Answer: Waffles: Total Number of Students is 21:56. Simplified it would be 3:8.

Step-by-step explanation:

First, you take the total number of students, which in this case is 56, and subtract it from the number of students who want the pancakes. The difference is 21. That is the number of students who want waffles.

The ratio is 21:56. It must be in that order. It is not the Total number of students: waffles, it is waffles: total number of students.

If it must be simplified, find the greatest common factor. In this problem, it is 7. So the simplified version is 3:8.

Reena's original speed as compared to her new speed concludes that Reena arrived at her destination in her planned amount of time which is 20 hours.

What is speed?

The distance travelled in relation to the time it took to travel that distance is how speed is defined. Since speed simply has a direction and no magnitude, it is a scalar quantity.

Reena's original plan was to drive for 20 hours at an average speed of 50 mph, which means that she would have covered a distance of -

Distance = Speed x Time

Distance = 50 mph x 20 hours

Distance = 1000 miles

Now calculate the distance that Reena actually traveled.

She drove at an average speed of 60 mph for the first 5 hours, covering a distance of -

Distance1 = Speed1 x Time1

Distance1 = 60 mph x 5 hours

Distance1 = 300 miles

For the remaining 15 hours of the journey, she drove at an average speed of 50 mph, covering a distance of -

Distance2 = Speed2 x Time2

Distance2 = 50 mph x 15 hours

Distance2 = 750 miles

The total distance that Reena traveled is the sum of the two distances -

Total Distance = Distance1 + Distance2

Total Distance = 300 miles + 750 miles

Total Distance = 1050 miles

Reena actually traveled 1050 miles to reach Chicago, which is 50 miles more than her planned distance of 1000 miles.

To calculate how much earlier Reena arrived in Chicago than she originally planned, we need to compare the time it took her to travel the two distances -

Time1 = Distance1 / Speed1

Time1 = 300 miles / 60 mph

Time1 = 5 hours

Time2 = Distance2 / Speed2

Time2 = 750 miles / 50 mph

Time2 = 15 hours

Total Time = Time1 + Time2

Total Time = 5 hours + 15 hours

Total Time = 20 hours

Reena arrived in Chicago in 20 hours, which was exactly the same as her original plan.

Therefore, she did not arrive earlier than planned.

Step-by-step explanation:

We know that a cube has 8 corners. So that's 8 cubes just for the corners. We also know that a cube has 12 edges. An edge can be calculated by subtracting 2 from the side length. Since the side length is 7 cubes long, the edge length is 5 cubes long. The total number of cubes is:

N = (number of corner * cubes per corner) + (number of edges * cubes per edges)

[tex]N = (8 * 1) + (12 * 5) = 8 + 60 = 68[/tex]

Rounding to the nearest square unit, the area is approximately 21 square units.

A quadrilateral is a polygon with four sides, four vertices (corners), and four angles. Some examples of quadrilaterals include rectangles, squares, parallelograms, trapezoids, and rhombuses. Quadrilaterals can have sides and angles of different lengths and sizes. However, the sum of the angles in a quadrilateral always adds up to 360 degrees. Quadrilaterals are commonly studied in geometry, where their properties and characteristics are analyzed and used to solve various problems related to area, perimeter, and other geometric concepts.

Here,

To find the area of the figure ABCE, we need to find the height of the triangle ABCE with respect to base AB.

Let's call the point where the height meets base AB as D. Since angle E is 65 degrees, we know that angle AED is 180 - 65 = 115 degrees (since the sum of the angles in triangle AED is 180 degrees).

We also know that angle ADB is a right angle (since AD is perpendicular to AB), so angle EDB is 180 - 115 - 90 = 25 degrees.

Using trigonometry, we can find that the length of AD is:

AD = AB * sin(25) = 10 * sin(25) ≈ 4.24 units.

Therefore, the area of quadrilateral ABCE is:

Area = (1/2) * base * height = (1/2) * AB * AD ≈ (1/2) * 10 * 4.24 ≈ 21.2 square units.

CJ's rectangular prism will require more material to construct since it has a larger surface area than Torey's prism.

To compare the amount of material required to construct the two rectangular prisms, we need to calculate the surface area of each prism. The surface area of a rectangular prism is given by the formula:

Surface area = 2lw + 2lh + 2wh

where l, w, and h are the length, width, and height of the rectangular prism.

