Answer:
15
Step-by-step explanation:
Red : Blue :
3 8
We have 40 blue marbles
Multiply 8 by what to get 40
40/8 =5
So we need to multiply by 5
Red : Blue :
3*5 8*5
15 40
There are 15 red marbles

Answer:
the graph corresponds to function "D" 
Step-by-step explanation:
Since the graph shown corresponds to an exponential "decay" (the function decreases as we move from left to right), the base of the exponent has to be a number smaller than 1 (one). So we examine the only two options that give such (options C and D which have fractions as the base - 1/3 and 1/5 respectively)
From there, we analyze which of the two functions satisfies the crossing of the y-axis at (0,3) which is clearly shown in the graph:
We study both:
function C at x = 0 gives:

while function D at x = 0 gives:

Therefore, the graph corresponds to function "D"
-6x-x^2-8 = -(x+2) x (x+4)
(This is if you are factoring the expression)
<u>Answer:</u>
The geometric mean between each pair of numbers 
<u>Solution:</u>
The Geometric mean between two numbers a and b is given as Geometric mean =
--- eqn 1
The Geometric Mean is a special type of average where we multiply the numbers together and then take a square root for the numbers.
From question, given that two numbers are 
Hence we can say “a” =
=7
Similarly “b” =
= 29
We have to find the geometric mean between “7” and “29”
By using equation 1,
Geometric mean between 7 and 29 =
= 14.24
Hence the geometric mean between
