Answer: 31.25

Step-by-step explanation:

Okie dokie, so if something is marked up by 20% it means, it is 120% the original number right?

So we can convert 120% into 1.2 to make solving this problem easier. :)

So if we want to find the original number, all we have to do is divide 37.5 by 1.2.

This gets us 31.25.

A rectangle with sides 12 cm and 14 cm has the same diagonal as a square.
umka2103 [35]

Answer:

a=\sqrt{170}

Step-by-step explanation:

<u>Diagonal of a Square</u>

Given a square of length side a, the length of the diagonal is

D=\sqrt{2}a

The diagonal of a rectangle of sides x and y is

D=\sqrt{x^2+y^2}

The sides have lengths 12 cm and 14 cm, the diagonal is

D=\sqrt{12^2+14^2}

D=\sqrt{340}

Since this value is the same of the diagonal of certain square, we can say

\sqrt{2}a=\sqrt{340}

Dividing by \sqrt{2}

\boxed{a=\sqrt{170}}

Carl bought 24 daisies and roses. Daisies cost $0.25 each and roses cost $0.90 each. If
yuradex [85]

Answer:

Roses= $8.4

Daises= $15.6

Step-by-step explanation:

Let represent the daises and let r represent d roses

r + d= 24....equation 1

0.25r + 0.90d= 16.40.......equation 2

r= 25-d

Substitute 25-d for r in equation 2

0.25(25-d) + 0.90d= 16.40

6.25-0.25d+0.90d= 16.40

6.25+0.65d= 16.40

0.65d= 16.40-6.25

0.65d= 10.15

d= 10.15/0.65

d = 15.6

Sub 15.6 for d in equation 1

r+d= 24

r+15.6= 24

r= 24-15.6

= 8.4

Price of daises is $15.6

Roses is $8.4
