Answer:
Step 1: We make the assumption that 850 is 100% since it is our output value.
Step 2: We next represent the value we seek with $x$x.
Step 3: From step 1, it follows that $100\%=850$100%=850.
Step 4: In the same vein, $x\%=153$x%=153.
Step 5: This gives us a pair of simple equations:
$100\%=850(1)$100%=850(1).
$x\%=153(2)$x%=153(2).
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have
$\frac{100\%}{x\%}=\frac{850}{153}$
100%
x%=
850
153
Step 7: Taking the inverse (or reciprocal) of both sides yields
$\frac{x\%}{100\%}=\frac{153}{850}$
x%
100%=
153
850
$\Rightarrow x=18\%$⇒x=18%
Therefore, $153$153 is $18\%$18% of $850$850.
Step-by-step explanation:
Got this off of the web ages ago i got a question like this and this is what i wrote
We know that
[length of a circumference]=2*pi*r
diameter=90 cm-------------> r=d/2--------> r=45 cm
[length of a circumference]=2*pi*45----------> 90*pi cm
<span>with 1 revolution will go the length of the wheel</span>
if 1 revolution is-------------------> 90*pi cm
5 revolution is--------------------> X
X=5*90*pi----------> 1413 cm
the answer is 1413 cm
Answer:
3
Step-by-step explanation:
The factor (x - 8) has 1 zero at x = 8
The factor (x + 3)² has a zero at x = - 3 of multiplicity 2
In total there are 3 zeros
1. B and D
2.A
I hope this helped, woof.
