Since the area of one side of a cube is 64, you can find the surface area by adding the rest of the 5 sides which is:
64+64+64+64+64+64=384

3. Jessica is awake 2/3 of the day. She spends 5/8 of this time at home
ruslelena [56]

Answer:  a. 5/12     b. 10 hours

Step-by-step explanation:

5/8 x 2/3 = 10/24 = 5/12

she spends 5/12 of the day awake at home

if a day has 24 hours then 5/12 of that is 5/12 x 24 = 10

so she spends 10 hours awake at home

Whats -2(4k-7)=22-8k in Algebra
Andrei [34K]

Let's solve your equation step-by-step.

−2(4k−7)=22−8k

Step 1: Simplify both sides of the equation.

−2(4k−7)=22−8k

(−2)(4k)+(−2)(−7)=22+−8k(Distribute)

−8k+14=22+−8k

−8k+14=−8k+22

Step 2: Add 8k to both sides.

−8k+14+8k=−8k+22+8k

14=22

Step 3: Subtract 14 from both sides.

14−14=22−14

0=8

So, the answer is 0=8.

Work out the lengh of RS <br> gue your answer to 3 significant figures
atroni [7]

Answer:

RS ≈ 5.83 units

Step-by-step explanation:

Calculate RS using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = R(- 3, 1) and (x₂, y₂ ) = S(2, 4)

RS = \sqrt{(2+3)^2+(4-1)^2}

     = \sqrt{5^2+3^2}

     = \sqrt{25+9}

     = \sqrt{34} ≈ 5.83 ( to 3 significant figures )
