Answer:

problem 2 is correct

Problem 4 is - 2

Step-by-step explanation:

Number 2 is correct, however you obtained it.

Number 4 is almost correct.

Four

4x + 3 = - 5 Subtract 3 from both sides.

4x + 3-3=-5-3 Combine

4x + 0 = - 8

4x = - 8 Divide by 4

4x/4 = - 8/4 Do the division

x = - 2

Step-by-step explanation:

5 integers with an average of 44

⇒ sum of the integers = 5 x 44 = 220

The median is the middle number when the numbers are put in order of smallest to largest. So the integers are: x x 50 x x

The modal integer is the one that occurs most frequently, so if the mode is 52, then at least 2 of the integer are 52. Since the median is 50, the integers are: x x 50 52 52

Therefore, the remaining two integers are less than 50.

The range is the difference between the largest integer and the smallest integer. As we know that the largest integer is 52 and the range is 27, then the smallest integer is 52 - 27 = 25

25 x 50 52 52

To find the last unknown integer :

⇒ sum of the integers = 25 + 50 + 52 + 52 + x = 220

⇒ x = 41

Therefore, the integers are:

25, 41, 50, 52, 52

PLEASE HELPPPPPP FINDING CIRCUMFERENCE AND AREA OF A CIRCLE

11111nata11111 [884]

Answer:

The circumference of the circle is 28.26 m.

The area of the circle is 63.585 $m^{2}$ .

Step-by-step explanation:

To solve for the circumference of the circle, start by using the circumference formula of a circle, which is $C= 2\pi r$ . However, 3.14 will be used instead of $(\pi)$ for this formula.

First, the radius of the circle needs to be found. To find the radius of the circle, divide the diameter by 2 because the radius equals half of the diameter. The radius is 9 m divided by 2, which equals 4.5 m.

Next, plug in the radius into the formula, and the formula will look like $C=(2)(\pi )(4.5 m)$ . Then, solve the equation, and the answer will be 28.26 m.

To solve for the area of the circle, start by using the area formula of a circle, which is $A=\pi r^{2}$ . However, 3.14 will be used instead of $(\pi)$ for this formula.

For the area, plug the radius into the formula, and the formula will look like $A= (3.14)(4.5m)^{2}$ . Then, solve the equation, and the answer will be 63.585 $m^{2}$ .
