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.

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].

2(4x+5)=9(3x+2)? I need help

Answers

Answer:

[tex]x=-\frac{8}{19}[/tex]

Step-by-step explanation:

2(4x + 5) = 9(3x + 2)

Solve for x

___________________

We have an alrebaric expressio and are asked to solve for x, which to do this, we need to isolate x.

2(4x + 5) = 9(3x + 2)

Distribute :

(2(4x) + 2(5)) = (9(3x) + 9(2))

8x + 10 = 27x + 18

Subtract 10 from both sides :

8x = 27x + 8

Subtract 27x from both sides :

-19x = 8

8 = -19x

Divide both sides by -19 :

[tex]x=-\frac{8}{19}[/tex]

Tax for $ 31,850 is $ 4,386

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

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.

A: 600/30 = 20mm/min

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.

3 A garage is to be built with a skillion roof (a roof with a single
slope). The measurements are given in the diagram. Calculate
the pitch line length, to the nearest millimetre. Allow 500 mm
for each of the eaves.

Answers

Answer:

1e1e

Step-by-step explanation:

The pitch line length of the garage with the skillion roof, with the given dimensions and eave overhangs, is approximately 7.5 meters.

To calculate the pitch line length for the garage with a skillion roof, we need to consider the dimensions provided in the diagram and add the eave overhangs.

Let's assume the length of the garage is L meters, and the height from the top of the walls to the peak of the roof is H meters.

Calculate the pitch line length of the roof:

The pitch line length is the diagonal length of the triangular roof face. We can use the Pythagorean theorem to find it.

Pitch Line Length (PL) = √(L² + H²)

Add the eave overhangs:

The eave overhang is 500 mm on each side, so we need to add 1 meter (1000 mm) to the pitch line length.

Total Pitch Line Length (TPL) = PL + 1000

Now, let's calculate the pitch line length to the nearest millimeter.

For example, let's assume L = 6 meters and H = 2.5 meters.

Calculate the pitch line length (PL):

PL = √(6² + 2.5²)

PL = √(36 + 6.25)

PL = √42.25

PL = 6.5 meters

Add the eave overhangs:

TPL = 6.5 + 1

TPL = 7.5 meters

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
