To the nearest tenth, what is the distance between the point (10, -11) and (-1, -5)
The distance between the points (10, -11) and (-1, -5) is approximately 12.5 units.
Explanation:The distance between two points can be found using the Distance Formula.
The formula is:
distance = sqrt((x2 - x1)^2 + (y2 - y1)^2)
Using the given points (10, -11) and (-1, -5), we can plug the values into the formula:
distance = sqrt((-1 - 10)^2 + (-5 - (-11))^2)
distance = sqrt((-11)^2 + (6)^2)
distance = sqrt(121 + 36)
distance = sqrt(157)
To the nearest tenth, the distance is approximately 12.5 units.

What is the lcm of 1 and 5
Answer:
5
Step-by-step explanation:
The LCM of 1 and 5 is 5, as 1 is a factor of all numbers and thus does not change the other number when finding the LCM.
The least common multiple (LCM) of two numbers is the smallest number that is a multiple of both of the given numbers. In the case of 1 and 5, the LCM can be found by simply taking the larger number since 1 is a factor of all integers which therefore, gives the LCM of 1 and 5 as 5. There isn't really a need for a complex calculation because any number multiplied by 1 remains unchanged.
What is the least number of drops of red, blue, and yellow pigment that Ava
can add to a gallon of white paint so that the custom color consists of 25%
red, 35% blue, and 40% yellow pigment?
Answer:
5 red, 7 blue and 8 yellow
Step-by-step explanation:
Just make a ratio and simplify
Red : Blue : Yellow
25 : 35 : 40
All divisible by 5
5 : 7 : 8
These dont have a common factor so this is the simplest ratio
Therefore the minimum drops Ava can add to a gallon of white paint to have that ratio are 5 red drops, 7 blue drops and 8 yellow drops.
A bulletin board has a perimeter of 200 inches. Which equation expresses the area A(w) of the bulletin board as a function of its width, w?
A. A(w) = 100w - w2
B. A(w) = 200w - w2
C. A(w) = w2 – 100w
D. A(w)=w2 - 200w
The equation that expresses the area A(w) of the bulletin board as a function of its width w is A(w) = w².
Explanation:To express the area A(w) of the bulletin board as a function of its width, we need to find the equation that relates the width to the area. Since the perimeter of the bulletin board is given as 200 inches, we can use the formula for the perimeter of a rectangle: P = 2w + 2l, where w is the width and l is the length. Since the bulletin board is assumed to be a rectangle, the length is equal to the width. We can rewrite the formula as 2w + 2w = 200, which simplifies to 4w = 200. Solving for w, we find w = 50.
Now that we know the width, we can express the area A(w) as a function of w. Since the area of a rectangle is given by the formula A = length * width, and the length is equal to the width in this case, we have A(w) = w * w = w².
The correct equation that expresses the area A(w) of the bulletin board as a function of its width w is A(w) = w², which corresponds to option D.

The value of x is 27
Complete question and statement:
(4x + 7) = [5(x - 4)} what is the value of x?
Source: Previous question that can be found at brainly
Step-by-step explanation:
Let's solve for x, (4x + 7) = [5(x - 4)]
(4x + 7) = [5x - 20]
4x + 7 = 5x - 20
4x - 5x = - 20 - 7 (Subtracting - 5x and - 7 at both sides)
- x = - 27
x = 27 (Multiplying by -1 at both sides)
The value of x is 27

