Unit rate for 8 hours: $9.00/hr. Unit rate for 6 hours: $9.50/hr. ($72.00/8 = $9.00, $57.00/6 = $9.50)

To find the unit rate, which is the amount earned per hour, you divide the total earnings by the number of hours worked.

For babysitting 8 hours and making $72.00:

Unit rate = Total earnings / Number of hours worked

Unit rate = $72.00 / 8 hours

Unit rate = $9.00 per hour

For babysitting 6 hours and making $57.00:

Unit rate = Total earnings / Number of hours worked

Unit rate = $57.00 / 6 hours

Unit rate = $9.50 per hour

So, the unit rate in dollars per hour for each scenario is:

- $9.00 per hour for babysitting for 8 hours and making $72.00.

- $9.50 per hour for babysitting for 6 hours and making $57.00.

Final answer:

The product in simplest form of −6/11 × 3/4 is −9/22, while −1/4 × (−6/11) gives 3/22. The equation 1/3 × 7/8 = m is used to determine how many dog bowls can be filled from a bucket containing 7/8 gallon of water. It takes 93.33 minutes to repair an 18.3 square feet section of road at a rate of 5.1 minutes per square foot.

Explanation:

1. The product in simplest form of −6/11 × 3/4 is calculated by multiplying the numerators together and the denominators together. So, −6 × 3 = −18 and 11 × 4 = 44. The product is −18/44, which simplifies to −9/22 after dividing both numerator and denominator by 2. Therefore, the correct answer is A. −9/22.

2. The product of −1/4 × (−6/11) is found by multiplying the numerators and the denominators separately. −1 × (−6) = 6 and 4 × 11 = 44. The product is 6/44, which simplifies to 3/22 after dividing both numerator and denominator by 2.

3. The story problem that could be solved using the given equation 1/3 × 7/8 = m involves multiplying fractions to find a final value. In option C, Julia has a bucket that contains 7/8 gallon of water, and wants to know how many dog bowls (each bowl holds 1/3 gallon) she can fill. This requires multiplying the two fractions, making option C the correct answer.

4. To find how many total minutes it will take to repair a section of road covering 18.3 square feet, where each square foot requires 5.1 minutes to repair, we multiply 18.3 by 5.1. The calculation is 18.3 × 5.1 = 93.33 minutes. Therefore, it will take 93.33 minutes to repair the section of road.

a) (x,y) =(x-3, y-2)

Answer:

a) (x,y) → (x - 3, y - 2)  

Step-by-step explanation:

Comparing the pre-image points, r, s and t, to the image points, r', s' and t', we see that the x-coordinates of the image are all 3 less than the x-coordinates of the image:

10-7 = 3; 8-5 = 3; 6-3 = 3

This means the first part of the translation rule will be x-3.

Now comparing the y-coordinates, we see that the y-coordinates of the image are all 2 less than the y-coordinates of the pre-image:

6-4 = 2; 4-2 = 2; 6-4 = 2

This means the second part of the translation rule will be y-2.

This gives us (x, y)→(x-3, y-2).

If two lines are intersected by a transversal, and the alternate interior angles are equal, then the lines are parallel.

Conversely, if two lines are parallel, then the alternate interior angles formed by the transversal are equal.

So, Ray can made the conclusion that l and m are parallel because alternate interior angles are equal since m∠3 = m∠6.

Ray can conclude that lines l and m are parallel because alternate interior angles are equal.

Ray knows that the measure of angle 3 (m∠3) is equal to the measure of angle 6 (m∠6). When two lines are intersected by a transversal (a line that intersects two other lines), and the corresponding angles on either side of the transversal are equal, it is a characteristic of parallel lines.

In this case:

- Angle 3 and angle 6 are corresponding angles because they are on the same side of the transversal and in the same relative position with respect to lines l and m.

- The fact that m∠3 = m∠6 indicates that lines l and m have corresponding angles that are equal.

Therefore, based on the given information that m∠3 = m∠6, Ray can conclude that lines l and m are parallel because alternate interior angles (corresponding angles) are equal, which is a property of parallel lines.

78.5 m^2

78.54 m² is your answer. So to recap, a goat tethered to a stake in the ground with a 5 m rope has 78.54 meters to graze.

We get this answer by putting the information into an equation. We know that a circle has 360° (360 degrees) and so when we see the problem say that the goat can graze 360 degrees around the stake, we instantly know it's talking about a circle. Look at the question, it's asking about the area of the circle. Now we can make an equation to find the area of this circle.

The area of a circle is A = πr²

That's Area = Pi times Radius squared.

