4% of ____ days is 56 days

Answers

Answer 1
Answer: 4%=4/100
4/100=56/x
(4)(14)=56, (100)(14)=1400)
4/100=56/1400
therefore 4% of 1400 days is 56 days
:)
Answer 2
Answer: We know that 4% = 56 days
To work out 1% we can divide the number of days by 4, as 4% / 4 = 1%
56 / 4 = 14
1% = 14 days

What we want to find next is what 100% is
From 1%, we multiply by 100 to get 100%, we do the same to the number of days
14 x 100 = 1400 days

In playing from the tee, a golfer hooks his drive (hits the ball to the left of the correct direction) at an angle of 24 from the intended direction. He estimates that he has driven the ball 215 yards and that it lies 100 yards from the hole. Assuming his estimates are correct, what is the distance from the tee to the hole, to the nearest yard?

Answers

Answer:

245 yards

Step-by-step explanation:

You could say the tee is at (0, 0) and the hole lies on the x-axis.

The path of the ball is the straight-line so, y = tan(24°)x

215cos(24°) = 196.4

215sin(24°) = 87.4

The ball lands at coordinates (196.4, 87.4).

They say the ball lands 100 yards from the hole, the hole is on a circle of radius 100 that is centered at (196.4, 87.4).

Equation of the circle:

(x-196.4)² + (y-87.4)² = 100²

Since the hole is on the x-axis, it lies at the intersection of the circle and the line y = 0 so:

(x - 196.4)² + (0 - 87.4)² = 100²

x = 244.92

The distance between tee and hole is 245 yards.

Answer:

245 yards

This has a lot of scary words and numbers in it, but it's all just fluff.
That big ugly formula is nothing but numbers, except for the 'h' in it
near the end.  When you write your altitude in place of 'h' and push
all the numbers through your calculator, the answer is the air pressure
at that altitude.

All it's asking you to do is this:

-- Write ' 100 ' into the big formula.

-- Run all the numbers through the calculator and get the pressure at 100 meters.

-- Then write ' 1000 ' into the formula.

-- Run the whole thing through the calculator again, and see what
the pressure is at 1,000 meters.

-- Subtract, and see how much the pressure changed between 100 meters
and 1,000 meters.

You want to know what I think the whole idea is here ?  I think the whole idea
is to get you to decide which things to do first as you calculate the formula,
AND to give you practice in using your calculator to do weird stuff.

In the formula, I see a power, a set of parentheses, two multiplications, and
one subtraction. You have to decide what order to do them in.  And THEN,
you have to figure out how to do them all with your calculator.

Here's the order:

-- Inside the parentheses, multiply 2.25577x 10⁻⁵ by 'h' .
-- Inside the parentheses, subtract the result from ' 1 '.
-- Take the number inside the parentheses, and raise it to the 5.25588 power.
-- Then multiply the result by 101,325 .

For 100 meters altitude, the pressure you should get is  100,129 pascals.

Make sure you can get that with your calculator when you put '100' in place
of 'h'.  And then, when THAT works, do it with 1,000 in place of 'h'.

The number you get for  1,000 meters  should be about 10,254 pascals less.

What are the even numbers

Answers

Even numbers are numbers that can be divided, for example, the even numbers are 0, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, and 30
numbers that can be divided by 2 to make a whole number with no remainder
