Answer:

The number of days in y hours is y/24

Step-by-step explanation:

Here, we want to write an expression

Mathematically;

1 day = 24 hours

? days = y hours

? days = (y * 1)/24

? days = y/24

p = 304

Step-by-step explanation:

Given p is inversely proportional to q² then the equation relating them is

p = [tex]\frac{k}{q^{2} }[/tex] ← k is the constant of proportion

To find k use the condition p = 19 when q is 8, then

19 = [tex]\frac{k}{8^{2} }[/tex] =[tex]\frac{k}{64}[/tex]  ( multiply both sides by 64 )

k = 1216

p = [tex]\frac{1216}{q^{2} }[/tex] ← equation of proportion

When q = 2, then

p =  [tex]\frac{1216}{2^{2} }[/tex]=[tex]\frac{1216}{4}[/tex]=304

Answer:

1738.67 feet

Step-by-step explanation:

Imagine a right angles triangle, with the base length of 1800ft and the angle between the base and the hypotenuse to be 15 degrees.

Now, we have to calculate the hypotenuse length, using trigonometric ratios

The ratio that links adjacent side and hypotenuse is cos

So, write an equation:

cos(15) = Adjacent/Hypotenuse  = 1800/H

Rearrange to solve.

H = cos(15) x 1800 = 1738.67

This is the distance flown by the aeroplane .

Calculation. Formula.

P (1 + r/n)^(nt)

Calculate accrued amount. Principal + Interest. A = P(1 + r)t

Calculate principal amount. Solve for P in terms of A. P = A / (1 + r)t

Calculate principal amount. Solve for P in terms of I. ...

Calculate rate of interest. As a decimal. ...

Calculate rate of interest. As a percent. ...

Calculate time. Solve for t.

The solution for P (Principal amount) in a compound interest Formula is; P = A/(1+ r)^t.

By convention, the formula for calculating the compound interest is;

On this note, it follows that; the principal amount, P can be calculated by dividing both sides of the equation by the expression; (1+ r)^t.

Ultimately, the solution for P is; P = A/(1+ r)^t.

Answer:

52

Step-by-step explanation:

Let each of the base angles = x

x + x + 76 = 180                 Subtract 76 from both sides

x + x = 104                         Combine the 2 xs

2x = 104

x = 52

Each base angle has a measure of 52

Michael's take home pay from each job are;

[tex]\begin{array}{cccc}Gross \ Income& Take \ home \ Pay\\\$1,250& \$1,100\\\$1,525 &\$1,342\\\$1,850&\$1,628\\\$2,200&\$1,936\\\\Sum&\$6,006\end{array}\\[/tex]

Step-by-step explanation:

The given parameters are;

The percentage of Michael's income that he estimates will go to his taxes = 12%

The number of jobs Michael has = Four jobs

The table Michael created can be presented and the estimated taxes and the take home pay entered as follows;

Tax owed = Gross income × Tax percent

Take home pay = Gross income - Tax owed

[tex]\begin{array}{cccc}Gross \ Income& Multiplied \ by \ Tax \ Percent &Taxes \ Owed& Take \ home \ Pay\\\$1,250&\times \ 0.12 =&\$150& \$1,100\\\$1,525 &\times \ 0.12 =&\$183&\$1,342\\\$1,850&\times \ 0.12 =&\$222&\$1,628\\\$2,200&\times \ 0.12 =&\$264&\$1,936\\\\Sum&&\$819&\$6,006\end{array}\\[/tex]

Step-by-step explanation:

A) Discriminant = b² - 4ac = (12)² - 4(9)(4) = 144 - 144 = 0

B) Since the discriminant is 0, this means the equation only has one root.

C) The root is real in this case since the discriminant is not negative. Otherwise, we would have two imaginary roots if it were (remember that complex roots come in pairs)

Step-by-step explanation:

The measure of x if the measure of arc DC= 95 degrees is: 47.5.

Based on the diagram, since the angle is half of the arc in order to determine the measure of x will would divide 95 degree by 2 .

Hence:

Measure of x= 95/2

Measure of x= 47.5

Inconclusion the measure of x if the measure of arc DC= 95 degrees is: 47.5.

Answer:

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

A linear function is described by a x term to the power of 1 or even 0. A function when x is to the second power is most usually not a linear function.

In answer A, you have x multiplied against -3x. This will cause an x squared term, so this is not a linear function.

In answer B, you have 1/2 multiplied against x, which is a regular x term subtracted by 2x, causing a regular x term, meaning this function is linear. However, in the small possibility it is not, we will keep going.

In answer C, there is an x squared term so this is not linear.

In answer D, the expression has 1/2x times 2x, which will cause an x squared term.

Thus, the answer is B, which is the only equation without an x squared term.
