Answer:

A=4

B=3

C=2

D=1

Step-by-step explanation:

Answer:

We can write out 3! (three factorial) as 3x2x1, and we can write out 5! as 5x4x3x2x1. This means that, since 3x2x1 is on the top and the bottom of the fraction, it cancels out. This leaves us with 1 on top, and 4x5=20 on the bottom.

Answer:

When the slopes of lines a and b are multiplied, the product is −1.

Line a and line b intersect to form four right angles.

Step-by-step explanation:

Given

Perpendicular lines a and b

Required

Select the true statements

Represent the slope of line a with [tex]m_1[/tex] and the slope of b with [tex]m_2[/tex].

The condition for perpendicularity is:

[tex]m_1 * m_2 = -1[/tex]

Solving further:

[tex]m_1 = -\frac{1}{m_2}[/tex]

To solve further, we need to analyze each of the given options

(a) This is not true because the slope of perpendicular lines are not reciprocal

(b) This is also not true because perpendicular lines do not necessarily have to intersect at their midpoints

(c) This is true because of the condition stated above: [tex]m_1 * m_2 = -1[/tex]

(d) This is also true because perpendicular lines form right angles when they intersect

(e) This is not true because of the condition stated above: [tex]m_1 = -\frac{1}{m_2}[/tex]

(f) This is not true because of the condition stated above: [tex]m_1 = -\frac{1}{m_2}[/tex]

The product of the slope of the perpendicular lines is negative of one. Then the correct options are B and C.

It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.

Lines a and b are perpendicular.

Then the product of the slope of the perpendicular lines is negative of one. That is given as

[tex]\rm m_1*m_2 = -1[/tex]

a.  The slopes of lines a and b are reciprocals Line a and line b intersect at their midpoints. This is false.

b.  When the slopes of lines a and b are multiplied, the product is −1. This is true.

c.  Line a and line b intersect to form four right angles. This is true.

d.  The slopes of lines a and b are equal. This is false.

e.  The slopes of lines a and b are opposites. This is false.

Answer:

The option which is used to inscribe a square in a circle is option B

B. Construct a perpendicular bisector of the diameter of the circle

Step-by-step explanation:

The steps required to inscribe a square in a circle are;

1) Draw the circle using a compass

2) Draw the diameter of the circle, that passes through the center of the circle with a straight edge label the endpoint of the diameter X and Y

3) Construct the line perpendicular to the diameter of the circle and label the endpoints as A and B

The figure formed by joining the endpoints X, Y, A, and B is the inscribed square of the circle

Therefore, the correct option is to construct a perpendicular bisector of the diameter of the circle.

Answer:

8 ft.

Step-by-step explanation:

V = Bh        B = area of the base           h = height

The base is a circle, so [tex]B = \pi r^{2}[/tex]

320π = [tex]\pi r^{2} (20) = 20\pi r^{2}[/tex]

[tex]r^{2} = \frac{320\pi }{20\pi } = 16[/tex]

r = 4

d = 8 ft.

Answer:

3 31/36 inches

Step-by-step explanation:

11 1/9 = 100/9

7 1/4 = 29/4

100/9 = 400/36

29/4 = 261/36

400/36 - 261/36 = 139/36

139/36 = 3 31/36

Answer:

12 fish are girls

Step-by-step explanation:

multiply 4/6 by 6 which would be 24/36. Then substract 24 from 36 and you get 12.

Answer:

12 are girls

Step-by-step explanation:

Reason that since 4/6 of them are boys then that means 2/6 are girls

then convert 2/6 to decimal form which is 0.3333....

then multiply that by 36 which gives us 12

you could also go the roundabout way and convert 4/6 to decimal form and take that value and multiply it by 36 which gives us 24 then subtract 24 from 36 which still gives us 12

Answer:

(9, 57/7)

Step-by-step explanation:

Given the coordinates A(5 , 5)  and B(19 , 16), divided by the point P in the ratio 5:2, to get the coordinate of P, we will use the formula;

P(X, Y) = {{ax1+bx2/a+b, ay1+by2/a+b}

X = ax1+bx2/a+b

Substitute the given values

X = 5(5)+2(19)/5+2

X = 25+38/7

X = 63/7

X = 9

Similarly;

Y = 5(5)+2(16)/5+2

Y = 25+32/7

Y = 57/7

Hence the coordinate of point P is (9, 57/7)

Step-by-step explanation:

2^0+4=5

2^3 +4=12

2^7+4=132

Answer:

1. m = 65°

x = 30°

2. x = 40°

Step-by-step explanation:

1. Since the figure is an isosceles triangle, m = 2x - 5

180 - 50 = 130 (Total degree for both m and 2x - 5)

130 ÷ 2 = 65 (m and 2x - 5 angle degrees)

65 - 5 = 60 (2x)

2 x = 60°

x = 60 ÷ 2 = 30°

2. I forgot the parallel rule for question 2, but I think X and 40° is parallel to each other?
