Decimal form: 18.8
Mixed number: -18 4/5
Exact form: -94/5
Answer:
7x+ 5y <= 10
Step-by-step explanation:
As the x represents the number of pounds of almonds and the price of the almonds is $7/lb, we need to look for an inequality where the x is multiplied by $7 and the same with the y and $5.
It's useless to multiply the x by $5 or the y by $7 because we are mixing the prices of the nuts.
On the other hand, we don't want to spend more than 10. That means we can spend 10 or less.
Therefore, the inequality we can use to find how much of each type of nut we can buy without spending more than $10 is
7x+ 5y <= 10

Step-by-step explanation:
So sin in math means:
In a right angled triangle, the sine of an angle is: The length of the side opposite the angle divided by the length of the hypotenuse. The abbreviation is sin.
Con in math means:
In a right angled triangle, the cosine of an angle is: The length of the adjacent side divided by the length of the hypotenuse. The abbreviation is cos. cos(θ) = adjacent / hypotenuse.
in this case it has to be a sin. So its either A, or B.

Answer:
Step-by-step explanation:
Remark
- x is opposite the 90 degree angle. It is the hypotenuse.
- 15 is opposite the 66 degree angle. It is the side opposite.
- The side opposite and the hypotenuse define the sin(theta).
Formula
sin(theta) = side opposite / hypotenuse
Givens
Theta = 66 degrees
Hypotenuse = x
Side Opposite = 15
Solution
- Sin(theta) = 15 / x Multiply both sides by x
- x*sin(theta) = 15 Divide by Sin(theta)
- x = 15/sin(theta)
- x = 15 / sin(66)
- sin(66) = 0.9135
- x = 15/ 0.9135
- x = 16.42
