Answer:
14
Step-by-step explanation:
There are 3 even and 3 odd sides meaning its a 50/50 chance for either to happen each time you roll. This means half of the results are expected to be odd and even.
Answer:
B.
Step-by-step explanation:
Volume of the model of moon = 4/3(πr³)
= 4/3(π)(1)³
= 4.2 feet³
Volume of cylinder = πr²h
= (3.14)(0.5)²(0.5)
= 0.39 feet³
Cylindrical clay boxes to be used = 4.2/0.39
=10.7 ≈ 11
Answer:
Negative
Step-by-step explanation:
(-2)^4 will be positive because the exponent is even.
(-3)^7 will be negative because the exponent is odd.
An positive number times a negative number is negative, so we know the result will be negative.

Answer:
169/4
Step-by-step explanation:
Take the coefficient of the x term. Here it's -13. Now halve that, obtaining -13/2. Finally, square this result. We get 169/4. This is the desired number.
x^2 - 13x + 169/4 - 169/4 + 14 = 0
Answer:
Step-by-step explanation:
vertices are A(-3,3),B(-2,4),C(4,0)
slope of AB=(4-3)/(-2+3)=1/1=1
slope of BC=(0-4)/(4+2)=-4/6=-2/3
slope of CA=(3-0)/(-3-4)=-3/7
two lines are perpendicular if product of slopes=-1
so it is not a right angled triangle .
