PLEEEEEEEEEASE HELP!!!

The only way to really tell is to check it with the Pythagorean Theorem.

The Pythagorean Theorem describes every right triangle, and every triangle that fits the Pythagorean Theorem has a right angle in it.  Guaranteed.  This is incredibly handy.

If this IS a right triangle, then

(one leg squared) + (the other leg squared) = (the hypotenuse squared) .  

Let's check it out:

--  One leg squared = (11 cm)²  .  That's  121 cm² .

--  The other leg squared = (√99 cm)² .  That's  99 cm²  .

--  Their sum is  (121 + 99) cm² .  That's  220 cm² .

-- The hypotenuse squared is  (15 cm)² .  That's  225 cm² .

Is  220 cm² equal to  225 cm² ?

NO !  They are not equal.  They are different !

The sum of the squares of the legs is NOT equal to the square of the hippopotamus.

==>  This triangle does NOT fit the Pythagorean Theorem.

==>  It is NOT a right triangle.

(The angle in the bottom corner is slightly bigger than 90°.  But you can't tell by looking at it.  It's so close that you can only tell by checkoing the lengths againt the Pythagorean Theorem.)

Answer: x=90

Step-by-step explanation: Okay let's see! Let's solve your equation step-by-step.

x

42

=

15

7

Step 1: Cross-multiply.

x

42

=

15

7

x*(7)=(15)*(42)

7x=630

Step 2: Divide both sides by 7.

7x

7

=

630

x=90

Answer:

x = 90

Step-by-step explanation:

7x = 42 * 15 = 630

x = 630/7

x = 90

Answer:

1.    x = 1, y = 2.

12.  x = 1, y = -3.

Step-by-step explanation:

I won't do all these for you, just the first and the last. The method is similar  for all 12.

1.

y = x + 1

x + y = 3

Substitute y = x + 1 into the second equation:

x + y = 3 so:

x + (x + 1) = 3

2x + 1 = 3

2x + 1 -1 = 3 - 1

2x = 2

x = 1.

Now substitute x = 1 into the first equation to get the value of y:

y = x + 1

y = 1 + 1

y = 2.

12.

4x = y + 7

3x + 4y + 9 = 0

Solve for y in the first equation:

4x = y + 7                Subtract 7 from both sides of the equation:

4x - 7 = y + 7 - 7

y = 4x - 7.

Now substitute  y = 4x - 7 in the second equation:

3x + 4y + 9 = 0   so:

3x + 4(4x - 7) + 9 = 0

3x + 16x - 28 + 9 = 0

19x - 19 =  0

19x - 19 + 19 = 0 + 19

19x = 19

x = 19/19 = 1.

Now substitute x = 1 in the first equation:

4x = y + 7

4*1 = y + 7              Subtract 7 from both sides of the equation:

4 - 7 = y + 7 - 7      

-3 = y.

Answer:

[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{k = 3}}}}}[/tex]

Step-by-step explanation:

[tex] \sf{4.5 + 1.5k = 18 - 3k}[/tex]

Move 3k to left hand side and change it's sign

Similarly, move 4.5 to right hand side and change it's sign

[tex] \longrightarrow{ \sf{1.5k + 3k = 18 - 4.5}}[/tex]

Collect like terms

[tex] \longrightarrow{ \sf{4.5k = 18 - 4.5}}[/tex]

Subtract 4.5 from 18

[tex] \longrightarrow{ \sf{4.5k = 13.5}}[/tex]

Divide both sides by 4.5

[tex] \longrightarrow{ \sf{ \frac{4.5k}{4.5} = \frac{13.5}{4.5} }}[/tex]

Calculate

[tex] \longrightarrow{ \sf{k = 3}}[/tex]

Hope I helped!

Best regards! :D

Answer:

k = 3

Step-by-step explanation:

Subtract 4.5 from both sides:

4.5 + 1.5k = 18 - 3k

-4.5            -4.5

1.5k = 13.5 -3k

Subtract -3k from both sides:

1.5k = 13.5 - 3k

+3k             +3k

4.5k = 13.5

Now simplify:

4.5k = 13.5

k = 3

Answer:

41.5÷5= the answer 8.3 cm

Answer:

8, 10, 12

Step-by-step explanation:

Because they are even there is a whole number x so that (1st)2x, (2nd) 2x+2, and (3rd)2x+4 are the 3 consecutive integers.

so

If the third is 8 less than twice the 2nd then:

 3rd   = 2 (2nd) - 8

2x + 4 = 2 (2x+2) - 8

2x + 4 = 4x + 4 - 8

2x + 4 = 4x - 4         Add 4 to each side

2x + 4 + 4 = 4x - 4 + 4

2x + 8 = 4x    Subtract 2x from each side

2x - 2x + 8 = 4x - 2x

8 = 2x         Divide each side by 2

8/2 = 2x/2

8/2 = x

4 = x

No we plug into our equations to find the integers.

2x = 2(4) = 8    

2x + 2 = 2(4) + 2 =  8 + 2 = 10              

2x + 4 =  2(4) + 4 =  8 + 4 = 12

So our integers are 8, 10, 12

Hey there!

[tex]3+22=2+3[/tex]

So let's first add 3 + 22.

Now we have to add 2 + 3.

[tex]2+3=5[/tex]

So that means the answer to this is:

[tex]25=5[/tex]

This is false because [tex]25[/tex] is not equal to [tex]5[/tex].

Answer:

x = 4, TU = 22

Step-by-step explanation:

Given that TS bisects TU at Q , then

TQ = QU , substitute values

5x - 9 = 15 - x ( add x to both sides )

6x - 9 = 15 ( add 9 to both sides )

6x = 24 ( divide both sides by 6 )

x = 4

Thus

TU = 5x - 9 + 15 - x = 4x + 6 = 4(4) + 6 = 16 + 6 = 22

Answer:

Step-by-step explanation:

The total cost of the leash will be $22.90. The correct option is A.

The Percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

Given that Kirk finds a dog leash with a price tag of $24 at a pet store. The leash is 10% off the original price. He must also pay 6% sales tax.

The cost after 10% off is:-

Cost = 24 - 24 x ( 10 / 100 )

Cost = 24 - 2.4

Cost = 21.6

Total cost after 6% sales tax = 21.6 + ( 21.6 x 0.06)

Total cost after 6% sales tax = 21.6 + 1.296 = $22.9

Therefore, the total cost of the leash will be $22.90. The correct option is A.
