Answer:
0.03
Step-by-step explanation:
Calculation for What number did Michael used
Using this formula
Number used=Number of Product recorded/Number multiplied
Let plug in the formula
Number used =0.012/0.4
Number used =0.03
CHECK: 0.4*0.03=0.012
Therefore the number that Michael used is 0.03
Let x represent the cost of book B
Book A: $17.50
Book B: x
Sales tax: (A + B) x 6% = .06(17.50 + x) = 1.05 + .06x
book A + book B + sales tax = total cost
(17.50) + (x) + (1.05 + .06x) = 44.52 <em>plugged in all of the values</em>
18.55 + 1.06x = 44.52 <em>added like terms</em>
1.06x = 25.97 <em>subtracted 18.55 from both sides</em>
x = 24.50 divided 1.06 from both sides
Answer: $24.50
Answer:
216 degrees
Step-by-step explanation:
Given that ABCDE is a regular pentagon.
Hence each angle would equal = {2(5)-4}/5 right angles
=6(90)/5 =108 degrees
Since regular pentagon rotation will not disturb the shape.
When counterclockwise rotated, if 108 degrees rotated A would become E.
For another 108 degrees A would come to D
Hence angle required for rotation for A to coincide with D = 2(108)
=216 degrees
Answer:
60
Step-by-step explanation:
The yellow and green angles form a right angle, so the measures of those combined will be 90 degrees.
90 - 30 = 60
