Step-by-step explanation:

365 x 24 = 8,760

365 x 6 = 2,190

8,760 - 2,190 = 6,570

6,570 / 24 = 273 3/4

Jordan spent 22% of his time doing math homework. If hw spent 11 minutes on his math homework. How many minutes did he spend on

Angelina_Jolie [31]

Jordan spends 50 minutes on his homework.

Step-by-step explanation:

Given,

Time spent on Maths homework = 11 minutes

This represents the 22% time of his total homework.

Let,

x be the total time spent on homework.

22% of x = 11

$\frac{22}{100}*x=11\\0.22x=11$

Dividing both sides by 0.22

$\frac{0.22x}{0.22}=\frac{11}{0.22}\\x=50$

Jordan spends 50 minutes on his homework.

For what values of x and y must ABCD be a parallelogram?

n200080 [17]

Step-by-step explanation:

We know that vertically opposite angles of a parallelogram are equal .

$\angle ABC =\angle ADC\ and \ \angle BAD = \angle DAC$

⇒ $3x^{\circ}=(4x-21)^{\circ} \ and \ 3y^{\circ}=(y+78)^{\circ}$

⇒ $3x^{\circ}-4x^{\circ}=-21^{\circ} \ and \ 3y^{\circ}-y^{\circ}=78^{\circ}$

⇒ $-x^{\circ}=-21^{\circ} \ and \ 2y^{\circ}=78^{\circ}$

⇒ $x^{\circ}=21^{\circ} \ and \ y^{\circ}=39^{\circ}$

Find the equation, in point-slope form, of the line that passes -3 and passes through the point (1,2). plz show your work.

Maslowich

Substitute the given values for the parameters in the point-slope form of the equation of a line. That form is
y - k = m(x - h)
for point (h, k) and slope m.

You have (h, k) = (1, 2) and m=-3, so your equation is
y - 2 = -3(x - 1)

A tree is leaning at a 5° angle from vertical, making an 85° angle with the ground. when the sun is at a 65° angle of elevation,

White raven [17]

using the law of sines, the approximate length of the tree is calculated as: C. 45 ft.

<h3>What is the Law of Sines?</h3>

The law of sines is given as: sin A/a = sin B/b = sin C/c, which is used to solve a triangle.

Given the following:

H = the length of the tree = ? (b)
Let sin A = 30°
a = 25
Sin B = 65°

Apply the law of sines

sin 30/25 = sin 65/H

H = (sin 65 × 25)/sin 30

H ≈ 45 ft.
