Answer:

23.78 cm

Step-by-step explanation:

Since, We know that,

In a right angle triangle,

cos \theta=\frac{B}{H}

Where, B represents base adjacent to \theta

H represents the hypotenuse adjacent to \theta

Thus, by the given diagram,

cos 18^{\circ}=\frac{x}{25}

\implies x = 25\times cos 18^{\circ}=23.7764129074\approx 23.78\text{ cm}

Hence, Last option is correct.

Un jardín rectangular de 50 cm de largo por 34 m de ancho está rodeado por un camino de arena uniforme.Halla la anchura de dicho
Anastasy [175]

Answer:

5.85 m

Step-by-step explanation:

The width of the sand road can be calculated knowing its area and the dimensions of the rectangular garden as follows:

A_{g} = a.b

<u>Where:</u>

Ag: is the area of the rectangular garden

a: is the length of the rectangular garden = 50 cm = 0.5 m

b: is the width of the rectangular garden = 34 m

A_{s} = 540 m^{2}

<u>Where</u>:

As: is the area of the sand road

The relation between the area of the sand road and the area of the rectangular garden is the following:

A_{s} + A_{g} = (a+2x)*(b+2x)

540 m^{2} + 0.5m*34m = ab + 2ax + 2bx + 4x^{2}

557 m^{2} = ab + 2x(a + b) + 4x^{2}

557 m^{2} - 17m^{2} - 2x(34.5 m) - 4x^{2} = 0

540 - 69x - 4x^{2} = 0                              

By solving the above equation for x we have two solutions:

x₁ = -23.10 m

x₂ = 5.85 m

Taking the positive value, we have that the width of the sand road is 5.85 m.

I hope it helps you!

How does the value of 874.12 change if the decimal point is moved two places to the left?
Rashid [163]

Answer:

C

Step-by-step explanation:

When you move the decimal either to the right or the left, you change the value. To divide any number by 10, move the decimal point one place to the left. For example:  

0.7

7

70

700

7,000

So, for any decimal, when you move the decimal point one place to the right, you multiply that number by 10.

Is this equation linear: 2y=x+x+1
Makovka662 [10]

An equation between two variables that gives a straight line when plotted on a graph.

2y = x+ x+ 1

2y = 2x + 1

y = (2x+ 1) /2

y = x + 1/2

According to the graph, this equation is linear

Maria designs and sells bowling uniforms. She charges a design fee of $8 for a custom bowling shirt, and sells each shirt for $2
GarryVolchara [31]

Answer:

y = 25x + 8

Step-by-step explanation:

The slope intercept equation has a standard form of;

y = mx + c

Now, we are told that She charges a design fee of $8 for a custom bowling shirt, and sells each shirt for $25 dollars.

And that y represents the total cost and x represents the number of bowling shirts.

Now, since x represents the number of bowling shirts, the cost of x bowling shirts is = 25x

Also, since design fee is $8, it means that total cost = 25x + 8

Writing this in slope intercept form;

y = 25x + 8