For CJ's prism, we have:

l = 7 cm, w = 4 cm, h = 12 cm

So the surface area of CJ's prism is:

Surface area of CJ's prism = 2(7 cm x 4 cm) + 2(7 cm x 12 cm) + 2(4 cm x 12 cm)

= 56 cm² + 168 cm² + 96 cm²

= 320 cm²

For Torey's prism, we have:

l = 10 cm, w = 6 cm, h = 3 cm

So the surface area of Torey's prism is = 2(10 cm x 6 cm) + 2(10 cm x 3 cm) + 2(6 cm x 3 cm)

= 120 cm² + 60 cm² + 36 cm²

= 216 cm²

Therefore, CJ's rectangular prism will require more material to construct since it has a larger surface area than Torey's prism.

The probability of getting at least one head in two flips of a coin is 3/4 or 0.75, which means that there is a 75% chance of getting at least one head in two flips of a coin.

To find the probability of at least one head in two flips of a coin, we can use the complement rule. The complement of the event "at least one head" is "no heads."

The probability of getting no heads in two flips of a coin is (1/2) x (1/2) = 1/4.

Therefore, the probability of getting at least one head in two flips of a coin is:

1 - (probability of no heads) = 1 - 1/4 = 3/4

The probability of getting at least one head in two flips of a coin is 3/4 or 0.75, which means that there is a 75% chance of getting at least one head in two flips of a coin.

a) The probability of finding oil is 0.70, or 70%.

b) The new probability of finding oil is the sum of the probabilities of finding high-quality oil and medium-quality oil, which is  1.00 or 100% .

(a) The probability of finding oil is the sum of the probabilities of finding high-quality oil and medium-quality oil, since both of these outcomes are considered positive for the oil company:

P(find oil) = P(high-quality oil) + P(medium-quality oil) = 0.50 + 0.20 = 0.70

Therefore, the probability of finding oil is 0.70, or 70%.

(b) To interpret the soil test, we can use Bayes' theorem:

P(Ai | S) = P(S | Ai) * P(Ai) / P(S)

where P(Ai | S) is the updated probability of finding oil given the soil test, P(S | Ai) is the probability of observing the soil test result given that there is oil of the corresponding quality, P(Ai) is the prior probability of finding oil of the corresponding quality, and P(S) is the probability of observing the soil test result regardless of the presence of oil.

Using the given probabilities, we can calculate:

P(S) = P(high-quality oil) * P(S | high-quality oil) + P(medium-quality oil) * P(S | medium-quality oil) + P(no oil) * P(S | no oil)

= 0.50 * 0.20 + 0.20 * 0.80 + 0.30 * 0.20

= 0.26

Now we can calculate the updated probabilities for each quality of oil:

P(high-quality oil | S) = P(S | high-quality oil) * P(high-quality oil) / P(S)

= 0.20 * 0.50 / 0.26

= 0.3846 or 0.38 (rounded to two decimal places)

P(medium-quality oil | S) = P(S | medium-quality oil) * P(medium-quality oil) / P(S)

= 0.80 * 0.20 / 0.26

= 0.6154 or 0.62 (rounded to two decimal places)

P(no oil | S) = P(S | no oil) * P(no oil) / P(S)

= 0.20 * 0.30 / 0.26

= 0.2308 or 0.23 (rounded to two decimal places)

The oil company should interpret the soil test as providing evidence for the presence of medium-quality oil, since the updated probability for this outcome is higher than the updated probability for high-quality oil. The revised probabilities for finding oil are:

P(find high-quality oil | S) = P(high-quality oil | S) = 0.38

P(find medium-quality oil | S) = P(medium-quality oil | S) = 0.62

P(find no oil | S) = P(no oil | S) = 0.23

Therefore, the new probability of finding oil is the sum of the probabilities of finding high-quality oil and medium-quality oil, which is:

P(find oil | S) = P(find high-quality oil | S) + P(find medium-quality oil | S)

= 0.38 + 0.62

= 1.00 or 100% (rounded to two decimal places)

The greatest common factor (GCF) of 42, 126, and 210 is 42.

To find the GCF, you can use several methods such as prime factorization or the Euclidean algorithm. One way to find the GCF using prime factorization is to express each number as a product of its prime factors:

42 = 2 × 3 × 7

126 = 2 × 3² × 7

210 = 2 × 3 × 5 × 7

Then, identify the common prime factors and their smallest exponent across all three numbers. In this case, the common prime factors are 2, 3, and 7. The smallest exponent of 2 is 1, the smallest exponent of 3 is 1, and the smallest exponent of 7 is 1. Therefore, the GCF is
