the answer to this is

<h2><u><em>0.04(30h) is the part.</em></u></h2><h2>please mark brainliest :)</h2>

0.04(30h) is the part. Because 0.04 represents 4%, we know that it should be the tax rate. 30h represents the cost for every hour, so we know that that's not the correct answer.

My homework says, "Does the graph represent a proportional relationship? Why or why not? You MUST explain to get credit."

VMariaS [17]

Answer:

No, the graph does not represent a proportional relationship. It is a straight line, but it does not intersect the point (0, 0). ... It's not proportional because the line does not cross through the origin. Therefore the ratio of x to y will be different for two different points on the line.

What is the value of x ???

k0ka [10]

Answer:

D. $2\sqrt {133}$

Step-by-step explanation:

${x}^{2} = {18}^{2} + ( {12}^{2} + {8}^{2} ) \\ \\ {x}^{2} = 324 + (144 + 64) \\ \\ {x}^{2} = 324 + 204 \\ \\ {x}^{2} = 528 \\ \\ x = \sqrt{532} \\ \\ x = \sqrt{4\times 133} \\ \\ x = 2\sqrt {133}$

Jake plans to use a ramp to make it easier to move a piano out of the back of his truck. The back of the truck is 83 centimeters

storchak [24]

Answer:

134.4 centimeters

Step-by-step explanation:

This question is asking us for a missing leg on the triangle, lets call it x. Using the Pythagorean theorem (a²+b²=c²), we can figure out what value is missing (either a or b, they are interchangeable).

replace the values in the equation.

83²+x²=158²

get rid of the exponents.

6,889+ x² = 24,964.

subtract 6,889 from 24,964.

x²=18,075.

find the square root on both sides of the equation.

x=134.4432966.

I am assuming you want this rounded to the nearest tenth.

134.4 is your answer.
