For this question, we use the Pythagorean theorem.

a^2+b^2=c^2

We know the lengths of the legs, a and b.
a=3
b=4

Now, let's solve for the hypotenuse, c.

3^2+4^2=c^2
25=c^2

Take the positive square root.

\boxed{c=5}

Hope this helps! :)

lubasha [3.4K]
We have to convert the distance of 0.25 kilometers into feet. First, we convert 0.25 kilometers into meters. Since 1 kilometer has 1000 meters, we multiply 0.25 km by 1000 m/km to get 250 m. Next, 1 foot has 0.3048 m, so we divide the 250 meters by 0.3048 m/ft to get the number of feet, which is 820.21 ft.

#7. Suppose the amount of a popular sport drink in bottles leaving the filling machine has anormal distribution with mean 100,5
Scilla [17]

Apply z-score

Given data

\begin{gathered} \operatorname{mean}\text{ }\mu\text{ = 100.5} \\ \text{Standard deviation }\sigma\text{ = 1.5} \\ x\text{ = 102.1} \end{gathered}

Here, we use the normal distribution formula below to calculate the answer.

\begin{gathered} z\text{ = }\frac{x\text{ - }\mu}{\sigma} \\ \text{Next, substitute the values of }\sigma,\text{ }\mu\text{ and x.} \end{gathered}\begin{gathered} z\text{ = }\frac{102.1\text{ - 100.5}}{1.5} \\ z\text{ = }\frac{1.6}{1.5} \\ z\text{ = 1.067} \end{gathered}

Next, use the normal distribution table to find probability.

From the normal distribution table,

The probability that the mean content is less than 102.1 mL = 0.3554

Final answer = 0.3554

Complete Question

The lions and the tigers played a football game. The Lions scored three more than three times the number of points the Tigers scored. The total number of points scored by both teams is 31. How many points were scored by each team?

Answer:

The number of points scored by the Lions = 24

The number of points scored by the Tigers = 7

Step-by-step explanation:

Let the number of points scored by the lion = l

The number of points scored by the tiger = t

The Lions scored three more than three times the number of points the Tigers scored.

l = 3 + 3(t)

The total number of points scored by both teams is 31.

= l + t = 31

3 + 3t + t = 31

4t = 31 - 3

4t = 28

t = 28/4

t = 7 points

Note:

l + t = 31

I = 31 - t

l = 31 - 7

l = 24 points

The number of points scored by the Lions = 24

The number of points scored by the Tigers = 7
