Answer:

\frac{\frac{1}{4}}{1}=\frac{\frac{5}{6}}{x}

Step-by-step explanation:

Per = 1

\frac{1}{4}

So, if we were to solve:

\frac{1}{4}=\frac{5}{6x}

\frac{1}{4}\cdot \:6x=1\cdot \:5

\frac{3}{2}x=5

\frac{3}{2}x\cdot \:2=5\cdot \:2

3x=10

\frac{3x}{3}=\frac{10}{3}

x=\frac{10}{3}

Troy can make \frac{10}{3} dozen of cupcakes.

Find the discount if a $69.99 item is on sale for $39.99.
inn [45]
The easiest way to do it (for me) is to find 1% of the regular price. I think we can round the prices to $70,00 and $40,00 to show nice percentage.

70 / 100 = 0,7

So 1% is 0,7. Now we can divide $40,00 by 0,7 to calculate how many percent it is:

40 / 0,7 = 57 (after rounding it to the nearest whole number)

So the discount was 100 - 57 = 43 percent.

Doublecheck (optional):

70 * 57% =
= 70 * 57/100 =
= 7 * 57/10 =
= 7 * 5 7,10 =
= 7 * 5,7 =
= 39,9 (the price after the discount)

70 * 43% =
= 70 * 43/100 =
= 7 * 43/10 =
= 7 * 4 3/10 =
= 7 * 4,3 =
= 30,1 (the value of the discount)

The difference of 0,1 is because of the rounding, but it's correct.

What is the GCF and LCM of -21 and 80? Please Help! Explanation Please! :) Will give brainliest! ASAP!
Lisa [10]

Answer:

GCF= 1

LCM= 1680

Step-by-step explanation:

GCF= Find the prime factorization of 21, 21 = 3 x 7

Find the prime factorization of 80, 80 = 2 x 2 x 2 x 2 x 5

Then multiply the prime factors both numbers have in common

LCM= multiply the two numbers together and ignore all negative signs

The angles of traingle are in the ratio 3:7:8 find them in degrees as well as in radians​
I am Lyosha [343]
30°, 70°, and 80°.
It is an acute-angled triangle.
Explanation:
The ratio of the measures of ∠s in Δ is 3:7:8.
So, let us suppose that the measures are, 3k, 7k, 8k.
Evidently, their sum is
180°.

3k+7k+8k=180
18k=180
k= 10

Hence, the measures are,
30°, 70°, and 80°.
As all the angles are acute, so is the triangle.
