About what percent of 212 is 400?

The answer to this arithmetic expression is approximately 9.9998 x 10¹⁸

A combination of numbers, variables, and operators that represents a quantity or mathematical relationship is called an expression.

First, divide sextillion (10²¹) by nonmillion (10⁶) to get 10¹⁵.

Next, multiply 10¹⁵ by 10,000 to get 10¹⁹.

Subtract 200 million (2 x 10⁸) from 10¹⁹ to get 9.9998 x 10¹⁸.

Finally, add 5,000 to get the result of approximately 9.9998 x 10¹⁸ + 5,000 = 9.9998 x 10¹⁸ + 0.0005 x 10¹⁸ = 9.9998 x 10¹⁸.

Therefore, the answer to this arithmetic expression is approximately 9.9998 x 10¹⁸

Answer:

50.27 cm

Step-by-step explanation:

We Know

The area of the circle = r² · π

Area of circle = 64π cm²

r² · π = 64π

r² = 64

r = 8 cm

Circumference of circle = 2 · r · π

We Take

2 · 8 · (3.1415926) ≈ 50.27 cm

So, the circumference of the circle is 50.27 cm.

Answer: C=16π cm or 50.24 cm

Step-by-step explanation:

The formula for area and circumference are similar with slight differences.

\(C=2\pi r\)

\(A=\pi r^2\)

Notice that circumference and area both have \(\pi\) and radius.

\(64\pi=\pi r^2\)        [divide both sides by \(\pi\)]

\(64=r^2\)             [square root both sides]

\(r=8\)

Now that we have radius, we can plug that into the circumference formula to find the circumference.

\(C=2\pi r\)          [plug in radius]

\(C=2\pi 8\)          [combine like terms]

\(C=16\pi\)

The circumference Is C=16π cm. We can round π to 3.14.

The other way to write the answer is 50.24 cm.

Follow-up pain Utilizing fresh gruesome milk, as usual Prior to, before, ahead of The slopes of thirty and sixty degrees, for example, are supplementary. In contrast to a supplemental angle, which is two angles joined to create a 90 degree angle, a supplemental angle involves two angles joined to create a 180 degree angle.

Here,

Given :

Let us consider first angle be x

and second angle is less than 36°

=>  x - 36°

So , there are complementary angle there sum will be equal to 90°

=> x + x - 36°  = 90°

If Lucinda used a random selection method, made an effort to ensure that the sample is representative, and the sample size is large enough, then it's possible that the sample is indeed random.

what are perpendicular lines?

Perpendicular lines are two lines that intersect at a 90-degree angle, forming four right angles at the point of intersection. In other words, if you were to draw a perpendicular line from one of the lines to the other at their point of intersection, it would form a right angle with each of the original lines.

Without having access to more information about how Lucinda selected the sample of students, it's difficult to determine whether or not the sample is truly random.

However, there are a few things that we can consider when trying to determine whether or not the sample is random. For example:

Did Lucinda use a random selection method to choose the students? If she simply surveyed her friends or classmates, for example, the sample would not be random.

Did Lucinda make any effort to ensure that the sample is representative of the larger population of students? For example, did she make sure to include students from a variety of grades, genders, and ethnic backgrounds.

Therefore, if Lucinda used a random selection method, and made an effort to ensure that the sample is representative, and the sample size is large enough, then it's possible that the sample is indeed random.

Angle A in triangle ABC is approximately 76 degrees. So, correct option is A.

In a right triangle, the side opposite the right angle is called the hypotenuse, and the other two sides are called the legs. Let's consider triangle ABC, where angle B is the right angle, AC is the hypotenuse, and BC is one of the legs.

We are given that AC = 33 and BC = 32. To find angle A, we can use trigonometric ratios. In this case, we can use the sine function.

The sine of angle A is defined as the ratio of the length of the side opposite angle A (BC) to the length of the hypotenuse (AC):

sin(A) = BC / AC

Substituting the given values, we have:

sin(A) = 32 / 33

Using the inverse sine function (sin⁻¹), we can find the value of angle A:

A = sin⁻¹(32 / 33)

Using a calculator, we find that angle A is approximately 75.85 degrees. Rounding off to the nearest angle we get 76 degrees.

Therefore, angle A in triangle ABC is approximately 76 degrees. So, correct option is A.

Step-by-step explanation:

Answer:

False.

