Jennifer chooses a playing card at random from a deck of 52 cards then she chooses another one. What is the probability that she will get 2 cards that are hearts?

Answers

Answer 1

Answer: 52 cards in a deck
4 suits
1/4 of 52 are hearts
1/4 of 52=13 cards

probability of getting 1 heart at first is 1/4

one card is taken out and assuming that it is the heart, 13-1=12,52-1=51
12/51

multiply
1/4 times 12/51=3/51=1/17

Answer 2

Answer: There is a $(13)/(52)$ chance she will pick a heart the first time and a $(12)/(51)$ that she will the second time.
The probability of this occurring thus is:
$(13)/(52)* (12)/(51) = (13*2*2*3)/(2*2*13*3*17)$
$= (1)/(17)$

Which equations have a negative solution?Choose all answers that are correct.

A. -w/2=11
B. -1/6x=-3
C.-4=v/(-10)
D. -3/4 2=8

Answers

A. w= -22 so A has a negative solution.D doesn't have a variable so I'm not sure about it (did you type it correctly?), but because only one side of the equation has a negative number, I'm guessing D is also a negative solution

The answer is A and D :)))))))))

The area of a rectangular field is 7007

yd2
. If the width of the field is
77
yards, what is its length?

Answers

The answer is 91
Length times width equals the area

area is length multiplied by width
if you have the area and the width you must divide so you can find the length
7007=77 times x
to find x divide by 77
x=91 so the length is 91

Calculate the area of triangle QRS with altitude ST, given Q (0, 5), R (−5, 0), S (−3, 4), and T (−2, 3).A- 6.2 square units

B- 7 square units

C- 5.9 square units

D- 5 square units

Answers

we have that

$Q (0, 5)\nR (-5, 0)\nS (-3, 4)\nT (-2, 3)$

using a graph tool

see the attached figure

the Area of triangle QRS is equal to

$A=(1)/(2)*b*h\n A=(1)/(2)*RQ*ST$

1) Find the distance RQ

Applying the formula of distance

$d=\sqrt{(y2-y1)^(2)+(x2-x1)^(2)}$

$dRQ=\sqrt{(0-5)^(2)+(-5-0)^(2)}$

$dRQ=√((25)+(25))$

$dRQ=√(50) units$

2) Find the distance ST

$dST=\sqrt{(3-4)^(2)+(-2+3)^(2)}$

$dST=√((1)+(1))$

$dST=√(2) units$

3) Find the area of triangle QRS

$A=(1)/(2)*RQ*ST\n\n A=(1)/(2)*√(50)*√(2) \n\n A=(1)/(2)*√(100) \n \n A=(10)/(2) \n \n A=5 units^(2)$

therefore

the answer is the option

D- $5$ square units

The correct answer among the choices provided is option D. The area of triangle QRS with altitude ST is 5 square units. To solve for the area, the distance formula was used. The formula was substituted with the given values, QR=√[(-5-0)²+(0-5)²].

carmine buys 8 plates for $1 each. he also buys 4 bowl. each bowl cost twice as much as each plate. the store is having a sale that gives carmine $3 off the bowls.which numerical expression shows how much he spent?

Answers

The numerical expression shows how much he spent will be $8 + $8 - $3 and its resultant is $13.

What is Algebra?

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

Carmine spends $1 on eight plates. Then the cost is given as,

⇒ 8 x $1

⇒ $8

He also purchases 4 bowls. The price of a bowl was double that of a plate. Then the cost is given as,

⇒ 4 x $2

⇒ $8

Carmine gets $3 off the bowls during the store's promotion. Then the numerical expression shows how much he spent will be given as,

⇒ $8 + $8 - $3

⇒ $13

The numerical expression shows how much he spent will be $13.
