Y varies directly as x. If x=6 when y=36 find x when y=72

Answers

Answer 1

Answer:

x= 12

Step-by-step explanation:

Y[tex]\alpha[/tex] X

Let the constant be k

For the proportionality sign to be gone,a constant has to be introduced.

Since y varies directly,the constant ( k) will multiply x

Y= kx

Substitute for x=6 and y=36 to find k

36=6x

x = 36/6 = 6

To find the value of x,substitute for k = 6 and y = 72

72= 6x

x = 72/6

x=12

What is Slope of Line?

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

We know that the product of slopes of perpendicular lines is -1.

mM=-1

m is slope of one line and M is the slope of perpendicular line.

M=-1/m

y=1/3x+4

The perpendicular line is y=-3x-4

y=2/5x-7

The perpendicular line is y=-5/2x+7

y=-5/2x+8

The perpendicular line is y=2/5x+6

y=-2x+6

The perpendicular line is y=1/2x+3

y=7/5x-9

The perpendicular line is y=-5/7x-11.

Hence, the lines with corresponding perpendicular lines are

y=1/3x+4---> y=-3x-4

y=2/5x-7-----> y=-5/2x+7

y=-5/2x+8----->y=2/5x+6

y=-2x+6---->y=1/2x+3

y=7/5x-9-----> y=-5/7x-11.

Compare the investment below to an investment of the same principal at the same rate compounded annually.
principal: $6,000, annual interest: 6%, interest periods: 6, number of years: 18

Answers

The investment compounded annually has a higher final value than the investment you described because the annual compound interest rate is higher.

What is compound interest?

Compound interest is a type of interest that is calculated on the initial principal of an investment as well as any accumulated interest. In other words, compound interest is interest that is earned on both the original principal and on the accumulated interest from previous periods.

To compare the investment you described to an investment of the same principal at the same rate compounded annually, we need to calculate the final value of each investment after 18 years.

For the investment you described, the final value can be calculated using the formula:

FV = P(1 + r/n)^(nt)

Where FV is the final value, P is the principal, r is the annual interest rate, n is the number of interest periods per year, and t is the number of years.

Plugging in the values given in the problem, we get:

FV = $6,000(1 + 0.06/6)^(6*18) = $6,000(1.01)^108 = $12,688.80

For the investment compounded annually, the final value can be calculated using the same formula, but with n = 1:

FV = $6,000(1 + 0.06/1)^(1*18) = $6,000(1.06)^18 = $15,848.75

Hence, the investment compounded annually has a higher final value than the investment you described because the annual compound interest rate is higher. The difference in final value between the two investments is $15,848.75 - $12,688.80 = $3,159.95.

My Truck Takes 50 Gallons of gas. I used 20⅔ gallons on Monday. 9¼ on Tuesday. And 2½ on Wednesday. How many Gallons of gas do i still have in my truck?​

Answers

Answer:

17 7/12 gallons of gas.

Step-by-step explanation:

Set the fractions to like denominators. It'll make it a hell of a lot easier to add.

20 2/3rds = 20 8/12

9 1/4ths = 9 3/12

2 1/2 = 2 6/12

Adding those together gets you 31 17/12 which is 32 5/12 simplified.

Which angles are coterminal with 3л/2?
Select each correct answer.

A. 11л/2

C. -7л/-2
D. л/2

Answers

Answer:

  A, C

Step-by-step explanation:

You want to know which answer choices are angles that are coterminal with 3π/2.

Coterminal

Angles are coterminal when their terminal rays lie in the same position. In general, any angle will be coterminal with angles that are an integer multiple of 2π added to the original.

That is, an angle is coterminal with all angles that have the same value modulo 2π.

For the given angle and each of the answer choices, the attachment calculates the coefficient of π modulo 2. The ones that match the given angle are ...

 A. 11π/2 mod 2π = 3π/2

  C. -7π/-2 mod 2π = 3π/2

__

Additional comment

Both -π/-2 and π/2 match the angle π/2, which is not the same as 3π/2.

Of course, the minus signs in numerator and denominator cancel, so -7π/-2 is the same as 7π/2.

Step-by-step explanation:

Tom wants to know if a 70 cm chest will fit in the space left by a 67 in bed in a room 86 in wide.

Available space

The space available is 86 in -67 in = 19 in.

Space needed

Ratio is used for comparing two quantities of the same kind. The ratio formula for two numbers, a and b is expressed as a : b or a/b. When two or more ratios are equal, they are said to be in proportion. The concept of ratio and proportion is based on fractions.

Proportion refers to the equality of two ratios. Two equivalent ratios are always in proportion. Proportions are denoted by the symbol (: :) and they help us to solve for unknown quantities. In other words, proportion is an equation or statement that is used to depict that the two ratios or fractions are equivalent.

In this problem, we know that he has 2 bags of cornmeal

1 bag of cornmeal = 25 serving

2 bags = x

x = 2 * 25 = 50 servings

When making muffins, he needs 2.5 cups in a batch

But 3/4 cup = 1 serving

x cups = 50 serving

x = 50 * 3/4

x = 37.5 cups

A TPN solution contains 8.25 % amino acids it. If the patient needs 75 grams of protein per day, how much of the TPN solution should the patient receive per day?

Answers

The patient should receive 909 mL of the TPN solution per day.

To determine the amount of the TPN solution the patient should receive per day, we need to use the following formula:

amount of TPN solution = (grams of protein needed / percentage of amino acids in TPN solution) × 100

In this case, we are given that the TPN solution contains 8.25% amino acids and that the patient needs 75 grams of protein per day. Substituting these values into the formula, we get:

amount of TPN solution = (75 / 8.25) × 100

amount of TPN solution = 9.09 × 100

amount of TPN solution = 909 mL

Therefore, the patient should receive 909 mL of the TPN solution per day.

The translated coordinates of B is B'(97,69).

What is translation?

A translation is a geometric change in Euclidean geometry that involves moving each point in a figure, shape, or space by the same amount in one direction. A translation may alternatively be thought of as moving the origin of the coordinate system or as adding a constant vector to each point.

Given, point B with coordinates (95, 71) is mapped onto B' through a translation by vector (2,-4).

That means, the translation is 2 units right and 4 units down.

A positive number means moving to the right and a negative number means moving to the left.

The number at the second term represents up and down movement. A positive number means moving up, and a negative number means moving down.

So, B (95, 71) → B' (95 + 2, 73 -4)

Therefore, the coordinates of B' is (97, 69).
