Answer:
5
Step-by-step explanation:
The trainer uses 75 inches of tape on 1 ankle, this can be represented in the following table:
Inches of tape ankles
75 ⇒ 1
what we need to know is how many anles can be taped with 10 meters of the tape. For that first we need to <u>convert those 10 meters to inches </u>
since 1 meter = 39.3701 inches
thus 10 meters = 10*39.3701inches
10 meters = 393.701 inches
If we call the unknown amount of ankes x, and we update our table we get the following :
Inches of tape ankles
75 ⇒ 1
393.701 ⇒ x
And we solve this problem by the <u>rule of three</u>: multiply cross quantities on the table and divide by the remaining amount like so:
x = 393.701 * 1 / 75
x= 393.701 / 75
x = 5.25
which we must round down to only 5 complete ankles.
the trainer can tape 5 ankles with the 10 meters of tape.
3 divided by 85 is:
3/85
or in decimal form
0.03529411764
Answer:
Step-by-step explanation:
<u>Factor x³ + 2x:</u>
1. <u>The common factor is x, then</u>:
- 2 + k = 0 ⇒ k = -2 (all the rest are divisible by x)
2. Factor x² + 2 is not linear therefore we discard it.
