675. Just subtract. 1000
- 325
Set it up like this.
Think of this as a proportion: 2.4 is to 100, as 34 is to L ("L" for "Long piece.")
Cross multiply to get 2.4 L = 3400, then divide both sides by 2.4 to be left with
L = 3400/2.4, so
L = 1416.666...
So the longer piece of wood is 1,416.66... inches long.
Hope this helps!!:)
Answer:
approximately 27 grams
Work Shown:
Half life formula
y = A*(0.5)^(x/H)
where,
A = starting amount = 30 grams
H = half life period = 90 years
x = number of years that pass by = 12
y = amount left over after x years
Let's plug the values for x, A and H into the formula to find y
y = A*(0.5)^(x/H)
y = 30*(0.5)^(12/90)
y = 27.3516746567466
y = 27 .... rounding to the nearest whole number

Step-by-step explanation:
Answer:
135 meters
Step-by-step explanation:
h = 60t - 5t²
t is in seconds and it says to find out the height after 3 seconds
Sub the value '3' into 't'
h = 60(3) - 5(3)²
h = 180 - 5(9)
h = 180 - 45
h = 135 m
