II 24x2 =52
in What base at the
number?​

Answers

Answer: WE are multiplying in base 6

Step-by-step explanation:

24 x 2 = 52 can only be in base 6

because    2¹  4            2 x 4 = 8/6 = 1 rem 2.                        

              x        2₆           2 x 2 + 1= 5

              5      2          

From the above , we can see theta 24 x 2 = 52 can only  be in base 6.

Because only 2 x 4 = 12 can be possible in base 6.

Counting in base 6  gives us that after 5, the next number is 10. Just like counting in the common base 10, which after 9 we get 1 0

in Base 10--- 1, 2,3, 4,5, 6,7,8,9,10

in Base 6---  1, 2, 3,4,5,10,11,12, 13,14  and so o

The required base of the isosceles triangle is given as 38 feet.

What is the isosceles triangle?

A triangle with two sides and two congruent angles is called an isosceles triangle.

here,

For a given isosceles triangle,
side/base = 2 / 7
side = 2/7 base = 7 /2 sides

According to the question,
The perimeter of the triangle is 304 feet,
2 side + base = 304
2 [7/2 base] + base = 304
8 base = 304
base= 304 / 8
base = 38 feet

Thus, the required base of the isosceles triangle is given as 38 feet.

Step-by-step explanation:

Since both triangles are similar, therefore,

[tex] \frac{UV}{PQ} = \frac{VW}{QR} [/tex]

[tex] \frac{77}{66} = \frac{63}{x} [/tex]

[tex] \frac{7}{6} = \frac{63}{x} [/tex]

Cross multiply

[tex] 7*x = 63*6 [/tex]

Direct answer :

Width of the enlarged photograph = 14 cm

Steps to derive the correct answer :

Length of a small photograph = 6 cm

Width of a small photograph = 4 cm

Length of the photograph when enlarged = 21 cm

Let the width of the photograph when enlarged be x.

Which means :

[tex] = \tt 4 : 6 : : x : 21[/tex]

[tex] =\tt \frac{4}{6} = \frac{x}{21} [/tex]

[tex] =\tt 4 \times 21 = 6 \times x[/tex]

[tex] =\tt 84 = 6x[/tex]

[tex] =\tt x = \frac{84}{6} [/tex]

[tex] =\tt x = 14[/tex]

Thus, the value of x = 14

Therefore, the width of the enlarged photograph = 14 cm

Well the difference between each number is multiplied by -3. So you could do y= -3x + 4. X would start at 0 so x= 0 which plugged in would be 4 which is the first answer. For the second number x=1 when plugged in you get y as -12 which is the second number and so on.
