Solve for x and y.
You will have to show your work to get brainliest!
Answer:
For ∆1 , x = 20 , y = 10√2
For ∆2 , x = y = 11
Step-by-step explanation:
Here in the first right angled triangle one of the angles is 45°. And one of the known side is 20 . We need to find out the value of x and y.
Since two angles are 90° and 45° , therefore the third angle will be 45° . And as we know that the sides opposite to equal angles are equal. Therefore ,[tex]\rm\longrightarrow \underline{\underline{ x =20}}[/tex]
Again , we use ratio of sine to find y , as ,
[tex]\rm\longrightarrow sin45^o =\dfrac{p}{b}\\ [/tex]
[tex]\rm\longrightarrow \dfrac{1}{\sqrt2}=\dfrac{20}{y}\\ [/tex]
[tex]\rm\longrightarrow y =\dfrac{20}{\sqrt2}=\dfrac{2\times 10}{\sqrt2}\\ [/tex]
[tex]\rm\longrightarrow \underline{\underline{ y = 10\sqrt2}} [/tex]
[tex]\qquad\rule{200}2[/tex]
Again , in the second Triangle , we may use ratio of sine to find the value of y , as ;
[tex]\rm\longrightarrow sin45^o =\dfrac{p}{b}\\ [/tex]
[tex]\rm\longrightarrow \dfrac{1}{\sqrt2}=\dfrac{y}{11\sqrt2}\\ [/tex]
[tex]\rm\longrightarrow y =\dfrac{11\sqrt2}{\sqrt2}\\ [/tex]
[tex]\rm\longrightarrow \underline{\underline{ y = 11}} [/tex]
Again , we know that the sides opposite to equal angles are equal . Therefore here ,[tex]\rm\longrightarrow \underline{\underline{ x =11}}[/tex]
)) A cylinder has a height of 9 meters and a diameter of 34 meters. What is its volume?
Use a = 3.14 and round your answer to the nearest hundredth.
Answer:
Volume of a sphere is (pi)*(r^2)*(h), where r is raduis, h is height, and pi is 3.14.
Diameter is 24/2 = 12
We just need to plug everything in.
(3.14)*(12^2)*(14) = 6330.24

Find the value of x.
Answer:
75° = x°
Step-by-step explanation:
there are 4 right angles
so with the line being linear, the angle on each side is 15°. so you take
90° (right angle) - 15° (the inside angle) = 75°. or the outside angle
do 75 + 15 to check
Answer:
x=75°
Step-by-step explanation:
AG`D=90°
FG'D =15 vert. opp.angl
90-15=75
Which graph represents a system of equations with one solution?
Step-by-step explanation:
none of the graphs that we can see here.
the first are 2 parallel lines. they never cross, so there is no solution at all.
and the second one is seemingly only one line. well a line goes on infinitely, and every point on it is a solution to the line equation. so, this has infinite many solutions.

Describe the direction in which each object will accelerate. If the object won’t accelerate, write “no acceleration.” Explain what might be happening to each object in terms of its overall motion. (Will give the right answer brainillesit)
Answer:
The object will have a positive acceleration of 100N and it will travel up.
Step-by-step explanation:
300N - 200N = 100N
Therefore, 300N has greater value making the air balloon travel upwards toward the sky.

2x² + 3 = 39 extracring square roots
Answer:
x=9
Step-by-step explanation:
first, subtract 3 from both sides so 2x^2=36, then, divide both sides by 2 so x^2=18 and divide 18 by 2 and 9^2=18
Answer:
x = ± 3[tex]\sqrt{2}[/tex]
Step-by-step explanation:
2x² + 3 = 39 ( subtract 3 from both sides )
2x² = 36 ( divide both sides by 2 )
x² = 18 ( take square root of both sides )
x = ± [tex]\sqrt{18}[/tex] = ± [tex]\sqrt{9(2)}[/tex] = ± ( [tex]\sqrt{9}[/tex] × [tex]\sqrt{2}[/tex] ) = ± 3[tex]\sqrt{2}[/tex]

Solve for y
2(y + 2) = 62(y+2)=6
Answer:
y=-8
Step-by-step explanation:
2y+4=62y+124=6
2y-62y=124-4=6
-60y=120=6
divide both side by -60
y=120/-60=6
y=-2=6
y=-2-6
y=-8
Compare each side of the equation 65 ÷ 5 = 87 ÷ 3 to determine if it is true or false.

