Answer:

Julie worked 18 hours at Job A and 17 hours at Job B.

Step-by-step explanation:

1. Let's review the data given to us for solving the question:

Rate per hour at Job A = US$ 6.10

Rate per hour at Job B = US$$ 7.40

Hours at Job A = x

Hours at Job B = 35 - x

Total of hours worked by Julie = 35 hours

Total weekly earnings = US$ 235.60

2. How many hours did she work at each job the week that she made $235.60?

For finding the result, we will use the following formula:

6.10x + 7.4 (35 - x) = 235.60

6.10x + 259 - 7.4x = 235.60

-1.3x = 235.60 - 259 (Subtracting 259 to both sides)

-1.3x = - 23.40

x = -23.4/-1.3 (Dividing by -1.3)

x = 18

Julie worked 18 hours at Job A, so she worked 17 (35 - 18) hours at Job B.

3. Proof that x = 18 is correct.

6.10x + 7.4 (35 - x) = 235.60

6.10 (18) + 7.4 (35 - 18) = 235.60

109.80 + 125.80 = 235.60

235.60 = 235.60

It's proven that x = 18 is correct.

Answer:

Step-by-step explanation:

Let x represent the number of hours worked at Job A and 35-x represent the number of hours worked at Job B.

($6.10 × x) +$7.40 × (35-x) =$235.60

Solving for x

$6.10x + $259 - $7.40x = $235.60

Collect like terms and solve for x

$6.10x-$7.40x=$235.60-$259

-$1.3x=-$23.4

x=18hours for Job A while 35-x=17hours for Job B

Answer:

5 centimeters of snow per hour.

Step-by-step explanation:

We are given an equation d = 5h, where d = depth of snow and h = hours of the snowstorm.

We need to find the number of centimeters of snow that accumulate in 1 hour.

In order to find the number of hours that accumulate the  snow to 1 centimeter, we need to plug d=1 in the given equation.

On plugging d=1, we get

1= 5h.

Dividing both sides by 5, we get

1/5 = h.

Therefore, it would take 1 hour for 5 centimeters of snow to accumulate in Harper's yard.

The amount of snow accumulation per hour varies, ranging from 0.5 cm in light snow to up to 5 cm in heavy snowfall. However, actual snow accumulation can be influenced by various factors such as temperature, wind speed, and humidity.

The amount of snow accumulation per hour can vary greatly depending on the intensity of the snowfall. For example, a light snowfall might result in as little as 0.5 cm of snow per hour while a heavy snowfall could accumulate up to 5 cm of snow per hour. However, it's important to note that these are just average estimates and actual snow accumulation can be influenced by various factors such as temperature, wind speed, and humidity.

Answer:

10,000 cups

Step-by-step explanation:

Direct proportional quantities are such that their quotients are always the same number. Example: If I need one cup of sugar to prepare 5 candies, I will need 2 cups of sugar to prepare 10 candies. The quotient 5/1 is equal to the quotient 10/2

Let's suppose a cup of regular ice cream would have 100 parts of fat.

The brand of ice cream mentioned in the question is 99% fat-free which means for every cup of their ice cream, we'll only get 1 part of fat. The relation is 100/1.

If we wanted 100 parts of fat out of fat-free ice cream we would need 100*100/1=10,000 cups of it

These numbers won't change if we used another number instead of 100 in the example shown.

Answer:

1/12

Step-by-step explanation:

You want to find the compatible numbers with the common denominator so you want to multiply by ones until you get something with the same denominator. In this case it's 12, 1/3 x 4 = 4/12 and 1/4 x 3 = 3/12, Then subtract. Therefore you get your answer 1/12

George ate 1/12 of the pan of brownies.

There are 1/3 pan of brownies. George eats 1/4 of this pan.

In order to find out the fraction of the brownie pan that George ate, you need to multiply the proportion of the pan that still has brownies with the proportion that George ate.

The total fraction of the pan he ate is:

= Amount of pie George has x Amount of brownies he eats

= 1/3 x 1/4

= 1/12 of the pan

This means that out of the whole pan of brownies, George ate 1/12.

Answer:

3 7/12

Step-by-step explanation:

first you have to make both denominators the same through multiplication but remember if you do that you have to multiply the numerator by the same number as the denominator. then after you do that you can add them and if it comes out improper then you need to simplify your fraction and you have the answer.

