Sarah has $12.45 in quarters and nickels. She has 39 more nickels than quarters.
How many of each coin does she have?
Answers
Answer:
There are 14 nickes, 24 dimes and 48 quarters
Step-by-step explanation:
let x represent the number of nickels.
As she has 10 more dimes than nickels, the number of dimes is x + 10.
As she has twice as many quarters as dimes, the number of quarters is 2(x + 10)
the total value is $15.10, so I get an equation:
0.05x + 0.1*(x + 10) + 0.25*2(x + 10) = 15.10
0.05x + 0.1x + 1 + 0.5x + 5 = 15.10
0.65x = 9.1
x = 14
x + 10 = 24
2(x + 10) = 48

The ideal length of a particular metal rod is 25.5 cm. The measured
length may vary from the ideal length by at most 0.025 cm. Find the
range of acceptable lengths for the rod.
Answers
Answer:
Option: D is the correct answer.
D) 20.455 <= X <= 20.545
Step-by-step explanation:
We are given The ideal length of a particular metal rod is 20.5 cm.
It is given that:
The measured length may vary from the ideal length by at most 0.045 cm.
By atmost we mean either less than or equal to that amount but not more than that.
It means that:
|X-20.5|≤ 0.045
⇒ -0.045 ≤ X-20.5 ≤ 0.045
⇒ -0.045+20.5 ≤ X ≤ 20+0.045
⇒ 20.455 ≤ X ≤ 20.545.

Find the measures of two supplementary angles, <M and <N, If M=6x+3 and m<N=2x-7
Answers
9514 1404 393
Answer:
M = 141°, N = 39°
Step-by-step explanation:
Supplementary angles have a total measure of 180°, so ...
M + N = 180
(6x +3) +(2x -7) = 180
8x = 184 . . . . . add 4, simplify
x = 23 . . . . . . . divide by 8
∠M = 6·23 +3 = 141°
∠N = 2·23 -7 = 39°

Shelly runs 2.5 miles in 18 minutes. what is her mile time in minutes.
Answers
Answer:
7.2315656
Step-by-step explanation:
Let's agree that 2.5 miles : 18 minutes is the ratio between the amount of distance and the amount of time spent running. If we spent 2x as many minutes running, Shelly would run 5 miles. In the same context, let's find the amount of distance covered in 18 minutes.
18 × (60/18) = 60
We multiply 60/18 because 60/18 = 60 × (1/18), and the (1/18) cancels with the 18 so we are left with the numerator, 60.
2.5 : 18
Now, we have to multiply 60/18 on both sides!
2.5 × (60/18) : 18 × (60/18) = 60
2.5 × (60/18) = 8 and 1/3 miles
