405 gallons of water in the tank in 45 minutes.
What is slope intercept form of line?The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
Given that A water tank is filled with a hose.
The table shows the number of gallons of water in the tank compared to the number of minutes the tank was
being filled.
The line of best for this data is g = 9m - 0.17.
We need to find when it is 45 minutes.
We have to put m value as 45 to find the number of gallons
g=9(45)-0.17
g=405-0.17
g=404.83
Hence, 405 gallons of water in the tank in 45 minutes.

12. The table of values below describes a quadratic relation. Find the missing value and include calculations that demonstrate that this is the correct value.
Answer:
The quadratic equation is;
y = 3x^2-7x + 5
when x = 4, y = 25
Step-by-step explanation:
Mathematically, the general form of a quadratic equation is;
y = ax^2 + bx + c
From the first point, we have that x = 0
Thus;
5 = a(0)^2 + b(0) +c
c = 5
Now, in a case when x is 2
3 = a(2)^2 + b(2) + 5
3 = 4a + 2b + 5
4a + 2b = -2 ••••••(i)
when x = 6
71 = a(6)^2 + b(6) + 5
66 = 36a + 6b ••••••(ii)
From equation i,
2b = -2-4a ••••(iii)
we can rewrite equation ii as
66 = 36a + 3(2b)
Substitute iii into ii
66 = 36a + 3(-2-4a)
66 = 36a - 6 - 12a
66 + 6 = 36a -12a
24a = 72
a = 72/24
a = 3
Recall;
2b = -2-4a
2b = -2-4(3)
2b = -2-12
2b = -14
b = -14/2
b = -7
So the quadratic equation would be;
y = 3x^2 -7x + 5
Now let us test;
when x = 10, y = 235
That would be:
y = 3(10)^2 -7(10) + 5
y = 300 - 70 + 5
y = 235
This shows that the derived quadratic equation is correct
Now, when x = 4; we have it that;
y = 3(4)^2 -7(4) + 5
y = 48 -28 + 5
y = 20 + 5 = 25

Han and Leila live 7 miles apart. They decide to start walking toward each other's houses at
the same time. Leila walks at a rate of 2.5 miles per hour and Han walks at a rate of 3 miles
per hour. How long will it take for them to meet?
2.5 + 3 = 5.5 total speed
7miles / 5.5 mph = 1.27 hours
Answer:
1.27 hours
Step-by-step explanation:
The first step in this process would be adding both rates of Leila and Han together. We know Leila walks at 2.5 miles per hour and Han at 3 miles per hour.
[tex]2.5 + 3 = 5.5[/tex]
We got our sum as 5.5, so now we must complete Step 2, which is the final step. We must divide 7 by 5.5.
[tex]7 / 5.5 = 1.2727...[/tex]
1.2727 ≈ 1.27
the answer to the Question is 1.27 hours.

17. A man stands 4300 feet from the Burj Khalifa in
Dubai (world's tallest building). The angle of
elevation from his eyes (5 feet) to the top of the
building is 32°. How tall is the building?
9514 1404 393
Answer:
b. 2692 ft
Step-by-step explanation:
The relation of interest between the sides of the right triangle is ...
Tan = Opposite/Adjacent
Using the given numbers, that is ...
tan(32°) = (building height)/(4300 ft)
Multiplying by 4300 ft, we get ...
building height = (4300 ft)·tan(32°) ≈ 2686.9 ft
This is the height above the observer's eyes, so the height of the building above the ground is ...
2687 +5 = 2692 . . . . feet
The building is 2692 feet tall.

Answer:
y = -1
Step-by-step explanation:
1) first, you would have to substitute x, the input, with 30, y = 14-0.5(30)
2) then, you would multiply 0.5 and 30 together which gets y=14-15
3) lastly, 14-15 equals -1 so y = -1
Answer:
Answer is -1
Step-by-step explanation:
First we know that x = 30, and in 0.5x we can plug in 30 because x = 30. So the equation is 14 - 0.5(30), now multiply 0.5 * 30 which will give you 15. Now the new equation is y = 14 - 15, 14 - 15 will give you -1. And that is y, Y = -1
