Answer:
90
Step-by-step explanation:
it is 90 because in the first slot there can be any 10 numbers and in the second slot the set can contain any of the remaining 9 numbers and then we can multiply these two numbers together to find the total amount of sets.
hope this helps :)
Alright, if the original scale was 1 inch = 8 miles, and Dale's house to his school are 1 1/2 inches apart, let's find the amount of miles.
Here's a fast way. 1 inch is 8 miles, and half of 8 equals 4 miles, which is 1/2 of an inch., 8 + 4 = 12 miles.
So if his house and the school were 12 miles apart, and we we're using the 1 inch. = 6 miles scale, then it'd be 2 inches on the map.
How?
If 1 inch. = 6 miles
x inches = 12 miles
12/6 = 2
2 inches = x
Answer:
4.35pm is the later time, both buses were together back at the depot.
Reasons;
As bus b did not return his return route until 35 minute after departure.
We can say this was a return route taking 35 minute as the question does not point out length of time getting back. We therefore state it is a return route in the workings to explain how we found the answer.
Step-by-step explanation:
4.00 + 0.35 = 4.35 = b
4.00 + 0.15 = 4.15 = a
4.35 is the later time.
Answer:
3n + 8 ≤ 32
Step-by-step explanation:
You multiply the 3 and the n together then add the 8 and it can't be more than 32 but it can be equal to 32
let
i= Interest
p= Principle
r= rate
t= time
data given
i= $2520
p= $7000
t= 4years
r= ?
From the formula
i= prt
we make 'r' the subject by multiplying by pt both sides
i/pt=prt/pt
i/pt=r
its the same like
r=i/pt
r=$2520/($7000×4)
r=$2520/$28000
r=3/350
r=0.09%
therefore the interest rate is 0.09%
