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

d. You can multiply cand 8
by in 1(c + 8) to find
an equivalent expression. True
False
Answer:
i don't think you can (but i could be wrong)
Step-by-step explanation:
my thinking is that since there is still an unknown variable even after you've multiplied that there can't be an equivalent expression
1(c+8)*8
=?
good luck :)

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

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)
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

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

Answer:
20 fl ounce = 1 pt and 4 fl oz
Step-by-step explanation:
We want to convert fluid ounce to pint and fluid ounce
Mathematically;
Mathematically, 1 pint = 16 fluid ounce
Now we can write 20 fluid ounce as;
16 fl ounce + 4 fl ounce
Since 16 fl ounce is a pint, we have it that;
20 fluid ounce is 1 pt 4 fl oz

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.
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

How do I solve this arithmetic sequence?
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

The high temperatures for the last seven days are: High Temperatures: 81, 78, 83, 89, 80, 87, 78
Find the MODE of the temperatures.
Answer: 78
Step-by-step explanation:
The mode is the number that appears the most number of times. In this case the number 78 appears twice unlike the other numbers that only appear once. Hence, 78 is the mode :)
Answer:
78
Step-by-step explanation:
The mode is the value that appears most often in a set of data. The mode of a discrete probability distribution is the value x at which its probability mass function takes its maximum value. In other words, it is the value that is most likely to be sampled.
y=2x+3 y=4x+7 solve by elimination
Answer:
[tex]\displaystyle [-2, -1][/tex]
Step-by-step explanation:
To use the Elimination method, you must get rid of one pair of variables, so that one side is set to zero. So, in this case, we must get rid of [tex]\displaystyle x,[/tex]therefore we will split the second equation in negative half :
[tex]\displaystyle \left \{ {{y = 2x + 3} \atop {-\frac{1}{2}[y = 4x + 7]}} \right. \\ \\ \\ \left \{ {{y = 2x + 3} \atop {-\frac{1}{2}y = -2x - 3\frac{1}{2}}} \right. \\ \\ \frac{1}{2}y = -\frac{1}{2}; -1 = y, -2 = x \\ \\ \\ \boxed{[-2, -1]}[/tex]

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
The right rectangular prism below is made up of 8 cubes. Each cube has an edge length of 12 inch.
Answer:
1 in³
Step-by-step explanation:
Complete question
The right rectangular prism below is made up of 8 cubes each cube has an edge length of 1/2 inch what is the volume of this prism
Volume of a cube = l³
If each cube has an edge length of 1/2 inch, then:
Volume of each cube = 1/2³
Volume of each cube = 1/8
Volume of the prism = 8×1/8
Volume of the prism = 1 in³
