Length of each Plan B workout is: 1.25 hours

How to Solve a System of Linear Equations?

The number of hours that each of the workout plans last can be represented as a system of linear equations. The explanation below shows how to solve this problem using the elimination method.

Let,

x = number of hours for each plan A workout.

y = number of hours for each plan B workout.

Create the system of equations below:

Equation for Friday would be:

3x + 2y = 4 --> equation 1

Equation for Saturday would be:

8x + 4y = 9 --> equation 2

Multiply equation 1 by 4 and equation 2 by 2:

12x + 8y = 16 --> eqn. 3

16x + 8y = 18 --> eqn. 4

Substract eqn. 4 from eqn. 3:

-4x = -2

x = 1/2 = 0.5 [0.5 hours or 1/2 an hour for Plan A]

Substitute x = 0.5 into eqn.1:

3(0.5) + 2y = 4

1.5 + 2y = 4

2y = 4 - 1.5

2y = 2.5

y = 2.5/2

y = 1.25 [1.25 hours for Plan B]

The measure of an angle and it’s complement differ by 22 degrees. Find the larger angle.

Answers

The measure of an angle and its complement differ by 22 degrees and the larger is 56°

What are  Complementary Angles?

The total of the two angles' measurements determines their complement and supplement. The pair of angles is said to be complimentary if the product of the two angles equals the measurement of a right angle.

1. If the total of two angles equals 90°, the angles are considered to be complements of one another.

2. Let x° and y° be the two angles. Since they complement one another, the two angles' sum will be 90 degrees.

= x + y = 90°. (Assume equation 1 is used.)

3. The two angles differ by 22 degrees, hence the equation will be,

= x - y = 22°. (Put equation 2 in.

4. To determine the values of x and y, solve equations 1 and 2.

Add equations 1 and 2 together.

= x + y + x - y = 90 + 22,

= 2x = 112°,

= x = 56°.

5. In equation 1, change the value of x.

= 56° + y = 90°,

= y = 90 -56,

= y = 34°.

So, the measure of the two angles is 56°, and 34°.

And the larger angle is  56°

Last year, Kaitlyn had $30,000 to invest. She invested some of it in an account that paid 5% simple interest per year, and she invested the rest in an account that paid 9% simple interest per year. After one year, she received a total of $2580 in interest. How much did she invest in each account?First account:Second account:

Answers

Answer:

She invested an amount of $3,000 in the first accont and $27,000 in the second account

Explanation:

Here, we want to get the amount invested in each of the accounts

To get this,let us write the simple interest formula

Mathematically, we have this as:

[tex]I\text{ = }\frac{PRT}{100}[/tex]

Let the amount invested in the first account be $x, while that of the second account be $y

P represent the amounts invested

R is the rate of investment

T is the time (1 year)

The sum of these two is the $30000 she has to invest

Mathematically, we have this as:

[tex]x\text{ + y = 30000}[/tex]

Let us get the interests on each of the accounts

For the first account, we have the interest as:

[tex]I_1\text{ = }\frac{x\times5\times1}{100}\text{ = }\frac{5x}{100}[/tex]

For the second account, we have the interest as:

[tex]I_2\text{ = }\frac{y\times9\times1}{100}\text{ =}\frac{9y}{100}[/tex]

The sum of these two is the interest value, which is as follows:

[tex]\begin{gathered} I_1+I_2\text{ = }\frac{5x}{100}+\frac{9y}{100}\text{ = 2580} \\ \\ 5x\text{ + 9y = 258000} \end{gathered}[/tex]

So, we have two equations to solve simultaneously

The two equations are:

[tex]\begin{gathered} x\text{ + y = 30000} \\ 5x\text{ + 9y = 258000} \end{gathered}[/tex]

We can solve this by substitution

Let us substitute for y

[tex]y\text{ = 30000-x}[/tex]

Insert this into the second equation, we have this as:

[tex]\begin{gathered} 5x\text{ + 9(30000-x) = 258000} \\ 5x\text{ + 270000-9x = 258000} \\ 9x-5x\text{ = 270000-258000} \\ 4x\text{ = 12000} \\ x\text{ = }\frac{12000}{4} \\ x\text{ = 3,000} \end{gathered}[/tex]

Recall:

[tex]y\text{ = 30000-x = 30000-3000 = 27000}[/tex]

What this mean is that:

John saves 2/5 of his take-home pay. After

A. $800

C. $2,000

B. $1,920

D. $3,500

Answers

John's paycheck is $2,000.

According to the question,

We have the following information:

John saves 2/5 of his take-home pay.

After 6 paychecks, he has saved $4,800.

Now, let's take John's paycheck to be $x.

Now, 2/5 of this paycheck will be $2x/5.

So, this is the amount saved from 1 paycheck of John.

Now, to find the amount saved in 6 paychecks will be:

6*(2x/5)

Now, we can equate this to the amount saved by John after 6 paychecks.

6*(2x/5) = $4,800

12x/5 = 4800

12x = (4800*5)

x = (4800*5)/12

Now, dividing 4800 by 12:

x = 400*5

x = $ 2000

Hence, the correct option is C ($2,000).

Given:

m∠A = (4x - 2) degrees

m∠B = (11x + 17) degrees

Let's find the value of x if the angles A and B are complementary angles.

Complementary angles are angles that sum up to 90 degrees.

Hence, we have:

m∠A + m∠B = 90

(4x - 2) + (11x + 17) = 90

Let's solve for x.

