Answers

Answer 1
Answer:

Answer:

11

Step-by-step explanation:

The given expression is as following:

((-8) - ((-14)/(-7) )^3)*(-3)+(-3)-34

According to PEMDAS

calculate the process at the Parentheses first then the exponent.

So,

= ((-8) - (2 )^3)*(-3)+(-3)-34\n= ((-8) - 8)*(-3)+(-3)-34\n=(-16)*(-3)+(-3)-34\n=48+(-3)-34\n=48-3-34\n=11

Answer:

x = 4.8

Step-by-step explanation:

(x)/(-12)=-0.4\qquad\text{multiply both sides by (-12)}\n\n-12\!\!\!\!\!\diagup^1\cdot(x)/(-12\!\!\!\!\!\diagup_1)=(-12)(-0.4)\n\nx=4.8

Answer:

X=4.8

Step-by-step explanation:

Isolate x on one side of the equation.

x/-12=-0.4

x(-12)/-12=(-0.4)(-12) (First, multiply by -12 from both sides.)

(-0.4)(-12) (Solve.)

(-0.4)(-12)=4.8

x=4.8

So, the final answer is x=4.8.

sebuah taman berbentuk persegi panjang dengan keliling (2x+24)m dan lebar (8-x)m. agar luas taman maksimum, panjang taman tersebut adalah....m

Answers

2(8-x) = 16-2x (because there are 2 width lengths in the whole perimeter (circumference).
2x+24 - 16-2x =8 (the x's cancel each other out)
8/2 = 4 (because the length is in 2 parts so they are each 4)
The length of the garden is 4m
Hope this helps :)

Carla walked 5/6 of a mile last weekend, she walked 1/3 as far this weekend.how many miles did carla walk this weekend?

Answers

To do this multiply the fractions.  Multiply the fractions because she walked 1/3 as far as last weekend,  so she walked 1/3 of what she walked,  and multiplying will help you find the answer.
5*1=5
6*3=18
5/18 is the answer
To do this, first convert 1 mile to 5280 ft to make it easier. Now to find 5/6 of 5280 (remember 'of ' means to multiply) turn 5/6 into .833333 (3 repeating) and multiply that by  5280 to get 4400. That means last weekend Carla walked 4400 ft. Now to find what she walked this weekend, turn 1/3 into .33333 (3 repeating) and multiply that by 4400. You should get 1466.6666 ( 6 repeating) or 1466 and 2/3 ft as the distance Carla walked this weekend.

You've been working with rectangular prisms all night, and the same formula gives the volume of every one of them.  Unfortunately, you used way more time asking other people for answers than it would take you to solve them on your own.

The formula is:

             Volume  =  (length)  times  (width)  times  (height) .

With that formula, you can directly solve problems #1, #2, #3,
#4, and #8.  It's also the only math you really need to solve #9 ...
but you also need to use your brain cells for #9.


For #6, start with the same formula:

                                     Volume = (length) x (width) x (height)

Divide each side by
(width) x (height), and
then it says:               Length = (volume) / (width x height) .

#6 gives you the volume, width and height. 
 You can just write them into this equation,
and bada-bing, you'll have the missing length.

HELP ME! I'm confused if to whether I should choose a or b

' B ' says that he starts with $50,000and then loses $100 for each computer he sells.

If he sold 500computers with that equation, his total income would be zero.

The only way he could earn$75,000 from that equation would be to sell
(negative 250) computers.That would be quite a trick, so it's most likely not 'B'.
