Martha is starting to save for a new laptop. She has been keeping track of her savings every day. The graph shows the number of days since she started keeping track and the amount of money in her savings.


She would like to figure out when she might have the $350 she needs to buy the laptop. She wonders if she could use her new math skills on linear regression to help figure it out.


What do you think? Would a linear model be appropriate for this data?

Step-by-step explanation:

===========================================================

Work Shown:

1 ft = 12 inches

1 ft, 2 inches = 12 inches + 2 inches .... add 2 inches to both sides

1 ft 2 inches = 14 inches

Now we'll use the scale ratio to help find the answer

(2 inches)/(5 miles) = (14 inches)/(x miles)

2/5 = 14/x

2x = 5*14

2x = 70

x = 70/2

x = 35

The distance between the two locations is 35 miles.

Answer:

360 square meters.

Step-by-step explanation:

You can split the polygon into three rectangles. Then you just have to figure out the area of each rectangle and add them together. The first rectangle has length of 12 and height of 10 so area of 120. The second rectangle has length of 32 and height of 6 so area of 192. The third rectangle has length of 8 and height of 6 so are of 48. 120 + 192 + 48 = 360

Answer:

Answer: (286/11) ÷ 2 = 13

Step-by-step explanation:

The quotient of 286 and 11 is given by the equation A = 26

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the first number be represented as x

Now , the value of x = 286

Let the second number be represented as y

The value of y = 11

Let the quotient be represented as A

The value of A is given by the equation ,

A = x/y

Substituting the values in the equation , we get

A = 286/11

The value of A = 26

Therefore , the value of A is 26

Hence , the equation is A = 26

Answer:

20 ounces of water

Step-by-step explanation:

Work backwards. David has 18 ounces, which is half of Charlie's. So, Charlie had 18•2=36 ounces. That was 3/5 of Barbara's water, so Barbara had 60 ounces. That is 3/4 of Amanda's water, so Amanda had 80 ounces. To find how much Amanda had left subtract 60 from 80 to get 20.

Answer:

A possible solution is that radius of cone B is 2 units and height is 36 units

Step-by-step explanation:

Step-by-step explanation:

The volume of a cone is given by

where

r is the radius

h is the height

Here we are told that both cones A and B have the same volume, which is:

And

(2)

We also know that cone A has radius 6 units:

and height 4 units:

For cone B, from eq.(2), we get

One possible solution for this equation is

In fact in this case, we get:

Therefore a possible solution is that radius of cone B is 2 units and height is 36 units, and we know that in this case Cone B has the same volume as cone A because it is told by the problem.

Answer:

  Vertex: (-1, 4)

  Maximum: f(-1) = 4

  Increasing: (-∞, -1)

  Decreasing: (-1, ∞)

Step-by-step explanation:

The equation can be written in vertex form by "completing the square."

First factor out the leading coefficient from the x-terms.

  f(x) = -(x² +2x) +3

Then add the square of half the x-coefficient inside parentheses. Add the opposite of that amount outside parentheses.

  f(x) = -(x² +2x +1) +3 +1

Write in vertex form.

  f(x) = -(x +1)² +4 . . . . . . . compare to a(x -h)² +k

You can see that the vertex is (h, k) = (-1, 4), and that the vertical scale factor 'a' is negative. This means the vertex is the maximum and the parabola opens downward.

The function will be increasing to the left of the maximum, decreasing to its right.

Vertex: (-1, 4)

Maximum: f(-1) = 4

Increasing: (-∞, -1)

Decreasing: (-1, ∞)

x = 16

m<R = 34°

Step-by-step explanation:

▪︎Its an isoceles triangle, so the two opposite angles are equal. m<S = <T.

▪︎So, you write them equal to each other and solve the linear equation to find x.

▪︎Substitute the x value into any of the angles and multiply by 2, (as they are equal) to find the sum, which is 146°.

▪︎Sum of all angles in a triangle is 180°,so

146° + m< R =180°

▪︎than minus 146° from 180°.

▪︎And you will have your answer.
