If the side lengths of a Triangle are: 2t, t, 3t, and the perimeter is equal to 60 meters; what is the value of t? a 20 b 12 c 10 d 6

Answers

Answer:

x equals 10

Step-by-step explanation:

so so you if the perimeter is 60 and when you measure perimeter you add up all these sides so you would add 2t + t + 3t = 60 then you would divide by 6 and get 10.

Two step equations x−17/3=−3

Answers

Answer:

[tex]\boxed {x = \frac{8}{3}}[/tex]

Step-by-step explanation:

Solve for the value of [tex]x[/tex]:

[tex]x - \frac{17}{3} = -3[/tex]

-Add both sides by [tex]\frac{17}{3}[/tex] and convert [tex]-3[/tex] to a fraction [tex]-\frac{9}{3}[/tex]:

[tex]x - \frac{17}{3} + \frac{17}{3} = -3 + \frac{17}{3}[/tex]

[tex]x = -\frac{9}{3} + \frac{17}{3}[/tex]

-Since both [tex]-\frac{9}{3}[/tex] and [tex]\frac{17}{3}[/tex] have the same denominator, then you would add the numerators:

[tex]x = \frac{-9 + 17}{3}[/tex]

[tex]\boxed {x = \frac{8}{3}}[/tex]

Therefore, the value of [tex]x[/tex] is [tex]\frac{8}{3}[/tex].

Use the Pythagorean Theorem to find the missing length. Round your answer to the
nearest tenth.

Answers

In this triangle it is clear that the unknown side x is the hypotenuse of both the triangles that are being formed . So , let us take any one of the triangles and with it's length let us find the length of their hypotenuse which is side x .

= 5² + 5² = x² ( according to the pythagorean theorem the square on the hypotenuse will be equal to the sum of the squares on the other two legs )

= 25 + 25 = x²

= 50 = x²

= 7.0710678119 = x

But they have given that we have to round it off to the nearest tenths , so ;

= 7.0710678119 will be equal to = 7.10

= 7.1 = x

Therefore , the length of the unknown side x = 7.1 .

Answer:

6^10

Step-by-step explanation:

6^0 is essentially just 1. So 6^10 x 1 is 6^10.

Answer:

6^10

Step-by-step explanation:

When multiplying exponents with the same base number, you simply add the exponents and keep the bases the same

a^m * a^n = a^m+n

6^10 * 6^0 = 6^10+0

You can also look at it this way:

Any non-zero number to the power of 0 will ALWAYS equal 1

a^0=1

6^10 * 6^0 = 6^10 * 1 = 6^10

You spend 30 minutes watching television . You then spend 2 hours playing video games . Write the ratio of the amount of time spent to the amount of time spent as a fraction in simplest form.


The ratio in simplest form is ???

Answers

Answer:

television/ video games= 1/4

Step-by-step explanation:

cuz there are 2 sets of 30 min in an hour, make the video games time 4 sets of 30 min, and the tv time 1 set. so , the ratio would be 1/4.

The ratio of the amount of time spent on watching television to the amount of time spent on playing video games as a fraction in the simplest form is 1 : 4.

What is ratio?

Ratio basically compares quantities, that means it shows the value of one quantity with respect to the other quantity.

If a and b are two values, their ratio will be a:b,

Given that,

Time spend on watching television = 30 minutes.

And time spend on playing video games = 2 hours.

To find the ratio of the amount of time spent on watching television to the amount of time spent on playing video games,

Use ration property,

Ratio = time spend on watching television/ time spend on playing video games

         = 30 minutes / 2 hours

         = 30 minutes / 2 x 60 minutes

         = 1 / 4

Ratio = 1 : 4

The required ratio of time spend on television to time spend on playing video games is 1 : 4.

Write an equation of the line that passes through (2,−5) and is parallel to the line 2y=3x+10

Answers

Step-by-step explanation:

Divide two on both sides to get rid of it and the make the equation in the form y = mx + c

[tex] \frac{2}{2} y = \frac{3}{2} x + \frac{10}{2} [/tex]

y = 3/2x + 5

since both lines are parallel they must have the same gradient which is 3/2

y = 3/2x + c

All you have to do now is to replace x and y with (2, -5) to find c

x = 2

y = -5

-5 = 3/2 × 2 + c

-5 = 3 + c

c = -5-3

c = -8

[tex]y = \frac{3}{2} x - 8[/tex]
