Final answer:

Dwight will make $1,575 per week by multiplying his hourly wage of $35 by the 45 hours he works each week.

Explanation:

To calculate how much Dwight will make per week, we need to multiply his hourly wage by the number of hours he works per week. According to the question, Dwight earns $35 per hour and works 45 hours per week.

The calculation is as follows: Hourly wage x Hours per week = Weekly earnings

$35/hour x 45 hours/week = $1,575/week

Therefore, Dwight will make $1,575 per week from his construction job.

She started with 45 and added 5 each month.

Find the table that has Y values that are increased by 5's for every 1 increase in x.

45 + 5 = 50

50+5 = 55

55 + 5 = 60

The correct table is the second one.

Answer:

-2

Step-by-step explanation:

given 2 points on a line (x1, yx) and (x2,y2)

the formula for slope, m  = (y2-y1) / (x2-x1)

in this case,

x1 = 4, y1 = 3, x2 = 2, y2 = 7

Hence,

m  = (7-3) / (2-4) = 4 / -2 = -2

The slope of the line that contains the points (4, 3) and (2, 7) is -2.

To estimate the slope of the line that has the points (4,3) and (2,7)

Slope formula = y₂ - y₁ / x₂ - x₁

From the question, the points given are; (4,3) and (2,7)

So,  x₁ = 4, y₁ = 3, x₂ = 2 and y₂ = 7

Slope of the line = 7 - 3 /  2- 4

   = -2

The slope of the line is -2.

therefore, the correct answer is option D. -2.

Answer:

Part a) [tex]22.95+0.43x \leq 25[/tex]

Part b) The maximum number of candy bars that you can purchase is 4

Part c) The change would be [tex]\$0.33[/tex]

Step-by-step explanation:

Part a) Write an equation representing your shopping experience and use x for the number of candy bars

Let

x -----> the number of candy bars

we know that

The inequality that represent this problem is equal to

[tex]2(3.50)+2(2.75)+10.45+0.43x \leq 25[/tex]

[tex]22.95+0.43x \leq 25[/tex]

Part b) Solve the equation to determine how many candy bars can you purchase?

[tex]22.95+0.43x \leq 25[/tex]

Solve for x

Subtract 22.95 both sides

[tex]0.43x \leq 25-22.95[/tex]

[tex]0.43x \leq 2.05[/tex]

Divide by 0.43 both sides

[tex]x \leq 2.05/0.43[/tex]

[tex]x \leq 4.8[/tex]

The maximum number of candy bars that you can purchase is 4

Part c) How much change would you have left?

If you purchase 4 candy bars

then

[tex]22.95+0.43(4)=\$24.67[/tex]

therefore

[tex]\$25-\$24.67=\$0.33[/tex]

The equation representing the shopping experience is 3.50*2 + 2.75*2 + 10.45 + 0.43x = 25. The maximum number of candy bars you can purchase is 4. You would have $1.05 in change left.

a. The equation representing your shopping experience can be written as: 3.50*2 + 2.75*2 + 10.45 + 0.43x = 25, where x represents the number of candy bars.

b. To determine how many candy bars you can purchase, we need to solve the equation for x. First, combine like terms: 7 + 5.50 + 10.45 + 0.43x = 25. Subtracting 22.95 from both sides gives 0.43x = 2.05. Dividing both sides by 0.43 gives x ≈ 4.77. Since you can't purchase a fraction of a candy bar, the maximum number of candy bars you can buy is 4.

c. To find out how much change you would have left, subtract the total cost of items from your budget. The cost of items is 3.50*2 + 2.75*2 + 10.45 = 23.95. Subtracting this from your budget of $25 gives 25 - 23.95 = $1.05 in change.

To simplify the expression x/4x + x^2, we combine like terms and factor out a common factor.and This simplified expression cannot be reduced further.

