Parentheses are your friend when typing math equations anywhere. Use them to define function arguments (for example, sqrt, sin, cos, tan, log), exponents, numerators, and denominators. If an exponent, numerator, or denominator includes <em>any</em> math operation, it MUST be enclosed in parentheses.

3(√(125/5) -8) . . . . I have chosen an arrangement that gives a rational result

= 3(√25 -8)

= 3(5 -8)

= 3(-3)

= -9

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.

A person died leaving property worth Rs 4000.40. His widow got 0.125 of the property. His son got 0.4 of the remainder. What did

MakcuM [25]

Answer:

$2100.21

Step-by-step explanation:

If the widow gets 0.125 and the son gets 0.4, together they get 0.525, or 52.5%. If you multiply 4000.4 * 0.525, you get 2100.21, which is a little over half of 4000.

Math the equation to the solution type

Margarita [4]

Answer:

Step-by-step explanation:

1. 6x + 10 = 6x - 8

10≠-8

no solution

2. 6x + 8 = 2x - 6

4x + 8 = -6

4x = -14

x = -14/4= -7/2 one solution

3. 9x - 27 = 9x - 27

0 = 0 All real no. infinitely many solution
