A) 3x2=6+37=43
B) 43 rounding to greatest place value=40
Marco Weighs 40 Pounds.Its Because 3x4=6+37=43.Last When You Round 43 You Have To Round To The Greatest Place Value.So When You Round The 3 Is Low So You Change It To 0 And The 4 Stays The Same
Answer:
Surface Area = 6.28 x 5.223 x 3 + 6.28 x 10.446 = 164 cm^2
Step-by-step explanation:
A=2πrh+2πr2
When we divide 245 by 1.5 we find 164cm^2
Answer:
7 weeks
Step-by-step explanation:
John saves f(x) = 60+5x
Sarah saves g(x) =x^2 +46
They save the same amount of money
Set the equations equal
60+5x =x^2 +46
Subtract 60 from each side
60+5x -60 =x^2 +46-60
5x= x^2 - 14
Subtract 5x from each side
5x -5x= x^2-5x - 14
0 = x^2-5x - 14
Factor
0 = (x-7) (x+2)
Using the zero product property
x-7=0 x+2 =0
x=7 x=-2
Since we cannot have negative weeks
x=7
Answer:
<u>scalene</u>
Step-by-step explanation:
Length of XZ = √3² + 4² = √25 = 5
Length of ZY = √1² + 7² = √50 = 5√2
Length of XY = √4² + 5² = √41
As all lengths are different, the triangle is <u>scalene</u>
The given above is are triangles, as per the proof the line segments on top and bottom part are parallel. Also, it is given that two pairs of the angles of the triangles are congruent.
The triangles also share one common side, CA. Since, this side is between the angles the postulate that will prove the congruence of the triangles is ASA.
The answer to this item is the third choice.