To simplify the expression x/4x + x^2, we need to combine like terms. First, let's simplify the fraction by finding a common denominator. The common denominator for 4x and x is 4x. Therefore, the fraction becomes x/(4x) + x^2. Next, let's combine the fractions by adding the numerators and keeping the same denominator. This gives us (x + 4x^2)/(4x). Finally, we factor out the common factor x from the numerator, resulting in x(1 + 4x)/(4x). This simplified expression cannot be reduced further.

Final answer:

The equations are $25 + $0.80x for Express Movers and $35 + $0.60x for Smith & Smith Co.

Solving these equations shows that at 50 miles, both options cost the same.

Explanation:

The Brown family is trying to determine the breakeven point in miles for renting a moving truck from two different companies. Express Movers charges an initial fee of $25 plus $0.80 per mile, while Smith & Smith Co. charges $35 initially and $0.60 per mile. To find when these two options cost the same, we will set up equations and solve for the number of miles.

Let's define x as the number of miles driven. The totals cost from each company can be expressed as:

Express Movers: $25 + $0.80x

Smith & Smith Co.: $35 + $0.60x

To find the breakeven point, we equate the two expressions:

$25 + $0.80x = $35 + $0.60x

Now we solve for x by subtracting $0.60x from both sides and then subtracting $25 from both sides to isolate the variable:

$0.20x = $10

Dividing both sides by $0.20 gives us:

x = 50 miles

Therefore, at 50 miles, the cost of renting a truck from Express Movers or Smith & Smith Co. would be the same.

Answer:

444 (gets to 62,666)

Step-by-step explanation:

The closest you can think of first is 63,333. However, as long as there doesn't have to be the four numbers in a row, the "6" in the number can be one of the four same numbers.

This means that you need to get 3 other sixes in the number. There are many ways to do this, but the one requiring the least amount of driving is changing the last three digits (222). If you add 444 to the number, the amount of miles driven is 62,666, there being 4 sixes in the number. This is the least amount of driving needed before the odometer shows four of the five digits the same as each other.

444 is the least number that shows four out of the five digits same.

An odometer is an instrument for measuring the distance travelled by a wheeled vehicle.

Given that,

Total distance covered by Mr. Jackson = 62,222 miles,

The four digits of number 62,222 are same and are 2,

Again, odometer will show four out of 5 digit same, when there will be at least four times 6,

So add 444 in the 62,222

The number = 62,222 + 444 = 62,666

So the least number that can be added to make 4 digit same is 444.

The answer is:

The solutions to the system of equations are:

[tex]x=0\\y=1\\z=0[/tex]

To solve the system of equations by the easiest way, we need to use the reduction method. The reduction method consist of reducing the variables applying different math operations in order to be able to isolate the variables.

So, we are given the system:

[tex]4x+3y+6z=3\\5x+5y+6z=5\\6x+3y+6z=3[/tex]

Let's work with the first and the third equation:

[tex]4x+3y+6z=3\\6x+3y+6z=3[/tex]

Then, multiplying the first equation by -1, we have:

[tex]-4x-3y-6z=-3\\6x+3y+6z=3[/tex]

[tex]-4x+6x-3y+3y-6z+6z=-3+3[/tex]

[tex]2x=0[/tex]

[tex]x=0[/tex]

Now, working with the first and the second equation, we have:

[tex]4x+3y+6z=3\\5x+5y+6z=5[/tex]

Then, multiplying the first equation by -1, we have:

[tex]-4x-3y-6z=-3\\5x+5y+6z=5[/tex]

[tex]5x-4x+5y-3y-6z+6z=-3+5[/tex]

[tex]x+2y=2[/tex]

Then, substituting "x" into the equation, we have:

[tex]0+2y=2[/tex]

[tex]y=\frac{2}{2}=1[/tex]

Finally, working with the first equation and substituting "x" and "y", we have:

[tex]4x+3y+6z=3[/tex]

[tex]4*0+3*1+6z=3[/tex]

[tex]0+3+6z=3[/tex]

[tex]6z=3-3=0[/tex]

[tex]6z=0[/tex]

[tex]z=\frac{0}{6}=0[/tex]

Hence, we have that the solutions to the system of equations are:

[tex]x=0\\y=1\\z=0[/tex]

Have a nice day!

