Answer:
[tex]96.25[/tex] minutes.
Step-by-step explanation:
The question states that it takes the larger hose [tex]55[/tex] minutes to fill the entire pool on its own. Assume that the larger hose fills the pool at a constant rate. What fraction of the pool would this hose fill in each minute?
The larger hose fills [tex]\displaystyle \frac{1}{55}[/tex] of the pool in each minute. That is: [tex]\displaystyle \frac{1\; \text{pool}}{55\; \rm \text{minutes}} = \frac{1}{55}\; \text{pool} \cdot \text{minute}^{-1}[/tex].
Similarly, assume that the smaller hose is also filling the pool at a constant rate. The question states that it takes [tex]35[/tex] minutes for the two hoses to fill the pool when working together. Therefore, when working together, the two hoses would fill [tex]\displaystyle \frac{1}{35}[/tex] of the pool in each minute. That is: [tex]\displaystyle \frac{1\; \text{pool}}{35\; \rm \text{minutes}} = \frac{1}{35}\; \text{pool} \cdot \text{minute}^{-1}[/tex]
The difference between these two fractions should represent the fraction of the pool that the smaller hose fills in each minute:
The smaller hose fills [tex]\displaystyle \left( \frac{1}{35} - \frac{1}{55} \right)[/tex] of the pool in one minute. That's [tex]\displaystyle \left( \frac{1}{35} - \frac{1}{55} \right)\; \text{pool} \cdot \text{minute}^{-1}[/tex].
At [tex]\displaystyle \left( \frac{1}{35} - \frac{1}{55} \right)\; \text{pool} \cdot \text{minute}^{-1}[/tex], filling the entire pool would take
[tex]\displaystyle \frac{1\; \text{pool}}{\displaystyle \left( \frac{1}{35} - \frac{1}{55} \right)\; \text{pool} \cdot \text{minute}^{-1}} = \frac{1}{\displaystyle \frac{1}{35} - \frac{1}{55}}\; \text{minute} = 96.25\; \text{minute}[/tex].
Hence, it would take [tex]96.25[/tex] minutes for the smaller hose to fill the entire pool on its own.

Given the scale factor R = 1/3, if AB = 12 cm, how ling is A’B’?
A. 36 cm
B. 3 cm
C. 8 cm
D. 15 cm
E. 4 cm
Answer:
E. 4 cm
Step-by-step explanation:
Given:
Scale factor (R) = [tex] \frac{m_{image}}{m_{preimage}} = \frac{1}{3} [/tex]
AB = 12 cm
Required:
Length of A'B'
SOLUTION:
A'B' = length of the image = x cm
AB = length of the preimage = 12 cm
Thus, using the scale factor given, the length can be calculated as shown below:
[tex] \frac{m_{image}}{m_{preimage}} = \frac{x}{AB} = \frac{1}{3} [/tex]
[tex] = \frac{x}{12} = \frac{1}{3} [/tex]
Multiply both sides by 12
[tex] \frac{x}{12}*12 = \frac{1}{3}*12 [/tex]
[tex] x = \frac{12}{3} [/tex]
[tex] x = 4 [/tex]
x = A'B' = 4 cm

To calculate the unit price of an item, divide the total number of units by the total price.
Please select the best answer from the choices provided
Answer:
False
Step-by-step explanation:
To calculate the unit price of an item, divide the total number of units by the total price is a "false statement." To calculate the unit price of an item, you have to understand that unit price means price per unit. To find the unit price we divide the total cost by the amount of items we are given in the question.
Example:
Sarah has 12 apples, she paid 20 dollars for all 12 apples, what is the unit price?
[tex]unitp=cost\div quantity[/tex]
[tex]unit=20\div12=1.66666667[/tex]
[tex]=1.66666667[/tex]
Round the answer to the nearest cent:
[tex]1.66666667[/tex]
[tex]6 > 5[/tex]
[tex]=1.67[/tex]
Which means the unit price of the 12 apples is "$1.67."

For what value of X must ABCD be a parallelogram?
Answer:
x = 9
Step-by-step explanation:
If ABCD is a parallelogram, then 6x = 7x - 9
as the point of intersection of the 2 diagonals is the midpoint of AC
6x = 7x - 9
Subtract 6x from both sides:
⇒ 0 = x - 9
Add 9 to both sides:
⇒ 9 = x
Solution:
We know that:
[tex]\frac{AC}{2} = 6x[/tex]This means that:
[tex]AC = (6x)(2) = 12x[/tex][tex]AC = 12x = 6x + 7x - 9[/tex]Step-by step calculations:
Simplify the RHS:
[tex]12x = 6x + 7x - 9[/tex]=> [tex]12x = 13x - 9[/tex]Subtract 13x both sides:
=> [tex]-13x + 12x = 13x -13x - 9[/tex]=> [tex]-x = -9[/tex]Divide -1 both sides:
=> [tex]-x = -9[/tex]=> [tex]\frac{-x}{-1} = \frac{-9}{-1}[/tex]=> [tex]x = 9[/tex]Which of the following is FALSE?
A. A midpoint divides a segment into two equal parts.
B. An angle bisector divides an angle into two equal parts.
C. All right angles are congruent.
D. Vertical angles are acute angles?
Answer:
D
Step-by-step explanation:
Vertical angles are just angles formed by intersecting lines, there is no rule that states they must be acute (they can also be right or obtuse)
The option that is False is that Vertical angles are acute angles.
What is the meaning of the term congruent?In mathematics, the term congruent means a figure, shape, or angle that has two equal parts, size, and length.
It is true that the midpoint of a segment refers to the line that splits the segment into two congruent(equal parts)Also, at any two equidistant points, an angle bisector divides an angle into two equal parts.All right angles are also congruent to one another.However, vertical angles assume a right angle and they are perpendicular to the straight line which makes them 90°, but we know that acute angles are angles that are less than 90°.
Therefore, we can conclude that vertical angles are not acute angles.

What is the surface area of a box with a length of 6 ft, a width of 3 ft, and a height of 2½ ft?
Answer:
Step-by-step explanation:
Remark
The surface area is the area of all six sides when the object is a box.
Formula
SA = 2*L*w + 2*L*h + 2*w*h
Givens
L = 6 ft
w= 3 ft
h = 2.5 feet
Substitute and Solution
SA = 2*6*3 + 2*6*2.5 + 2*3*2.5
SA = 36 + 30 + 15
SA = 81
Find the slope and the y-intercept of the graph of the linear equation.
Explanation
The given equation y = 2x+3 is in the form y = mx+b
Compare the terms to see that 2x matches with mx, so m = 2
The other term matches with b, so b = 3
m is the slope and b is the y intercept, so that's how I got those answers above.
