Answers

Answer 1

Answer:

(x + 6) (x - 1)

Step-by-step explanation:

2x² + 10x - 12

dividing by 2,

x² + 5x - 6

x² - x + 6x - 6

x(x - 1) + 6(x - 1)

(x + 6) (x - 1)

x = -6 or x = 1

Step-by-step explanation:

The area of the large triangle is 36*24/2

minus the small triangle which is 21*14/2

so 432-147 = 285

This is very hard to explain in text and not on paper, but I will try to explain it the best I can.

So first get the length of the bottom of the triangle, so that would be 36in. Minus 21in. Which will give us the length of the bottom of the shaded region.

36-21= 15 in.

This next step isn’t necessary, but it makes solving for the area so much easier. Make the shaded region into two different shapes. So in this case, a square and then a right triangle.

So take the height on both sides on the shaded region, which would be..

24 - 14 = 10in.

Now, multiply the length by the height to solve for the area of the square and triangle.

Triangle area: 15(10)= 150 sq. in.

Square area: 15(14)= 210

Now add them together and then you get your answer.

210 + 150 = 360 sq. in.

The area of the shaded region is 360 sq. in.



A DVD rental service wants to pay close attention to what movies their customers like the most. Which measure of central tendency will give them the best estimate? Explain.

Answers

Answer:

Mode.

Because it is used to determine the most frequently occurring item which in this case is movie.

Step-by-step explanation:

The 3 measure of central tendencies are namely;

Mean, median mode.

- Mean is defined as the average of a set of data.

- Median is the middle term of a set of data that splits that set of data into 2.

- Mode is the term that occurs most frequently in a set of data.

In this question, we want to find the movies most frequently watched.

Thus, from the definitions above earlier, it is clear that the only way to know this is using the mode.

Answer:

62

Step-by-step explanation:

119 is adjacent to angle x. angle x and 119=180 (because the angle of a straight line is 180.) which means to find angle x you have to subtract 119 from 180. 180-119=61. because you now know two angles in the triangle you can add the together and subtract them from 180 (remember 180 is what all the angles in a triangle should add up to 180). 61+57=118 and 180-118=62

A pair of jeans is normally priced at $56, but is currently marked down for with a 35% discount. What would replace the B in the proportion? A/B=P/100%

Answers

Answer:

$36.4

Step-by-step explanation:

Given

Cost of Jean = $56

Percent markdown = 35%

Discount = 35% of $56

Discount = 0.35 * 56

Discount = $19.6

New price = $56 - (35% of $56)

New price = $56 - 19.6

New price = $36.4

hence the price that will replace B is $36.4

consider a rectangular prism with length 4 and width and height d

Find an expression for the volume of the prisms in terms of d.

2. compute the volume of the prism when d=1, when d=2, and when d=1/2

Answers

Answer:

Step-by-step explanation:

The expression for the volume of the prisms in terms of d is 4d².

What is a volume?

Volume is the amount of space occupied by a three dimensional shape or object. For a rectangular prism:

Volume = length * width * height

From the diagram, length = 4, width = d, height = d. Hence:

Volume = 4 * d * d = 4d²

When d = 1: Volume = 4(1)² = 4

When d = 2: Volume = 4(2)² = 16

When d = 1/2: Volume = 4(1/2)² = 1

The expression for the volume of the prisms in terms of d is 4d².

F is inversely proportional to d^2. When F=9, d=4 Work out d (positive value rounded to 2 DP) when F=6

Answers

Answer:

d = 4.90

Step-by-step explanation:

Given the following data;

F = 9

d = 4

For an inversely proportional relationship, we have;

F = k/d²

Now, we would find the constant, k;

9 = k/4²

k = 9*16

k = 144

Next, to find d, when F = 6

d² = k/F

d² = 144/6

d² = 24

Taking the square root of both sides, we have;

d = 4.90

I need help ASAP find u and v

Answers

Answer:

u = 66

v = 38

Step-by-step explanation:

In a parallelogram, opposite angles are equal.  U is opposite to 66, so it is 66 degrees

In a parallelogram, corresponding angles are supplementary.  180 - 66 = 114

this means that 3v = 114.  114/3 = 38, which is what v is.
