Step-by-step explanation:
Based on the given conditions,
Formulate:(100-80)÷80
Calculate the sum or difference:20/80
Cross out the common factor:1/4
Multiply a number to both the numerator and the denominator:1/4×25/25
Write as a single fraction :25/4×25
Calculate the product or quotient :25/100
Rewrite a fraction with denominator equals 100 to a percentage:25%
Answer : 25%
Answer:
You are correct. Nice job
Answer: A+C=500
7.5A+4.75C=3351.25
C=500-A
7.5A+4.75(500-A)=3351.25
7.5A+2375-4.75A=3351.25
2.75A=976.25
A=355 adults ($2662.50)
C=500-A=145 children ($688.75)
Step-by-step explanation:
To solve this problem lets assume, that the number 60 is 100% - because it's the output value of the task. <span>We assume, that x is the value we are looking for. </span><span>If 100% equals 60, so we can write it down as 100%=60. </span><span>We know, that x% equals 120 of the output value, so we can write it down as x%=120. </span>Now we have two simple equations:
<u>1)100%=60</u>
<u>2) x%=120</u>
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that: 100%/x%=60/120.
Now we just have to solve the simple equation, and we will get the solution we are looking for.
<em>Solution for 120 is what percent of 60</em>
<em>100%/x%=60/120</em>
<span><em>(100/x)*x=(60/120)*x - </em></span><em>we multiply both sides of the equation by x</em>
<span><em>100=0.5*x - </em></span><em>we divide both sides of the equation by (0.5) to get x</em>
<span><em>100/0.5=x </em></span>
<span><em>200=x </em></span>
<em>x=200</em>
<span><em>now we have: </em></span>
<span><em>120 is 200% of 60</em></span>
I'm not sure what the <span>879-06-03-00-00-con_files/i0040000.jpg stands for but I'll just solve the given choices and you can choose which is the correct one.
1 inch = 2.54 cm
a) 88.90 cm * 1inch / 2.54 cm = 35 inches </span>→ 35 inches = 88.90 cm . I THINK THIS IS THE CORRECT ANSWER TO YOUR QUESTION.<span>
b) 77.00 cm * 1inch / 2.54 cm = 30.31 inches </span><span>
c) </span><span>13.78 cm * 1inch / 2.54 cm = 5.43 inches
d.) 21.74 cm * 1inch / 2.54 cm = 8.56 inches</span>
