Answer:

a) (1000)_2=(8)_{10}

b) DEF+ CBA =1AA9      

Step-by-step explanation:

To find : a) Convert 1000 to hex

b) Add DEF to CBA.

Solution :

a) Convert 1000 to hex

First we convert base 2 into base 10,

i.e. (1000)_2=(1\times 2^3+0\times 2^2+0\times 2^1+0\times 2^0)_{10}

(1000)_2=(8+0+0+0)_{10}

(1000)_2=(8)_{10}

Since, the digit 8 is same in both decimal and hexadecimal.

So, (1000)_2=(8)_{10}

b) Add DEF to CBA.

According to binary system,

A=10 , B=11 , C=12, D=13, E=14, F=15

Adding them with the following steps,

F=15 and A=10

So, 15+10=25

25 in hexadecimal is 19.

We put 9 at first place and forward 1 as a carry.

F=14 and B=11

So, 1+E+B=1+14+11=26

26 in hexadecimal is 1A.

We put A at second place and forward 1 as a carry.

D=13 and C=12

So, 1+D+C=1+13+12=26

26 in hexadecimal is 1A.

We put A at third place and forward 1 as a carry.

 D E F

+C B A

-------------

1 A A 9

Therefore, DEF+ CBA =1AA9

Anastaziya [24]

Answer:

C

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

\frac{BC}{EC} = \frac{AC}{DC}, substituting values

\frac{21}{7} = \frac{24-x}{x} ( cross- multiply )

21x = 7(24 - x) ← distribute

21x = 168 - 7x ( add 7x to both sides )

28x = 168 ( divide both sides by 28 )

x = 6 → C

Substitution property of equality if y=-5 and 7x+y=11, then____. A. 7(-5) + y=11 B.7x-5=11 C.7x+5=11 D.-5+y=11
jolli1 [7]
7x+y=11 where y= -5                                                                                              So, when we substitute y in the equation then,
7x + (-5) = 11 that is 7x - 5 = 11....
So, B. is the right answer.
