Answer: [tex]\frac{1}{12}[/tex]

Step-by-step explanation:

1. In terms of finding an answer for a question with "of", you have to multiply the two fractions. Do this by multiplying the numerator with each other and the denominator with each other.

2. Now take your two numbers and put them into a fraction, by putting the number you got from the numerator on the top of the fraction and putting the number you got from the denominator on the bottom of the fraction.

3. Your answer is [tex]\frac{1}{12}[/tex].

Answer:

C. x^2 + 2x - 1 = 3

Step-by-step explanation:

The standard form of a quadratic equation is

ax^2 + bx + c = 0

We need to use the quadratic formula and the given expression to find the values of a, b, and c.

The quadratic formula is

[tex] x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a} [/tex]

Where the formula has -b, the problem has -2, so b = 2.

Now we have

ax^2 + 2x + c = 0

In the denominator, where the formula has 2a, the problem has 2(1), so a = 1.

Now we have

x^2 + 2x + c = 0

Inside the root, the quadratic formula has -4ac. the problem shows -4(1)(-4). Since we already know that a = 1, then c = -4.

Now we have

x^2 + 2x - 4 = 0

Let's look at choice A.

x^2 + 1 = 2x - 3

Subtract 2x from both sides. Add 3 to both sides.

x^2 - 2x + 4 = 0   This is not it!

Let's look at choice B.

x^2 - 2x - 1 = 3

Subtract 3 from both sides.

x^2 - 2x - 4 = 0     This is not it!

Let's look at choice C.

x^2 + 2x - 1 = 3

Subtract 3 from both sides.

x^2 + 2x - 4 = 0     This is it!

Answer: C. x^2 + 2x - 1 = 3

[tex]x^{2} +2x -1=3[/tex] equation could be solved using this application of quadratic formula.

Option D is correct.

A quadratic equation is an algebraic equation of the second degree in x. The quadratic equation in its standard form is  [tex]ax^{2} +bx +c =0[/tex], where a and b are the coefficients, x is the variable, and c is the constant term.

The quadratic formula is used to find the roots of a quadratic equation.

[tex]x=\frac{-b \pm \sqrt{b^{2} -4ac} }{2a}[/tex]

According to the question

[tex]x=\frac{-2 \pm \sqrt{2^{2} -4(1)(-4)} }{2.1}[/tex]

We all know the quadratic formula for finding the factors of a quadratic equation

[tex]x=\frac{-b \pm \sqrt{b^{2} -4ac} }{2a}[/tex]

By comparing two formulas we get a = 1, b = 2, c = -4

Standard form of quadratic equation is [tex]ax^{2} +bx +c =0[/tex]

Substitute a = 1, b = 2, c = -4 in the standard form of quadratic equation

⇒ [tex]x^{2} +2x-4=0[/tex]

We can write it as

⇒ [tex]x^{2} +2x -1=3[/tex]

[tex]x^{2} +2x -1=3[/tex] equation could be solved using this application of quadratic formula.

Option D is correct.

Step-by-step explanation:

let 1st week magazines sold be x

number of magazines sold in 2nd week is 6 more than 1st week that is (x+6)

number of magazines sold in 3rd week is double of 1st week that is 2x

total=94

x+(x+6)+2x=94

x+x+6+2x=94

4x=94-6

4x=88

x=88/4

x=22

Answer:

Step-by-step explanation:

Ratio = 4 :3

Other two sides = 4x , 3x

Pythagorean theorem

(4x)²  + (3x)² = 20²

16x² + 9x²  = 400

          25x² = 400

             x² = 400 ÷ 25

            x²  = 16

             x = √16

x = 4 cm

4x = 4*4 = 16

3x = 3*4 = 12

Sides = 16cm  , 12 cm

Answer:

Step-by-step explanation:

outer area=

first need to find the circumference of outer diameter

= π×4.8

= 15.079644.... cm

to find the outer curved area you would then do

= 77×15.079644

(ii) =1161.13264 cm²

inner curve area

circumference= π×4

=12.5663706.... cm

77×12.5663706

(i) =967.610537 cm²

total surface area=

as the outer and inner curved areas are already found only the top and bottom surfaces need to be

= area of larger circle

=π×4.8²

=72.382294.... cm²

smaller circle

=π×4²

=50.2654824.... cm²

72.382...-50.265

=22.1168116 x 2

=44.2336232 cm²

total surface area

(iii)= 2172.9768 cm²

Step-by-step explanation:

Answer:

these numbers are greater than not less than

take x =initial deposit amount. then make equation:

x+75.5+55.25-25.15-18.65 = 210.85

simplify:

x+86.95 = 210.85

x=210.85 - 86.95

x=123.90

so Initial deposit amount is $123.90

check:  210.85+18.65+25.15-55.25-75.5 = 123.9

123.9 = 123.9

7 3/8

Step-by-step explanation:

You have to make 17 1/2 and 10 1/8 into improper fractions, which would be 35/2 and 81/8. Then you have to find a common denominator, which is 16, so you get 280/16 - 162/16. You subtract and get 118/6, which simplifies to 7 3/8. Hope this helps :)
