Lindsay earn $7.65 per hour.Her boss has promised her a 7% raise next month. If she works 40 hour per week, how much will she ea

zzz [600]

Answer:

She would make $327.60 each week after the raise

Step-by-step explanation:

First we need to find how much she will make per hour. We can do this by multiplying the per hour rate by the percentage of the raise.

$7.65 * 7% = $0.54

Now we add this amount to the previous hourly rate.

$7.65 + $0.54 = $8.19

Now that we have the new hourly rate, we multiply it by the number of hours that she works.

$8.19 * 40 = $327.60

1. Simplify 2/radical 5

cupoosta [38]

1. (2√5)/5
2. -44√7
3. 8√17
4. -6√3+12

For 1: Multiply the numerator and denominator by √5:
$\frac{2}{\sqrt{5}}\times \frac{\sqrt{5}}{\sqrt{5}}=\frac{2\sqrt{5}}{5}$

For 2: Simplify √112:
√112 = √(2*56) = √(2*2*28) = √(4*4*7) = 2*2√7 = 4√7
Now multiply by the -11 coefficient:
-11(4√7) = -44√7

For 3: Add the radicals as you would variables that are like terms.

For 4: Multiply by the conjugate. The conjugate of the denominator has the same values with the sign of the radical changed:
$\frac{6}{\sqrt{3}+2}\times \frac{\sqrt{3}-2}{\sqrt{3}-2}=\frac{6(\sqrt{3}-2)}{(\sqrt{3}+2)(\sqrt{3}-2)}
\\
\\=\frac{6\sqrt{3}-6*2}{\sqrt{3}*\sqrt{3}-2\sqrt{3}+2\sqrt{3}-2*2}
\\
\\=\frac{6\sqrt{3}-12}{3-4}=\frac{6\sqrt{3}-12}{-1}=-6\sqrt{3}+12$