A 2-liter bottle of soda (67.6 ounces) costs $1.89. A case of twelve 12 ounce
cans of the same soda costs $2.99. Calculate the unit price (price/ounce) of each
item and determine which is the better bargain. Explain your answer.
Answer:
The two-liter bottle of soda has a unit price of $0.028/ounce.
The case of twelve 12 ounces has a unit price of $0.021/ounce.
The case of twelve 12 ounce can is the better bargain.
Step-by-step explanation:
A two-liter bottle of soda i.e. 67.6 ounces cost $1.89.
So, the unit price (price/ounces) of this type of soda is [tex]\frac{1.89}{67.6} = 0.028[/tex] dollars per ounce.
Again, a case of twelve 12 ounce cans of the same soda costs $2.99.
So, the unit price (price/ounces) of this type of soda is [tex]\frac{2.99}{12 \times 12} = 0.021[/tex] dollars per ounce.
Therefore, the case of twelve 12 ounce can is the better bargain. (Answer)

rick school is 30 miles from the hostipital. the school and hospital are 3/5inch apart on an online map.the hostipal is 4 inches from the airport on the map. hom far from the hostpital is the airport?
Answer: 200 miles
Step-by-step explanation: 1/5 is equal to 10miles so you 5/5 is 50 miles or 1 inch on the map.
Final answer:
The distance from the hospital to the airport on the map is 18 inches.
Explanation:
To find the distance from the hospital to the airport, we can use the scale of the map. Since the school and hospital are 3/5 inch apart on the map, and the school is 30 miles away from the hospital, we can set up the proportion:
3/5 inch = 30 miles
x inch = distance from hospital to airport
Cross-multiplying, we get 5x = 3 * 30
x = 18
Therefore, the distance from the hospital to the airport is 18 inches on the map.
Brianna's family spent $134 on 2 adult tickets and 3 youth tickets at an amusement park. Max's family spent $146 on 3 adults tickets and 2 youth tickets. What is the price of a youth ticket?
The price of 1 youth ticket is $ 22
Solution:
Let "y" be the price of 1 youth ticket
Let "a" be the price of 1 adult ticket
To find: price of 1 youth ticket
Brianna's family spent $134 on 2 adult tickets and 3 youth tickets at an amusement park
So we can frame a equation as:
2 adult tickets x price of 1 adult ticket + 3 youth tickets x price of 1 youth ticket = 134
[tex]2 \times a + 3 \times y = 134[/tex]
2a + 3y = 134 ---- eqn 1
Max's family spent $146 on 3 adults tickets and 2 youth tickets
So we can frame a equation as:
3 adult tickets x price of 1 adult ticket + 2 youth tickets x price of 1 youth ticket = 146
[tex]3 \times a + 2 \times y = 146[/tex]
3a + 2y = 146 ----- eqn 2
Let us solve eqn 1 and eqn 2 to find values of "y"
Multiply eqn 1 by 3
6a + 9y = 402 ---- eqn 3
Multiply eqn 2 by 2
6a + 4y = 292 ----- eqn 4
Subtract eqn 4 from eqn 3
6a + 9y = 402
6a + 4y = 292
( - ) -------------------
5y = 110
y = 22
Thus the price of 1 youth ticket is $ 22
Percy said that any real number for k would cause the system of equations to have no solution. Explain the error in Percy’s statement.
6x + 4y = 14,
3x + 2y = k
Answer:
Except k=7, any real number for k would cause the system of equations to have no solution.
Step-by-step explanation:
In general a system of equations can be represented as ax+by=c and dx+ey=f. In order this system of equations to have NO SOLUTIONS a/d=b/a≠c/f. In our example a=6, b=4, c=14, d=3, e=2 and f=k. To apply the formula above, 6/3=4/2≠14/k. Hence k≠7. It can be concluded that except k=7, any real number for k would cause the system of equations to have no solutions.
Just for information, if k=7 the system will have infinitely many solutions.
The error in Percy's statement is that, the system of equations would have infinite many solutions when k = 7
The system of equations is given as:
6x + 4y = 14,
3x + 2y = k
Multiply the second equation by 2
[tex]3x + 2y = k \to 6x + 4y = 2k[/tex]
Subtract the new equation, from the first equation
[tex]6x - 6x + 4y - 4y =14 -2k[/tex]
[tex]0=14 -2k[/tex]
Collect like terms
[tex]2k = 14[/tex]
Solve for k
[tex]k = 7[/tex]
The above means that:
The system of equations would have infinite many solutions when k = 7
