Answer:
3 steps per second.
Step-by-step explanation:
Find the Unit Rates of each going up and down:
--> 30/6 unit rate is 5 steps per second.
--> 30/15 unit rate is 2 steps per second.
Now subtract them to get the amount if the elevator wasn't moving:
--> 5-2= 3.
- y^6/5x^3z^2, Answer & Steps below:
So first multiply the whole numbers.
6x2=12
Now multiply 6 and 7. When multiplying a fraction like this, do the numerator ONLY. So it ends up being 42/10. That can be turned to a mixed number. To do that, find out how many times 10 can go into 42. The highest whole number is 4.
10x4=40 and there's 2 left over. So make it 2/10 which can be simplified to 1/5
Now add.
12+4=16+1/5= 16 1/5
Answer:
54.3
Step-by-step explanation:
substitute the given values for v and w into the expression
(8.1 × 3 ) + (7.5 × 4 )
= 24.3 + 30 = 54.3
Now, let’s find the unit
of the given numbers.
Food A = contains 150 calories in every ¾ serving
Food A
=> 150 / 3 = 50
=> 150 + 50 = 200 calories
=> 150 = ¾ calories and 50 = ¼ calories
Food B = contains 250 calories in every 2/3 of serving
Food B
=> 250 / 2 = 125
=> 250 – 125
=> 375 calories
=> 250 = 2/3 calories 125 = 1/3 calories
Thus, Food A has fewer calories.