Answer: 3⁷/₁₂

Explanation:

Numerator- number on top of fraction

Denominator- number on bottom of fraction

First find a common denominator. A number that both denominators can go into. In this case we'll use 12. Because both of the denominators, 6 and 4, fit into 12.

6 goes into 12 twice. And 4 goes into 12 three times.

To convert to a common denominator, multiply both the numerator and the denominator by the same number. Do not multiply the whole number.

So because 6 goes into 12 twice, we multiply by 2.

⁵/₆ x 2 = ¹⁰/₁₂

And because 4 goes into 12 three times, we multiply by 3.

2³/₄ × 3 = 2⁹/₁₂

Okay so now that both numbers have a common denominator, we can add.

¹⁰/₁₂ + 2⁹/₁₂ = 2 ¹⁹/₁₂

Simplified as 3 ⁷/₁₂

(a) D(c) = f + cx    

(b) Delivery fee is $5.

(c) The cost per calendar is $19.

Step-by-step explanation:

Let,

Delivery fee = f

Cost of calendar = x

No. of calendars = c

Total cost with delivery fee = D

Therefore,

The cost of 2 calendars plus delivery fee is $43.

D(c)= f + cx

43 = f + 2x Eqn 1

The cost of 4 calendars plus delivery is $81.

D(c) = f + cx

81 = f +4x    Eqn 2

(a)Write an equation that gives the  total cost as a function of calendars bought.

D(c) = f + cx      

(b)What is the delivery fee?

Multiplying Eqn 1 by 2;

[tex]2(43 = f + 2x)\\86=2f+4x\ \ \ Eqn\ 3[/tex]  

Subtracting Eqn 2 from Eqn 3;

[tex](2f+4x)-(f+4x)=86-81\\2f+4x-f-4x=5\\f=5[/tex]

Delivery fee is $5.

(C)What is  the cost per calendar?

Putting f=5 in Eqn 1;

[tex]43=5+2c\\43-5=2c\\2c=38\\[/tex]

Dividing both sides by 2

[tex]\frac{2c}{2}=\frac{38}{2}\\c=19[/tex]

The cost per calendar is $19.

730.36

Step-by-step explanation:

.24 × 589= 141.36

141.36+589=730.36

so the original price would be 730.36

The points located 5 units from the point M (-6, 6) are (-1, 6), (-11, 6), (-6, 11) and (-6, 1).

To find a point located 5 units from point M in any direction, you can use the coordinates of point M and adjust them based on the distance.

If point M is located at (-6, 6), and you want a point 5 units away, you can choose a direction (left, right, up, or down) and adjust the coordinates accordingly.

For example, if you want a point 5 units to the right of M, you add 5 to the x-coordinate:

[tex]x_{new[/tex] = -6 + 5 = -1

So, a point located 5 units to the right of M is (-1, 6).

If you want a point 5 units to the left of M, you subtract 5 from the x-coordinate:

[tex]x_{new[/tex] = -6 - 5 = -11

So, a point located 5 units to the left of M is (-11, 6).

Similarly, the y-coordinate can be modified for points 5 units above or below M.

For example, if you want a point 5 units to the top of M, you add 5 to the y-coordinate:

[tex]y_{new[/tex] = 6 + 5 = 11

So, a point located 5 units to the top of M is (-6, 11).

If you want a point 5 units to the bottom of M, you subtract 5 from the y-coordinate:

[tex]y_{new[/tex] = 6 - 5 = 1

So, a point located 5 units to the bottom of M is (-6, 1).

Answer:

Ratio of PQC to ABC is 2:9.

Step-by-step explanation:

In ΔBRQ and ΔBPC

∠BQR = ∠BCP (given) and ∠B is common for both triangles, so from AAA similarity ΔBRQ and ΔBPC are similar.

⇒ BQ : QC = BR : RP = 2 : 1    →(1)

now draw perpendiculars from points A and P to BC line segment. Call the projected points as A' and P'.

It is clear that lines AA' and PP' are parallel. So in ΔBPP' and ΔBAA' we have AAA similarity with common angle at B.

⇒PP' : AA' = BP : BA = 2 : 3    →(2) (∵ AP : PB = 1 : 2)

area of ΔPQC = 0.5×PP'×QC

area of ΔABC = 0.5×AA'×BC

area of ΔPQC : area of ΔABC = (0.5×PP'×QC)/(0.5×AA'×BC)

                                               =(PP'/AA')×(QC/BC)

                                               =(2/3)×(1/3) (∵ from (1) and (2))

                                               =2/9.
