Gum is on sale. You can get 50 packages for $6.99 at the Candy Store, 40 pieces for $5.75 at Sweet Treats or 25 pieces for $4.25 at Chew-chew's. Where will you buy your gum for the best buy?
Answers
Answer:
The Candy Store
Step-by-step explanation:
In order to find the best buy, we have to find the unit price for each store. The first store we will look at is the Candy Store. To find unit prices, we must divide the price by the number of merchandise for sale, as shown here:
6.99 / 50 = 0.1398
This means each piece of gum costs a little less than 14 cents.
Moving on to Sweet Treats:
5.75 / 40 = 0.14375
Each piece of gum at this store costs a little more than 14 cents.
Last but not least, Chew-Chew's:
4.25 / 25 = 0.17
Each piece of gum here costs 17 cents.
Now, to determine which price is better, we have to go with the lowest unit price, which would be at the first shop, the Candy Store, which is your answer.
Hope this helps :)

Miko walked a distance of 1.60 km in 30 min. Find her average speed in m/s.
Answers
Miko walked a distance of 1.60 km in 30 min. Find her average speed in m/s.
Distance travelled = 1.6km = 1600m
Time taken = 30min = 30*60 = 1800s.
speed = distance/time = 1600/1800 = 0.89m/s

Find all numbers such that 16 plus 3 times the number is no more than 46. A. x > 11 B. x 11 D. x < 10
Answers
Answer:
D. x ≤ 10 (if you wrote the wrong sign)
or No answer
Step-by-step explanation:
x - the number
3x - three times the number
no more than 46 means ≤46
16 + 3x ≤ 46
3x ≤ 46 - 16
3x ≤ 30
x ≤ 30:3
x ≤ 10
The numbers are x < 10
What is inequality?A statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions.
Given:
16 plus 3 times the number is no more than 46.
let the number be x
then, three times the number be 3x
Lastly, not more than 46.
So,
16 + 3x ≤ 46
3x ≤ 46 - 16
3x ≤ 30
x ≤ 30/3
x ≤ 10
Hence, the number should be x < 10.

OK, I cut a cake vertically to make 2 congruent parts. a) Find the perimeter and area of the cross section formed by the cut. Write your answer as a decimal. The perimeter is __ inches and the area is __ square inches. b) Find the surface area of the cake that is not frosted before the cut. Round your answer to the nearest hundredth. The surface area is about __square inches.
Answers
Answer:
The perimeter is 36.5 inches.
The area is 59.5 square inches.
The surface area is about 153.94 square inches.
Step-by-step explanation:
From the figure it is clear that,
Radius of cake = 7 in
Diameter of cake = 14 in
Height = 4.25 in
We need cut the cake vertically along its diameter to make 2 congruent parts.
So, cross section is a rectangle of length 4.25 in and width 14 in.
Perimeter of rectangle is
[tex]Perimeter=2(length+width)[/tex]
[tex]Perimeter=2(4.25+14)[/tex]
[tex]Perimeter=2(18.25)[/tex]
[tex]Perimeter=36.5[/tex]
The perimeter is 36.5 inches.
Area of rectangle is
[tex]Area=lengt\times width[/tex]
[tex]Area=4.25\times 14[/tex]
[tex]Area=59.5[/tex]
The area is 59.5 square inches.
We need to find the surface area of the cake that is not frosted before the cut. It means the area of base.
Area of circle = [tex]\pi r^2[/tex]
where, r is radius.
Area of circular base = [tex]\pi (7)^2[/tex]
[tex]=49\pi [/tex]
[tex]=153.93804[/tex]
[tex]\approx 153.94[/tex]
Therefore, the surface area is about 153.94 square inches.
