Which is bigger 6.6 or 0.78 ?
6.6 is bigger
===================
x^2 - x......when x = 2
2^2 - 2 =
4 - 2 =
2 <==
====================
A = bh
60 = 10h
60/10 = h
6 = h....so height is 6 m
====================
900 decreased by 5% =
900 - 0.05(900) = 900 - 45 = 855 <==
=====================
2(x + 3) = 8
2x + 6 = 8
2x = 8 - 6
2x = 2
x = 2/2
x = 1 <==
=======================
360 in a ratio of 1 to 4.....

1:4......added = 5

1/5(360) = 360/5 = 72
4/5(360) = 1440/5 = 288

ratio is 72:288
=======================
3,8,13,16,23.....this is an arithmetic sequence with a common difference of 5

the nth term : an = a1 + (n - 1)d
an = 3 + 5(n-1) <===
======================
are there decimals in this problem......because the angles of a quadrilateral , when added = 360 degrees
======================
75% = 66....what is full cost...
75% of what is 66..
0.75x = 66
x = 66 / 0.75
x = 88 <==
=====================
y = 4x - 1...when x = -2
y = 4(-2) - 1
y = -8 - 1
y = -9 <==
======================
6.5 ???? cant see the problem
======================
circumference of circle with radius of 4.....
C = 2(pi)r
C = 2(3.14)(4)
C = 25.12 cm <== or C = 8*(pi)
=====================
6 km / h for 2 hrs 20 min...

6 / 60 = 0.1 km per minute......0.1(140) = 14 km <==
=====================
to increase an amount by 4.6%, ur multiplier would be 1.046
=====================
(x - 5)(x + 4) =
x^2 + 4x - 5x - 20 =
x^2 - x - 20 <===
======================
500 increased by 4.6%....
500(1.046) = 523 <==
=======================
2x > 7
x > 7/2 or x > 3.5
======================
500 tickets are sold.....probability of winning first prize (if there is only 1 first prize) is 1/500....dont know how many tickets he bought
======================
6 * 0.6 = 3.6......u simply multiply 6 * 6 = 36....and since 0.6 has a decimal 1 space to the left, in ur answer(36)...move the decimal 1 space to the left giving u 3.6
=======================
5x - 2y....when x = -2, y = -3
5(-2) - 2(-3) =
-10 + 6 =
-4 <==
=======================
0.521 to one significant figure = 0.5
=======================
4,7,13,22,34......
4 to 7 = 3 spaces
7 to 13 = 5 spaces
13 to 22 = 9 spaces
22 to 34 = 12 spaces
I am sorry....I do not know this one..cannot find the pattern
=======================
V= bh
V = 3*10
V = 30
not sure about this...because volume of a prism is base * height....there is o (pi) in the formula.
=====================
7.34 * 4.71 = 34.5714 rounds to 34.57
5.63 + 11.89 = 17.52
====================
y = x^2 + 2x......x = -2
y = -2^2 + 2(-2)
y = 4 - 4
y = 0 <==

How to solve<br> ?? I need help guys please anyone just help
statuscvo [17]
Bill's original ratio is like this...
6 to 10

You need to solve for this...
x to 15

You have to multiply both sides of the original ratio by 15...
6 times 15 = 90
10 times 15 = 150

Your new ratio is 90 to 150
Which reduces to 3 to 5

Yout new ratio is 3 to 5

Picture above ^^^^^^^
Nitella [24]

Answer:

Step-by-step explanation:

Since this is a test/hw, I'll give a hint.

This problem at first can seem a bit difficult with q's and power's everywhere.

But let's take a step backward. A power is when your mutiplying something by itself again and again.

Ex: 3^3=3 times 3 times 3

But what if we had something liiiike this:

(3^3)2

In this case its now

(3 times 3 times 3)^2, so its "techinicaly" (27)^2. And you would a fairly large number, which I'm to lazy to solve. But that's not the point.

We've seen what a power is deconstructed, and what a power is. Because my explantion probably confused you more than it helped, I'll give an example.

(2^2)^2=(2 times 2)^2=(4^2=16=2^4

However, there is a shorter way to solve it.

(2^2)^2=2^(2 times 2)=2^4

Hope this helps.

Kazeer [188]

Answer:

5 months

Step-by-step explanation:

Equation A: 15+30x

Equation B: 35x

In 5 months Gym a will cost 15+30(5) or $175 and Gym B will also cost $175.
Basically all you have to do is apply reasonable numbers until you find out where the costs will meet up.

Could I get some help?
balandron [24]

Answer:

#adult tickets sold = 346

#student tickets sold = 812

Step-by-step explanation:

let 'x' = # adult tickets sold

let 'y' = # students tickets sold

System of Equations:

x + y = 1158

5x + y = 2542

I used the elimination method and multiplied the first equation by -1

  -x - y = -1158

+<u> 5x + y = 2542</u>

  4x  =  1384

   x = 346

346 + y = 1158

y = 812
