Answer:
B) 81°
Step-by-step explanation:
Given:
From the figure given below,
∠1 = 3x + 18
∠7 = 2x + 39
∠1 and ∠7 are a pair of exterior alternate angles. For two parallel lines l and m, cut by a transversal n, the pair of exterior alternate angles are congruent to each other.
Therefore, the angles 1 and 7 are congruent to each other. This gives,
∠1 ≅ ∠7
Therefore, the value of 'x' is 21.
Now, the measure of angle 7 can be calculated by plugging in the value of 'x' in the expression for angle 7. This gives,
Therefore, the correct option is option (B).
Answer:
The number of servings which can be made by using gallon of milk are <u>128</u>.
Step-by-step explanation:
Given:
A recipe uses 1¼ cups of milk to make 10 servings of pudding.
Now, to find the servings which can be made by using gallon of milk.
Let the number of servings which can be made by using gallon of milk be .
So, we will convert the quantity from fraction into decimal first:
1¼ cups =
Thus, 10 servings need 1.25 cups.
Then, by using proportion we get the quantity of servings:
(1 Gallon = 16 cups.)
⇒
Multiplying both sides by 16 we get:
⇒
⇒
⇒
Therefore, the number of servings which can be made by using gallon of milk are 128.
