Answer:
Step-by-step explanation:
10,12,13,20, 21,
6 granite, 3 marble, 14 sandstone, 1 slate
ratio of sandstone to marble
how many sandstone does she have .....14
how many marble does she have......3
so the ratio would be : 14/3 or 14:3, or 14 to 3
Answer:
324 and 144
Step-by-step explanation:
We require
a₁, a₂, a₃, a₄
where a₂ and a₃ are the required geometric means
The n th term of a geometric sequence is
= a₁
where a₁ is the first term and r the common ratio
Here a₁ = 729 and a₄ = 64, thus
729(r³) = 64 ( divide both sides by 729 )
r³ =
( take the cube root of both sides )
r =
=
, then
a₂ = 729 ×
= 81 × 4 = 324
a₃ = 324 ×
= 36 × 4 = 144
Thus
729, 324, 144, 64

Answer:
1) 6/4 or 1 1/2, so you fill in 6 of the lines in the model
2) 8/6 or 1 1/3, so you need to fill in 8 of the lines in the model
