Answer:
5/12
Step-by-step explanation:
total number of marble is 12 total number of blu is 5
Answer:
12.5%
Step-by-step explanation:
you have 7 reds of 14 total.
the 1st marble has 7 of 14 probability of being red
the 2nd has 6 of 13 of being red
the 3rd has 5 of 12 of being red
multiplying this out you have:
(7/14)*(6/13)*(5/12)=210/2184
THAT will condense down to 5/52 or 9.615%
this does assume not placing the balls back in between draws
if you do put them back in between draws you would have 7 of 14 chance each draw
that would give you by multiplying out
(7/14)*(7/14)*(7/14)=343/2744
that condenses to 1 of 8 or 12.5%

Answer:
1/ 8 ^2
Step-by-step explanation:
When we are dividing exponents with same base all we do is subtract the denominator by the numerator (the exponent)
In this scenario we have 8^3 / 8^5
We are saying 8 * 8 * 8 / 8 * 8 * 8 * 8 * 8 When we cancel out the 8's were left with 1 / 8^2
or we could just subtract if that method is too long

what is 2 3/4 as an improper factor..? just asking
Answer:
11/4
Hope this helps
Answer:
11/4
Step-by-step explanation:
An improper factor is a fraction that has a higher numerator (number in top) than the denominator (number in the bottom). Some examples of improper factors are 9/8 or 5/3 bc the top number is higher than the bottom one.
You can get the answer by multiplying 2 × 4 bc we want to know how many fourths (1/4) are in 2. In this case there are 8
then we add 8/4 with 3/4 to get 11/4

4) Haleakela is a 10,000 foot high dormant volcano on Maui, Hawaii. The peak is a horizontal distance of 30,000 feet from the ocean. At what angle would you have to look up to see the peak if you were standing at the edge of the ocean?
ITS 67 dgrees Step-by-step explanation: NP BRAINLIEST OR NA :)?
The angle that you would have to look up to see the peak if you were standing at the edge of the ocean is 18.4°.
Angle:Let x represent the angle
Tan x=Height/Horizontal distance
Tan x =10,000/30,000
x=Tan^-1 (1/3)
x=18.4°
Inconclusion the angle that you would have to look up to see the peak if you were standing at the edge of the ocean is 18.4°.

Answer:
Aonnalin, great name :) answer as below
Step-by-step explanation:
They tell us to use slope-intercept form. This is something you will just have to remember y = mx+b
It is confusing b/c there is the other one, the point-slope formula too. but just remember both and know that the point-slope one is to get to the slope-intercept one. y-y1 = m(x-x1)
m= slope
m = (y2-y1) / (x2-x1)
P1= (0,7) in the form (x1,y1)
P2 =(8,-2) in the form (x2,y2)
m = -2-7 / 8-0
m = -9 / 8
now that we have the slope, just use either point with the point-slope
y-7 = (-9/8)(x-0)
y-7 = -9x/8
y = -9x/8 + 7
y = [tex]\frac{-9}{8}[/tex] X + 7
slope-intercept form :)

160 - 55 = 105
105 ÷ 35 = 3
Answer:
3 hours
Step-by-step explanation:
First, we must turn this into an equation:
35n + 55 = 160
N = number of hours
Next, solve:
35n + 55 - 55 = 160 - 55
35n = 105
n = 3

Answer:
216 cm²

A quantity with an initial value of 650 grows exponentially at a rate of 20% every week. What is the value of the quantity after 70 days, to the nearest hundredth?
Answer:
4024.62
Step-by-step explanation:
the value in 70 days can be determined using his formula
FV = P (1 + r)^n
FV = Future value
P = Present value = 650
R = growth rate = 20%
N = number of weeks = 70 / 7 = 10 weeks
650 x (1.2)^10 = 4024.62
Answer:
The Answer is 4024.62
Determine the numerical value of x
Answer:
x = 10
Step-by-step explanation:
OA = OD ( both radii of the circle )
OD = OB + BD = x + 16
OB is at right angles to OB ( line from centre to midpoint of chord is right )
Using Pythagoras' identity in right triangle ABO
OA² = OB² + AB² , that is
(x + 16)² = x² + 24²
x² + 32x + 256 = x² + 576 ( subtract x² from both sides )
32x + 256 = 576 ( subtract 256 from both sides )
32x = 320 ( divide both sides by 32 )
x = 10
