Studying mathematics in the night is better than the morning study and why?

1 answer:

6 0

Honestly, I believe you should study while you're still up (if it's not too late). Your brain isn't really awake that early in the morning and you might not even remember anything. If you have have a test later in the day, study through out your classes and lunch and you should be fine. Another tip is to go with you gut instinct. Don't second guess yourself because that can mess you up.

Given cube inscribed in sphere with edges √243 cm. Find the volume of sphere

g100num [7]

Answer:

10,300.77 cm³

Step-by-step explanation:

Radius = ½(diameter)

Diagonal:

sqrt[243 + 243]

sqrt(486)

Diameter

sqrt(486 + 243)

Radius: 27/2

Volume of sphere:

4/3 × pi × r³

4/3 × 3.14 × (27/2)³

10300.77 cm³

Solve and check: 1 x + 3 = x + 10 x − 2 From least to greatest, the solutions are x = and x = .

blondinia [14]

Answer:

x= 1/2

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

1x+3=x+10x−2

x+3=x+10x+−2

x+3=(x+10x)+(−2)(Combine Like Terms)

x+3=11x+−2

x+3=11x−2

Step 2: Subtract 11x from both sides.

x+3−11x=11x−2−11x

−10x+3=−2

Step 3: Subtract 3 from both sides.

−10x+3−3=−2−3

−10x=−5

Step 4: Divide both sides by -10.

−10x/−10=−5/−10x=1/2

What is the exact circumference of a circle with a radius of 12 inches?

Anestetic [448]

We can get the circumference of any circle in terms of the radius with this formula. C = 2 $\pi$ r.

Where r is the radius of the circle.

And we will use 3.14 for $\pi$ .

Plug in all the values.

C = 2 * 3.14 * 2

C = 12.56

So, the circumference of the circle is 12.6 inches when rounded to the nearest tenth.

Answer:

Step-by-step explanation:

let x and y be the number of chip and pretzel bags respectively : 4x%2B2y%3 C=20 : if x=1 then 4%281%29%2B2y%3C=20--->{{2y<=16}}}--->y%3C=8 : if x=3 then 4%283%29%2B2y%3C=20--->{{2y<=8}}}--->y%3C=4 : so chips 1 and pretzels 8 : chips 3 and pretzels 4.
