Find the value of y.<br> y = 5<br> y = 10<br> y = 47.5<br> y = 60
Citrus2011 [14]

Answer:

y = 5

Step-by-step explanation:

All the sides are equal, so all the angles are equal

The angles of a triangle add to 180

180/3 = 60

Each angle is 60 degrees

8y+20 = 60

Subtract 20 from each side

8y+20-20 = 60-20

8y= 40

Divide by 8

8y/8 = 40/8

y = 5

Work out the value of the first negative term of the sequence 25 - 3n
fiasKO [112]

Answer:

-2.

Step-by-step explanation:

3n must be greater than 25 for the first negative term:

3n > 25

n > 25/3

n > 8 1/3.

So n = 9 and the first negative term is 25 - 3*9

= 25 - 27

= -2.

Isabella has a 22 ounce cola. She drinks 17 ounces. Enter the percentage of ounces Isabella has left of her cola. Round your ans
jenyasd209 [6]

Answer:

<u>22.73%</u> of ounces Isabella has left of her cola.

Step-by-step explanation:

Given:

Isabella has a 22 ounce cola. She drinks 17 ounces.

Now, to find the percentage of ounces Isabella has left of her cola.

Total ounces of cola = 22.

Ounces of cola Isabella drink = 17.

So, the ounces of cola she left:

<em>Total ounces of cola - ounces of cola Isabella drink.</em>

=22-17

=5\ ounces.

<u><em>Thus, 5 ounces of cola she left.</em></u>

Now, to get the percentage of cola she left:

\frac{5}{22}\times 100

=\frac{500}{22}

=22.727\%.

<u>Rounding the percentage to the nearest hundredths is 22.73%.</u>

Therefore, 22.73% of ounces Isabella has left of her cola.
