Answer:
1/4
Step-by-step explanation:
coins have 2 sides, tails and heads, so for it to land on tails is a 1/2 chance. Dice have 6 sides and 1,3,5 are all odd so its a 3/6 chance. Simplify 3/6 to 1/2 and multiply by 1/2 to get 1/4. im not sure, its my guess.
Answer:
A, C, E
Step-by-step explanation:
-4 + (4+5) = 5
A: (4 - 4) + 5 = 5, equivalent
B: (-4 - 4) + 5 = -3, not equivalent
C: -(4-4) + 5 = 5, equivalent
D: -(4) + (-4) + 5 = -3, not equivalent
E: -4 + 4 +5 = 5, equivalent
Answer:
x2-20x+100
Step-by-step explanation:
You have to factor the expression in order to get your answer
Do this by expanding out the expression: (x-10)(x-10) Then factor by multiplying each of the components! Use the FOIL acronym to help you. FOIL stands for First, Outer, Inner, Last. Meaning multiply the first numbers of the expressions together, then the outers, then the inner two numbers, then the last two numbers of the expression.
Multiply x and x to get , multiply x and -10 to get -10x, multiply -10 and x to get -10x, multiply -10 and -10 to get 100. Add them all together: . Then combine like terms
perimeter = 2W+2L
Length = 4W
160 = 2W +2(4W)
160 = 10W
w = 160/10 = 16 yards
length = 16*4 = 64 yards
Check:
64*2 = 128, 16*2 = 32
128+32 = 160
Length = 64 yards, Width = 16 yards
Answer:
L = 15, W = 8
Step-by-step explanation:
Perimeter = 2(L + W)
P = 40
L = 2W - 1
40 = 2((2W-1) + W)
40 = 4W - 2 + 2W
40 = 6W - 2
42 = 6W
W = 8
Since L = 2W - 1
L = 2(8) - 1
L = 15
