Mr. and Mrs. Samson are planning to build a fence around their garden. They are comparing the different measurements for their plans.
Plan A:
1.Posts are 4 ¼ feet in length
2. Post must be installed 7/8 feet below ground level.
Plan B:
1. Posts are 6 ¾ feet in length.
2. Posts must be installed 1 ½ feet below ground level.
1.What will be the height of the fence in plan A?
2. What will be the height of the fence in plan B?
3. Which fence will be taller and by how much?
4. Which plan would you recommend and why?
5. Mr. And Mrs. Samson decide to go with plan A and purchase the materials. Their total bill is $356.88. If they pay $220 in cash and charge the remainder, how much did they charge?
Answers
The relationship between the heights of the fence, the lengths, the distance below the ground level is an illustration of addition and subtraction.
The height of the fence is [tex]3\frac 38[/tex] in plan A and [tex]4\frac 34[/tex] in plan BThe fence in plan B is taller by [tex]2\frac{3}{4}[/tex] feet.The fence in plan B is recommended because: It is taller than the fence in plan A, and it goes below the ground level than plan AThey charge $136.88Plan A
[tex]Length = 4\frac 14[/tex]
[tex]Ground\ Level = \frac 78[/tex]
Plan B
[tex]Length = 6\frac 34[/tex]
[tex]Ground\ Level = 1\frac 12[/tex]
The height of the fence is calculated by subtracting the length below ground level from the length of the fence. So, we have:
[tex]Plan\ A = 4\frac 14 - \frac 78[/tex] [tex]Plan\ B = 6\frac 34 - 1\frac 12[/tex]
[tex]Plan\ A = \frac{17}{4} - \frac 78[/tex] [tex]Plan\ B = \frac{25}{4} - \frac 32[/tex]
Take LCM
[tex]Plan\ A = \frac{17\times 2 - 7}{8}[/tex] [tex]Plan\ B = \frac{25 - 3\times 2}{4}[/tex]
[tex]Plan\ A = \frac{34 - 7}{8}[/tex] [tex]Plan\ B = \frac{25-6}{4}[/tex]
[tex]Plan\ A = \frac{27}{8}[/tex] [tex]Plan\ B = \frac{19}{4}[/tex]
[tex]Plan\ A = 3\frac{3}{8}[/tex] [tex]Plan\ B = 4\frac{3}{4}[/tex]
Hence, the height of fence is [tex]3\frac 38[/tex] in plan A and [tex]4\frac 34[/tex] in plan B
The fence in plan B is taller because [tex]4\frac 34[/tex] is greater than [tex]3\frac 38[/tex]
The difference (d) in the heights is:
[tex]d = 4\frac 34 - 3\frac 38[/tex]
[tex]d = \frac{19}{4} - \frac{27}{8}[/tex]
Take LCM
[tex]d = \frac{19 \times 2 - 27}{4}[/tex]
[tex]d = \frac{38 - 27}{4}[/tex]
[tex]d = \frac{11}{4}[/tex]
[tex]d = 2\frac{3}{4}[/tex]
Fence in plan B is taller by [tex]2\frac{3}{4}[/tex] feet.
I will recommend the fence in plan B because:
It is taller than the fence in plan AIt goes below the ground level than plan AFor (5), we have:
[tex]Total = \$356.88[/tex]
[tex]Cash = \$220[/tex]
The remainder is the difference in the total amount and the amount they paid:
[tex]Charge = Total - Cash[/tex]
[tex]Charge = \$356.88 - \$220[/tex]
[tex]Charge = \$136.88[/tex]
Hence, they charge $136.88

how many inches is in 140 feet?
Answers
Hey there!
The formula for feet to inches is to simply multiply the length value by 12.
So, multiply 140 by 12.
I believe your answer would be 1680 inches.
Hope this helps!
Have a great day!
Answer:
140 feet is 1680 inches. Don't forget to put your units in; your teacher may dock off points for forgetting to put in the unit.
Step-by-step explanation:
A foot is 12 inches, so you must multiply 140 by 12.

A bag contains 8 red marbles, 4 blue marbles and 7 green marbles. If three marbles
are drawn out of the bag, what is the exact probability that all three marbles drawn
will be red?
Answers
Based on the way you stated the questions, I do not assume the red marble that was pulled first would be put back, so there’s only 18 marbles left to choose from and 7 of those are red. So on the second marble, you have 7/18 chance of pulling a red.
Again, since neither of the first two marbles were put back, you now have 17 marbles left and 6 of those are red. So you have a 6/17 chance of pulling a third red marble.
Multiply those together, 8/19 * 7/18 * 6/17 and you’ll have your answer.
Answer:
NO. OF RED =8
NO. OF BLUE=4
NO. OF GREEN=7
THEREFORE,TOTAL MARBLES=19
THEREFORE,PROBABILTY OF RED MARBLES=8/19.
find the measure of angle of ABF
Answers
Answer: m∠ABF = 120°
Concept:
Here, we need to know the idea of the corresponding angle theorem and linear pair postulate.
The corresponding angle theorem states that if a transversal cuts two parallel lines, their corresponding angles are congruent.
The linear pair postulate states that two angles that form a linear pair are supplementary.
Solve:
Given information
m∠ABF = m∠ABF = 2x + 3x
According to the corresponding angle theorem, ∠ABF is congruent to ∠BCI which is 2x + 4x.m∠BCH = 3x
Total angle = 180°
∠ABF and ∠BCH are linear pairs which means they form a supplementary angle.Given equation
m∠ABF + m∠BCH = Total Angle
Substitute values into the equation
2x + 4x + 3x = 180
Combine like terms
9x = 180
Divide 9 on both sides
9x / 9 = 180 / 9
x = 20
m∠ABF = 2x + 4x = 2 (20) + 4 (20) = 40 + 80 = 120°
Hope this helps!! :)

Answer:
m<RST = 32°
m<TSQ = 58°
Step-by-step explanation:
m<RST here, meaning the angle of the whole diagram is 90 degrees as you can see.
m<RSQ + m<TSQ = m<RST
15x — 43 + 8x + 18 = 90
23x — 25 = 90
+25 +25
---------------------------
23x = 115
/23 /23
----------------------------
x = 5
Now, plug this into the equation for m<RSQ and m<TSQ to find their values.
m<RSQ = 15x — 43
= 15x - 43
= 15(5) - 43
= 75 - 43
= 32
m<TSQ = 8x + 18
= 8x + 18
= 8(5) + 18
= 40 + 18
= 58
Now, check to see if our values are right or not.
15x — 43 + 8x + 18 = 90
15(5) — 43 + 8(5) + 18 = 90
75 - 43 + 40 + 18 = 90
32 + 40 + 18 = 90
90 = 90 CORRECT

Answers
Answer:
y = 3x - 25
Step-by-step explanation:
If the line is parallel, it will have the same slope. So, the line will also have a slope of 3.
Plug in the slope and given point into y = mx + b, and solve for b:
y = mx + b
2 = 3(9) + b
2 = 27 + b
-25 = b
Plug in the slope and y intercept into y = mx + b:
y = mx + b
y = 3x - 25
So, the equation of the line is y = 3x - 25
