Answer:
60 seconds
Step-by-step explanation:
step 1.) find how many meters it falls per second
40m / 4sec = 10m/s
step 2.) use the equation above to find in terms of the question
10m/s for 6sec = 10 x 6 ====> 60 seconds
The product has decreased by 80 %
<em><u>Solution:</u></em>
The product of the original numbers: xy
One number is decreased by 75 %
Let x be the number decreased by 75 %
new number = x - 75 % of x
Another number is decreased by 20 %
Let y be the number decreased by 20 %
new number = y - 20 % of y
<em><u>Now the product is given as:</u></em>
<em><u>Now we have to find the percent decreased</u></em>
Subtract new product and original product and then divide by original product . Multiply the result by 100 to get percentage
Here negative sign denotes decrease
Thus the product has decreased by 80 %
y = 12000x + 35000
When Mr. Nicolas began recording, it means, at 0 hour, how many tortillas was produced?
Subs x by 0.
y = 12000.0 + 35000
y = 0 + 35000
y = 35000
When Mr. Nicolas began recording the data, 35,000 tortillas had already been produced
The total number of tortillas produced 2 hours after the he began, it means, when x = 2
y = 12000 . 2 + 35000
y = 24000 + 35000
y = 59000
The total number of tortillas produced 2 hours after he began recording the data was 59,000
The total number of tortillas produced _ hours after he began recording the data was 85,000
Now we have y but not x.
y = 12,000x + 35,000
85,000 = 12,000x + 35,000
85,000 - 35,000 = 12,000x
50,000 = 12,000x
x = 50/12
x = 25/6
x = 4,1666...
Rounding
x = 4,167
To find the volume of a square-based pyramid, use the formula V = A(h/3), where V is the volume and A is the area of the base.
