Answer:

a = 4

Step-by-step explanation:

8 = 5a > - 12

8 + 12 = 5a > - 12 + 12

20 = 5a

20 ÷ 5 = 5a ÷ 5

a = 4

Check:

8 = 5(4) < 12

8 = 20 < 12

It is correct.

Answer:

4 exponent 3 or if you want the answer it is 64

Step-by-step explanation:

See the image below:)

Step-by-step explanation:

To find mean-

you add all the #'s together and then (/) them by the amount of the #'s

#5.   8, 2, 3, 5, 7

8+2+3+5+7

10+8+7

10+15

25

25/ 5

5

#6.   4, 1, 6, 3, 6, 4

4+1+6+3+6+4

5+9+10

5+19

24

24/ 6

4

The median is the (middle) you have to put the #'s in order least to greatest

#5.    2, 3, 5, 7, 8

cross one by one on both sides

3, 5, 7,

5

#6.   1, 3, 4, 4, 6, 6

3,4,4,6

4,4

4 (because in the middle of 4 and 4 well is 4) (if you had 5 and 6 left it would be 5.5)

The mode is the # that appear the most often in the set of data.

#5.  there is no more because there is one of each # there is none that has 2 or more (N/A)

#6.    1,3, 4, 4, 6, 6

the mode is 4 and 6

because those #'s have 2 or more and they are both at 2 so they are both the mode

The value of M from the equation; M+7.9=39 1/2 is; 31.6

The given equation is; M+7.9=39 1/2.

By simplification;

Hence, by cross product;

M = 31.6

The y-intercept of Function A is 1 unit greater than the y-intercept of Function B. Then the correct option is C.

A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

Some values of linear functions A and B are shown in the table and graph.

Function A

2       1.5

3      1.75

4        2

The function A is passing through (0, 1), then the equation of the line will be

1 = 0m + c

c = 1

Then the equation of the function A will be y = mx + 1.

From, the graph, it is clear that the y-intercept of Function A is 1 unit greater than the y-intercept of Function B.

Answer:

The radius of the circle is 6.

Explanation:

Take the square root of 36.

Answer:

The area of the cone not painted is approximately 196.35 cm²

Step-by-step explanation:

The question relates to similar shapes;

We have;

The base diameter of the cone, D₁ = 20 cm

The slant height of the cone, l₁ = 25 cm

The height at which the circle is drawn, 10 cm above the base, we have; l₂ = 25 cm - 10 cm = 15 cm

Let 'x' represent the diameter of the circle formed by the drawn circle, we have;

By similar triangles, we get;

D₁/l₁ = x/l₂

x = l₂ × D₁/l₁

20/25 = x/15

x = (20/25) × 15 = 12

The curved surface area of the cone, A = π·r·l

The area of the curved surface of the entire cone, A₁ = π·r₁·l₁

r₁ = D₁/2

Therefore, we get, A₁ = π × 20/2 × 25 = 250·π

A₂ = π × 15/2 × 25 = 187.5·π

The area of the cone not painted, A = A₁ - A₂

∴ A = 250·π - 187.5·π = 62.5·π

The area of the cone not painted, A = 62.5·π ≈ 196.35

The area of the cone not painted ≈ 196.35 cm²

Answer:

Step-by-step explanation:

Answer:

Step-by-step explanation:

Tiffany's distance is defined by the equation,

d = 2.5t

Here, d = distance of Tiffany from the starting line

t = time

a). d = 2.5t

    [tex]\frac{d}{t}=2.5[/tex]

   Tiffany's rate = 2.5 yards per second

b). Since, slope of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,

   Slope = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

   Therefore, slope of the line passing through two points (0, 10) and (10, 35)

   = [tex]\frac{35-10}{10-0}[/tex]

   = 2.5 yards per second

    Dion's walking rate = 2.5 yards per second

    Equation that defines the distance of Dione,

    d = mt + b

    Here, m = rate of the walking by Dione

    b = y-intercept

    Hence, equation will be,

    d = 2.5t + 10

c). If d = 60 yards

    For Tiffany,

    d = 2.5t

    60 = 2.5t

     t = 24 seconds

     For Dion,

     d = 2.5t + 10

     60 = 2.5t + 10

     2.5t = 50

      t = 20 seconds

     Therefore, Dion will take less time and finish first.

Answer:

32

Step-by-step explanation:

formula for area of a triangle = [tex]A=\frac{bh}{2}[/tex]

where b = base length and h = height

The triangle shown has the following the dimensions

base length = 2 + 6 = 8m

height = 8m

Using these dimensions we plug in the values into the formula

[tex]A=\frac{8*8}{2} \\8*8=64\\\frac{64}{2} =32[/tex]

Hence, the area of the triangle is 32 square meters

Answer:

This is a quadratic function

write it in the form [tex]a(x-h)^2+k[/tex]

h and k is the vertex, meaning the coordinate that is lowest or highest point depending on where the function is...pointing. You can see that the function is point up, so h is the x coordinate is at the bottom. the vertex coordinate is (9, -4), im sure you know why. In the formula, h means the x and k is the y. So that means that the h is 9 and k is -4.

now the think will be  [tex]a(x-9)^2-4\\[/tex]

now you find a by plugging one of the point, you can take the point (12, 4)

[tex]a(12-9)^2-4=4\\9a=8\\8/9=a\\[/tex]

so the equation

[tex]8/9 (x-9)^2 -4[/tex]
