Given a right triangle, find the length of the missing leg given the hypotenuse is 13 cm and the other leg is 5 cm. (Round to two decimal places.)

Answers

Answer:
The length of the missing leg is 12 cm.

Explanation:

a² + b² = c² (Pythagoras theorem)

c is the hypotenuse (longest length) of a triangle.

a and b are the two other side of the triangle excluding the longest one.


Let x cm be the length of the missing leg of the right triangle.

x² + 5² = 13² (Pyth. Thm.)

x² = 13² - 5²

x² = 169 - 25

x² = 144

x = √144

x = 12

Hope it helps! Mark me brainliest if it’s correct.

The length of the missing leg given the hypotenuse is 13 cm and the other leg is 5 cm would be 12 cm.

What is the Pythagoras theorem?

The Pythagoras theorem states that the square of the longest side must be equal to the sum of the square of the other two sides in a right-angle triangle.

a² + b² = c² (Pythagoras theorem)

where, c is the hypotenuse (longest length) of a triangle.

And a and b are the two other side of the triangle excluding the longest one.

Let x be the length of the missing leg of the given right triangle.

x² + 5² = 13²

x² = 13² - 5²

x² = 169 - 25

x² = 144

x = √144

x = 12

Hence,  the length of the missing leg given the hypotenuse is 13 cm and the other leg is 5 cm would be 12 cm.

Lisa and Marie are both on the track team. During practice, Lisa ran 10 laps around
the track in 18 minutes. Marie ran 8 laps around the track in 14 minutes. Who ran at a
faster rate? If each runner continues at her same pace, how long would it take each
one to run 15 laps?

Answers

Answer:

Marie ran at a faster rate. It takes 27 minutes for Lisa to run 15 laps while it takes Marie 26.25 minutes to run 15 laps.

Step-by-step explanation:

18 ÷ 10 = 1.8 (Lisa's rate)

14 ÷ 8 = 1.75 (Marie's rate)

1.8 x 15 = 27 minutes (How long it takes for Lisa to run 15 laps)

1.75 x 15 = 26.25 (How long it takes for Marie to run 15 laps)

In an isosceles triangle the base angles are both 32 degrees, find the vertex

Answers

Answer:

116 deg

Step-by-step explanation:

note that an isoceles triangle always have 2 base angles that are equal.

Here we are already given one base angle of 32 deg. It follows that the other base angle must also be 32 deg.

We now have 2 angles of a triangle and we need to find the remaining one. Also recall that all 3 internal angles of a triangle sum to 180 deg. if we let the missing angle be x, then:

base angle + base angle + vertex angle = 180°

or,

32° + 32° + x° = 180°

64° + x = 180 deg

x = 180 - 64

x = 116 deg

if Richard worked for 7 dollars and made 9 dollars and hour how much would he make?

Answers

Answer:

$63

Step-by-step explanation:

I believe you meant Richard worked for 7 hours and made $9 per hour.

In order to know how much Richard earned for 7 hours, you have to multiply Richard's salary rate with his number of working hours.

7 hours x 9 dollars/hour = $63

Therefore, Richard earned $63 for his 7-hour work.

Additional Information

Another example is: if Richard worked for 10 hours, you just have to multiply his salary rate again to his number of working hours.

10 hours x 9 dollars/hour = $90

The value of a collectible toy is increasing exponentially. The two points on the graph
show the toy's initial value and its value 3 weeks afterward.

Answers

The question is incomplete. Here is the complete question.

Part A

The value of a collectible toy is increasing exponentially. The two points on the graph show the toy's initial value and its value 3 weeks afterward.

Express the toy's value t, in dollars, as a function of time w in weeks after purchase.

Part B

Write an expression to represent the toy's value 10 days after purchase

Answer and Step-by-step explanation: An exponential function is of the form: [tex]y=ab^{x}[/tex]

Part A

Translating to the question, the toy's value as a function of time is

[tex]t=ab^{w}[/tex]

To determine constants a and b, we use points given by graph.

First, (0,5) to find a:

[tex]5=a.b^{0}[/tex]

a = 5

Now, (3,10) to determine b:

[tex]10=5b^{3}[/tex]

[tex]b=\sqrt[3]{2}[/tex]

b = 1.26

The toy's value as a function of time in weeks is [tex]t=5.(1.26)^{w}[/tex]

Part B

Since, the function is in weeks:

1 week = 7 days

w weeks = 10 days

[tex]w = \frac{10}{7}[/tex]

Replacing w:

[tex]t=5.(1.26)^{w}[/tex]

[tex]t=5.(1.26)^{10/7}[/tex]

Expression that represents toy's value after 10 days is [tex]t=5.(1.26)^{10/7}[/tex].
