The school is having a bake sale and the math club is bringing cupcakes. They have 180 total cupcakes, both chocolate and strawb

jeka57 [31]

Let $s$ be the number of strawberry cupcakes, and $c$ the number of chocolate cupcakes.
From our problem we know that the total number of cupcakes is 180, so $c+s=180$ . We also know that the number of chocolate cupcakes is eighteen more than twice the number of strawberry cupcakes, so $c-18=2s$ , or solving for $c$ : $c=2s+18$ .
Know we have our system of equations:
$\left \{ {{c+s=180} \atop {c=2s+18}} \right.$
We can conclude that the correct answer is B. c + s = 180 c = 2s + 18.

Lets solve our equations to find how many cupcakes of each they have:
from our second equation we know that $c=2s+18$ ; lets replace that value in our first equation to find the number of strawberry cupcakes:
$2s+18+2=180$
$3s=162$
$s= \frac{162}{3}$
$s=54$
Now that we know the number of strawberry cupcakes, lets replace that value in our second equation to find the number of chocolate cupcakes:
 $c=2(54)+18$
$c=108+18$
$c=126$
As a bonus, we can conclude that the math club have 126 chocolate cupcakes and 54 strawberry cupcakes.

Describe how you would estimate the square root of a number that is not a perfect square without using a calculator.

docker41 [41]

The square root must be between the square roots of the perfect squares just above and just below your number.

For example the square root of 89 must be between 9 and 10.

An angle measures 38° less than the measure of its complementary angle. What is the measure of each angle?

xxMikexx [17]

Answer:

One angle is 26 degrees and the other is 64 degrees.

Step-by-step explanation:

Complementary angles add up to a total of 90 degrees. Therefore, if one of the two angles is known to be 38 degrees less, then the other angle can be calculated:

90 = (x-38) + (x)

52 = 2x

26 = x

This means that one of the angles is 26 degrees, and the other is 64 degrees.

Find the probability of getting a 1, 4, or 5 when you roll a standard six-sided die. Give your answer as a simplified fraction.

aivan3 [116]

The first thing to take into account is that the probability of getting any of the six numbers of the dice after rolling it is the same and that probability is 1/6. Here we are being asked about the probability of getting a 1 or a 4 or a 5. In order to find it we need to define which are our favourable cases. Favourable cases are the results we want to get when we roll the dice so getting a 1, a 4 or a 5 are all favourable cases. All the other possible outcomes are unfovourable cases: getting a 2, a 3 or a 6. So we have 3 favourable and 3 unfavourable cases. Adding them we know that the total amount of cases is 6. The probability we are looking for (i'm going to call it P) is given by these quantities I defined:

$P=\frac{\text{ favourable cases}}{\text{total amount of cases}}=\frac{3}{6}=\frac{1}{2}$

So the probability written as a simplified fraction is 1/2.
