Answer:

40%

Step-by-step explanation:

The probability of the arrow landing on the green section is a 40% chance

This is because there are only 3 sections where one is 50 and the other is 10

To find the green we can create an equation, where x = green section

50 + 10 + x = 100

The equation equals 100 because that's the highest the percentage will go in probability, unless we were told otherwise

60 + x = 100

x = 100 - 60

x = 40

Mary makes biws for floral arrangements she uses 1/8 yard of ribbon for each bow how many bows can she make from two spools that
olga2289 [7]
STEP 1:
Calculate total amount of ribbon
= 2 spools * 24 yards each
= 48 yards total

STEP 2:
Divide total yards (48 yards) by portion size (1/8 yard)

= 48 ÷ 1/8
to divide fractions, we multiply by the reciprocal/inverse of 1/8
= 48 * 8/1
= 48 * 8
= 384 bows

ANSWER: She can make 384 bows.

Hope this helps! :)
