Answer:
h(1.5) = 7.3 ft
h(10.3) = 24.9 ft
Step-by-step explanation:
Given the function h(d) = 2d + 4.3,
where:
h = height of the water in a fountain (in feet)
d = diameter of the pipe carrying the water (in inches)
h(1.5)Substitute the input value of d = 1.5, into the function:
h(1.5) = 2(1.5) + 4.3
h(1.5) = 3 + 4.3
h(1.5) = 7 feet
The height of the water in a fountain is 7 feet when the diameter of the pipe is 1.5 inches.
h(10.3)Substitute the input value of d = 10.3, into the function:
h(10.3) = 2(10.3) + 4.3
h(10.3) = 20.6 + 4.3
h(10.3) = 24.9 feet
The height of the water in a fountain is 24.9 feet when the diameter of the pipe is 10.3 inches.
Context of the solutions to h(1.5) and h(10.3):The solutions to both functions show the relationship between the diameter of the pipe to the height of the water in a fountain. The height of the water in fountain increases relative to the diameter of the pipe. In other words, as the diameter or the size of the pipe increases or widens, the height of the water in a fountain also increases.

In Texas, the coldest temperature ever recorded is
–
23°F. That's a lot chillier than in Florida, where the coldest recorded temperature is
–
2°F.
How many degrees warmer is Florida's coldest recorded temperature than Texas's?
°F
Answer:
I searched this and it said Florida's coldest temperature was -2°F and Texas's was -23. So the answer is 21.
Step-by-step explanation:
Texas's lowest temp: -23
Florida's lowest temp: -2
The difference is 21°F

Frankie works after school at the carwash. He makes $50 every pay period, plus a $10 commission (x) on each car he cleans. Choose the linear function that
represents his total pay each pay period (y).
Answer:
y = 10x + 50
Step-by-step explanation:
The island of Martinique has received $32000 for hurricane relief efforts. The island’s goal is to fundraise more than y dollars for aide by the end of the month. They receive donations of $4500 each day. Write an inequality that represents this situation, where x is the number of days.
Answer:
y=4500x+32000
Step-by-step explanation:
If they are increasing at a constant rate of 4500 then that is the coefficient of x, and if they received a 32000$ donation then that is the y-intercept so you add that to 4500x to get this equation.

Which table shows a proportional relationship between x and y
X
Answer:
The second one from the top
Step-by-step explanation:
This table shows a proportional relationship between x and y because when y is multiplied by 7, we get x.

what is the slope of the line // will give lots of points and brainliest
Answer:
1/2
Step-by-step explanation:
It usually works well to compute the slope from coordinates where the graph crosses grid line intersections. We can identify two of those as ...
(-1, 3) and (1, 4)
The slope formula tells you the slope is ...
m = (y2 -y1)/(x2 -x1)
m = (4 -3)/(1 -(-1)) = 1/2
The slope of the line is 1/2.

Additional comment
The y-intercept is 3 1/2.
An equation for the line could be ...
y = 1/2x + 3 1/2 . . . slope-intercept form
x -2y = -7 . . . . . . . . standard form

Answer:
The range is 13.
Step-by-step explanation:
The definition of the range is to subtract the largest number from the smallest number. Looking at this set of numbers, the largest number is 30, and the smallest number is 17. When you subtract 30 - 17 you end up with 13.

Step-by-step explanation:
Make 'y' the subject of the formula: 17t+3hy=24
Answer:
y=[tex]\frac{24-17t}{3h}[/tex]
Step-by-step explanation:
Hi there!
We are given the formula 17t+3hy=24
We want to make y the subject of the formula, which also means that we want to solve the equation for y
To do that, we'll need to isolate y on one side, much like solving for an equation with real numbers.
Let's first subtract 17t from both sides.
17t+3hy=24
-17t -17t
___________
3hy=24-17t
Now on the left, we have 3hy, but remember; we want just y by itself. Once again, similar to solving an equation with real numbers, we can pretend that 3h is the coefficient of the equation, while y is our variable.
So to get y by itself, we'll need to divide both sides by 3h
y= [tex]\frac{24-17t}{3h}[/tex], which can also be written as y=[tex]\frac{8}{h} -\frac{17t}{3h}[/tex]

Given the point (5, 6) and the slope of 5, find y when x = 21.
Answer:
y = 86
Step-by-step explanation:
We know the slope is 5 so we can write our equation like this:
y = 5x + b
Since we know that (5, 6) is on our equation, we can substitute it into our equation:
6 = 5(5) + b
b = 6-25 = -19
Now we know our equation is y = 5x - 19
Next, we plug in 21 for x to find our y-value:
y = 5(21)-19 = 105-19 = 86

a b and c are positive integers a:b
=3:8 and b:c=6:11
Answer:
a= 18; b= 48; c= 88. Please note that even half these value work (9, 24, 44) or any multiple of these (9k, 24k, 44k, with k a positive integer)
Step-by-step explanation:
Let's go easy, and pick b to be 6x8, to make things easy for us. Maybe even 6x4 could work, 12x8 will totally work, but this is the simplest choice.
Now on the first proportion [tex]a:48=3:8 \rightarrow 8a = 48\times3 \rightarrow a = 18[/tex]
From the second proportion [tex]48:c=6:11 \rightarrow 6c = 48\times 11 \rightarrow c = 88[/tex]

Find the cost per visit to the nearest cent: Health and Heart Club, $259 per year, 3 visits per week.
$7.19
$1.66
$3.32
$156
Answer: The answer is A $1.66
Step-by-step explanation: We have been given that Health and Heart Club charges $259 per year. A person has 3 visits per week. We are asked to find the cost of per visit to Health and Heart Club.We know that there are 52 weeks in one year. So total visits in one year would be 3 times 52 that 156 visits.
Now, we will divide total cost by 156 to find cost per visit.
Cost per visit = $1.660256
Rounding to nearest hundredths, we will get: Cost per visit = $1.66
Therefore, the cost per visit is $1.66 and option 'a' is the correct choice.

Graph: y–3=1/2(x+2)
Answer:
Step-by-step explanation:
Solve the y
y -3 = 1/2(x + 2)
y = 1/2(x + 2) + 3 Add
Pick points that you wish to substitute for x values.
x = 0 x = 2 x = 4
y = 1/2(x + 2) + 3 y = 1/2(x + 2) + 3 y = 1/2(x + 2) + 3
y = 1/2(0 + 2) + 3 y = 1/2(2 + 2) + 3 y = 1/2(4 + 2) + 3
y = 1/2(2) + 3 y = 1/2(4) + 3 y = 1/2(6) + 3
y = 1 + 3 y = 2 + 3 y = 3 + 3
y = 4 y = 5 y = 6
