Answer:
4 batches
Step-by-step explanation:
one batch calls for:
3/4 PB
1 1/2 cup SG
1 EGG
3/.75(3/4)= 4
9/1.5(1 1/2)=6
5/1= 5
The maximum number of batches she can make before running out of ingredients is 4
Answer:
Step-by-step explanation:
12,800 written as 1.28 x 104 in scientific notation
Answer:
Both of the equations are right because if you take s=4p, then reverse it, p=1/4 of s because 4 of p is equal to s so s/4 = p
Let's call your speed "a"
her walking speed is then "2a"
and her friend's scooter speed is 10 a
let's also call the distance you need to walk "d"
so the time (t)you need is:
d/t=a
t=d/a
and her time is:
t=

(half a distance with the speed of 2a and half a distance (d/2) with the distance of 10 a
now we count (we know that her time is 30 minutes)
30=

//multiply by 20a
600a=

600a=6d/divide by 6
100a=d
Now, in order to calculate your time we need to calculate:
t=d/a
but we know how much is d now!
t=

=100
which means that you need 100 minutes, or 1 h 40 minutes!!!
Answer:
1 .i think it is d
