Phil wants to fence off his rectangular yard. If the yard is 65 feet by 80 feet, and fencing costs $6 per foot, how much will it cost Phil to fence the yard?

Answer:

Step-by-step explanation:

3y = 5x -1

y = (5/3)x - ⅓

Slope of line is 5/3.

Slope of any parallel to the line is also 5/3.

Answer:

1) (f+g ) x = (x²-4)+ (x+2) = x²+ x –2

2) (f - g ) x = (x²-4) – (x+2) = (x²-4)+ ( -x - 2) = x²–x–6

3) (f × g ) x = (x²-4)(x+2) = x³+2x²– 4x – 8

4) (f / g) x = (x²-4) / (x+2) = x – 2

5) ( f + g ) 4 = (x²-4)+ (x+2) = ((4²)-4)+ (4+2) = ( 16–4) + (6) = 12+6 = 18

Answer:

17.23

Step-by-step explanation:

Find the cost of the cupcakes

8* 1.59= 12.72

Find the cost of the pies

5*5.99 =29.95

Subtract the cost of the cupcakes from the pies

29.95-12.72=17.23

Answer:

Money spent more on pies than cupcakes = $17.23

Step-by-step explanation:

1 cupcake = $ 1.59

8 cupcakes = 8 * $ 1.59

8 cupcakes = $12.72

1 pie = $5.99

5 pies = 5 * $5.99

5 pies = $29.95

Money spent more on pies than cupcakes = Pies - Cupcakes

Money spent more on pies than cupcakes = $29.95 - $12.72

Money spent more on pies than cupcakes = $17.23

Answer:

  (a)  $3.72

Step-by-step explanation:

The interest is found using the formula ...

  I = Prt

where P is the principal invested at rate r for t years. 3 months is 1/4 year, so the interest is ...

  I = $425×0.035×1/4 ≈ $3.72

Yousef earns $3.72 after 3 months.

The value of product will be;

⇒ 16.926

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

The expression is,

⇒ 1.3 (- 3.1) (4.2)

Now,

Since, The expression is,

⇒ 1.3 (- 3.1) (4.2)

After product, we get;

⇒ 1.3 × (- 3.1) × (4.2)

⇒ 4.03 × 4.2

⇒ 16.926

Thus, The value is = 16.926

Answer:

 no

Step-by-step explanation:

Using only a straightedge, you cannot measure distance, so cannot ensure that any two distances are the same.

__

The points of interest are on the perpendicular bisector of AB, which can be constructed using a compass and straightedge. The straightedge alone is insufficient.

Angle B=90 degrees

BA^C= 40 degrees

Step-by-step explanation:

Angle B=90 degrees (right angle =90 degrees)

90+50+BA^C=180

140+BA^C      =180

           BA^C=180-140

          BA^C= 40 degrees

Answer:

Devon is 50 and Sydney is 25

Step-by-step explanation:

We know that d + s = 75 and that Devon is two times Sydney's age. This can be represented by 2s + s = 75 (keep in mind that 2s = d). Simplify the equation.

3s = 75

s = 25

Now we can substitute this in the original equation.

d + 25 = 75

d = 50

Best of Luck~

Answer: Sydney=25 Devon=50

Step-by-step explanation:

Sydney's age is represented by x and since Devon is 2 times older (his/her) age would be represented as 2x. So added together would be 3x. So 3x=75. 75/3=25. So x=25 meaning that Sydney is 25 and Devons age is 50 as 25x2=50.

Answer:

x=4

Step-by-step explanation:

Simplifying

-1(7 + -4x) = 9

(7 * -1 + -4x * -1) = 9

(-7 + 4x) = 9

Solving

-7 + 4x = 9

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '7' to each side of the equation.

-7 + 7 + 4x = 9 + 7

Combine like terms: -7 + 7 = 0

0 + 4x = 9 + 7

4x = 9 + 7

Combine like terms: 9 + 7 = 16

4x = 16

Divide each side by '4'.

x = 4

Answer:

x = 4

Step-by-step explanation:

-(7 - 4x) = 9             (Given)

-7 + 4x = 9              (Distributed)

-7 + 4x + 7 = 9 + 7  (Add 7 on both sides)

4x = 16                    (Simplify)

4x/4 = 16/4             (Divide 4 on both sides)

x = 4                       (Simplify)

Answer:

x = –2/3 or –20/9

Step-by-step explanation:

(9x+13)² = 49

Finding the square root of both sides

9x+13 = √49

9x+13 = ±7

Subtracting 13 from both sides

9x = 7 – 13 or 9x = -7 –13

9x = –6 or 9x = –20

Divide both sides by 9

x = –6/9 or x = –20/9

Simplifying

x = – 2/3 or x = –20/9

Answer:

  D. m∠C=63, b=28.1, c=25.1

Step-by-step explanation:

The angle sum relation tells you ...

  C = 180° -23° -94° = 63°

The law of sines tells you ...

  b/sin(B) = a/sin(A)

  b = sin(B)·a/sin(A) = sin(94°)·11/sin(23°) ≈ 28.084 ≈ 28.1

Similarly, ...

  c = sin(C)·11/sin(23°) = sin(63°)·28.15235 ≈ 25.084 ≈ 25.1

__

  C = 63, b = 28.1, c = 25.1

Answer:

3 hours

Step-by-step explanation:

You find the LCM between 20 and 15, which is 5. This means that Kim and Tom are both biking at 5 miles per hour, meaning that to determine how much time Tom takes, you would do 15/5, which is 3 hours.

Time taken by Tom to get office is 3 hour

Given information:

Distance of office from Kim house = 20 km

Distance of office from Tom house = 15 km

Kim take 1 hour more

Find;

Time taken by Tom to get office

Computation:

Assume;

Time taken by Tom = a hour

So,

Time taken by Kim = (a + 1) hour

[tex]Speed = \frac{Distance}{Time}[/tex]

So,

[tex]\frac{20}{(a + 1)}=\frac{15}{a} \\\\20a = 15a + 15\\\\20a - 15a = 15\\\\5a = 15\\\\a = 3[/tex]

So,

Time taken by Tom = 3 hour
