7 M
--- = ----
9 27
cross multiply (7*27=189) and divide (189/9=21)
M = 21
Hi there!
For number 1 it shows that the last two blanks would be 8/8 and 4/4 since adding 1/8 would be 8/8 and adding 1/4 would be 4/4.
For number 2, it would be 3/6 or a half. It wants to have another equivalent to 3/6 and with dividing 3 for each side, it would be 1/2.
Answer:
85 cm²
Step-by-step explanation:
The base is a square with side length 5 cm. The area of this base is
A = s² = (5 cm)² = 25 cm².
If the slant height of each lateral face of the pyramid is 6 cm, then we can find the area of each such face using the area-of-a-triangle formula,
A = (1/2)(base)(height), which here is
A = (1/2)(5 cm)(6 cm) = 15 cm² per lateral side.
The total area of these sides is 4(15 cm²) = 60 cm².
Then the total surface area of the pyramid is A = 60 cm² + 25 cm² = 85 cm².
2.46875 in a fraction form would look like this:
2.46875 =
= 2 46875/100000 =
= 2 9375/20000 =
= 2 1875/4000 =
= 2 375/800 =
= 2 75/160 =
= 2 15/32
I just kept simplifying it by dividing both numerator and denominator by 5 until I got its simplest form.
