Answer:
w = -2 or 8 1/3
Step-by-step explanation:
Setting the two expressions equal makes a quadratic equation:
-5 +0.6w = w(2.5 -0.3w)
0.3w^2 -1.9w -5 = 0 . . . . . . subtract the right-side expression
3w^2 -19s -50 = 0 . . . . . . . multiply by 10 to give integer coefficients
(3w -25)(w +2) = 0 . . . . . . . factor
We can use the zero product rule to find the solutions. The product will be zero only if a factor is zero.
3w -25 = 0 ⇒ w = 25/3 = 8 1/3
w +2 = 0 ⇒ w = -2
The values of w that make the two expressions equivalent are -2 and 8 1/3.

Question
A bag contains 3 pink gumballs, 4 red gumballs, and 2 green gumballs. Find the probability that you do not draw all green
gumballs if there are 3 drawings that occur and the gumballs are replaced after each draw. Round your answer to two
decimal places.
Provide your answer below
Answer:
.47
Step-by-step explanation:
9 gumballs in all
7 of them are not green
'ng' = not green
P(ng,ng,ng) = 7/9 x 7/9 x 7/9 = .47
The probability will be 0.87.
What is mean by Probability?
The term probability refers to the likelihood of an event occurring.
Given that,
Number of Pink gumballs = 3,
Number of Red gumballs = 4,
Number of Green gumballs = 2,
Now,
Total number of gumballs = 3 + 4 + 2 = 9,
Thus, total number of ways of selecting 3 gumball
= 9 x 9 x 9
= 729
Number of Green gumballs = 2
Number of gumballs other than green = 9 - 2 = 7
So, Number of ways to draw 3 gumballs other than green is;
= 7 x 7 x 7
= 243
And, Number of ways to draw one green and two other gumballs in 3 draw = 2 x 7 x 7 + 7 x 2 x 7 + 7 x 7 x 2
= 294
( Since the green gumballs can be drawn in 1st, 2nd, and 3rd draw.)
Thus, The probability of not drawing all 2 green gumballs is;
= 343 + 294 /729
= 637/729
= 0.87
So, The probability will be 0.87.

the measurement is 4 and 6 what is the perimeter.
Answer:
P=16 cm.
Step-by-step explanation: it is 16 inches
Answer:
To find the perimeter, you do 2 x length + 2 x width
So it would be, 2x4 + 2x6 = 20 inches
You didn't measure properly!!!
Personally, I think you meant to write 3 and 5, that would make 16

Answer:
1,563.5 in³904.8 yd³2,144.7 mm³1,288.2 cm³434.9 in³Step-by-step explanation:
The formula for the volume of a sphere is ...
V = (4/3)πr³
When you have several of these calculations to do, it is convenient to let a graphing calculator or spreadsheet do them. A spreadsheet can do the rounding for you, too. The results are attached. The units are the cube of the units of the radius.
Example calculation:
(4) Radius = diameter/2 = 13.5 cm/2 = 6.75 cm
V = (4/3)π(6.75 cm)³ = 4.18879 × 307.547 cm³ = 1288.2 cm³
Note that the constant (4/3)π ≈ 4.18879 remains the same for each calculation. All you need to do is multiply that by the cube of the radius.
I suck at geometry can someone help??
Answer:
Last option is the correct answer
Step-by-step explanation:
None of these choices are correct.
Correct order would be,
Since,
58° < 59° < 63°
Therefore,
AC < CB < AB
AC, CB, AB (this is the correct order of the sides from shortest to longest.)

23. Find the perimeter and area of the rectangle below. 10x^2 7xy^2
Answer:
Area= 70x^3y^2
Perimeter = 20x^2 + 14 xy^2
Step-by-step explanation:
Area is just multiplying the length and width, I multiplied the constants first which gets us 70 then multiplied the variables, they combine however only the x's can be multiplied to each other which results in 70x^3y^2 . The perimeter you just multiply the length by two and the width by two, they are separate because the variables when added to each other do not combine.

Joe has $70 in a savings account. The interest rate is 10% per year and is not compounded,
How much interest will he earn in 4 years?
Use the formula i = prt, where / is the interest earned, p is the principal (starting amount),
is the interest rate expressed as a decimal, and t is the time in years.
Answer:
$28
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 10%/100 = 0.1 per year,
then, solving our equation
I = 70 × 0.1 × 4 = 28
I = $ 28.00
The simple interest accumulated
on a principal of $ 70.00
at a rate of 10% per year
for 4 years is $ 28.00.

3. Factor the following trinomial. x^2 - 15x + 56.
Step 1: The trinomial factors as x2 + bx+ c = (x + p)(x + 9), where p+ q = b and p. q = c. Fill in the
following table with all of the possible values of p and q, using the fact that their product is the
constant term, c = 56. (4 points)
Answer:
(-7, -8)
Step-by-step explanation:
Yes, this is the same answer as the other person, but I just included the other factors, a picture of my table, and the answer to part two is "The pair (-7, -8) equal the coefficient of the x-term in the trinomial."
