Plug the known variables into the equation.
p=2l+2w
200=2l+2(30)
200=2l+60
140=2l
l=70
The answer is C. 70mm.

Nolini says that if the denominator is more than twice the numerator, the fraction can always be replaced with a 0. Is she corre
Len [333]

Answer:

yes

Step-by-step explanation:

It depends on how accurate you want your answer to be, but basically yes, imagine we set our numerator to be x, and our denominator to be 2x, if we built our fraction we will get that:

\frac{x}{2x}=\frac{1}{2}

If the denominator of a fraction is exactly twice the numerator, then the fraction will be simplified to 1/2 or 0.5.

Now, the greater the denominator is, the closer the fraction will get to zero.

Take for example I had an fraction like this:

\frac{3}{6}=0.5

which approximates to 0. If we made the denominator bigger, let's say 7, we would get:

\frac{3}{7}=0.43

notice the answer is closer to 0 this time, so it's valid to round it to zero. If we made the denominator greater, let's say 25, we would get:

\frac{3}{25}=0.12

and so on. So it is true that if the denominator of a fraction is greater than twice the numerator, we can always replace the fraction with a 0 (depending on how accurate you want your answer to be).

What is the value of r? pls answer asap
notka56 [123]

Answer:

R=22

Step-by-step explanation:

180-44= 136

136÷2= 68

90-68= 22

180 is angle of the straight line. 44 is subtracted to get angle of only the triangle on the left which is 136. 136 is then divided by 2 since the remaining two angles are equal and you'll get 68. R is part of a right-angled triangle (90°) subtract 68 from that and you will get 22

Gennadij [26K]

The answer is 121.225.

Step-by-step explanation:

Because you would start with turning 42 and 5/8 into 341/8 then do 341 divided by 8 to get 42.625 as the decimal, then start turning 393/5 into a decimal by 393 divided by 5 to get 78.6 as your decimal then add them together like this: 42.625 + 78.6 = 121.225 as your answer.

Claire threw the javelin 42.625 feet but grace threw the javelin 78.6 feet.

Your welcome!.
