Divide. Give the quotient and remainder. 426÷8
Anna007 [38]
We can start to solve this problem like how we solve any division problem. Since 8 doesn't go evenly into 4, we can move one digit to right, giving us the number 42. 42 divided by 8 is 5, so we write 5 on top of the division bar and keep working. Since 42-40 is 2, there's still 2 remained after doing that. Now we can bring down the 6, turning the number into 26. 26 divided by 8 is 3 remained 2, so we can put the three next to the 5. Since we have two remained and no more numbers, that means that the answer to 426/8 is 53 remainder 2.

danny has a trianglular pyramid all triangles are conguent what is the surface area?​the height is 6in and the width is 5in
Gre4nikov [31]

Answer: The answer is 60 square inches.

Step-by-step explanation:  Given that Danny has a triangular pyramid where all the four triangles are congruent. The height and base of one triangle are 6 inches and 5 inches respectively. We are to find the surface area of the pyramid.

The area of one triangle is given by

A=\dfrac{1}{2}\times\textup{base}\times\textup{height}=\dfrac{1}{2}\times 5\times 6=15~\textup{sq. inches}.

Since the pyramid consists of four congruent triangles, so the surface area of the pyramid will be

S=4\times A=4\times 15=60~\textup{sq. inches}.

Thus, the answer is 60 sq. inches.
