Amber completed a 25-kilometer road race in 3 hours. She ran at the same speed and covered the same distance each hour. Between which 2 whole numbers does the distance she ran each hour lie? Draw a visual model to find the distance she ran each hour.

You don’t have to do the last part but it’d be great if you did

Answers

To answer this question, you will find the number of kilometers she ran per hour. This is called the unit rate. To get the unit rate, you will divide the number of kilometers by the number of hours, so 25/3. The answer is 8 1/3 kilometers per hour. This number falls between the whole numbers 8 and 9. I will describe to you how to create a visual model to show this. If you draw a long bar and break it into 25 equal sections. Take 24 of these groups and circle 3 groups of 8 to show the 8 km. Take the last group and break it into 3 equal sections as well (creating groups the size of 1/3). One of these goes with the group of 8 you got when you broke the whole sections into groups of three creating the mixed number 8 1/3 kilometers. This shows you modeling the 25 km broken into 3 equal sized groups (which is division).

The distance she ran each hour is between 8 and 9

How to determine the whole numbers?

The distance is given as:

Distance = 25 km

The time is given as:

Time = 3 hours

The speed is then calculated as:

Speed = Distance/Time

So, we have:

Speed = 25km/3 hours

Divide

Speed = 8.33 km/hr

8.33 is between 8 and 9

Hence, the distance she ran each hour is between 8 and 9

Alcia received a $75 gift certificate for her birthday. She went to a boutique to buy some T- shirts at $7 each and some socks for $2.50 a pair. If T represents the number of T-Shirts, and S represents the number of pairs of socks she bought, write an inequality that would determine the number of T-shirts and pairs of socks she could buy. HURRY PLEASE

Answers

So, Since she has $75 total, that means she can buy 8 t-shirts and 7 socks with $1.50 left

T represents the number of T-Shirts

S represents the number of pairs of socks she bought

Each T-shirt cost $7, so 'T' T-Shirts will cost 7T

Each Pairs of socks cost $2.5, so 'S' pair of socks cost 2.5S

[tex] Total \; cost\; =\; T-shirts \; cost \; +\; Pair \; of \; socks\; cost \\ \\ Total \; Cost \; =\; 7T+2.5S\\ \\ [/tex]

Total cost should be less than or equal to 75 dollars.

Conclusion:

The inequality that would determine the number of T-shirts and pairs of socks she could buy is given below:

[tex] 7T+2.5S\leq 75 [/tex]

Gloria Trench checked her gas mileage and found that she had used 16.6 gal of gas to travel 372 mi. At this rate, how many gallons will she use to travel from San Francisco to Washington, D.C., a distance of 2,850?

Answers

Final answer:

Using the rate of miles per gallon for Gloria's car, we calculated that she will need approximately 127.2 gallons of gas to travel from San Francisco to Washington, D.C.

Explanation:

To solve this problem, we'll use the principle of ratios.

First, we find the rate of miles per gallon for Gloria's car by dividing the distance travelled by the gallons used:

372 miles ÷ 16.6 gallons = 22.4 miles per gallon

With this information, we can calculate how many gallons Gloria will need to travel from San Francisco to Washington D.C., which is a distance of 2850 miles:

2850 miles ÷ 22.4 miles per gallon = 127.2 gallons

So, Gloria will use approximately 127.2 gallons of gas to travel from San Francisco to Washington, D.C., at her current rate.

Jose decided to walk the 9 3/10 mi from his house to the beach. in the first hour he walked 3 4/5 mi. in the second hour he walked 2 9/10 mi. how much farther did he have to go?

Answers

9 3/10, 3 8/10, 2 9/10

8/10 + 9/10 = 1 7/10

3+2+1 7/10 = 6 7/10

9 3/10 - 6 7/10 = 2 6/10

Ok so, first we have to turn these into improper fractions

9 3/10= 93/10
3 4/5= 19/5
2 9/10= 29/10

Ok so 19/5 + 29/10 is 67/10

67/10 - 93/10= 13/5.

