<h3><u>3</u><u>6</u> is the answer.</h3>

Step-by-step explanation:

Put value of b as given and using BODMAS rule,

$6(2b - 4)$

$= > 6((2 \times 5)-4)$

$= > 6(10 - 4)$

$= > 6 \times 6$

$= > 36$

Henve, value of of the given expression is $36$

ch4aika [34]

Answer:

0.093 ft/min

Step-by-step explanation:

V = 4/3 π r³

Take derivative with respect to time:

dV/dt = 4π r² dr/dt

Plug in values:

141 = 4π (11)² dr/dt

dr/dt = 141 / (484π)

dr/dt ≈ 0.093

The radius is increasing at 0.093 ft/min.

2/7x = 10 show work plz

Rashid [163]

Answer:

x = 35

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

2/7*x-(10)=0

Simplify —

(— • x) - 10 = 0

Subtracting a whole from a fraction

Rewrite the whole as a fraction using 7 as the denominator :

10 10 • 7

10 = —— = ——————

1 7

Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

2x - (10 • 7) 2x - 70

————————————— = ———————

7 7

Pull out like factors :

2x - 70 = 2 • (x - 35)

2 • (x - 35)

———————————— = 0

When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

2•(x-35)

———————— • 7 = 0 • 7

Now, on the left hand side, the 7 cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

2 • (x-35) = 0

Solve : 2 = 0

This equation has no solution.

A a non-zero constant never equals zero.

Solve : x-35 = 0

Add 35 to both sides of the equation :

x = 35

For the month of March in a certain city, 57% of the days are cloudy. Also in the month of March in the same city, 55% of the da

oksian1 [2.3K]

Answer: 0.9649

Step-by-step explanation:

Let A denote the event that the days are cloudy and B denotes the event that the days are rainy.

Given : For the month of March in a certain city, the probability that days are cloudy : $P(A)=0.57$

Also in the month of March in the same city,, the probability that the days are cloudy and rainy : $P(A\cap B)=0.55$

Now by using the conditional probability, the probability that a randomly selected day in March will be rainy if it is cloudy will be :-

$P(B|A)=\dfrac{P(A\cap B)}{P(A)}$

$\Rightarrow\ P(B|A)=\dfrac{0.55}{0.57}\\\\=0.964912280702\approx0.9649\ \ \text{[Rounded to four decimal places.]}$

Hence, the probability that a randomly selected day in March will be rainy if it is cloudy = 0.9649
