Answer:

$57.40

Step-by-step explanation:

To find the discount you do

82 times .30

which equals

24.6

that is how much the discount takes off the price

then you do

82 - 24.6

= 57.4

= 57.40

Hope this helps dude

Answer:

$57.40

Step-by-step explanation:

There are two different ways to solve this, so I’ll explain both of them in case you need them in the future!

(1) Case 1:

Since 100% of $82.00 is $82.00, and we want to find the price when 30% is not included, there is 100%-30% = 70% of the initial cost in the final answer. We can multiply $82.00 by the decimal equivalent of 70/100 (0.7) to find that the discount makes the cost $57.40!

(2) Case 2:

To take a bit of a longer approach, you can calculate what 30% of the cost of $82.00 is by multiplying:

$82.00 x 30/100 = $24.60

Then, you would take that discount off of the initial cost:

$82.00 - $24.60 = $57.40

Answer:

(a) 8 x(5 x-6)=40 x^{2}-48 x

(c) \begin{aligned}(x-3)(5 x-6) &=5 x^{2}-21 x+18\end{aligned}

Step-by-step explanation:

(a) To find verify the answer we need to multiplying the equation 8 x(5 x-6)

8 x(5 x-6)=40 x^{2}-48 x

Thus, this statement is true.

(b) To find verify the answer we need to multiplying the equation -4 x\left(2 x^{2}+1\right)

-4 x\left(2 x^{2}+1\right)=-8 x^{3}-4 x

Hence, the given statement is false.

(c) To find verify the answer we need to multiplying the equation (x-3)(5 x-6)

\begin{aligned}(x-3)(5 x-6) &=5 x^{2}-6 x-15 x+18 \\&=5 x^{2}-21 x+18\end{aligned}

Hence, the given statement is true.

(d) To find verify the answer we need to multiplying the equation(2 x+3)\left(x^{2}+3 x-5\right)

\begin{aligned}=(2 x+3)\left(x^{2}+3 x-5\right) &=2 x^{3}+6 x^{2}-10 x+3 x^{2}+9 x-15 \\&=2 x^{3}+9 x^{2}-x-15\end{aligned}

Hence, the given statement is false.

Pick out the set of numbers that is not Pythagorean triple
Zielflug [23.3K]

Answer:

\huge\boxed{9,40,46}

Step-by-step explanation:

<u><em>Let's check it using Pythagorean Theorem:</em></u>

c^2 = a^2 + b^2

Where c is the longest sides, a and b are rest of the 2 sides

1) 9 , 40 , 46

=> c^2 = a^2 + b^2

=> 46^2 = 9^2 + 40^2

=> 2116 = 81 + 1600

=> 2116 ≠ 1681

So, this is not a Pythagorean Triplet

2) 16, 30 and 34

=> c^2 = a^2 + b^2

=> 34^2 = 16^2 + 30^2

=> 1156 = 256 + 900

=> 1156 = 1156

No need to check more as we've found the one which is not a Pythagorean Triplet.
