5. A student wants to know how tall the flagpole at her school is, her eye level is 5.5 feet above
the ground and she stands 36 feet from the base of the flagpole. If the angle of elevation is
25°, what is the height of the flagpole?
Answer:
22.3 ft
Step-by-step explanation:
Here we can make a triangle rectangle with the following vertex:
The student's eye level.
The top of the flagpole
The intersection between a horizontal line that passes through her eye level and a point in the flagpole.
The catheti of this triangle rectangle will be:
The distance between her and the flagpole (36ft)
The height of the flagpole minus the height of her eye level = H
We want to find the value of H.
We also know that the angle of elevation from her point of view is 25°.
(for this angle, the adjacent cathetus is the distance between her and the flagpole)
Now we can remember the relation:
Tan(a) = opposite cathetus/adjacent cathetus.
Then:
Tan(25°) = H/36ft
Solving for H we get:
Tan(25°)*36ft = H = 16.8 ft
And this is the height of the flag pole minus the height of her eye level, then the actual height of the flagpole is:
H + 5.5ft = 16.8 ft + 5.5ft = 22.3 ft
Can someone explain this step by step please
Answer:
x = - 2
y = 6
Step-by-step explanation:
The best way to do this is to put - 3x in for y in the second equation.
4x - 2(-3x) = - 20 Watch the signs. You have 2 minus signs.
4x - - 6x = -20 Change - - 6x to 6x
4x + 6x = - 20 Add
10x = - 20 Divide by 10
x = -20/10
x = - 2
============================
Find y
y = - 3x
y = -3 * -2
y = 6
Mel begins playing video games at the time on the left clock. If she stops playing video games at the time on the right clock, how many minutes did Mel spend playing video games?
Answer:
See Explanation
Step-by-step explanation:
The question is incomplete, as the required clocks are not given.
To answer this question, I will give an illustration of how to calculate the difference between times.
Note that: I assume you can read the time on a clock
Assume that:
[tex]Left\ clock = 2:15pm[/tex]
[tex]Right\ clock = 3:05pm[/tex]
The difference is calculated as:
[tex]Difference = Right\ clock - Left\ clock[/tex]
[tex]Difference = 3:05pm - 2:15pm[/tex]
From 2:15pm to 3:05pm is 50 minutes.
So:
[tex]Difference = 50\ minutes[/tex]
Another assumption:
[tex]Left\ clock = 2:15pm[/tex]
[tex]Right\ clock = 3:32pm[/tex]
The difference is calculated as:
[tex]Difference = Right\ clock - Left\ clock[/tex]
[tex]Difference = 3:32pm - 2:15pm[/tex]
For ease of calculation, we split the time to 2.
(1) From 2:15pm to 3:15pm
(2) From 3:15pm to 3:32pm
(1) From 2:15pm to 3:15pm: This is 1 hour
(2) From 3:15pm to 3:32pm: This is 17 minutes (i.e. 32 - 15)
So, the difference is:
[tex]Difference = 1hr + 17min[/tex]
[tex]Difference = 1\ hour\ 17minutes[/tex]

Tamia is getting balloons for her father's birthday party. She wants each balloon string to be 6 feet long. At the party store, string is sold by the yard. If Tamia wants to get 59 balloons, how many yards of string will she need?
Answer:
118 yards
Step-by-step explanation:
Tamia is getting balloons for her father's birthday party
She wants each balloon to be 6 feet long
Tamia wants to get 59 balloons
Therefore the yards of string needed can be calculated as follows
= 59×6
= 354 feet to yards
= 118 yards
Hence the number of yards needed is 118 yards

[tex]x=\dfrac{4\sqrt{3}}{3};\ y=\dfrac{8\sqrt{3}}{3}[/tex]
Step-by-step explanation:
The side ratios of a 30°-60°-90° triangle are ...
1 : √3 : 2
In your triangle, they are ...
x : 4 : y
In order to get these values, we need to multiply the reduced ratio by 4/√3 = (4√3)/3. Then we have ...
x : 4 : y = (4√3)/3 : 4 : (8√3)/3
and we can see that ...
x = (4√3)/3y = (8√3)/3It is less than 100 greater than 10 and you use a total of 7 base ten blocks to show this number the number of tens blocks is greater than the number of ones blocks one of the digits is 4

What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the number be = A
Now , let the ones digit of the number be = x
Let the tens digit of the number be = y
Now , the equation will be
The number of ten blocks = 7 base ten blocks
So , the equation is
x + y = 7
Now , one of the digits is 4
And , number of tens blocks is greater than the number of ones blocks
So , the next digit of the number is 3
4 > 3
Therefore , the number from the equation is 43
Hence , The value of the number is 43
