Precalculus Homework help please.

To find how many small cubes can fit inside a larger cube, you need to find the volume of both.

Once you have the volumes, divide the volume of the larger cube, by the volume of the smaller cube.

Volume = L x W x H

Small cube: Volume = 3/4 x 3/4 x 3/4 = 0.421875 cm^3

Large cube: Volume = 3 x 3 x 2 = 18 cm^3

Number of small cubes that can fit: 18 / 0.421875 = 42.67 Cubes.

Since you can't have a partial cube ( 0.67) round down to a whole number:

That means you can fit 42 cubes.

To fill the rectangular box with cubes, Ricky can use 144 larger cubes and 0 smaller cubes, resulting in the least number of smaller cubes being 0. The correct answer is option A) 32.

To find the least number of smaller cubes that Ricky can use to fill the rectangular box, we first need to calculate the volume of the box. The volume of the box can be found by multiplying its length, width, and height. In this case, the volume is 8 inches x 4 inches x 4.5 inches = 144 cubic inches.

The larger cubes have a volume of 1 cubic inch, while the smaller cubes have a volume of 1/8 cubic inch. To minimize the number of cubes used, we want to use the larger cubes as much as possible.

We can now calculate the number of larger cubes that can fit in the box. 144 cubic inches / 1 cubic inch = 144 cubes.

Next, we need to fill any remaining space with the smaller cubes. The remaining space can be calculated by subtracting the volume occupied by the larger cubes from the total volume of the box. 144 cubic inches - 144 cubic inches = 0 cubic inches.

Since there is no remaining space, we do not need to use any smaller cubes. Therefore, the least number of smaller cubes that Ricky can use is 0.

So, the correct answer is option A) 32.

The student's question pertains to a survey on students' opinions about a new school mascot. The survey results showed varying levels of support and opposition, which are crucial for decision-making in educational policy. This demonstrates the real-world application of mathematics in understanding public opinion through statistics.

The student's question deals with a survey conducted by student government members to understand the school community's stance on the new school mascot. This survey follows a systematic sampling method by asking every 15th student entering the school. The outcome showed that 57% oppose, 37% are in favor, and 6% have no opinion regarding the new mascot. Such a poll is useful for making decisions related to public policy and ensuring that actions consider community preferences.

Another key component is understanding the methodology behind this survey. If we consider a similar scenario where 600 students are surveyed with 480 opposing new legislation (as mentioned in one of the examples), we could calculate the percentage opposing the legislation and use this to propose actions or influence decision-making processes regarding school policies.

In the context of educational institutions, conducting polls or surveys is a practical way to involve student bodies in decision-making processes, reflecting a democratic practice in school governance. This kind of statistical analysis forms a crucial part of mathematics in the real world, particularly within the fields of statistics and probability.

Answer:

maybe 2 and a half cups of lemon juice and 7 cups of water

Step-by-step explanation:

hopes this helps :) oof

Answer:

They both get 2 and 1/2 of a cookie!

Hope this helped, God bless you!

Final answer:

Two friends sharing 5 cookies equally will each get 2.5 cookies after dividing the total number of cookies by the number of friends.

Explanation:

If two friends equally share 5 cookies, each friend gets 2.5 cookies. Since cookies typically cannot be equally divided by 2 without cutting them into pieces, we assume here that it's possible to split the cookies such that each person gets an equal share. Here's the calculation:

Start with the total number of cookies, which is 5.

Divide that number by 2, because there are 2 friends sharing the cookies.

The answer is 2.5 cookies for each friend.

This question involves simple division and is an example of how to apply fair sharing in a real-world scenario.

i believe the answer is c. 1/12

hope this helped! have a good day!

The required probability is 1/12 that the first spinner will land on 7 and the second spinner will land on C.

Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.

The probability that the first spinner will land on 7

P(7) = favorable outcomes / total outcomes

P(7) = 1/4

The probability that the second spinner will land on C

P(C) = 1/3

As per the given question, the required probability will be as:

⇒ P(7) × P(C)

⇒ 1/4 × 1/3

⇒ 1/12

Hence, the correct answer would be an option (C).

Step-by-step explanation:

Hopefully that's right. It's a bit hard to see separation

The interquartile range of Harry's collected data set is 1.25 hours.

