Select all the expressions that are equivalent to 16x - 12 - 24x + 4
1) 4 + 16x - 12(1 + 2x)
2) 40x - 16
3) 16x - 24x - 4 + 12
4) -8x - 8

Answers

Answer 1

Answer:

(1) and (4)

Step-by-step explanation:

4 + 16x - 12(1 + 2x) = 4 + 16x - 12 - 24x

4 + 16x - 12 - 24x = 16x - 12 - 24x + 4

- 24x + 16x = -8x

- 12 + 4 = -8

Which creates -8x - 8

Answers

Answer:

Rhombus and angle 1 = 35

Step-by-step explanation:

The parallelogram has the same marking on each of its sides, indicating that all the sides are equal in length. It is, therefore, a rhombus.

It is given that one of the angles measures 110 degrees. The other angle is 70 degrees (because 180 - 110 = 70). Since it is bisected by a line, divide the angle by 2 (70/2). You get 35 degrees. Therefore, the measure of angle 1 is 35 degrees.

A. 41 ft 3 in
B. 42 ft 4 in
C. 41 ft 2 in
D. 40 ft 6 in

Answers

Answer:

41 ft 2 in

Step-by-step explanation:

Since the two triangles in question, that means that the triangles have the same proportions. We know that GH = 16 ft 7 in = 199 in (16x12+7) and HN = 6 ft 3 in = 75 in (6x12+3). GH/HN is 199/75. This is the same ratio that GO/AN will have as well. GO is unknown so we will denote it as x and AN = 15 ft 6 in = 186 in (15x12+6). We know that these two fractions are equal. 199/75 = x/186 solving for x, we get x = 493.52 in and converting that into feet we get 41 ft 1.52 in which rounds to 41 ft 2 in.

A family just removed a big tree from their backyard. The diameter of the circular hole left behind is 7 feet across. Approximately how many square feet of grass will the family need if they want to cover the area where the tree once was?


A
22 ft²
B
39 ft²
C
44 ft²
D
154 ft²

Answers

The answer is c I hope this helps

The family needs to cover 39ft² area of grass.

What is Area of Circle?

The area of a circle is the amount of space enclosed within the boundary of a circle. The region within the boundary of the circle is the area occupied by the circle.

Here, Diameter = 7 ft.

          Radius = 7/2 ft. = 3.5 ft.

The Area of Circle = πr²

              A = 3.14 X (3.5)²

              A = 3.14 X 3.5 X 3.5

             A = 38.465 ft² ≈ 39 ft²

Thus, the family needs to cover 39ft² area of grass.

Mario plays basketball on a town league team. The
table below gives Mario's scoring statistics for last
season. How many points did Mario score playing
basketball last season?

Answers

Answer:

Step-by-step explanation:

Total points Mario scored = total 1-point free throw + total 2-point field goal + total 3-point field goal.

In 80 attempts 1-point free throw, Mario had 75% success rate. That is, Mario had 80 x 75/100 success

80 x 75/100 = 60

Thus, Mario scored 1 x 60 (since for each success, 1 points is added) points = 60

In 60 attempts 2-point field goal, Mario had 90% success rate. That is, Mario had 60 x 90/100 success

60 x 90/100 = 54

Thus, Mario scored 2 x 54 points (since for each success, 2 points are added) = 108

In 60 attempts 3-point field goal, Mario had 25% success rate. That is, Mario had 60 x 25/100 success

60 x 25/100 = 15

Thus, Mario scored 3 x 15 points (since for each success, 3 points are added) = 45

Therefore, the total points Mario scored = 60 + 108 + 45

= 213

Lin runs 5 laps a track in six minutes how many minutes per lap is that

Answers

Answer:

1.2 minutes

Step-by-step explanation:

6 divided by 5 = 1.2

To do this, you take the total number of minutes, which is 6, and divide by the number of laps that Lin ran, which was 5.

Answer:

1.2 minutes

Step-by-step explanation:

5 laps/6 minutes = 1 lap/x minutes

To convert the ratio from 5 laps to one laps, 5 was divided by 5. Therefore, to keep the same ratio, 6 must also be divided by 5, making the answer:

1 lap/1.2 minutes
