Bob has some 10 lb weights and some 3 lb weights. Together, all his weights add up to 50 lbs. If x represents the number of 3 lb

olga2289 [7]

Answer:

3x = 50 - 10y

Step-by-step explanation:

Here, x represents the number of 3 lb weights and y represents the number of 10 lb weights,

So, total weight of 3 lb weights = 3x

And, the weight of 10 lb weights = 10y

Total weight of all his weights = 3x + 10y

According to the question,

Total weight = 50 lb,

⇒ 3x + 10y = 50

Or 3x = 50 - 10y

Which is the required equation.

Second option is correct.

Find the volume of the cylinder in terms of pi h = 6 in. and r = 3 in. A 54π in.3 B108π in.3 C324π in.3 D 27π in.3

Orlov [11]

Answer:

Option A. $54\pi\ in^{3}$

Step-by-step explanation:

we know that

The volume of the cylinder is equal

$V=\pi r^{2}h$

where

r is the radius of the base of cylinder

h is the height of the cylinder

we have

$r=3\ in$

$h=6\ in$

substitute

$V=\pi (3)^{2}(6)$

$V=54\pi\ in^{3}$

Answer:

Step-by-step explanation:

This is a right triangle trig problem. The base of the right triangle is the distance that Donna if from the flagpole; the flagpole is the side opposite the reference angle which was given as 26, and we are looking for the height of the flagpole, h. The trig ratio that uses the side opposite over the side adjacent is the tangent ratio, specifically:

$tan26=\frac{h}{123}$ and

123tan(26) = h so

h = 60.0 rounded to the nearest tenth. But that is only the height from her line of vision and up, not the whole height. In order to find the whole height, we have to add in her height up to her line of vision which is 5.3 feet. Therefore, the height of the flagpole is

60.0 + 5.3 = 65.3 feet.
