Thats easy for example the first question 3.2*2.8*6.1=?
first multiply 3.2*2.8 which equals 8.96 then multiply that number times 6.1 so like this-> 8.96*6.1 which your answer is 54.656.
So answers for numbers 1-3 are
1) 54.656
2) 90
3) 15.603
enjoy!
ANSWER: 1 SOLUTION
Step 1: Subtract 2x-1 from both sides.
x2−(2x−1)=2x−1−(2x−1)
x2−2x+1=0
Step 2: Factor left side of equation.
(x−1)(x−1)=0
Step 3: Set factors equal to 0.
x−1=0 or x−1=0
x=1
Answer:
x=1
Volume of a cilinger, V = π(r^2)H
Here, V = 540π ft^3 and H =15 ft
Then, r^2 = 540π ft^3 / [π15ft] = 36ft^2
r = √(36ft^2) = 6ft
And the diameter is 2*r = 12 ft
Answer:
COB and AOD
Step-by-step explanation:
Reminder: vertical angles are pairs of opposite angles that is made from intersecting 2 line/line segment.
In this case, to find pairs of opposite angles, you would look at angles that share a center but do not share a line segment.
If you check all of these, it's clear that COB and AOD is the only valid answer.
