Answer: x(1-0.33) or 0.67 x

Step-by-step explanation:

The old soup recipe contained sodium per serving = x mg

According to the question,

The new soup recipe contains 33% less sodium per serving than the old soup recipe.

That is, the Sodium per serving in the new soup = the Sodium per serving in the new soup - 33% of the Sodium per serving in the new soup

= x - 33% of x

= x - 0.33 x      ( since 1% = 0.01 ⇒ 33 % = 0.33 )

= x(1-0.33)

= x(0.67)

Sara had 94 dollars to spend on 8 books. After buying them she had 14 dollars. How much did each book cost
cestrela7 [59]

Answer: $10

Step-by-step explanation:

Let's analize the information given: We know that  she had $94 to spend on 8 books and after buying these books she had $14. So, we need to calculate the amount of money she spent. Subtract $94 and $14:

Total\ spent=\$94-\$14\\Total\ spent=\$80

Then, to calculate the cost of each book, we need to divide the "Total spent" by 8:

cost\ of\ each\ book=\frac{Total\ spent}{8}\\\\cost\ of\ each\ book=\frac{\$80}{8}\\\\cost\ of\ each\ book=\$10

A rectangular garden must have a perimeter of 150 feet and an area of at least 1200 square feet. Describe the possible lengths o
kipiarov [429]

Answer: 51.86 and 23.14

Step-by-step explanation:

The rectangular garden must have a perimeter of 150 feet

Perimeter of rectangular garden =

2l + 2w=150 -----------1

The rectangular garden must have a perimeter of 150 feet and an area of at least 1200 square feet.

Area of rectangular garden =

l×w= 1200 feet^2 -----------2

From equation 2, l=1200/w

Put l=1200/w in equation 1

2× 1200/w + 2w = 150

(2400/w) +2w = 150

(2400+2w^2)/w =150

2400+2w^2= 150w

2w^2- 150w+2400=0

Using the general formula

w = [-b+-√(b^2-4ac)]/2a

a = 2, b =-150, c=2400

w =[--150+/-√(-150^2-4×2×2400)]/2×2

=[150+/-√(22500-19200)]/4

=[150+/-√3300)]/4

=(150+57.45)/4 or (150-57.45)/4

w= 207.45/4 or 92.55/4

w= 51.86 or w= 23.14

l = 1200/51.86 or l= 1200/23.14

l = 23.14. or l= 51.86

For an area of at least 1200ft^2

The dimensions are 51.86 and 23.14
