For this case we must write as a percentage the following expression:
Dividing we have to:
Now we multiply by 100%. So:
We run the decimal two spaces to the right, finally we have:
84%
Answer:
84%
Answer:
Part 1) The exact value of the arc length is \frac{25}{6}\pi \ in
Part 2) The approximate value of the arc length is 13.1\ in
Step-by-step explanation:
ind the circumference of the circle
The circumference of a circle is equal to
C=2\pi r
we have
r=5\ in
substitute
C=2\pi (5)
C=10\pi\ in
step 2
Find the exact value of the arc length by a central angle of 150 degrees
Remember that the circumference of a circle subtends a central angle of 360 degrees
by proportion
\frac{10\pi}{360} =\frac{x}{150}\\ \\x=10\pi *150/360\\ \\x=\frac{25}{6}\pi \ in
Find the approximate value of the arc length
To find the approximate value, assume
\pi =3.14
substitute
\frac{25}{6}(3.14)=13.1\ in
Answer:
D
Step-by-step explanation:
(-18) + 6/(-18) - 3
-12/-21
simplify it down
-4/-7
2 negatives make a positive
so 4/7
so x = -18
Answer:
Correct choice is B
Step-by-step explanation:
Unknown leg x in right triangle is opposite to the angle of the measure of 50°. Use the definition of the sine of the angle:
Hence,
Answer:
18 milky ways = 60%
3 twix = 10%
9 snickers = 30%
Step-by-step explanation:
18/30 = 0.6
0.6 x 100 = 60%
3/30 = 0.1
0.1 x 100 = 10%
9/30 = 0.3
0.3 x 100 = 30%
