Answer:
r = 3.
Step-by-step explanation:
16 = 10 + √(3r + 27)
√(3r + 27) = 6
Square both sides:
3r + 27 = 36
3r = 36 - 27 = 9
r = 3.
Check the result:
Left side of the equation = 16
Right side = 10 + √(9 + 27)
= 10 + √36 = 16
Answer:
The answer is: 3 feet.
Step-by-step explanation:
The area is found by multiplying the width times the length. For a square, the length = the width.
Multiply 3 * 3 to get 9. So each side is 3 feet.
Answer: C
Step-by-step explanation: For a function, each x-coordinate corresponds to exactly one y-coordinate.
To determine whether the graph shown here
is a function, we can use the vertical line test.
The vertical line test tells us that if each x-coordinate on the graph corresponds to exactly one y-coordinate, then any vertical line that we draw on the graph should hit the graph at only one point.
For the graph show here, any vertical line that you draw with hit the graph at only one point which means it does pass the vertical line test.
So this graph is a <em>function</em>.
Answer:
Amount of frozen soup = 2500 mL
Step-by-step explanation:
We are told that tom made 5,000 mL of soup.
We are also told he packed 2.5 Litres into his kids' lunches.
Now, from conversions,
1 liter = 1000 mL
Thus,
2.5 litres = 2.5 × 1000 = 2500 mL
Now, we are told he froze the rest of the soup.
Thus;
Amount of frozen soup = total amount of soup made - amount given to kids' lunch pack.
Amount of frozen soup =
5000 - 2500 = 2500 ml
