Answer: D. The area is 50 square meters if the shaded area looks like .
Explanation:
assuming this is a rectangle, the larger region area is 15*5= 75 square meters.
The smaller region’s area would be 10*5= 50 square meters.
• remember that A=lw, where l is length and w is width.
Without an illustration & on the assumption this is a rectangular region, here are the conclusions:
• given these two areas,
If the shaded area looks like , the area is just 50 square meters because the dimensions needed to solve for the area were given.
OR
• If the shaded region looks like subtract the smaller area from the larger one: 75-50= 25 square meters. (However, given that this is not an answer choice, I don’t think the illustration would look like this).
Divisors of 18 are 1, 2, 3, 6, 9, 18.
Divisors of 24 are 1, 2, 3, 4, 6, 8, 12, 24.
The largest number on both lists is 6. This is the GCF of 18 and 24.
_____
a) No. The number present must be a divisor of 6.
b) Yes. The number present is a divisor of 6.
c) The number present must be a divisor of 6.
d) Possible numbers present are 1, 2, 3, 6.
Sin < C = 63/65 so m < C = 75.75 degrees
and tan B = 16/63 so m <B = 14.25 degrees
m < C + m<B = 75.75 + 14.25 = 90 degrees
Therefore m < A = 180-90 = 90
therefore the triangle is right-angled.
On your calculator, make sure you're in radian mode, not degree mode, that you are in a trig coordinate plane (do this by hitting "zoom" and choosing ZTrig), and when you enter the function into the "y =", you have to enter it in like this: 7cos(2x)-3. Hit "graph" and you'll see that the wave goes through the x-axis in 4 places within your specified interval. Hit 2nd and "trace" and then "zero". Move your cursor so it's just above the x-axis where the curve goes through and hit enter, then move it so it's just below the x-axis where the curve goes through and hit enter again. Hit enter a 3rd time, and you SHOULD see that your x has a value while y = 0. Do that for all of the places where the curve goes through the x-axis. That's how you find the zeros of a trig curve (or any curve, for that matter) on a calculator. The zeros are the solutions. If this was solvable like a regular equation, using trig identities and right triangles, you wouldn't have to use your calculator. But just like when you go to factor a second degree polynomial and you're having trouble with it you can use the quadratic formula and it's never-fail, neither is your calculator.
Answer:
The answer is 56.
Others are 50 + 57 = 107, 44 + 63 = 107, and 39,68
Step-by-step explanation:
107-51 = 56
