$2.39 * 2 (jars of peanut butter) = $ 4.78. $4.78 - $1 (discount because of the coupon when buying 2 jars of peanut butter) is equal to $3.78. Therefore, the final price of the two jars is $ 3.78.

To simply put -
($2.39 * 2) - $1 = $3.78

Answer:  165 combination can be possible.

Step-by-step explanation:

Here, According to the question,

Different types of machines in the weight room  in gym = 11

And, . Geoff has time to use only 3 of them this afternoon.

Therefore, total number of different combination of machine can geoff choose from to use

= 11_C_3

= \frac{11!}{3!\times (11-3)! }     ( because n_C_r = \frac{n!}{r!(n-r)!} )

= \frac{11!}{3!\times 8! }

= \frac{11\times 10\times 9\times 8!}{6\times 8! }

=\frac{11\times 10\times 9}{6}

= \frac{990}{6}

= 165

The hypotenuse of a 45°-45°-90° triangle measures 4 cm. What is the length of one leg of the triangle? 2 cm 2 StartRoot 2 EndRoo
Oxana [17]

Answer:

2\sqrt{2} cm

Step-by-step explanation:

In order to solve this you just have to remember the formula for the sides and hypotenuse of the triangle rectangle:

c^{2} =a^{2} +b^{2}

Since A and B are equal we will use X to represent them both:

c^{2} =a^{2} +b^{2}\\4^{2} =x^{2} +x^{2}\\16 =2x^{2}\\8=x^{2} \\x=\sqrt{8}=\sqrt{4*2}=2\sqrt{2}

ANd by solving the equation we get that the length of the legs of the triangle rectangle with a hypotenuse of 4cm is 2\sqrt{2} cm

What is the value of?<br> –4<br> –2<br> 2<br> 4
Oliga [24]

Answer:

2 is your answer.

Step-by-step explanation:

Simplify. Remember to follow PEMDAS. First solve the parenthesis, then multiply, and finally divide.

-8(17 - 12) = -8(5) = -40

-2(8 - (-2)) = -2(8 + 2) = -2(10) = -20

-40/-20 = 2

2 is your answer.
