Answer:
Step-by-step explanation:
The ratio of smallest sides in the two triangles is ...
smaller / larger = 4/10
To find A and B, we write proportions involving corresponding side lengths.
__
Side A in the smaller triangle is ...
A/15 = 4/10
A = (4/10)(15) = 6
__
The ratio of larger to smaller is the inverse of the above ratio, so ...
B/9 = 10/4
B = (10/4)(9) = 22.5
Two consecutive numbers can be defined as x and y, but a better choice is x and x+1. . The product of the two numbers is: x(x+1). We are told this 41 more than the sum. The sum of the two numbers is: x + (x+1). . So the equation we need to solve is: . x(x+1) = x+(x+1)+41 . x^2 +x = 2x + 42 . subtract 2x from both sides . x^2 +x -2x = 2x-2x + 42 x^2 -x = 42 . subtract 42 from both sides . x^2 -x -42 = 42-42 = 0
Answer:
The cost of per kilogram of salami is = $9.1
Step-by-step explanation:
Given:
Hailey paid $13 for 
kg of sliced salami.
To find cost per kilogram of salami.
Solution:
We will apply unitary method to find per kilogram cost of salami.
If kg of salami costs = $13
Then 1 kg of salami will cost in dollars will be = 
In order to divide by mixed numbers, we will convert mixed numbers to fractions.
⇒ 
⇒ 
In order to divide by fractions we will take reciprocal of divisor and then multiply.
⇒ 
⇒ 
⇒ 
⇒ 
Thus, cost of per kilogram of salami is = $9.1
