Answer:
768 m^2
Step-by-step explanation:
<u>Separate the shapes</u>
We can first separate the triangular pyramid from the rectangular prism.
We can calculate them separately.
<u>Calculate</u>
The volume of the triangular pyramid is the base multiplied by the height divided by 3. The base of the pyramid has the same base as the prism so:
8 * 8 = 64
Then we need the height which is 6 so:
64 * 6/3 = 64 * 2 = 128 m^2
Then we calculate the volum of the prism; the formula for that side times side time side:
8 * 8 * 10 = 640 m^2
The total volume is them added up:
128 + 640 = 768 m^2
Answer:
Harry swims at 1.6 laps per minute and Larry swims at 1.8 laps per minute. Henry swims at a slower rate than Larry.
Step-by-step explanation:
i dont know for sure if this is right or not but i think it is. i mean for Henry the only number i have is 1.6 and so if that is going to be multiplied by x which is his minutes i would guess that that is the rate he is swimming at per minute. and as for larry, i took 4.5 (which is his laps) and divided it by 2.5 (which is his time) to get how many laps per minute he swims. i got 1.8. 1.6 is slower than 1.8 so therefore, i concluded that harry swam at a slower rate than larry.
Answer:
x = 129
Step-by-step explanation:
x = 129 because of alternate interior angles
Answer:
A Poisson distribution, with λ=5.3

Step-by-step explanation:
For this type of random variables, a Poisson distribution is the most adecuate.
If the number of occurrences in ten minutes is 5.3, we can define the parameter λ=5.3 and the probability function as:
