Answer:
300
Step-by-step explanation:
15 * 20 = 300
she spent 3/5 * 300 = 180
and saved 2/5 * 300 = 120
Answer:
49
Step-by-step explanation:
n is 3/7 of total fruit
n=21 apples
Here they are just telling us that the apples make up a total of 3/7 percent of the total fruit in the box. So to find the total amount of fruit from this information we just simply take the n number of apples and divide that by the percent that it represents. So basically just this;
n=21 and (n)/(3/7)=total fruit
(21)/(3/7)=21*7/3=147/3=49 total fruit and 21apples make up (3/7)% of the total fruit in the box.
Hope this helped some. Any questions please feel free to ask. Thanks!
Write an equation to show all elements:
Cost of 4 lots of b (beads) + cost of 4p (pendants) = $18.80
Put values in;
9.29 + 4p = 18.80
4p = 18.80 - 9.20
4p = 9.60
p = 2.40 cost of each pendant
Sinx=1/2
sin30=1/2
therefore x=30 degree
30% because as a decimal it would be written as .30 and that is greater then .03
