An Italian restaurant buys 15 pounds of onions every 2 weeks. how many bags of onions will the restaurant buy in 7 weeks?

Answers

Since it is 7 weeks and they order 15 pounds every two weeks they will order 3 times. 15 times 3 is 45. Your answer is 3 bags

2 goes into the 7 weeks 3 times with a remainder of a week until they buy another 15 pounds of onions. So 15 x 3 = 45 pounds. They’ll have 45 pounds of onions in 7 weeks as on the 8th week they’ll buy another 15 pounds but the question only wants to know by the 7th week.

The area of a rectangular trampoline is 135 ft. The length of the trampoline is 6 ft
greater than the width of the trampoline. This situation can be represented by the
equation w2 +6w
135 = 0.
What is the width of the trampoline, in feet?
5 feet
15 feet
6 feet
9 feet

Answers

The width of the given trampoline is 9 feet, and which area is 135 square feet.

What is the area of the rectangle?

The area of a rectangle is defined as the product of the length and width.

The equation w² +6w -135 = 0 can be factored as (w+15)(w-9) = 0.

Therefore, the solutions for w are w = -15 or w=9.

Since the width of the trampoline cannot be negative, we can conclude that the width of the trampoline is 9 feet.

To confirm this, we can calculate the length of the trampoline using the given information that the length is 6 feet greater than the width:

length = width + 6 = 9 + 6 = 15 feet

Then we can verify that the area is indeed 135 ft²:

area = length x width = 15 x 9 = 135 ft²

Therefore, the width of the trampoline is 9 feet.

Answer:

y ≈ 5.2

Step-by-step explanation:

∠ F = 180° - (42 + 48)° ← sum of angles in a triangle

∠ F = 180° - 90° = 90°

Thus Δ DEF is right at F

Using the sine ratio in the right triangle

sin48° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{DF}{DE}[/tex] = [tex]\frac{y}{7}[/tex] ( multiply both sides by 7 )

7 × sin48° = y , then

y ≈ 5.2 ( to the nearest tenth )
