Answer: 2/3 books on politics
Step-by-step explanation:
The opportunity cost of something is the next best alternative that you would have taken if you did not instead go for the option that you took.
Opportunity cost here is the number of books on politics that Bill had to give up to get a single book on history.
= Number of politics books / Number of history books
= 4 / 6
= 2/3 books on politics
Bill gave up 2/3 books on politics to get a single history book.

In the game “Sandwich” three cards are dealt from a 52-card deck. To win, the value of the third card must be between the first two cards. What is the probability of winning given the first two cards dealt are a 6 and a 10?
Show ALL work!!!
Answer:
[tex]\frac{3}{13} ,\frac{12}{52}[/tex]
Step-by-step explanation:
In a 52 card deck there a 4 of ech individual card
There are 3 card values between 6 and 10, (7,8,9)
[tex](3)(4)=12[/tex]
12 out of the 52 cards could win the game, so there is a probability of

Two functions are graphed on the coordinate plane.
On a coordinate plane, a curved line with an upward arc, labeled g of x, crosses the x-axis at (negative 2, 0), and the y-axis at (0, 4). A straight horizontal line, labeled f of x, crosses the y-axis at (0, 4).
Which represents where f(x) = g(x)?
f(4) = g(4) and f(0) = g(0)
f(–4) = g(–4) and f(0) = g(0)
f(–4) = g(–2) and f(4) = g(4)
f(0) = g(–4) and f(4) = g(–2)
Answer:
Answer:
(B) f(-4)=g(-4) and f(0)=g(0)
Step-by-step explanation:
From the given graph, the lines f(x) and g(x) intersects at two different points.
When x=-4, f(-4)=4 and g(-4)=4
When x=0, f(0)=4 and g(0)=4
Therefore, the points which represent where f(x)=g(x) are:
f(-4)=g(-4); and
f(0)=g(0)
The correct option is B.

Question : If you are given the decimal division problem 7.89 ÷ 3 and find that the answer is 2.63, how can you use multiplication to check that your answer is correct? (What numbers would you have to multiply together?)
Use the expression 5a – 2b – 3 + 2b – 6a.
Part A
Simplify the expression.
–4
2a – 4b
–a – 3
a – 3
Part B
Which of the following is an equivalent expression?
–(3 + a)
–a + 3
–(a – 3)
–3 + a
Answer:
5a + (-6a) + (-2b) + 2b + (-3) = -a -3 or -(a + 3) so first answer is correct because -(a + 3) is the same as -(3 + a)

Isabella and her cousin Rodrigo have the same birthday but isabella is 15 years older than Rodrigo the equation y= x + 15 represents isabella's age y, when Rodrigo is x years old what is the answer?.
Answer:
The answer is below
Step-by-step explanation:
Isabella and her cousin rodrigo have the same birthday, but isabella is 15 years older than rodrigo is x years old. which table of value shows this relationship
Solution:
Let x represent Rodrigo's age and let y represent Isabella's age. Since Isabella is 15 years older than Rodrigo, hence her age is given by the equation:
y = x + 15
You can use a table to represent the relationship between their ages. Let us find the corresponding Isabella age for the following Rodrigo age.
Rodrigo: 10 20 30
Isabella: 25 35 45
When x = 10: y = x + 15 = 10 + 15 = 25
When x = 20: y = x + 15 = 20 + 15 = 35
When x = 30: y = x + 15 = 30 + 15 = 45
Use the distributive property to find the value of x.
-1.2(3 – x) = -1.8
-3.6 + 1.2x = -1.8
1.2x = 1.8
X= ?
Answer:
1.5
Step-by-step explanation:
-1.2(3-×)=-1.8
-3.6+1.2×=-1.8
1.2×=3.6-1.8
1.2×=1.8
1.2/1.2×=1.8/1.2
×=1.5

{33, 39}
The set {126, 168, 189} has 21 as a common factor.
The set{154, 231} has 11 as a common factor.
Common factor:If a number m is completely divisible by number n. Then number n will be the one factor of number m.
(a). Given set of number is, {126, 168, 189}
Now check, 21 is a common factor or not.
[tex]\frac{126}{21}=6,\frac{168}{21}=8,\frac{189}{21}=9[/tex]
It is observed that all numbers are completely divisible by 21.
So that , 21 is common factor.
(b). Given set of number is, {154, 231}
[tex]\frac{154}{11}=14,\frac{231}{11}=21[/tex]
It is observed that all numbers are completely divisible by 11.

