Determine how much you would receive in return for a 8 month, $500 loan to a friend if you charged the 3% annual interest.

Answers

Answer:

You would receive $510.08 in return.

Step-by-step explanation:

In order to find the answer, you can use the formula to calculate the future value:

FV=PV*(1+i)^n

FV=future value

PV= present value= 500

i= interest rate=0.03/12=0.0025 per month

n= number of periods of time= 8

Now, you can replace the values in the formula:

FV=500*(1+0.0025)^8

FV=500*(1.0025)^8

FV=510.08

According to this, the answer is that you would receive $510.08 in return.

During a thunderstorm, 600 millimeters of rain fell in 30 min.

A. How fast did the rain fall, in millimeters per minute?

B. How fast did the rain fall, in millimeters per hour?

C. Which unit rate do you think is more useful? Explain your reasoning.

Sorry that I can only put 10 points. But please I really need help with this

Answers

A: 600/30 = 20mm/min

B: 1200 mm/hr (double the 30 min amount)

C: I think mm/hr is more useful because the actual rainfall can vary a lot from minute to minute. Looking at the amount over an hour averages that out.

Step-by-step explanation:

Her taxable income is $ 43,000 which lies in the tax category $ 31,850 to

$ 77,100.

Tax for $ 31,850 is $ 4,386

Plus 25% of the amount = ( $ 43,000- $ 31,850 )= $ 11,150 over

25 % of $ 11,150= $ 2,787.5

Six friends share 3/4 of a pound of roasted almonds. What fraction of a pound does each friend receive

Answers

Answer: 1/8 pounds of roasted almonds

Step-by-step explanation:

There are six friends and each of them are to receive and equal piece out of a 3/4 pound of roasted almonds.

The almonds each friend will get will therefore be the 3/4 pack divided by 6:

= 3/4 ÷ 6

= 3/4 * 1/6

= 3/24

= 1/8 pounds of roasted almonds

When dividing by a number, you can instead multiply by the inverse of that number.

The ratio of two sides of a parallelogram is 3:4 and the perimeter is 28 in. Find the lengths of the sides of the parallelogram.

Answers

Answer:

the lengths of sides are 8 and 6.

Step-by-step explanation:

Let us denote side lengths of the parallelogram as x and y.  

Then first condition can be written as x/y=3/4.

Second condition can be written as 2x+2y=28.

We can multiply both sides of the first equation by y and get x=(3y)/4.

Now we have x expressed in terms of y. It is convenient because we can substitute x in the second equation:

 

2(3y/4)+2y=28  

And we can solve it for y.

1.5y+2y=28

3.5y=28

y=8

What is left is to find x. We may use the expression for x again: x=(3*8)/4=6

Ans: the lengths of sides are 8 and 6.

4y - 7 = 15

Justify your answer

Answers

Given :

4y - 7 = 15

To Find :

Value of y = ?

Solution :

[tex] \tt \dashrightarrow 4y - 7 = 15[/tex]

[tex] \tt \dashrightarrow 4y = 15 + 7[/tex]

[tex] \tt \dashrightarrow 4y = 22[/tex]

[tex] \tt \dashrightarrow y = \cancel{\dfrac{22}{4}}[/tex]

[tex] \tt \dashrightarrow y = \dfrac{11}{2}[/tex]

[tex] \tt \dashrightarrow y = 5.5[/tex]

[tex] \large \underline{\boxed{\bf{y = 5.5}}}[/tex]

Hence, value of y = 5.5.

Answer: y = 5 ½ or y = 5.5

Step-by-step explanation:

4y - 7 = 15

Add 7 to both sides of the equation.

4y = 22

Divide both sides by 4

y = 5.5

Substitute y in the original equation.

4(5.5) - 7 = 15

22 -7 = 15

True.

What are the points on y-axis which are at a distance of 4 units from 4x+3y=12

Answers

Given:

The equation of line is

[tex]4x+3y=12[/tex]

To find:

The points on y-axis which are at a distance of 4 units from the given line.

Solution:

The point lie on the y-axis. So, their x-coordinate must be zero.

Let the points are in the form of (0,k).

The distance between a point [tex](x_0,y_0)[/tex] and a line [tex]ax+by+c=0[/tex] is

[tex]d=\dfrac{|ax_0+by_0+c|}{\sqrt{a^2+b^2}}[/tex]

The given equation can be written as

[tex]4x+3y-12=0[/tex]

The distance between (0,k) and [tex]4x+3y-12=0[/tex] is 4 units.

[tex]4=\dfrac{|4(0)+3(k)-12|}{\sqrt{4^2+3^2}}[/tex]

[tex]4=\dfrac{|0+3k-12|}{\sqrt{16+9}}[/tex]

[tex]4=\dfrac{|3k-12|}{\sqrt{25}}[/tex]

[tex]4=\dfrac{|3k-12|}{5}[/tex]

Multiply both sides by 5.

[tex]20=|3k-12|[/tex]

[tex]\pm 20=3k-12[/tex]

[tex]12\pm 20=3k[/tex]

[tex]\dfrac{12\pm 20}{3}=k[/tex]

Now,

[tex]k=\dfrac{12-20}{3}\text{ and }k=\dfrac{12+20}{3}[/tex]

[tex]k=\dfrac{-8}{3}\text{ and }k=\dfrac{32}{3}[/tex]

Therefore, the two points are [tex]\left(0,\dfrac{-8}{3}\right)\text{ and }\left(0,\dfrac{32}{3}\right)[/tex].
