Enter the value of w so the expression -5 +0.6W is equivalent to w (2.5 – 0.3w)​

Answers

Answer 1

9514 1404 393

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.

Enter The Value Of W So The Expression -5 +0.6W Is Equivalent To W (2.5 0.3w)

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

Answers

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.

Answer:

P=16 cm.

Step-by-step explanation: it is 16 inches

Answer:

1,563.5 in³904.8 yd³2,144.7 mm³1,288.2 cm³434.9 in³

Step-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.

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)

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.

Answers

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.