The smiths bill at a restaurant is $85 how much money should Mr. Smith leave as a tip if he plans to tip 20%
Answer:
102.00
Step-by-step explanation:
If you want to leave a 20% tip, multiply the cost by 0.20 to get the tip amount or multiply the cost by 1.20 to get the total including tip. If you want to leave a 18% tip, multiply the cost by 0.18 to get the tip amount or multiply the cost by 1.18 to get the total including tip.
Answer: Mr. Smith should tip $17
Step-by-step explanation:
20% = 0.2
$85 × 0.2 = $17

What is the area of a parallelogram that has a base of 12 inches and a height of 8 inches?
Question 1 options:
96 square inches
1.5 square inches
20 square inches
Answer:
96 square inches
Step-by-step explanation:
Given in a parallelogram
base (b) = 12 inches
height (h) = 8 inches
Now
Area of parallelogram
= b * h
= 12 * 8
= 96 square inches
Hope it will help :)
Answer:
96
Step-by-step explanation:
Area= base x height
= 12 x 8
= 96
Since Area of parallelogram is base into height
Tell whether the ratios form a proportion. 30/75, 24/60
Given:
The ratios are [tex]\dfrac{30}{75}[/tex] and [tex]\dfrac{24}{60}[/tex].
To find:
Whether the ratios form a proportion or not.
Solution:
If two ratios represent the same relationship then they form a proportion.
We have,
[tex]\dfrac{30}{75}[/tex] and [tex]\dfrac{24}{60}[/tex]
Write the given ratios in the simplified forms.
[tex]\dfrac{30}{75}=\dfrac{15\times 2}{15\times 5}[/tex]
[tex]\dfrac{30}{75}=\dfrac{2}{5}[/tex]
And,
[tex]\dfrac{24}{60}=\dfrac{12\times 2}{12\times 5}[/tex]
[tex]\dfrac{24}{60}=\dfrac{2}{5}[/tex]
Since [tex]\dfrac{30}{75}=\dfrac{24}{60}=\dfrac{2}{5}[/tex], therefore the ratios form a proportion.
Simon set up his tent in his backyard last night. His tent is 6 feet tall. To secure it to the ground, he attached a rope from the top of the tent to the ground 8 feet away from the bottom of the tent as shown below. How many feet long, R, is the rope?
Length of Simon's tent = 6 feet
Distance from the bottom of the tent to the tent's base = 8 feet
Let the length of rope be R.
The tent and the rope forms a right angle triangle where the rope is the hypotenuse.
We know that :
[tex]\color{hotpink} \tt{hypotenuse}^{2} \color{plum}= {base}^{2} + {height}^{2} [/tex]
Which means :
[tex] = \tt {R}^{2} = {6}^{2} + {8}^{2} [/tex]
[tex] =\tt {R}^{2} = 36 + 64[/tex]
[tex] = \tt {R}^{2} = 100[/tex]
[tex] =\tt R = \sqrt{100} [/tex]
[tex]\hookrightarrow\color{plum}\tt \bold{R = 10 \: feet}[/tex]
Thus, the hypotenuse of this triangle = 10 feet
▪︎Therefore, the length of the rope = 10 feet

Answer:
64.428
Step-by-step explanation:
well to find the mean we add all of the numbers up and then divide it by the amount of numbers in the sequence
so if we add all of the numbers up it will give us
451
then if we divide that by the number of numbers in the sequence which is 7 then that will leave us with
around 65 or exactly it would be

Answer:
1. 2x +2y = 310; x -y = 55
2. y = 50, x = 105
Step-by-step explanation:
Let the numbers be represented by x and y. Double the numbers would give 2x and 2y. We're told the sum of the doubled numbers is 310, so one equation is ...
2x + 2y = 310
The difference of the numbers is (x-y). We're told that difference is 55, so the other equation is ...
x - y = 55
__
We can divide the first equation by 2, and subtract the second.
1/2(2x +2y) -(x -y) = 1/2(310) -(55)
2y = 100 . . . . . . . simplify
y = 50 . . . . . . . . . divide by 2
x -50 = 55 ⇒ x = 105 . . . . use the second equation to find x
The two numbers are 105 and 55.
