What is Unitary Method?
The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Nina earns $15 for each yard she mows.
She wants to buy a dress that is $109.
so, she needs to mow
= 109/ 15
= 7.266 yards
Hence, Nina needs to mow 7.266 yards of lawn.

Im supposed to simply this into a rational number how do i do this?
Monica’s school band held a car wash to raise money for a trip to a parade in New York City. After washing 125 cars, they made $775 from a combination of $5.00 quick washes and $8.00 premium washes. Let x represent the number of quick washes and let y represent the number of premium washes. Which system of linear equations represents the situation? 5x + 8y = 775 and x + y =125 5x – 8y = 125 and x + y = 775 5x + 8y = 775 and x – y = 125 5x – 8y = 125 and x – y = 775

B. 1,130.40 cubic feet
Step-by-step explanation:
Volume of a cylinder is
V = pi * r^2h
We know r=6 and h =10 and use 3.14 for pi
V = 3.14 * 6^2 *10
V =3.14*36*10
V = 1130.4 ft^3

Answer:
(2, - 5)
Explanation:
The line y = -1 is horizontal: parallel to the y-axis.
The point B (2,3) is above the line y = - 1 at a distance equal to the y-coordinate of B (y = 3) less - 1:
Δy = 3 - ( - 1) = 4
When the point B (2,3) is reflected over the line y = -1, the x-coordinate does not change. The image will be 4 units down the line y = -1, thus the y-coordinate will be - 1 - 4 = - 5.
Hence, the coordinates of the vertex B' are x = 2, y = - 5: (2, - 5).

y +1 = 3/5(x+3)
y + 1 = 3/5x + 9/5
y =3/5x + 9/5 - 1
y = 3/5x + 9/5 - 5/5
y = 3/5x + 4/5
