left on together, the cold and hot water faucets of a certain bathtub take 8 minutes to fill the tub. If it takes the hot water faucet 18 minutes to fill the tub by itself how long will it take the cold water faucet to fill the tub on its own
The time taken to fill the bathtub by cold water is 14.4 minutes.
Given,
Time taken to fill a bathtub by both cold and hot water = 8 minutes
Time taken to fill the bathtub by hot water = 18 minutes
Time taken to fill the bathtub by cold water = t minutes
We have to find t.
We can take the full bath tub as 1.
Now,
We can equate the given data:
We get,
(8/18) + (8/t) = 1
Now, solve the equation:
((8 × t) + (8 × 18) ) ÷ (18 × t) = 1
(8t + 144) ÷ 18t = 1
8t + 144 = 18t
18t - 8t = 144
10t = 144
t = 144/10
t = 14.4
That is,
The time taken to fill the bathtub by cold water is 14.4 minutes.

The following table shows the profit rates for Nike and Adidas
Nike -2 (x - 2)
Adidas -17 + x
If x represents the number of shoes purchased, how many shoes have to be purchased until both companies earn the same amount? Create and solve the equation.
The number of shoes that have to be purchased until both companies earn the same amount is 21.
How to calculate the number of shoes?Based on the information, the profit rates for Nike and Adidas are illustrated as:
Nike -2 (x - 2)
Adidas -17 + x
In this case, x represents the number of shoes purchased,
The number of shoes that have to be purchased until both companies earn the same amount will. be:
2(x - 2) = 17 + x.
2x - 4 = 17 + x

Reynado ordered 12 large pepperoni pizzas. The total cost was $101.40. Write a direct variation function for the cost of one large pepperoni pizza. How much would 5 large pepperoni pizzas cost?
Answer:
(1) y = 8.45x
(2) Total cost: $42.25
Step-by-step explanation:
Let's see by constructing a first-hand example of the information we have.
$101.40 = 12x
Divide 12 on both sides.
When we divide 12 from both sides, we get the simplified answer of:
x = 8.45
This means that each pizza will be $8.45 each, therefore this will be out=r equation
y = 8.45x
(where x is the number of pizzas and y is the total amount cost.
To find the cost of 5large pepperoni pizzas, we use our equation above (y = 8.45x) and input a 5 in x;
y = 8.45(5)
y = 42.25
The total cost for the 5 pizzas will be $42.25.

Given f(x) = 3(4-x), what is the value of f( − 2)? Enter your answer in the answer box.
Answer:
f(-2) = 18
Step-by-step explanation:
In order to calculate a function of x, we replace x
For example
f(x) = x
f(-2) = -2
In this specific scenario
f(x) = 3 * (4 - x)
f(-2) = 3 * (4 - -2)
- -2 turns positive
f(-2) = 3 * (4 + 2)
Now we use PAMDAS (parentheses, exponents, multiplication, division, addition) as an operation order, so we first solve the parantheses
f(-2) = 3 * 6
f(-2) = 18

7/21, 7/18, 7/14, 7/12, and 7/8
2/12, 2/10, 2/8, 2/6, and 2/4.
Step-by-step explanation:
the order would be 2/17, 8/17, and 11/17 since the bottom number (denominator) stays the same while the numerator (top number) increases.
the order for the 2nd one would be:
7/21, 7/18, 7/14, 7/12, and 7/8. The reason for this is that when the numerator stays the same and the denominator increases, the value of the fraction decreases. For example, 1/2 is greater than 1/4, and 1/4 is more than 1/5 because 5 is greater than 4. This only works when the numerator (top number) stays the same.
The order for the 3rd one would be:
2/12, 2/10, 2/8, 2/6, and 2/4. Again, the numerator stays the same while the denominator changes. As the denominator goes down, the value of the fraction goes up.

Where does the line through (1, 0, 1) and (4, −4, 4) intersect the plane x + y + z = 6?
The line through (1, 0, 1) and (4, −4, 4) intersect the plane x + y + z = 6 at point (7,-8,7).
As given,
Equation of the line passes through two points (1, 0, 1) and (4, −4, 4) is:
[tex]\frac{x-4}{4-1}=\frac{y+4}{-4-0}=\frac{z-4}{4-1}[/tex]
From the above equation we have
(x-4)/3 =(y+4)/-4
⇒-4x+16= 3y+12
⇒y=(-4x +4)/3 __(1)
And
(x-4)/3=(z-4)/3
⇒z=x __(2)
Substitute the value of y and z in the plane x +y+ z=6 to get point of intersection of line and plane
x+ [(-4x +4)/3] +x=6
⇒3x-4x+4 +3x =18
⇒2x=14
⇒x=7
Substitute value of x in (1) and (2)
y=-8 and z=7

What is dilation?Dilation involves enlarging or reducing the side length of a shape to create another shape by a constant scale factor, where the scale factor does not equal one.
How to determine the location of P' and R' in the figure?The figure that completes the question is added as an attachment
From the figure, we have the following parameters
Center of dilation = Point CLength CR = 2.6 unitsLength PR = 5 unitsScale factor of dilation = 3The image of dilation using the above parameters is the scaled factor of the given figure
As a general rule, the following are the properties of a scaled copy of another figure
If the scale factor is greater than 1, the side lengths would be greater than the original figureIf the scale factor is less than 1, the side lengths would be less than the original figureThe angles of both figures are the sameThe side lengths may or may not be whole numbersThe above means that
New lengths = Old lengths * Scale factor
So, we have
P'R' = PR * Scale factor
C'R' = CR * Scale factor
This gives
P'R' = 5 * 3
P'R' = 15
C'R' = 2.6 * 3

A point that lies in the middle of a line and is equally spaced from its ends is the line's midway. The formula for the line's midpoint is [(x)1 + (x)2]/2, [(y)1 + (y)2]/2 if the line's endpoints are (x)1, (y)1, and (x), (y), respectively.
Explain about the midpoint?Using the equations [(x)1 + (x)2]/2, [(y)1 + (y)2]/2, one may get the midway. Here, the coordinates of two points are (x), (y), (x)2, (y)2, and the midway is a location that is equally spaced from both of these positions.
The exact middle number between two numbers is referred to as the midway. The midpoint calculation is the same as the two-number average calculation. Therefore, by adding any two numbers together and dividing by two, you may find the halfway between any two integers.
The distance formula, which is derived from the Pythagorean Theorem, is employed to determine the separation between two points in the plane. The Pythagorean Theorem is based on a right triangle where the angles are a and b.
