Adriel just got hired for a new job and will make $65,000 in his first year. Adriel was told that he can expect to get raises of $5,000 every year going forward. How much money in salary would Adriel make in his 29th year working at this job?

Answer:

B

Step-by-step explanation:

the area (A) of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )

here b = 7 and h = 4 , then

A = [tex]\frac{1}{2}[/tex] × 7 × 4 = [tex]\frac{1}{2}[/tex] × 28 = 14 cm²

Answer:

8x + 2 + 10x - 4 + 38 = 180

18x + 36 = 180

18x = 144, so x = 8

Angle A measures 8(8) + 2 = 64 + 2 = 66°.

Yes, (3, 5) is a solution to this system of equations.

How do you calculate the equation system?

The system has a single solution if the m-values of the two equations differ. The system has no solution if the two equations have the same m-value but distinct b-values.

Substituting x = 3 and y = 5 into the equations, we get:

y = 5 (which is already given)

y = (-5/3)x + 10

y = (-5/3) * 3 + 10

y = -5 + 10

y = 5

Therefore, both equations are satisfied by the point (3, 5), making it a solution to the system of equations.

Yes, (3, 5) is a solution to this system of equations.

The two lines are parallel because they have thesame slope and different y intercept

If two non-vertical lines that are in the same plane has the same slope. However the lines will have different y intercept.

A linear equation is an algebraic equation of the form y=mx+b. involving only a constant and a first-order (linear) term, where m is the slope and b is the y-intercept.

Therefore putting the equations 15x−6y=−5 and 5x−2y=5 into that form.

15x-6y = -5

-6y = -15x-5

y = 5x/2 +5/6

for the second equation,

5x-2y =5

-2y = -5x-5

y = 5x/2 +5/2

therefore , the two lines are parallel because they have the same slope( 5/2) and different y intercept.

Answer:

Therefore, Frank's monthly credit card payment will be $454.31.

Step-by-step explanation:

Monthly payment = (PV * r) / (1 - (1 + r)^-n)

PV = $2,500 + $1,000 + $3,000 + $1,500

= $8,000

r = 0.18 / 12

= 0.015

Monthly payment = ($8,000 * 0.015) / (1 - (1 + 0.015)^-24)

= $454.31

✓ - True If the clerk continues at the same rate, he will meet his goal of 16 transactions in 1 hour.

       ➜ This is true. The clerk is currently going at 6 transactions per 1/3 hours. 6 * 3 = 18, and 18 > 16.

✗ - False At his current rate, the clerk will complete 12 transactions in 1 hour.

       ➜  This is false. As stated above, he will complete 18.

✓ - True At his current rate, the clerk will complete 9 transactions every half hour.

       ➜ Let us set up a proportion to check. Then we will cross-multiply and solve.

[tex]\frac{20\;min}{6} =\frac{30\;min}{x}[/tex]

180 = 20x

x = 9

       ➜ Yes, he will complete 9 every half hour.

✗ - False If the clerk continues at this rate for a 6-hour shift, he will complete 96 transactions.

       ➜  We can utilize a proportion again. 6 hours is equal to 360 minutes. Then, we will cross-multiply and solve.

[tex]\frac{20\;min}{6} =\frac{360\;min}{x}[/tex]

20x = 2,120

x = 106

       ➜ He will complete 106 transactions, not 96. It depends on if they're asking for exactly 96 or at least 96.

The dimensions of the strongest beam are 27 inches x 13.5 inches.

In general, dimension refers to a measurable extent of a physical quantity, such as length, width, height, depth, or time. These dimensions provide a framework for describing and measuring objects and events in the physical world. In geometry, dimension are refers to the number of coordinates needed to specify a point in a space. In physics, the concept of dimension is used to describe the properties of space and time.

We know that the strength of the beam is directly proportional to its width multiplied with the square of its height. Let's call the width of the beam "w" and the height "h". Then we can write the strength of the beam as:

S = kwh², where "k" is the constant of proportionality.

We want to find the dimensions of the strongest beam, which means we want to find the values of "w" and "h" that will maximize the strength "S". To do this, we need to find the maximum value of the function S = kwh² subject to the constraint that the diameter of the log is 18 inches.

