Answer:

$\frac{2 \sqrt{5} x + \sqrt{2} x}{2}$

Step-by-step explanation:

$(3 \sqrt{20x} + \sqrt{18x} ) \div 6 \sqrt{x}$

$(3 \sqrt{4 \times 5x} + \sqrt{9 \times 2x} ) \div6 \sqrt{x}$

$(6 \sqrt{5x} + 3 \sqrt{2x}) \div 6 \sqrt{x}$

$\frac{6 \sqrt{5x} + 3 \sqrt{2} }{6} \times \sqrt{x}$

$\frac{2 \sqrt{5} x + \sqrt{2}x }{2}$

A company manufactures skateboards. Each skateboard requires 1 6/7 hours of labor to assemble and 2 1/2 hours of labor to finish

Assoli18 [71]

Answer: The total cost will be $156.85.

Step-by-step explanation:

Since we have given that

Time taken by labor to assemble the each skateboard is given by

$1\frac{6}{7}\ hours\\\\=\frac{13}{7}\ hours$

Time taken by labor to finish and stain each skateboard is given by

$2\frac{1}{2}\ hours\\\\=\frac{5}{2}\ hours$

Cost of labour to the company per hour = $36.00

According to question,

We will use "Distributive Property":

$a\times (b+c)=a\times b+a\times c$

$36(\frac{13}{7}+\frac{5}{2})\\\\=36\times \frac{13}{7}+36\times \frac{5}{2}\\\\=\frac{468}{7}+18\times 5\\\\=\frac{468}{7}+90\\\\=\frac{468+630}{7}\\\\=\frac{1098}{7}\\\\=\$156.85$

Hence, the total cost will be $156.85.

Write an equation in slope-intercept form for the line with slope 8 and y-intercept -8.

Fofino [41]

Answer:

y = 8x - 8

Step-by-step explanation:

y = mx + b is slope-intercept form

m - slope

b - y-intercept

so if you plug in 8 for m and -8 for b you'll get

y = 8(m)x - 8(b)

Hope this helps!!
