Answer:
Perimeter= 12 feet Area= 6 feet (squared)
Step-by-step explanation:
Perimeter= Adding all the sides together, that means it is 3+4+5= 12 feet
Area= Hight times base divided by 2. Because hight times base is area of a rectangle, and a right triangle (and all other triangles) is half of it. Because it is a right triangle, its hight must be 3 or 4, and base also 3 or 4. But no the same number twice, so 3*4=12, 12/2=6 feet (squared).
I hope that helped! =)
Answer:
square kilometers
Step-by-step explanation:
The surface area of a sphere can be found using the formula
. Since the diameter is 3500 km then its radius is half of this. 3500 divided in two is 1,750 units. Substitute r=1,750.

The surface area of the moon is about 38,465,000 square kilometers. Write this is scientific notation using base. 
Answer: kindly check explanation
Step-by-step explanation:
Given that number of dolphins = 800 with different length and ages
Median length = 5.8 feets
The median may be explained to be a measure of center which gives the information as regards around the middle or midpoint of a dataset. According to the information above, the median length if the 800 dolphins is 5.8 feets, this means the 50th percentile value is 5.8 feets and hence, Half of the dolphins sampled have a length which is greater than 5.8 feets and the other half has a length which is less than 5.8 feets.
Answer: c
Step-by-step explanation: if you draw second function you'll see they are the same so slop is also the same(0.5)
2 because 1 and 1 half x 2 is 3 and that is two whole.
3/4 is hald of a whole so it cant count
