Anything times 1 is the number you multiplied, so 10

example: 9*1=9

8*1=8

40.80/4 and 81.60/8   are equal ratios

So

40.80 / 4   =  $10.20 per hour

Compare

2.79/2   and  2.98/3

Whichever is less is the better deal......

(8+ 1/2 )  - (3 + 3/4) =

(17/2) - (15/4)   =   get a common denominator = 4

(34/4) - (15/4)  =

19/4 km =  4 + 3/4  km

7(1 + .045)^5 = $8.72

The sequence progression is

30(-1/3)^n-1    for n = 1, 2, 3, 4......

So the next one would be

30(-1/3)^5-1  = 30(-1/3)⁴   = 30(1/81) = 30/81 = 10/27

And I'll let you do the next two....

 7x < 84 divide both sides by 7

x < 12

And that's it....

To find the hypotenuse, square each leg and add together

So

150^2 + 120^2 = 36900

The hypotenuse will be the square root of this

√36900 = about 192.1

Looks like you were pretty close....!!!

figure it out lazyy

So we have

log₁₅ (1/√15)  =

log₁₅ 15^-1/2 =

(-1/2)log₁₅ 15 =

-1/2

Using dimensional analysis to convert km to miles, we have

100km x  1000m/ 1 km x 39.37in / 1m x 1ft / 12 in x 1 mile / 5280 ft = 62.136m/hr

Infinity, because 0*200,000,000 is still 0.

The sq. root of 144 is 12.

 No, think about it 1 divided into 0 parts would be zero.

No Solution. There is no number that can devide by 0

Note the cycle

9^1 = 9

9^2 = 81

9^3 = 729

9^4 =  6561     and this pattern repeats for every "block" of 4 powers

Note that 40 is evenly divisible by 4, so 9^40 has a "ones" digit that completes this cycle. So....9^40  ends in a "1"

Here is the statement that you're looking for

abs (x - 52) ≤ 3 

Where x is the temperature ......if "within" does not include those temperatures that are exactly 3 degrees on either side of 52, we only need the " < " sign

this person may be right beyond my knowledge, but actually, it is for the the inputs and outputs for a function. for example, if a table was like this:

then the braces for the input would be {1,2,3,4,5}.

also, in a function, for example f(x)=x+1 it would be for {all real numbers}

Since <C is 90 degrees, the opposite side to this is the diameter = 16.48. We can find the opposite side b by using the Law of Sines.

b/sin 63 = 16.48/sin90

b = 16.48 sin 63 = about 14.68

"a" can be forund by using the Pythagorean Theorem or the Law of Sines.....so using the Law of Sines, we have that angle A = 90- 63 = 27

a = 16.48sin 27 = about 7.48

There are many answers to this one. If you like to watch Vine, then I guess 21. If you are just a regular person, then it is 19. If you are stupid, it something else.

Just multiply 73 by 15 and divide this by 400....this will give you your answer.....

$${\mathtt{\pi}}{\mathtt{\,\times\,}}{{\mathtt{r}}}^{{\mathtt{2}}} = {\mathtt{3.141\: \!592\: \!653\: \!589\: \!793\: \!2}}{\mathtt{\,\times\,}}{{\left(\underset{{\tiny{\text{Error: Unknown Identifier}}}}{{\mathtt{r}}}\right)}}^{{\mathtt{2}}}$$

Multiply 16990 by 0.23 on your calculator.

The half-hearted answer is $$${\frac{{\mathtt{75}}}{{\mathtt{8}}}}$$. However, when was the last time you bought something and paid $$${\frac{{\mathtt{75}}}{{\mathtt{8}}}}$$ for it? Since price is never in fractions, first convert to a mixed number. You get $9 $${\frac{{\mathtt{3}}}{{\mathtt{8}}}}$$. Now convert to a decimal, which is $9.375. Since you can't pay half a cent for something, this would generally be rounded to $9.37.
