Answer:
C: x = 5 and y = (5√3)/2
Step-by-step explanation:
Looking at the triangle, we can use trigonometric ratios to find x and y since it's a right angled triangle.
Thus;
(5/2)/x = sin 30
x = (5/2)/½
x = 5
Similarly, (5/2)/y = tan 30
tan 30 in surd form is 1/√3
Thus;
(5/2)/y = 1/√3
y = 5/2 × √3
y = (5√3)/2
Answer:
c = $30 + $0.75p
Step-by-step explanation:
total cost = total fixed cost + total variable cost
total fixed cost = $30
Fixed costs are costs that do not vary with output.
total variable cost = variable cost per unit x total unit
p x 0.75
Variable costs are costs that vary with production
Answer:
Step-by-step explanation:
Since the ladybug is 
far from each edge of the rectangle, it follows that the length of the new rectangle is 
and the width is 
.
Recall a formula for the area of a rectangle: 
, where 
is a length and 
is a width of the rectangle.
Substitute 
and 
into the formula:
Multiply the numbers:
Therefore, the required area is equal to .
One way is brute force or experiment
20*10=200
20*100=2000
20*50=1000, that is the first 4 digit number
now add 5
1005
the answer is 1005
