<u>Answer:</u>
Ella will need 6 lemons for 4 times the recipe
<u>Explanation:</u>
Given Ella used ¾ of a bag of lemon to make ½ liters of lemonade
Therefore, we can form an equation as:
¾ bag lemons = ½ liter lemonade
According to question,
Ella recipe is for 1 liter of lemonade
Lemons required for ½ liter lemonade = bag
Lemons required for 1 liter lemonade = = 3/2 bags
To make 4 times the recipe, she will require,
She will need 6 lemons for 4 times the recipe
Answer:
D) 57.5°
Step-by-step explanation:
As the question is not complete. So, let's suppose it is a right angle triangle then, we can apply Pythagoras theorem to calculate the hypotenuse or the third side.
Pythagoras Theorem = =
a = 7 and b = 11
= 49
= 121
Plugging in the values, we will get:
= 49 + 121
= 170
c =
To calculate the unknown angle B, we can use law of sine.
Law of sine = =
=
So,
=
=
Sin90 = 1
sinB =
B = (
)
B = 57.5°
Answer:
Arithmetic sequence states that a sequence of numbers such that the difference between the consecutive terms is constant.
it is given by: where a is the first term , n is the number of term and d is the common difference.
Given the series:
here, Common difference(d) = 5
First term(a) = 49
by definition we have;
For nth term
= 5n + 44
To write the series using summation notation for 14 terms
Summation symbol
The series for 14th terms is given by;
