A triangle with sides lengths of 5 and 8 solve for x

Elina [12.6K]

The lengths of two sides is not enough information to determine a unique triangle. There are an infinite number of possible correct answers. If 'x' is the length of the third side, then its length can be anything between 3 and 13.

S+2t=6. 3s-2t=2 Using elimination

Ludmilka [50]

For the first one, I will solve for t.
s + 2t = 6, first we isolate the t variable,
2t = -s + 6, divide both sides by 2,
t = -s/2 + 3, < There's your answer for 1!

Here's the second one,
3s - 2t = 2, subtract 3s from both sides,
-2t = 2 - 3s, divide both sides by -2,
t = -1 + 3s/2 < There's your second answer!

A researcher wants to know how professional athletes in her city feel about safety measures. She obtains a list of 952 professio

mojhsa [17]

Answer:

For this case the population represent all the professional athletes in the researcher city and we can assume that the sample size for tis population is N =982 and represent all the individuals of interest for the study and the parameter of interest is the proportion of athletes who believe that the enforcement of safety measures needs to be completely overhauled $p$ .

In order to estimate te parameters of the population the researcher select a sample of 400 professional athletes and just 86 of them returns the questionnaire sent. So then the real sample is the n =86 people who return the info, because the other people are part of the non response rate, and from this sample she found that the proportion of athletes who believe that the enforcement of safety measures needs to be completely overhauled is $\hat p=0.76$ .

The graph shows the distance, y, in miles, of a moving motorboat from an island for a certain amount of time, x, in hours:

lisabon 2012 [21]

Answer: The speed of the motorboat is 70 miles per hour

Step-by-step explanation: Subtract the initial distance, 35, from the distance at any given time, then divide the remainder by the hours.

For example, at 2 hours, the distance shown on the graph is 175 miles

Subtract: 175 -35 = 140. Then divide 140/2 = 70

At 4 hours, the distance shown is 315 miles.

Subtract: 315 - 35 = 280. Then divide 280/4 = 70

70 mph is the speed.

Draw a right triangle with side lengths of 3, 4, and 5 units. and answer the problem please :')

11111nata11111 [884]

Answer:

Image below

Step-by-step explanation:

Given: Side lengths of a right triangle 3,4 and 5 units.

To draw: A right triangle with the given side length.

Solution:

We know, in a right angle triangle hypotenuse is the longest side and satisfying Pythagoras theorem.

From the given side length,

Hypotenuse = 5 unit

We can take any of the base and perpendicular.

Let, Base = 3 unit

Perpendicular = 4 unit.

It a right-angle triangle with a hypotenuse 5 unit.

Now we draw a right angle triangle taking in the first 3 base and 4 perpendicular and second 3 perpendicular and 4 bases.
