Jeremy can row 3/8 of a mile in 1/4 of an hour. What is the unit rate that describes the miles per hour ?
Answers
3/8 * 4 = 1 1/2
Answer: Jeremy can row 1 1/2 miles per hour.
Hope this helps!
Answer:
The unit rate that describes miles per hour is 3/2.
Step-by-step explanation:
Jeremy can row 3/8 of a mile in 1/4 of an hour which means he takes 15 minutes.
If Jeremy can row 3/8 of a mile in 1/4 of an hour then he can row 3/8 multiply 4 of a mile in one hour.
Therefore,
Jeremy can row 3/2 of a mile in 1 hour.
Hence,
The unit rate that describes miles per hour is 3/2.

Answers
[tex] \dfrac{5}{6} - \dfrac{4}{6} = \dfrac{5-4}{6} = \dfrac{1}{6} \ cups[/tex].
Kade has 1/6 cup of salad dressing left after using some on a salad. We found this by converting 2/3 cup to 4/6 cup and then subtracting it from the 5/6 cup he initially had.
To find out how much salad dressing Kade has left after using some on a salad, we need to subtract the amount used from the total amount he made. Kade made 5/6 cup of salad dressing and used 2/3 cup on a salad. To perform the subtraction, both fractions need a common denominator. The smallest common denominator for 6 and 3 is 6. The fraction 2/3 can be converted to 4/6 so that both fractions have the same denominator. Now we can subtract:
Convert 2/3 cup to 4/6 cup (Since 3*2 = 6, and 2*2 = 4).Subtract 4/6 cup from 5/6 cup: 5/6 - 4/6 = 1/6 cup.Hence, Kade has 1/6 cup of salad dressing left after using it on the salad.

200 grams of fertilizer are used for each tree in an orchard containing 1200 trees. at $2.75 per kilogram of fertilizer, how much does it cost to fertilize the orchard ?
Answers
To fertilize an orchard of 1200 trees, with 200 grams of fertilizer per tree and the cost of fertilizer at $2.75 per kilogram, the total cost would be $660.
To calculate the cost to fertilize an orchard of 1200 trees, assuming 200 grams of fertilizer are used per tree, and the fertilizer costs $2.75 per kilogram, we need to follow these steps:
Convert the amount of fertilizer needed per tree into kilograms, as the cost is given per kilogram. Since there are 1000 grams in a kilogram, 200 grams is equal to 0.2 kilograms.
Multiply the amount of fertilizer needed per tree by the number of trees to find the total amount of fertilizer needed for the orchard. This is 0.2 kg/tree times 1200 trees = 240 kilograms.
Multiply the total kilograms of fertilizer by the cost per kilogram to find the total cost of fertilizing the orchard. This is 240 kg times $2.75/kg = $660.
Therefore, the total cost to fertilize the orchard is $660.

A business owner purchases supplies for a laundromat and a car wash.
Part A
The owner purchases 6 cases of laundry soap, 8 cases of fabric softener, and 3 cases of bleach for the laundromat. Each case of laundry soap costs $68.45, eash case of fabric softener costs $39.71, and each case of bleach costs $52.25.
Which is the best estimate of the total cast, in dollars, of the laundry items?
Answers
The best estimate of the total cast, in dollars, of the laundry items is $885.
What is total?A total is a whole or complete amount, and "to total" is to add numbers or to destroy something. In math, you total numbers by adding them: the result is the total.
Given that, the owner purchases 6 cases of laundry soap, 8 cases of fabric softener, and 3 cases of bleach for the laundromat.
Each case of laundry soap costs $68.45
So, the cost of 6 cases of laundry soap
= 6×68.45
= $410.7
Each case of fabric softener costs $39.71
So, the cost of 8 cases of fabric softener
= 8×39.71
= $317.68
Each case of bleach costs $52.25
So, the cost of 3 cases of bleach for the laundromat
= 3×52.25
= $156.75
Total =410.7+317.68+156.75
= $885.13
≈ $885
Therefore, the best estimate of the total cast, in dollars, of the laundry items is $885.

The table shows the change in the low temperature in Albany compared to the day before.
Wednesday : +3.5
Thursday: -4.1
Friday : 0
Saturday: -2.2
On which day did the low temperature change the most?
Answers
Answer: On Thursday the low temperature change the most.
Explanation :
From the given table we can conclude that change is the lowest in Thursday .
And there is no matter if it is positive or negative
Because change defines final - initial only i.e. difference between final and initial
So, we consider absolute value only.
According to which Thursday has the atmost change i.e 4.1 which is the lowest amongst the other .
So ,on Thursday the low temperature change the most.
The day with the most temperature change in Albany compared to the day before is Thursday.
The day with the most temperature change was Wednesday.
To determine the most significant change, we calculate the absolute difference for each day's temperature change:
Wednesday: |+3.5| = 3.5Thursday: |-4.1| = 4.1Friday: |0| = 0Saturday: |-2.2| = 2.2Therefore, Thursday had the most substantial temperature change.

you are asked to determine if the two events "a randomly selected student has asthma" and "a randomly selected student has a household member who smokes" are independent. what probabilities could you calculate to answer this question?
Answers
event A = student has asthma
event B = at least one household member smokes
To find the probability of event A happening, we count the total number of people who have asthma out of the total in the survey. So we simply look at the "student has asthma" row and look at the "total" column. This value is 182. There are 182 people who have asthma. This is out of 937 (bottom right corner).
Divide the values: 182/937 = 0.194237
This value is approximate
So P(A) = 0.194237 approximately
The P means probability
P(A) = probability of event A happening
----------------------------------
Now compute P(B)
P(B) = 395/937
P(B) = 0.421558
Notice I'm dividing the total value in the "at least one member smokes" column over the grand total of 937
----------------------------------
Next we compute P(A and B) which is the probability both events occur at the same time.
P(A and B) = 113/937
P(A and B) = 0.120598
The 113 is the amount of people who have asthma AND have at least one household member that smokes (row1, column2)
----------------------------------
If events A and B were independent, then P(A)*P(B) should be equal to P(A and B)
Let's see if that is the case
P(A and B) = P(A)*P(B)
0.120598 = P(A)*P(B)
0.120598 = 0.194237*0.421558
0.120598 = 0.08188216
we get two different results so P(A and B) = P(A)*P(B) is not true
Therefore, A and B are not independent events. They are said to be dependent events.

What is the same as 98.52 divided by 10
Answers
Dividing 98.52 by 10 involves moving the decimal one place to the left, resulting in 9.852. This process is the same for all decimals when dividing by powers of 10, such as 10, 100, or 1000.
When we divide a number by powers of 10, we're effectively moving the decimal point to the left by as many places as there are zeros in the power of ten. For instance, dividing 1.9436 by 10 moves the decimal one place to the left, becoming 0.19436. Similarly, dividing 98.52 by 10 moves the decimal one place to the left as well, giving us the simplified answer of 9.852.
If we were to multiply a number by powers of 10, we would do the opposite, moving the decimal to the right. For example, to multiply 45.86 by 100, you would move the decimal two places to the right to get 4586.
In conclusion, 98.52 divided by 10 is 9.852. Even if the answer is rounded, the process remains the same; you simply adjust the decimal point accordingly based on the power of 10 you are dividing by.
