Answer:
-9,4.5,90
Step-by-step explanation:
9) [tex]\frac{12xy}{x-y}[/tex]
So you basically substitute the values in for x and y which give you
[tex]\frac{12(3)(-1)}{3-(-1)}[/tex]
[tex]\frac{12(-3)}{3+1}[/tex]
[tex]\frac{-36}{4} \\-9[/tex]
10) Same thing:
[tex]\frac{4xy}{2x} \\\\\frac{4(3)(9)}{2(3)} \\\\\frac{4(27)}{6} \\\\4.5[/tex]
11) Same for this:
[tex]\frac{2}{3}(9x+xy)\\\\ \frac{2}{3}(9(5)(3)\\\\\frac{2}{3}( 135)\\[/tex]
3*45=135
[tex]2(45)\\90[/tex]

Answer:
7.5 %
Step-by-step explanation:
31.50/420 = 0.075 = 7.5 %
Answer:
7.5% commission
Step-by-step explanation:
420 x r = 31.50
420r = 31.50
r = 31.50/420

Answer:
C= 27
G= 37
J=57
Z= 1
Step-by-step explanation:
These are the degrees because of the Triangle Sum Theorem which states that The sum of the measures of the angles in a triangle is 180°. So angle C for example is 27 because angle A is 53 and angle B is 100 add both of those and you get 153 so our equation would be 153+c=180, c being the angle, so then to solve this you do do 180-153 and that equals 27 so therefore, 153+27=180. This process applys to all the other angles as well ^w^

There are 24 children at the skate park. Seven of them are on bikes, nine of them are on skateboards, and the rest are on inline skates (4 wheels per skate). How many wheels are at the skate park?
a. 24
b. 96
c. 114
d. 8
Answer:
C. 114
Step-by-step explanation:
bikes have 2 wheels
skateboards have 4 wheels
incline skates have 8 wheels in total
7*2 = 14
9*4 = 36
8*8 = 64
if you add all of these up you get 114 wheels in total. 8*8 was from 24-7-9 = 8

Consider −9x^3-12x^2-4x. Factor out x.
x(−9x^2−12x−4)
Consider −9x^2−12x−4 Factor the expression by grouping. First, the expression needs to be rewritten as −9x^2+ax+bx−4. To find a and b, set up a system to be solved.
a+b=−12
ab=−9(−4)=36
Since ab is positive, a and b have the same sign. Since a+b is negative, a and b are both negative. List all such integer pairs that give product 36.
−1,−36
−2,−18
−3,−12
−4,−9
−6,−6
Calculate the sum for each pair.
−1−36=−37
−2−18=−20
−3−12=−15
−4−9=−13
−6−6=−12
The solution is the pair that gives sum −12.
a=−6
b=−6
Rewrite −9x^2−12x−4 as (−9x^2−6x)+(−6x−4).
(−9x^2−6x)+(−6x−4)

Solve for x:
Solve for y:
Answer:
x = 12
y = -2
Step-by-step explanation:
In a parallelogram, the sides opposite each other are equal.
Hence: PQ = SR and PS = QR
2x + 12 = 4x - 12
Rearrange to make x's on one side and the numbers on the other
4x - 2x = 12 + 12
2x = 24
x = 12
____________
y + 25 = 6y + 35
Rearrange to make y's on one side and the numbers on the other
6y - y = 25 - 35
5y = -10
y = -2
A scuba diver descends 80 feet, rises 25 feet, descends 12 feet, and then rises 52 feet where he will do a safety stop for five minutes before surfacing. At what depth did he do his safety stop?
Answer:
15 ft
Step-by-step explanation:
At 15 feet below the surface, the scuba diver did his safety stop.
What is the surface?The surface is the common region between two different mediums. Here in the question surface is the common region between seawater and above seawater.
Let us denote the values of descending by negative sign and rising by positive sign and we sum up all the values together.
∴ [ - 80 + 25 + (-12) + 52 ] feet.
= (-80 + 25 - 12 + 52) feet.
= - 15 feet.
So, at 15 feet below the surface the scuba diver dis his safety stop.

Step-by-step explanation:
Remark
By corresponding angles and vertical angles, these two angles are equal.
Equation
-1 + 14x = 12x + 17 Subtract 12x from both sides
Solution
-1 + 14x - 12x = 12x - 12x + 17
-1 + 2x = 17 Add 1 to both sides
-1+1 + 2x = 17 + 1
2x = 18 Divide by 2
2x/2 = 18/2

During the Dallas marathon, a helicopter monitors the racers at a height of 527 feet. The pilot can see the runners that are in first and second place. The angle of elevation from the runner in first place to the helicopter is 45 degrees. The angle of elevation from the runner in second place to the helicopter is 60 degrees. What is the distance from the runner in 2nd place to the point directly below the helicopter? Round your answer to the hundredths place.
The distance from the runner in 2nd place to the point directly below the helicopter is given as follows:
304.26 feet.
What are the trigonometric ratios?The three trigonometric ratios are defined as follows:
Sine of angle = length of opposite side divided by the length of the hypotenuse.Cosine of angle = length of adjacent side divided by the length of the hypotenuse.Tangent of angle = length of opposite side divided by the length of the opposite side.The parameters for this problem are given as follows:
Distance of x adjacent to the angle of 60º.Opposite side of 527 feet, which is the height.Hence the distance is obtained applying the tangent function as follows:
tan(60º) = 527/x
x = 527 / tangent of 60 degrees
x = 304.26 feet.

Jomaya has $15. She saves $2 every day. How many days will it take Jomaya to save $25?
Answer: 12.5
Step-by-step explanation: 2times 12.5 is 25
Answer:
5 days
Step-by-step explanation:
To find out this question, we can subtract the amount she wants to get, 25, by the amount she has, 15:
25 - 15 = 10
So, Jomaya wants to save up $10, and because she saves $2 every day, we can divide:
10 / 2 = 5
So, it will take Jomaya 5 days to save $25

m∠1 = 93.5°
Step-by-step explanation:
By theorem of intersecting chords inside a circle,
If two chords intersect inside a circle, angle formed between the chords measure half the sum of the measures of the intercepted arcs.
m∠1 = [tex]\frac{1}{2}(92+95)[/tex]
= [tex]\frac{187}{2}[/tex]

if the ratio of two numbers is 2;3 and their G.C.F is 8 what is their L.C.M
Expert Answer:
Since the numbers are in the ratio 3:4 then let the numbers be 3x and 4x.
Thus the H.C.F. of the two numbers = x.
But the H.C.F is given as 4.
So, x = 4.
So, the numbers are,I
3x = 3 x 4 =12
And
4x = 4 x 4 = 16
We know,
H.C.F x L.C.M = Product of the two numbers
4 x L.C.M = 12 x 16
L.C.M = 48
Thus, the L.C.M of 12 and 16 , 48
