Answer:
11 times
Step-by-step explanation:
Sample space = {red, green, blue, yellow)
Probability of landing blue in a single spin ;
P(blue) = required outcome / Total possible outcomes
P(blue) = number of blue / sample space
P(blue) = 1/4
Number of spins = 43
Expected number of times it'll land on blue :
P(blue) * number of spins
1/4 * 43 = 10.75
About 11 times
Answer:
27.27cm²
Step-by-step explanation:
∅=125° r=5m
A=∅/360×πr²
A=125/360×3.142×5²
A=27.27cm²
For this case we have that by definition of multiplication of powers of the same base, the same base is placed and the exponents are added:
So, we can rewrite the given expression as:
So, if

Answer:
Answer:
jim is correct, x <em>does</em> equal 7°. justify your answer by putting seven back into the equation. it gives you back that 180 equals 180, therefore it is correct
Step-by-step explanation:
so, all angles of a triangle have to add up to 180;
(15x) + (8x - 11) + (3x + 9) = 180
15x + 8x - 11 + 3x + 9 = 180
add your common numbers
26x - 2 = 180
add 2
26x = 182
divide 26
x = 7
put it back into the equation
15(7) + 8(7) - 11 + 3(7) + 9 = 180
180 = 180
