Which of the expressions are equivalent to the one below? Check all that apply.


4 • (8 + 3)

A. (4 • 8) + 3

B. (8 + 3) • 4

C. 4 • (3 + 8)

D. 4 • 8 + 4 • 3

Answers

Answer 1

Step-by-step explanation:

We need to find an expression that is equivalent to 4×(8+3)

We know that,

4×(8+3) = 4(11) = 44

Option (1).

(4 • 8) + 3 = 32+3 = 35. It is incorrect

Option (2).

(8 + 3) • 4 = (11) 4 = 44. It is correct.

Option (3).

4 • (3 + 8) = 4(11) = 44. It is correct.

Option (4).

4 • 8 + 4 • 3 = 32+12 = 44. It is correct.

Hence, the correct options are (2), (3) and (4).

Leslie shows a funny video to 5 of her friends. Every hour, the video

views triple. Leslie shows a funny video to 5 of her friends. Every hour, the video

views triple. How many people saw the video on the 7th hour? many total people saw the video after the 7th hour?

Answers

Answer:

10,935 views

Step-by-step explanation:

We can first design a formula for this scenario. Since the views triple this means that the initial views (i) needs to be multiplied by 3. Since this happens every hour we need to raise 3 to the power of the number of hours (h) that has passed by. This would give us the total number of views at that hour. Therefore, the formula would be the following...

i * [tex]3^{h}[/tex]

We can input the values given to us into the formula and solve it for the total number of view. The initial number of views would be 5 (one for each friend) while we are trying to find the total number of views in the 7th hour.

5 * [tex]3^{7}[/tex]

5 * 2187

10,935 views

The diameter of a circle is 55 inches.

​

​Find the length of its radius.

​

Answer:​
inches
​

Answers

The radius would be 8.75

Answer:

27.5 inches

Step-by-step explanation:

The circle's "radius" refers to the distance from the center towards the circumference. Once the diameter of a circle is given, it is easy to get the radius. In order to get the length of the circle's radius, all you have to do is to divide the diameter (55 inches) into two.

55 inches ÷ 2 = 27.5 inches

Therefore, the circle's distance from the center towards the circumference is 27.5 inches. This is the radius.

guys please help me it's Find the area of the polygon

Answers

For the first figure, draw a vertical line from the upper right corner to the base. Then you can see that the figure is a combination of two shapes: A rectangle that is 8 high and 6 wide, and a right triangle that has altitude of 8 and base of 4.

Area of rectangle = 8*6 = 48
Area of triangle = (1/2)*8*4 = 16
Total area = 48+16 = 64 square units
:::::
The second figure is a parallelogram with equal sides. Note that if you cut off the triangular area and attach it to the top of the figure, you get a rectangle, so the area is 15 times 16 = 24 units.
