The angle of elevation from a kicker's foot on the football field to the top of the goal post is 17 degrees. If he is standing 131 feet from the base of the goal post, how tall is the goal post?
Answers
Answer:
The goal post is 40.05 feet tall.
Step-by-step explanation:First, you need to decide whether to use sin, tan or cos.
You have the angle, the adjacent and need the opposite , so you need to find out which one has all three values in
Sin
Cos
Tan
So you need to use tan.
Tan = opposite / adjacent, so rearrange the formula to make opposite the subject:
[tex]Opp = Tan * adj
So simply plug these values in:
[tex]Opp =131 * tan(17) = 40.05
So the goal post is 40.05 feet tall

Write a second equation whose graph goes through (0,1) so the system has no solutions.
Answers
Answer:
y = 5x + 1
Step-by-step explanation:
Hello There!
Equations that have no solutions are parallel
So the line we are going to create an equation for has the same slope as the line drawn
To find the slope we do change in y divided by change in x
as y goes 5 x goes up 1
so the slope is 5/1 or 5
The requirements for the equation is it has to go through the points (0,1)
The ordered pair listed is the y intercept so the equation would be
y = 5x + 1

Sam and Ella were running in a race. Sam ran ⅞ of a mile and Ella ran 5/10 of a mile. At the end of the race they wanted to compare how far they ran. Ella said they could compare the fractions by comparing each fraction to ½. Show how Ella could compare 5/10 and ⅞ to ½ . Then explain who ran further and how you know.
Answers
Answer:
ELLA
Step-by-step explanation:
Given that :
Distance covered by Ella = 5/10
Distance covered by Sam = 7/8
Comparing each distance to 1/2
Ella = 5/ 10 = 1/2 ; 1/2 = 1/2 = 0.5
Sam = 7/8 = 0.875 ; comparing with 1/2
0.875 > 0.5
Given
Sam ran farther Than ELLA
Because 0.875 > 1/2
0.875 - 0. 5 = 0.375
What is the slope of the equation: y = - 5x -6
What is the y-intercept of the equation: y = 2x
Answers
Answer:
Step-by-step explanation:
y = mx +b
Here, m is slope and b is y-intercept
1) y = -5x - 6
Slope = -5
y-intercept = -6
2) y = 2x
Slope = 2
y-intercept = 0

a flomming tile has the shape of a parallelogram whose base is 24cm and height is 10 cm how many tiles are required to cove the floor of area 1080m2
Answers
Answer:
4 1/2 tiles are needed to cover this area
Step-by-step explanation:
Mathematically, the area of a parallelogram is the product of the base and the height
We have this as;
24 * 10 = 240 cm^2
So the area of a tile is this
The number of tiles that will cover the given area will be;
1080/240 = 4.5 tiles

the cost of 7 toys is AED 294. the cost of 5 toys. (Unitary method)
Answers
Answer:
AED 210
Step-by-step explanation:
If the cost of 7 toys is AED 294, this is written as;
7 toys = AED 294
To get the cost of 5 toys, this is written as;
5 toys = x
Divide both expressions
7/5 = 294/x
Cross multiply
7x = 5 * 294
7x = 1470
x = 1470/7
x = 210
Hence the cost of 5 toys is AED 210
