Grace opens a lemonade stand in her neighborhood to earn money. For each cup of lemonade she sells, Grace earns $0.50 profit. Considering that it cost her $6 in start-up costs, Grace graphed her potential profits, where x represents the number of cups of lemonade she sells and y represents the amount of profit earned in dollars. However, Grace made a mistake with her graph. Her y-intercept was incorrectly drawn. At what value should the graph have crossed the y-axis?

When I round 6396 to 3 significant figures, I get 6400. I was double checking my work and used scientific notation for 6400, which is 6.4*10³, but when I counted the significant figures in scientific notation, I only get 2, which are 6 and 4, but there were supposed to be 3. Anyone can help to explain?
Answers
This is one slight annoyance when it comes to sig figs, in my opinion anyway. You did the steps correct. The 639 bumps up to 640, so 6396 rounds to 6400 when rounding to 3 sig figs.
Normally the trailing zeros, ie zeros on the right, are not significant. So 6400 shows only 2 sig figs. What we need to do is draw a horizontal line over the first zero to show that it is significant (while the other zero is not significant)
So you'll write it like this [tex]64\overline{0}0[/tex]
This notation can be problematic when it comes to decimals because it could be easily mixed up with the repeating decimal notation.
When you convert [tex]64\overline{0}0[/tex] to scientific notation, you would get [tex]6.40 \times 10^3[/tex].
In short: [tex]64\overline{0}0 = 6.40 \times 10^3[/tex]
Here the zero is significant because the zero is present in the scientific notation result. Writing [tex]6.4 \times 10^3[/tex] shows 2 sig figs while [tex]6.40 \times 10^3[/tex] has 3 sig figs.
It's similar to how the number [tex]5.7[/tex] has 2 sig figs while [tex]5.70[/tex] has 3 sig figs. While the zero is trailing, having it after a decimal point indicates to the reader that you achieved this level of accuracy.

Clare mixes

cups of water with
1/3
cup of orange juice concentrate.
—————————
How much water would she use for one cup of concentrate? (use a decimal)
—————————
How much water would she use for 10 cups of concentrate? (use a decimal)
Answers
Answer:
1. 1 cup of concentrate would use 7.5 cups of water.
2. 10 cups of concentrate would use 75 cups of water.
Step-by-step explanation:
Because 1/3 cup of concentrate is mixed with 2 1/2 cups of water, to find how much water one cup of concentrate would use, you would have to multiply both 1/3 and 2 1/2 (2.5) by 3. Then, you get 1 cup of concentrate equals 7 1/2 (7.5).
To find the answer to the next question, simply multiply by 10.

You want to measure the length of a ribbon in inches. You only have a centimeter ruler. The length of the ribbon is 15 cm. Is the ribbon longer or shorter than 15 inches? How many inches long is it?
Answers
Answer:
Shorter than 15IN, 5.9 or 6 inches
Hope this helps:)
Step-by-step explanation:
The ribbon is shorter than 15 inches, and its length is approximately 5.91 inches.
Given that a ribbon has a length of 15 cm, we need to calculate the length in inches,
To determine the length of the ribbon in inches, we need to convert the length from centimeters to inches.
To convert centimeters to inches, we can use the conversion factor 1 inch = 2.54 centimeters.
The length of the ribbon is 15 centimeters. To convert this to inches, we divide 15 by 2.54:
15 cm / 2.54 cm/inch = 5.91 inches (rounded to two decimal places).
So, the ribbon is shorter than 15 inches.
The ribbon is approximately 5.91 inches long.

On the map below, city p and city q are 5.5 centimeters (cm) apart. What is the actual distance between city p and city q? 2cm= 35 miles
Answers
Answer:
96.25
Step-by-step explanation:
5.5/2=2.75
2.75x35=96.25
Meaning ONE centimeter is 35/2, or, 17.5 miles of actual distance
And half, or 0.5 of a centimeter is 17.5/2 or 35/4, which is 8.75 miles
5 centimeters is 2 + 2 + 1 + 0.5
(35 miles) plus (35 miles) plus (17.5 miles) plus (8.75 miles) which would add up to be 96.25 miles

on monday 72% of the class ordered lunch. which fraction shows the part of the class that ordered lunch?
Answers
The fraction showing the part of the class that ordered lunch is 18/25
What are fractions?A fraction represents equal parts of a whole, by dividing it up into equal partitions.
Each fraction has a numerator and denominator. The denominator represents the total number of parts the whole has been divided into.
Given that, on Monday 72% of the class ordered lunch we need to find the fraction showing the part of the class that ordered lunch,
So, we know that, 72% = 72 / 100
= 36/50 = 18/25
Hence, the fraction showing the part of the class that ordered lunch is 18/25

Mrs. Taylor is knitting socks. it takes her 1/4 hour to knit one pair of socks. She has a meeting to go to in 3 1/2 hours.
How many pairs of socks can she knit before her meeting?
Answers
Answer:
14 socks.
Step-by-step explanation:
3 1/2 / 1/4

= 7/2 * 4
= 28/2
= 14 socks.
Answer:
14
Step-by-step explanation:
Mrs. taylor can knit 4 socks in an hour, so if she has to go to her meeting in 3 1/2 hours, she should be able to knit 14 pairs of socks. The reason for this is in 3 hours she can knit 12 socks because 4 times 3 is 12. Then, in half an hour she can knit 2 socks because she can knit one pair in 1/4 so in 1/2 it would be 2.

The water park is a popular field trip destination. This year the senior class at high school a and high school b both planned trips there. The senior class at high school a rented filled 4 vans and 14 buses with 742 students. High school b rented and filled 4 vans and 6 buses with 350 students. Each van and each bus carried the same number of students. Find the number of students in each van and in each bus.
Answers
x = buses
y = vans
our equations will look something like this :
4x + 14y = 742 &’
4x + 6y = 350
let’s solve for y first . we need to cancel out our x’s so we turn on of them into a negative and since both of them have the same common factor we don’t need to find it . let’s multiply the bottom equation by ( -1 )
here’s what our new equations look like :
4x + 14y = 742
-4x - 6y = -350
now that our x’s are cancelled out we add our y’s and our totals :
14y + ( -6y ) = 8y
742 + ( -350 ) = 392
we want y alone so we divide :
392/8 = 49
y = 49
now we can substitute 49 for y :
4x + 14 ( 49 ) = 742
4x + 6 ( 49 ) = 350
we can multiply those numbers together :
4x + 686 = 742
4x + 294 = 350
now we add downward :
8x + 980 = 1,092
we need x alone so we subtract 980 from both sides :
8x = 112
divide by 8 :
x = 14
now , we can substitute 14 for x and 49 for y to check our work :
4 ( 14 ) + 14 ( 49 ) = 742
742 = 742 ✅
4 ( 14 ) + 6 ( 49 ) = 350
350 = 350 ✅
