Answer:

False

Step-by-step explanation:

10 – [50 ÷ (-2 x 25) -7] x 22 = -18

10 - (50 ÷ (-50)-7) x 22= -18

10 - (-1 - 7) x 22= -18

10 - (-8) x 22 = -18

10 + 8 x 22 = -18

10+176=-18

186=-18

Vika [28.1K]

Answer:

7238 rounded to the nearest whole number.

Step-by-step explanation:

Hence, the volume is

\frac{4}{3} \pi \times  {12}^{3}

Please Find the distance between the two points rounding to the nearest tenth (if necessary).
Sphinxa [80]

Answer:

10.29 u

Step-by-step explanation:

<u>Given :- </u>

  • Two points (7,4) and (-2,9) is given to us.

And we need to find out the distance between the two points . So , here we can use the distance formula to find out the distance. As,

:\implies D = √{(x2-x1)² + (y2-y1)²}

:\implies D =√[ (7+2)² +(9-4)²]

:\implies D =√[ 9² +5²]

:\implies D =√[ 81 +25]

:\implies D = 10.29

<h3>Hence the distance between the two points is 10.29 units .</h3>

I am Lyosha [343]

9514 1404 393

Answer:

  D.  -17%

Step-by-step explanation:

The change from March to April is (April - March) = (100 -120) = -20. As a fraction of the March bill, that is ...

  -20/120 = -1/6

As a percentage, that change is ...

  -1/6 × 100% ≈ -16.667% ≈ -17%

The electric bill changed by about -17% from March to April.

_____

<em>Additional comment</em>

Water went up 4%; groceries went up about 14%, and restaurant changed by -15%.

The percentage change is found by ...

  % change = ((new amount)/(original amount) -1) × 100%

Above, we have rearranged this to ...

  % change = ((new amount) -(original amount))/(original amount) × 100%
