Answer:
60 miles
Step-by-step explanation:
Distance apart = 100
Rate of travel. :
Anthony = 12 mph
Cleopafda = 8 mph
Using the relation :
Speed = distance / time
Distance = speed * time
If they leave at the same time, travel time Can be represented as x
Anthony's distance + Cleopafda distance = total distance
12x +. 8x = 100
20x = 100
x = 5
Hence, they both traveled for 5 hours before meeting.
Distance covered by Anthony :
Speed * time
12 mph * 5h = 60 miles
Anthony must travel. For 60 miles.
introduces a study where researchers studying the relationship between honesty, age, and self-control conducted an experiment on 1G0 children between the ages of 5 and 15. The researchers asked each child to toss a fair coin in private and to record the outcome (white or black) on a paper sheet, and said they would only reward children who report white. Half the students were explicitly told not to cheat and the others were not given any explicit instructions. Differences were observed in the cheating rates in the instruction and no instruction groups, as well as some differences across children's characteristics within each group. (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:
The solution to this question can be defined as follows:
Step-by-step explanation:
In choice a:
Both children between 5 and 15 years old and 160 years old are also the populations of interest, and Kids from 5 to 15 years of age.
In choice b:
These findings could be compared like we do not know whether the groups were randomly selected, and the allocation is still not random; there could be no casual conclusion because the statement is valid even With sample research, and after randomization, filtering, and testing of 160 specimens (instruction vs no-instruction) Its analysis can be common to the community and replicated. There could be explanatory relations generated by experimental research. This analysis is observational and can therefore be used Causal relationships are established.gggg

Elena paints the back of a aquarium it has a height of 1 3/4 feet the painted area is 5 5/6 what is the length
Answer:
3 1/3 feets
Step-by-step explanation:
Given that:
Height of aquarium = 1 3/4 feets
Area of aquarium = 5 5/6 ft²
The length of aquarium = x
Aquarium is shaped in the form of a rectangle :
Area of a rectangle = Length * width
5 5/6 = x * 1 3/4
35/6 = 7x/4
Cross multiply :
7x * 6 = 35 * 4
42x = 140
x = 140 / 42
x = 3 14/42
x = 3 1/3 feets
Hence, Length of the back of aquarium is 3 1/3 feets

A store is having a 20% off sale on all merchandise 1. If Mai buys one item and saves $13 what was the original price
Answer: $65
Step-by-step explanation:
The store is having a 20% off sale.
Mai buys an item and saves $13.
This means that $13 is 20% of the price of the item that Mai bought.
Assume the original price is x. Expression is:
x * 20% = 13
x = 13/20%
x = $65

Answer:
Three fifths
Step-by-step explanation:
Since 10 was divided by 2 to get 5,
you just do the same to the top half of the fraction.
So when you divide 6 by 2, you get 3.
So it is equal to 3/5, or three fifths.
And 3/5 is equivalent to 6/10

4 2/5+k=−3 2/11
Need help
Answer:
2/11
Step-by-step explanation:
Here we have two mixed numbers. Be very careful when handeling negative mixed numbers. Don't coonfuse "-3 2/11" with "-3 + 2/11"
4 2/5 + k = -3 2/11
I add a minus into the mixed fraction on the right. Of course you don't have to write an entire new line when you do calculations on paper.
4 2/5 + k = -3 -2/11
k = - 3 - 4 - 2/5 - 2/11
k= - 7 -2/5 -2/11
Make common denominators. Both 11 and 5 is prime numbers (numbers that are only divisible by one and itself). Therefore the common denominator is 5*11=55.
k= - (7*55)/55 - (2*11)/(5/11) - (2*5)/(11*5)
k = - 385/55 - 22/55 -10/55
k = - (385 +22+10)/55
k = - 417/55
Since 417 isn't divisible by neither 11 nor 5, this fraction is in it's simplest form.
btw correct me if i am wrong
Answer:
[tex] k = - 1 \frac{12}{55} [/tex]
Step-by-step explanation:
[tex]4 \frac{2}{5} + k = 3 \frac{2}{11} \\ \frac{22}{5} + k = \frac{35}{11} \\ k = \frac{35}{11} - \frac{22}{5} \\ k = \frac{175 - 242}{55} \\ k = \frac{ - 67}{55} \\ k = - 1 \frac{12}{55} [/tex]

Find the y-intercept of the line on the graph.
Enter the correct answer
Given:
The graph of a line.
To find:
The y-intercept of the line.
Solution:
y-intercept of a line is the point at which the line intersect the y-axis.
We have, graph of the line.
From the given graph it is clear that the line intersect the y-axis at (0,4).
So, y-intercept is at point (0,4).
y-intercept = 4
Therefore, the y-intercept is 4.

The time, t, in seconds, required for an object accelerating at a constant rate of a meters/second to travel a distance of d meters is given by this equation.
t=√2d/a
Which equation expresses d in terms of t and a?
A. d=2at^2
B. d=√2t/a
C. d=at^2/2
D. √a/2t
Answer:
(A)
Step-by-step explanation:
Option A. d=2at^2
720
Plato.
t=√2d/a
12=√2d/10
12²=(√2d/10)²
144=2d/10
2d=(144)(10)
d=1440/2
=720
Can an object accelerate if it's moving with constant speed?
Yup! Many people find this counter-intuitive at first because they forget that changes in the direction of motion of an object—even if the object is maintaining a constant speed—still count as acceleration.

Approximate: log5 ^4/7
Answer:
log5 (4/7)= log5 (4)- log5 (7)=-0.347708839
Step-by-step explanation:
for the first question which would be Approximate: log5 4/7 the answer would be B. –0.3477
and for the second question which would be Approximate: log1/2 5 the answer would be C.–2.3219
Step-by-step explanation: Using Properties of Logs
logb(x/y) = logbx - logby.
Furthermore
log5 (4/7)= log5 (4)- log5 (7)
Solve log 5 (4) and log 5 (7) with the base change of the logarithm
log 5 4 = log 4 / log 5
Use the calculator (DESMOS): log 5 4 =0.8613531161
log 5 7 = log 7 / log 5
log 5 7 =1.2090619551
Therefore, The answer is, log5 (4/7)= log5 (4)- log5 (7)=-0.347708839
For the second part of the question just to not make this too long the answer to the second part is: C ( -2.3219 )

what happens to the kinetic energy of the particles in a substance when it is heated
Answer:
Step-by-step explanation:
The kinetic theory of matter can be used to explain how solids, liquids and gases are interchangeable as a result of increase or decrease in heat energy. When an object is heated the motion of the particles increases as the particles become more energetic
