Does 4/2750 reduce into a smaller fraction

The algebraic expression for the area is:

A = (2H - 8)*H/2

Here we want to write the expression:

"the area of a triangle that has a base 8 inches less than 2 times wider than the height."

Remember that for a triangle of base B and height H, the area is:

A = B*H/2

So if the base is 8 inches less than 2 times the height, we can write:

B = 2*H - 8

Replacing that in the area equation we get:

A = (2H - 8)*H/2

That is the equation for the area.

Answer:

∠ A = 23.6°

Step-by-step explanation:

complementary angles sum to 90°

sum the 2 angles and equate to 90

2x - 20 + 3x + 1 = 90

5x - 19 = 90 ( add 19 to both sides )

5x = 109 ( divide both sides by 5 )

x = 21.8

Then

∠ A = 2x - 20 = 2(21.8) - 20 = 43.6 - 20 = 23.6°

The expression which represents the amount he spent at the mall and the estimate of how much Gabe spent if he bought 7 items are:

For the first part of the question, you put the unknown variable multiplied by 16.62.

Next, what you have to do is to then add 26 which equals an unknown variable.

For the second part, since we want to find an estimate of how much Gabe spent if he bought 7 items, we would have to multiply 16.62 by 7 and add 26.

This would be $152.34

The sales tax on telephone is 1 percent.

Calculating the sales tax applied to a purchase is a matter of simply multiplying the tax rate by the purchase price using the equation sales tax = purchase price × sales tax rate. Adding the sales tax to the original purchase price gives the total price paid with tax.

Given that, after sales tax, a $27 telephone costs $27.27.

Here, sales tax =27.27-27

= 0.27

Now, tax rate is 0.27/27 ×100

The mean depression level  for the first group is μ₁ = 16.

The mean depression level for the second group is μ₂ = 12

The weighted mean is closer to 12 than to 16.

The calculated weighted mean  for  CES-D is 13.5

The calculated weighted mean  for  MAST is 17.25 ≈ 17.0 rounded to 17.

Calculating the weighted mean μ

μ=         {where x1 =μ₁ and x2= μ₂ }

μ= 16×6 + 10×12/ 6+10

μ= 216/16

μ= 13.5

The first group has a mean score of μ₁= 18.

The second group has a mean score of μ₂ = 14

Calculating the weighted mean μ

{where x1 =μ₁ and x2= μ₂ ; w1= number of women in the first   group and w2= number of women in the second group}

μ=        

μ= 18×6 + 14×12/ 6+10

μ= 276/16

μ= 17.25≈ 17

The equations x² + 4x + 3 = 0 and x² -6x + 13 = 0 are equivalent to (x + 2)² = 1 and (x - 3)² = -4

An equation is an expression that shows the relationship between two or more numbers and variables. An equation can either be linear, quadratic, cubic and so on

The standard equation of a quadratic function is:

y = ax² + bx + c

1) Given that:

x² + 4x + 3 = 0

subtract 3 from both sides:

x² + 4x = -3

add to both sides the square of half the coefficient of x:

x² + 4x + 4 = -3 + 4

(x + 2)² = 1

2) Given that:

x² - 6x + 13 = 0

subtract 13 from both sides:

x² - 6x = -13

add to both sides the square of half the coefficient of x:

x² - 6x + 9 = -13 + 9

(x - 3)² = -4

Step-by-step explanation:

An equivalent method of approximating values of functions is called an approximation using differentials

The given function is continuous at  x = 5,  RHL = LHL = F(5)

In mathematics, The function is called as continuous at the particular value of x,  if right hand limit, left hand limit and the value of function at x all are equal.

RHL   = LHL  = F(x)

Limit exist and continuous

Given that,

F(x)  =  [x² - 49]/[x² + 6x -7][x² + 14x + 49]

To check whether it is continuous at x = 3

First taking LHL,

[tex]\lim_{h \to \00 } F(x)[/tex]  

[tex]\lim_{h \to \00 }[/tex]   [(5-h)² - 49]/[(5-h)² + 6(5-h) -7][(5-h)² + 14(5-h) + 49]

⇒  -24/(48x144)

⇒   -1/288

Now, taking RHL

[tex]\lim_{h \to \00 }[/tex]   [(5+h)² - 49]/[(5+h)² + 6(5+h) -7][(5+h)² + 14(5+h) + 49]

⇒  -24/(48x144)

⇒   -1/288

The value at x = 3

F(3)  =  [(5)² - 49]/[(5)² + 6(5) -7][(5)² + 14(5) + 49]

⇒  -24/(48x144)

⇒   -1/288

Step-by-step explanation:

Slope int. Form is y=mx+b.

Knowing this, we find the slope either using rise/run or or the slope formula. y2-y1/x2-x1

using rise/run, we rise up 1 unit and run over 2 units to the right.

So mx=1/2x.

Then finding the y-intercept we look at the y-axis and look for where the graph intersects the y-axis. In this case the y intercept is already plotted at (0,-2). So b=-2.

Put all of our information together and receive the equation y=1/2x-2.
