a) 5/7
b) 4459 cm cube
c) 2275 cm cube
Step-by-step explanation:
Step 1 :
a)
The Side AB (28 cm) has been scaled to side DE (20 cm)
Let x b the scale factor.
Then we have 28 *x = 20
=> x = 20/28 = 5/7
Hence the scale factor is 5/7
Step 2 :
b)
Given the height of the triangular prism is 15 cm
Volume = ( 1/2 ) * base* height of the triangle * height of the prism
= (1/2)* 21*28*15 = 4410 cm cube.
Step 3 :
c)
Given volume of the triangular prism with base ABC is 4459 cm cube
The scale factor is 5/7
Hence the volume of the prism with DEF as base is
4459 * (5/7)*(5/7) = 2275 cm cube.
Answer:0.8135
Step-by-step explanation:.5*.5*13/4
Answer:
Therefore 9th term of the geometric sequence is 
Step-by-step explanation:
Given first term(a) = 6
and common ratio = 
Therefore 9th term of the geometric sequence is
First the distributive property actually means "to share"
Second here's how you do it ...
the two numerators are multiplied , same with the denominator
4 x 10 and 25 x 1
this gets you 40/25 as an improper fraction but here is the simplified answer
1 3/5
