17*8=(10+7)*8
Use the distributive property
17*8=(10*8)+(7*8)

You have to multiply the number outside the bracket with each of the numbers within it
Example 5(2+10)
Then (5*2)+(5*10)

On a number line, point D is at -3, and point E is at 6. The point F lies on DE. The ratio of DF to FE is 2:3. Where does point
expeople1 [14]

Answer: point F is at <u>   0.6   </u> on the number line

=============================================================

Explanation:

The ratio 2:3 scales up to 2x:3x for some positive real number x.

This means the distance from D to F is 2x units, and the distance from F to E is 3x units. Combine those two smaller distances to get 2x+3x = 5x to represent the full distance from D to E.

D is at -3 and E is at 6. This is a distance of 9 units since |-3-6| = |-9| = 9

Set this equal to the 5x from earlier and solve

5x = 9

x = 9/5

x = 1.8

This leads to 2x = 2*1.8 = 3.6

Therefore, we'll move 3.6 units from -3 to -3+3.6 = 0.6 which is the location of point F on the number line.

Notice that from 0.6 to 6 is 5.4 units and that 3x = 3*1.8 = 5.4 matches up to help confirm the answer.

Evgen [1.6K]

Answer:

16 responses

Step-by-step explanation:

we know that

A geometric sequence, is a sequence of numbers where each term after the first is found by multiplying the previous one by a fixed, non-zero number called the common ratio.

a_n=r^{n-1}

where

a_n----> n^{th} term of the sequence

r ---> is the common ratio

a ---> the first term of the sequence

a=50\\r=100\%-10\%=90\%=90/100=0.90

substitute

a_n=50(0.90)^{n-1}

For n=12

substitute

a_n=50(0.90)^{12-1}=16
