Answer:

x = 7

Step-by-step explanation:

The final step in this "two-step" linear equation is to multiply both sides by the inverse of the coefficient of x.

__

$\dfrac{4}{3}(x)=\dfrac{28}{3}\qquad\text{given}\\\\\dfrac{3}{4}\cdot\dfrac{4}{3}(x) = \dfrac{3}{4}\cdot \dfrac{28}{3}\qquad\text{multiply by $\dfrac{3}{4}$}\\\\x=\dfrac{28}{4}=7$

The solution is x = 7.

16% of a number is 60. What is that number?<br><br> A375<br> B 432<br> C 456<br> D753

Vlad1618 [11]

Answer:

Its A: 375

Because, if you take 26.6 you have to round it. So, the 6 behind the decimal is over 5 so make the other 6 in front of the decimal a 7. So, the 7 will add 1 to the 2 to make it 3. And i forgot how to get the 5, but trust me dis is right. :3

Given that a = 4.8 × 104 and that b = 8 × 10−3

Paha777 [63]

Answer:

3.84 * 10^0

Step-by-step explanation

Given the following values;

a = 4.8 × 104 and that b = 8 × 10−3

We are to find the product ab

ab = (4.8 × 10^4)(8 × 10^−3)

ab = (4.8*8)(10^4 * 10^-3)

ab = 38.4 * 10^(4-3)

ab = 38.4 * 10^-1

ab = 3.84 * 10 * 10^-1

ab = 3.84* 10^0

<em>Hence the product in standard form is expressed as 3.84 * 10^0</em>

Cargo ships arrive at a loading dock at a rate of 2 per day. The dock has the capability of handling 3 arrivals per day. How man

Vsevolod [243]

Answer:

4 days

Step-by-step explanation:

We need to use the probability functions of each of the intervals to know the Probability number and then use it in the expected value.

P(x>3 cargo ships) = 1-P(x<=3)

P(x>3) = 1-P(x<=3)

P(x>3) = 1-[P(x=0)+P(x=1)+P(x=2)+P(x=3)]

$P(x>3) = 1 - [\frac{e^{-2}2^0}{01}+\frac{e^{-2}2^1}{11}+\frac{e^{-2}2^2}{21}+\frac{e^{-3}2^3}{31}]$

P(x>3) = 1- [0.1353(1+2+2+1.33)]

P(x>3) = 1-0.856

P(x>3) = 0.1431

Als n=30, expected number is

E(x) =30*P(x>3)

E(x) = 30*0.1431

E(x) = 4.293

I expect 4.293 or 4 days per month the block being unable to hanlde all arriving ships

In circle N with m \angle MNP= 48m∠MNP=48 and MN=16MN=16 units find area of sector MNP. Round to the nearest hundredth.

Dafna11 [192]

Answer:

$A=107 square\ unit$

Step-by-step explanation:

From the question we are told that:

$\angle MNP= 48m$

$\angle MN=16 unit$

Generally the equation for Area of a sector A is mathematically given by

$A=\frac{\theta}{360}*\pi*r^2$

$A=\frac{48}{360}*3.14*16^2$

$A=107.18 square\ unit$

$A=107 square\ unit$
