Regular quadrilateral pyramid with base edge b=55 mm and lateral edge l=7 cm. Find the sum of all edges

Answers

Answer 1

Answer: The correct answer is 50 cm or 500 mm. There are 4 base edges and 4 lateral edges, so just multiply the number for both edges by 4 and add. The question threw a curveball at us by giving us two units of measurement, millimeters and centimeters, but since we know that there are 10 millimeters in a centimeter, we can just divide 55 by 10 to get 5.5.

5.5 x 4 = 22
7 x 4 = 28
28 + 22 = 50

If it helps, you can draw the figure and label the edges. Remember that the lateral edge of a quadrilateral pyramid is the slanted line leading up to the top of the pyramid, and that the base edges are the sides of the quadrilateral on the bottom.

Hope this helps!

the answer is 2 and 5/6

Whole numbers 1 and 1 are added.

Since the two fractions have the same denominator, we can add the numerators together, which is how the 5/6 fraction is created.

Thank You!

Answers

In this question we can seethat there is one unknown variable named “y” and one equation. So it isabsolutely possible to find the correct value of the unknown variable “y”. Nowlet us check the equation that is given and solve it correctly.
y - 18 = 10
y = 10 + 18
= 28
So the value of the unknown variable “y” is 28. I hope thisis the answer you were looking for and the procedure is clear to you.

To solve for y we will use the INVERSE OPERATION of subtraction which is addition. Lets do it:-

y - 18 = 10
10 + 18 = y
10 + 18 = 28
y = 28

CHECK OUR WORK:-

28 - 18 = 10
We were RIGHT!!!

So, y = 28.

When 2 fractions refer to the same whole explain why the fraction with a lesser denominator has larger pieces than the fraction with a greater denominator

Answers

The denominator tells how many pieces the whole is broken into. So a denominator of two tells you that the whole is broken into two pieces. A denominator with 8 tells you that the whole is broken into eight pieces. Think of a pie. if it is cut into two pieces that's two halves. if it is cut into 8 pieces then that is eighths.
