For all of these we will use the Order of Operations, also known as PEMDAS, then compare the simplifed values to see if they are equal.
[a] Equivalent / Verified
(-5) * [(-7) + (-5)] = [(-5) * (-7)] + [(-5) * (-5)]
(-5) * [-12] = [35] + [25]
60 = 60
[b] Equivalent / Verified
(-7) * [(-8) + 9] = [-7 * (-8)] + [(-7) * 9]
(-7) * [1] = [56] + [-63]
-7 = -7
[c] Equivalent / Verified
(-25) * [(-7) + (-15)] = [(-25) * (-7)] + [(-25) * (-15)]
(-25) * [-22] = [175] + [375]
550 = 550
Answer:
96 m
Step-by-step explanation:
16m x 12m= 192
192/2=96
Step-by-step explanation:
lateral surface area here = πrl
r = 10
l = √h²+r²= √ 24²+ 10² = 26
lateral surface area = 10 × 26 × π

Distance hour hand travel in 5 hours is 20.94 inches.

What is a diameter?</h3>
- A diameter of a circle is any straight line segment that passes through the center of the circle and has endpoints on the circle in geometry.
- It is also known as the circle's longest chord.
- Both definitions apply to the diameter of a sphere.
To find the distance hour hand travel in 5 hours:
- Let's say the hour hand completed one full round around the clock.
- If this was the case, it would have been 2×8 inches around.
- We know that the hour hand only traveled 5 hours around the clock rather than 12, thus our formula is 2×8×( 5/12 ).
- Distance hour hand travel is 20.94 inches.
Therefore, the distance hour hand travel in 5 hours is 20.94 inches.
