Answer: 169.2cm
Step-by-step explanation:
From the question, we are informed that three equal-sized cardboard boxes are stacked on top of each other and that each box is 56.4 cm in height.
To get the combined height of the 3 stacked boxes, we multiply 56.4cm by 3. This will be:
= 56.4cm × 3
= 169.2cm
Step-by-step explanation:
Average speed (S) = 200 m/s
Time taken (t) = 2 .5 hours = 2.5 *60*60 = 9000 sec
Now distance travelled (d) = ?
We know
The distance travelled by a body per unit time is
speed so
S = d / t
200 = d / 9000
d = 9000 * 200
d = 1800000 meters.
The plane flies 1800000 meters.
1) set up a problem
you know you want to get an avg of 94 but how do you do avg in the first place. you add up the numbers then divde by the total number of numbers used lol
so

92.5 is the avg number for the last 3 tests
"x" is the 4th test score which we want to find out
"2" is the total number of numbers being added together
so now lets get x to one side
92.5+ x=94*2 (multiply 2 to both sides)
92.5+x=188
x=188-92.5 (subtract 92.5 from both sides)
x= 95.5 this is the score she need to make to avg 94%
2) you can draw a tree diagram. for example Flower1 branches off into 3 diff greens and then each of those greens branch off into 2 for with or with babies breath.
or you can simple multiply 4*3*2. you can do this because all choices are included with no restriction
your total number of options is 24
