Answer: NiCl2 + Fe

Iron is above nickel in the activity series, so iron will replace nickel like this:

NiCl2 + Fe → FeCl2 + Ni

Cu(OH)2 is insoluble, so it will form a precipitate.

Answer:

If they are divisible by the numbers in the original shape, then try and see if the others sides of the scaled copy are scaled by the same factor. If they are, then they are a scaled copy.

Answer:

√ 42  lies between  6  and  7

Step-by-step explanation:

We know that  √ 42  will lie between  √ 36  and  √ 49

And  √ 36 = 6  ;  √ 49 = 7

Hence we can be sure that  √ 42  lies between 6  and  7

Answer:

Step-by-step explanation:

−2 1/6 divided by 1 1/4:

1) to divide that mixed number we'll need to turn it into an improper fraction:

[tex] - 2\frac{1}{6} = - ( \frac{6 \times 2 + 1}{6} ) = - \frac{13}{6} \\ 1 \frac{1}{4} = \frac{4 \times 1 + 1}{4} = \frac{5}{4} [/tex]

2) now let's divide it, reciprocating 1 1/4 and multiplying both fractions one by another:

[tex] - \frac{13}{6} \times \frac{4}{5} = - \frac{52}{30} = - \frac{26}{15} [/tex]

3) Hence the answer is -26/15

Answer:

1/8

Step-by-step explanation:

1/8 + 1/2 + 1/4 = 1/8 + 4/8 + 2/8 = 7/8

so 1/8 remains

Answer:

0.9545

Step-by-step explanation:

Given that :

Mean (m) = 120

Standard deviation (s) = 12

what percentage of values is within the interval 96 to 144

P(96 < x < 144)

P(x < 96)

obtain the standardized score (Z) :

Z = (x - m) / s

Z = (96 - 120) / 12 = - 2

p(Z < - 2) = 0.02275 ( Z probability calculator)

P(x < 144)

obtain the standardized score (Z) :

Z = (x - m) / s

Z = (144 - 120) / 12 = 2

p(Z < - 2) = 0.97725 ( Z probability calculator)

p(Z < - 2) - p(Z < 2) = 0.97725 - 0.02275 = 0.9545

Explanation:

Choice A is a reflection. Choice C is a rotation. Reflections and rotations are isometries because they preserve the same shape and size of the original figure. Translations are the third type of isometry.

Choice B is not an isometry. It looks like an extra point is added along with extra line segments. The before and after figures are completely different.

Answer:

The total distance traveled by the car is 330 miles.

Step-by-step explanation:

The circular track is the circumference of circle with radius 1.5 miles.

Circumference of a circle = 2[tex]\pi[/tex]r

Thus,

Circumference of the track  = 2 x [tex]\frac{22}{7}[/tex] x 1.5

                           = 9.4286571429

Circumference of the track = 9.4286571429 miles

But, one complete revolution by the car is the circumference of the track.

i.e One complete revolution round the track = 9.4286571429 miles

Therefore,

35 complete revolutions round the track = 35 x 9.4286571429 miles

                                       = 330 miles

The total distance traveled by the car is 330 miles.

Answer:

The width is 69m

Step-by-step explanation:

Set it up in a equation, W x 99 = 6831. So first thing to do is get the letter by its self. So you will do the opposite of multiplication. And what you do to one side you do to the other so you divide 6831 by 99. And you get W = 69

Answer:

Step-by-step explanation:

Area of rectangular field = length × width 99×w=6831

w = 6831/99

w=69m

Answer:

30 markers

Step-by-step explanation:

Answer: = 62.8 pounds of CO₂

Step-by-step explanation:

1 kilowatt per hour produces 0.99 pounds of C02.

The total wattage in hours used was;

= 7,043 * 9 hours

= ‭63,387‬ watts

In kilowatts;

= ‭63,387‬/1000

= 63.387 kilowatts

CO2 produced;

= 63.387 * 0.99

= ‭62.75313‬

= 62.8 pounds of CO2
