Answer:
x = 8
Step-by-step explanation:
Using the sine or cosine ratio in the right triangle and the exact value
sin30° = 
, then
sin30° = 
= 
= ( cross- multiply )
x = 8
Answer:
259/30 or 8 19/30 depending on what format your teacher wants the answer
Step-by-step explanation:
First we can turn both mixed fractions into improper fractions and to do that we multiply the whole number by the denominator and that add that to the top number. So for 3 4/5 we would multiply 3 and 5 and than add 4 getting us to 19/5 doing the same to 4 5/6 gets us to 29/6. Now in order to add fractions we need to get a common denominator. The least common multiple of 5 and 6 is 30 so we will multiply each fraction by whatever number will give us 30 in the denomiator. for 19/5 that number is 6 so our new fraction is 114/30 and for 29/6 that number is 5 so our new number is 145/30. Now we just add the numerators and simplify. 114/30+145/30=259/30

Step-by-step explanation:
"Any strategy" includes letting a calculator solve it.
We find the tea costs $0.80 and the gum $0.45, so the price of Rocco's purchase will be $4.90.
Answer:
15 people will be served before the cooler would be empty
Step-by-step explanation:
Here, we want to know the number of persons that could be served if the total amount of water available is 7.5L and each serving is 500 milliliters
What we are going to do here is to divide the total amount of water available by the number of individual servings
Mathematically, that would be;
7.5L / 500 milliliters
So we need to convert 7.5L to milliliters
Since 1000 mL = 1L ; 7.5 L = 7.5 * 1000 = 7500 mL
So the number of people served will be;
7500/500 = 15 people
