The answer is 49 because since she multiplied 5 by 7 you have to do the same to yellow marbles so 7×7 = 49
A. When you add to negative numbers, it is always negative. A positive + a positive is positive. In D, the answer is always 0. 1 + -1 is 0. In C, it varies. The bigger number not including the negative sign is the sign the number has. For example, -6 + 5 = -1. 6 is bigger than 5. You subtract the smaller number from the bigger number and that is the answer. You would then tack on the negative sign because it is -6, and 6 is bigger than 5.
Answer:
There are multiple ways to do so:
You can divide the number by 100 to convert it to a decimal
You could take your percentage and add a decimal two places to the left.
Examples of both:
For division its as simple as 75 divided by 100 = 0.75
If we are going to use the decimal method, lets say we have 45%, so we can do this:
45% =45.00
Move the decimal two places to the left.
0.45
The angle vertical to it is DF
Answer:
Step-by-step explanation:
By using the cos square identity in trigonometry i.e., cos2ϴ = 1 – sin2 ϴ, we can evaluate the exact value of cos(33 ). For calculating the exact value of cos(∏/6), we have to substitute the value of sin(30°) in the same formula.
cos(30°) = √1 – sin230°
The value of sin30° is 1/2 (Trigonometric Ratios)
cos(30°) = √1 – (1/2)2
cos(30°) = √1 – (1/4)
cos(30°) = √(1 * 4 – 1)/4
cos(30°) = √(4 – 1)/4
cos(30°) = √3/4
Therefore, cos(30°) = √3/2
