Answer:

4

Step-by-step explanation:

20 percent is 1/5. 1/5 of 20 is 4.

You would need to shade in 4 parts.

20% of something is equal to 1/5 (because 100/5=20), so you would need to find 1/5 of 20. You can do this by dividing 20 by 5, and 20 ÷ 5 = 4.

The volume of a dollhouse is V=24×8×10+1/2 ×24×6×8. Therefore, the correct answer is option A.

Volume is the measure of the capacity that an object holds.

Formula to find the volume of the object is Volume = Area of a base × Height.

Given that, Jasper built a dollhouse for his younger sister.

A rectangular prism has a length of 24 inches, width of 8 inches, and height of 10 inches.

We know that, the formula to find the volume of a rectangular prism is Length×Width×Height

Now, V₁ =24×8×10

= 1920

A triangular prism has a triangular base of 24 inches and height of 6 inches. The height of the prism is 8 inches.

V₂=Area of triangle ×Height

= 1/2 ×24×6×8

= 12×6×8

= 576

So, equation is V=V₁+V₂

V=24×8×10+1/2 ×24×6×8

Therefore, option A is the correct answer.

The shown triangle is scalene and right, so the correct options are C and F.

First, we can see that the 3 sides have different measures. So the triangle is Scalene (and we discard options A and E).

We also can see that one of the angle is 90°, which means that we have a right triangle. So option C is correct. (And we discard B and D).

Concluding, we have a scalene right triangle. So the correct options are C and F.

Step-by-step explanation:

Answer:

In order for his sample to be representative of all middle school students Leo: C) Should also take a sample from each of the other history classes in all of the other grades in the middle school.

What is sample?

Sample can be defined as the data that is randomly collected by a researcher so as to reach or draw a conclusion.

Since only one grade is being surveyed which is Mr. Barnes’s eighth-grade history classes, he should as well carryout the survey on Ms. Lopez and Mrs. Frank history class.

In conclusion he should also take a sample from each of the other history classes in all of the other grades in the middle school.

Final answer:

Leo should improve his survey method by sampling students from all eighth-grade history classes, including those of Ms. Lopez and Mrs. Frank, to ensure that each student has an equal chance of being selected and to obtain a representative sample of the middle school population.

Explanation:

Leo aims to determine the average number of texts middle school students send in a day. To ensure his sample is representative of the entire middle school student population, he should consider the sampling method. While he randomly surveyed students from Mr. Barnes’s eighth-grade history classes, only selecting students from a single teacher's classes might not guarantee a representative sample.

Thus, Leo should extend his survey to include students from Ms. Lopez’s and Mrs. Frank’s classes, which will give every student an equal chance of being chosen. This is important because it would include a wider range of perspectives and reduce the chance of sample bias. If Leo's goal is to understand the average texting behavior of all middle school students, and not just those in eighth grade, he should ideally sample students from other grades as well. However, if his focus is specifically on eighth graders, then sampling from all eighth-grade history classes should suffice.

Step-by-step explanation:

To divide

[tex]\frac{r_{1(cosx_{1}+isinx_{1}) } }{r_{2}(cosx_{2}+isinx_{2}) }[/tex]

= [tex]\frac{r_{1} }{r_{2} }[/tex] [ cos(x₁ - x₂) + isin(x₁ - x₂)

Given

[tex]\frac{2(cos90+isin90}{4(cos50+isin50)}[/tex]

= [tex]\frac{2}{4}[/tex] ( cos(90 - 50)° + isin(90 - 50)°

Answer:

80 units.

Step-by-step explanation:

If it is a rectangular prism, then it is 5×2×8, which is 10, from the 5×2 and 8. 10×8 is 80. So the final answer is 80 units cubed. Hope this helps! If you are still confused, please comment so I can help you!

Rectangular Prism: 80 units^3

V = lwh = 5(2)(8) = 80 units^3

Triangular Prism: 40 units^3

V = [tex]\frac{bhl}{2}[/tex] = [tex]\frac{5(2)(8)}{2}[/tex] = [tex]\frac{80}{2}[/tex] = 40 units^3

Answer:

Step-by-step explanation:

There is a common difference d between consecutive terms in the sequence, that is

9 - 5 = 5 - 1 = 1 - (- 3) = 4

This indicates the sequence is arithmetic with n th term

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = - 3 and d = 4, thus

[tex]a_{n}[/tex] = - 3 + 4(n - 1) = - 3 + 4n - 4 = 4n - 7 ← explicit formula

Thus

[tex]a_{80}[/tex] = 4(80) - 7 = 320 - 7 = 313

Answer:

84cm3

Step-by-step explanation:

Volume of the box = Area x Height

V = AH

From the question given,

Height = 12cm

Area = 7cm2

Volume =?

Volume = Area x Height

Volume = 7 x 12

Volume = 84cm3

Therefore, the volume of the cereal box is 84cm3

The volume of the cereal box is 84 cm³

From the question, we are to determine the volume of the cereal box

The volume of the cereal box can be calculated using

Volume = Base area × Height

From the given information

Base area = 7cm²

Height = 12 cm

Then,

Volume of the cereal box = 7cm² × 12cm

Volume of the cereal box = 84 cm³

Hence, the volume of the cereal box is 84 cm³.

Answer:

Step-by-step explanation:

The regular price, r of the ingredients before the discount is $40.

Percentage is defined as the parts of a number per fraction of 100. We have to divide a number with it's whole and then multiply with 100 to calculate the percentage of any number. So the percentage actually means a part per 100.

Percentage is usually denoted by the symbol '%'.

Amount spent by Matias' stepmother to buy the ingredients for huevos rancheros = $28

This is the discounted price after a 30% off discount.

Let the regular price be x.

x - (30% of x ) = 28

x - (0.3 x) = 28

0.7x = 28

x = 28 / 0.7

x = 40

Hence the original price of the items is $40.
