Vitek1552 [10]

Answer: 3668.94 m^2

Step-by-step explanation:

35.7 * 15.1 = 539.07

35.7 * 15.1 = 539.07

25.5 * 15.1 = 385.05

25.5 * 15.1 = 385.05

35.7 * 25.5 = 910.35

35.7 * 25.5 = 910.35

539.07 + 539.07  + 385.05  + 385.05   + 910.35  +  910.35  = 3668.94

Marco thinks the total number of runs a team scores in a season is a better indicator of how many wins it will have in that seas

This is a fair assumption, but not true in every instance. Since home runs do not indicate how many runs score, which are the decider in a win or a loss, they are less accurate at predicting.

Examine the quadratic equation 9x^2+12x +4= 0.
mestny [16]

Answer:

See answers and explanations

Step-by-step explanation:

A) Discriminant = b² - 4ac = (12)² - 4(9)(4) = 144 - 144 = 0

B) Since the discriminant is 0, this means the equation only has one root.

C) The root is real in this case since the discriminant is not negative. Otherwise, we would have two imaginary roots if it were (remember that complex roots come in pairs)

Find the surface area of the square pyramid 8mm 6mm
bija089 [108]

Answer:

136 mm²

Step-by-step explanation:

A=a^{2} +2a\sqrt{\frac{a^{2} }{4} } +h^{2}

A=6^{2} +2(6)\sqrt{\frac{6^{2} }{4} } +8^{2}

A=36 +12\sqrt{\frac{36 }{4} } +64

A=36 +12\sqrt{9 } +64

A=36 +12(3)+64

A=36 +36+64

A = 136
