Answer:
StartFraction 16 over 81 EndFraction
Step-by-step explanation:
There are 4 prime numbers from 2 to 10 (2, 3, 5, 7) and 9 numbers from 2 - 10. Total possibilities: 9 * 9 = 81
Prime possibilities: 4 * 4 = 16
Therefore the answer is 16/81 or StartFraction 16 over 81 EndFraction
Answer:
Option C.300
Step-by-step explanation:
we know that
To find out how many times greater is the land area of the United States than that of Norway, divide the area of the United States by the area of the Norway
so

Remember that
To divide exponents (or powers) with the same base, subtract the exponents
so

Answer:
f ÷ 10
Step-by-step explanation:
We want to write an expression
divided by means the number or variable before comes first, then the divided by symbol, then what comes after
f ÷ 10
Answer:
(7, - 3 )
Step-by-step explanation:
Under a clockwise rotation about the origin of 270°
a point (x, y ) → (- y, x )
Thus
(- 3, - 7 ) → (7, - 3 )
Answer:
<u>The ordered pair of the solution is (0.022, -0.55). None of the alternatives given we can consider as the best estimate because there isn't at least one positive value for x, when it's actually positive. Picking (0, -2) as the best estimate is also far from the best estimate.</u>
Step-by-step explanation:
Let's solve the system of equations:
y = −25x
−2y = 5x+1
***********************
Substituting y in the 2nd equation:
-2 (-25x) = 5x + 1
50x = 5x + 1
45x = 1
x = 1/45
x = 0.022
**********************
Solving for y in the 1st equation:
y = -25 (0.022)
y = - 0.55
<u>The ordered pair of the solution is (0.022, -0.55). None of the alternatives given we can consider as the best estimate because there isn't at least one positive value for x, when it's actually positive. Picking (0, -2) as the best estimate is also far from the best estimate.</u>
