Answer:
2x + 5y = 4.70
Step-by-step explanation:
Rider ordered 2 hot dogs and 5 hush puppies. His total was $4.70. Write an equation in standard form for this relation, using
From the above question, note that
x = cost of a hot dog
y = cost of a hush puppy.
Our Standard Equation is given as
2 × x + 5 × y= $4.70
2x + 5y = 4.70
if the marginal revenue is higher than marginal cost the monopoly can increase profit by
Answer:
If the marginal revenue exceeds the marginal cost, then the firm can increase profit by producing one more unit of output. For example, at an output of 4 in Figure 3, marginal revenue is 600 and marginal cost is 250, so producing this unit will clearly add to overall profits.
There are 16 ties on each rack.
Write an equation to find the total number of ties.
(Let t = ties and r = racks.)

T(r) = (16 ties/racks)r
Step-by-step explanation:
Total number of ties = (16 ties/rack)(number of racks), or
T(r) = (16 ties/racks)r

Answer:
Hello! answer: 80
Step-by-step explanation:
What I did was find area of the shape all together without the cut out square and that was 96 because 12 × 8 = 96 then I found the area of the square 4 × 4 = 16 so I just subtract that by 96 and then thats are answer so...
96 - 16 = 80 so 80 is our area HOPE THAT HELPS!

Both circles have the same center. What is the area of the shaded region? r=10 m 7 m Use 3.14 for . Write your answer as a whole number or a decimal rounded to the nearest hundredth. square meters
Answer:
725.71 cm
Step-by-step explanation:
Using the attached diagram :
Diameter of inner circle = 26
Radius of inner circle = 26/2 = 13
Radius of entire circle = 13 + 7 = 20
The Area of a circle = πr²
Area of inner circle = π13² = 169π
Area of entire circle = π20² = 400π
Area of shaded portion :
Area of entire circle - Area of inner circle
400π - 169π = 231π = 725.71 cm
Otis is cutting a long piece of wood trim into smaller pieces for an art project. The line plot shows the length of the smaller pieces of wood. How many pieces of wood will be at least 1 2 foot in length?
Answer:
6
Step-by-step explanation:
From the line plot, the length of wood measuring atleast 1/2 in length include :
Piece with length 1/2 and pieces with length 2/3
Number of pieces with length 1/2 feets = 4
Number of pieces with length 2/3 feets = 2
Pieces with atleast 1/2 feet length = 4 + 2 = 6

Drag and drop the numbers 1 - 9 into the empty
boxes to the right to create a right triangle with the largest area
possible (round to the nearest TENTH, if necessary).
Each number can only be used one time, and only one number
can be placed per empty box (there will be some unused
numbers).
Answer:
9 for the hypotenuse, [tex]\sqrt{64}[/tex] and [tex]\sqrt{25}[/tex] for the two legs
Step-by-step explanation:
For these types of problems, we need to make sure that the values of legs are as big as possible while keeping the hypotenuse larger than legs because otherwise, it won’t be a right triangle.
So for the hypotenuse, we have to put the largest number in this number bank because the hypotenuse has to be larger than both legs. So the hypotenuse will equal 9. The rest is simple. Get the numbers as large as possible. Since the hypotenuse must be larger than both legs, we cannot use sqrt(81) and sqrt(64) (that would’ve been sweet). So we have to use sqrt(64) and sqrt(25) because sqrt(49) and sqrt(36) are already taken since we can only use a number once.
I'm not an expert at this and I cannot guarentee that this is correct. But I hope that this helps.

The options A,B,C and D
Now,
To order numbers and angles from least to greatest, you need to compare their values and arrange them in ascending order. For numbers, you can use a calculator1 or a number sorter2 to help you. For angles, you need to measure their size in degrees using a protractor3 and then classify them as acute (< 90°), right (= 90°), obtuse (> 90°) or reflex (> 180°) angles4. The smallest angle is an acute angle and the largest angle is a reflex angle.

Which of the following is likely to have the greatest variability? *
F. The cost of a piece of candy from a vending machine
G. The height of all the students at West Middle School
H. The age of all the students in the sixth grade
J. The number of days in a month
Answer:
G
Step-by-step explanation:
The most likely to have the greatest variability is,
⇒ The height of all students at West Middle school.
What is an expression?A Mathematical expression is defined as collection of the numbers, variables and functions by using operations like addition, subtraction, multiplication, and division
Now, We know that;
Greatest variability is large spectrum of possibilities.
Hence, We get;
The costs of candy from vending machine are going to be about the same price because they are all candy, so that does not vary much more.
And, The age of all the students in the sixth grade is going to be about the same because they are in the same grade.
Since, The number of days in a month is usually 31 or 30, so that also does not vary much.
This means, it has to be the height of all the students at West Middle school because it is a middle school so there are 3 different grades each having many students. This means that it will have the greatest variability.
Thus, The most likely to have the greatest variability is,
⇒ The height of all the students at West Middle school

Jared invests 10000 in a savings account that pays 3% simple interest how many years will it take for the account to grow to 12700 if he makes no withdrawals and deposits
Answer:
9 years
Step-by-step explanation:
Given data
Principal= $10000
Rate= 3%
Final amount= $12700
The simple interest expression is given as
A=P(1+rt)
substitute
12700=10000(1+0.03*t)
12700=10000+300t
collect like terms
12700-10000= 300t
2700=300t
divide both sides by 300
t= 2700/300
t= 9 years

Answer:
75
Step-by-step explanation:
Angles in a triangle add up to equal 180
That being said we can find the missing angle by subtracting the measures of the given angles from 180
Thus missing angle = 180 - 34 - 71
180 - 34 - 71 = 75
Which means that the missing angle = 75
Answer:
? = 180 - (angle 1 + angle 2)
? = 180 - (71 + 34)
? = 180 - 105
? = 75°
=> To check is the answer is right, add all 3 angles together and their sum should be 180°

If P(A) = 0.43 and P(
BA) = 0.89, find P(A and B).
Step-by-step explanation:
Me I don't know the answer teacher am waiting for the correction
The required probability of both A and B occurring is 0.3827.
What is probability?Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.
The conditional probability of A provided B has happened, so it can be written as follows:
P(B|A) = P(A and B)/P(A)
Given that P(A) = 0.43 and P(B|A) = 0.89
We can use the formula of conditional probability:
P(A and B) = P(B|A) × P(A)
Substitute the given values in the above formula,
P(A and B) = 0.89 × 0.43
P(A and B) = 0.3827
Therefore, the probability of both A and B occurring is 0.3827.

Two cards are drawn from a deck of 52 cards. What is the probability that the first card
drawn is a king and the second card drawn is a heart, given that the first card is
replaced? (Hint: A deck has 4 kings and 13 hearts)
Answer:
1) P(First card was a king) = 1/13 2.) 1/4
Step-by-step explanation:
1) P(First card was a king) = n(King)/n(Total) = 4/52 = 1/13
2. P(Heart)13/52 = 1/4
Answer:
1/52
Step by step explanation:
First, find the probability that the first card will be a King. Since there are 4 possible kings, and 52 cards, the probability is 4/52.
Then, find the probability that the second card will be a heart. "given that the first card is replaced" means that there are 13 possible hearts regardless of the suit of the first card. So 13/52 is the probability.
To find the probability of both occurrences, multiply them.
4/52 * 13/52 = 52/2704
52/2704 can be simplified to 1/52. So that is the probability that the first card will be a king and the second card will be a heart.
