Q8 Q2.) What are the​ lot's dimensions?
Triss [41]
Equation for perimeter is 2L +2W

perimeter of the lot is 390 ft

 so we have 390 = 2L +2w

divide all terms by 2:

195 = L + W

rewrite this as L = 195-W  ( eq.1)

 cost of fence for the length = 36 per foot so we have 36L
cost of fence for width = 6 per foot so we have 6W

the fence was 1 length and 2 sides
 so we have 36l + 6w +6w = total cost

total cost is 4980

so we have 4980 = 36L + 6w +6w

combine like terms:

4980 = 36L +12w

replace L with eq1 from above:

4980 = 36(195-w) +12w

distribute:

4980 = 7020 -36w +12w

combine like terms:

4980 = 7020-24w

subtract 7020 from both sides:

-2040 = -24w
 divide both sides by -24:

-2040 / -24 = 85
width = 85 feet

using eq1 L = 195 - 85

Length = 110 feet

lond = 110 feet
 short = 85 feet

A circle has a circumference of 120 meters. What is the measure of its radius? Round to the nearest tenth.
WITCHER [35]

Answer: The radius of circle is 19.1 meters.

Explanation:

Since we have given that

Circumference of a circle = 120 meters

As we know the formula for "Circumference of circle" i.e.

C=2\pi r\\\\120=2\times \frac{22}{7}\times r\\\\\frac{120}{2}=\frac{22}{7}r\\\\60\times 7=22\times r\\\\420=22\times r\\\\\frac{420}{22}=r\\\\r=19.1\ meters

Hence, the radius of circle is 19.1 meters.

PLEASE HELP !!!!!! I DONT UNDERSTAND SO PLEASE SOMONE AT LEAST HELP OR TRY!!!!.
erik [133]

Answer:

The first x = 4

The second x = 6.25

Step-by-step explanation:

For the first question. We need to make use of the midsegment theorem which says, if you have a trapezoid with base1 and base2, then the midsegment is given as:

(Base1 + Base 2)/2.

We are given Base 1 = 5x + 3 and Base 2 = 12x – 3 and the midsegment, JK = 34. To find x we have:

(5x + 3 + 12x – 3)/2 = 34

This gives: 17x/2 = 34.

Therefore, x = (34 x 2)/17 = 4. Thus, x = 4.

As for the second question, we have two diagonals of the rectangle, FH and JG. We are given that JG = 40. We know that the diagonals of the rectangle are equal, therefore FH = 40 as well.

We are told that M is the midpoint, meaning FM is half of the diagonal FH. Mathematically this can be written as:

FM = FH/2

Given that FM = 3.2x and FH = 40, we have:

3.2x = 40/2

3.2x = 20

x = 20/3.2

x = 6.25
