[tex] \sqrt[3]{686x {}^{4} } y {}^{7} [/tex]

Answers

Answer 1

The expression can be simplified as  [tex]7x\sqrt[3]{ 2x} y^7[/tex].

What is an expression?

An expression in mathematics is made up of numbers, variables, and functions (such as addition, subtraction, multiplication or division, etc.)

A phrase in language may contain an action on its own, but it does not constitute a whole sentence.

Given:

The expression = [tex]\sqrt[3]{686x^4} y^7[/tex]

Factorize 686 we get 7³ × 2

= [tex]\sqrt[3]{7^3\times 2x^4} y^7[/tex]

= [tex]7x\sqrt[3]{ 2x} y^7[/tex]

Therefore, the expression can be simplified as  [tex]7x\sqrt[3]{ 2x} y^7[/tex].

x + y - 3z = -20
-3y + 2z = 5
z = 4

Answers

Answer:

x= -9

y= 1

Step-by-step explanation:

-3y+2z=5

(put the value of z in the equation)

-3y+2(4)=5

-3y+8=5

8-5=3y

3=3y

y=3/3

therefore y= 1

x+y-3z=-20

(put the value of y and z in the equation)

x+1-3(4)=-20

x+1-12=-20

x+1= -20+12

x= -8-1

therefore x= -9

A rectangle has an area of 1008
square feet. Its width is six feet less
than twice the length. Find the
measures of the length and width of
the rectangle.

Answers

9514 1404 393

Answer:

length: 24 ftwidth: 42 ft

Step-by-step explanation:

The area is the product of length and width. If L represents the length, then the width is (2L -6), and the area is ...

  L(2L -6) = 1008

  L² -3L -504 = 0 . . . . . divide by 2, put in standard form

  (L -24)(L +21) = 0 . . . . factor

  L = 24 . . . . makes the first factor zero

  W = 2L -6 = 2(24) -6 = 42

The length of the rectangle is 24 feet; the width is 42 feet.

A.

= 6. Multiply both sides by 2. Ella's lunch cost $12.
B. 2x = 6. Divide both sides by 2. Ella's lunch cost $3.
C. x + 2 = 6. Subtract 2 from both sides. Ella's lunch cost $4.
O D. X-2 = 6. Add 2 to both sides. Ella's lunch cost $8.

Answers

Answer:

D

Step-by-step explanation:

Because it says Klay lunch cost is $2 less than Ella's.

==> Ella's - $2 = Klay's

==> x-2=6

plus both side by 2

When you're slicing parallel to the base, it would mean "in line" with the base if that makes sense. If we were to draw a line on where we would slice it, and another repersenting the base, neither line would ever touch.

So looking through each possible answer, if we were to slice each shape parallel to the base, only D would produce a circle.

Explanation:

In a standard deck of cards, there are 52 cards. They are broken down into suits (4 of them: Spades, Hearts, Diamonds, Clubs) of 13 cards each. Each suit has 13 ordinal cards (A, 2 through 10, Jack, Queen, King).

Here we're asked to draw a card at random and find the probability of drawing either a diamond or a 7.

With probability, we look at the fraction of ways we can achieve some condition (the numerator) over the number of ways we can do something (the denominator).

Our denominator here is 52 - the number of cards from which we can pull 1.

Our numerator is both all the diamonds, 13 cards, and all the sevens, 4 cards, but we need to subtract 1 to account for the double counting of the 7 of diamonds.

The probability of drawing a jack or ten from a deck of cards is 2/13.

The probability of drawing a jack or a diamond is 15/52.

How to calculate probability?

Fact: A deck of cards has 52 cards and in it:

13 cards of diamond13 cards of heart13 cards of clubs13 cards of spade

Another classification:

4 cards each of A,2,3,4,5,6,7,8,9,10,king,queen and jack And those 4 cards consist of a diamond, heart, club and spade card.

Now coming to the question:

We have 4 jack card and 4 10 cards, therefore total cards =8

Probability: Desired outcomes/total outcome

                  =8/52

                  =2/13

We have 13 diamond cards( in which 2 jack cards are already included) and another 2 jack cards.

therefore, total cards desired=13+2=15

Probability:15/52
