Well first you have to figure out how many feet are in a yard. Answer is 3 then minus 3/4 or 75% which will give you 2.25 feet. Then do
1 / 2 of (2.25 feet) = 1.125 feet.

Answer:

\frac{3}{8} yards

Step-by-step explanation:

Length of the piece of the ribbon = \frac{3}{4} yards

Nora will use \frac{1}{2} of it to make a bow

i.e \frac{1}{2} of  \frac{3}{4}

Now the actual length of the ribbon will she use for the bow can be calculated  as :

= \frac{1}{2} *\frac{3}{4}

= \frac{3}{8}

Therefore, the length of the ribbon will she use for the bow = \frac{3}{8} yards

In ΔABC, m∠ACB = 90°, CD ⊥ AB and m∠ACD = 45°. Find: a Find CD, if BC = 3 in
Elodia [21]

Answer:

  CD = (3/2)√2

Step-by-step explanation:

All the triangles are similar isosceles right triangles, so the hypotenuse in each case is √(1²+1²) = √2 times the length of the corresponding legs. BC is the hypotenuse of ΔBCD, so leg CD is that length divided by √2.

  CD = BC/√2 = 3/√2

  CD = (3/2)√2

Help me please!!! its in the picture
Sonja [21]

Hi, I'm happy to help!

First, we need to find BC. We know, because B is the midpoint of AC, that AB and BC are congruent, or the same length. We are told that AB is 3.

<u>So, BC is 3 also.</u>

Next, we need to find AC. AC is a combination of AB and BC, so, we just add them.

3+3=6

<u>AC is 6.</u>

Finally, we need to find DE. We know that AC and CE are congruent because of this sign: ≅. This means they are the same length. We can then know that CE is 6 also. To find DE we need to take the length of CD away from CE. We know that CD is 2, so now, we subtract.]

6-2=4

<u>DE is 4.</u>

<u></u>

I hope this was helpful, keep learning! :D

A car drives at the speed of 90 km/h for 2 hours and 20 minutes? how far does the car drive?
Ksivusya [100]

Answer: 210 km

Step-by-step explanation:

To find the answer, you need to translate the time given into all hours. 20 minutes is 1/3 of an hour so we have 2 and 1/3 hours total. Then all you need to do is multiply that number, 2 and 1/3 hours, by the 90 km/h. You get 210 km total as your answer.

Honda Atlas issued 100,000 shares of stock. In 1990, each share of stock was worth Rs. 152.50. In 1993, each share of the stock
noname [10]

Answer:

Rs.13,130 ,000

Step-by-step explanation:

Lets solve first for year 1990

Value of stock in 1990 = Rs. 152.50

No. of stocks issued in 1990 = 100,000

Total value of these stocks in 1990= Value of stock in 1990* no of stocks issued in 1990  = 152.50*100,000 = Rs. 15,250,000

Let solve first for year 1993

Value of stock in 1993 = Rs. 21.20

No. of stocks   1993 = 100,000

Total value of these stocks in 1993 = Value of stock in 1993* no of stocks issued in 1993  = 21.20*100,000 = Rs. 2,120,000

Decrease in value of stock in 1993 in comparison to 1990 = Total value of the stocks in 1990 -Total value of the stocks in 1993

 =  Rs. 15,250,000 - Rs. 2,120,000

 = Rs.13,130 ,000

Thus, the 100,000 shares worth Rs.13,130 ,000 lesser in 1993 than in 1990.
