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?
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
4. This is a
function
5. The equation is
6. The value for f(-4) is
THREE NUMBERS BEHIND THE DECIMAL PT
Answer:
Step-by-step explanation:
4). This is an exponential function.
5). Let the equation of this function is,
f(x) = a(b)ˣ
Since, two points (-1, 4) and (0, 6) are lying on the graph of the function,
For (-1, 4),
4 = a(b)⁻¹
4 = [tex]\frac{a}{b}[/tex] --------(1)
For (0, 6),
6 = a(b)⁰
a = 6
From equation (1),
4 = [tex]\frac{6}{b}[/tex]
b = [tex]\frac{6}{4}[/tex] = 1.5
Therefore, equation of the function will be,
f(x) = 6(1.5)ˣ
6). Now the value of f(-4) will be,
f(-4) = 6(1.5)⁻⁴
= 1.185

If x + y = 12 and x = 2y, then x=
The value of x is equal to 8.
Given the following equation;
[tex]x + y = 12[/tex] .....equation 1
[tex]x = 2y[/tex] .....equation 2
To find the value of x, we would solve the system of equations by using the substitution method to determine the value of y;
Substituting eqn 2 into eqn 1, we have;
[tex]2y + y = 12[/tex]
[tex]3y = 12\\\\y = \frac{12}{3}[/tex]
y = 4
Next, we would solve for the value of x;
From equation 2;
[tex]x = 2y\\\\x = 2(4)[/tex]
x = 8
Therefore, the value of x is equal to 8.

Yolanda made $242 for 11 hours of work. At the same rate, how many hours did she have to work to make $198.
His hourly rate is:
242/11=22 dollars
( dollars/hour ) x ( hours worked ) = dollars earned
Let t= hours worked
22t+=198
t=198/22
t=9
Yolanda needs to work 9 hrs
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
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
Mars has m moons. The number of moons of Pluto is one more than twice the number of moons of Mars. The number of moons of Neptune is one less than 3 times the number of moons of Pluto. Write and interpret a simplified expression that represents the number of moons of Neptune (I’m just asking to answer because I didn’t see any right ones when I was scrolling through them)
Answer:
neptune = 6m+2
Step-by-step explanation:
mars has 'm' moons
pluto has one more than twice that of mars, = 2m+1
neptune is one less than thrice of pluto
= 3(2m+1) -1
= 6m+3 -1
= 6m+2

Write a second equation whose graph goes through (0,1) so the system has no solutions.
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

3. If the average of 16, 14, x, 23, 20 is 18, find the value of x.
LA
Maths
Answer:
x = 17
Step-by-step explanation:
Here, we want to find the value of x
mathematically, the mean is the sum of the numbers divided by the count of the numbers
The count of the numbers is 5
So we have;
(16 + 14 + x + 23 + 20)/5 = 18
73 + x = 5(18)
73 + x = 90
x = 90-73
x = 17

the cost of 7 toys is AED 294. the cost of 5 toys. (Unitary method)
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

Adult movie tickets cost $8 each. Children pay $5 for a ticket. For one movie, 90 total tickets were sold for a total of $525. Which system of equations can be used to find the number of each type of ticket, adult, a, and children, c, that were sold?
A. a + c = 90 8a + 5c = 525
B. a + c = 525 8a + 5c = 90
C. a + c = 90 5a + 8C = 525
D. a + c = 525 5a + 8C = 90
Answer: A
Step-by-step explanation:
I had this question on my test yesterday lol
The system of equation will be ". a + c = 90 8a + 5c = 525"
Let the number of adults tickets be represented by a
Let the number of children tickets be represented by c.
Since 90 total tickets were sold, this can be represented by the equation:
a + c = 90
Since adult movie tickets cost $8 each while the children pay $5 for a ticket, and total cost spent is $525, this will be:
8a + 5c = 525
Therefore, the correct option is A.

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.
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
