PLEASE HELP ! 12 POINTs! ABCD Is A Trapezium Calculate The Perimeter Of The Trapezium Give Your Answer

Answers

Answer 1

Answer:

Perimeter = 101.496 cm

Step-by-step explanation:

draw line from point C that is perpendicular to line AD. Call that point E.

tan 43° = 16.7/ED

0.9325 = 16.7/ED

ED = 17.909 cm

sin 43° = 16.7/CD

0.6820 = 16.7/CD

CD = 24.487 cm

Perimeter = AB + BC + CD + ED + AE

Perimeter = 16.7 + 21.2 + 24.487 + 17.909 + 21.2 = 101.496 cm

Answers

Answer:

No Solutions

Step-by-step explanation:

The two points are (3,2) and (-2,-2)

Slope is y change over x change.

So... -2-2 over -2-3 equals to -3-(-2) over -2-(-2).

That is -3+2 over -2+2 which is -2 over 0.

You can't divide by zero so the slope is "NoSolutions"

Solving the formula P = 2L + 2W for W is NOT equivalent to which equation?

Answers

Answer:

3rd one

Step-by-step explanation:

2l + 2w = P

2w = P - 2l

w = P - 2l / 2

Therefore, the equivalent equation to the given equation is [tex]w=P-\frac{1(L)}{2}[/tex].

What is the equation?

The definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.

Here given equation is

[tex]2L + 2w = P\\\\2(L+w)=P\\\\L+w=\frac{1}{2}P\\\\w=\frac{1}{2}P-L\\\\w=\frac{P-2L}{2}\\\\w=P-\frac{1}{2}L[/tex]

Hence, the equivalent equation to the given equation is [tex]w=P-\frac{1(L)}{2}[/tex].

A rectangle of length 14 cm and breadth 7 cm is folded into a right circular cylinder. How many revolutions does the cylinder need to make to cover an area of 784 sq.Cm

Answers

Answer:

n = 8

Step-by-step explanation:

Given that,

Length and breadth of a rectangle are 14 cm and 7 cm.

The area of rectangle is given by :

[tex]A=l\times b\\\\A=14\times 7\\A=98\ cm^2[/tex]

Let n be the number of revolutions the cylinder need to make to cover an area of 784 sq.cm.

So,

[tex]n=\dfrac{784}{98}\\\\n=8[/tex]

Hence, there are 8 revolutions.
