What is ​ BC ​ ? <br><br> Enter your answer in the box.<br><br> units
Vladimir79 [104]

Answer:

BC = 25

Step-by-step explanation:

AB = AC since it is an isosceles triangle

4x+1 = 2x+23

subtract 2x from each side

4x-2x+1 = 2x-2x+23

2x +1 = 23

subtract 1 from each side

2x+1 -1 = 23-1

2x = 22

divide by 2

2x/2 =22/2

x =11

BC = 3x-8

BC = 3(11) -8

BC =33-8

BC = 25

Fernando is making 30 sundaes with mint, chocolate,and vanilla ice cream.1/3 of the Sunday's are mint ice-cream and 1/2 of the r
Alina [70]

Answer:

<u>10 sundaes</u> will be vanilla.

Step-by-step explanation:

Given:

Fernando is making 30 sundaes with mint, chocolate,and vanilla ice cream.

1/3 of the Sunday's are mint ice-cream.

And 1/2 of the remaining sundaes are chocolate.

The rest are vanilla.

Now, to find the number of sundaes that will be vanilla.

Fernando is making sundaes total = 30.

So, the quantity of sundaes that are mint ice-cream:

\frac{1}{3} \ of\ 30\\\\=\frac{1}{3} \times 30\\\\=10.

<em>Thus, 10 sundaes are mint ice-cream.</em>

So, the remaining sundaes are:

30-10=20.

<em>Thus, the remaining sundaes are = 20.</em>

Now, to get the quantity of chocolate sundaes of the remaining sundaes:

\frac{1}{2} \ of\ 20\\\\=\frac{1}{2} \times 20\\\\=10.

<em>Hence, 10 sundaes are chocolate of the remaining 20 sundaes.</em>

<em>As, given the rest are vanilla.</em>

Now, to get the vanilla sundaes we subtract the 10 chocolate ice-cream from the 20 remaining sundaes:

20-10=10.

Therefore, 10 sundaes will be vanilla.
