The height of an electricity tower is 200 ft. tall. The tower is secured by a wire, stretching from the top of the tower to a spot on the ground 50 ft. away from the base of the tower. The wire creates a right triangle with the tower and the ground. What is the length of the wire to the nearest foot?
*Please explain your answer and how you got it.*
***ONLY ANSWER IF YOU KNOW*** DON'T SAY I'M WORKING ON IT
Answers
Answer:
Let AB be the height of electric tower and BC be its base.
it forms a right angled triangle
so
base=BC=50ft
hypotenuse =AC=?
perpendicular=AB=200ft
by using Pythagoras law
h²=p²+b²
AC²=200²+50²
AC=√42500
AC=206.15ft
206.15ft is the length of wire.

The ten expressions that requires BEMAS solution are: + 3 x 2 - 5 ÷ 1
2 x 3 + 8 ÷ 4 - 110 ÷ 2 + 5 - 3 x 27 - 4 x 3 + 2 ÷ 15 x 2 + 4 - 6 ÷ 33 ÷ 1 + 4 x 2 - 76 - 2 ÷ 1 + 5 x 39 + 1 x 2 - 4 ÷ 212 ÷ 3 - 1 x 5 + 28 - 6 ÷ 2 + 3 x 1What are the solutions of the expression?
Now, let's solve each of these expressions using the BEDMAS rule:
(1) 4 + 3 x 2 - 5 ÷ 1 = 4 + 6 - 5 = 5
(2) 2 x 3 + 8 ÷ 4 - 1 = 6 + 2 - 1 = 7
(3) 10 ÷ 2 + 5 - 3 x 2 = 5 + 5 - 6 = 4
(4) 7 - 4 x 3 + 2 ÷ 1 = 7 - 12 + 2 = -3
(5) 5 x 2 + 4 - 6 ÷ 3 = 10 + 4 - 2 = 12
(6) 3 ÷ 1 + 4 x 2 - 7 = 3 + 8 - 7 = 4
(7) 6 - 2 ÷ 1 + 5 x 3 = 6 - 2 + 15 = 19
(8) 9 + 1 x 2 - 4 ÷ 2 = 9 + 2 - 2 = 9
(9) 12 ÷ 3 - 1 x 5 + 2 = 4 - 5 + 2 = 1
(10) 8 - 6 ÷ 2 + 3 x 1 = 8 - 3 + 3 = 8

On a particularly windy day, the percentage of target hits for different distances from the target were recorded for several participants at a children's archery camp. The data is shown in the scatter plot below.
The equation for the line of best fit is as shown below.
Y = 90 - 2.75x
Use the equation for line of best fit to interpret the slope and y-intercept. Based on the line of best fit, predict the percentage of target hits from a distance of 32 meters?
Answers
y= 90- 2.75(32)
y= 90- 88
y= 2
And since y is a percentage, your answer will be
2% of target hits from a distance of 32 meters.

Find the surface area of a top open cylinder
12 in radius
2 in height
Answers
The surface area of the top open cylinder is 6810.149 sq.cm.
A cylinder is a three-dimensional solid that consists of two congruent surfaces (bases) and one lateral surface.
Surface area of a cylinder = Base area + Lateral area
Base area of a cylinder = 2 × π × r²
Lateral area of a cylinder = (2 × π × r) × h
Therefore, here base area of a cylinder = 2× π × 12²
= 5837.27 sq.cm.
And, lateral area of a cylinder = (2 × π × 12) × 2
= 972.8784 sq.cm.
Therefore, total surface area of a cylinder = 5837.27 + 972.8784
= 6810.149 sq.cm.

In the given figure angle CBF and angle CEF are supplementary angles. So Option C is correct.
What is an angle ?
An angle is a mathematical term, which we can define, when two straight lines or rays meet at a common endpoint. The common point is called the vertex of an angle. The word angle comes from a Latin word named ‘angulus,’.
Given that,
A figure which contains one trapezium BCEF
And in this portion angle CBF and angle BCE are opposite angles
and opposite angles are supplementary angles,
Hence, the pairs of angles are ∠CBF & ∠CEF
