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].
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.
Charlie runs laps around a track. The table shows how long it takes him to run different numbers of laps. How long would it take Charlie to run 9 laps?
Number of laps 2, 4, 6, 8, 10
Time (min) 16, 32, 48, 64, 80
Answers
Answer:
72
Step-by-step explanation:
It would take Charlie 72 minutes to run 9 laps. To solve the question find how long it takes to run 1 lap. Do this by dividing the number of minutes by the number of laps ran. For example, 16/2 equals 8, which means it took him 8 minutes to run one lap. To check you can divide the other values, like 32/4= 8 and 48/6 = 8. Then, multiply 8*9 it see how long it takes for him to run 9 laps. Therefore, the answer is 72 because 8*9=72.

A new phone costs $230 and the sales tax rate is 7%. What is the total cost of the camera after tax?
Answers
That's a question about percentage.
One way to represent percentage is using decimal number. In this way, 1 is equivalent to 100% and the other less percentages using numbers between 0 and 1.
Examples:
90% is equivalent to 0,90.5% is equivalent to 0.05. It's not 0.5 because 0.5 is equivalent to 50%.13.17% is equivalent to 0.1317.245% is equivalent to 2.45.If we want to know the percentage of a number, we should multiplacate the number by the porcentage in the decimal number form.
Examples:
55.90% of 200 is equal to: [tex]200 \times 0.5590 = 111.8[/tex]360% of 88 is equal to: [tex]88\times 3.6 = 316.8[/tex]In our problem, we have a phone with a increase of 7%. To solve that, it's important to perceive that $230 is equal to 100% and with a increase of 7%, we will pay 107%.
107% in the decimal number form is 1.07. With that information, we should multiplicate 1.07 by the original value and we will find the answer.
We know that [tex]230\times 1.07 = 246.1[/tex], therefore, the total cost of the phone after tax is $246.1.

Tax= $ 7,173.5
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

3.01 greater or less than 4?
Answers
Answer:
Less
Step-by-step it is greater by 1.01
Answer:
Less than
Step-by-step explanation:
3 itself is already less than 4. How can 3.01 be greater than 4? When comparing positive numbers, compare from left to right. If the place of the first number is larger (for example comparing 10 with 100), than the one with the larger place is greater (tenth place will always be smaller than hundreds place).
If the first digit of both numbers are the same place (for example 10 and 20), than look at the value, which one is greater? Since 2 is greater than 1, we know 20 is bigger than 10. This holds true regardless of what follows the 2 or 1. For example, 20 is still bigger than 19.987
The only exception is when we are comparing 20 and 19.999 (where 9 is repeated). I will not be proving it here, but 0.999 (9 repeated) is said to be equal to one. Which means that 20 and 19.999 (9 repeated) are equal.

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.

Question 3
For the triangle shown, calculate the perimeter
2.5 km
51.8°
62.1
Answers
Answer: The perimeter is 9.31km
Step-by-step explanation:
We have two triangle rectangles, and the perimeter of the complete triangle will be equal to the sum between the hypotenuses (of both triangles) and the bottom cathetus (of both triangles)
For a triangle rectangle and a given angle A (that is not the right angle)
Remember the relationships:
Sin(A) = (opposite cathetus)/(hypotenuse)
Cos(A) = (adjacent cathetus)/(hypotenuse)
Tan(A) = (opposite cathetus)/(adjacent cathetus)
With this, we can find the measures of each triangle in the imae.
The left triangle rectangle.
We have a cathetus (opposite) with length of 2.5km and A = 51.8°
Then the hypotenuse can be found by:
Sin(51.8°) = (2.5km)/(hypotenuse)
then:
hypotenuse = (2.5km)/sin(51.8°) = 3.18 km
And the bottom cathetus can be found with:
Tan(51.8°) = (2.5km)/(adjacent cathetus)
adjacent cathetus = (2.5km)/(Tan(51.8°)) = 1.98 km
For the other triangle, we have A = 62.1°, and the opposite cathetus is 2.5 km
We can use the same relationships than before:
Sin(62.1°) = (2.5km)/(hypotenuse)
then:
hypotenuse = (2.5km)/sin(62.1°) = 2.83 km
And the bottom cathetus can be found with:
Tan(62.1°) = (2.5km)/(adjacent cathetus)
adjacent cathetus = (2.5km)/(Tan(62.1°)) = 1.32 km
Then the perimeter of the complete triangle is:
Perimeter = 3.18 km + 1.98 km + 2.83km + 1.32 km = 9.31 km
Follow the steps and finish the solution.

WRITE AN EQUATION which describes the line that contains (9,4) and has an undefined slope.
Answers
Answer:
x = 9
Step-by-step explanation:
A line with an undefined slope will be a vertical line.
This means the equation of the line will be in x = form, because the line will only go through one x value.
Since the given point has the x value of 9, this means the line will only go through that value.
So, the equation of the line will be x = 9
