|4 - 5 + 10| = * what is the value?

Answer:

Whenever you want to zoom and enlarge a photo so you can see details, you are using a dilation transformation.

At eye exams, the pupil dilates (widens), allowing in more light and giving your doctor a better view of the back of your eye.

When you build model airplanes, cars, or buildings that are true in scale and measurement, you are performing a dilation.

And even your shadow is a dilation as well.

Answer:

678.24

Step-by-step explanation:

First, we have to find the area of 1 cylinder(pi x r^2 x h), which i got as 226.08 then we multiply by 3 because there are 3 cylinders. 226.08 x 3 = 678.24

Answer: Hope this helps you!

Step-by-step explanation:

First, I started off with the equation of the area of a cylinder

Area = π * radius^2 * height

Now I will go on and substitute

Area = 3.14 * 3^2 * 8

And now I will start solving

Area = 3.14 * 3^2 * 8

(3^2 = 3*3 = 9)

Area = 3.14 * 9 * 8

(9*8 = 72)

Area = 3.14 * 72

Area = 226.08

The area of 1 cylinder is 226.08, however we need to find the area of the whole composite figure which is made up of 3 cylinders.

226.08 * 3 = 678.24

Here are the pairs matched with their products:

- (-5)(4.2) matches with -21

- (-7)(-3) matches with 21

- (2.5)(-9) matches with -22.5

Pairs (4) and (5) do not have corresponding products in the given options.

Answer:

The enthalpy change per mole of sodium when sodium reacts with water is 28.36 kJ

Step-by-step explanation:

The given parameters are;

Mass of sodium = 8 grams = 0.008 kg

Volume of water = 227 cm³ = 0.000227 m³

Initial water temperature, T₁ = 298 K

Final water temperature, T₂ = 308.4 K

Specific heat capacity of water = 4.18 J/(K·g)

Density of water = 1000 kg/m³

Mass of water = 1000×0.000227 = 0.227 kg = 227 g

Heat change, ΔH = m×c×ΔT = m×c×(T₂ - T₁)

ΔH = 227*4.18*(308.4 - 298) = 9868.144 J = 9.868 kJ

Molar mass of sodium = 22.989769 g/mol

Therefore, 8 grams contains;

8/22.989769 = 0.348 moles of Na

Which gives the enthalpy change per 0.348 moles of Na when sodium reacts with water = 9.868 kJ

Therefore, when one mole of Na reacts with water we have;

The enthalpy change per 0.348/0.348 = 1 mole of Na when sodium reacts with water = 9.868 kJ/0.348 = 28,358.3 J = 28.36 kJ.

Answer:

The expressions are not equivalent due to the fact that if you were to substitute real numbers you would not get equivalent answers.

Step-by-step explanation:

If you substitute with real numbers, it helps you to get a better view of the equation.

Say you plug in x=5.

5+5 = 5(5)

10=25

The answers are not equivalent.

Answer:

25

Step-by-step explanation:

4a +12 -2c + c

4( ) + 12 - 2( ) + ( )

4(4) + 12 - 2(3) + 3

16 + 12 - 6 + 3

28 - 6 + 3

22 + 3

25

Helping in the name of Jesus.

Therefore,  4a  +   12   -   2c   +   c  =   25

       a  =   4  

       c  =   3

        4a  +   12   -   2c   +   c

       (4)(4)  +  12  -     (2)(3)   +    3

         16     +   12   -   (2)(3)   +    3

         28      -            (2)(3)    +    3

         28     -   6     +     3

         22    +      3   =   25

Draw a conclusion:

     4a  +   12   -   2c   +   c   =  25

I hope this helps!

2 1/3 lego planes

Step-by-step explanation:

3 1/2 = 3.5

we cross multiply

x = amount of lego planes

xlego x 60 = 3.5 x 40

3.5 x 40 = 140

140 ÷ 60

Answer:

It is 6x13

Step-by-step explanation:

you would multiply the length which is 13 times the height. The 8 is slanted so you wouldn’t multiply that. The 6 is a straight line so that is the correct height

Answer:

13*6=78 cm^2

Step-by-step explanation:

8 is redundant in this question, it's just there to throw you off and you don't need it.

To get the area of a parallelogram, multiply the base by the height.

13*6=78

I just counted the 12 outcomes and the 2 same sex possibilities, which would turn to 2/12, and then simplified it into 1/6. I hope this is right, I am very sorry if it isn't.

Answer:

A

Step-by-step explanation:

If you do 876 divided by 24, you would get 36.5. Because the divisor is 24, and you got 36.5, that would mean in remainders, you would get 36 with a remainder of 12.
