Answer:

The correct answer is the third option

Step-by-step explanation:

Have different slope but have the same y-intercept, so they have no solution.

y = 1/2x - 3

To graph this, the slope 1/2 which means go up once and to the right twice and b = -3, which means the y-intercept.

second equation:

y = -1/2x -3

To graph this, the slope -1/2 which means go down once and to the right twice and b = -3, which means the y-intercept.

How many significant digits are there in the measurement 84,000 kg

alex41 [277]

Answer:

$\boxed {\boxed {\sf 2 \ significant \ figures}}$

Step-by-step explanation:

According to the "rules" of significant figures, all the zeroes to the right of the final non-zero number are not significant, unless there is a decimal point.

We are given the measurement:

84,000 kg

If there was a decimal point (84,000.0 kg), then there would be 5 significant figures.

Since there isn't a decimal point, all 3 zeroes to the right of the number 4 aren't significant. The 8 and 4 are significant, so there are 2 significant figures.

If angle A has a measurement of 42° and is complementary to angle B, what's the measure of angle B?

KatRina [158]

The answer to the question is A. 48 degrees. In a complimentary angle, both of the angles have to add up to 90 degrees. For this case, with 42 degrees, the complimentary would be 48 degrees as they both add up to 90 degrees in the problem presented above.

The table below shows the cube roots of different numbers:

part A)

$\bf \begin{array}{|c|cccccc|ll} \cline{1-7} x&8&27&64&125&&x\\ \cline{1-7} y&\stackrel{\sqrt[3]{8}}{2}&\stackrel{\sqrt[3]{27}}{3}&\stackrel{\sqrt[3]{64}}{4}&\stackrel{\sqrt[3]{125}}{5}&&\sqrt[3]{x} \\ \cline{1-7} \end{array}~\hspace{10em}y = \sqrt[3]{x}$

part B)

f(x) = 10 + 20x

so if you rent the bike for a few hours that is

1 hr.............................10 + 20(1)

2 hrs..........................10 + 20(2)

3 hrs..........................10 + 20(3)

so the cost is really some fixed 10 + 20 bucks per hour, usually the 10 bucks is for some paperwork fee, so you go to the bike shop, and they'd say, ok is 10 bucks to set up a membership and 20 bucks per hour for using it, thereabouts.

f(100) = 10 + 20(100) => f(100) = 2010.

f(100), the cost of renting the bike for 100 hours.

How do I find the density? Harold is a woodworker and is interested in finding the density of two different types of wood. He bo

frosja888 [35]

Answer:

The density of the pine log is 0.2842 pounds per inch.

Step-by-step explanation:

To calculate the density of an object, you must divide its mass by its volume (radius times height). Thus, given that the pine log that has a 5-inch radius and is 30 inches long, while its weight is approximately 42.63 pounds, the following calculation must be performed to determine its density:

X = 42.63 / (30 x 5)

X = 42.63 / 150

X = 0.2842

Thus, the density of the pine log is 0.2842 pounds per inch.
