Answer:

6 glasses of water

Step-by-step explanation:

This is fairly simple as we already have the equation

x+y=10 ---> x=10-y

8x+12y=96

now substitute

80 -8y  + 12y = 96

4y= 16

y=4

if y = 4

x+4=10

x=6

Answer:

First graph option: A coordinate plane is shown with two lines graphed. One line passes through the y axis at 6 and through the x-axis at 6. The other line passes through the y axis at negative 3 and the x-axis at 1.5. The lines intersect at point 3 commas 3.

Step-by-step explanation:

i)  y=-x+6

ii) y=2x-3

The solution of the system of equations is found by equalizing the 2 equations:

-x+6=2x-3

-2x-x=-6-3

-3x=-9

x=-9/(-3)=3

i)  y=-3+6=3

ii) y=2(3)-3=6-3=3  

In graphs, this means that the lines intersect at (3, 3) ONLY

Answer: The graph where the lines intersect at (3, 3)

Yes.

Step-by-step explanation:

The sum of the interior angles of triangles always add up to 180 degrees. The third angle of the top triangle would be 27. The third angle of the bottom triangle is 63.

Triangles are similar if the angles are the same. Therefore the 2 triangles are similar.

Is there more to this question?

For the first inequality, x > -1

For the second inequality, x < -1

Step-by-step explanation:

5x - 29 > -34

add 29 to both sides

5x > -5

divide both sides by 5

x > -1

-----------------------------------------------------

2x + 31 < 29

subtract 31 from both sides

2x < -2

divide both sides by 2

x < -1

Answer: 340

Step-by-step explanation:

100 - 74 = 26%

26% = .26

x * .26 = 88.4

   /.26    /.26

x = 340

check

340 * .74 = 251.6

340 - 251.6 = 88.4

Answer:

8(4+2)

Step-by-step explanation:

Hi there! We know that 32+16=48 so all we have to do is find a expression that equals 48. 8(4+2)=48. 8(24+8)=256. 7(4+2)=42. 7(24+8)=224. Therefore, the expression that is equivalent to 32+16 is 8(4+2).

Answer:

[tex] \displaystyle \rm A_{ \text{c - pentagon}} =41[/tex]

[tex] \rm \displaystyle P _{ \rm c - pentagon} = 20+ 4 \sqrt{2} [/tex]

Step-by-step explanation:

we have a square and a triangle

we want to figure out the area and the perimeter of the pentagon

to figure out the area of the pentagon we can use the given formula:

[tex] \displaystyle \rm A_{ \text{c - pentagon}} = A_{ \text{squre}} - A_{ \text{triangle}}[/tex]

let's figure out [tex]A_{\rm square}[/tex]:

since the given shape is a square Every angle of its 90° Thus the triangle is a right angle triangle

therefore the height is 4

[tex] \displaystyle A _{ \rm triangle} = \frac{1}{2} \times b \times h[/tex]

substitute h and b

[tex] \displaystyle A _{ \rm triangle} = \frac{1}{2} \times 4 \times 4[/tex]

reduce fraction:

[tex] \displaystyle A _{ \rm triangle} = 2 \times 4[/tex]

simplify multiplication:

[tex] \displaystyle A _{ \rm triangle} = 8[/tex]

likewise square

[tex] \displaystyle A _{ \rm squre} = {s}^{2} [/tex]

substitute s:

[tex] \displaystyle A _{ \rm squre} = {7}^{2} [/tex]

simplify square

[tex] \displaystyle A _{ \rm squre} = 49[/tex]

hence,

[tex] \displaystyle \rm A_{ \text{c - pentagon}} =49- 8[/tex]

[tex] \displaystyle \rm A_{ \text{c - pentagon}} =41[/tex]

to figure out perimeter

let's figure out hypotenuse first

[tex] \displaystyle h = \sqrt{ {4}^{2} + {4}^{2} } [/tex]

[tex] \displaystyle h = \sqrt{ 16 + 16} [/tex]

[tex] \displaystyle h = 4 \sqrt{2} [/tex]

therefore,

[tex] \rm \displaystyle P _{ \rm c - pentagon} = 3 + 3 + 4 \sqrt{2} + 7 + 7[/tex]

[tex] \rm \displaystyle P _{ \rm c - pentagon} = 6 + 4 \sqrt{2} + 14[/tex]

[tex] \rm \displaystyle P _{ \rm c - pentagon} = 20+ 4 \sqrt{2} [/tex]

According to the discrete distribution given, the standard deviation is of 0.95.

The distribution is:

[tex]P(X = 1) = 0.29[/tex]

[tex]P(X = 2) = 0.44[/tex]

[tex]P(X = 3) = 0.19[/tex]

[tex]P(X = 4) = 0.06[/tex]

[tex]P(X = 5) = 0.02[/tex]

The expected value is given by the sum of each value multiplied by it's respective probability, hence:

[tex]E(X) = 0.29(1) + 0.44(2) + 0.19(3) + 0.06(4) + 0.02(5) = 2.08[/tex]

The standard deviation is the square root of the sum of the difference squared of each value and the mean, multiplied by it's respective probability, hence:

[tex]\sqrt{V(X)} = \sqrt{0.29(1-2.08)^2 + 0.44(2-2.08)^2 + \cdots + 0.02(5-2.08)^2} = 0.95[/tex]

The standard deviation is of 0.95.