Step-by-step explanation:

We have the ordered pair (10, 6) and we want to see if this ordered pair is a solution of the inequality:

y  ≤ -5/5x+3

Remember that a generic ordered pair is written as (x, y)

Then for the ordered pair (10, 6) we have:

x = 10

y = 6

So we just need to replace these two values in the inequality and see if the inequality is true or false.

Replacing these values we get:

6  ≤ (-5/5*10) + 3

6  ≤ (-1/10) + 3

This is false, 6 is not less than the thing at the right, so we can conclude that (10, 6) is not a solution of the inequality.

So the coordinate pair makes the inequality false.

The completed statement is: (3a^2 - 5ab * b^2) - (-3a^2 * 2b^2 + 8ab) = 9a^2 + 6a^2b^2 - 5ab^3 - 8ab

To complete the statement and simplify the expression, let's carefully expand and combine like terms:

(3a^2 - 5ab * b^2) - (-3a^2 * 2b^2 + 8ab)

First, let's distribute the negative sign inside the second parentheses:

(3a^2 - 5ab * b^2) + (3a^2 * 2b^2 - 8ab)

Next, let's simplify each term:

3a^2 - 5ab * b^2 = 3a^2 - 5ab^3

3a^2 * 2b^2 - 8ab = 6a^2b^2 - 8ab

Now, we can rewrite the expression:

(3a^2 - 5ab^3) + (6a^2b^2 - 8ab)

To combine like terms, we add or subtract the  of similar terms:

3a^2 + 6a^2b^2 - 5ab^3 - 8ab

So, the simplified expression is:

9a^2 + 6a^2b^2 - 5ab^3 - 8ab

Therefore, the completed statement is:

(3a^2 - 5ab * b^2) - (-3a^2 * 2b^2 + 8ab) = 9a^2 + 6a^2b^2 - 5ab^3 - 8ab

To solve the given problem, let the number of students in class yesterday be x.

There were 30 students in class today.

This is an increase of 25% from yesterday.

To calculate how many students were in class yesterday, we'll use the formula for percent increase:

% increase = (new value - old value) / old value * 10025%

= (30 - x) / x * 100

Option b is correct. The p-value for testing the claim there is a relationship between the quantitative variables would be more than 2.

Given that the 95% confidence interval for the difference in population proportions p1- p2 is between 0.1 and 0.18. Therefore, the option (a) None of the other options is correct is not correct.p-value: The p-value is the probability of observing a test statistic as extreme as or more than the observed value under the null hypothesis. The p-value is used to determine the statistical significance of the test statistic. A small p-value indicates that the observed statistic is unlikely to have arisen by chance and therefore supports the alternative hypothesis.a. False because the 95% confidence interval for the difference in population proportions p1- p2 is given. The confidence interval is used to determine the true population proportion. Thus, the option "None of the other options is correct" is incorrect.

b. True because the p-value for testing the claim that there is a relationship between quantitative variables would be more than 0.05 if the confidence interval for the difference in population proportions p1- p2 contains zero. Thus, option b is correct.

c. False because the p-value for testing the claim that there is a relationship between categorical variables would be less than 0.05 if the confidence interval for the difference in population proportions p1- p2 does not contain zero. Therefore, the option (c) The p-value for testing the claim there is a relationship between the categorical variables would be less than 0.05 is not correct.

d. False because the confidence interval only shows the range of the estimated proportion difference. It doesn't tell us anything about the relationship between quantitative variables. Therefore, option d is not correct.

An isosceles triangle is a triangle where two sides are equal and the angles opposite to the sides are also equal.

The value of y is 28.

It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.

We have,

An isosceles triangle is a triangle where two sides are equal and the angles opposite to the sides are also equal.

m∠CAB = 34

m∠CBA = x - 5

m∠ACB = 4y

Triangle ABC is an isosceles triangle.

AC and BC are sides are equal.

This means,

m∠CAB = m∠CBA

34 = x - 5

34 + 5 = x

x = 39

Now,

The sum of the angles in a triangle is 180 degrees.

This means,

34 + (x -5) + 4y = 180

34 + (39 - 5) + 4y = 180

34 + 34 + 4y = 180

68 + 4y = 180

4y = 180 - 68

y = 112 / 4

y = 28

We can cross-check.

34 + 34 + 4 x 28 = 180

34 + 34 + 112 = 180

180 = 180

Thus,

The value of y is 28.
