What is the length of the missing side of this right triangle? WILL GIVE BRAINLIEST

Answers

Answer:

I think its about 9? being as if you look a it its close to 12 but nowhere near it.

It is 9, because of Pythagorean’s theorem (assuming it is a right triangle) a^2+b^2=c^2, a and b are the legs and c is the longest part, the hypotenuse, plus 12 in for b and 15 in for c.
a^2+12^2=15^2
a^2+144=225
a^2=81
sqrt(a^2)=sqrt(81)
a=9

A 0.450 L sample of nitrogen gas is collected under a pressure of 2.30 atm and a temperature of 60.0 degrees Celsius. The sample is transferred to a 0.600 L container and the pressure drops to 1.54 atm. What is the new temperature of this gas (in K)?

Answers

Answer:

326.56K

Step-by-step explanation:

Step one:

Given

V1=0.45L

P1=2.3atm

T1=60 °

V2=0.6L

P2=1.54atm

T2=?

Step two:

Required:

T2

Applying the partial gas formula

[tex]\frac{P1V1}{T1}=\frac{P2V2}{T2}[/tex]

[tex]\frac{2.3*0.45}{60}=\frac{1.54*0.6}{T2}[/tex]

cross multiply we have

T2=(1.54*0.6*60)/2.3*0.45

T2=55.44/1.035

T2=53.56 °

in kelvin, we need to add 273

=273+53.56=326.56K

T2=326.56K

The new temperature of this gas (in K) is 326.56K

Marisol is given the following three lengths of a possible triangle: 1, 2 and 7. Would these side lengths form a triangle?

Yes, because 1 + 2 > 7, 2 + 7 > 1 and 7 + 1 > 2.

Yes, because 1 + 2 1 and 7 + 1 is greater than 2.

No, because 1 + 2 < 7 and in order for side lengths to meet the Triangle Inequality Theorem, any two side lengths must be greater than the third side when added together.

Answers

Answer:

no because 1+2<7. To form a triangle any two lengths have to be greater than third one

To create a trinomial square on the left side of the equation, find a value that is equal to the square of half of  b .

( b 2 ) 2 = ( 8 ) 2

Add the term to each side of the equation.

x 2 + 16 x + ( 8 ) 2 = 3 + ( 8 ) 2

Simplify the equation.

Raise  

8

to the power of  2 .

x 2 + 16 x + 64 = 3 + ( 8 ) 2

Simplify  3 + ( 8 ) 2 .

Tap for more steps...

x 2 + 16 x + 64 = 67

Factor the perfect trinomial square into  ( x + 8 ) 2 .

( x+ 8 ) 2 = 67

Solve the equation for  x .

Tap for fewer steps...

Take the square root of each side of the equation to set up the solution for  x .

( x + 8 ) 2 ⋅ 1 2 = ± √ 67

Remove the perfect root factor  

x + 8

under the radical to solve for  x .

x + 8 = ± √ 67

Remove parentheses.

x + 8 = ± √ 67

Subtract  

8

from both sides of the equation.

x = ± √ 67 − 8

The result can be shown in multiple forms.

Exact Form:

x = ± √67 − 8 x 2 + 16 x = 3

Change 5x+1=4y+7 to slope intercept form ( y=mx+b)

Answers

Answer:

Step-by-step explanation:

5x + 1 = 4y + 7

5x - 4y = 7 - 1

-4y = -5x + 6

-4y/-4 = -5x/-4 + 6/-4

y = 5/4x - 6/4

y = 5/4x - 3/2

Answer:

Work shown below!

Step-by-step explanation:

5x + 1 = 4y + 7 to y = mx + b

5x + 1 = 4y + 7

Subtract 7 from both sides;

5x - 6 = 4y OR 4y = 5x - 6

4y = 5x - 6

Divide both sides by 4;

The school that Eduardo goes to is selling tickets to a fall musical. On the first day of ticket salesthe school sold 3 adult tickets and 7 student tickets for a total of $81. The school took in $94 onthe second day by selling 4 adult tickets and 7 student tickets. Find the price of an adult ticketand the price of a student ticket.A) adult ticket: $6, student ticket: $13B) adult ticket: $13, student ticket: $6C) adult ticket: $17, student ticket: $9D) adult ticket: $19, student ticket: $8

Answers

Answer: B) adult ticket: $13, student ticket: $6

Step-by-step explanation:

Let adults tickets be written as a

Let student tickets be written as s

We then use the information given in the question to form equation. This will be:

3a + 7s = 81 .......... equation i

4a + 7s = 94 .......... equation ii

Subtract equation i from ii

a = 13

Adult tickets cost $13

From equation i

3a + 7s = 81

We put the value of a = 13

3(13) + 7s = 81

39 + 7s = 81

7s = 81 - 39

7s = 42

s = 42/7

s = 6

Students ticket cost $6
