A card is drawn at random from a well-shuffled deck of 52 cards. what is the probability of drawing a face card or a spade?​

Answers

Answer 1

Answer:

2/5 or 2:5

Step-by-step explanation:

Face Card:

The face cards in a deck are the Jack, Queen, and King. There are 4 of each card (1 in each suit), for a total of 12 face cards.

Spade:

1/4 of all the cards in a deck are spades, so 52/4= 13 spades.

When added, the numerator of the probability is 25, however, because the Jack, Queen, and King of Spades are duplicated, we have to subtract 3.

25-3=22

22/55

when simplified: 2/5

It costs $3.95 to print a 12 in. by 16 in. color page. A friend needs to print a poster that is twice as long and twice as wide. At this rate, how much would he expect
to pay for the poster?

Answers

Answer:

$7.90

Step-by-step explanation:

Its is double both so u double $3.95

Price is determined by total area. The area of the original page is 192. If you calculate the area of the expanded posted, it would be 24*32. Which is 768. Find the scale factor of the areas, 768/192 is 4. 4*3.95 = 15.8. The price would be 15.80$.

Answers

$6.89

The book is $10. Minus the 35% discount ($10X0.35=$3.50). So the subtotal is $10-$3.50=$6.50.

Tax is 6%. So 0.06X$6.50=$0.39

The total including tax is $6.50+$0.39=$6.89

can someone help me with this please^

Answers

Answer:

a) 126degrees

b) 47degrees

Step-by-step explanation:

The sum of two supplementary angles is 180 degrees.

Let the other angle be x

x  + 54 = 180

x = 180 - 54

x = 126degrees

The supplement is 126degrees

b) The sum of two complementary angles is 90 degrees.

Let the other angle be y

y  + 43 = 90

y = 90 - 43

y = 47degrees

Hence the complement is 47 degrees

How do I solve this arithmetic sequence?

Answers

Answer:

The 16ᵗʰ term of this sequence is 82

Step-by-step explanation:

Here,

First Term = a₁ = 9

Common Difference = (d) = 2

Now, For 16ᵗʰ term, n = 16

aₙ = a + (n - 1)d

a₁₆ = 7 + (16 - 1) × 2

a₁₆ = 7 + 15 × 5

a₁₆ = 7 + 75

a₁₆ = 82

Thus, The 16ᵗʰ term of this sequence is 82

Mr. McGill is solving the following problem: 42x=163. Mr. McGill set 2x=3 and got x=32 as his answer. Tell the mistake Mr. McGill made and tell the correct answer.

Answers

Answer:

The mistake McGill made was to eliminate 4 and 16 from both sides before solving fro x

Step-by-step explanation:

Given the expression

42x = 163

To get the values of x, we are to divide both sides by the coefficient of x i.e 42 as shown;

42x = 163

42x/42 = 163/42

x = 163/42

x = 3.88

Hence the mistake McGill made was to eliminate 4 and 16 from both sides before solving fro x

If p(x)=x^2+x+1 and Q(x)=5x^2-1, find the following

1. Q(4)
2.p(-4)
3.p(1/2)

Answers

Answer:  1. 79

2.  13

3.  7/4

Step-by-step explanation:

Q(x)=5x^2-1

Q(4)=5(4)^2-1

      =5(16)-1

      =80-1

 Q(4) = 79

p(x)=x^2+x+1

p(-4)=(-4)^2+(-4)+1

      =16-4+1

 p(-4) =13

p(x)=x^2+x+1

p(1/2)=(1/2)^2+(1/2)+1

       =1/4+1/2+1

       2+4+8/9

        =14/8

p(1/2)    =  7/4

The solution is acute angles

Answer:

x = 4, y = -3

Step-by-step explanation:

Find the slope intercept form first (y = mx + b):

the one going down is y = -1/2x - 1 (slope is negative, down 1 over 2, and the y-intercept is at (0, -1) )

the one going up is y = 1/4x - 4 (slope is up 1 over 4, and the y-intercept is at (0, -4)

Convert them into standard form (Ax + By = C):

1st equation: multiply the entirety of both sides by 2 to get rid of the fraction:

2y = -1x -`2

add 1x to both sides: 1x + 2y = -2

2nd equation: multiply the entirety of both sides by 4 to get rid of the fraction:

4y = 1x - 16

subtract 1x from both sides: -1x + 4y = -16

Isolate a variable:

-x + 4y = -16

-x = -4y - 16

x = 4y + 16

Plug that into other equation:

1(4y + 16) + 2y = -2

6y + 16 = -2

6y = -18

y = -3

Substitute y into the isolated equation:

x = 4(-3) + 16

x = -12 + 16

x = 4

A box has a surface area of 450 cm². Its length and width are 6 and 8 respectively. What is its height?

Answers

Answer:

9.4 cm

Step-by-step explanation:

Given: Box; Length = 6 cm, Width = 8 cm, Surface area = 450 cm²

To Find: Height

Solution:

Divide the volume by the product of the length and width to calculate the height of a rectangular object.

                                                       6 × 8 = 48

                                                      450 ÷ 48 = 9.4

For this box, the rectangular object has a length of 6 cm, a width of 8 cm, and a volume of 450 cm². The product of 6 and 8 is 48, and 450 divided by 48 results in 9.4.

The height of the object is 9.4cm.
