Answer:
a = $80.3
b = $80
c = 4
d = 16
e = 4
f = 88
g = $132
h = 33%
i = 6
j = 30
k = 21
l = $90
m = $36
o = 21/50
p = 105
q = 7
r = 8 cm
s = 2.4
t = 4
u = 400cm
v = $280
Step-by-step Explanation:
==>Increasing $72 by 10% to get a
a = 110% of $72 = 110% × $73
a = 1.1 × 73
a = $80.3
==>a ($80.3) rounded to the nearest 10 to find b = $80
b = $80
==>Writing b (80) as the product of its primes I.e.
[tex]b = 2^{c} * 5[/tex]
Thus, 80 = 2⁴ * 5
c = 4
==>Calculating c² = d
d = 4² = 16
d = 16
==> ²/8 of d = e
e = ²/8 × 16
e = 2 × 2
e = 4
==> e% of 2200 = f
f = 4% × 2200
f = 0.04 × 2200
f = 88
==>Converting £f to $ = g
If £1 = $1.5,
£88 = $g
1 × g = 1.5 × 88
g = $132
==> Converting [tex]\frac{g}{400}[/tex] into % = h%
h = 132÷400 ×100
h = 0.33 × 100
h = 33%
==> √(h + 3) = i
i = √(33 + 3)
i = √36
i = 6
==> i × (3 + 2) = j
j = 6 × (3 + 2)
j = 6 × 5
j = 30
==> j% of 70 = k
k = j% × 70
k = 30% × 70
k = 0.3 × 70
k = 21
==> If k bottles = $63, 30 bottles = $l
21 bottles = $63
30 bottles = $l
21 × l = 63 × 30
21l = 1,890
l = 1,890/21
l = $90
==>If Tim and Mike (m) shares $90 in the ratio 3:2, Mike (m) would receive thus:
⅖ × $90 = m
m = 0.4 × 90
m = $36
==> √m + m = n
n = √36 + 36
n = 6 + 36
n = 42
==>Converting n% to fraction = o
Thus, o = 42/100
o = 21/50
==> o of 250 = p
p = 21/50 × 250
p = (21 × 250)/50
p = 21 × 5
p = 105
==> expressing p as a product of its primes i.e. p = 3 × 5 × q
105 = 3 × 5 × 7
Therefore, q = 7
==> Given a rectangle with dimensions of q cm and r cm, with an area of 56cm². Let's find r.
Area of rectangle = length × width = q × r
Area = 56 cm²
q = 7 cm
r = ?
56 = 7 × r
56/7 = r
8 = r
r = 8 cm
==> r × 0.3 = s
s = 8 × 0.3
s = 2.4
==> s ÷ 0.6 = t
t = 2.4 ÷ 0.6
t = 4
==> If t is in meters, converting t to cm will give us u
Since 1m = 100cm
4m = u cm
1 × u = 100 × 4
u = 400cm
==> Vikki (v) and John shares $u in the ratio 7:3. Thus, Vikki (v) would receive the following:
v = ⁷/10 × $400
v = 0.7 × 400
v = $280

determine if each polygons are similar, if so, write the similarity statement and the similarity ratio. if not explain why.
Answers
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.

Answers
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.

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?
Answers
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

Answers
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.

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.
Answers
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

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?
Answers
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

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

To work out X you can find the missing angle by doing;
[tex]180 - (90 + 18) = 72[/tex]

The net amount the salesperson will receive is:
Answers
Answer: $49,950
Step-by-step explanation:
Given Data:
Land sold = 300acre
Cost of land = $1200/acre
Commission schedule = 5% on first $200,000, 3.5% on next $50,000 and 2% on the balance.
10% gross commission must be paid to the agent.
Therefore
1. Total amount generated by the agent
= Cost/acre * acre sold
= $1200 * 300
= $360,000
10% gross commission receivable by the agent
= 0.1 * $360,000
= $36,000
5% receivable for first $200,000
= 0.05 * $200,000
= $10,000
3.5% receivable on next $50,000
= 0.035 * $50,000
= $1,750
2% receivable on remaining balance
= 0.02 * $110,000
= $2,200
Net amount receivable by the salesperson
= $36,000 + $10,000 + $1,750 +$2,200
= $49,950

Answers
Answer:
x = 5, AB = 5 inches, BC = 15 inches
Step-by-step explanation:
The segment addition postulate states that for line AC having point B between point A and point C, the distances between the point satisfy the equation:
AB + BC = AC
Given that AB = x and BC = 3x, also AC = 20 inches
AB + BC = AC
x + 3x = 20
4x = 20
Dividing through by 4:
4x/4 = 20/4
x = 5
Therefore AB = x = 5 inches, BC = 3x = 3 * 5 = 15 inches
