Answer:
12 cm²
Step-by-step explanation:
Length of rectangle = 5.6 cm
Width of rectangle = 2.1 cm
Area of rectangle = Length of rectangle×Width of rectangle
⇒Area of rectangle = 5.6×2.1
⇒Area of rectangle = 11.76 cm²
11.76 has 4 significant figures in order to write this term in 2 significant terms we round of the term
The last digit in the decimal place is 6. Now, 6≥5 so we round the next digit to 8 we get
11.8
Now the last digit in the decimal place is 8. Now, 8≥5 so we round the next digit to 2 we get
12
∴ Hence the area of the rectangle when rounded to 2 significant figures is 12 cm²
I would think this is many solutions, the reason is because, there is no specific answer (y) so, x could be anything because it would have to equal to y, which could also be anything! I hope im right! Sorry if im wrong!
In this question, it is given that An inverse trigonometric function is used to find the value of an unknown obtuse angle in a triangle. The inverse function returns the angle 68°.
Since the angle is obtuse angle, it means the measurement of the angle is greater then 90 degree. And to find the angle measurement, we have to subtract the given angle from 180 degree.
So the unknown angle is
And that's the required answer .

Answer:
c., d., f
Step-by-step explanation:
"elana walked 12 miles"
That is 12.
"then she walked 1/4 that distance"
That is 1/4 of 12 miles, so it is 1/4 * 12
She walked altogether
12 + 1/4 * 12 = 12 + 3 = 15
She walked altogether 15 miles.
a.12+1/4 = 12.25 which is not 15
b.12×1/4 = 3 which is not 15
c.12+1/4×12 = 12 + 3 = 15 which is correct
d.12(1+ 1/4) = 12(1.25) = 15 which is correct
e.12×3/4 = 9 which is not 15
f.12×5/4 = 15 which is correct
Answer: c., d., f
