Answer:
4 and 10
Step-by-step explanation:
To solve this problem, we need to find all the numbers between 1 and 13 that have a sum of 14. The list is shown below:
1 + 13, 2 + 12, 3 + 11, 4 + 10, 5 + 9, 6 + 8, 7 + 7
Now we must figure out which set of numbers include one number that is 2/5 of the value of the other. We can do that by turning the sets of numbers into fractions as shown below:
(answer)
the equation that represents the cost is a lineal and it is ,as you can see , it is a function with positive slope, it means that as the pounds are heavier, the shipping cost will be higher, the shipping cost is from three dollars onwards, as you can see in the graph, as there are no negative weights, the values of x are taken to from zero onwards
<u>Given</u>:
The triangle DEF is a right triangle.
The length of EF is 12 units.
The length of DE is y units.
The measure of angle D is 25°
We need to determine the value of y.
<u>Value of the variable:</u>
The value of the variable y can be determined using the trigonometric ratio.
Thus, we have;
Substituting , EF = 12 and DE = y, we get;
Simplifying, we get;
Rounding off to the nearest tenth, we get;
Thus, the length of the variable y is 20.8 units.
