Answer:

50

Step-by-step explanation:

We are finding the surface area of a circle here. which is pie r ^2 ( the formula) so the radius is 4. So we do pie 4^2 which equals 50.26548246 which is approximately 50.

Answer:

First, we must know the formula for the area of a circle.

The formula for the area of a circle is;

Where 'π' is pi(22/7 or 3.14), and 'r' is the radius which is being squared.

R(radius) = 4 feet.

So,

A = π\(r^{2}\)

Will be;

A = π(4^2) ← what I mean by " ^ ", I mean "to the power of".

Simplify:-

A = 3.14(16)

A = 50.24 feet is the area.

A) There are more workers in the L.A area that take up to 20 minutes to get to their job.

B)40 minutes or more.

Step-by-step explanation:

Even though the graph from the New York area is more well distributed, you can see a clear increase in the number of cases above 40 minutes in the New York area compared to the Los Angeles, which are probable around 3o workes, while in the New York Area graph those travel times are reserved for more than half of the workers that were interviewed, so we can assure that workers from the New York Area spend more time traveling to their jobs.

Carlos needs to earn at least 16 points on the final quiz to earn at least a 90% average.

We have,

Let's start by finding the total number of points that Carlos can earn in the class:

Total points

= 5 quizzes x 20 points per quiz

= 100 points

If Carlos needs an average of 90% or greater, that means he needs to earn at least 90 points out of 100.

Total points earned.

= 18 + 19 + 17 + 20

= 74 points

To find the minimum score Carlos needs on the final quiz, we can set up an inequality:

(74 + x) / 5 ≥ 0.9

where x is the score on the final quiz.

Simplifying this inequality.

74 + x ≥ 90

x ≥ 16

Therefore,

Carlos needs to earn at least 16 points on the final quiz to earn at least a 90% average.

The answer is option D. 12.2

Answer:

130° and 310°

Step-by-step explanation:

the bearing of A from B is the measure of the clockwise angle from a north line at B to A

the angle at B and A are same- side interior angles and sum to 180°

angle at B = 180° - 50° = 130°

the bearing of A from B is then 130°

the bearing of B from A is the measure of the clockwise angle from the north line at A to B

the complete angle about A = 360° then clockwise angle from north line at A to B is

360° - 50° = 310°

the bearing of B from A is 310°

Answer:

the answer is D. F(x) = 1/x(x-3)

Step-by-step explanation:

To find the value of x, we can set the two angle measures equal to each other and solve for x.

Given:

mZA = (4x - 2)°

mZB = (6x - 20)°

Setting them equal to each other:

4x - 2 = 6x - 20

Now, we can solve for x:

4x - 6x = -20 + 2

-2x = -18

Dividing both sides by -2:

x = -18 / -2

x = 9

Therefore, the value of x is 9.

Answer:

The answer is 9.

Step-by-step explanation:

We need to use the fact that the sum of the angles in a triangle is 180 degrees. Let A, B, and C be the three angles in the triangle. Then we have:

mZA + mZB + mZC = 180°

Substituting the given values, we get:

(4x - 2)° + (6x - 20)° + mZC = 180°

Simplifying the left side, we get:

10x - 22 + mZC = 180°

Next, we use the fact that angles opposite congruent sides of a triangle are congruent. Since we know that segment AC and segment BC are congruent, we have:

mZA = mZB

Substituting the given values and simplifying, we get

4x - 2 = 6x - 20

Solving for x, we get:

x = 9

Therefore, the value of x is 9.

Answer:

regrouping: 1  1

first addend: 2 8 7

second addend:  5 6

sum: 3  4  3

Step-by-step explanation:

first: add the digits in the ones column  

2  8  7

+   5  6

        13

because the answer is two digits, you leave the digit in the ones space in the answer, and move the digit in the tens space to the regrouping area above the tens column in the problem. it should look like this:

  1

2  8  7

+  5  6

       3

then add the digits in the tens column. you also add the regrouped number.

   1

2  8  7

+  5  6

   14 3

once again, the answer is two digits, so you repeat the same process, except since the digits are already in the tens place, you move the first digit above the hundreds place:

1   1

2  8  7

+  5  6

   4 3

add the hundreds column:

1   1

2  8  7

+  5  6

3  4  3

In a parallelogram ABCD, if point C lies on the line x = −1, then the y-value of C is option C: 0.

What is a parallelogram?

A quadrilateral with two sets of parallel sides is referred to as a parallelogram. In a parallelogram, the opposing sides are of equal length, and the opposing angles are of equal size. Additionally, the interior angles that are additional to the transversal on the same side.

Since ABCD is a parallelogram, it is known know that opposite sides are parallel.

Therefore, the slope of side AB is the same as the slope of side CD, and the slope of side BC is the same as the slope of side AD.

The points B and C both lie on the line x = -1.

Therefore, the x-coordinate of point C is also -1.

Use the slope of side BC to find the y-coordinate of point C.

The slope of side BC can be found as -

slope of BC = (y-coordinate of C - y-coordinate of B) / (-1 - 1)

slope of BC = (y-coordinate of C - 2) / (-2)

Since side AD is parallel to side BC, it has the same slope.

The slope of side AD can be found as -

slope of AD = (y-coordinate of D - y-coordinate of A) / (-1 - 1)

slope of AD = (2 - 4) / (-2) = 1

Since the slopes of two parallel lines are equal so -

slope of AD = slope of BC

Therefore, equate the two slopes and solve for the y-coordinate of point C -

1 = (y-coordinate of C - 2) / (-2)

Multiplying both sides by -2 -

-2 = y-coordinate of C - 2

Adding 2 to both sides -

y-coordinate of C = 0

Therefore, the y-coordinate of point C is 0.

Figure ABCD is a parallelogram. If point C lies on the line x = −1, what is the y-value of point C?

We can deduce that option A is likely to be true based on the given graph of rolling dice median data.

The median is the value in the middle of a data set, which means that 50% of the data points have a value less than or equal to the median, and 50% of the data points have a value greater than or equal to the median.

The graph illustrates that the median value of the rolls is closer to the center of the possible outcomes (numbers 3, 4, and 5) than the extremes (numbers 1 and 6).

This implies that when rolling a dice several times, the median is less likely to fall between the numbers 1 and 6.

However, because rolling the dice is a random process, there is always a degree of uncertainty in predicting the outcomes.
