Answer:
ASA
Step-by-step explanation:
The Proof proves that two of the angles and the included side are equal making it the ASA theorem
The missing reason in the given proof is ASA.
What is Congruence of Triangles?Two or more triangles are said to be congruent if and only if sides and angles of one triangle is equal to the corresponding sides and angles of another triangle.
Given is a proof for the congruence of the lines HG and EG.
Given,
G is the midpoint of KF.
KH ∥ EF
Triangles F E G and K H G are connected at point G.
We have to prove HG ≅ EG.
From the given steps of proof,
we get two angles and the included side of triangle FEG is congruent to corresponding two angles and the included side of triangle KHG.
So by ASA theorem both triangles are congruent.
Hence the missing reason is ASA.

Carlos can run 5 miles in 45 minutes, Kelly can run 10 miles in 80 minutes, and Mick can run 30 miles in 170 minutes
Answer:
Mick can run farther in less time if that's the question
Step-by-step explanation:
Mick's speed is faster.
What is speed?Speed is the ratio of distance and time.
It shows how fast an object is moving at a given time.
We have,
Carlos can run 5 miles in 45 minutes.
45 minutes = 45/60 = 0.75 hours
Speed.
= 5/0.75
= 6.66 miles per hour.
Kelly can run 10 miles in 80 minutes.
80 minutes = 1.33 hours
Speed.
= 10/1.33
= 7.5 miles per hour.
Mick can run 30 miles in 170 minutes
170 minutes = 2.8 hours
Speed.
= 30/2.8
= 10.7 miles per hour

What is the slope of the line that crosses points (6, 9) and (10, 11)
[tex]slope\; is\; unknown~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~[/tex]
Answer:
2/4 or 1/2
Step-by-step explanation:
slope is rise/run, so count how many points are between your x-values and how many are between your y-values. there are 4 points between the x's and 2 between the y's.
y-axis is the rise because it goes up and down
x-axis is the run because it's horizontal
rise/run= 2/4= 1/2 because you always simplify.

An individual saves $5000 in a bank account at the beginning of each year for 10 years.
No further savings or withdrawals are made from the account. Determine the total amount saved if the annual interest rate is 8% compounded:
(a) annually;
(b) semi-annually.
Answer:
a) Amount saved if the interest is compounded annually is $5832
b) Amount saved if the interest is compounded semi-annually is $5849.5
Step-by-step explanation:
Principal Amount P = 5000
Time t = 10 years
Annual interest i = 8% = 0.08
We need to find amount saved if interest is compounded a) annually b) semi-annually
a) Amount saved if the interest is compounded annually
If interest compounded annually, n= 1
Using Formula: [tex]A=P(1+\frac{r}{n})^{nt}[/tex]
Putting values:
[tex]A=P(1+\frac{r}{n})^{nt} \\A=5000(1+\frac{0.08}{1})^{1*2}\\A=5000(1+0.08)^2\\A=5000(1.08)^2\\A=5000(1.1664)\\A=5832[/tex]
So, Amount saved if the interest is compounded annually is $5832
b) Amount saved if the interest is compounded semi-annually
If interest compounded semi-annually, n= 2
Using Formula: [tex]A=P(1+\frac{r}{n})^{nt}[/tex]
Putting values:
[tex]A=P(1+\frac{r}{n})^{nt} \\A=5000(1+\frac{0.08}{2})^{2*2}\\A=5000(1+0.04)^4\\A=5000(1.04)^4\\A=5000(1.1699)\\A=5849.5[/tex]
So, Amount saved if the interest is compounded semi-annually is $5849.5
(a). When compounded annually, the amount will be [tex]\$ 10,794.6[/tex]
(b). When compounded semi-annually, the amount will be [tex]\$ 10,955.6[/tex]
Compound interest:It is given that, an individual saves $5000 in a bank account at the beginning of each year for 10 years.
[tex]Principal(P)=5,000, t=10 years, rate(r)=8\%[/tex]
As we know that,
[tex]Amount=P(1+\frac{r}{100} )^{t} \\\\Amount=5,000(1+\frac{8}{100})^{10} \\\\Amount=5,000*(\frac{108}{100})^{10}\\\\Amount=\$ 10,794.6[/tex]
When interest is compounded semi-annually;
[tex]r=8/2=4\%, t=10*2=20[/tex]
[tex]Amount=5,000(1+\frac{4}{100})^{20} \\\\Amount=5,000*(\frac{104}{100})^{20}\\\\Amount=\$ 10,955.6[/tex]

Emma and her children went into a restaurant where they sell hotdogs for $4 each and drinks for $1.50 each. Emma has $30 to spend and must buy no less than 9 hotdogs and drinks altogether. If xx represents the number of hotdogs purchased and yy represents the number of drinks purchased, write and solve a system of inequalities graphically and determine one possible solution.
Answer:
6 hotdogs and 4 drinks
Step-by-step explanation:
4x + 1.50y = 30
For questions like this, you can do the equation that represents the price of the products first.
x + y [tex]\geq[/tex] 9
After that, you can write the equation that represents the quantities.
Now, you just have to graph it to find the solution. When you're graphing, make sure that y is alone on one side. Here's how you rearrange the equations:
The first equation:
4x + 1.50y =30
*Subtract 4x from both sides, which leads to:
1.50 y = -4x + 30
*Divide by 1.50 on both sides, which leads to:
y = -2.66x + 20
The second equation:
x + y [tex]\geq[/tex] 9
*Subtract x from both sides, which leads to:
y [tex]\geq[/tex] -1x + 9
Now, use any graphing calculator (I prefer Desmos) to graph these two equations. In fact, you can just graph it on paper, too.
Here is the graph: (it is attached as a file)
You can look for any points that are on the red line but are also shaded blue. Make sure you look only in Quadrant 1- don't go into the negatives! One good point to choose would be (6,4)- this means that you buy 6 hotdogs and 4 drinks.
Answer:

Complete question is;
When high-density groups are separated by areas of low abundance, this distribution is termed: Group of answer choices
A) random distribution pattern
B) uniform distribution pattern
C) logistic distribution pattern
D) clumped distribution pattern
Answer:
D: Clumped Distribution Pattern
Step-by-step explanation:
Looking at the options, the correct option is Clumped distribution pattern.
This is because in density and dispersion phenomenon, Clumped patterns will normally occur when resources get concentrated in small areas within a larger habitat or due to individuals that form social groups. However,on large spatial scales, majority of organisms will likely have clumped distributions mainly because their habitats are not distributed uniformly over wide areas.

A and B start toward each other at the same time from points 150 miles apart.
If A went at the rate of 20 miles an hour, at what rate must B travel if they
meet in 5 hours?
Answer:
B must travel at the rate of 10 miles per hour.
The speed at which B should travel is 10 mph
What is Speed?
Speed is defined as the rate of change of position of an object in any direction. Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude
Speed = Distance / Time
Given data ,
Let the distance between A and B be D = 150 miles
Now , the equation will be
The speed of A = 20 mph
Let the speed of B be = B
The time required T = 5 hours
From the equation , Distance = Speed x Time
Substituting the values in the equation , we get
150 = ( A x T ) + ( B x T )
20 x 5 + ( B x 5 ) = 150
On simplifying the equation , we get
100 + 5B = 150
Subtracting 50 on both sides of the equation , we get
5B = 50
Divide by 5 on both sides of the equation , we get
B = 10 mph
Therefore , the value of B is 10 mph
Hence , the speed of B is 10 mph
