Right triangles are triangles with a measure of 90 degrees
The value of x is 76/11
How to calculate x in the triangleThe equation is given as:
sin (3x+5) = cos (8x+9)
To solve for x, we make use of the following theorem
If sin(A) = cos(B), then
A + b = 90
So, we have:
3x + 5 + 8x + 9 = 90
Collect like terms
3x + 8x = 90 - 5 - 9
Evaluate the like terms
11x = 76
Divide both sides by 11
x = 76/11
Hence, the value of x is 76/11

The area of this polygon is 228 square meters
What is the length of the side labeled with a question mark
Enter your answer in the box
Answer: 7
Step-by-step explanation:
Let the unknown length be x
Cut the polygon into 2 pieces
6 * 24 + x * (18 - 6) = 228
144 + 12x = 228
12x = 84
x = 7
The length of the side labeled with a question mark in the given polygon is 7 meters.
What is area?Area is the amount of space occupied by a two-dimensional figure. In other words, it is the quantity that measures the number of unit squares that cover the surface of a closed figure. The standard unit of area is square units which is generally represented as square inches, square feet, etc.
Given that, the area of this polygon is 228 square meters.
We know that, the area of a rectangle is Length×Breadth
Area of a large rectangle = 24×6
= 144 square meters
Let the length of unknown side be x.
Area of a small rectangle = 12×x
Total area = Area of a large rectangle+Area of a small rectangle
228=144+12x
12x=228-144
12x=84
x=84/12
x=7 meters
Therefore, the length of the side labeled with a question mark is 7 meters.

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]

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

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]

Diane flipped a coin 600 times and it landed heads up 240 times. What is the relative frequency of the coin landing heads up based on the results of this experiment?
4%
6%
40%
60%
Answer:
40%
Step-by-step explanation:
Flips 600 times, that's the total flips. ###/600
Heads flipped 240 times, and that's what you're looking for. 240/600
240/600 simplified is 2/5 (0.4)
You're looking for a frequency/percentage so you're looking at the decimal
Decimal number = Percentage

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

Recycled CDs, Incorporated, offers a choice of 5 used CDs for $20, with each additional CD costing $6. Write a cost function for purchasing 5 or more CDs. What will the cost of buying 9 CDs be? Let x represent the number of CDs over 5.
the answer will be
48$ dollars
Answer:
20 + 6x
$44
Step-by-step explanation:
So 5 CD's for 20 dollars is $4 ea. then each one added will be +6 with the variable (x).
so you can't have the first 5 becuase x is used for every one OVER 5.
So
$ or price = 20 + 6x

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. :)