The diameter of the log is equal to the width of the beam plus twice the height of the beam:

d = w + 2h

Since the diameter of the log is 18 inches, we can write:

w + 2h = 18

or

w = 18 - 2h

Substituting this expression for "w" into the equation for the strength of the beam, we get:

S = k × w(18-2h) × h²

Expanding and simplifying this expression, we get:

S = 36kh³ - 2kh⁴

To find the maximum value of S, we take the derivative of S with respect to h and set it equal to zero:

dS/dh = 108kh² - 8kh³ = 0

Simplifying this expression, we get:

h²(108 - 8h) = 0

This equation has two solutions: h = 0 and h = 13.5.

Since a beam with height equal to zero would have zero strength, we reject the solution h = 0. Therefore, the maximum strength is achieved when h = 13.5 inches.

To find the corresponding width, we can use the equation we derived earlier:

w = 18 - 2h = 18 - 27 = -9

Since the width of the beam cannot be negative, we reject this solution as well.

Therefore, the required dimensions of the strongest beam are:

Width = 2h = 2(13.5) = 27 inches

Height = h = 13.5 inches

Considering the graph,

The hanger's equation is as follows:

4x= 24

There are 4 numbers here that represent the value of the hanger.

So, x+x+x+x will be 24.

The equation is thus:

4x = 24.

Now, by resolving the equation, we can determine the value of x that balances the hanger:

4x = 24.

When you divide 4 on both sides:

x = 24/4

x = 6.

As a result, the hanger will remain in equilibrium for x = 6.

Answer: So, what are you asking?

Step-by-step explanation:

Since this is about the angle theorem and the angle theorem is a theorem that helps us know the relationship between angles. Being a corresponding angle, x = 105°. Hence option A is correct.

A corresponding angle is an angle that occupies the same relative position as another angle elsewhere in the diagram. The corresponding angle in planar geometry occurs when a transverse line crosses his two straight lines. Two angles correspond or relate to each other by being on the same side of the horizontal line. One is the exterior angle (outside the parallel lines) and the other is the interior angle (inside the parallel lines).

You can see that the transversal line intersects two parallel lines DE and XY. From the transversal theorem of angles in mathematics, we know that when a transversal line intersects two parallel lines, the corresponding angles formed are congruent and therefore equal to each other.

In this question we see that one of the angles is 105°. Therefore x° is congruent to it, x = 105°.

The rate of change of the amount of laundry with respect to the number of loads is a constant value of -1.6 fluid ounces per load.

Any equation that has terms that are either constants or the product of a constant and a variable of the first degree (exponent 1) is said to be linear. In other words, the equation's greatest degree for any variable is 1. One way to express a linear equation is as follows:

ax + b = 0

If an is not equal to zero, a and b are constants, and x is the variable. This is how a linear equation is typically expressed.

The given function is f(x) = 50 - 1.6x.

Now, the rate of change is the slope of the equation.

Comparing the equation with that of the linear equation y = mx + c we see that the slope is -1.6.

Hence, the rate of change of the amount of laundry with respect to the number of loads is a constant value of -1.6 fluid ounces per load.

Answer:

We can use trigonometry to find AB.

First, we can use the fact that the sum of the angles in a triangle is 180° to find angle A:

A + B + C = 180°

A + 90° + 30° = 180°

A = 60°

Now, we can use the sine function to find AB:

sin A = opposite/hypotenuse

sin 60° = AB/96

AB = 96 * sin 60°

AB = 96 * √3/2

AB = 48√3

Therefore, AB is approximately 83.14 cm (rounded to two decimal places).

You rented the car for 10 days.

Let's begin by setting up the equation to solve for the number of days:

Total rental cost = (daily rental cost + CDW fee) x number of days + gasoline cost

We know that the daily rental cost is 37.45, and the CDW fee is 19.40, so we can substitute those values into the equation:

646.50 = (37.45 + 19.40) x number of days + 78

Simplifying the equation:

646.50 = 56.85 x number of days + 78

Subtracting 78 from both sides:

568.50 = 56.85 x number of days

Dividing both sides by 56.85:
