Answer:
Second Option (10° Celsius)
Step-by-step explanation:
There is a formula to convert the temperature which is in degree Celsius into degree Fahrenheit and vice versa. The formula to convert the temperature in degree Fahrenheit into degree Celsius is:
C° = (F° - 32) * 5/9.
It is given that the temperature is 50° Fahrenheit. Therefore, F° = 50°. Substituting F° = 50° in the formula gives:
C° = (50° - 32) * 5/9.
Further simplification results in:
C° = 18 * 5/9. Therefore, C° = 10°.
So the correct answer is 10° Celsius!!!
Answer:
sin A = 15/17
sec A = 17/8
Step-by-step explanation:
15 cot A = 8
First get cot A alone.
cot A = 8 / 15
Since cot is the reciprocal of tan then flip 15 and 8.
tan A = 15 / 8
Now you have the opposite and adjacent sides, just find the hypotenuse with Pythagorean's theorem
15^2 + 8^2 = 289
= 17
Now that you have all the sides use the opposite and hypotenuse to get sine and the adjacent and hypotenuse to get cosine then flip to get secant.
sin A = 15/17
cos A = 8/17
sec A = 17/8
Answer:
3 more trucks
Step-by-step explanation:
7 cows a truck and 10 trucks equals 70 cows carried. 30 more cows/10 per truck equals 3 more trucks.
Answer:
B
Step-by-step explanation:
7m+11= -4 x 2m + (-4 x 3)
7m +11 = -8m -12
7m +8m = -12-11
15m = -23
Cross multiply the expression so that we can get
(1+sinx)(1-sinx) = cos^2 x
1 - sin^2 x = cos^2 x
cos^2 x + sin^2 x = 1
since
cos^2 x + sin^2 x = 1
therefore
1 = 1
the two expressions are identical in a trigonometric sense
