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
16893944 so uhmmm I guessed but I asked my friend and they said this
Answer:
Step-by-step explanation:The surface area of a sphere (the shape of a baseball) is given by the formula, SA = 4 (pi) r^2. Given the circumference of the circle, you can solve for the radius.
The formula for circumference is C = 2 x pi x r.
So input 9 for C and solve. 9 = 2 x pi x r.
You will get that r is equal to about 1.43 in.
Now put that r value into the surface area equation: SA = 4 (pi) 1.43^2
You will get a surface area equal to about 25.7 in^2.
Now multiply that number by the number of baseballs you need to cover, 100.
I'll let you do that step by yourself since it's simple algebra and you're smart enough to figure it out ;)
I believe x is 0 because if we assume y and x are 0 then 0=0 and 0= 5 x 0
Answer:
The number D = b2 – 4ac determined from the coefficients of the equation ax2 + bx + c = 0. The discriminant reveals what type of roots the equation has. Note: b2 – 4ac comes from the quadratic formula.
