Solve the system.
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

Determine the probability of drawing either a jack or a diamond? Write your answer as a reduced fraction=

Answers

−

≈

0.3077

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

x × tan35° = 12 ( divide both sides by tan35° )

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.

Carlos is driving to Phoenix. Suppose that the remaining distance to drive (in miles) is a linear function of his driving time (in minutes). When graphed, the function gives a line with a slope of -0.85 . See the figure below.

Carlos has 60 miles remaining after 33 minutes of driving. How many miles were remaining after 25 minutes of driving?

Answers

Answer:

See below

Step-by-step explanation:

you have to use the equation y=mx+b

We know the slope is -0.85

we can plug in -0.85 for m to give us

y=-0.85x+b

Then we can use the 60 miles and 33 minutes by plugging them in for x and y

60=-0.85*33+b (multiply the numbers)

60=-28.05+b (add 28.05 to both sides to isolate the variable)

b=88.05

Then, use b with the slope and plug in the 25 minutes for x

y=-0.85*25+88.05

y= 66.8 miles

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.
