Answer:

The median amount of money raised is $5.00

Step-by-step explanation:

To find the median amount of money raised, we will follow the steps below:

First, arrange the data giving in ascending order. That is

$6.00, $7.00, $4.00, $5.00, $3.00

We will arrange it in ascending order, hence

$3.00, $4.00, $5.00,  $6.00, $7.00

The median is the middle number, we will now proceed to take the middle number.

The middle number is $5.00

Therefore, the median amount of money raised is $5.00

Ajar holding 36 coins, only nickels and quarters, is worth $6.20. There are eight more quarters than there are nickels. How many
Nonamiya [84]

Answer:

  14

Step-by-step explanation:

Let n represent the number of nickels. Then the number of quarters is 36-n. The difference is ...

  (36-n) -n = 8 . . . . . 8 more quarters than nickels

  18 -n = 4 . . . . . . . divide by 2

  14 = n . . . . . . . . add n-4 to both sides

There are 14 nickels in the jar.

<em>Additional comment</em>

The problem supplies more information than is needed for a solution. You can work this as a "sum and difference" problem, as we have above, or you can work it as a "mixture" problem where the total coin value comes into play. Any two of the three given relations will give a solution.

  n + q = 36 . . . . . . . number of coins

  5n +25q = 620 . . . value of coins (in cents)

  q -n = 8 . . . . . . . . difference in number of coins

If ƒ(x ) = 3x + 1 and ƒ -1 = , then ƒ -1(7) =
Elden [556K]
F(x) = 3x + 1

let f(x) = y

y = 3x + 1

y - 1 = 3x

3x = y - 1

x = (y - 1)/3

From y = f(x),  x = f⁻¹(y) 

<span>x = (y - 1)/3
</span>
 f⁻¹(y)  = (y - 1)/3

f⁻¹(7)  = <span>(7 - 1)/3 = 6/3 = 2

</span>f⁻¹(7)<span> = 2</span>

Giovanna,Frances, and their dad each carried a ten pound bag of soil into the back yard. After putting soil in the first flower
Greeley [361]
First find the common denominator
5/8=25/40
2/5=16/40
3/4=30/40
Next you can cross multiply
25/40=x/10 pounds
16/40=x/10 pounds
30/40=x/10 pounds
First
25(10)/40= 6.25 pounds
16(10)/40= 4pounds
30(10)/40= 7.5 pounds
These are the amounts that were left in the bag

10-6.25=3.75
10-4=6
10-7.5=2.5

3.75+6+2.5= 12.25

All together they put 12.25 pounds of soil in the flower bed

M is between L and N. LM = 7x-1, MN = 2x +4, and LN = 12. find the value of ‘x’ an determine if M is a bisector.
Sholpan [36]

LM + MN = LN

7x - 1 + 2x + 4 = 12

9x + 3 = 12

9x = 12 - 3

9x = 9

x = 9/9

x = 1
