Suppose your dog posit $250 in a new savings account paying a Yield of 3% interest if the count is left alone how much money wil

Fed [463]

Answer:

The amount after a time period of 5 years is $287.5.

Step-by-step explanation:

Principal Amount deposited = $250

Time = 5 Years

Rate of interest = 3%

Now, SIMPLE INTEREST = $\frac{P \times R \times T}{100}$

⇒ $SI = \frac{250 \times 3 \times 5}{100} = 37.5$

or, the interest amount after 5 years = $37.5

Now, AMOUNT = PRINCIPAL + INTEREST

= $250 + $37.5 = $287.5

Hence the amount after a time period of 5 years is $287.5.

Find the constant of variation for the relationship f(x)= 30x.

trasher [3.6K]

For a direct variation, f(x) = kx. Therefore, for f(x) = 30x, constant of variation (k) = 30.

How do you solve the three forms: Slope Y-intercept form Standard Form Point slope form

Nostrana [21]

Answer:An equation in the slope-intercept form is written as

y=mx+b

Where m is the slope of the line and b is the y-intercept. You can use this equation to write an equation if you know the slope and the y-intercept.

Example

Find the equation of the line

Choose two points that are on the line

Calculate the slope between the two points

m=y2−y1x2−x1=(−1)−33−(−3)=−46=−23

We can find the b-value, the y-intercept, by looking at the graph

picture28

b = 1

We've got a value for m and a value for b. This gives us the linear function

y=−23x+1

In many cases the value of b is not as easily read. In those cases, or if you're uncertain whether the line actually crosses the y-axis in this particular point you can calculate b by solving the equation for b and then substituting x and y with one of your two points.

We can use the example above to illustrate this. We've got the two points (-3, 3) and (3, -1). From these two points we calculated the slope

m=−23

This gives us the equation

y=−23x+b

From this we can solve the equation for b

b=y+23x

And if we put in the values from our first point (-3, 3) we get

b=3+23⋅(−3)=3+(−2)=1

If we put in this value for b in the equation we get

y=−23x+1

which is the same equation as we got when we read the y-intercept from the graph.

To summarize how to write a linear equation using the slope-interception form you

Identify the slope, m. This can be done by calculating the slope between two known points of the line using the slope formula.

Find the y-intercept. This can be done by substituting the slope and the coordinates of a point (x, y) on the line in the slope-intercept formula and then solve for b.

Once you've got both m and b you can just put them in the equation at their respective position.

Nelson needs 3 and 3/4 cups of flour to make a loaf of bread and 2 and 2/3 cups of flour to make pretzels. How many cups of flou

matrenka [14]

Answer:

that is 6 and 5/ 12 cups of flour are required

Step-by-step explanation:

total number of cups required to make a loaf of bread

= 3 + ¾

making their denominators equal and that to 4

= 12/ 4 + 3/ 4

adding numerators

= (12 + 3)/ 4

= 15/ 4

total cups of flour required to make pretzels

= 2 + ⅔

making their denominators equal and that to 3

= 6/ 3 + 2/ 3

adding nunerators

= (6 + 2)/ 3

= 8/ 3

Total cups required:-

= 15/ 4 + 8/ 3

taking lcm of denominators to make the fractions equivalent

= {(15 × 3) + (8 × 4)}/ 12

= {45 + 32}/ 12

= 77/ 12

$6 \frac{5}{ 12}$

<em>that is 6 and 5/ 12 cups of flour are required</em>.
