Answer:
Step-by-step explanation:
16 divided by $3.50 = 4.5
152.4cm. 2.54cm = 1in. 60in x (2.54cm/1in) = 152.4cm.
Answer:
Um.. well I don't know what is your question, but I think you meant square root and the answer is 7 because it is a perfect square.
Step-by-step explanation:
The probability of landing on a shaded sector is 2/5.
(a) 95 = (x+7)*(x-7)
(b) 95 = (x+7)*(x-7)
Expand the brackets:
95 = x² -7x + 7x -49 = x² - 49
Subtract x² from both sides:
95-x² = -49
Subtract 95 from both sides:
-x²=-49-95
-x²= -144
Divide both sides by -1 to get rid of the negative numbers:
-x²/-1=-144/-1
x²=144
Take the square root of 144:
x = ± squareroot of 144
x = 12 or -12
x = 12 because you cannot have a negative age so Trina is 12 years old.
