Answer: The total cost would be $780.00
The expression for the total cost of fencing is $52x , where x is a variable representing the number of feet in one section.
What is an expression in one variable?An expression in one variable is a statement formed by the using constants and an unknown variables and mathematical operators but sign is equal to is not used. Expression in one variable is linear if the power of the unknown variable is equal to one .
Given that number of feet in one fence section be x
No of feet in 8 such fence section = 8x
Given , Perimeter = 8 fence sections = 8x feet
Cost of fencing of one foot = $6.50
Cost of fencing 8x feet = 8x * 6.50
Therefore , the total cost of the fencing can be given by = 8x*6.50
= $ 52 x
Thus, the expression for the total cost of fencing is $52x

Jerome found the lengths of each side of triangle QRS as shown, but did not simplify his answers. Simplify the lengths of each side to answer the question. Which statement about triangle QRS is true?
a. Triangle QRS is an equilateral triangle because QR = RS.
b. Triangle QRS is an isosceles triangle because QR = QS.
c. Triangle QRS is a scalene triangle because all sides have different lengths.
d. Triangle QRS is an isosceles triangle because QR = RS.
Answer:
D. Triangle QRS is an isosceles triangle because QR = RS.
Step-by-step explanation:
Find the length of each side of the triangle using the formula for calculating the distance between two points.
D = √(x2-x1)²+(y2-y1)²
For side RS
R(0,0) and S(5, -3.322)
RS = √(5-0)²+(-3.322-0)²
RS = √25+11.035684
RS = √36.035684
RS = 6.0029
For side RQ
R(0,0) and Q(-3, -5.2)
RQ = √(-3-0)²+(-5.2-0)²
RQ = √9+27.04
RQ = √36.04
RQ = 6.0033
For side QS
Q(-3,-5.2) and S(5, -3.322)
QS = √(5+3)²+(-3.322+5.2)²
QS = √64+3.526884
QS = √67.526884
QS = 8.22
From the calculation it can be seen that RS=QR
Since the two sides f the triangle are equal, hence the triangle is an isosceles triangle. An isosceles triangle is a triangle that has two of its sides equal

Answer:
Total interest = A - P = $2,223.00
Total amount = $10,023.00
Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 9.5%/100 = 0.095 per year.
Solving our equation:
A = 7800(1 + (0.095 × 3)) = 10023
A = $10,023.00
The total amount accrued, principal plus interest, from simple interest on a principal of $7,800.00 at a rate of 9.5% per year for 3 years is $10,023.00.

Hanna says you cannot represent the fraction 1/4 on the number line.
Answer:
The answer is D; Hanna is not correct,. The fraction 1/4 is equal to 2/8, so you can graph it on the second tick mark to the right of zero.
Step-by-step explanation:
Because the number line is broken up into 8 parts, the points on the graph are, 1/8, 2/8, 3/8, 4/8, 5/8, 6/8, 7/8, 8/8 (also known as one)
1/4 = 2/8. We know this because if we multiply 1/4 by 2, we get 2/8.
So, because 2/8 is the same as 1/4, we know that Hanna is not correct, and that you can graph 1/4 on this number line, because it is the same as 2/8.
I hope that this helps :)

The Sum Of Two Numbers Is 18 And Their Difference Is 4
Answer:
The two numbers are 7 and 11.
[711? Is this an ad? ← :)]
Step-by-step explanation:
Let A and B stand for the two numbers.
We are told that:
1) A+B=18, and
2) A-B=4
Take the first expression and rearrange to isolate A:
A+B=18
A=18-B
Use this in the second expression:
(18-B)-B=4
-2B = -14
B = 7
From (1) we find A:
A+B=18
A+7=18
A= 11
If A=11, then B=7 (from A+B=18)
CHECK:
Does A+B=18?
11 + 7 = 18? YES
Does A-B=4?
11 - 7 = 4? YES

Answer:
p = 45 - 2.5f
Step-by-step explanation:
5f + 2p = 90
just manipulate the equation, treat it like a regular algebra equation and solve for p by inverse operations and simplifying
5f + 2p = 90
-5f -5f
2p = 90 - 5f
/2 /2
p = [tex]\frac{90 -5f}{2}[/tex]
p = 45 - 2.5f

Find the measures of the sides of triangle DEF, then classify it by its sides. YOU MUST SHOW WORK TO GET CREDIT!
D(-2, 3), E(5, 5), F(-4, 10)
Answer:
FE = 10.30
ED = 7.62
FD = 7.28
Step-by-step explanation:
First, use coordinate system to draw a square that each angle of triangle reach the sides of the square, then use Pythagoras theory to find the length of the sides(c^2=a^2+b^2)
FE = root(9^2+5^2) = root(106) = 10.30
ED = root(3^2+7^2) = root(58) = 7.62
FD = root(2^2+7^2) = root(53) = 7.28