13/5 or 2 3/5 is the answer, good luck, hope this helped, and STAY SMART! =p

A cylinder has a volume of 136 cubic centimeters. What is the volume of a cone with the same height and the same diameter

Answers

Volume of a cylinder = pi r^2 h If the cone has exactly the same measurements then its formula is going to be
V_cone = 1/3 pi r^2 h. If that's the case the only difference is that the Cone's volume is 1/3 that of the cylinder
V_cone = 1/3 V_cylinder
V_cone = 1/3 136 cubic cm.
V_cone = 45.33 cubic cm.

What is the 32nd term of the arithmetic sequence where a1 = −33 and a9 = −121? −396 −385 −374 −363

Answers

The formula to find the general term of an arithmetic sequence is,

[tex] a_{n} =a_{1} +(n-1)d [/tex]

Where [tex] a_{n} [/tex]= nth term and

[tex] a_{1} [/tex] = First term.

Given, a9 = −121. Therefore, we can set up an equation as following:

[tex] -33+(9-1)d = -121 [/tex] Since, a1 = -33

- 33 + 8d = -121

-33 + 8d + 33 = -121 + 33 Add 33 to each sides of the equation.

8d = -88.

[tex] \frac{8d}{8} =\frac{-88}{8} [/tex] Divide each sides by 8.

So, d = - 11.

Now to find the 32nd terms, plug in n = 32, a1 = -33 and d = -11 in the above formula. So,

[tex] a_{32} = -33 +(32 -1) (-11) [/tex]

= -33 + 31 ( -11)

= - 33 - 341

= -374

So, 32nd term = - 374.

Answers

6 times 9 equals 54 marbles

Final answer:

Ken has a total of 54 marbles in all.

(-2,5) = (5,2); 270°

(5,2) = (-2,5); 90°

(-5,2) = (5,-2); 180°

(-5,-2) = (5,2); 180°

y = 5/4x - 10

-4y = -5x + 40
divide both sides by - 4

All colors of light are bent the same amount as they move from one material to another.

A) Always true.

B) Always false.

C) True, if you change bent to absorbed.

D) False, each color bends a different amount.

Answers

D is correct. This has to do with the frequency dependence of the index of refraction. This effect can be seen in prisms and is what allows them to break white light into its different colors (frequencies). If they all bent the same amount, the beam would stay together and the light leaving a prism would remain white. Also rainbows would not be possible, since they are made by light refracting at different angles inside spherical droplets of water in the earth's atmosphere.

D is the correct answer

You are a coffee shop owner and want to calculate the usual amount of money made each day, but you know that Fridays bring in more than double the revenue of any other day. Which measure of central tendency should you use?

A. Median
B. Mean
C. Mode
D. Any of the above

Answers

B (Mean) is the answer you are looking for
~Mathlete12321~

Final answer:

A. Median

The median is the most appropriate measure of central tendency for a coffee shop owner to use to calculate the usual daily revenue, as it is not skewed by the unusually high revenue on Fridays.

Explanation:

When considering which measure of central tendency to use for determining the usual amount of money made each day at a coffee shop, where Fridays bring in more than double the revenue of any other day, the best option would be the median. This is because the median is the middle point of the data distribution when the observations are ordered by their numerical values, and it is not affected by extreme values or outliers in the data.

The mean, or average, could be significantly skewed by the higher revenue on Fridays, thus not accurately depicting a typical day. The mode is the most frequently occurring value in the distribution, which may not be applicable to this situation unless you have multiple days with the exact same revenue.

Therefore, the median is most appropriate for this scenario as it is not influenced by the high revenue on Fridays and will provide a better indication of what a typical day's earnings might look like.

Answers

1/8PLANTS AN HOUR THNX

Samantha can pot 8 plants in one hour.

To calculate how many plants Samantha can pot in one hour, we need to determine the rate at which she pots plants. She currently pots 12 plants in 1 1/2 hours, which is equal to 1.5 hours.

To find the rate, we divide the number of plants by the number of hours:
12 plants /1.5 hours=8 plants per hour

Therefore, Samantha can pot 8 plants in one hour.
