Answer:
to the shop : 5/8 of an hour
back home : 3/8 of an hour
Step-by-step explanation:
We use the relationship between distance travelled, speed and time given by the formula:
speed = distance / time
We know that the distance from home to the coffee shop is D (same for trip back)
We also know the two speeds in one direction 9 mph and in the other 15 mph
then we can find the times t1 (to the coffee shop) and back (t2) by using the equations:
D = 9 * t1
D = 15 * t2
1 = t1 + t2
We set the two distances equal to have:
9 * t1 = 15 * t2
then t1 = 15 * t2 / 9 = 5 t2 / 3
and use this to substitute for t1 in the last equation:
t1 + t2 = 5 t2/3 + t2 = 1
8 t2 /3 = 1
then t2 = 3/8 of an hour
and therefore t1 must be 1 - t2 = 5/8 of an hour

90 divided by 3 + ( 3 - 2 ) - 20.
Answer:
11
Step-by-step explanation:
first 3-2=1 the divide 90 by 3 then add the 1 the subtract that by 20 and you will get 11
The result of the expression 90 divided by 3 plus the quantity (3 minus 2) minus 20 is 11.
To evaluate the expression 90 divided by 3 + (3 - 2) - 20, we can follow the order of operations (also known as PEMDAS/BODMAS), which stands for Parentheses/Brackets, Order/Exponents, Division/Multiplication, and Addition/Subtraction:
First, let's simplify the expression within the parentheses:
3 - 2 = 1
Now we can substitute the simplified expression back into the main expression:
90 ÷ 3 + 1 - 20
Next, perform the division:
90 ÷ 3 = 30
Now we have:
30 + 1 - 20
Next, perform the addition:
30 + 1 = 31
Finally, perform the subtraction:
31 - 20 = 11
Therefore, the value of the expression 90 divided by 3 + (3 - 2) - 20 is 11.

John can walk 6 dogs in 3 hours. Susie can walk 7
dogs in 2.5 hours. How long would it take them to
walk 15 dogs together?
Answer:
It would take them 6.5 hours to walk 15 dogs together.
Step-by-step explanation:
John can walk 2 dogs in 1 hour.
If you multiply that by 3, he can walk 6 dogs in 3 hours.
So that means he can walk 8 dogs in 4 hours.
Susie can walk 7 dogs in 2.5 hours.
Meaning that if you add 8 dogs plus 7 dogs, you get 15 dogs.
Meaning that if you add 4 hours plus 2.5 hours, you get 6.5 hours.
That being said, they can both walk 15 dogs TOGETHER in 6.5 hours.

Answer:
10/8 or 1.25
Step-by-step explanation:
We can write this into an equation to help us understand what we need.
3/4=0.60x
We can make these both into fractions to make it easier.
3/4=6/10x
Divide both sides by 6/10, or multiply both sides by 10/6.
3/4×10/6=30/24=10/8=1.25

Josh has a $250 gift card to Under Armour.
He plans to buy as many pairs of shorts as he
can. The cost of each pair is $22.50. There is also
a single shipping charge of $6.50. How many
pairs of shorts can he afford without spending
more than his gift card amount? Write the
inequality, then solve, and state your answer.
Answer:
8 pairs
Step-by-step explanation:
250/29 = 8.6
so 8 is the answer cause you probably can't cut them in half
Answer:
10 pairs
22.50x+6.50<_250
Step-by-step explanation:
If you do 22.50 times 10 you get 225 then you add 6.50 which would give you 231.50. You cant add any more pairs of shoes because you would go over the $250 limit. For example if you added 22.50 one more time you would be at 254. Therefore it would be 10 pairs of shoes.

