Answer:

3/16 / 5/6 = 9/40

7 / 1/6 = 42

2 1/6 / 1 1/3 = 1  13/20

2 1/7 / 3/28   = 20

Here we want to order from least to greatest the following expressions:

7.12 = 7.121212...

√75

√45

We will find that the order is: √45 < 7.12 < √75

remember that:

√x = y

such that:

y*y = x

From this, is easy to see that:

√45 < √75

Now to see where 7.1212... enters, we need to compute:

(7.1212...)*(7.1212...) = (7 + 0.1212...)*(7 + 0.1212...)

                               = 7*7 + 2*7*0.121212... + 0.1212...*0.1212...

                               = 49 + 2*7*0.121212... + 0.1212...*0.1212... > 45

So we know for sure that:

7.12 > √45

And 8*8 = 64 < 75

then:

7.12 < 8 = √64 < √75

For transitivity, we have:

7.12< √75

Then the order, from least to greatest, is:

√45 < 7.12 < √75

Work Shown:

1.66 = 1.66/1.00

1.66 = 166/100

1.66 = 83/50

In the second step, I moved the decimal point over to the right two spaces for each value. So 1.66 turns into 166 and 1.00 turns into 100. This is the same as multiplying top and bottom by 100.

In the third step, I divided both parts by the GCF 2. So 166/2 = 83 and 100/5 = 50.

You should have 83/50 in your answer choices, but it's not listed. So the next best thing is 166/100.

Answer:

40 m/s/s.

Step-by-step explanation:

Acceleration = velocity / time

= 200 / 5

= 40 m/s/s.

Answer:

a = 40m\s^2

Step-by-step explanation:

acceleration is the change of velocity in a certain time interval, which means that it is equal to ( V final - V initial ) \ t

so acceleration here is ( 200 - 0 ) \ 5

which is equal to: 40 m\s^2 and that means that the racer is speeding up by 40 meters each second

You're very close. The answers you've selected are correct, but there's one third series that's also alternating. Choice C is also an answer due to the [tex](-1)^n[/tex] term.

Any alternating series is in the form [tex]\displaystyle \sum (-1)^n*a_n[/tex] or [tex]\displaystyle \sum (-1)^{n+1}*a_n[/tex] where [tex]a_n[/tex] is any sequence.

Choice E comes close, but the 2n being the exponent means that we don't have alternating signs (positive, negative, positive negative, etc). Why is this? Well notice how 2n is even regardless of what integer n we pick. Raising any negative number to an even power results in a positive value.

Eg: (-7)^2 = 49 and (-3)^4 = 81

This means that all of the terms of sequence E are going to be positive. The terms do not bounce back and forth between positive and negative.

Put another way, [tex](-1)^{2n} = \left((-1)^2\right)^n = 1^n = 1[/tex]

So [tex]\displaystyle \sum_{n=0}^{\infty} (-1)^{2n}\frac{1}{n+3} = \sum_{n=0}^{\infty} \frac{1}{n+3}[/tex]

And it's why choice E is not one of the answers.

Answer:

X is equal to -10

Step-by-step explanation:

#1. Multiply 6 to (1+x). Doing this makes this equation: 6+x+x=-14

#2. Move 6 to the other side of the equation, to the side of the answer and change its abbsolute value. Doing this will make x+x=-14-6.

#3. Simplify both sides. 2x=-14-6  ---->  2x=-20

#4. divide -20 by 2, this equals -10. x is equal to -10. WooHoo!

Answer:

Answer x=-[tex]\frac{20}{7}[/tex]

Step-by-step explanation:

6(1+x)+x=-14

(multiply bracket with 6)

6+6x+x=-14

(-6 for both sides)

6x+x=-20

(add x terms together)

7x=-20

(divide by 7 for both sides)

x=-[tex]\frac{20}{7}[/tex]

Answer:

The right algebraic expression is 2x - 1

Step-by-step explanation:

Let us change the given phrase from words to mathematics expression

In our question, the phrase is " One less than twice a number "

To change it to an algebraic expression

→ Assume that the number is x

∵ Twice a number means 2 × x = 2x

∵ One less than twice the number means 2x - 1

∴ The algebraic expression is " 2x - 1 "

→ The error in the given expression is

The right algebraic expression is 2x - 1

Step-by-step explanation:I took the test too

Answer:

A) ∀ real numbers x and y, if xy = 0 then x = 0 or y = 0.

B)  ∀ real numbers x and y, if xy ≠ 0 then x ≠ 0 and y ≠ 0.

c) If neither of two real numbers is zero, then their product is nonzero

Step-by-step explanation:

A) Expression of zero product property using quantifiers and variables

    ∀ real numbers x and y, if xy = 0 then x = 0 or y = 0.

B)  Contrapositive of the zero product property

     ∀ real numbers x and y, if xy ≠ 0 then x ≠ 0 and y ≠ 0.

C) The Informal version (without quantifier symbols or variables) for the contrapositive of the zero product property is : If neither of two real numbers is zero, then their product is nonzero

Answer:

L(x) = 11 - 2x

W(x) = 8.5 - 2x

V(x) = 4x³ - 39x² + 93.5x

Step-by-step explanation:

If a square of x sides length is cut from each corner of the sheet, then it meas the length and width of the box a shortened by x inces from each side, giving a total subtraction of 2 times x inches.

FORMULA FOR LENGTH:

Since, Length is the bigger side of the box. Therefore, it will be taken on 11 inches side of the paper:

L(x) = 11 - 2x

FORMULA FOR WIDTH:

Since, width is the smaller side of the box. Therefore, it will be taken on 8.5 inches side of the paper:

W(x) = 8.5 - 2x

FORMULA FOR VOLUME:

Volume is the product of length, width and time:

V(x) = L(x)*W(x)*H(x)

Height must be equal to the side folds which are equal to length of the side of square = x:

H(x) = x

Therefore,

V(x) = (11 - 2x)(8.5 - 2x)(x)

V(x) = (93.5 -22x -17x + 4x²)(x)

V(x) = 4x³ - 39x² + 93.5x
