Answer:

B

Step-by-step explanation:

There isn't enough information because you never gave me the picture, but i think the triangle has sides 5 6 and 7 and is not a right triangle. You must apply the pythagorean thereom.

A bag of uninflated balloons contains 10 red, 12 blue, 15 yellow and 8 green balloons. A balloon is drawn at random, what is the
tia_tia [17]

We have been given that a bag of uninflated balloons contains 10 red, 12 blue, 15 yellow and 8 green balloons.

We need to find the probability of drawing a red balloon.

We know that probability is given by

\\
\text{Probability =} \frac{\text{Favorable outcomes}}{\text{Total outcomes}}

Since we know that there are 10 red balloons. Therefore, our number of favorable outcomes is 10.

In order to find the total number of outcomes, we will add balloons of all colors.

Therefore, total outcomes are  = 10+12+15+8 = 45

We can now substitute the values of favorable outcomes and total outcomes in order to find the required probability.

\\
\text{Probability =} \frac{\text{10}}{\text{45}} = \frac{2}{9}

Find the measures of the unknown angles in the triangle shown. Round it the nearest degree.
Fudgin [204]

Answer:

x = 49°

y = 41°

Step-by-step explanation:

Recall: SOH CAH TOA

✔️To find x, the trig function we would apply is Cos, which is:

Cos θ = Adjacent/Hypotenuse (CAH)

θ = x

Adjacent = 13

Hypotenuse = 20

Cos(x) = \frac{13}{20}

x = cos^{-1}(\frac{13}{20})

x = 49.4583981°

x = 49° (nearest degree)

✔️To find y, the trig function we would apply is Sin, which is:

Sin θ = Opposite/Hypotenuse (SOH)

θ = y

Opposite = 13

Hypotenuse = 20

Sin(y) = \frac{13}{20}

y = Sin^{-1}(\frac{13}{20})

y = 40.5416019°

y = 41° (nearest degree)

X = boys
y = girls

x + y = 40 (in a class there are 40 students)
x = y + 10 (t<span>here are 10 more boys than girls in the class</span>)

11. (-7,-12,0, 5,2,-4,-1) least to greatest ​
Mkey [24]

Answer:

-12, -7, -4, -1, 0, 2, 5

Step-by-step explanation:

The larger a negative number the less value it actually has, whereas the larger a positive number the more value it has. You can think about it as if someone has taken something from you. If I take $12 from you you have less money than if I were to only take $7 from you. With positive numbers, you would have more money if I gave you 5 dollars than if I only gave you 2 dollars. You will always have more money if I give you money than if I were to take away money, that is why positive numbers are greater than negative numbers.
