Answer:

Step-by-step explanation:

the shape is made up of 2 circles and one box add the 3 areas up

circle area = $\pi$ $r^{2}$

3.14* $4^{2}$ = 50.24

50.24*2 =100.48

box, box, pit now :P ooh I was thinking formula one racing, ( i've been watching that lately) anyway

box = 8*8 = 64

total = 164.48 is that an option? hmm, yes the bottom two choices.. now the perimeter . the perimeter is made up of the 2 circles

the circumference of a circle is 2 $\pi$ r

2* $\pi$ *r

2* $\pi$ *4 =25.1327 that's one whole circle , multiplied by 2 , I can see , by math in my head that's about 50.26

sooo

the 3rd choice looks good :)

If you pick a gumball at random, put it back, and then pick another gumball at random, what is the probability of picking a blue

Fynjy0 [20]

Hi there!

It depends on how many colors of gumballs there are and how many gumballs there are in total. With those, we can set the fraction to each gumball color.

Hope this helps!

1/2 + 5/3 - 1<br>------------------<br> 3/4

Hey there :)

$\frac{ \frac{1}{2}+ \frac{5}{3} -1 }{ \frac{3}{4} }$
↓ Is the same as
$\frac{1}{2} + \frac{5}{3} -1$ ÷ $\frac{3}{4}$

Since it is a division by fraction, we can multiply by what is called the reciprocal
( The attached picture might help you )
( $\frac{1}{2} + \frac{5}{3} - 1$ ) × $\frac{4}{3}$
↓ For this part, we need the common denominator, which is 6
$\frac{1(3)}{2(3)}+ \frac{5(2)}{32)} \frac{1(6)}{1(6)}$ × $\frac{4}{3}$

$\frac{3}{6}+ \frac{10}{6} - \frac{6}{6}$ × $\frac{4}{3}$
$\frac{7}{6}$ × $\frac{4}{3}$
$\frac{14}{9} = 1\frac{5}{9}$
