What is 2.161616 as a fraction?

1 answer:

8 0

repeating fraction, nice

2.16161616...=2+0.16161616...
solve the repeating part
let's say x=0.16161616
2 places repeat, multiply x by 10^2 or 100
100x=16.161616

now subtract x from taht
100x-x=16.161616-0.16161616
the repeats cancel and we get
99x=16
divide both sides b 99
x=16/99

so
16/99=0.16161616...

2+16/99 is the fraction
if ya wanted 1 fraction then
2+16/99=
198/99+16/99=
214/99

2.161616=214/99

Find the area of circle o if DCBO is a rectangle and DB measure 10 units

Dmitrij [34]

Answer:

$100\pi$

Step-by-step explanation:

Step 1: Identity the radius.

Since O is the center of the circle, and C and E lie on the circumference, OC and OE are the radii of the circle and thus,

OC=OE.

Step 2: Consider the rectangle.

All diagonals in a rectangle are congruent so this means

DB= OC ( OC is also a diagonal).

Thus, OC= 10 units.

Step 3: Analyze

So this means OE is also 10 units as well.

Since we know the length of the radius, Use the area of circle,

$\pi {r}^{2}$

$\pi( {10}^{2} ) = 100\pi$

So the area of a circle is 100 pi.

Ari thinks the perfect milkshake has 333 ounces of caramel for every 555 scoops of ice cream. Freeze Zone makes batches of milks

drek231 [11]

Answer:

Freeze Zone has too much caramel.

Step-by-step explanation:

Given:

Ari thinks the perfect milkshake has 333 ounces of caramel for every 555 scoops of ice cream.

Freeze Zone makes batches of milkshakes with 666 ounces of caramel and 888 scoops of ice cream.

Question asked:

What will Ari think about Freeze Zone's milkshakes ? ( option must be there)

Choose one answer:

Freeze Zone has too much caramel.

Freeze Zone has too little caramel.

Freeze Zone is just right.

Solution:

First of all we will find both person's ratio of caramel to ice cream in their milkshakes.

Ratio of Ari

$\frac{caramel}{milkshake} =\frac{333}{555} =\frac{3}{5}$

Ratio of Freeze Zone

$\frac{caramel}{milkshake} =\frac{666}{888} =\frac{3}{4}$

Now, to comparing ratio of Ari and ratio of Freeze Zone, we will equalize the denominator:-

For Ari:

Multiplying numerator and denominator by 4

$Ratio\ of\ Ari=\frac{3}{5}=\frac{3\times4}{5\times4} =\frac{12}{20}$

For Freeze Zone:

Multiplying numerator and denominator by 5

$Ratio\ of\ Freeze\ Zone=\frac{3}{4}=\frac{3\times5}{4\times5} =\frac{15}{20}$

By comparison, we find that for making 20 scoops of ice cream, Freeze Zone is using 15 ounces of caramel while Ari thinks that 12 ounces of caramel must be used to make perfect milkshakes.

Conclusion:

Freeze Zone has too much caramel.

Each course at Mt. Regis College is worth either 3 or 4 credits. The members of the men's swim team are taking a total of 48 cou

kolezko [41]

Answer:

3 Credit Courses = 37

4 Credit Courses = 11

Step-by-step explanation:

1. Set up 2 equations:

3x + 4y = 155

x + y = 48

2. Simplify the second expression for x by subtracting y from both sides

x = 48 - y

3. Substitute 48 - y for x

3(48-y) + 4y = 155

4. Simplify the expression by multiplying by 3

144 - 3y +4y = 155

5. Subtract 144 from both sides and subtract 3y from 4y

y = 11 = 4 Credit Courses

6. Substitute y for equation 2

x = 48-11

7. solve for x

x = 37 = 3 Credit Courses
