Answer:
The number of hot beverages sold were 45 and the number of cold beverages sold were 180.
Step-by-step explanation:
Let the number of cold beverages sold be 
And the number of hot beverages sold be 
According to the question:
c=4
h...
1.5 c + 2 h = Sale of any day
Part1:
For Saturday.
The sale is of 360
then
1.5 c + 2 h = 360
Part 2:
Following the method of substitution.
And plugging the values of c=4 h...in equation where the sales of Saturday is given.
1.5 c + 2
h =360
1.5 4 h + 2 h =360
6 h + 2 h= 360
8 h=360
Dividing both sides with 8.
h=
h=45
Inserting h=45 in c=4 h...
we have c=4 45 = 180
So the number of hot beverages sold were 45 and the number of cold beverages sold were 180.
Just divide 300 by 4 since 25% is 1/4
300/4 = 75
D. 75

Answer:
Step-by-step explanation:
The foci are horizontally aligned.
horizontal ellipse:
(x-h)²/a² + (y-k)²/b² = 1
center (h,k)
vertices (h±a,k)
length of minor axis = 2b
foci (h±c,k), c² = a²-b²
Apply your data and solve for h, k, a, and b.
foci (±3√19, 6)
h = 0
k = 6
Length of minor axis = 2b = 10
b = 5
foci (h±3√19, 6)
c = 3√19
c³ = a² - b²
171 = a² - 25
a² = 196
x²/196 + (y-6)²/25 = 1
x = -2
y = 1
let's multiply second equation by 4 to get a common coefficient of y variable.
16x-8y=-40
add the equations
3×+8y=2
16x-8y=-40
----------------
3x+16x = -38
19x = -38
x = -2
substitute x
3×-2 + 8y = 2
-6 + 8y = 2
8y = 2+6
y = 1
check the answer
-6+8 = 2
-8-2= -20
Answer:
The Exterior Angle of a Triangle Formula states that the measure of an exterior angle is equal to the sum of its remote interior angles. Therefore, r + 58 = 130 which means r = 72°.