We'll use 3.14 as substitute for Pi. The radius was given to us, it is 5 m. Put the information into the formula.

A = 3.14 * 5²

Now we do the order of operations. In the order of operations, we have no parenthesis to work with, but we do have an exponent. So we take 5 to the second power, (5² = 5 * 5) and we update our problem.

A = 3.14 * 25

Now we finish the problem by multiplying 3.14 and 25.

A = 78.54

We're not entirely done. Now we include our units of measurement. In this case, we were using m for meters. When solving for area, the unit is always squared in the final answered. So this would be our final answer:

A = 78.54 m²

I hope I am reading the problem right: The price of a mountain bike increased by 20% in the past year. The value is $150. What was the value of the mountain bike last year?

Let's simplify this. One year, there was this radical mountain bike that used to have an unsaid price, x. That year, that price of x increased by 20% more than it was before, or 120% times the original value. Because of that, it's now $150.

We can equation this.

1.20x = 150

x = 150/1.2

x = 125

The bike, I believe, cost $125 last year. Hope this helps!

Final answer:

To find the value of the mountain bike last year, we can use the concept of percentage increase and decrease.

Explanation:

To find the value of the mountain bike last year, we can use the concept of percentage increase and decrease. If the price of the bike increases by 20%, then the current value is 120% of the previous value.

To find the previous value, we can set up an equation: 120% of the previous value is equal to $150. Mathematically, this can be written as 1.2x = 150, where x is the previous value.

Solving the equation, we divide both sides by 1.2 to isolate x: x = $125. Therefore, the value of the mountain bike last year was $125.

The answer would be 0.002

The answer to 0.45 / 225 = 0.002

Answer:

- The equation is: [tex]\frac{249}{2}=2(x+\frac{17}{4})+2x[/tex]

- The width of the postage stamp is 29 milimeters.

- The length is 33.25 milimeters.

Step-by-step explanation:

1. The length ([tex]y[/tex]) is [tex]4^{\frac{1}{4} }mm=\frac{17}{4}mm[/tex] longer than the width ([tex]x[/tex]):

[tex]y=x+\frac{17}{4}[/tex]

2. The perimeter is [tex]124^{\frac{1}{2}}mm=\frac{249}{2}mm[/tex].

3. The perimeter of a rectangle is:

[tex]Perimeter=2Length+2Width[/tex]

4. Substitute values:

[tex]\frac{249}{2}=2(x+\frac{17}{4})+2x[/tex]

5. Solve for the width [tex]x[/tex]:

[tex]\frac{249}{2}=2x+\frac{34}{4}+2x\\x=\frac{116}{4}\\x=29[/tex]

6. Calculate the length:

[tex]y=x+\frac{17}{4}\\y=29+\frac{17}{4}\\y=33.25[/tex]

The width and length of the postage stamp are calculated by formulating and solving an equation based on the given perimeter and the relationship between the length and width. The width is found to be 29 mm, and the length is 33.25 mm.

The subject of this question is Mathematics and it's related to the concept of the perimeter of a rectangle. If we denote the width of the postage stamp as 'W' (in millimeters), then it's length will be 'W + 4.25' millimeters because it's stated in the problem that the length is 4.25 mm longer than the width.

The perimeter of a rectangle (which is the shape we can assume for a postage stamp) is calculated as follows: Perimeter = 2(Length + Width). Substituting the value for length that we've assigned, we get this equation:

124.5 = 2[(W + 4.25) + W]

Solving this equation step-by-step will lead you to the answer. First, distribute the 2 into the parentheses which gives: 124.5 = 2W + 8.5 + 2W. Combine like terms to simplify: 124.5 = 4W + 8.5. Then, subtract 8.5 from both sides of the equation: 116 = 4W. Lastly, divide by 4 to find 'W': W = 29 mm. Therefore, the width of the postage stamp is 29 mm, and the length is 29 mm + 4.25 mm = 33.25 mm.

Answer:

a-bi

Step-by-step explanation:

If a quadratic equation lx^2+mx+n=0 has one imaginary root as a+bi then the other root is the conjugate of a+bi = a-bi

Because we have l, m and n are real numbers and they are the coefficients.

Sum of roots = a+bi + second root = -m/l

When -m/l is real because the ratio of two real numbers, left side also has to be real.

Since bi is one imaginary term already there other root should have -bi in it so that the sum becomes real.

i.e. other root will be of the form c-bi for some real c.

Now product of roots = (a+bi)(c-bi) = n/l

Since right side is real, left side also must be real.

i.e.imaginary part =0

bi(a-c) =0

Or a =c

i.e. other root c-bi = a-bi

Hence proved.
