Answer:

Step-by-step explanation:

express b^-4 with a positive exponent using:



Change each of the fractions into decimals.
1/8 becomes 0.125
-1/7 becomes -0.143
and -0.02555
0.2
In order from least to greatest,
-0.143, -0.02555, 0.125, 0.2
OR
-1/7, -0.02555, 1/8 and 0.2
'is' in mathematics means equal
'of' in mathematics means multiplication
percent means over 100
84 = 74% * x
84 = 74/100 * x
84 = 37/50 * x
Multiply 50/37 on both sides, so we can isolate 'x'
85 * 50/37 = x
x = 4250/37
x ≈ 114.864865
84 is 74 percent of <span>114.86</span>.
Answer:
It is the third option: (10C1) (20C1( / 50C2.
Step-by-step explanation:
The number of ways of selecting 2 marbles = the number of combination of any 2 marbles in the 50 marbles in the bag and this is 50C2. It is combinations because the order of drawing the marbles does not matter.
The number of combinations of one being red and the other blue = 10C1 times 20C1.
So the answer is (10C1) (20C1( / 50C2.
