Amy has $725 in savings. She plans to save an additional $25 per month. What is the number of additional months Amy will need to save money in order to have exactly $1,000?

A.11

B.29

C.40

D.69

Answers

Answer:

11 months

Step-by-step explanation:

We know that Amy has a saving of $725 which she needs to make it up to $1000 by saving $25 each month.

This means that Amy needs to save $1000 - $725 = $275 more dollars to have exactly $1000 dollars.

If Amy saves $$25 each month, then the number of months that she needs to save money will be = 275 / 25 = 11 months

Step 1: Define

Point (4, 15)

Point (-1, -15)

Step 2: Find slope m

Substitute:                    [tex]m=\frac{-15-15}{-1-4}[/tex]Subtract:                       [tex]m=\frac{-30}{-5}[/tex]Divide:                          [tex]m=6[/tex]

What’s the question?

A stock loses $1.50 each day over a five-day period. What is the total change in the value of the stock at the end of five days? (remember to have two numbers after the decimal)

Answers

Given:

A stock loses $1.50 each day over a five-day period.

To find:

The total change in the value of the stock at the end of five days.

Solution:

Stock loses each day = $1.50

We know that, loss or reduction represented as negative change.

So, change in the value of the stock per day = -$1.50

Change in the value of the stock in 5 days = 5×(-$1.50)

                                                                       = -$7.50

Therefore, the change in the value of the stock at the end of five days is -$7.50. It means, the value of the stock loses $7.50 at the end of five days.

You have given an equal sided triangle with side length a. A straight line connects the center
of the bottom side to the border of the triangle with an angle of α. Derive an expression for
the enclosed area A(α) with respect to the angle (see drawing

Answers

Answer:

First case;

α < 90°

The area of the shaded triangle = 1/8·a²·sin(60)sin(α)csc(120 - α)

Second case;

α > 90°

The shaded area of the triangle =  1/8·a²·sin(60)sin(180 - α)csc(60 - α) + (a²·√3)/4

Step-by-step explanation:

First case;

α < 90°

The given parameters are;

The type of triangle = Equilateral triangle

The length of the sides of the triangle = a

The area of the triangle = 1/2×a×b×sinC

Where;

a and b are two legs (sides) of the triangle and C is the included angle

e/(sin(α)) = a/(2sin(120 - α)) = f/(sin60)

f = a·sin(60)/(2sin(120 - α))

The area of the triangle = 1/2 × a·sin(60)/(2sin(120 - α))×a/2 × sin(α)

By an online application, we have

1/2 × a·sin(60)/(2sin(120 - α))×a/2 × sin(α) = 1/8·a²·sin(60)sin(α)csc(120 - α)

The area of the triangle = 1/8·a²·sin(60)sin(α)csc(120 - α)

Second case;

α > 90°

The shaded area of the triangle = The area of the equilateral triangle - The unshaded area of the triangle

With an online tool, we have;

The shaded area of the triangle = (a²·√3)/4 - 1/8·a²·sin(60)sin(180 - α)csc(120 - (180 - α)

The shaded area of the triangle =  1/8·a²·sin(60)sin(180 - α)csc(60 - α) + (a²·√3)/4

Trust me

What is the slope of the line

Answers

Answer:

[tex]\huge\boxed{\frac{1}{2}}[/tex]

Step-by-step explanation:

In order to find the slope of a line, we need to find it’s rise over it’s run.

To do this, we need to find the change in y, and divide that by the change in x between any two given points.

[tex]\frac{\Delta y}{\Delta x}[/tex]

Two points on this graph that we can compare are are (-1, 3) and (1, 4).

From -1 to 1 is 2 points. So, the change in x is 2.

From 3 to 4 is 1 point. So, the change in y is 1.

Divide the change in y by the change in x:

[tex]1 \div 2 = \frac{1}{2}[/tex]

So the slope is 1/2.

Hope this helped!

the slope is 1/2
because the finding the slope is rather easy u find two points were the line passes through a point and count up and over till you get to the other point in this case u count up 1 and over 2 therefore it’s 1/2 and the line is higher on the right so it’s not negative