To calculate the interquartile range (IQR) for the given data set, we must first arrange the data in ascending order, which is already done in this case. The data set is .5, .5, .75, .75, .75, 1, 1, 1, 1, 1.5, 1.5, 2, 2, 3, 4. The next step is to find the medians of the lower and upper halves of the data set to locate the first quartile (Q1) and the third quartile (Q3).

Since the data set has 15 numbers, the median (which is also Q2) would be the 8th value, which is 1.

For Q1, we take the lower half, which consists of the first 7 numbers. The median of this subset is the fourth value: 0.75.

For Q3, we consider the upper half, which consists of the last 7 numbers. The median of this subset is the fourth value: 2.

Now, calculate the IQR by subtracting Q1 from Q3: IQR = Q3 - Q1 = 2 - 0.75 = 1.25.

Therefore, the interquartile range of the data set that Harry collected is 1.25 hours.

4x+12=x^2+5x+6

0=x^2+5x-4x+6-12

0=x^2+x-6

0=(x+3)(x-2)

x=-3,2

Answer:

Step-by-step explanation:

You start with creating let statements.

Let x = the cost of each pencil.

Let y = the cost of each eraser.

Let z= the cost of each pen.

Then, you’d fill in information from the problem.

3x + 4y = 65

2z + y = 35

Now, you’d solve like a system of equations; meaning you can do elimination or substitution.

The individual costs of pencils and erasers given total costs and quantities in a system of equations.The cost of each pencil is $2.00, and the cost of each eraser is $3.00.

The cost of each pencil is $2.00, and the cost of each eraser is $3.00.

Let x be the cost of one pencil and y be the cost of one eraser.

Set up a system of equations using the given information:
2x + y = 35 (equation 1)
3x + 4y = 65 (equation 2)

Solve the system using any method such as substitution or elimination to find x = $2.00 and y = $3.00.

Step-by-step explanation:

Answer:

x = 71°

Step-by-step explanation:

The triangle is clearly an isosceles triangle.

We know that all interior measures of a triangle must add up to 180°.

So: 180° - 38° =  142°

Because it is an isosceles triangle, the other two missing angles must be equal.

142° ÷ 2 = 71°

Answer:

x=71

Step-by-step explanation:

Because of the side being marked 27, you know that the triangle is an isosceles triangle. That means that the other 2 angles would be congruent. To find the sum of the remaining angles, you need to subtract 38 by 180 degrees. (All of the angles in a triangle add up to 180) 180-38=142. Since we already know that the two remaining angles will be congruent, you take 142 and divide by 2 to get the final answer 71.  

m<4 means the measure of angle 4, in degrees.

since the two lines are parallel, angles that are diagonal from each other are equal (like 2 and 4). One of the angles that are diagonal from angle 4 is 38°, so angle 4 is also 38°.

Answer: 38°

Answer:

your answer should be 38 degrees.

Answer:

the son is 30 and the daughter is 15

Step-by-step explanation:

the mom is 55 in 15 years

100-55=45

45-30=15

15x2=30

Answer:

15 and 5

Step-by-step explanation:

Mother's current age:  40

daughter's age:  d

son's age:  s

son is 2x as old as daughter:  s = 2d

Then, 15 years from now, the sum of their ages will be:

(40 + 15) + (2d + 15) + (d + 15) = 100

or

55 + 15 + 15 + 3d = 100

85 + 3d = 100, or 3d = 15, or d = 5.

Then the son's age is 3(5) = 15 and the daughter's is 5.

From the function sin(x+y) - sin(x-y) = 2f(x)sin(y), we can deduce that f(x) = cosx

But sin(x + y) = sinxcosy + cosxsiny.

Also, sin(x - y) = sinxcosy - cosxsiny..

Hence:

sin(x+y) - sin(x-y)

= sinxcosy + cosxsiny - (sinxcosy - cosxsiny)

=  sinxcosy -  sinxcosy + cosxsiny + cosxsiny

= 2cosxsiny

2cosxsiny = 2f(x)sin(y)

Hence, f(x) = cosx

Step-by-step explanation:

The exact response will depend a lot on what you learned in your manual and the terms used in it, but the metric system is all based on the base of 10, like the numbers system you use every day.

Unlike the US/Imperial system where there's no clear relation between an inch, a yard and a mile for example, in the metric system everything is related by the factor 10 somehow.

The unit multiplier is also used as a prefix to identify measurements.  Like for meter...

10 meters = 1 decameter

100 meters = 1 hectometer

1000 meters = 1 kilometer
