Given
Distance of point A from the flagpole = 25feet
If angle of elevation is 30°
Required
Height of flagpole (opposite)
Using TOA
tan theta = opp/adj
tan30° = opp/25
opp = 25tan30°
opp = 14.4feet
Hence the height of flagpole when the angle of elevation is 30° is 14.4feet
If angle of elevation is 38°
Required
Height of flagpole (opposite)
Using TOA
tan theta = opp/adj
tan38° = opp/25
opp = 25tan38°
opp = 19.53feet
Hence the height of flagpole when the angle of elevation is 38° is 19.5feet
If angle of elevation is 45°
Required
Height of flagpole (opposite)
Using TOA
tan theta = opp/adj
tan45° = opp/25
opp = 25tan45°
opp = 25feet
Hence the height of flagpole when the angle of elevation is 45° is 25feet

Ronny is taking a jar with 50 dimes and quarters to Coin Master to redeem for dollar bills. The total value of his jar is $8.
Complete the system of equations below to represent the number of quarters, q, and the number of dimes, d, in the jar
The required system of the equation that represents the number of quarters, q, and the number of dimes, d, in the jar is 0.10d + 0.25q = 8 and d + q = 50.
Given that,
Ronny is taking a jar with 50 dimes and quarters to Coin Master to redeem for dollar bills. The total value of his jar is $8.
Simultaneous linear equations are two- or three-variable linear equations that can be solved together to arrive at a common solution.
Here,
Let the number of the dimes be d and the number of the quarters be q,
According to the question,
The total of the coins is 50,
d + q = 50,
And this coins values is $8,
0.10d + 0.25q = 50 [sinnce value of one dime = 0.10 and value of one quarter is 0.25]
Thus, the required system of the equation that represents the number of quarters, q, and the number of dimes, d, in the jar is 0.10d + 0.25q = 8 and d + q = 50.

The mean June midday temperature in Desertville is 36°C and the standard deviation is 3°C.Assuming this data is normally distributed, how many days in June would you expect the midday temperature to be between 39°C and 42°C?
Answer:
The value is [tex]E(X) = 4 \ days[/tex]
Step-by-step explanation:
From the question we are told that
The mean is [tex]\mu = 36^oC[/tex]
The standard deviation [tex]\sigma = 3^oC[/tex]
Generally the probability that in June , the midday temperature is between
39°C and 42°C is mathematically represented as
[tex]P(39 < X < 42) = P(\frac{39 - 36}{3} < \frac{X - \mu }{\sigma} < (\frac{42 - 36}{3} )[/tex]
[tex]\frac{X -\mu}{\sigma } = Z (The \ standardized \ value\ of \ X )[/tex]
[tex]P(39 < X < 42) = P(1 < Z <2 )[/tex]
=> [tex]P(39 < X < 42) = P(Z < 2) - P( Z <1 )[/tex]
From the z table the area under the normal curve to the left corresponding to 1 and 2 is
P(Z < 2) = 0.97725
and
P(Z < 1) = 0.84134
[tex]P(39 < X < 42) = 0.97725 - 0.84134[/tex]
=> [tex]P(39 < X < 42) = 0.13591[/tex]
Generally number of days in June would you expect the midday temperature to be between 39°C and 42°C
[tex]E(X) = n * P(39 < X 42 )[/tex]
Here n is the number of days in June which is n = 30
[tex]E(X) = 30 * 0.13591[/tex]
=> [tex]E(X) = 4 \ days[/tex]

solve for x and y graphically, 2y= 3x+1 and y=2x+3
Answer:
[tex](-\frac{1}{3},\frac{1}{2} )[/tex] , [tex](-\frac{3}{2} ,3)[/tex]
Step-by-step explanation:
2y = 3x + 1
y = 2x + 3
Graph 2y = 3x + 1.
Divide each term by 2 and simplify.
[tex]y=\frac{3x}{2}+\frac{1}{2}[/tex]
Rewrite in slope-intercept form.
[tex]y=\frac{3}{2}x+\frac{1}{2}[/tex]
Use the slope-intercept form to find the slope and y-intercept.
Find the values of m and b using the form y = mx + b.
[tex]m=\frac{3}{2}[/tex]
[tex]b=\frac{1}{2}[/tex]
The slope of the line is the value of m, and the y-intercept is the value of b.
Slope: [tex]\frac{3}{2}[/tex]
y-intercept: [tex](0,\frac{1}{2} )[/tex]
Any line can be graphed using two points. Select two x values, and plug them into the equation to find the corresponding y values.
Find the x-intercept.
x-intercept(s): [tex](-\frac{3}{2},0 )[/tex]
y-intercept(s): (0, 3)
Create a table of the x and y values.
_x_|_y_
[tex]-\frac{3}{2}[/tex] | [tex]0[/tex]
[tex]0[/tex] | [tex]3[/tex]
Graph the line using the slope and the y-intercept, or the points.
Slope: 2

Answer:
45 units squared
Step-by-step explanation:
Basically you know that two parts of the square is equal to a whole, as 50 plus 50 is 100.
So on the left diagonal, it is equal to 3 units squared, since there are 6 parts and each unit diagonal is equal to 1/2 of a square.
On the right side, there are also 3 units squared, since there are 6 parts and blah blah blah.
Even if it looks different, two partial squares will still add up to one whole square. So the diagonals are equal to 6 units.
Then you can add up your full squares that you already know of so there are 9 units on the bottom row and another 9 on top.
Then you add 7 for the third layer and 6 more on the next.
There are 4 on the next layer and 3 and another square.
So 9 + 9 + 7 + 6 + 4+ 3 + 1.
That is 39.
But you may say: BUT WAIT SCOTTY THERE IS ANOTHER 6
me: oh yah i frgot bro thanks m8
So since there is another 6 more units, it is 45 since 39 + 6 is 45.
Hope this helps boi

300x + 6,250=10,000
Answer:
x= 25 /2 and/or 12.5
Step-by-step explanation:
Let's solve your equation step-by-step.
300x+6250=10000
Step 1: Subtract 6250 from both sides.
300x+6250−6250=10000−6250
300x=3750
Step 2: Divide both sides by 300.
300x /300 = 3750 /300
x= 25 /2
Answer: X is 3450
