Hey there!

2.7 * 10^4 + 120

10^4

= 10 * 10 * 10 * 10

= 100 * 100

= 10,000

2.7 * 10,000 + 120

= 27,000 + 120

= 27,120

Therefore, your answer is. [10,000 * 2.712] because 10,000 * 2.712 is approximately 27,120

Good luck on your assignment and enjoy your day!

7. Sapna travelled 48 km to meet her parents. She travelled the first 18 km by car and the remaining distance by train. Find the

Anton [14]

The fraction of the journey Sapna traveled by car and train is 3/8 and 5/8 respectively.

We know that fraction is an expression in mathematics used to denote the division of two whole numbers.

Given that the total distance = 48 km.

The distance Sapna traveled by car = 18 km.

So, the fraction is = distance traveled by car/total distance = 18/48 = 3/8

The distance Sapna traveled by train = 48 - 18 km = 30 km.

So, the fraction is = distance traveled by train/total distance = 30/48 = 5/8

Therefore the fraction of the journey Sapna traveled by car and train is 3/8 and 5/8 respectively.

The conference table top shown is the shape of two congruent trapezoids. The table top is wooden with a rectangular glass inset.

Papessa [141]

I think it’s 196? base 1 +base 2=28 radius is 7 but we need the whole thing so 7x2=14.
then multiply and then divide by 2 28X14= 392 divided by 2 = 196

Answer:

B: II, IV, I, III

Step-by-step explanation:

We believe the proof <em>statement — reason</em> pairs need to be ordered as shown below

Point F is a midpoint of Line segment AB Point E is a midpoint of Line segment AC — given

Draw Line segment BE Draw Line segment FC — by Construction

Point G is the point of intersection between Line segment BE and Line segment FC — Intersecting Lines Postulate

Draw Line segment AG — by Construction

Point D is the point of intersection between Line segment AG and Line segment BC — Intersecting Lines Postulate

Point H lies on Line segment AG such that Line segment AG ≅ Line segment GH — by Construction

II Line segment FG is parallel to line segment BH and Line segment GE is parallel to line segment HC — Midsegment Theorem

IV Line segment GC is parallel to line segment BH and Line segment BG is parallel to line segment HC — Substitution

I BGCH is a parallelogram — Properties of a Parallelogram (opposite sides are parallel)

III Line segment BD ≅ Line segment DC — Properties of a Parallelogram (diagonals bisect each other)

Line segment AD is a median Definition of a Median

During a 20% off sale, the sale price of a bluetooth radio was $33.96. What was the regular price?

SVETLANKA909090 [29]

20% of the regular price was off.

So 80% of the regular price stayed on.

$33.96 was that 80% of the regular price.

(0.8) · (regular price) = $33.96

Divide both sides by (0.8).

Regular price = ($33.96) / (0.8)

<em>Regular price = $42.45</em>