• Remove the parentheses:

4x - 2 + 11x + 17 = 90

• Combine like terms:

4x + 11x - 2 + 17 = 90

15x + 15 = 90

• Subtract 15 from both sides:

15x + 15 - 15 = 90 - 15

15x = 75

• Divide both sides of the equation by 15:

[tex]\begin{gathered} \frac{15x}{15}=\frac{75}{15} \\ \\ x=5 \end{gathered}[/tex]

F = temperature in Fahrenheit

C = temperature in Celsius

To convert from Fahrenheit to Celsius, let us make C the subject of formula;

Recall that the volume of the a right circular cone with height h and radius …

Answers

Given:

The change in volume by time is, (dV/dt) = 10 cubic feet per minute.

The diameter and height of the right circular one are equal, 2r = h.

Height of the pile is, h = 21 ft.

The objective is to find the rate of increase in height of the pile.

Explanation:

The general formula of volume of cone is,

[tex]V=\frac{1}{3}\pi r^2h\text{ . . . . . (1)}[/tex]

From the given data, radius of the cone can be calculated as,

[tex]\begin{gathered} 2r=h \\ r=\frac{h}{2} \end{gathered}[/tex]

Substitute the value of r in equation (1).

[tex]\begin{gathered} V=\frac{1}{3}\pi(\frac{h}{2})^2h \\ V=\frac{1}{3}\pi(\frac{h^2}{4})^{}h \\ V=\frac{1}{12}\pi h^3\text{ . . . . . (2)} \end{gathered}[/tex]

To find rate of increase in height of the pile:

Now, differentiate equation (2) with respect to time t.

[tex]\begin{gathered} \frac{dV}{dt}=\frac{\pi}{12}\times\frac{d}{dt}(h^3) \\ \frac{dV}{dt}=\frac{\pi}{12}\times3h^2\frac{dh}{dt} \\ \frac{dV}{dt}=\frac{\pi}{4}\times h^2\frac{dh}{dt}\text{ . . . . (3)} \end{gathered}[/tex]

Substitute (dV/dt) and h in equation (3).

On plugging the obtained values in eqation (3),

[tex]\begin{gathered} 10=\frac{\pi}{4}\times(21)^2\frac{dh}{dt} \\ \frac{dh}{\mathrm{d}t}=\frac{10\times4}{21^2\times\pi} \\ \frac{dh}{dt}=0.02887164\ldots.\text{.} \\ \frac{dh}{dt}\approx0.029\ldots\text{ ft/min} \end{gathered}[/tex]

Which steps should be used to graph the equation y-4 = 1/3 (x + 2)?

Answers

Graph of a function

We have the following equation:

y - 4 = 1/3 (x + 2)

We clear y in order to be more unterstandable:

y - 4 = 1/3 (x + 2)

y = 1/3 (x + 2) + 4

y = 1/3 x + 2/3 + 4

y = 1/3 x + 2/3 + 12/3

y = 1/3 x + 14/3

Step 1

In order to find the answer we are going to determine x value when y = 4:

y = 1/3 x + 14/3

4 = 1/3 x + 14/3

4 - 14/3 = 1/3 x

12 - 14 = x

-2 = x

Then, it passes through the point (-2 , 4), so we can discard options A and B (because it doesn't pass through (2, 4))

Step 2

We know a linear equation is given by:

y = mx + b, where m and b are numbers: m is the slope of the line and b the y-intercept.

In this case y = 1/3 x + 14/3, the slope is 1/3. We know m is given by

m = Δy/Δx

Since in this case

m = 1/3 = Δy/Δx

Then

Δx = 3 and Δy = 1

That means that if it changes 3 units on the x-axis, then it changes 1 unit on the y-axis

In a right-angle triangle, the side opposite the right angle is the Hypotenuse, the side opposite the given angle that is non-right angle is the Opposite and the remaining side is the Adjacent.

So, after noting the three sides in a right triangle, we will then use trignometric ratios to solve for any of the unknown. If the non-right-angle angle given is θ, the trignometric ratios in short forms are written as

SOH, CAH and TOA

SOH means Sin θ = (Opp/Hyp)

CAH means Cos θ = (Adj/Hyp)

TOA means Tan θ = (Opp/Adj)

So, the one to be used depends on the sides of the triangle that are provided.

For this triangle, using the angle 60° as the non-right-angle angle

Hypotenuse = ?

Opposite = 3√2

Adjacent = x

Angle = 60°

TOA means Tan θ = (Opp/Adj)

Tan 60° = (3√2)/x

Tan 60° = √3

Tan 60° = (3√2)/x

√3 = (3√2)/x

x = (3√2)/(√3)

x = (√3) (√2)

Answers

ANSWER:

Regular pay is $383.2

Overtime rate is $14.37

Overtime pay is $114.96

Gross pay is $498.16

STEP-BY-STEP EXPLANATION:

Assuming the overtime multiplier is 1.5 and the standard work week is 40 hours. Therefore, we calculate the regular payment like this:

[tex]RP=40\cdot9.58=383.2[/tex]

The overtime rate would be the value of the normal payment times the overtime multiplier, like this

[tex]OTR=9.58\cdot1.5=14.37[/tex]

Then we multiply the number of additional hours to the 40 hours allowed, that is, 8 (48 - 40), for which one gives overtime pay

[tex]OTP=8\cdot114.96=114.96[/tex]

Now the gross pay would be the sum of the regular payment with the overtime payment:

[tex]GP=114.96+383.2=498.16[/tex]
