Answer:
Initial temperature, temperature at time 0
Step-by-step explanation:
The temperature of water in degree Fahrenheit 1 minute after stove is turned on ;
W(0) = 72 ; Initial temperature od water, that is temperature when time, t = 0
W(5) > W(2) ; This will be true, the tperature after 5 minutes should be greater Than the temperature after 2 minutes
W(10) = 212 ; The temperature of water is 212 degree Fahrenheit after 10 minutes
W(12) = W(10)
e. W(15) > W(30)
A self-serve car wash charges $5.81 to use its facilities, plus an additional $0.51 for each minute the customer is at the self-serve car wash. If Tiffany was at the car wash for 5 minutes, how much was she charged?
Answer:
Tiffany was charged $8.36
Step-by-step explanation:
From the question, we can create the following equation where "c" is the amount of money she was charged, and "m" is the number of minutes Tiffany is in the car wash...
c = 0.51m + 5.81
Since in our case "m" equals 5, then...
c = 0.51m + 5.81
c = 0.51(5) + 5.81
c = 2.55 + 5.81
c = 8.36
Therefore Tiffany was charged $8.36

Two rectangles are similar. The first rectangle has a length of 15 cm and a width of 10 cm. The width of the second rectangle is 25 cm. What is its length?
Answer:
Its length is 37.5 cm.
Step-by-step explanation:
If two rectangles are similar, their sides are proportional, that is, they have equal ratios. So
The first rectangle has a length of 15 cm and a width of 10 cm. The width of the second rectangle is 25 cm.
So
[tex]\frac{15}{10} = \frac{l}{25}[/tex]
[tex]10l = 25*15[/tex]
Simplifying by 10.
[tex]l = 2.5*15 = 37.5[/tex]
Its length is 37.5 cm.

The perimeter of a rectangle can be found using the expression 2ℓ + 2w, where ℓ represents the length and w represents the width. Determine the perimeter if ℓ = 6 units and w = 3 units.
Answer:
18
Step-by-step explanation:
2(6) + 2(3)
12 + 6 = 18
The perimeter of the rectangle having a length of 6 units and a width of 3 units is 18 units.
What are the area and perimeter of a rectangle?The area of a rectangle is the product of its length and width.
The perimeter of a rectangle is the sum of the lengths of all the sides.
Given, The perimeter of a rectangle can be found using the expression
2l + 2w.
Also given that, the length is 6 units and the width is 3 units.
Therefore, The perimeter of this rectangle is,
= 2(6) + 2(3) units.
= 12 + 6 units.
= 18 units.

We have the expression [tex]\sqrt{x+4} -3=2[/tex] and are asked which is the first step to solve it.
When doing equations, you always want to isolate x, now since x is stuck in a square root, we need to first get rid of the numbers outside the root. So -3, we would need to add three to both sides first. This step crosses out all other answers and leave us with A.

Function p gives the perimeter of an equilateral triangle of side length s. It is represented by the equation p(s)=3x
a. What does P(s)=60 mean in this situation?
b. Find a value of s to make the equation P(s) = 60 true.
Answer:
A) p(s) means that the perimeter of the triangle is 60 units.
B) A value to make the equation true is s = 20
Step-by-step explanation:
In the equation p(s) = 60, 60 represents the perimeter of the equilateral triangle.
To find a value of s that makes the equation p(s) = 60 true, plug in 60 as p(s) and solve for s.
p(s) = 3s
60 = 3s
20 = s
So, s = 20 will make the equation true

please help lol
Answer:
Explanation below:
Step-by-step explanation:
To solve this problem you have to look at the three measurements (base x length x height), which are 7in, 3in, and 5in. For the top of the rectangular prism, the surface area is 21in (7in x 3in) and since the bottom is the same, the bottom is also 21in. Now that you have the top and bottom, let's look at the sides. The surface area for the long-sides is 35in (7in x 5in) and since both sides are the same, they are both 35. The surface area for the ends of the rectangular prism is 15in (5in x 3in) and since they are both the same, they are both 15in. Now that you have figured out what measurement goes with what, add all them up. (21in +21in) = 42in | (35in +35in) = 70in | (15in + 15in) = 30in
42in + (70in + 30in)
42in + 100in
The surface area for the entire shape is 142 inches.

Write two mixed numbers so that all rules are applied:
1. One number is larger than the other by 4 2/3
2. The difference of the numbers is equal to the smaller number.
3. The sum of the numbers is natural number
Answer:
Step-by-step explanation:
“One number is larger than the other by 4 2/3”
x = y + 4⅔
“The difference of the numbers is equal to the smaller number.”
x-y = y
x = 2y
y + 4⅔ = 2y
y = 4⅔
x = 2y = 9⅓
“The sum of the numbers is natural number”
