Answer:
y = x+2
Step-by-step explanation:
First find the slope using two points (0,2) and (5,7)
m = (y2-y1)/(x2-x1)
= (7-2)/(5-0)
= 5/5
= 1
We have the y intercept ( where it crosses the y axis) =2
y = mx+b where m is the slope and b is the y intercept
y = 1x +2
y = x+2
=============================================================
Explanation:
The two red points are (0,2) and (5,7)
Find the slope of the line through (x1,y1) = (0,2) and (x2,y2) = (5,7)
Use the slope formula
m = (y2 - y1)/(x2 - x1)
m = (7 - 2)/(5 - 0)
m = 5/5
m = 1
The slope is m = 1.
The y intercept is b = 2 as this is where the diagonal line cuts through the y axis.
Therefore y = mx+b turns into y = 1x+2, which is the same as y = x+2
This says: "whatever the input x is, add 2 to it to get the y output". So for instance, if the input is x = 5, then we add on 2 to get y = x+2 = 5+2 = 7. This shows how (5,7) is one point on the diagonal line.

Tyler just lit a new candle and then let it burn all the way down to nothing. The initial length of the candle was 15 inches and the candle burned at a rate of 1.25 inches per hour. Write an equation for L,L, in terms of t,t, representing the length of the candle remaining unburned, in inches, tt hours after the candle was lit.
Answer:
15 in - (1.25 in/hr)t
Step-by-step explanation:
L(t) is a function of time, t: L(t) = 15 in - (1.25 in/hr)t
Note that when the candle has burned down to nothing, L(t) = 0. How long does that take? Set 15 in - (1.25 in/hr)t equal to zero and solve for t:
(1.25 in/hr)t = 15 in, or
15 in
t = ---------------- = 12 hrs
1.25 in/hr

Student Friendly Bank pays a simple interest rate of 2.5% per year. Neighborhood Bank pays a compound interest rate of 2.1% per year, compounded monthly.
The question is incomplete:
Student Friendly Bank pays a simple interest rate of 2.5% per year. Neighborhood Bank pays a compound interest rate of 2.1% per year, compounded monthly.
Which bank will provide the largest balance if you plan to invest $10,000 for 10 years? For 20 years?
Answer:
-The bank that provides the largest balance if you plan to invest $10,000 for 10 years is Student Friendly Bank.
-The bank that provides the largest balance if you plan to invest $10,000 for 20 years is Neighborhood Bank.
Step-by-step explanation:
First, you have to calculate the balance if you invest the money in Student Friendly Bank. To do it, you have to use the simple interest formula to calculate the future value:
FV=PV(1+rt)
FV= future value
PV= present value
r= rate
t=time
-10 years:
FV= 10,000(1+(0.025*10))
FV= 10,000(1+0.25)
FV=10,000(1.25)
FV=12,500
-20 years:
FV= 10,000(1+(0.025*20))
FV= 10,000(1+0.5)
FV=10,000(1.5)
FV=15,000
Second, you have to calculate the balance if you invest the money in Student Neighborhood Bank. To do it, you have to use the compound interest formula to calculate the future value:
FV=PV(1+(r/m))^mt
FV= future value
PV= present value
r= rate
t=time
m=number compounding periods per year
-10 years:
FV=10,000*(1+(0.021/12))^12*10
FV=10,000*(1+0.00175)^120
FV=10,000*(1.00175)^120
FV=12,334.5
-20 years:
FV=10,000*(1+(0.021/12))^12*20
FV=10,000*(1+0.00175)^240
FV=10,000*(1.00175)^240
FV=15,214
According to this, the bank that provides the largest balance if you plan to invest $10,000 for 10 years is Student Friendly Bank because it will provide $12,500 and Neighborhood Bank will provide $12,334.5.
The bank that provides the largest balance if you plan to invest $10,000 for 20 years is Neighborhood Bank because it will provide $15,214 and Student Friendly Bank will provide $15,000.

1,784 rounded to the nearest ten
Answer:
1,784=1,780
Step-by-step explanation:
because the tens column is 4,it is not greater than 5 but less than 5.due to this, the 1,784 becomes 1,780 because in this a number less than five will automatically become 0
The answer is 1,780

What is 275 divided by 20 in lowest form? Please explain it like you would explain it to a 4 yr old cuz I’m really stupid. I keep getting 13 remainder of 15 but when I look it up it says it 13 3/4 so what do I do to go from 13 remainder of 15 to 13 3/4?
Answer: So think about it this way. 20 goes into 200 ten times, right?
After that, you have 75 left. 20 goes into 60 3 times. After that, you have 15 left.
But wait, 20 can't go into 15 as a whole. So you have to make that a fraction.
15/20. That fraction can be simplified! Divide each part by five. The you get 3/4.
So add up the times you put 20 in. First it was 10 to get to 200, then it was 3 to get to 60. Then it was 3/4 to get to 15.
Now you have 13 3/4

