Denelle draws one card from a standard deck of 52 cards. Determine the probability of drawing either a two or a queen.

Answers

Answer 1

Answer: There are four queens in a deck of cards, so the probability of drawing a queen is 4/52. There is also a 4/52 chance of drawing a two. Because you can draw either a two or Queen, you add the probability of each.

4/52 + 4/52 = 8/52

8/52 can be simplified to 2/13

the sum of two numbers is 44. the smaller number is 20 less than the larger number. what are the numbers?

Answers

sum means add
x and y are the numbers
sum i 44
x+y=44

smaller s 20 les than larger
x=20+y
or
y=20+x
doesn't matter, just pick one
x=20+y

substue 20+y for x since they are equal
x+y=44
(20+y)+y=44
20+y+y=44
20+2y=44
subtract 20 from both sides
2y=24
divide by 2
y=12
subsitue
x=20+y
x=20+12
x=32

the numbers are 12 and 32

x+(x-20)=44
2x= 64
x=32

Therefore the bigger number is 32 and the smaller number is 12
32+12=44

Translate the phrase into an algebraic expression. The sum of 9 and w

Answers

The algebraic expression for the sum of 9 and w is 9+x

Answer:9+w

Step-by-step explanation:

The sum of 9 and three times a number is 21. What is the number?equation:

n =

Answers

To solve equations like this we need to do inverse operations.

First we need to build an equation: 9+3x=21

We pass the nine to the other side, subtracting the 9 to 21, that leaves us with 3x=12

After that we just divide 12 by 3, wich gives us x=4, or, as it says in the question: n=4

Now let's double check:

N=4, since 3*4=12 and 12+9=21

Hope it is helpful :)

What is the distance from point -1, 6 To the line y=-2x

Answers

Answer:

Distance: 6.7

Step-by-step explanation:

y = -2x

If x is=0, y = 0 and if y is 0, x is = 2

(-1,6) and (2,0)

Sqrt[(2 - - 1)^2 + (0 -6)^2] =

Sqrt (3)^2 + (-6)^2 =

Sqrt 45 = 6.7

Answer:

distance from the point to the line is, d = 1.34

Step-by-step explanation:

equation of the line is, y = -2x

2x + y = 0

point given is, (-1, 6)

distance from the point to the line is given as,

d = |Ax1 + By1 + C| / √A² + B²

standard form of equation of line is:

Ax + By + C = 0

where, A = 2, B = 1, C = 0

and the point is, x1, y1 = -1, 6

by substituting the values in the formula,

d = |2(-1) + 1(-1) + 0| / √2² + 1²

= |-2 - 1 + 0| / √4 + 1

= |-3| / √5

= 3/2.24

thus, d = 1.34

Which of the following values of x makes the inequality true?x + 35 < 83

A. 53
B. 48
C. 51
D. 49

Answers

Hey there, subtract 35 from both sides would give you x<48, Therefore, the answer is B. 48

53 + 35 = 88
48 + 35 = 83
51 + 35 = 86
49 + 35 = 84
All these values are all greater or equal to 83. I'm pretty sure that all of these answers are incorrect... Unless you were supposed to make the < sign into a ≤...

A gardener weeds 2/3 of a flower bed in 6 min. How much of the flower bed did the gardener weed in 1 min?

(50 pts) (This is my own experiment 2 see how fast Brainly is and how efficient!)

Answers

(2/3 bed) / (6min) = ('x' bed) / (1min)

Cross-multiply:

(2/3 bed * 3min) = ('x' bed * 6min)

Divide each side by 6min:

1/3 bed = 'x' bed
