The formula P=2l+2w solve for w not l

1 answer:

8 0

That's the perimeter of a rectangle or parallelogram.

$p = 2l + 2w$

$p - 2l = 2w$

$\frac 1 2(p- 2l) = 2$

$w = \frac p 2 - l$

leva [86]

ANSWER: 1.562
move the decimal point of 0.0034 to the right to make it a whole number which is 34. Then multiply 34 times 430 which is 15,620.
move the decimal point (which is at the end) 4 times to the left
the answer will be 1.562

Find the values of x, y, and z. The diagram is not to scale.

Kruka [31]

we know that

The sum of the internal angles in the triangle must be $180$ degrees

see the attached figure with letters to better understand the problem

Step $1$

Find the measure of the angle x

In the triangle ABC

$63\°+36\°+x\°=180\°$

solve for x

$99\°+x\°=180\°$

$x\°=180\°-99\°$

$x=81\°$

therefore

the answer Part a) is

the measure of angle x is $81\°$

Step $2$

Find the measure of the angle z

we know that

$x+z=180\°$ --------> by supplementary angles

substitute the value of x

$81\°+z=180\°$

$z=180\°-81\°$

$z=99\°$

therefore

the answer Part b) is

the measure of angle z is $99\°$

Step $3$

Find the measure of the angle y

In the triangle ACD

$13\°+z\°+y\°=180\°$

solve for y

$13\°+99\°+y\°=180\°$

$112\°+y\°=180\°$

$y\°=180\°-112\°$

$y\°=68\°$

therefore

the answer Part c) is

the measure of angle y is $68\°$

Determine the required value of the missing probability to make the distribution a discrete probability distribution. x p(x) 3

Alisiya [41]

To get the required value of the missing probability to make the series complete is to deduct all the probability given to 1 because we know that the discrete probability distribution must be equal to 1. So doing what I have said, this will be:

P(4) = 1 - P(3) - P(5) - P(6)

= 1 – 0.3 – 0.18 – 0.21

= 0.31 is the answer.
