1. Find the length of the missing side. Round your answer to the nearest
tenth if needed. *
x

9
Answer:
x = 15Step-by-step explanation:
Since the triangle is a right angled triangle we can use Pythagoras theorem to find the missing side x
Using Pythagoras theorem we have
a² = b² + c²
where
a is the hypotenuse
b and c are the other two sides
So we have
[tex] {x}^{2} = {12}^{2} + {9}^{2} \\ {x} = \sqrt{ {12}^{2} + {9}^{2} } \\ x = \sqrt{144 + 81} \\ x = \sqrt{225} [/tex]
We have the final answer as
x = 15Hope this helps you
A line segment has the endpoints V(–3, –5) and W(16, –10). Find the coordinates of its midpoint M.
Answer:
(6.5, -7.5)
Step-by-step explanation:
Use the midpoint formula (x1 + x2) / 2 , (y1 + y2) / 2
Plug in the points:
(-3 + 16) / 2 , (-5 - 10) / 2
13/2 , -15/2
6.5, -7.5
So, the coordinates of midpoint M are (6.5, -7.5)
The Fairy Tale Spectacular is coming to town. Admission to the fair costs $32.50 and each ride costs $0.80. You have $50 to spend at the Fairy Tale Spectacular including admission. What is the maximum number of rides you can enjoy?
Answer:
21 rides
Step-by-step explanation:
let x = number of rides you can ride
32.50 + 0.80x [tex]\leq[/tex] 50
subtract 32.50 from both sides
0.8x [tex]\leq[/tex] 17.5
divide the left and right by 0.8
x [tex]\leq[/tex] 21.875
this means you can ride 21 times, because you can't ride a ride unless you can afford the whole cost
how to check; 32.50 + 0.8(21) is 49.30 and 80 cents more would go over your 50 dollar spending limit

How many gallons of a 60% antifreeze solution must be mixed with 70 gallons of 20% antifreeze to get a misture that is 50% antifreeze? Use the she-step method
Answer:
210 gaL 60 % Antifreeze IIStep-by-step explanation:
In the problem, there are two types of antifreeze
antifreeze I and
antifreeze II
antifreeeze I 20 ----70 gal
Antifreeze II 60 ----- x gal
Total 50 ---------------- (70 + x ) gal
20*70+60*x=50(70+x)
1400+60x=3500+50x
60x-50x=3500-1400
10x=2100
x= 210
x=210 gaL 60 % Antifreeze II

(-1)^39=?
Answer:
-1
Step-by-step explanation:
The total number of minus signs is odd, so the product is negative.
(-1)^39 = -(1^39) = -1
Answer:
See below
Step-by-step explanation:
So for this one we can estimate
-1^1=-1
-1^2=1
-1^3=-1
............
And so on
The pattern shown here is that if it is odd then the answer is -1 and the answer is 1 if it is even
So think..
Is 39 odd or even?
39 is odd so the answer is -1
Also you can calculator it

find the measure of the angle marked with a? Using the inverse trig functions. Round your answer to the nearest degree.
Answer: 52°
Step-by-step explanation:
[tex]\sin \theta=\dfrac{\text{side OPPOSITE of angle}}{\text{HYPOTENUSE}}\\\\\\\sin \theta =\dfrac{23}{29}\\\\\\.\quad \theta=\sin ^{-1}\bigg(\dfrac{23}{29}\bigg)\\\\\\.\quad \theta =52.47^o[/tex]
Rounded to the nearest degree: Ф = 52°
Step-by-step explanation:
Hey there!
Here;
The figure given is a Right angled triangle.
Let the unknown angle be a refrence angle.
Now,
p = 23
h = 29
In ratio of sin there is 'p' and 'h'. So, using sin ratio.
[tex] \sin( \alpha ) = \frac{p}{h} [/tex]
[tex] \sin( \alpha ) = \frac{23}{29} [/tex]
[tex] \alpha = { \sin}^{ - 1} (0.7931034)[/tex]
[tex] \alpha = 52.47°[/tex]
Therefore the the angle is 52°.
Hope it helps..
What is the vertex of f(x) = |x + 8| – 3?
Answer:
(-8,-3)

Answer:
Quantitative data
Step-by-step explanation:
When we measure something, then we can quantify them. By also making a count, we are trying to quantify a particular entity.
Now in this case, we know that age is something we can quantify or measure. By nothing the difference between the year of birth and the present year, we can simply give the number of years or simply how

In a run-off election between two candidates, a total of 25,200 votes were cast. If 300 voters had switched

actually receive?
Step-by-step explanation:
yikes that's hard GG bro
Answer:
The winner received 12,800 votes and the loser received 12,400.
Step-by-step explanation:
Divided the votes in half, then took 100 votes from the winner, defined W, and added 100 to the loser, defined L to give the Loser a lead of 200. Then switch 300 votes from the losers number to the winner. You'll end up with 12,800 and 12,400 and you can check by switching 300 voters from winner (12,800) to loser (12,400) to make the loser win by 200 votes. 12,800 and 12,400 also add up to 25,200.

Correct Question:
Type the correct answer in the box. Use numerals instead of words. Consider this expression. [tex]\sqrt{a^2} - 7 + |b|[/tex] When a = 2 and b = -4, the value of the expression is
Answer:
[tex]\sqrt{a^2} - 7 + |b| = -1[/tex]
Step-by-step explanation:
Given
[tex]a=2[/tex]
[tex]b = -4[/tex]
Required
Determine [tex]\sqrt{a^2} - 7 + |b|[/tex]
To solve this, we simply substitute the values of a in the given expression
[tex]\sqrt{a^2} - 7 + |b|[/tex]
[tex]\sqrt{a^2} - 7 + |b| = \sqrt{2^2} - 7 + |-4|[/tex]
Express 2² as 4
[tex]\sqrt{a^2} - 7 + |b| = \sqrt{4} - 7 + |-4|[/tex]
Express square root of 4 as 2
[tex]\sqrt{a^2} - 7 + |b| = 2 - 7 + |-4|[/tex]
[tex]|-4| = 4[/tex]
So, we have
[tex]\sqrt{a^2} - 7 + |b| = 2 - 7 + 4[/tex]
[tex]\sqrt{a^2} - 7 + |b| = -1[/tex]
Hence, the result of the expression is -1
