Answer:
yes; x=7
Step-by-step explanation:
When two corresponding angles are congruent, all angles are congruent, so the triangles are similar. The sides of the triangle on the right are 30/25 = 6/5 times the length of the sides of the left triangle, so side MP will be 6/5 times the length of JL, or (6/5)·20 = 24.
Then the expression for that length lets us find the value of x:
24 = 4x -4
6 = x -1 . . . . . divide by 4
7 = x . . . . . . . add 1
Are you solving for x or y
y= 24x x= y/24
X=5
each side of the small triangle is multiplied by 5 to make the larger triangle and 4x5 is 20. So 20-8=12. And 3x4 is 12.
Answer:
About 68% will make between $200000 and $240000.
Step-by-step explanation:
C. About 68% will make between $200000 and $240000. If the standard deviation is $18,000, then add that to $225000. That equals $243000. Subtract $18000 from the average, you end up with $207000. So it is close, but about 68% will make between $200000 and $240000.