Answer:

Step-by-step explanation:

Multiply the first equation by -1:

[tex](-1)(4x+3y+6z)=3(-1)\\\\-4x-3y-6z=-3[/tex]

Add the new equation and the third equation an solve for "x":

[tex]\left \{ {{-4x-3y-6z=-3\ \atop {6x+3y+6z=3} \right.\\...........................\\2x=0\\x=0[/tex]

Substitute the value of "x" into the first equation and solve for "y":

[tex]4(0)+3y+6z=3\\\\3y=3-6z\\\\y=\frac{3-6z}{3}\\\\y=1-2z[/tex]

Substitute the value of "x" and [tex]y=1-2z[/tex] into the second equation and solve for "z":

Answer:

A = 47° and B = 43°

Step-by-step explanation:

Express angle A in terms of angle B, that is

A = B + 4

Complementary angles sum to 90°, hence

A + B = 90, that is

B + 4 + B = 90

2B + 4 = 90 ( subtract 4 from both sides )

2B = 86 ( divide both sides by 2 )

B = 43

Hence

∠B = 43° and ∠A = B + 4 = 43 + 4 = 47°

Answer:

A= 47°

B= 43°

Explanation:

A complementary angle is a 90° angle.

If A+B= 90 and B+4= A, we can rewrite it as...

B+4+B= 90

→ 2B+4= 90

→ 2B= 86

→ B= 43

Then we go back to the equation A+B= 90 and plug in B as 43...

A+43= 90

→ A= 47

Answer: 8

Step-by-step explanation: We are dealing with a 30 60 90 triangle which has special side lengths that I will attach.

The short leg, in this case 4, is half of the hypotenuse in 30 60 90 triangles, therefore x = 8

You need to remember the following identity:

[tex]sin\alpha=\frac{opposite}{hypotenuse}[/tex]

In this case, we can observe that:

[tex]\alpha=30\°\\opposite=4\\hypotenuse=x[/tex]

Now you must substitute these values into  [tex]sin\alpha=\frac{opposite}{hypotenuse}[/tex] and solve for the hypotenuse. Then:

[tex]sin(30\°)=\frac{4}{x}\\\\(x)(sin(30\°))=4\\\\x=\frac{4}{sin(30\°)}\\\\x=8[/tex]

The length of the given rectangle is 3 yd and the width is 3.66 yd.

A rectangle is a type of parallelogram having equal diagonals.

All the interior angles of a rectangle are equal to the right angle.

The diagonals of a rectangle do not bisect each other.

Given that,

The area of rectangle is 42 square yd.

Suppose the width of the rectangle is x yd.

Then its length is given by 3x - 11 yd.

As per the problem, the following equation can be formed,

x(3x - 11) = 42

Solve the above equation for x as,

x(3x - 11) = 42

=> 3x² - 11x = 42

=> 3x² - 11x - 42 = 0

=> x = -1, 4.66

Since, the width cannot be negative. The value of x is taken as 4.66.

Thus, the length is is given by 3 × 4.66 - 11 = 3.

Hence, the length and width of the rectangle are 3yd and 4.66yd respectively.

Answer:

The height is 6.

Step-by-step explanation:

To find the answer, identify the dimensions you have and what you to find. We have the area (144) and base (24) and we need to find the height. To find the height, you must divide area by the base (it's really simple).

Ex.

[tex]144 / 24 = ?\\144 / 24 = 6[/tex]

The quotient you found is the height. Therefore, the answer is 6.

Final answer:

To find the height of a parallelogram with an area of 144 cm² and a base of 24 cm, divide the area by the base to obtain the height of 6 cm.

Explanation:

Mathematics:

To find the height of a parallelogram, you can use the formula Area = base * height. In this case, the area is given as 144 cm² and the base is 24 cm. Substituting these values into the formula, we get 144 = 24 * height. To find the height, divide both sides of the equation by 24: height = 144/24 = 6 cm. Therefore, the height of the parallelogram is 6 centimeters.
