Answer: they started at 360 feet
Answer:
See below.
Step-by-step explanation:
(a) Let the cost of the macadamia dough = x and cost of the triple chocolate dough = y.
So we have the following system of equations:
25x + 30y = 221.25 ( Juliens class)
5x + 45y = 191.25 ( Castilejo's class). (Answer).
(b)
Solving:
25x + 30y = 221.25 ......... (1)
5x + 45y = 191.25 ..............(2)
Multiply equation (2) by -5:
-25x - 225y = -956.25 .... (3)
Now add equations (1) and (3):-
-195y = -735
y = $3.77
Substituting in equation (1)
25x + 30(3.77) = 221.25
25x = 221.25 - 113.08 = 108.17
x = $4.33.
Answer The macadamia dough costs $4.33 and the chocolate cost $3.77.
(c) I used the elimination method to solve this because the substitution method would be more awkward - it would involve more calculation and higher numbers.
The volume of the cylinder with a height of 9 cm and a radius of 5 cm is 706.9 cm³, if the radius is doubled, the volume would be 2827.4 cm³ (4 times)
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more number and variables.
Volume of cylinder = π * radius² * height = π * 5² * 9 = 706.9 cm³
If the radius is doubled:
Volume of cylinder = π * (2 * 5)² * 9 = 2827.4 cm³
The volume of the cylinder with a height of 9 cm and a radius of 5 cm is 706.9 cm³, if the radius is doubled, the volume would be 2827.4 cm³ (4 times)

I believe a,d,e,f are yo answers
Answer:
[D] a/b < d
Step-by-step explanation:
a = -1.25
b = 1
c = 0.5
d = 1.25
Now Solve the statement:
a/d > c
substitute
-1.25/1.25 which is -1
-1 > 0.5
Thus, this is false
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
c < ab
substitute
0.5 < (-1.25)(1)
0.5 < -1.25
Thus, this is false.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
a > bc
-1.25 > (1)(0.5)
Hence,
-1.25 > 0.5
Thus, this is false
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
a/b < d
-1.25/1 < 1.25
-1.25 < 1.25
Thus, this is true
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Hence, Answer is [D] a/b < d
