Answer:
174 rpm
Step-by-step explanation:
The question says that the speed is inversely proportional to the length. Thus, Inverse means, as the diameter increases, the speed reduces, or as the diameter reduces, the speed increases.
Thus, from the question, if diameter A is 20, and B is 10, then definitely, the speed will increase from 348 to a higher rate. Mathematically, we have
20 / 10 = 348 / x, where x is the missing speed.
2 = 348 / x
x = 348 / 2
x = 174 rpm
Therefore, the pulley A must have been running at a speed of 174 rpm

The area of a circle
Answer:
area of the circle = 36π cm²
But area of a circle = πr²
Which means,
πr² = 36π
r² = 36π/π
r² = 36
r = √36 = 6 cm
Radius = 6 cm
Please help I'm in fourth and I do not understand this at all :((
Answer:
Step-by-step explanation:
to under stand this think of a rectangle, or square. that's the yard, then
we know the total area of that rectangle or square, some how. :/ they just tell us, then they tell us the length , or one side of our rectangle or square.
we just have to find the other side.
area of yard (rectangle) = Length * Width
area = L * W
81 = 12 * W
use your algebra skills... ( my calculus prof. tells us that we are all bad at it :))
81/12 = W
6.75 = W
the width of the yard is 6.75 meters

What do you remember about types of angles?
An acute angle is one that measures LESS than 90˚
An obtuse angle is one that measures between 90˚ and 180˚
A reflex angle is an angle that measures between 180˚ and 360˚
There are other many types of angles such as alternate angles and corresponding angles, but those 3 are the main ones.

please click the heart and rate excellent and brainleist to ❤☺️☻♨️♨️☻☺️❤
Answer:
The answer gonna be The letter D
What is the measure of angle D
Answer:
52 degrees
Step-by-step explanation:
A triangle's angles all add up to 180 degrees so we can create this equation:
x + 20 + 3x + 32 = 180
Combine like terms.
x + 3x + 20 + 32 = 180
4x + 52 = 180
Subtract 52 from both sides.
4x = 128
Divide.
128 / 4 = 32
x = 32
Plug in the value of x.
x + 20
32 + 20
52
Angle D is equal to 52 degrees.

What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three. When the proportion is multiplied by 100%, a percentage is found.
The proportion of people who own a bird is:
p = 0.04 + 0.02 = 0.06.
Hence the percentage is of 6%, which means that option C is correct.

Jason is cutting 25 pieces of firewood every 15 minutes. At that rate, approximately how many pieces of firewood will Jason cut in 35 minutes?
Answer:
Approximately 58 pieces can be cut in 35 minutes.
Step-by-step explanation:
Jason is cutting 25 firewood pieces in 15 minutes
Therefore, per minute rate of cutting firewood will be,
Rate = [tex]\frac{\text{Amount of firewood to be cut}}{\text{Time taken}}[/tex]
= [tex]\frac{25}{15}[/tex]
= [tex]\frac{5}{3}[/tex] pieces per minute
By this rate amount of firewood that can be cut = Rate × Time taken
= [tex]\frac{5}{3}\times 35[/tex]
= 58.33
≈ 58 pieces of firewood
Therefore, approximately 58 pieces can be cut in 35 minutes.
