Answer:
8765.25
Step-by-step explanation:
p=$7540
r=6.5%
t=2.5
simple interest formula= (p*r*t)/100
(7540*6.5*2.5)/100=1225.25
total amount= p+S.I
=7540+1225.25
=8765.25
thankyou^^
Because there are less pieces the whole is split up into. For instance,
if you have 1 bag of cookies, you would get more cookies per person if
it was split between 2 people than if it was split between 10, because each person
gets more of the whole, and there's less people to split up that whole.
since you have an equal amount of pieces from each, the whole that was
split into the least pieces, or the number with the smaller denominator will be larger since the pieces will be larger
Answer:
y=447.3 pounds
x= 297.3 pounds
Step-by-step explanation:
Step one:
given data
Tea A costs $9 per pound and
Tea B cost $6 per pound.
let the number of pounds of Tea A be x
and for Tea B be y pounds
The total cost of the mixture = $8 per pound
hence
9x+6y=8---------1
The total weight of the mixture
150 pounds
x+y=150-----------2
Step two:
9x+6y=8---------1
x+y=150---------2
from eqn 2 x=150-y
put x= 150-y in eqn 1
9(150-y)+6y=8---------1
1350-9y+6y=8
1350-8=9y-6y
1342=3y
divide both sides by 3
y= 1342/3
y=447.3 pounds
put y= 447.3 in eqn 2
x+447.3= 150
x= 150-446=7.3
x= -297.3
x= 297.3 pounds
Answer:36
Step-by-step explanation:
for every 7 students there are 4 girls, so for every 84 there must be 48
7*12=84
4*12=48
so, in all 84 students there are 48 girls
so amount of boys=84-48=36
there are 36 boys
