Answer: A) 21

Step-by-step explanation:

From the given figure, we can see that angles 64^{\circ} and (3x+1)^{\circ} are vertically opposite angles.

Since, vertically opposite angles are equal, therefore we have

64^{\circ}=(3x+1)^{\circ}\\\\\Rightarrow64=3x+1\\\\\text{Subtract 1 on both sides, we get}\\\\\Rightarrow3x=63\\\\\text{Divide 3 on both sides, we get}\\\\\Rightarrow x=21

Hence, the value of x = 21.

Suppose that you need to build as many chairs as possible. Each chair requires one seat, one back, and four legs. If you have 12
GrogVix [38]

Answer:

  legs limit the number of chairs that can be built

Step-by-step explanation:

The maximum number of chairs that can be built will be the minimum of the number of parts divided by the number of parts needed for each chair, as computed across the different kinds of parts required.

  seats: 12 available, used 1 per chair: 12/1 = 12 chairs possible

  backs: 15 available, used 1 per chair: 15/1 = 15 chairs possible

  legs: 44 available, used 4 per chair: 44/4 = 11 chairs possible

The maximum number of chairs that can be built will be the minimum of 12, 15, and 11. That is, 11 chairs can be built, limited by the number of available legs.

The radius of a sphere is increasing at a rate of 5 mm/s. How fast is the volume increasing (in mm3/s) when the diameter is 40 m
jeka94

9514 1404 393

Answer:

  8000π mm^3/s ≈ 25,133 mm^3/s

Step-by-step explanation:

The rate of change of volume is found by differentiating the volume formula with respect to time.

  V = 4/3πr^3

  V' = 4πr^2·r'

For the given numbers, this is ...

  V' = 4π(20 mm)^2·(5 mm/s) = 8000π mm^3/s ≈ 25,133 mm^3/s

_____

<em>Additional comment</em>

By comparing the derivative to the area formula for a sphere, you see that the rate of change of volume is the product of the area and the rate of change of radius. This sort of relationship will be seen for a number of different shapes.

Simplify write in scientific notation 0.5(8x10^5)
Oksi-84 [34.3K]
10 to the 5th power means 5 times zero, place 8 before that and it will be 800000 then multiply with 0.5 it will be 400000. In scientific notation it will be like 4x10 the 5th power.
