Answer:
84
Step-by-step explanation:
because the top and bottom lines are parallel, we can conclude that the 2 triangles (top and bottom) are similar triangles. This means the sides lengths of smaller triangle is proportional to the respective sides on the larger triangle. With this, we can form the following equation:
x/48 = 21/12 (multiply both sides by 48)
x = (21/12)· 48
x = 21 ·4
x = 84
Answer:
No
Step-by-step explanation:
Rational numbers are those that can be represented in a fraction form.
2.12359.... cannot be represented in a fraction form.
So, it is NOT a rational number
Answer:
6.18
Step-by-step explanation:
yes
2 consecutive numbers....x and x + 1
x(x + 1) = 182
x^2 + x = 182
x^2 + x - 182 = 0
(x - 13)(x + 14) = 0
x - 13 = 0
x = 13
x + 14 = 0
x = -14....not this one because it is negative
x + 1 = 13 + 1 = 14
ur 2 numbers are : 13 and 14
You just multiply the sides.
Firstly, it's easier if you convert both measurements to inches.
so you'd do 6 x 12 = 72 , 72 + 5 = 77 inches
and 4 x 12 = 48 , 48 + 3 = 51 inches.
Then you multiply the sides, so:
77 x 51 = 3927 inches
then you divide by 12 to get how many feet and inches it is
3927/12 = 327 feet and 4 inches
