fluorescent powder comes in 20 G vials with 12 vials in a set, each vilal a different color. so if I order 3 sets I will have 3

Anna007 [38]

First you need to know how many cups of powder you are going to need for the 496 cups of paint you already have

$\begin{gathered} 1\text{ CUP POWDER}\Rightarrow5\text{ CUP PAINT} \\ x\text{ CUP POWDER}\Rightarrow496\text{ CUP PAINT} \end{gathered}$

We write this as a ratio

$\begin{gathered} \frac{x}{496}=\frac{1}{5} \\ x=\frac{496}{5} \\ x=99.2 \end{gathered}$

for the 496 cups of paint you will need 99.2 cups of powder.

Continue by seeing how may grams there are in 99.2 cups

$\begin{gathered} 60g\Rightarrow0.2536\text{ CUPS POWDER} \\ x\Rightarrow99.2\text{ CUPS POWDER} \end{gathered}$

write it as a ratio and solve for x again.

$\begin{gathered} \frac{x}{99.2}=\frac{60}{0.2536} \\ x=23470.03155 \end{gathered}$

now find how many vials you will need

$\begin{gathered} 1\text{vial}\Rightarrow20g \\ x\Rightarrow23470.03155g \end{gathered}$

write the ratio and solve

$\begin{gathered} \frac{x}{23470.03155}=\frac{1}{20} \\ x=\frac{23470.03155}{20} \\ x=1173.5\approx1174 \end{gathered}$

If each sets comes with 12 sets, write the ratio and find the number of sets you will need

$\begin{gathered} 1\text{set}\Rightarrow12vials \\ \text{xsets}\Rightarrow1174vials \end{gathered}$ $\begin{gathered} \frac{x}{1174}=\frac{1}{12} \\ x=\frac{1174}{12} \\ x=97.83\approx98 \end{gathered}$

you will need 98 sets for this amount of paint.

Dan pays £220 per week in rent.

____ [38]

Answer:

225.5

Step-by-step explanation:

220 + (2.5% × 220) =

220 + 2.5% × 220 =

(1 + 2.5%) × 220 =

(100% + 2.5%) × 220 =

102.5% × 220 =

102.5 ÷ 100 × 220 =

102.5 × 220 ÷ 100 =

22,550 ÷ 100 =

225.5

Answer:

x = -2.32, 10.32 to the nearest hundredth.

Step-by-step explanation:

x^2 - 8x - 24 = 0

x = [ - (-8) +/- sqrt (((-8)^2 - 4*1*(-24)] / 2

= 4 +/- sqrt160/2

= 4 +/- 6.3245

= -2.32, 10.32.
