Well you could use 15 pennies, 7 dimes, and 3 nickels to make a dollar. It is only 30 coins and it makes a dollar.
Answer:
.
Step-by-step explanation:
Since vertices lie on y-axis. So, it is a vertical parabola of the form
where, (h,k) is center,
is focus and
is vertex.
Center is (0,0). So, h=0 and k=0.
Foci are
. So
.
Vertices are
. So
.
We know that,
Put h=0,k=0, a=8 and b=3 in equation (1).
Therefore, the required equation is
.
Answer:
No solution
Step-by-step explanation:
Create an equation with the values given. Solve like an algebraic question.
11 > 3*x = 75> -1*x
3*x and -1*x should lead to a value greater than 11.
Since there is no value that can be multiplied by a negative and be a positive, besides negative numbers, in which the term of 11>3*x wouldn't be positive, this would have no solution.
No solution.
First find the volume of brick = 18 * 9 * 6 = 972 cm^3
volume of wall
Take note of units in meters. 1m = 100 cm
so we have 4.5 * 100 * 18 * 3.6 * 100 = 2,916,000 cm^3
So we divide the volume of wall by volume of brick to know how many bricks required
2,916,000/972 = 3,000 bricks
Answer:
Alternate interior angles
56 degrees
