Answer:

Mrs. Dryson made 3 groups with 17 glasses of bears each or she made 17 groups with 3 glasses of bears each.

Step-by-step explanation:

Let the number of groups is x and each group gets y number of bears.

Now, Mrs. Dryson distributed 52 glass bears equally in groups and there was 1 bear left over.

Therefore, xy = 52 - 1 = 51

Now, x and y both must be whole numbers.

Now, we have 51 = 3 × 17, which is the only possible factorization of 51.

So, if x = 3 then y = 17 and if x = 17, then y = 3.

Therefore, Mrs. Dryson made 3 groups with 17 glasses of bears each or she made 17 groups with 3 glasses of bears each. (Answer)

Answer: Multiplied by 10

Step-by-step explanation:

To find the common difference (rate or slope) we can divide the 2nd term to the 1st term.

54.2 / 5.42 = 10 (rule)

Since the common difference is the same throughout the sequence, we can name this as a "arithmetic sequence".

We can multiply 10 to 542 to find the 4th term: 542 * 10 = 5,420

Answer:

20 cups

Step-by-step explanation:

15 / 6 = 5/2

8 * 5/2 = 20

20 cups of milk would be required by Brian to prepare 15 dozen brownies. By utilizing ratios and proportions, this conclusion has been obtained.

To solve this problem, we can use both proportions and ratio. Brian uses 8 cups of milk for every 6 dozen (or 72) brownies. This can be written as the ratio 8:72 or the proportion 8/72 = x/180. From the proportion, we know the cross products are equal, so 8*180 = 72*x. Solving for x gives us x = (8*180)/72. Therefore, Brian would need 20 cups of milk to make 15 dozen brownies.

10. 7n - 1 < -8

Isolate the variable, n. Do the opposite of PEMDAS. Treat the < as equal sign, what you do to one side, you do to the other. First, add 1 to both sides:

7n - 1 (+1) < - 8 (+1)

7n < - 8 + 1

7n < - 7

Isolate the variable, n. Divide 7 from both sides:

(7n)/7 < (-7)/7

n < -7/7

n < -1

n < -1 is your answer.

11. 3 > -7v + 4v

Combine like terms, then isolate the variable, v. First, add -7v and 4v together.

3 > (-7v + 4v)

3 > (4v - 7v)

3 > (-3v)

Isolate the variable, v. Divide -3 from both sides. Note that since you are dividing a negative number, you must flip the sign:

(3)/-3 > (-3v)/-3

3/-3 > v

-1 < v

v > -1 is your answer.

(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?

Answer:

I believe it's 35 miles per gallon of gas

Answer:

35 miles per gallon

Step-by-step explanation:

Here we know that the car driven 402.5 miles on 11.5 gallons of gas, so we can write the following equivalence:

402.5 m = 11.5 g

With m being miles and g gallons.

We want to know the equivalent of miles for 1 gallon. So, lets take the equivalence and divide it by 11.5

402.5/11.5 m = 11.5/11.5 g

35 m = 1g

So, each gallon permits to travel 35 miles. If you want to verify it, just multiply 11.5 (the gallons) g by the number of miles, 35:

11.5 * 35 = 402.5

Answer:

97.5 sq. ft.

Step-by-step explanation:

Im presuming the question asks to find area of the shaded region.

First of all, the total figure is a rectangle. We can write an expression(in words) for the shaded area.

Shaded Area = Area of Rectangle - Area of Small Triangle(White) - Area of Large Triangle(White)

Now, we find respective areas.

Area of rectangle:

length * width = (5+10) * (12) = 15 * 12 = 180

Area of Small Triangle (white):

A = (1/2) * base * height = (1/2) * 5 * (12-3) = (1/2) * 5 * 9 = 22.5

Area of Large Triangle (white):

A = (1/2) * base * height = (1/2) * 10 * (12) = 60

Now, we find area of shaded region:

Shaded Area = Area of Rectangle - Area of Small Triangle(White) - Area of Large Triangle(White)

Shaded Area = 180 - 22.5 - 60 = 97.5 sq. ft.

Answer:

97.5 sq. ft.

Step-by-step explanation:

See the given diagram with given measurements.

The area of the shaded portion is to be determined.

Now, we have to first find the area of the two right triangles formed at the left and right sides.

We know that the area of a right triangle = [tex]\frac{1}{2} \times (\textrm {Base})\times (\textrm {Height})[/tex]

Then the area of the left side triangle = [tex]\frac{1}{2} \times 5 \times (12 - 3) = 22.5[/tex] sq. ft.

Now, the are of the right side triangle = [tex]\frac{1}{2} \times 10 \times 12 = 60[/tex] sq. ft.

Now, the area of non-shaded region = Total are of the two right triangles  

= (60 + 22.5) = 82.5 sq. ft.

Therefore, the area of the shaded region is = (Area of the total rectangle - Area of the non-shaded region)

= [(10 + 5) × 12] - 82.5

= 97.5 sq. ft. (Answer)

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

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:

C

Step-by-step explanation:

Two pyramids are similar. It means that their side lengths are proportional.

So, let's see the proportionality constant from SMALL PYRAMID to LARGE PYRAMID.

The corresponding length of 8 in small pyramid is 24 in large pyramid. We ask ourself:  "8 times WHAT gives us 24?"

This is the proportionality constant (aka "k").

So, 8 times "3" is 24. So the proportionality constant is "3".

k = 3

Now, the height of small pyramid is 6 and height of large pyramid is "x". These sides will be same way proportional. So, we can say:

6 times the proportionality constant (3) would give us x

So,

6 * 3 = x

x = 18

Answer:

12:45 pm and 7:30 pm

Step-by-step explanation:

In a 24 hour clock, we don't use pm or am to identify time. But in a 12 hour clock , am or pm is used. Given time is in 24 hour clock.

So, for 12:45, in 12 hour clock it will be 12:45 pm because, when the time crosses 11:59, it becomes pm.

For, 19:30, it will 19:30-12:00= 7:30 pm.

Final answer:

To convert 12:45 from the 24-hour clock to the 12-hour clock, it remains 12:45 AM. To convert 19:30, you subtract 12 hours, making it 7:30 PM because it is after noon.

Explanation:

To convert times from the 24-hour clock to the 12-hour clock, you need to remember that the 24-hour clock runs from 0:00 (midnight) to 23:59, while the 12-hour clock repeats the cycle of AM and PM hours from 1 to 12.

Solution to (a):

12:45 in the 24-hour clock is straightforward. Since it's already in the AM range, it's the same in the 12-hour clock - 12:45 AM.

Solution to (b):

To convert 19:30 from the 24-hour clock to 12-hour clock format, subtract 12 hours from the 24-hour time if it is greater than 12. Thus, 19:30 becomes 7:30 PM because 19 - 12 = 7, and any time past noon is in the PM.
