Answer:
The diameter of both is 8.
Step-by-step explanation:
The ratio is 4 of the first circle. And d=2r. So the diameter is 8.
Answer:
3/8 is less then 7/12
Step-by-step explanation:
Answer:
91%
Step-by-step explanation:
We can use the formula 
- "is" is 90
- "of" is 99
- "percent" is what we are solving for so we will denote it as x
Substituting in our values we get 
- We will need to cross multiply here to get (90)(100) = (x%)(99)
- This simplifies to 9000 = 99x%
- Dividing by 99 on both sides we get 90.9% → x = 91%
The equation looks like this:
26=x*3.5+8.50
where x is the number of pen you bought.
We solve it like this:
first, we subtract 8.50 from both sides:
17.50 =3.5*x
now we divide both sides by 3.5:
5=x
so you purchased 5 pens.
Answer:
I am about 95% sure that this is what they want. P.s (sorry I cant put the divide symbol)
<u><em>The variable is the number of shirts she bought or x</em></u>
and the equation is <u><em>(375+50) divided by (15+2) = x</em></u>
in the solve spot put
<em><u>(375+50) divided by (15+2)=x</u></em>
<em><u>425 divided by 17=x</u></em>
<em><u>x=25</u></em>
Then your answer would be <u><em>25</em></u>
Step-by-step explanation:
first add 50 to 375 so you get the full price which will give you 425. then to find out how many shirts she bought you must add 2 to 15 to get 17. then divide 425 by 17 which is 25. so she bought <em><u>25 shirts</u></em>.
