i 7/3, -i 7/3.
Answer:
Mr K purchased 6 chicken sandwiches and 6 pizza slices.
Step-by-step explanation:
Let Mr. K purchased number of chicken sandwiches = x
and number of pizza slices = y
Since total number of dancers = 12
then the equation will be
x + y = 12 --------(1)
Mr K. spent total amount = $72
Therefore, equation to purchase x sandwiches, y pizza slices and 12 drinks will be
6x + 3y + 1.5×(12) = 72
6x + 3y + 18 = 72
6x + 3y = 54
2x + y = 18 -------(2)
We subtract equation (1) from (2)
(2x + y) - (x + y) = 18 - 12
x = 6
from equation (1)
6 + y = 12
y = 6
Therefore, Mr K purchase 6 chicken sandwiches, 6 pizza slices.
Because the gravity is making him fall so it will splash them
Answer:
3√2
Step-by-step explanation:
The hypotenuse of an isosceles right triangle is √2 times the side length.
x = 3√2
_____
All these triangles are similar, so the ratio of hypotenuse to leg is the same for all.
hypotenuse/leg = x/3 = (3+3)/x
x² = 3·6 = 3²·2 . . . . cross multiply (identify square factors)
x = 3√2 . . . . . take the square root
Answer:
x = 5/16
Step-by-step explanation:
