For each 24 mm of coloured fabric Gordon uses to make his curtains, he also uses 1.2 cm of white fabric. Express the amount of w
swat32

Answer:

1 : 2

Step-by-step explanation:

Given that,

amount of coloured fabric Gordon use to make his curtain = 24mm

amount of white fabric Gordon use to make his curtain = 1.2cm

To find,

ratio of the amount of white fabric to coloured fabric

1 cm = 10mm

1.2 cm = 1.2 * 10

           = 12 mm

<h3>Ratio</h3>

12 / 24

1 / 2

1 : 2

So, ratio of the amount of white fabric to coloured fabric is 1 : 2

Solve for x.<br> (x - 3)^2 -10 = 15
Brut [27]

Answer:

Step-by-step explanation:

Let's go:

(x - 3)^2 - 10 = 15 \\\ (x - 3)^2 = 15 + 10 \\\ (x - 3)^2 = 25 \\\ x - 3 = \sqrt{25} \\\ x - 3 = \pm 5

Solution #1:

x - 3 = 5

x = 5 + 3

x = 8

Solution #2:

x - 3 = - 5

x = - 5 + 3

x = - 2

I hope I helped you.

if alisson worked the times in the table and makes $9.32 an hour, how much was her gross pay this week
LenaWriter [7]
Hrs worked = 9.25 + 8.75 + 9 + 8.25 + 9 = 44.25 hrs. (44.25 - 40 = 4.25 hrs overtime) 
<span>40 hrs * $9.32 = $372.80 (Straight time) </span>

<span>$9.32 * 1.5 = $13.98 (Overtime rate) </span>
<span>4.25 (Overtime hrs.) x $13.98 (Overtime rate) = $59.42 (Overtime pay) </span>

<span>$372.80 + $59.42 = $432.22 (Total gross pay)</span>
