------------------------

Perimeter would be the sum of all the sides so: (w+4) + w + (w+4) + w

Perimeter is 60 yards according to your problem so: (w+4) + w + (w+4) + w = 60 yds

1.Simplify/combine like terms:

w + 4 + w + w + 4 + w =

4w + 8 =

Now it's a 2-step algebra equation

4w + 8 = 60

2.Subtract 8 on both sides

4w = 56

3.Divide both sides by 4

w = 14

Answer:

Step-by-step explanation:

A parallelogram is a shape that has two sets of parallel. There are a number of examples of parallelogram including but not limited to, square, rectangle, rhombus etc

From the question, the answer is, the shape is a rectangle. This is because the question says that the shape has its adjacent angles congruent, this means that they are supplementary(i.e they add up to 180). A rectangle is the one who fits the perfect description

Answer:

Step-by-step explanation:

1. Use proportions and cross-multiply:

[tex]\frac{X mm }{37cm} =\frac{10 mm}{1cm} \\x = 37 * 10 = 370[/tex]

2. Use proportions and cross-multiply:

[tex]\frac{20 m}{X cm} =\frac{1 m}{100cm} \\x=20*100=2000[/tex]

3. Use proportions and cross-multiply:

[tex]\frac{34in}{Xmm} =\frac{1in}{25.4mm} \\x=34*25.4=863.6[/tex]

4. Use proportions and cross-multiply:

[tex]\frac{20m}{Xkm} =\frac{1m}{0.001km} \\x=20*0.001=0.02[/tex]

5. Use proportions and cross-multiply:

[tex]\frac{29 km}{Xm}=\frac{1 km}{1000m} \\x=29*1000=29000[/tex]

Answer:

The length of the ladder  = 6.5077 ft

Step-by-step explanation:

Given A ladder leans against the side of a house

Given the angle of elevation of the ladder is 68° when the bottom of the ladder is 16 ft from the side of the house

Let 'C' be the point of observation.

Given CA= 16 ft

 From right angle triangle

     x = 16 × cos 68°

    x = 16 × 0.4067

    x = 6.5077

  x = 6.5 ft

The length of the ladder = 6.5 ft

Answer:

39 feet.

Step-by-step explanation:

If a 6 foot pole cast 10 feet continue to mutiply 6 until you get to 60 and once you get to 60 half the 6 into 3 adding 3 feet.

Step-by-step explanation:

Answer:

D) 44

Step-by-step explanation:

The limit of the function k(x) as x approaches -15 from the right side is 44. Therefore, option D is correct.

Answer:

3(8-4x) < 6(x-5)

24-12x < 6x-30

24+30 < 6x+12x

54 < 18x

54\18 < x

3 < x

It means the ans is option no. b

Step-by-step explanation:

3(8-4x)<6(x-5)

24-12x<6x-30

-12x-6x<-30-24

-18x>-54

Divide both sides by -18

=x>3

Ans is B(second number line)

Answer:

True

Step-by-step explanation:

Answer:

Step-by-step explanation:

It is true!

Let's say we subtract 6 from both sides

-2x -6< 0                       Now Let's add 2x to both sides

-2x + 2x - 6 < 0 + 2x

- 6 < 2x                         We did so we would be dividing by a number greater than 0.                         Divide by + 2

-6/2 < 2x / 2

-3 < x                            Notice you still get the open end of the inequality sign closest to the x without changing the direction of the inequality.

Answer:

Option C

Step-by-step explanation:

Rational numbers are numbers of the form p/q, where p and q are integers and q not equal to zero.

Integers are number of the form p/q , where q = 1

Option A : 188 => integer and rational

Option  B: 13   =>  integer and rational

Option C :2/5  =>  rational but not integer ( because q = 5 and not 1 )

Option D : - 51 => integer and rational

Answer:

Step-by-step explanation:

As,

Integers includes whole numbers, and negative of the whole numbers.

And Rationals includes every fraction, Integers and negative fraction.

So,

188, -4, and 51 are both Integers and Rationals.

But,

Only 13 2/5 is a mixed fraction included only in rationals and not in Integers

Answer:

$16.03

Step-by-step explanation:

Two twenty dollars bills is forty dollars, so to find his change, subtract $23.97 from $40. This gives you $16.03.

The change should he receive if he gave the cashier two $20 bills is $16.03.

We have given that,

Satish bought a bicycle wheel for $23.97.

We have to determine the value of How much change should he receive if he gave the cashier two $20 bills.

Change is the money returned after paying for something with more money than it costs

Two twenty dollars bills is forty dollars, so to find his change, subtract $23.97 from $40.

This gives you $16.03.

Answer:

[tex]\cos(\theta)=\frac{4}{5}[/tex]

Step-by-step explanation:

Step 1:

Let us find the missing side. We know this is a right triangle, so we can use the pythagorean thereom to find the last side. Let us set 12 as variable a, 20 as variable c, and the unknown side as variable b.

[tex]a^2+b^2=c^2\\12^2_b^2=20^2\\b^2=400-144\\b^2=256\\b=\pm16[/tex]

We do know that a length can never be negative, so the side b would be 16.

Step 2:

According to SOHCAHTOA, cosine is utilizes the adjacent and hypotenuse of the given angle theta. Let us write the equation:

[tex]\cos(\theta)=\frac{adjacent}{hypotenuse} \\\\\cos(\theta)=\frac{16}{20} \\\\\cos(\theta)=\frac{4}{5}[/tex]

On a coordinate plane, an oval line crosses the y-axis 2 times and the x-axis two times.

Step-by-step explanation:

Vertical line test.

If you draw a vertical line, parallel to the y-axis and it crosses a line or shape twice, it is not a function.

On a coordinate plane, an oval line crosses the y-axis 2 times and the x-axis two times. The correct option is C.

A function is defined as the expression that set up the relationship between the dependent variable and independent variable. A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.

On taking the vertical line test it is observed that If you draw a vertical line, parallel to the y-axis and it crosses a line or shapes twice, it is not a function.

Therefore, on a coordinate plane, an oval line crosses the y-axis 2 times and the x-axis two times. The correct option is C.