Exercise 1.6 introduces a study on the relationship between socio-economic class and unethical behavior. As part of this study 129 University of (California Berkeley undergraduates were asked to identify themselves as having low or high social-class by comparing themselves to others with the most (least) money, most (least) education, and most (least) respected jobs. They were also presented with a jar of individually wrapped candies and informed that the candies were for children in a nearby laboratory, but that they could take some if they wanted. After completing some unrelated tasks, participants reported the number of candies they had taken. It was found that those who were identified as upper-class took more candy than others.
A. Identify the population of interest and the sample in this study.
B. Comment on whether or not the results of the study can be generalized to the population, and if the findings of the study can be used to establish causal relationships.
Answer:
(A) Population: UCB undergraduates
Sample: The selected 129 UCB undergraduates
(B) Yes, they can be generalized to the population
No, the findings of this single study cannot be used to establish causal relationships between socio-economic classes and unethical behaviors.
Step-by-step explanation:
STUDY: Relationship between socio-economic class and unethical behavior.
The bases for determining social class here are: money, education, and respected job.
RESULT: Those who identified as upper class took more candy than others.
(A) Identify the population of interest and the sample, in this study.
The population of interest in this study is UCB undergraduates.
The sample in this study is the 129 UCB undergraduates who were selected and who agreed to take part in the experiment. They were the participants who were divided into the two social classes before the experiment was conducted.
(B) The results of the study can be generalized to the population of UCB undergraduates since it's likely that the results would be same in another group of 129 UCB undergraduates.
The findings or results of the study cannot be used to establish causal relationships unless the study is conducted in more universities and majority of the results are same with this.

Answer:
I'm not 100% sure, but I do think it is
0.042768
But it is asking for percentage, and says to round 3 decimal places, making it confusing whether you round 0.042768 first, or you round the percentage of 4.2768%. I would argue with your teacher, as the excuse of why this was turned in late.
Step-by-step explanation:
It is either 4.277% or 4.3%.
Yes, you may wonder why the second possibility is just a rounded form of the first answer. It is due to rounding to three decimal places first, as 0.042768 rounded to three places is 0.043 because the 7 is more than 4 blah blah blah kiddy rhymes from elementary school yeah.
That would become 4.3%.
But 0.042768 if you turn it to a percent first is 4.2768% which becomes 4.277% if you round it afterwards. Argue this to a teacher or something.

Given that M is the midpoint of line segment AC, AM = x + 20, and MC = 5x - 4. Find the lenght of AM.
Answer:
6 units
Step-by-step explanation:
AM = MC
AM = x + 20
MC = 5x - 4
x + 20 = 5x - 4
20 = 4x - 4
24 = 4x
x = 6
The required length of the AM is 27.
Given that,
M is the midpoint of line segment AC,
AM = x + 20, and MC = 5x - 4.
To find the length of AM.
The midpoint is that point the line whose distance from both the ends of the line is equal.
Here,
M is the midpoint of line segment AC, i.e.
AM = AC - - - - - - - - - - -- - - (1)
AM = x + 20, and MC = 5x - 4
Put AM and MC in equation 1
x + 20 = 5x - 4
5x - x = 20 + 4
4x = 24
x = 24 / 4
x = 7
Now,
Length AM = x + 20
Length AM = 7 + 20
Length AM = 27
Thus, the required length of the AM is 27.

25x + 15y=17
25x + 15y=305$
Neee answer ASAP
Answer:
1st. Problem
Let's solve for x.
25x+15y=17
Step 1: Add -15y to both sides.
25x+15y+−15y=17+−15y
25x=−15y+17
Step 2: Divide both sides by 25.
25x/25 = -15y+17/ 25
x equals...
x= -3/5 y + 17/25
2nd. Problem
Let's solve for x.
25x+15y=305
Step 1: Add -15y to both sides.
25x+15y+−15y=305+−15y
25x=−15y+305
Step 2: Divide both sides by 25.
25zx/25 = -15y305/25
x equals...
x = -3/5 y + 61/5

F(x)=1-3x;x=4,x=4+h
Determine net change and average change between the given values of the variables
f(x) = 1-3x, x = 4 , x = 4+h
(a) find the net change of f(x):
f1= f(x=4) = 1-3(4) = 1 - 12 = -11
f2= f(x=4+h) = 1-3(4+h) = 1-12 + 3h = -11 - 3h
Net change = f2 - f1 = -11 -3h - -11 = -3h
(b) average rate of change = slope = (f2 - f1)/(x2-x1) = -3h/((4+h)-4 =-3
