Answer:

[tex]\approx 26.16\:\mathrm{m}[/tex]

Step-by-step explanation:

Let [tex]h[/tex] be the height of the tree. In reference to the tree and bird, a right triangle is formed. We can write the following trig function for that right triangle:

[tex]\tan28^{\circ}=\frac{h}{15},\\h=15\tan28^{\circ},\\h\approx 7.98\:\mathrm{m}[/tex].

Now we can use this to find the hypotenuse of this triangle (the distance between the cat and the bird):

Let the distance between the cat and bird be [tex]k[/tex]. Then,

[tex]7.98^2+15^2=k^2,\\k\approx 16.99\:\mathrm{m}[/tex]. This is one side of the triangle that is formed by the cat, bird, and mouse.

The right triangle formed by the tree, cat, and mouse shares the height [tex]h[/tex] with the other right triangle, as we found earlier. Let [tex]l[/tex] represent the hypotenuse of this triangle or the distance between the cat and mouse. We then have the following trig function:

[tex]\sin 40^{\circ}=\frac{7.98}{l},\\l=\frac{7.98}{\sin40^{\circ}}\approx 12.41\:\mathrm{m}[/tex]. This is another side of the triangle that is formed by the cat, bird, and mouse.

The triangle that is formed by the cat, bird, and mouse has shares an angle of [tex]125^{\circ}[/tex] with the base of the auxiliary pyramid. The other angles, however, are not shared.

Since we have two sides and the angle between these two sides, we can use the Law of Cosines to find the other side (the distance between the mouse and bird). The Law of Cosines is given by:

[tex]m^2=k^2+l^2-2kl\cos M[/tex], where [tex]m[/tex] is the distance between the bird and the mouse and the other variables are defined above.

Plugging in values, we get:

[tex]m^2=16.99^2+12.41^2-2\cdot16.99\cdot12.41\cdot\cos 125^{\circ}[/tex]

Solving, we get:

[tex]m\approx \fbox{$26.16\:\mathrm{m}$}[/tex].

Answer:

i) the length is 10cm

ii) the perimeter is 36 cm

Step-by-step explanation:

i) We know that Area of a rectangle can be found by using the following formula...

A = l x w

(where A is area of the triangle, l is the length of the triangle, and w is the width of the rectangle).

From this we know that

l = A/w

[tex]l = 80cm^{2} / 8cm = 10cm[/tex]

ii) Now that we know both the length and the width we know we can find the perimeter by using the following formula...

P = 2(l + w)

[tex]P = 2(10cm+ 8cm )\\P = 20cm + 16cm\\P = 36cm[/tex]

Answer:

1. x-intercept = 3/-5 = -0.60000

 y-intercept = 3/1 = 3

2. x-intercept = 3/3 = 1

 y-intercept = 3/1 = 3

Step-by-step explanation:

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line  y-5x-3  = 0 and calculate its properties

When y = 0 the value of x is 3/-5 Our line therefore "cuts" the x-axis at x=-0.60000

Answer:

slope: 3/2, y-intercept: (0,1/2)

Step-by-step explanation:

Graph the line using the slope and y-intercept, or two points.

1,300 computers

Step-by-step explanation:

As, they are saying they sold 30% of the computers last month

And that 30% was 390

So, x = the total number of computers

30% of x = 390

30% = 30/100 and "of" represents multiplication

So 30/100 X x = 390

We will transpose everything

30x = 39000

x = 39000 ÷ 30 = 1,300

So 1,300 computers were sold

Answer:

Perimeter: 310 units

Step-by-step explanation:

If x=4 and y=5, then the measure of the lengths would be..

8y+19= 8(5)+19= 59

8x+64= 8(4)+64= 96

13y-6= 13(5)-6= 59

16x+32= 16(4)+32= 96

To check if all these measurements are congruent, we can see if they match up with the measure of their parallel line, which they do in this case because 59=59

96=96

To find the perimeter of any shape, we add all the side lengths together

59+59+96+96= 310

Hope I was able to help! Good Luck!

Answer:

Perimeter is 310 unis

Answer: 76

Step-by-step explanation: 104 + 76 = 180

We can find the slope by using the slope formula. Also know rise over run.

[tex] \large \bold{m = \frac{rise}{run} }[/tex]

[tex]m = \frac{2 - 0}{ - 2 - 2} \\ m = \frac{2}{ - 4} \\ m = - \frac{1}{2} [/tex]

From the slope-intercept y = mx+b.

[tex] \large \bold {m = slope } \\ \large \bold {b = y - intercept }[/tex]

[tex] \large \boxed { - \frac{1}{2} }[/tex]

Answer:

-1/2

Step-by-step explanation:

Going from (-2, 2) to (2, 0), x (the run) increases by 4 and y (the rise) decreases by 2.  Thus, the slope of this line is m = rise / run = -2/4 = -1/2.

Answer:

The total prize money for the competition is $1750

Step-by-step explanation:

Let us solve the question

→ The golf club runs a competition

∵ The total prize money is shared in the ratio 1st prize: 2nd prize = 9: 5

∵ The 1st prize is $500 more than the 2nd prize

∴ The difference between the 1st prize and the second prize = $500

→ Find the difference between the terms of the ratio

∴ The difference in the terms of the ratio = 9 - 5 = 4

→ By using the ratio method

→  1st   :   2nd   :   difference

→  9     :   5       :   4

→  x     :   y        :   500

→ By using the cross multiplication

∵ x × 4 = 9 × 500

∴ 4x = 4500

→ Divide both sides by 4 to find x

∴ x = 1125

∴ The 1st prize is $1125

∵ y × 4 = 5 × 500

∴ 4y = 2500

→ Divide both sides by 4

∴ y = 625

∴ The 2nd prize is $625

∵ The total prize = 1st prize + 2nd prize

∴ The total prize = 1125 + 625

∴ The total prize = 1750

∴ The total prize money for the competition is $1750

Answer:

about 93 weeks

Step-by-step explanation:

divide 1200 by 13 to get your answer which is 92.3076923077 so then you just instead of rounding to 92 you would round to 93 because it would take her more then 92 weeks so the answer would be about 93 weeks

0+2+-4=-2

Step-by-step explanation:

Answer:

each side 5

Step-by-step explanation:

with 2 equal internal base angles, we know this is an isosceles triangle

this being isosceles also tells us that the 2 opposite sides are also equal

Therefore: x + 2 = 3x - 4

solving for x

x - 3x = -4 -2

-2x = -6

x = -6 ÷ -2

× = 3

substituting x:

x +2 = 3 + 2 = 5

3x-4 = 9 - 4 = 5
