Answer:
36.656
Step-by-step explanation:
Calculate using trigonometry, Calculator may be required
Ok, so it's actually pretty easy
First of all, we know that all triangles' angles add up to 180 degrees
Here we can tell that we have one 90 degree angle and another 45 degree angle
Now, we can subtract both of these angles to then finalize that, the missing angle is equal to 45 degrees
Hope this helps :)

An elevator starts on floor 6 and ascends at a rate of
1 floor per second.
Andrew has $6 to spend at the arcade. He spends $1

Marco owed his father $150 and began paying him back $20 at the end of
each week, beginning November 1. Joni owed her father $130 and began
paying him back $15 at the end of each week, beginning on the same
day. What Marco owed his father in dollars at the end of n weeks can be
represented by f(n) = 150 - 20n. What Joni owed her father in dollars at the
-
end of n weeks can be represented by g(n) = 130 - 15n.
Find the value of n for which f(n) = g(n). What does that value mean in this
situation?
Answer:
The important clue here is when they say both The girls owe the same amount so what they mean is equate both the functions
so we get
150 - 20n = 130 - 15n
Now n gives us the number of weeks so solve for n
20n - 15n = 150 - 130
5n = 20
n = 4
Now check your solution
150-20(4) = 70
130 - 15(4) = 70
So our answer checks out after 4 weeks both girls who their dads the same amount of money .

Explain the error in Julie’s work in rewriting the radical expression.
Answer:
The negative numbers do not have square roots. Therefore the question does not have a solution. That is where Julie made a mistake.
Step-by-step explanation:
Answer:
-6
Step-by-step explanation:
First, let's take a look at this property:
[tex] \displaystyle \large{ \sqrt{a} \sqrt{b} = \sqrt{ab} }[/tex]
This only works for a and b ≥ 0.
As for a & b < 0 which results in Imaginary Number, we have to convert in 'i' form.
We know that:-
[tex] \displaystyle \large{ i = \sqrt{ - 1} }[/tex]
Thus:
[tex] \displaystyle \large{ \sqrt{ - 3} \cdot \sqrt{ - 12} = \sqrt{3} i \cdot \sqrt{12}i }[/tex]
Then we can multiply 12 & 3 in square root.
[tex] \displaystyle \large{ \sqrt{ - 3} \cdot \sqrt{ - 12} = \sqrt{36} {i}^{2} }[/tex]
We know that:
[tex] \displaystyle \large{ {i}^{2} = - 1}[/tex]
Convert i^2 to -1
[tex] \displaystyle \large{ \sqrt{ - 3} \cdot \sqrt{ - 12} = \sqrt{36}( - 1) } \\ \displaystyle \large{ \sqrt{ - 3} \cdot \sqrt{ - 12} = - \sqrt{36}}[/tex]
Then evaluate √36 which is 6.
[tex] \displaystyle \large{ \sqrt{ - 3} \cdot \sqrt{ - 12} = - 6}[/tex]
Therefore the answer should be -6.
Conclusion
Julie cannot use the √a√b = √ab property first because a & b both are < 0 and the property applies for a ≥ 0, b ≥ 0.
the parking garage charges an initial fee of 5$. Then they charge $10.50 per hour parked. You had to pay $68. How many hours did you park
The equation for the given situation is 5+10.50x=68.
Given that, the parking garage charges an initial fee of 5$.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Let the number of hours be x.
Garage charge $10.50 per hour parked. You had to pay $68.
So, equation is 5+10.50x=68
Therefore, the equation for the given situation is 5+10.50x=68.

A green bottle holds 8 35 ounces of water. A bluebottle holds 8 67 ounces of water. Write an inequality that compares the fractions and explain which bottle holds more.
PLEASE ANSWER THIS ASSSAAAPPP!!
Answer:
Blue bottle holds more.
Step-by-step explanation:
Given:
Green Bottle = 8 3/5 = 43/5
Blue Bottle = 8 6/7 = 62/7
Now:
we can write 43/45 as;
43/5 x 7/7 = 301/35 (1)
similarly, 62/7 = 62/7 x 5/5 = 310/35 (2)
Comparing both (1) and (2),
301/35 < 310/35
:. (301 < 310)
Hence,
Blue Bottle will hold more.
There were 56 runners to start a race. In the first half of the race, 1/4 of them dropped out. In the second half of the race, 3/7 of the remaining runners dropped out. How many runners finish the race?
Answer:
24 runners
Step-by-step explanation:
If 1/4 of the runners dropped out, then 1 - 1/4 or 3/4 continued on. 3/4 of 56 or 3/4 *56 is 42 runners left. Then, out of these 42, 3/7 dropped out. This means 1 - 3/7 or 4/7 of the runners remained. This means that 4/7 * 42 or 24 runners finished the race.

Plot the point (1.5, −3) on the coordinate plane.
Answer:
that it
Step-by-step explanation:
The Plot of the point (1.5, −3) on the coordinate plane is represented by Red dot in the attached graph.
How can we perceive cartesian coordinate plane?The cartesian coordinate plane is an infinite 2 dimensional plane. Any 2 dimensional figure can be drawn on an infinite 2d plane. Each of the point of a cartesian plane is tracked by a location.
The cartesian coordinate plane is the perpendicular distance of that point from the horizontal axis and vertical axis, usually named x-axis and y-axis. The location is written as; (a,b), where 'a' is that point's shortest distance from the y-axis and called x-coordinate of that point, and 'b' is that point's shortest distance from the x-axis, and called y-coordinate of that point.
Given
Point: (1.5, −3)
Required to Plot the point (1.5, −3) on the coordinate plane.

Is this correct? 3.81 estimated to a whole number is 4.
Answer:
yes it is correct
Step-by-step explanation:
Answer: Yes You are correct!
Step-by-step explanation:
If a number in the tenths place is greater than or equal to 5 then we round up. Ex: 1.90 would round to 2
If a number in the tenths place is less than or equal to 4 then we round down. Ex: 1.19 would round to 1
Since 8 is in the tenths place we round up. 3.81 would be 4 rounded to the nearest whole number.
