Answer:

6. 12.5 cm

7. 0.7241

Step-by-step explanation:

6.

You have 2 right triangles. You can use the Pythagorean theorem for each one.

a^2 + b^2 = c^2

Let y = length of vertical side between triangles.

Left triangle:

5^2 + y^2 = 13^2

25 + y^2 = 169

y^2 = 144

y = 12

Right triangle:

3.5^2 + 12^2 = x^2

12.25 + 144 = x^2

x^2 = 156.25

x = 12.5

Answer: x  12.5 cm

For <X, 2.0 ft is adj leg. 2.9 ft is hyp.

cos X = 2.0/2.9 = 0.6897

X = cos^1 0.6897 = 46.397 deg

sin X = sin 46.397 deg = 0.7241

Answer:

x = 0   or  x = -4

Step-by-step explanation:

Solve: 6x² +24x = 0

First you can factor this binomial.

6x² +24x = 6x (x + 4) = 0

so  x = 0  or  x + 4 = 0

x = 0   or  x = -4

Answer:

The answer is 5/18

Step-by-step explanation:

The area of a rectangle with side lengths of 5/12 foot and 2/3 foot is 5/18 square feet and this can be determined by using the formula of the area of a rectangle.

Given :

Lengths of 5/12 foot and 2/3 foot.

The area of the rectangle is given by the formula:

A = W [tex]\times[/tex] L

where A represents the area of the rectangle, W represents the width of the rectangle, and L is the length of the rectangle.

So, the area of a rectangle with side lengths of 5/12 foot and 2/3 foot is given by:

[tex]\rm A = \dfrac{5}{12}\times \dfrac{2}{3}[/tex]

Further, simplify the above expression

[tex]\rm Area = \dfrac{10}{36}[/tex]

[tex]\rm Area = \dfrac{5}{18}[/tex]

The area of a rectangle with side lengths of 5/12 foot and 2/3 foot is 5/18 square feet.

80/89

Step-by-step explanation:

This is the real answer!! No tricks

The ratio to represent the cosine of ∠B is,

⇒ 80 : 89

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that;

In ΔBCD,

The measure of ∠D=90°, CB = 89, BD = 80, and DC = 39.

Now, We know that;

⇒ cos θ = Base / Hypotenuse

Her, By the given information, we get;

⇒ cos B = Base / Hypotenuse

⇒ cos B = BD / CB

⇒ cos B = 80 / 89

Thus, The ratio to represent the cosine of ∠B is,

⇒ 80 : 89

The average change in depth is 5 feet/ second.

It is required to find the average change in depth per second.

Numerical measure of a line's inclination relative to the horizontal. In analytic geometry, the slope of any line, ray, or line segment is the ratio of the vertical to the horizontal distance between any two points on it.

Step-by-step explanation:

As we know , hexagon has six sides .

so ,

We will divide the number of sides by the total perimeter to obtain the length of one side :

_____________________

Hexagon = 6 sides .

Length of one side of hexagon would be = 84/6

=> 14 cm

Answer:

14 cm

Step-by-step explanation:

The perimeter of a regular hexagon is 84 cm. (Given)

Here,

Hexagon = 6 sides

Now,

= 84 ÷ 6

= 14 cm

Thus, the length of one side is 14 cm

Answer:

1/3 = 0.3333 = 33.33%

Step-by-step explanation:

In the six-sided die we have 6 possible values, from 1 to 6.

To roll a number less than 5, the options are: 1, 2, 3 or 4.

We have 4 options, so the probability is P = 4/6 = 2/3

To find the complement of this probability, we just need to calculate 1 minus the probability, so we have that:

complement = 1 - P = 1 - (2/3) = 1/3 = 0.3333 = 33.33%

(We could also find the probability of rolling 5 or 6, which is the complement of rolling less than 5)

In the parenthesis with x it up or down on the y axis, and then after the function is what where after or before the origin the line starts on the x-axis.

Answer:

[tex] f(x) = g(x)[/tex]

[tex] 200 +0.075 x= 233 +0.06 x[/tex]

We can subtract from both sides 0.06x and we got:

[tex] 0.075 x-0.06x +200 = 233[/tex]

And now we can subtract 200 from both sides we got:

[tex] 0.015 x = 33[/tex]

And dividing both sides by 0.015 we got:

[tex] x = \frac{33}{0.015}= 2200[/tex]

And then the final anwer would be x =2200

Step-by-step explanation:

For this case we have the following function for the total sales of Lucy is given by:

[tex] g(x) = 200 +0.075 x[/tex]

And the function for the total sales of Zachary is given by:

[tex] f(x) =233 +0.06 x[/tex]

And we want to determine the value of x, in dollars, that will make their weekly pay the same, so we can set equal the two functions:

[tex] f(x) = g(x)[/tex]

[tex] 200 +0.075 x= 233 +0.06 x[/tex]

We can subtract from both sides 0.06x  and we got:

[tex] 0.075 x-0.06x +200 = 233[/tex]

And now we can subtract 200 from both sides we got:

[tex] 0.015 x = 33[/tex]

And dividing both sides by 0.015 we got:

[tex] x = \frac{33}{0.015}= 2200[/tex]

And then the final anwer would be x =2200
