Answer:

  £592 for 16 boxes

Step-by-step explanation:

The classroom floor area is ...

  A = LW = (8.8 m)(2.2 m) = 19.36 m²

The cupboard floor area is ...

  A = (2.3 m)(2.1 m) = 4.83 m²

Then the total area to be covered is ...

  19.36 m² +4.83 m² = 24.19 m²

At 1.6 m² per box, the number of boxes required is ...

  (24.19 m²)/(1.6 m²/box) = 15.12 boxes

If we assume we can only purchase whole boxes, we need to purchase 16 boxes to cover the floor. The cost will be ...

  (16 boxes)(£37/box) = £592 . . . . cost of laminate to replace the floor

Janet has three times as many dimes as nickels and twice as many quarters as nickels. If she has $3.40 in all, how many nickels,
lord [1]
Let N be no. of nickles. Then N($.05)+3N($.10)+2N($.25)=$3.40.

Or

4 nickels = $0.20
12 dimes = $1.20
8 Quarters = $2.00

Total = $3.40

Find the average rate of change between f(-7) and f(-1) in the function f(x)=x^2+2x -8
Viktor [21]

Solve the equation by replacing x with -7 and then -1.

Then subtract the two to find the difference and divide that by the difference between -7 and -1.

f(-7) = -7^2 + 2(-7) -8 = 49 -14 -8 = 27

f(-1) = -1^2 + 2(-1) -8 = 1 -2 - 8 = -9

Difference between 27 and -9 = -36

Difference between -1 and -7 = -6

Rate of change = -36 /-6 = 6

equation: a/.5b=h

h=9

Step-by-step explanation:

a=1/2bh

divide both sides by 1/2b to get h alone

a/.5b=h

a/.5b=h

54/0.5(12)=h
