Answer:

25 Feet

Step-by-step explanation:

Im sorry if i am wrong, but it is 25 because the girl is 5 feet, and one feet less of a shadow. So it is obvious to me that the tree is 1 foot larger.

Answer:

Note:  The expression "h =300- pi r /pi r" would equate to 299, as written.  I find h = (300 - π[tex]r^{2}[/tex] )/πr to be the equation for height.

Step-by-step explanation:

The total surface area of a sylinder is 2πr(h+r) where h is the height and r is the radius.  That consists of top and bottom disks, each with an area of π[tex]r^{2}[/tex], for a total of 2π[tex]r^{2}[/tex].  The side is a  continous sheet that has an area of 2πrh, where h is the height.  2πr is the circumference of the can, so the surface area of the side is 2πrh.

The total surace area of a closed cylinder is therefore 2π[tex]r^{2}[/tex] + 2πrh.

2π[tex]r^{2}[/tex] + 2πrh = 600

π[tex]r^{2}[/tex] + πrh = 300

πrh = 300 - π[tex]r^{2}[/tex]

h = (300 - π[tex]r^{2}[/tex] )/πr

Answer:cim not sure tho

Step-by-step explanation:

Answer:

Y > 2x - 3

Y > -1/2x + 2

Step-by-step explanation:

The dotted line is a function of y=2x - 3,

And the solid line has a function of y= -1/2x + 2

Because the line is dotted for the first line I picked, it is > and because the other is solid it is >.

Answer:

If you've written it correctly, the answer is 2.25.

Step-by-step explanation:

Can be written as:

0.5 * (2.5 * 4.8 - 7.5).

Perform the multiplications inside the brackets, first:

0.5 * ( 12 - 7.5)

Then perform the remaining arithmetic inside the brackets:

0.5 * ( 4.5)

Perform the last arithmetic:

2.25.

Again, that's if you've written it correctly, and when you say 4 4/5-7 1/2 this actually means four and four fifths (4.8) minus seven and a half (7.5).

We have to find out the value of the fraction.

Let us assume that:

[tex] \sf \longmapsto x =2 + \dfrac{1}{2 + \dfrac{1}{2 + \dfrac{1}{2 + ... \infty} } } [/tex]

We can also write it as:

[tex] \sf \longmapsto x =2 + \dfrac{1}{x} [/tex]

[tex] \sf \longmapsto x =\dfrac{2x + 1}{x} [/tex]

[tex] \sf \longmapsto {x}^{2} =2x + 1[/tex]

[tex] \sf \longmapsto {x}^{2} - 2x - 1 = 0[/tex]

Comparing the given equation with ax² + bx + c = 0, we get:

[tex] \sf \longmapsto\begin{cases} \sf a =1 \\ \sf b = - 2 \\ \sf c = - 1 \end{cases}[/tex]

By quadratic formula:

[tex] \sf \longmapsto x = \dfrac{ - b \pm \sqrt{ {b}^{2} - 4ac } }{2a} [/tex]

[tex] \sf \longmapsto x = \dfrac{2 \pm \sqrt{ {( - 2)}^{2} - 4(1)( - 1)} }{2 \times 1} [/tex]

[tex] \sf \longmapsto x = \dfrac{2 \pm \sqrt{4 + 4} }{2 \times 1} [/tex]

[tex] \sf \longmapsto x = \dfrac{2 \pm \sqrt{8} }{2} [/tex]

[tex] \sf \longmapsto x = \dfrac{2 \pm2 \sqrt{2} }{2} [/tex]

[tex] \sf \longmapsto x = 1 \pm\sqrt{2}[/tex]

[tex] \sf \longmapsto x = \begin{cases} \sf 1 + \sqrt{2} \\ \sf 1 - \sqrt{2} \end{cases}[/tex]

But "x" cannot be negative. Therefore:

[tex] \sf :\implies x = 1 + \sqrt{2}[/tex]

So, the value of the fraction is 1 + √2.

Answer:4/6

Step-by-step explanation:

The measure of angle ∠B will be 66 degrees.

The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180 °.

D is on side AB of triangle ABC. We know triangle ABC is similar to triangle ACD and angle A = 48 degrees. If BC = CD.

∠ABC = ∠ACB = x (Isosceles triangle property)

In △ABC, the angle sum is 180°. Then we have

∠ABC + ∠ACB + ∠ABC = 180°

x + x + 48° = 180°

2x = 132°

x = 66°

Then

∠BCA = ∠BCD + ∠DCB = 66°

∠BCD = 66° − 18°

∠BCD = 48°

Now, In ΔBCD, then we have

∠BCD + ∠BDC + ∠DBC = 180°

48° + ∠BDC + 66° = 180°

∠BDC = 66°

We know that ∠BDC = ∠DBC,

∠DBC = ∠BDC

∠DBC = 66°

The measure of angle ∠B will be 66 degrees.

The number 18 in the form of complex numbers will be written as 18 + 0i.

Every complex number may be represented in the form a + bi, where a and b are real numbers. A complex number is an element of a number system that extends the real numbers with a specific element labeled I sometimes known as the imaginary unit, and satisfies the equation i² = 1.

The given number is 18. The number in the form of a complex number can be written as:-

Complex number =  a + bi

Complex number =  18 + 0i

Therefore, the number 18 in the form of complex numbers will be written as 18 + 0i.

40° and 50°

Answer:

50° and 40°

Step-by-step explanation:

Complementary angles sum to 90°

let one angle be x then the other is x - 10

x + x - 10 = 90

2x - 10 = 90 ( add 10 to both sides )

2x = 100 ( divide both sides by 2 )

x = 50

x - 10 = 50 - 10 = 40

The angle measures are 50° and 40°
