What is parallelogram?

In two-dimensional geometry, it is a plane shape having four sides, in which two pairs of sides are parallel to each other and equal in length. The sum of all angles in a parallelogram is 360°.

The two opposing sides are equal and parallel. The opposing angles line up evenly. The following or neighboring angles are extra. Every angle will be at a right angle if one of the other angles is even.

A parallelogram has equal opposite angles (or congruent) Angles that are next to one another are said to be consecutive (that means they add up to 180 degrees)

The true identities are,

AB=CD

m∠ABC + m∠BCD = 180°

Thus, statements D and E are true about ABCD.m∠ABC + m∠BCD = 180° and AB=CD.

A farm raises cows and chickens. The farmer has a total of 46 animals. One day he counts the legs of all his animals and realizes he has a total of 156 legs. How many cows does the farmer have?

Thanks in advance, I really appreciate it :)

Answers

Answer:

Step-by-step explanation:

lets note a= chickens

b=cows

a+b=46

also = chickens has 2 legs, cow=4 legs

2a+4b=156..........we divide this equation by 2 so we can work with smaller numbers

a+2b=78 or we cam write a=78-2b

lets replace in the first equation a+b=46

78-2b+b=46

-b=46-78

-b=-32  multiply by -1

b=32

so we have 32 cows with 128 legs

a+32=46

a=14 chickens with 28 legs

What is the equation of the line that passes through the point (4, -4) and has a
slope of ?

Answers

Answer:

[tex] y = -\frac{5}{2}x + 6 [/tex]

Step-by-step explanation:

Using a point (4, -4) and the slope of the line that passes through it, m = -⁵/2, we can generate an equation by using the point-slope form equation of a line given as y - b = m(x - a).

Where,

(a, b) = (4, -4)

m = -⁵/2

Plug in the values

y - (-4) = -⁵/2(x - 4)

y + 4 = (-5x + 20)/2

Multiply both sides by 2

2y + 8 = -5x + 20

Subtract both sides by 8

2y = -5x + 20 - 8

2y = -5x + 12

Divide both sides by 2

y = -⁵/2x + 12/2

[tex] y = -\frac{5}{2}x + 6 [/tex] (equation in slope-intercept form)

Based on Grandma's guide to cooking, how many pinches are in one teaspoon?

Answers

your answer is gonna be 16

Using proportions, it is found that there are 16 pinches in one teaspoon.

This question is solved by proportions, using a rule of three.One dash has 2 pinches. One teaspoon is the same as 8 dashes. How many pinches are there in 8 dashes?

Hence, the rule of three is:

1 dash - 2 pinches

8 dashes - x pinches

Applying cross multiplication:

How many distinct rearrangements of the letters in "sleepless" are there?

Answers

Answer:

[tex]N = 5040[/tex]

Step-by-step explanation:

Required

Arrange the letters of "sleepless"

First, we count the number (n) of characters

[tex]n = 9[/tex]

First, we count the number (n) of repeated characters

[tex]s = 3[/tex]

[tex]e = 3[/tex]

[tex]l = 2[/tex]

The arrangement (N) is then calculated as follows;

[tex]N = \frac{n!}{s!e!l!}[/tex]

This gives:

[tex]N = \frac{9!}{3!3!2!}[/tex]

[tex]N = \frac{9*8*7*6*5*4*3*2*1}{3*2*1*3*2*1*2*1}[/tex]

[tex]N = \frac{362880}{72}[/tex]

[tex]N = 5040[/tex]

Hence, there are 5040 distinct arrangements

Answers

Answer:

4000 miles.

Step-by-step explanation:

Answer:

If we know each miles are 1.6 km, we can do a rule of three to get the length of the river:

1    1.6

X   6400

Now, we know that  = 4000 miles

You can also just divide 6400/ 1.6 as each 1.6 kilometers are one mile

the triangle below?

A. 5.6
B. v32
C. 16
D. 4v2
E. 16v2
F. 1

Answers

E is the answer. Since it’s a 45 45 90 triangle the rules are the hypotenuse is equal to x squareroot of 2 while the two other sides are just equal to x. If Xv2= 32 then the two sides (x) must be equal to 16v2

The length of each leg of the given triangle is 16√2.

What is the triangle?

Triangle is a shape made of three sides in a two-dimensional plane. the sum of the three angles is 180 degrees.

The length of the leg is calculated by using the angle property. Use sin angle to calculate each leg.

First leg,

Sin45 = P / H

1 / √2 = P / 32

P = 32 / √2

P = 16√2

Second leg,

Sin45 = P / H

1 / √2 = P / 32

P = 32 / √2

P = 16√2

Therefore, the length of each leg of the given triangle is 16√2.