So, False
Answer:
The equation is false
Step-by-step explanation:
65 ÷5 = 13
87 ÷ 3 = 29
13 and 29 are not equal thus making the equation false.

Um cant figure out the second question
Answer:
£15
Step-by-step explanation:
There are 3 ways to get 7 out of the 12 possible outcomes, so the probability a player will win 30p is 1/4. That is a player will have expected winnings of (1/4)(30p) = 7.5p each time the game is played.
The school gains 20p from each player, but has an expected payout to the player of 7.5p, so the net gain per game to the school is ...
20p -7.5p = 12.5p
The gain to the school when 120 people play is ...
(120)(12.5p) = 1500p = £15 . . . . expected to be raised
A carpenter has wood that is 5x+2 feet long. How long is the wood after 2x-5 feet have been cut off. (type in your solution so i can learn from it thanks)
5x+2 - (2x - 5)

Help please!!! I really don’t know how to do this!
Answer:
I'm going to do 1 as an example and using what I've taught you, you have to do the rest. Hope my explanation helps.
Step-by-step explanation:
We are given the points (-2, -4) and (-1, -1)
We need to find the slope.
The equation to do so is y2 - y1 / x2 - x1
lest say:
-2 is x1
-4 is y1
-1 is x2
-1 is y2
-1 - (-4) / -1 - (-2)
3/1 = 3
slope (m) = 3
We already know the y-intercept is 2
The equation of a line is y = mx + b
For this problem we just have to substitute what we already know.
y = (slope)x + y-intercept
y = 3x + 2
*TIP*
If the y-intercept is negative, let's say: b = -5 (using slope 8)
the equation will be y = 8x - 5
Hope this helps. I wish you all the best. :)
3. A scientist recorded the movement of a pendulum for a period of time. The scientist began recording when
the pendulum was at its resting position. The pendulum then moved right (positive displacement) and left
(negative displacement) several times. The pendulum took 5 s to swing to the right and then return to its
resting position. The pendulum's furthest distance to either side was 7 in. Graph the function that represents
the pendulum's displacement as a function of time.
(a) Graph the function (include at leaſt one full cycle).
(b) Write an equation to represent the displacement of the pendulum as a function of time.

Use the graph of speed versus time to answer the questions about acceleration.
Which of the cars is speeding up? ______
Which of the cars is slowing down? ______
Which of the cars is maintaining a constant speed? ______
The car that is speeding up is car A.
The car that is slowing down is car C.
The car that is maintaining a constant speed is car B.
What is speed?Speed is the ratio of distance and time.
It shows how fast an object is moving at a given time.
We have,
From the graph, we see that,
Car A speed is increasing with time.
Car B is maintaining a constant speed with time.
Car C is decreasing its speed with time.
Thus,
Car A is speeding up.
Car C is slowing down

1. The table shows the prices of 3 boxes of laundry detergent of different sizes. Which size box costs the least per ounce? Explain your answer. Size Price 150 OZ 100 oz $18.97 $11.97 $8.97 56 OZ
The table is an illustration of unit rates
Box 2 has the least price per ounce
How to determine the least per ounce
The given parameters are:
Box 1 = $18.97 per 150 Oz
Box 2 = $11.97 per 100 Oz
Box 3 = $8.97 per 56 Oz
Divide the price by the sizes, to get the rates
[tex]Box 1 = \frac{18.97}{150} =0.126}[/tex]
[tex]Box 2 = \frac{11.97}{100} =0.1197}[/tex]
[tex]Box 3 = \frac{8.97}{56} =0.160[/tex]
By comparison, 0.1197 is the least
Hence, box 2 has the least price per ounce
