Answer: The surface area of the cube is 385 mm^2.

When we are finding the surface area of a shape, we need to add up all the areas of each face. In this case, there are 6 faces.

Each face is the shape of square with sides of 8 mm. So the area of each face is 8 x 8 = 64 square mm.

Since we have 6 faces, we will multiply 64 by 6 to get 384 mm^2 in all.

What is the unit rate for 180 miles in 3 hours
Ugo [173]

Hello

Answer:

60 miles per hour

I have given a detailed explanation of the logic behind this.

Explanation:

Consider the structure of the wording: "miles per hour"

The word "per" means for each. There is you clue.

Each is, one of and one of is unit measurement

So the controlling element in this question is that you need to convert the 3 hours into 1 hour.

Using ratio properties

180

3

=

x

miles

1

hour

We need to 'force' the left hand side into the same form as the right. That is: we need to convert the denominator into 1 and see what happens to the numerator.

⇒

180

÷

3

3

÷

3

=

x

1

⇒

60

1

=

x

1

So the unit rate of speed is  

60

miles

per

−−−

hour

Last Saturday, Niki went on a bike ride from her house to the park. The total distance she travelled on her bike was 3 1/5 miles
Mnenie [13.5K]

Answer:

D. \frac{16}{5}

Step-by-step explanation:

3\frac{1}{5}

To rewrite a mixed number as an improper fraction, first, multiply the whole number by the denominator.

3*5=15

Then, add this number to the numerator.

15+1=16

This number is now the numerator of the fraction. The denominator stays the same.

\frac{16}{5}

I hope this helps!

Graph the numbers that are solutions to both inequalities.
nadya68 [22]

Answer:

p ∈ [5 , 6)

Step-by-step explanation:

p + 6 ≥ 11

⇒ p ≥ 11 - 6

⇒ p ≥ 5

⇒ p ∈ [5 , +∞)

3p < 18

⇒ p < 18/3

⇒ p < 6

⇒ p ∈ (-∞ , 6)

Then

p the solution to both equations verify:

p ∈ (-∞ , 6) ∩ [5 , +∞)

Conclusion :

p ∈ [5 , 6)
