer ring, which is 8 feet farther out from the center than the inner ring .
Total distance traveled by Maya is circumference of circle with radius (8+9=17) feet i.e.
⇒ [tex]Distance = 2\pi r[/tex]
⇒ [tex]Distance = 2(3.14) 17[/tex]
⇒ [tex]Distance = 106.76feet[/tex]
Therefore , Difference in distance is : [tex]106.76-56.52 = 50.24 feet[/tex]
Now , Speed of both is give by
⇒ [tex]Speed_k_e_l_l_y=\frac{56.52}{12} = 4.71 feet/sec[/tex] And ,
⇒ [tex]Speed_M_a_y_a=\frac{106.76}{12} = 8.90 feet/sec[/tex]
Faster Maya travels = 8.90-4.71 = 4.19

-7 = -1 + [tex]\frac{x}{3}[/tex]
To solve this you must isolate x.
On the right side of the equation the one is negative. To cancel the -1 from the right side you must add 1 to both sides (what you do to one side you do to the other) since addition is the opposite of subtraction (negative). Doing this will make -1 zero on the right side of the equation and bring it over to the left side
-7 + 1 = -1 + 1 + [tex]\frac{x}{3}[/tex]
-6 = 0 + [tex]\frac{x}{3}[/tex]
-6 = [tex]\frac{x}{3}[/tex]
The x is being divided by 3 and the opposite of division is multiplication. To completely isolate x you must multiply 3 to both sides. This will cancel the three out on the right side of the equation and bring it over the left side.
-6 * 3 = [tex]\frac{x}{3}[/tex] * 3
-18 = x
Now check:
-7 = -1 + [tex]\frac{-18}{3}[/tex]
-7 = -1 + (-6)
-7 = -7
^^^This is true which means that x = -18

Martin is going to ride in the great bicycle race which is 7/10 as long as the 100- mile astounding race how long is the great bicycle race
Answer: 70 miles long
Step-by-step explanation:
7/10 x 100 = 70
its 70 miles long
Final answer:
The great bicycle race is 70 miles long.
Explanation:
To find the length of the great bicycle race, we need to multiply the length of the 100-mile astounding race by 7/10. Since 7/10 is a fraction, we can represent it as 7 divided by 10. Multiplying by a fraction is the same as multiplying the numerator by the same factor as the denominator. Therefore, we can multiply 100 by 7 and divide by 10 to find the length of the great bicycle race.
There are a few ways to do this computation. One way is to multiply 100 by 7, which equals 700, and then divide 700 by 10. The result is 70 miles. Therefore, the great bicycle race is 70 miles long.

The height of the cylinder is 4x units.
Answer:
The radius of the cylinder is (1/2)x units
The area of the cylinder’s base is (1/4)πx2 square units
The height of the cylinder is 4x units
Step-by-step explanation:
The complete question is
A cylinder with a base diameter of x units has a volume of πx3 cubic units.
Which statements about the cylinder are true? Check all that apply.
(1) The radius of the cylinder is (1/2)x units.
(2) The radius of the cylinder is 2x units.
(3) The area of the cylinder’s base is (1/4)πx2 square units.
(4) The area of the cylinder’s base is (1/2)πx2 square units.
(5) The height of the cylinder is 2x units.
(6) The height of the cylinder is 4x units
we know that
The volume of the cylinder is equal to
[tex]V=\pi r^{2}h[/tex]
we have
[tex]r=\frac{x}{2}\ units[/tex] ----> the radius is half the diameter
[tex]V=\pi x^{3}\ units^3[/tex]
substitute the given values in the formula of volume
[tex]\pi x^3=\pi (\frac{x}{2})^{2}h[/tex]
solve for h
simplify
[tex]x=(\frac{1}{4})h[/tex]
[tex]h=4x\ units[/tex]
Verify each statement
(1) The radius of the cylinder is (1/2)x units
The statement is true
see the explanation
(2) The radius of the cylinder is 2x units.
The statement is false
Because, the radius of the cylinder is x/2 units
(3) The area of the cylinder’s base is (1/4)πx2 square units
The statement is true
Because, the area of the cylinder's base is equal to
[tex]A=\pi r^{2}[/tex]
[tex]r=\frac{x}{2}\ units[/tex]
substitute
[tex]A=\pi (\frac{x}{2})^{2}[/tex]
[tex]A=\frac{\pi x^2}{4}\ units^2[/tex]
(4) The area of the cylinder’s base is (1/2)πx2 square units.
The statement is false
Because, the area of the cylinder's base is equal to
[tex]A=\frac{\pi x^2}{4}\ units^2[/tex]
see the part (3)
(5) The height of the cylinder is 2x units.
The statement is false
Because, the height of the cylinder is 4x units (see the explanation)
(6) The height of the cylinder is 4x units
The statement is true
see the explanation

What does the value of x have to be so that
(x,-7) and (-1,4) have a slope of 11/4 between them?
Solution:
The slope of a line is given by formula:
[tex]Slope = \frac{ y_2-y_1}{x_2-x_1}[/tex]
From given,
[tex]slope = \frac{11}4}\\\\(x_1, y_1) = (x, -7)\\\\(x_2, y_2) = (-1, 4)[/tex]
Substituting the values we get,
[tex]\frac{11}{4} = \frac{4+7}{-1-x}\\\\-11 - 11x = 11 \times 4\\\\-11-11x = 44\\\\11x = -11-44\\\\11x = 55\\\\x = 5[/tex]
Thus the value of x is 5
