1.5/4x+1=0.4/x+4 PLEASE HELP ITS PROPORTIONS
Serhud [2]

Answer:

Proportion states that the two fractions or ratios are equal

Given the equation:  \frac{1.5}{4x+1} = \frac{0.4}{x+4}

By cross multiply we get;

1.5(x+4) = 0.4(4x+1)

Using distributive property; a\cdot (b+c) = a\cdot b+ a\cdot c

1.5x + 6= 1.6x + 0.4

Subtract 0.4 from both sides we get;

1.5x +5.6= 1.6x

Subtract 1.5x from both sides we get;

5.6= 0.1x

Divide both sides by 0.1 we get;

x = \frac{5.6}{0.1}

Simplify:

x = 56

Therefore, the value of x that satisfy the equation \frac{1.5}{4x+1} = \frac{0.4}{x+4} is, 56

PLEASE HELP<br><br> Find the surface area of the triangular prism.
ASHA 777 [7]

Answer:

139

Step-by-step explanation:

First, find all the faces that you must find the areas of. In this case, you need to find the areas of two triangles and three rectangles.

In this triangular prism, the base is one triangle. If the area of the base is 7.75, we can assume that that holds true for both bases, and multiply 7.75 by 2 in order to find the area of both triangles.

Now find the area of each of the three rectangles by multiplying their individual heights and bases by each other. You should get 38, 47.5, and 38 as the areas of the rectangles.

Now add all the individual area's together. (They're bolded for clarity).

As the number of degrees of freedom for a t distribution increases. True or False
valkas [14]

Answer:

t distribution behaves like standard normal distribution as the number of freedom increases.

Step-by-step explanation:

The question is missing. I will give a general information on t distribution.

t-distribution is used instead of  normal distribution when the <em>sample size is small (usually smaller than 30) </em>or <em>population standard deviation is unknown</em>.

Degrees of freedom is the number of values in a sample that are free to vary. As the number of degrees of freedom for a t-distribution increases, the distribution looks more like normal distribution and follows the same characteristics.

IDK how to do this who else does
Nezavi [6.7K]

Answer:

36 ft²

Step-by-step explanation:

Scale factor means the side length are multiplied by some value.  Here, Jack takes 4 feet and multiplies it by a value of 1 1/2.  

The side length he wants is one and a half times the length of his neighbor's.  

The 'one' means the side length you started with, and the 'one half' means add half to the original length.

one and a half of four is six.  (4 plus half of 4, which is 2, so 4 plus 2)

The box is square, so each side is 6 ft, so the area of the box is 6x6 = 36 ft²
