Martin cycles at an average speed of 12mph. On Tuesday, he leaves his house at 9:15am
and goes on a bike ride for 40 miles. What time does he arrive home?
Step-by-step explanation:
40÷12= 3.33
so it approximately takes him 3hrs and 18minutes
so 9:15 + 3hrs 18 minutes is 12: 33 pm?

The rate of decay of a radioactive substance depends upon the
amount present initially. The mass y (mg) of the radioactive substance
cobalt-60 present in a sample at time < (years) is represented by the
-0.13151
exponential equation y = 50 e
Answer the following questions in complete sentences.
1. How does the exponential equation above compare to the equation
for simple interest that is compounded continuously? Explain the
similarities. What is the initial amount of cobalt-60 in the sample?
2. How much cobalt-60 is left after 8.4 years? Show your work
3. What would be the y-intercept of the graph? What does it
represent?
4. After how many years will the amount of cobalt-60 left be 6.25

The town of Rayburn received 7 more inches of snow than the town of Greenville. Let g represent the amount of snow in Greenville. Enter an algebraic expression to represent the amount of snow in Rayburn. The algebraic expression that can be used is
Answer:
r = g + 7 (let "r" be amount of snow rayburn got)
Step-by-step explanation:
Lets let r = the amount of snow rayburn got.
r = g + 7

An employee gets a signing bonus of $100 and is paid $25 per hour they work. Represent this scenario by writing an equation for x hours worked
Answer:
$(100 + 25x )
Step-by-step explanation:
X= number of hours
The numbers are just like money just without the dollar sign
100 + 25(x)
After you get your number remember to put your sign you were looking for
Hope I helped you out:)
Answer:
$(100 + 25x)
Explanation:
if the employee works for 1 hour, they earn 1 × $25 = $25. if they work for 2 hours, they earn 2 × $25 = $50. thus, representing the number of hours they work by x, we can say that they earn $(25x) per hour.
now, we add on the signing bonus: $(100 + 25x).
i hope this helps! :D

First you need to group numbers of like terms in one side. Then when you take the other number to the other side of equal sign changes it's form eg +6 change to - 6
The results of an independent-samples t test were t(19) = 4.02, p < 0.05. In this example,
the sample size is:
The results of an independent-samples t test were t(19) = 4.02, p < 0.05. The sample size is 19.
What is independent t-test?The independent t-test is a defined as an statistical test in order to determine if we have statistically significant difference between the means of two unrelated groups.
Effect size is defined as a "quantitative measure of the magnitude of the experimenter effect" So, If we have a high value for the effect size then we can conclude that we have a stronger relationship between two variables.
T test is used to compare group means is one of the most common tests and is used to determine whether the means of two groups are equal to each other.
We perform one sample z-test;
One sample z-test is performed if the sample size is large enough (n > 30) and we want to know if the sample comes from the specific population.
The results of an independent-samples t test were t(19) = 4.02, p < 0.05. In this example,
The sample size is 19.

there are 240 students who attend Elmwood school. Two thirds of the students have brown hair. how many students have brown hair? how many students do not have brown hair?
Answer:
160 has brown hair while
80 do not have brown hair
Step-by-step explanation:
two third means 2/3
therefore to find how many student have brown hair,
we say- 2/3 x 240 = 160
since we know that 160 students have brown hair, we just subtract it from 240
i.e 240 - 160 = 80

180-104 is 76 76-10=66 66/2 is 33
Answer: x = 33
Step-by-step explanation:
Well since that line is basically equal to 180 all you have to do is plug in those numbers for x. Since 33 + 10 = 43 Alll you gotta do is add that up. So we have 104 + 33 + 43 = 180. I’m not the best at explaining things but I hope this helped :)
A rectangular picture is twice as long as it is wide. If the
area of the picture is 288 in^2, what are its dimensions?
The dimensions of the picture are_____ in long by_____ in wide.
Answer:
24 in long by 12 in wide.
Step-by-step explanation:
l=2w
288=(2w)×w
288=2w^2
144=w^2
12=w
width is 12 inches. Plug that in to find length...
l=2×12
l=24
