Answer:
A(x) = x(200-x)
Step-by-step explanation:
400 feet of fencing to enclose a rectangular dog exercise pen means the perimeter of rectangle is 400 feet
If x is length and y is breadth. Perimeter is given by :
P = 2(x+y)
400 = 2(x+y)
⇒ (x+y) = 200 .....(1)
y = 200-x
Area of a rectangle is given by :
A = xy
A(x) = x(200-x)
Hence, the area as a function of length of rectangle is x(200-x).
3x+29>4(x+7)
how do I solve this and the answer is NOT x<8 the answer is supposed to be x<1 but I don't know how to get there.

A person standing 44 feet from a street light casts a shadow as shown. What is the height h of the street light? Assume the triangles
are similar.
Please help!!!
Answer:
a. 26 ft

8(k - 6) +58 = 2(4k + 5)
one solution
no solutions
infinite solutions
Answer:
infinite solutions
Step-by-step explanation:
Given
8(k - 6) + 58 = 2(4k + 5) ← distribute parenthesis on both sides
8k - 48 + 58 = 8k + 10 , that is
8k + 10 = 8k + 10
Since both sides are equal then any value of x will make the equation true.
There are an infinite number of solutions

What is the volume of the figure below, which is composed of two cubes with side lengths of 9 units?
A.
54 cubic units
B.
729 cubic units
C.
1,458 cubic units
D.
810 cubic units
Answer:
C. 1458 cubic units
Step-by-step explanation:
one cubes side length is 9. The only side that changes is the length since the size is doubled so instead of it 9 it would be 18.
V= L × W × H
= 18 × 9 × 9
= 1,458

Answer:
y = 1.37
Step-by-step explanation:
30y = 41.10
divide both sides of the equation by 30
30y/30 = 41.10/30
y = 41.10/30
y = 1.37

what is the vaule of x?
Answer:
-1
Step-by-step explanation:
all of them add up to 1
you have 6 pieces confirmed to be the value of 1
if 5 blocks so if they all equal-1 then you'd have to add 6 + (-5) then you'd get 1

The table and statement show the hours worked and the amounts paid for two workers.
A table labeled Worker A Earnings. It contains a row for Hours worked with the amounts 7, 12, 21, 33, 40, and a row for Amount paid with the amounts 87.50, 150, 262.50, 412.50, and 500.
Worker B earns $11.25 per hour
Which statements about the rates of pay for the two workers are true?
Select each correct answer.
Worker A earns less per hour than Worker B.
Worker B earns more after 10 hours than worker A.
Worker A earns $12.50 per hour.
After 20 hours of work, Worker A earns more than Worker B.
1st statement is correct
2nd statement is correct.
finding the average hours worker A does and then the average amount paid i got
average hrs = 22.6 hrs and average amount paid= $250
so comparing them to one hr i got the amount paid to worker A in one hr which is $1.11
so compare to worker B earnings and find the true statements

Representing each situation by translating it to algebraic expression.
- a motorcycle driver travels 15kph faster than a bicycle rider. the motorcycle driver covers 60km in two hours less than the time it takes the bicycle rider to travel the same distance.
Answer:
Kindly check explanation
Step-by-step explanation:
Given that :
Motorcycle driver travels 15kph faster than a bicycle rider
Motorcycle covers 60km in 2 hours less than the time it takes bicycle rider to travel the same distance ;
Let bicycle rider's speed = r kph
Motorcycle driver's speed = (15 + r) kph
TIME it takes bicycle rider to cover a distance of 60km = t hours
TIME it takes motorcycle driver to cover a distance of 60km = (t - 2) hours

) You owe $135. on your credit card. You make a $45. payment and then purchase $97 worth of clothes at Kohl’s. What is the integer that represents the balance owed on the credit card?
Answer:
$ 187
Step-by-step explanation:
Assuming the credit card is for Kohl's,
You make a 45 dollar payment: your debt goes down by 45
You make a 97 dollar purchase: your debt goes up by 97
135-45+97
Your current debt is 187 dollars. Not a nice way to live if you ask me!
Given collinear points E, F and G such that point F is the midpoint of segment EG. Find the new length of EG given that EF =5x+9 and FG = 3x +17
Answer:
The length of EG is 58 units
Step-by-step explanation:
The midpoint of a segment divides it into two equal part
Let us use this rule to solve our question
∵ E, F, and G are collinear points
∵ Point F is the midpoint of segment EG
→ That means F divides EG into 2 equal segments EF and FG
∴ EF = FG
∵ EF = 5x + 9
∵ FG = 3x + 17
→ Equate them
∴ 5x + 9 = 3x + 17
→ Subtract 3x from both sides
∵ 5x - 3x + 9 = 3x - 3x + 17
∴ 2x + 9 = 17
→ Subtract 9 from both sides
∴ 2x + 9 - 9 = 17 - 9
∴ 2x = 8
→ Divide both sides by 2 to find x
∵ [tex]\frac{2x}{2}=\frac{8}{2}[/tex]
∴ x = 4
→ Substitute x by 4 in EF and FG to find their lengths
∵ EF = 5(4) + 9 = 20 + 9 = 29
∵ FG = 3(4) + 17 = 12 = 17 = 29
∵ EG = EF + FG
∴ EG = 29 + 29 = 58
∴ The length of EG is 58 units
