The formula of a circumference is:
r - radius
or
d - diameter
We have d = 12cm. Substitute:
One-fourth of the circumference:
Answer:
its b
Step-by-step explanation:
Rearrange the Pythagorean Theorem to find the missing side. The Pythagorean Theorem is:
c2=a2+b2
where c is the hypotenuse and a and b are the sides.
√(26^2- 24^2) = 10
no solution
subtract 7t from both sides
7t - 7t + 3 = 8 + 7t - 7t
3 = 8 is a false statement
Thus the equation has no solution
Answer:
Ok so we can see for every 2 cups of medium coffee, the balance goes down 5.30$. So that means that for every coffee, her balance goes down 2.65$. Solving for the x-intercept means how many medium coffees can I get until my balance is 0. First, we have to find the y-int so it's easy. The slope is -2.65 because for every medium coffee, her balance goes down 2.65$. So we have y=-2.65x+b. Plugging in any point, I choose (4,14.40), we get 14.4 = -2.65 × 4 +b. Solving for b we get 25 for the y intercept, meaning the equation is y = -2.65x + 25 . To find the x intercept, we set y=0. So we have 0 = -2.65x+25. Solving for x we get approx. 9.4. We can't have decimals so we round down to 9. So the x int is ≈ 9.4 meaning we can only buy 9 coffee and have a little extra. But, if the problem said how many more coffees can she get, then here is how we do it. Since she already got 4 coffees, and the max is 9, we do 9-4 and we get 5, so she can buy 5 coffeed more.

Answer:
The graph is drawn below.
Step-by-step explanation:
Let the minutes passed be and height of water level be cm.
Given:
Rate of rise of water level,
When
Therefore, the relationship can be expressed using the point-slope form of an equation if a line.
The point-slope form is given as:
Here,
Therefore, the relationship is given as:
Therefore, the relationship between the pool's water level (in centimeters) and time (in minutes) is.
The graph is shown below.
Answer: Points are (20, 220) and (15, 190)
