Answer:
Triangle = 10
Circle = 5
Two halves of Square = 2
Fourth answer: 20
Step-by-step explanation:
Figuring out the triangle first is easiest because since 3 triangles make 30, then each triangle must be 10.
Now, we have our second equation become 10 + C + C = 20, and we get C=5 after solving for the value of the circle.
Our third equation will be 5 + S + S = 13, which becomes 5+2S=13, 2S=8, and then S=4, so the value of a square is 4
Our fourth equation will be 10 + 5*(1/2)(4) = ?, and we see that half of 4 is 2, so we have 10 + 5(2) = 10 + 10 = 20 as our answer.
The value of the given expression x + yz will be 20.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
Let 'x' represents an equilateral triangle, 'y' represent a circle, and 'z' represents the right triangle. Then the equations are given as,
x + x + x = 30
3x = 30
x = 10
x + y + y = 20
10 + 2y = 20
y = 5
y + 2z + 2z = 13
5 + 4z = 13
z = 2
Then the value of the expression is calculated as,
x + yz = 10 + 5 × 2
x + yz = 10 + 10
x + yz = 20
The value of the given expression x + yz will be 20.

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.

2x² + 3 = 39 extracring square roots
Answers
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]

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]

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
Answers
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

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

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
