ANSWER PLS ASAP
ANTONII [103]

Lets say for arguments sake that the bag contained  2 blue and 3 red marbles

p:q = 2:3 In order  to get a ratio of 2:1 we would have to add 4  blue  marbles

(6:3 = 2:1).

So the ratio p to r =  2:4  = 1:2  answer.

Line K has a slope of -5. Line j is perpendicular to line k and passes through the point(5,9). Create the equation for line j,
SOVA2 [1]

Since Line J is perpendicular that means that it will be the negative inverse of -5, which is 1/5. So we have to input the point into the slope and do some thinking into what the y-int. will be. 1/5x5= 1. 1+8=9. The equation for Line J is y=1/5x+8

Find the smallest power of 10 that will exceed M. Let M = 118,526.65902.
zavuch27 [327]

Answer:

The smallest power of 10 that will exceed M is 10^{6}.

Step-by-step explanation:

We can use the following approach to determine the smallest power of 10 that will exceed M. We can transform that number into scientific notation, which is of the form:

x.y \times 10^{n}, \forall \,x,y\in \mathbb{N}

Where:

x - Integer part, formed by a digit, which is of the highest order.

y - Decimal part, formed by a digit onwards.

n - Power grade.

The smallest power of 10 that will exceed M is 10^{n+1}

If M = 118,526.65902, then, the power grade is number of spaces that dot must be moved leftwards. In this case, dot must be moved 5 spaces on the left. The integer part is 1 and the decimal part is 1852665902. Then, the value of M in scientific notation is:

M = 1.1852665902\times 10^{5}

Then, the smallest power of 10 that will exceed M is 10^{6}.
