Lizette ran for 1.25 hours and walked for 3 hours.
distance = speed × time
Her total distance is the sum of her distances at the different speeds. Let w represent her walking speed in mi/h. For distances in miles, speeds in miles per hour, and time in hours, the problem statement tells us ...
19 = (w+5)(1.25) + (w)(3)
19 = 4.25w + 6.25 . . . . collect terms
12.75 = 4.25w . . . . . . . subtract 6.25
3 = w . . . . . . . . . . . . . . . divide by 4.25
Lizette's walking speed is 3 mph.
Lizette's running speed is 8 mph.
Answer:
answer is if 1 plus 1 is 2 then that means the answer is 978
Answer:
12 slides
Step-by-step explanation:
Okay so we know that Val:
takes 1/6 hours to do each slide
has 2hrs
To figure this question out we have to divide fractions.
To divide a fraction you multiply the dividend by the reciprocal of the divisor.
My simple dictionary:
Dividend - The First number in a fractional problem
Divisor - The second number in a fractional problem
Reciprocal - a fraction flipped upside down so that the numerator is now the denominator. For example 3/2 = 2/3
Now that that is done let's look at the problem.
We have to divide 2 by 1/6 or multiply 2/1 by 6/1
To multiply a fraction we just multiply numerator by numerator and denominator by denominator.
2 x 6 = 12
1 x 1 = 1 (duh)
So, in conclusion, Val can create 12 slides in 2 hours :D
that was some really explicit stuff .-.
Answer:
72.57 kg
Step-by-step explanation:
1 lbs = 0.45359237 kg
160 lbs = 160 * 0.45359237 kg = 72.5747792 kg
72.5747792 kg round to the nearest hundredths is 72.57 kg
A. The answer is 6$ because 3 x 2 is 6
B. The answer is 12
