Finding the size of a billboard on side of road with unknown number or variable

Answers

Answer 1

Answer: Let's say the number is 5. 5 represents w or width. If the rule is w*8=h, then we just use 5*8, because the h is 8*w, which is 5. Follow this rule to solve these types of problems. Hope this helped!

You don't have to go any further than 2 itself.

All of the even numbers that are not multiples of 8 are counterexamples.

Allentown got 2 feet less than twice the amount of snow Georgetown got . Allentown got 3 feet more snow than Georgetown. How many feet of snow dis Allentown(x) and Georgetown (y) each get

Answers

Answer:

Allentown(x) got 8 feet of snow and Georgetown(y) got 3 feet of snow

Step-by-step explanation:

Allentown got 2 feet less than twice the amount of snow Georgetown got . Allentown got 3 feet more snow than Georgetown.

Allentown = x and Georgetown=y

To solve this we need to represent this information mathematically;

'Allentown got 2 feet less than twice the amount of snow Georgetown got' can be written mathematically as; x = 2y - 2

and

'Allentown got 3 feet more snow than Georgetown' can be mathematically written as x = y + 3

x= 2y - 2 ----------------------(1)

x = y + 3 --------------------------(2)

Subtract equation (2) from equation (1)

[ x-x=0 2y-y = y -2-3=-5]

0 = y - 5

To get the value of y, add 5 to both-side of the equation

0+ 5 = y-5+5

5=y

y=5

Substitute y=5 into equation (2)

x = y+3

x=5+3

x=8

Therefore Allentown(x) got 8 feet of snow and Georgetown(y) got 3 feet of snow

x=2y-2

x=y+3

Substitute the second equation into the first

y+3=2y-2

solve for y

y=5

plug into original

x=y+3=5+3=8 or x=2(5)-2=8

Allentown got 8 ft of snow, Georgetown got 5 ft of snow.

find the area of a regular hexagon with an apothem 10.4 yards long and a side 12 yards long. round your answer to the nearest tenth. show all your work

Answers

The answer is 374.4 yards.

There are 2 ways to calculate the area of a a regular hexagon.
It is given:
apothem: b = 10.4 yards
side: a = 12 yards

1. The direct way is to use the formula for the regular hexagon without using an apothem:
$A= (3 √(3) )/(2) a^(2)$
where
A - the area of the hexagon
a - the side of the hexagon

Therefore:
$A= (3 √(3) )/(2) 12^(2)$
$A= (3 √(3) )/(2) 144$
$A= 374.4$

2. The indirect way is to sketch the hexagon with 3 diagonals and create 6 triangles. Then, it is necessary to calculate the area of one triangle and multiply it by 6. In this triangle, apothem is actually the height.
The area of the hexagon is:
A = 6 · A₁
where:
A - the area of the hexagon,
A₁ - the area of the triangle

$A_(1)= (a*h)/(2)$

where
h - height of the triangle.

Since apothem (b) of the hexagon is the height (h) of the triangle, then:
$A_(1)= (a*h)/(2)$
$A_(1)= (12*10.4)/(2)$
$A_(1)= 62.4$

Thus, the area of one triangle is 62.4 yards.

To calculate the area of the hexagon, we will multiply it by 6:
A = 6 · A₁
A = 6 · 62.4
A = 374.4 yards

In both cases, the result is 374.4 yards.The answer is
