Vehicle A gets 39 miles per 1.5 gaons of fuel. How many miles could it get on 3.5 gallons of fuel
Answer:
91 miles
Step-by-step explanation:
Let's make a proportion
miles/gallons=miles/gallons
The vehicle gets 39 miles on 1.5 gallons, and x miles on 3.5 gallons
39 miles/1.5 gallon= x miles/3.5 gallons
39/1.5=x/3.5
Now, we need to solve for x. To do this, we have to get x by itself. x is being divided by 3.5 To undo this, multiply both sides by 3.5, because multiplication is the opposite of division.
3.5*39/1.5=x/3.5*3.5
The 3.5s on the right cancel, so we are left with:
3.5*39/1.5=x
3.5*26=x
91=x
The vehicle gets 91 miles on 3.5 gallons of fuel

If A has coordinates (2, –1) and B has coordinates (–1, 1), what are the coordinates of the midpoint of AB¯¯¯¯¯¯ ?
Answer:
The midpoint of AB is (0.5,0)
The coordinates of the midpoint of AB are (1/2, 0).
What is Midpoint?A midpoint is defined as in the middle of the line connecting two points a position known as a midpoint. A location in the middle of a line connecting the two points that are equally far from both points is the midpoint.
Let two points A (x₁, y₁) and B (x₂, y₂), the midpoint between A and B is given by,
M(x, y) = (x₁ + x₂)/2, (y₁ + y₂)/2
To find the midpoint of a line segment, we average the coordinates of the endpoints.
The x-coordinate of the midpoint is the average of the x-coordinates of A and B, which is:
(2 + (-1)) / 2 = 1/2
The y-coordinate of the midpoint is the average of the y-coordinates of A and B, which is:
(-1 + 1) / 2 = 0
Therefore, the midpoint of AB is (1/2, 0).

Answer:
The circumference of the horse pin is 150.86 feet
Step-by-step explanation:
In this question, we are to calculate the circumference of the horse pin, given that the diameter is 48 feet.
Mathematically, the circumference can be calculated using the formula
C = 2 * pi * r
where r = D/2 = 48/2 = 24 feet
The circumference C is thus = 2 * 22/7 * 24 = 1056/7 = 150.86 feet
To solve the system of linear equations 8 x + 5 y = 18 and 6 x + y = negative 2. by using the linear combination method, Amos decided that he should first multiply the second equation by –5 and then add the two equations together to eliminate the y-terms. His calculations are as shown. 8 x + 5 y = 18. + 6 x minus 5 y = 10. 14 x = 28. StartFraction 14 x Over 14 EndFraction = StartFraction 28 Over 14 EndFraction. X = 2. 6 x + y = negative 2. 6 (2) + y = negative 2. 12 + y = negative 2. 12 + y minus 12 = negative 2 minus 12. y = negative 14. Amos’s solution is (2, –14). What did he do wrong? He multiplied the equation 6 x + y = negative 2. by –5 incorrectly. He added the equations 8 x + 5 y = 18 and 8 x + 5 y = 18 incorrectly. He substituted 2 into the equation 6 x + y = negative 2. incorrectly. He solved the equation 12 + y = negative 2 for y incorrectly.
Answer:
(A)He multiplied the equation[tex]6x+ y = - 2[/tex] by –5 incorrectly.
Step-by-step explanation:
To solve the system of linear equations:
8 x + 5 y = 186 x + y = -2.Part of Amos' calculations is shown:
8 x + 5 y = 18.
6 x -5 y = 10.
When you multiply 6x+y =-2 by -5, we have the expression:
-30y-5y=10.This was not Amos' result as he got 6 x -5 y = 10.
Therefore, he multiplied the equation[tex]6x+ y = - 2[/tex] by –5 incorrectly.
The correct option is A.
3) The Morgan’s are replacing the flooring in their kitchen with ceramic tiles. They are deciding between 18 inches square tiles and 6 inches square tiles. What is the difference of the area of the two tiles they are considering?
with the 18 inch square tiles, you would cover an area of 324 in^2
with the 6 inch square tiles, you would cover an area of 36 in^2
The difference in area between an 18-inch square tile and a 6-inch square tile is 288 square inches.
The question revolves around the difference in area between two different sized ceramic tiles. To calculate the area of a tile, we use the formula Area = length imes width. Since tiles are square, the length and width are the same. For an 18-inch tile, the area is 18 inches × 18 inches, and for a 6-inch tile, it's 6 inches × 6 inches.
The area of the 18-inch tile is:
324 square inches (because 18 × 18 = 324)
The area of the 6-inch tile is:
36 square inches (because 6 × 6 = 36)
The difference in area between the two tiles is:
288 square inches (because 324 - 36 = 288).

