Answer:

The leg measures 14.14 cm

Step-by-step explanation:

The "40 - 40 - 90" special right triangle is an isosceles right triangle because two angles measures the same. (Check the picture)

The legs are the same.

The hypotenuse is:

a × √2

From the question, the length of the hypotenuse is 20 cm.

20 = a × √2

20 ÷ √2 = a

a = 10√2 ≈ 14.14 cm

Given that Segment BE is 5 units, find the indicated measures for each
zalisa [80]

Answer:

The indicated measure of the length of AE = 5 units

Step-by-step explanation:

To determine:

What is the indicated measure of length?

Information Fetching and Solution Steps:

From this single diagram, it seems the indicated measure of length which we have to determine is the length of AE.

Given that Segment BE is 5 units. i.e. BE = 5 units

  • As the square has two equal diagonals AC and DB which meet at point E.
  • So, point E being the common mid-point of both diagonals.

As both of the diagonals of square are equal in length.

And the length of BE is 5 units, which is half the length of BD. It means the diagonal BD has a length of 10 units.

And since both diagonals  AC and DB are equal in length, it means the length of AC must be 10 units.

Since, AC has the length of 10 units, it means the length of AE must be half of the length of AC. Thus, the indicated measure of the length of AE is 5 units.

Therefore, the indicated measure of the length of AE = 5 units

For a camping trip, three scoutmasters are each driving a portion of the 150 miles to campground mr. Jimenez drives 3/10 of the
babymother [125]

Answer:

45 miles

Step-by-step explanation:

Jimenez drives 3/10 of the distance:  (3/10)(150 miles) = 45 miles.

Mr. Robertson drives 2/5 of the distance:  (2/5)(150) = 60 miles.

These two people drive 105 miles total.

Mr. Weatherly drives the rest:  (150 miles - 105 miles) = 45 miles.

DochEvi [55]

→Amount charged by wireless service provider when 'm' messages are sent=$(30+0.10 m)

Amount charged if ' 1 ' messages are sent= $30+0.10×1=$30.10

Amount charged when '2' messages are sent=$30+0.10×2=%30.20

.....................................................

Amount charged or money you will pay when 'u' messages are sent=$30+0.10×u=$(30+0.10 u)

3102 base 4 to base 2 *show work please*
Shalnov [3]
3102 base4 = 3x4^3+ 1x4^2 + 2x1 = 3x64 + 1x16 + 2 = 210 base10
The powers of 2 are 2, 4, 8, 16, 32, 64, 128, 256
210 = 128 + 64 + 16 + 2 = 2^7 + 2^6 + 2^4 + 2^1 = 11010010 base2

A faster method is to each digit in base 4 to two digits in base 2
3 base4 = 11 base2
1 base4 = 01 base2
0 base4 = 00 base2
2 base4 = 10 base2
So 3102 base4 = 11010010 base2

If you wanted to convert base 4 to (say) base 5 you would need the first method and convert to base 10 first
