<h2>Answer:</h2>

Ques 1)

The student whose measurement might be in centimeters is:

                         Jim

Ques 2)

                 C.   5,000

<h2>Step-by-step explanation:</h2>

Ques 1)

We know that the standard unit centimeters or meters is used to represent the length of some object.

Here Jim measured an object's length.

Hence, he would represent his measurement in centimeters.

Ques 2)

We know that  1 m=100 cm

and 1 km=1000 m

Hence,

1 km=100000 cm

Hence,

0.05 km=0.05×100000 cm

Hence, we have:

0.05 km=5000 cm.

Hence, the correct answer is: Option: C

Parallelogram<br> b=12 cm, h=10 cm, a=
Anna35 [415]
Answer: 120 cm^2

Step-by-Step Explanation:

Base (b) = 12 cm
Height (h) = 10 cm
Area (a) = bh

Therefore,
= bh
= b * h
= 12 * 10
=> 120

Area (a) = 120 cm^2

I have two proof questions and I don't really know how to do them.
goldfiish [28.3K]

\angle1\cong\angle2 corresponding angles, therefore

m∠1 = m∠2 → m∠2 = 130°

\angle2\cong\angle3 vertical angles, therefore

m∠2 = m∠3 → m∠3 = 130°


If ∠1 and ∠2 are complementary, then m∠1 + m∠2 = 90°.

If ∠2 and ∠3 are complementary, then m∠2 + m∠3 = 90°

Therfore

m\angle1 + m\angle2 = m\angle2 + m\angle3\qquad|\text{subtract}\ m\angle2\ \text{ from both sides}\\\\m\angle1 = m\angle3\to\angle1\cong\angle3

The volume of a cube is 27 cubic meters.<br> What is its surface area, in square meters?
stiks02 [169]

Step-by-step explanation:

the volume of a cube is

side³.

since the volume is 27 m³, the individual side lengths are then the cubic root of 27 = 3 m.

the surface area is 6 squares of 3×3 = 9m², so in total

9 × 6 = 54 m²

your customer count for last week was 5417. Due to a product promotion you expect a 2.4% increase this week over last week. how
Sauron [17]
The answer would be 5547
First you multiply 5417 and 2.4% to get 130.008
Then you add 130.008 and 5417 to get 5547.008
but you can round this to 5547
Hope this helped! :)
