what times the same number will give you the answer

example;
lets say you want to find the square root of 4 2(2)=4 it has to be same number multiplying by its selkf to get answer

Since he makes the same number of packs we combine the weight of the packs into one for now and divide the total weight by the pack weight.
345/2.5 = 138
Now we just times the answer by two to separate the sizes of packs again.
138*2 = 276

cody:
What is 5.98 x 10^24
So.
First lets figure out what 10 to the 24th power is.
10^24 is = 10*10*10*10*10*10*10*10*10*10*10*10*10*10*10*10*10*10*10*10*10*10*10*10
10^24 is = 1,000,000,000,000,000,000,000,000
--------------------------
Now we have 5.98 * 1,000,000,000,000,000,000,000,000
5.98 * 1,000,000,000,000,000,000,000,000 = 5,980,000,000,000,000,000,000,000

Would you say 5980^24

On most calculators, arctan is represented as tan ^-1. You will probably have to press [shift] or [2nd] and then [tan]. You should see tan ^-1 written above [tan].

Let Angle 1 = m, and let Angle 2 = n.

n measures 6 degrees less than twice m, so:
n=2m-6

Supplementary Angles add up to 180 deg, so:
m+n=180
m+2m-6=180
3m-6=180
3m=186
m=62 degrees

Therefore:
n=2m-6
n=2(62)-6
n=124-6
n=118 degrees

The two angles are 62 degrees, and 118 degrees.

make 8/6 into a decimal
8/6 IS ACTUALLY 8 DIVIDED BY 6
YOU CAN REDUCE IT FIRST TO 4/3 (FOUR DIVIDED BY THREE)

[4/3] IS 1.33333333333333333333333333333

SO, THE 8/6 IS ALSO 1.33333333333333333333333

high fountain of water is located at the center of a circular pool as in the figure. A student walks around the pool and estimates its circumference to be 212 m. Next, the student stands at the edge of the pool and uses a protractor to gauge the angle of elevation of the top of the fountain to be 53.7◦.
How high is the fountain? Answer in units of m

Think if you were standing on top of the fountain. The distance from the fountain to the edge would be the radius of a circle or the base of a triangle. The triangle would consist of the base, which is the radius of the pool, the height of the fountain would be the opposite side of the triangle.

The base of the triangle, or the adjacent side, would equal the radius of the fountain.
Since we have the circumference, C = 212m, we need to find the radius which equals 1/2 of the diameter.
Thus the diameter is = C/pi = 212/3.14 = 67.48 meters.
The radius R = 1/2 D = .5 X 67.48 = 33.9m
Since we have the base of the triangle and the angle, we can find the height
The height of the triangle =

tan 53.7 multiplied by the adjacent side=1.361335036296 multiplied by33.9 = 46.14m

5w - 8/3 = 4w + 2
5w - 8/3 - 4w = 4w + 2 subtract 4w from both sides
w - 8/3 = 2
w - 8/3 + 8/3 = 2 + 8/3 add 8/3 to both sides
w = 14/3

Lay out the parenthesis like this:

(5x-3)(5x-3)

Now foil it:

25x^2-15x-15x+9

Which simplifies to:
25x^2-30x+9

Now subtract 2x+1

25x^2-32x+8

Then use the quadratic formula to solve

Decimal places go in order from left to right-

1 decimal place: 0.3 (round up if the number in the tenths place is 5 or higher)

2 decimal places: 0.29 (again, round up if the number in the hundredths place is 5 or higher)

You have to follow order of operations:
multiplication comes before addition

4*2=8
27*-7= -189
8+(-189)= -181

-181 is your answer

Any number minus a negative number effectively just means add, so you can read this problem as: -5+5+5.

Google says that 1 mile = 5280 feet.
So if the gocart would go at 5280 feet per hour, it would go at 1 mile per hour.
And if the gocart would go at (2*5280) feet per hour, it would go at 2 mile per hour.
607200 / 5280 = 115, so the top speed is 115 mph.
----------------------
It helps a lot if you keep the dimensions during calculation when solving physics exercises.
Just use them as joker numbers or variables as whole and keep them everytime. Don't forget them.

1 mile = 5280 feet. just like 1 * mile = 5280 * feet
Divide by 5280
1/5280 mile = 1 feet, so feet = 1/5280 mile

Top speed is 607200 feet / hour
Substitute feet with the thing above we just found out.
Top speed = 607200 feet / hour = 607200 ( 1/5280 mile) / hour = 607200/5280 mile/hour = 115 mile/hour = 115 mph.

If you use the dimensions correctly, they help checking yourself.

Good luck!
