5/2 = 2.5
180 * 2.5 = 450
Answer:
Step-by-step explanation:
Given
of child's age
Solving (1):
Determine the cost function.
Represent the years as y.
So, we have:
* y
Convert 25 cents to dollars.
So, we have:
The cost amount is then:
--- This is the cost function
Solving (b): Cost of 9 years old.
In this case;
Substitute 9 for y in
--- This is the cost for a child of 9
Answer:
1.) divisor multiplied by the proper power of ten = 131
2.) dividend multiplied by the proper power of ten = 47
3.) quotient = 2.787
Step-by-step explanation:
1. To make the divisor a whole number you should multiply it by = 100
And the divisor and the dividend must be multiplied by the same power of ten, that is = 100.
So, multiplyind the divisor by = 100:
And multiplyind the dividend by = 100:
2. Obtain the quotient:
Using the calculator you obtain the quotient between divisor and dividend:
Answer:
x = 52
Step-by-step explanation:
Formula
Combine the left
Multiply both sides by 4
4*(48 + x)/4 = 25 * 4
48 + x = 100 Subtract 48 from both sides
48 - 48 +x = 100 - 48 Combine
x = 52
46. 6*3=18 hence x=9*3=27 (ratio is 3:1)
47. x=8 clearly 2:1 ratio.
48.ratio is 1/3 hence, x=9/3=3
49.7:1 ratio. so, x=70
I hope you got the hang of it. so do the last two yourself.