Chris has a bucket with paper clips. It has 9 green paper clips and 21 orange paper clips. Chris randomly draws a paper clip, records the color, and returns the paper clip to the bucket. After doing 10 experiments, he found that he drew an orange paper clip 70% of the time. What kind of comparison can be made?
The percentage is likely to decrease with more trials. Or, the percentage is likely to remain the same with more lanes. Or the percentage will likely increase with more experiences.
Answer:
likely remain the same
Step-by-step explanation:
as their ratio from green to orange paper clips is 9:21 meaning it is very likely to draw a orange. If calculated 9/30 is 30 percent meaning there is a 30 percent chance of drawing green. We can conclude there is a 70 percent chance of drawing green mathematically
A geometric sequence is represented by a Subscript n Baseline = a Subscript 1 Baseline r Superscript n minus 1. What is the fifth term of a geometric sequence where a Subscript 1 Baseline = 4,096 and the common ratio is Negative one-fourth?
Answer:
16Step-by-step explanation:
Given the nth term of a geometric sequence represented as [tex]Tn = a_1r^{n-1}[/tex]
[tex]a_1[/tex] = first term of the sequence
n = number of terms
r = common ratio
Given [tex]a_1 = 4,096,\ r = -\frac{1}{4} , n = 5[/tex](fifth term of the sequence)
[tex]T_5 = 4,096(-\frac{1}{4} )^{5-1}\\ T_5 = 4,096(-\frac{1}{4} )^{4}\\T_5 = 4,096(\frac{1}{256} )\\T_5 = 16[/tex]
The fifth term of the geometric sequence is 16

Answer:
x=29.9 degrees
Step-by-step explanation:
Sides we are given: x and side length of 92.
Angle we are given: angle of measure 18.
Relative to the angle we are given, we have the opposite and adjacent sides, so we use TOA, as O is opposite and A is adjacent.
Tangent 18= x/92
Tangent 18 (92)=x
x=29.9 degrees
Answer:
29.9 to one decimal place
Step-by-step explanation:
To work out X you can find the missing angle by doing;
[tex]180 - (90 + 18) = 72[/tex]
Then use Sine rule to work out X;
[tex]x = \frac{92}{ \sin(72)} \times \sin(18) \\ x = 29.89261.....[/tex]

determine if each polygons are similar, if so, write the similarity statement and the similarity ratio. if not explain why.
Answer:
They are not similar
Step-by-step Explanation:
For two polygons to be considered similar, two conditions must be met:
1. The ratio of their corresponding sides must be equal, and must have the same scale factor.
2. Their corresponding angles must be the same. That is, the corresponding angles must be congruent.
Now let us examine the two polygons ( ∆AYP and ∆BOX) given to ascertain if they are similar.
First, we can observe that only two of their corresponding sides were given. The third corresponding side, "YP/OX" is not given. This makes it difficult for us to tell if the polygons are similar, if we are to base our conclusion on merely considering the ratio of their corresponding sides.
Although, the two given corresponding sides (AY/BO & AP/BX), both have equal ratio ⅖, i.e. AY/BO = AP/BX = ⅖. This is not enough to tell both polygons are similar, as we cannot tell if the third corresponding side would give us same ratio, since it wasn't given in the diagram.
==>Next is to examine the interior angles of the polygons, whether the measure of their corresponding angles are the same.
Thus, from the diagram, we can see that two angles of the each triangle were given. We can find the measure of the third angle not given since we know that sum of the interior angles of a triangle = 180°
Thus, <P in ∆AYP = 180 - (90+20) = 180 - 110
<P = 70°
Thus, <B in ∆BOX = 180 - (90+80) = 180 - 170
<B = 10°
From the above calculation, comparing both polygons having known the measures of their corresponding angles, we can conclude that both polygons given in the question are not similar.
This is because the measure of their corresponding angles are not congruent.
<A is not congruent to <B, so likewise with <P and <X.
Jorge and Jillian have cell phones with different service providers. Jorge pays $50 a text month and $1 per text message sent. Jillian pays $72 a month and $0.12 per text message sent. How many texts would each of them have to send in order for their bill to be the same amount at the end of the month?
Answer:
When they send 25 texts each, their bills will be equal
Step-by-step explanation:
Let the number of text messages that makes their bill equal be x
Jorge will have a bill of = 50 + x(1) = 50 + x
Jillian will have a bill of = 72 + 0.12(x) = 72 + 0.12x
Since their bills will now be equal, we equate both
50 + x = 72 + 0.12x
72-50 = x-0.12x
22 = 0.88x
x = 22/0.88
x = 25 texts

Plug 3 into 5x+53 to find the angle.
5(3)+53=15+53=68.
Since 5x+53 and Z are on the same line, that means, when added together, they equal 180 degrees. Subtract 68 from 180.
z=112

Tigers, 25.
O B. The median for the Bulldogs, 80, is more than the median for the
Tigers, 65.
O C. The interquartile range (IQR) for the Bulldogs, 20, is less than the
IQR for the Tigers, 25.
D. The interquartile ranges (IQRs) for the Bulldogs and Tigers are
both 55.
Answer:
C. The interquartile range (IQR) for the Bulldogs, 20, is less than the
IQR for the Tigers, 25.
Step-by-step explanation:
When describing the spread of a given data set in a box plot using the five-number summary, the measure that is of utmost important is the range or the interquartile range.
The range is the difference between the max and the min.
The interquartile range is the difference between Q3 and Q1.
Therefore, considering the options given:
=>Option A is incorrect because the range for bull dog is 50 (105 - 55), while the range for Tigers is 55 (110 - 55).
=>Median cannot be used for describing spread, so option B is not the most appropriate comparison of the spreads.
=>Option C is correct and the most appropriate because the interquartile range of bulldogs is 20 (90 - 70), which is less than the IQR of Tigers which is 25 (85 - 60).
=>Option D is incorrect.

Answer:
the answer is [tex]\frac{13}{12}[/tex] or 1 [tex]\frac{1}{12}[/tex]
Step-by-step explanation:
First, you have to make all the denominators the same, which is the least common multiple of the 3 numbers, (6, 3, and 4). That would be 12.
So you change all the denominators to 12, keeping in mind that whatever you multiply the denominator by, you MUST multiply by the numerator.
You will end up with 2/12+8/12+3/12. Adding those together you get 13/12, or written as a mixed number, 1 [tex]\frac{1}{12}[/tex]
