I think that the length of DE is 4.  you can add 0.5 to each side of BC in order to find the length of EF since EF starts 0.5 before BC does and therefore also ends 0.5 after BC since the circle is symmetrical.

If ef bisects angle ceb,angle cef=7x+31 and angle feb=10x-3
Nastasia [14]

Given : Angle  < CEB is bisected by EF.

< CEF = 7x +31.

< FEB = 10x-3.

We need to find the values of x and measure of < FEB, < CEF  and < CEB.

Solution: Angle  < CEB is bisected into two angles < FEB and < CEF.

Therefore,   < FEB = < CEF.

Substituting the values of < FEB and < CEF, we get

10x -3 = 7x +31

Adding 3 on both sides, we get

10x -3+3 = 7x +31+3.

10x = 7x + 34

Subtracting 7x from both sides, we get

10x-7x = 7x-7x +34.

3x = 34.

Dividing both sides by 3, we get

x= 11.33.

Plugging value of x=11.33 in < CEF = 7x +31.

We get

< CEF = 7(11.33) +31 =  79.33+31 = 110.33.

< FEB  = < CEF =  110.33 approximately

< CEB = < FEB +  < CEF  = 110.33 +110.33 = 220.66 approximately

Convert the following metric units of weight. a. 40 centigrams to grams b. 53 milligrams to grams c. 0.54 grams to decigrams d.
liubo4ka [24]

Answer:

a) 0.4 grams

b) 0.053 grams

c) 5.4 decigrams

d) 2300 milligrams

Step-by-step explanation:

a)

To convert centigrams to grams you have to divide by 100.

40 centigrams = \frac{40}{100} grams

                                        =0.4 grams

b)

To convert milligrams to grams you have to divide by 1000.

53 milligrams = \frac{53}{1000} grams

                                        =0.053 grams

c)

To convert grams to decigrams you have to multiply by 10.

0.54 grams = 0.54*10 decigrams

                                        =5.4 decigrams

d)

To convert grams to milligrams you have to multiply by 1000.

2.3 grams = 2.3*1000 milligrams

                                        =2300 milligrams

Find the product. x^5 x^4 x^3
Brut [27]
If you would like to solve x^5 * x^4 * x^3, you can do this using the following steps:

<span>x^5 * x^4 * x^3 = x^(5 + 4 + 3) = x^12
</span>
The correct result would be x^12.