0.40 x 25
and you get 10. so
10 members of the 25 are girls.
Hope that helped :))
The science club has 10 girls.
The question is asking us to calculate the number of girls in a science club where 40% of the members are girls. Since the science club has a total of 25 members, we would find 40% of 25 to determine the number of girls. To find 40% of a number, you multiply the number by the percentage expressed as a decimal. In this case, 40% is the same as 0.40.
So the calculation would be:
25 members x 0.40 = 10 girls
Therefore, there are 10 girls in the science club.
if xy=0, what must be true about either x or y
Answer:
either x or y must equal 0
Step-by-step explanation:
ts given that xy = 0
Remember that product of two numbers can be zero only if:
Both of them are zero or Either of them is zero as zero multiplied to any non-zero number will always be equal to zero. This is known as Zero Product Property.
So, if the product of x and y is equal to 0 there are two possibilities:
Both x and y are equal to 0
Either x or y must be equal to 0
Note that the condition both x and y are equal to zero is not a must condition, because even if one of them is equal to zero, the entire expression will be equal to zero.
Hence, the condition which has to be true in all cases for xy = 0 is:
either x or y must equal 0
Given that xy = 0.

Wyatt was cleaning his room and found 57 books under his bed he stacked the on his desk each stack had the same number of books in it and no stack had fewer than 5 books how many stacks did Wyatt make and how many books were in each stack
Answer:
19 books in 3 stacks
Step-by-step explanation:
57 divided by 3 equals 19
Wyatt could make either 19 stacks with 3 books each or 3 stacks with 19 books each, as these are the factors of 57 greater than 5.
The question is asking how many stacks of books Wyatt made if he found 57 books and placed them on his desk in stacks that all contained the same number of books, and each stack had no fewer than 5 books. We can solve this problem through the process of division, which involves dividing the total number of books by the number of books in each stack. To find out how many stacks Wyatt made and how many books are in each stack, we need to look for factors of 57 that are 5 or greater. The possible factors are 1, 3, 19, and 57. However, since each stack must have at least 5 books, the only feasible number of books per stack that will work are 3 and 19. Therefore, Wyatt could either make 19 stacks of 3 books each or 3 stacks of 19 books each.

A company charges $13 plus $3 per hour to rent a boat. Abigail and Monique want to rent a boat but do not want to spend more than $20 each. Which inequality below would represent how to find the maximum number of hours the girls can rent a boat?
Final answer:
Abigail and Monique can spend a maximum of $40 together for renting a boat. Given the company's pricing model, the inequality 3h ≤ 27 represents their situation, and solving it shows they can rent the boat for up to 9 hours.
Explanation:
The question is about calculating the maximum number of hours Abigail and Monique can rent a boat, given they each do not want to spend more than $20. The company charges a $13 flat fee plus $3 per hour for renting a boat. The total amount they are willing to spend each is $40 ($20 each), subtracting the flat fee leaves $27 to be spent on the hourly rate. Therefore, the inequality to find the maximum number of hours they can rent the boat is:
3h ≤ 27
Dividing both sides by 3 gives:
h ≤ 9
So, Abigail and Monique can rent a boat for a maximum of 9 hours.
A cylindrical feed silo has a diameter of 45 feet and a height of 30 feet. What is the volume of the largest sphere that will it into the game
A) 10677.9 Ft^ 3
B) 14,237.2 Ft^3
C) 42,711.6 Ft^3
D) 47,712 Ft^3
Answer:
The correct volume of the largest sphere that fits inside the silo is 14,137.2 ft³
Step-by-step explanation:
Since the sphere must feet inside the silo it's diameter must be at most 30 feet, therefore it's radius is 15 feet. To calculate the volume of the sphere we can use the appropriate formula:
Volume = (4/3)*pi*r³
Volume = (4/3)*3.14*(15)³
Volume = 14137.2 ft³
The correct volume of the largest sphere that fits inside the silo is 14,137.2 ft³. The nearest option would be B.
Final answer:
The volume of the largest sphere that can fit into the cylindrical feed silo is calculated using the formula for the volume of a sphere, resulting in 47,712 ft³, which corresponds to option D.
Explanation:
The question asks for the volume of the largest sphere that can fit into a cylindrical feed silo with a diameter of 45 feet and a height of 30 feet. To find the volume of the sphere, we need to consider the diameter of the cylinder because the diameter of the silo will be the same as the diameter of the sphere that can fit inside it. Hence, the radius of the sphere (and cylinder) is half of the diameter, which is 22.5 feet. The formula for the volume of a sphere is V = (4/3)πr³. Substituting the radius into the formula gives us V = (4/3)π(22.5)³ = 47,712 ft³.

A 2 m surfer is standing 12 m away from the lifeguard station. He wants to go to the Burger Shack for lunch. The Burger Shack is 14 m tall. How far away is it from the lifeguard station?
Answer:
72 meters
Step-by-step explanation:
If we take into account the relationship between the data of the problem, we have a relationship between heights and distances.
Between the height would be between the surfer and burger shack, and the known distance of 12 between the surfer and the lifeguard station.
we have the following relationship
2/14 = 12 / x
x = 14 * 12/2
x = 84
but this would be the distance between the surfer and burger shack, the distance we need would be:
84 - 12 = 72
it means that between burger shack and the lifeguard station there are 72 meters
