Answer:
i) 0.1056
ii) 0.105
iii) 0.1
iv) 0.1056
Step-by-step explanation:
0.36, to the power of 2 (0.36×0.36) is 0.1296
0.1296-0.03×0.8=0.1056
Answer:
432 yd squared
Step-by-step explanation:
This is a parallelogram. The area of a parallelogram is denoted by: A = bh, where b is the base and h is the height. Here, the base is b = 19 1/5 and the height is h = 22 1/2. Plug these in:
A = bh = (19 1/5) * (22 1/2)
To make this simpler, let's convert the numbers into decimals. 1/5 is just 0.2 so 19 1/5 is 19.2. 1/2 is just 0.5, so 22 1/2 is 22.5. Now we have:
A = 19.2 * 22.5 = 432
Thus the area is 432 yd squared.
Hope this helps!
Answer:
49°
Step-by-step explanation:
The given information that BC=DC tells you triangle BCD is an isosceles triangle and that angle y is one of the two equal base angles. Then ...
y + y + 82 = 180 . . . . . the sum of angle measures is 180 degrees
2y = 98 . . . . subtract 82
y = 49 . . . . . divide by 2
The measure of y is 49°.
<span>87 less than the quotient of an unknown number and 43 is -75
Converting that to mathematical equation:
87 - (x / 43) = -75
Evaluating the equation, we can the value of x.
87 - (x/43) = -75
-x/43 = -75 - 87
-x/43 = -162
-x = -6966
x = 6966</span>
