Answer:
1,200
Step-by-step explanation:
To do this problem you do ten to the 2nd power which is 100 then you multiply 100 by 1.2 which is 120, which is then multiplied by 10 to get 1,200
Answer:
see below
Step-by-step explanation:
The perimeter is the sum of all the sides
A + B+ C+ D + E = 190
x+5 + x+10 + -5(x-20) + 6x-10+ 2x+4(20-x) = 190
Distribute
x+5 + x+10 -5x+100 +6x-10 +2x +80 -4x = 190
Combine like terms
x + x -5x-4x+6x +2x +80+10+100 -10+5 = 190
x +185 = 190
Subtract 185 from each side
x+185-185 = 190-185
x = 5
Side A = x+5 =5+5 =10
Side B = x+10 = 5+10 =15
Side C = -5(x-20) = -5(5-20) = -5(-15) = 75
Side D = 6x-10 = 6(5) -10 =30-10 = 20
Side E = 2x+4(20-x) = 2*5 +4(20-5) = 10+4(15) = 70
Answer:
dale is not correct
the correct angle is 30 degrees
Step-by-step explanation:
A cake is shaped like a circle
the total sum of angles in a circle is 360 degrees
If Dale and 2 friends share one fourth of a cake, the total angles they share = (1/4) X 360 = 90 degrees
If the 3 friends share the cake equally, the angles each get = (1/3) x 90 = 30 degrees
the correct angle is 30 degrees and not 45 degrees. Thus, Dale is wrong
Answer:4/12 3/6 4/6 13/7 22/11
Step-by-step explanation: 4/12=1/3; 3/6=1/2; 4/6 it's near 3/6; 13/7 is near 14/7=2; 22/11=2.
