Answer: You are incorrect, the slope is correct, but the actual y-intercept is 205 ft.
Then the equation is:
y = (-15 ft/min)*x + 205 ft
Step-by-step explanation:
Ok, let's solve this.
We know that water is drained from a reservoir, let's assume that we can model this situation with a linear relation:
y = a*x + b
Where x is time, y is the height of the water in the reservoir, a is the slope (in this case represents how much changes the height of the water in the reservoir in one unit of time) and b is the initial height of the water in the reservoir.
We know that for a line that passes through the points (x₁, y₁) and (x₂, y₂) the slope is:
a = (y₂ - y₁)/(x₂ - x₁)
For this particular case we know that after 2 minutes the height of the water is 175 ft, then we have the point (2 min, 175 ft)
and after 5 minutes (so 7 minutes in total), the height of the water is 100ft, then: (7 ft, 100ft)
Then the slope of this:
a = (100 ft - 175 ft)/(7 min - 2 min) = (-75ft/5min) = - 15 ft/min
Then our line is something like:
y = (-15ft/min)*x + b
To find the value of b, we can use the fact that when x = 2 min, y = 175 ft
So if we replace these two values in the equation we get:
175ft = (-15 ft/min)*2 min + b
175 ft = -30 ft + b
175 ft + 30 ft = b
(here is your problem, it seems like you subtracted instead of adding in this part)
205 ft = b
Then the equation is:
y = (-15 ft/min)*x + 205 ft
So you are incorrect (but only for a little bit), you computed wrong the y-intercept.

9514 1404 393
Answer:
yes
Step-by-step explanation:
The side lengths of the triangle are 5, 12, and 5+8 = 13. We can check to see if they satisfy the Pythagorean theorem, which would indicate a right triangle.
5² + 12² = 25 +144 = 169 = 13²
These sides do satisfy the relationship between sides for a right triangle, so angle A is a right angle. That is the case when segment AB is a tangent to the circle.
Yes, AB is a tangent.

An ice block is in the shape of a rectangular prism. Danny cute the block so that each side is 1/2 it's original length. How do the volumes of the ice block compare
Answer:
After he cuts the blocks, the volume is one eight of the original.
Step-by-step explanation:
Volume of a rectangular prism:
The volume of a rectangular prism with dimensions abc is given by:
[tex]V = abc[/tex]
Danny cute the block so that each side is 1/2 it's original length. How do the volumes of the ice block compare?
This means that:
[tex]a = \frac{a}{2}, b = \frac{b}{2}, c = \frac{c}{2}[/tex]
So
[tex]V_c = \frac{a}{2}*\frac{b}{2}*\frac{c}{2} = \frac{abc}{2^3} = \frac{abc}{8} = \frac{V}{8}[/tex]
After he cuts the blocks, the volume is one eight of the original.

Step-by-step explanation:
10.) Your dad is planning to increase the area of your rectangular patio. Your current patio is 8
feet by 10 feet, and your dad plans to double its area by adding the same amount x to its length
and width. Find the value of x, and the new dimensions of the patio.
Answer:
x = 3.69 feet
11.69 x 13.69 feet
Step-by-step explanation:
new area = (8 x 10) x 2 = 160
(8 + x)(10 + x) = 160
80 + 8x + 10x + x² = 160
combine like terms:
x² + 18x - 80 = 0
factor:
(x - 3.69)(x + 21.69) = 0
x = 3.69
Answer:
x = 3.69 feet
11.69 x 13.69 feet
new area = (8 x 10) x 2 = 160
(8 + x)(10 + x) = 160
80 + 8x + 10x + x² = 160
combine like terms:
x² + 18x - 80 = 0
factor:
(x - 3.69)(x + 21.69) = 0
x = 3.69

Marco's goal is to eat only 2000 calories each day. One day for breakfast he consumed 310 calories, for lunch he consumed 200 more calories then breakfast, and for dinner he consumed 800. Did he make his goal? Explain
Answer:
no
he consumed only 1620 calories
Step-by-step explanation:
WE HAVE TO FIND THE SUM OF THE TOTAL CALORY
CALORIES CONSUMED IN THE MORNING = 310
CALORIES CONSUMED IN THE AFTERNOON = 310 + 200 = 510
CALORIES CONSUMED IN THE NIGHT = 800
Sum = 1620
he didn't reach is goal because he consumed only 1620 calories which is less than 2000

Find the perimeter of A ABC. If necessary, round to the nearest tenth.
Answer:
37.6
Step-by-step explanation:
A to B - just count up the numbers, it's 10
B to C - just count up the numbers, it's 12
A to C - Now this is a right triangle, so use the Pythagorean theorem(10^2 + 12^2 = 244, and take the square root of that, which is 15.62 and round to 15.6
And just add them together 10+12+15.6 to get 37.6

C. 50°, 50°, 50°
D. 60°, 60°, 60°
Answer:
D. 60, 60, 60
Step-by-step explanation:
In an equilateral triangle, all sides are equal and equal to 180 when added together. because 60×3 is equal to 180, D is the right answer. I hope this helps you!
The angle measurements found in an equilateral triangle are 60°, 60°, 60°
What is an Equilateral Triangle?An equilateral triangle is an angle that has equal angles and equal sides. It implies that all the sides of the angle contain the same length.
We can also say that an equilateral triangle is also equiangular since it has equal angles. If we recall, we know that the sum of angles in a triangle is 180°.
For a triangle with equal sides, it implies that each length will possess;
= 180°/3
= 60° each.
