A discount voucher offering 15% off is used to pay a bill. After using the voucher, the bill is reduced to £36.72.

Elena-2011 [213]

We can use the is/of=p/100 method for this problem. Since it's 15% off, this would mean that the bill is 85% of what it was initially. Plug the values into the is/of=p/100 formula.

36.72/x = 85/100

Solve for x.

x=36.72/0.85

x=43.2

So, the bill was $43.20 before applying the voucher discount of 15% off.

Find the measure of line KM. A. 14 B. 9 C. 12 D. 10

HACTEHA [7]

$\\ \sf\longmapsto \dfrac{3}{x-4}=\dfrac{6}{x-5}$

$\\ \sf\longmapsto 3(x-5)=6(x-4)$

$\\ \sf\longmapsto 3x-15=6x-24$

$\\ \sf\longmapsto 3x-6x=-24+15$

$\\ \sf\longmapsto -3x=-9$

$\\ \sf\longmapsto x=\dfrac{-9}{-3}$

$\\ \sf\longmapsto x=3$

$\\ \sf\longmapsto KM=3+6=9$

What is the ratio of red to blue squares in its simplest form? 14 red 4 blue

zlopas [31]

Simplest Form: $7 : 2$

How to Simplify a Ratio A : B when A and B are both whole numbers:

List the factors of A
List the factors of B
Find the greatest common factor of A and B, GCF(A, B)
Divide A and B each by the GCF
Use the whole number results to rewrite the ratio in simplest form

Try to reduce the ratio further with the greatest common factor (GCF).

The GCF of 14 and 4 is 2

Divide both terms by the GCF, 2:

14 ÷ 2 = 7

4 ÷ 2 = 2

The ratio 14 : 4 can be reduced to lowest terms by dividing both terms by the GCF = 2 :

14 : 4 = 7 : 2

Therefore:

14 : 4 = 7 : 2
