Answer:
$2250
Step-by-step explanation:
30 x 25 = 750 -> area
750 x 3= 2250
Answer:
y = -6
Step-by-step explanation:
-4-2y=-12
4+8y=-24
We can eliminate 4.
4+8y-4-2y = -12-24
Simplify.
6y = -36
Find y.
y = -36 ÷ 6
Simplify.
y = -6
Answer:
25.3°F
Explanation:
We need to find the difference between the temperature on August 27, 1975, and the average temperature. So, the difference is equal to:
107 °F - 81.7°F = 25.3°F
It means that on August 27, 1975, the temperature was 25.3°F hotter than average.
Answer:
a = 2 [m/s²]
Step-by-step explanation:
Here we need to think back to our good old friend Newton and his second law:
F = m·a
The first thing we are given is that when m = 22 [kg], a = 3 [m/s²]. With this, we can calculate F:
F = 22 · 3 = 66 [N]
Now that we have the force acting upon the two objects, we can calculate the second object's acceleration using this force:
F = m·a
⇒ a = F / m (divide both sides by m)
⇒ a = 66 / 33 = 2 [m/s²]
