What is the width of a rectangle with a length of 12cm and area of 192cm2

Mathematics

Area = Length x Width 

Given that length = 192cm² and the length = 12 cm, we plug these values into the equation and solve for the width:

192 = 12 x width

192 = 12width
 
width = 192 ÷ 12

width = 16 cm

Answer: Width = 16 cm

Hello!

\rm Answer:

The width of the rectangle is \boxed{16} cm^2.

_____________________________

\rm Explanation:

Formula for area is:

A = l × w

We know that we must multiply the length by the width to find the area.

Since we want to find one of the rectangle's dimensions, and not the area, we'll use the opposite operation.

What's the opposite of multiplication? Division!

-------------------------------------------------------

Divide the area of the rectangle by its length to find the width:

W = A ÷ l

W = 192 ÷ 12

W = 16

If the product of a number and -4 is subtracted from the number, the result is 3 more than the number. Find the number
lesya [120]

Answer: The number is 0.75 or 3/4

Step-by-step explanation:

let x = the number.

Now set up an equation: The product of a number (x) and -4 = -4x. So -4x is subtracted from the number - x.     x-(-4x)

Then, that equals 3 more than the number (x) = x+3

So the equation is x-(-4x)=x+3.

Then, solve the equation!

x-(-4x)=x+3

x+4x=x+3  (Distribute the negative to the parentheses)

5x=x+3  (Combine like terms)

4x=3  (Get the Xs on one side by subtracting x from both sides)

x=0.75 or 3/4  (divide by the coefficiant, 4, on both sides)

Simplifly the expression 64^7/12
Evgesh-ka [11]

Answer:

8\sqrt{2}

Step-by-step explanation:

we have

64^{\frac{7}{12}}

we know that

64=2^{6}

substitute

64^{\frac{7}{12}}=(2^{6})^{\frac{7}{12}}\\ \\=(2)^{\frac{6*7}{12}} \\ \\=(2)^{\frac{7}{2}} \\ \\=\sqrt{2^{7}}\\ \\=2^{3}\sqrt{2} \\ \\=8\sqrt{2}

Answer:

E. When the sample size​ increases, because the standard deviation of the distribution of sample means better estimates the population standard deviation for larger sample sizes.

Step-by-step explanation:

  • T distribution is similar to the normal distribution and is seen when the estimates of the variance are based on the degree of freedom and has a relatively more score in its tail and has a greater change of extreme values.
