Let x and y be the digits.

x + y = 11
y + x = - 63

Take it from here. We have a system of linear equations in two variables.

Question:

<u><em>"Convert F2 from hexadecimal to binary."</em></u>

Answer:

11110010

Step-by-step explanation:

Hex F2 to decimal explained:

The value of HEX F2 in decimal is 242.

The value of HEX F2 in binary is 11110010.

2 2 X 160 = 2

F 15 X 161 = 240

HEX F2 = 242

<em><u>The binary value is: 11110010</u></em>

A hexadecimal number has base 16 (0,1,2,3,4,5,6,7,8,9 A,B,C,D,E,F).

basic hex to a decimal conversion table

Hex 0 1 2 3 4 5 6 7 8 9 A B C D E F

Decimal 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

A box has a volume of 22 1/2 in³. Find the length of the box!
aliya0001 [1]

Answer:

Length = 2.823 in (to 3 decimal places)  

Step-by-step explanation:

assuming that the box is a cubic box:

volume of box = 22\frac{1}{2} in³ = 22.5 in³

volume = Length × Length × Length = (Length)³

∴ (Length)³ = 22.5

∴ Length = ∛(22.5)

using the calculator punch ∛(22.5), and the answer is:

∴ Length = 2.823 in (to 3 decimal places)

Square GYTD has vertices G(−4,3) , Y(0, 3) , T(0,−1) and D(−4,−1) . ​ Square GYTD ​ is translated 2 units left and 2 units up to
Sliva [168]

we know that

If square GYTD ​ is translated 2 units left and  2 units up to produce square G'Y'T'D'

that means

the rule of transformation is

(x,y)-------> (x-2,y+2)

<u>Find the coordinates of the image</u>

G (-4,3)------->G'(-4-2,3+2)=G'(-6,5)

Y (0,3)------->Y'(0-2,3+2)=Y'(-2,5)

T (0,-1)------->T'(0-2,-1+2)=T'(-2,1)

D (-4,-1)------->D'(-4-2,-1+2)=D'(-6,1)

therefore

<u>the answer is the option</u>

G'(−6, 5), Y'(−2, 5), T'(−2, 1) , and D′(−6, 1)
