(a)
10 miles ーー> 65 minutes
1 mile ーー> 65 minutes ÷ 10 = 6.5 minutes
∴ Chau takes 6.5 minutes to run 1 mile.
(b)
16 pound ーー> $9
1 pound ーー> $9 ÷ 16 = $0.5625
∴ Diane paid $0.5625 per pound of rice.
Answer:
The 16-oz bottle of parmesan cheese is the better buy.
Step-by-step explanation:
Even though 8-oz is half the amount of 16-oz, that doesn't mean it's cheaper. Let's find the amount of and 8-oz bottle when a 16-oz bottle is $5.78:
16-oz bottle of parmesan cheese = $5.78
A price of an 8-oz bottle when 16-oz is divided by 2:
16 ÷ 5.78 = $2.76
The original price of the 8-oz bottle should've been $2.76 but it's more expensive due to VAT.
So the 8-oz bottle is more expensive, therefore the 16-oz bottle is the better buy!
Answer:
y = 9x - 40
Step-by-step explanation:
Using the point-slope equation of a straight line is the fastest approach here, since we already have the slope and a point:
y - k = m(x - h) becomes y - 5 = -9(x + 5)
Solving for y, this becomes y = 9x + 5 - 45, or y = 9x - 40
Answer:
Step-by-step explanation:
add the whole numbers
combine the fractions
LCM is 35 because 7 * 5 =35
change the improper fraction into mixed number
Answer:
Length = x feet = 95 feet
Step-by-step explanation:
The labeled triangles are not included in the question, therefore, I will calculate the length of the rectangular space for Kelly's dog
Perimeter of a rectangle = 2(length + width)
Perimeter of a rectangle = 236 feet
Width = 23 feet
Length = x feet
Perimeter of a rectangle = 2(length + width)
236 = 2(x + 23)
236 = 2x + 46
236 - 46 = 2x
190 = 2x
x = 190/2
x = 95 feet
Length = x feet = 95 feet
