Answer:

y= 1/5 x -1

Step-by-step explanation:

Find two points ( any two of the three given)

find the slope between   5,0   and   10, 1

    ( 1-0)/(10-5)   = m = slope   = 1/5

so the line is of the form   y = mx + b :

                                            y = 1/5 x + b     sub in any point to calculate 'b'

                                             1 = 1/5 (10) + b

                                                    b = -1

y = 1/5 x -1   is your answer

Answer:

Linear

Step-by-step explanation:

The equation is in the form y = mix + b, which means it is linear.

Answer:

The length of each side of square is 5ft.

Step-by-step explanation:

A composite figure is formed by combining a square and a triangle. Its total area is 32.5ft squared.

The area of the triangle is 7.5ft squared.Area of combined figure - area of triangle = area of square.

32.5 ft squared - 7.5 ft squared = 25 ft squared.

So, area of square = 25 ft squared.

Now, by putting the formula for getting the length of each side:

Let the side = a.

Area of square = 25 ft squared

Area of square = a²

Using square root both sides we get:

So, the side = 5 ft.

Therefore, the length of each side of square is 5ft.

Answer:

y-intercept= (0,7) and rate of change=

Step-by-step explanation:

The y-intercept of a graph is the point on the graph where it intersects the y-axis or where x=0. In this case it is (0,7) so that is the y-intercept. The rate of change is equal to y2-y1 divided by x2-x1. Basically, just pick 2 random points on the line and subtract their y coordinates, then subtract their x-coordinates and divide the answers with each other. So, one point is (0,7) and another point is (2,4). Therefore, rate of change is 7-4 divided by 0-2. This gives us a rate of change of -3/2

Find the required water volume using the volume of prism formula

Find the time required

Answer:

40 hours

Step-by-step explanation:

The swimming pool can be modeled as a rectangular prism.

Volume of a rectangular prism

  [tex]V = lwh[/tex]

where:

First, calculate the volume of water needed:

Given:

Substitute the given values into the formula and solve for V:

[tex]\implies V=10 \cdot 5 \cdot 2=100\:\: \sf m^3[/tex]

If the water flows as a rate of 2.5 m³/h, divide the volume by the rate to calculate how long it will take to fill the pool:

[tex]\implies \sf Time=\dfrac{Volume}{rate}[/tex]

[tex]\implies \sf Time=\dfrac{100}{2.5}[/tex]

Answer:

96

Step-by-step explanation:

80 + 16 = 96

Hi!

The area of the entire figure is 76 units squared.

NOTE: This question has two different shapes: a rectangle, and a triangle.

Rectangle Formula:

Length * Width = Area

[tex]LW=A[/tex]

Triangle Formula

(Base * Height) / 2 = Area

[tex]\cfrac{bh}{2}=A[/tex]

Let's first get the rectangle's area:

[tex]LW=A[/tex]

[tex]8*7=A[/tex]

[tex]56=A[/tex]

The area of the rectangle is 56.

Now, for the top triangle:

[tex]\cfrac{bh}{2} =A[/tex]

[tex]\cfrac{8*2}{2} =A[/tex]

[tex]8=A[/tex]

The area of the top triangle is 8.

Now, for the bottom triangle.

[tex]\cfrac{bh}{2} =A[/tex]

[tex]\cfrac{8*3}{2} =A[/tex]

[tex]12=A[/tex]

The area of the bottom triangle is 12.

Now, add them all together:

[tex]56+8+12=76[/tex]

the answer is a x equal to or greater than

Answer:

Surface Area = 96

Step-by-step explanation:

Area of Triangle: Area = 1/2 * Base * Height

Area = 1/2 * 6 * 2 = 6

Area = 6

Area of Rectange: Area = Length * Height

Area = 7 * 3 = 21

Area = 7 * 6 = 42

Area = 21

Surface Area = TopTri + BotTri + LeftRect + MidRect + RightRect

Surface Area = 6 + 6 + 21 + 42 + 21 = 96

Step-by-step explanation:

Triangle ABC is an equilateral triangle. it is equiangular. Therefore, the value of x is 60 degrees.

An equilateral triangle is a triangle that has all it sides and angles equal to each other.

An equilateral triangle is equiangular.

Therefore, the angles of an equilateral triangles are equal to 60 degree each.

Recall the sum of an angle of a triangle is 180 degrees.

Therefore, the value of angle x is 60 degrees.

Im maybe wrong but it might be that morgan earns morgans hourly rate on friday is 12$

Answer:

Jeremy is 12 years old

Step-by-step explanation:

Jeremy age=X

Sister age=Y

1. X+Y=29 (sum of their ages)

2. X=Y-5 (he is 5 years younger than his sister)

*Substitute eq 2 into eq 1

Y-5+Y=29

2Y=29+5

2Y=36 (divide both sides by 2)

Y =17

Substitute value of Y into eq 1 to find X

X+17=29

X=29-17

X= 12

Checking answer:

12+17=29

17-5=12

Hence why Jeremy is 12

The equation n = 30/t is an illustration of an inverse variation

The points on the graph are: (1,30), (2,15), (3,10) and (4,7.5)

The equation is given as:

n = 30/t

When t = 1, we have:

n = 30/1

n = 30

When t = 2, we have:

n = 30/2

n = 15

When t = 3, we have:

n = 30/3

n = 10

When t = 4, we have:

n = 30/4

n = 7.5

So the points on the graph are:

(1,30), (2,15), (3,10) and (4,7.5)

Answer:

  a)  1.6×10⁻⁶

  b)  2×10⁷

Step-by-step explanation:

You want the product or quotient in standard form of ...

The rules of exponents apply:

  (a^b)(a^c) = a^(b+c)

  (a^b)/(a^c) = a^(b-c)

A number is said to be in scientific notation if there is one digit to the left of the decimal point, and the multiplier is expressed to an appropriate power of 10. The power of 10 may need to be adjusted so the decimal point is in the correct place. In general, the power of 10 represents the place value of that most-significant digit.

In the US, a number is written in standard form as a sequence of digits with an optional decimal point. Integers are written so the least-significant digit has a place-value of 1.

Elsewhere, a number is written in standard form when it is written in scientific notation.

We have given both forms a number here, so you will need to choose the one that is standard form where you are.

The product is (8×2)×10^(-3-4) = 16×10^-7 = 1.6×10^-6

= 0.0000016

The quotient is (6/3)×10^(2-(-5)) = 2×10^7
