Answer:
Perimeter:
Area:
Step-by-step explanation:
I will assume the question asks for perimeter and area of the rectangle with given dimensions.
The height is "4"
The width (assuming) is ""
First, the perimeter:
Perimeter is sum of all 4 sides of a rectangle, so we have 2 widths and 2 lengths, we sum them up:
Now, the area:
Area is the height times width, so it will be:
Answer:
255
Step-by-step explanation:
total cost paid = fixed cost + total variable cost
total variable cost = distance travelled x variable cost per unit
two equations can be derived from the question
a + 10b = 105 equation 1
a + 15b = 155 equation 2
a = fixed cost
b = variable cost per unit
Subtract equation 1 from 2
5b = 50
b = 10
Substitute for b in equation 1
a + 10(10) = 105
a = 105 - 100 = 5
a = 5
cost of travelling a distance of 25km
5 + 10(25) = 255
Answer:
9/16
Step-by-step explanation:
Basically prime numbers are those numbers whose only factors are 1 and themselves (ie. 3's only factors are 1 and 3, 5's only factor's are 1 and 5). Between 40 and 60 there are the following prime numbers:
