Answer:
C. 74 sqft
Step-by-step explanation:
The bottom has a surface area of 4ft * 5ft = 20sqft
Theres two 3ft x 5ft sides and two 3ft x 4ft ones.
2 * 3ft * 5ft + 2 * 3ft * 4ft = 2 * 15sqft + 2 * 12sqft = 30sqft + 24sqft = 54sqft
Total surface of the outside is thus
20sqft + 54sqft = 74sqft
Answer:
when you divide powers with the same base, you can just subtract the exponents
Answer:
5yz
Step-by-step explanation:
You multiply 5 by y and z
The equations presented in the choices above are all derived from the Pythagorean theorem. This states that the sum of the squares of the two shorter sides is equal to the square of the longest side which is also referred to as the hypotenuse.
If the sum of the squares of the shorter sides is smaller compared to the square of the hypotenuse then, the triangle is OBTUSE. The answer therefore to this item is letter A.
Answer:
7
Step-by-step explanation:
See the attached diagram with this answer.
If two straight lines cross a circle intersecting at two points then they can form a maximum of 4 regions within the circle, like the straight lines pq and rs form in circle c.
Now, another straight line mn is so placed that it forms the maximum number of separate regions in the circle.
Therefore, from the diagram, it is clear that there may be a maximum 7 separate regions formed by three straight lines intersecting the circle at two distinct points. (Answer)
