Ok, use the sum of triangle theorm all angles of the triangle has a sum of 180 degrees. B is 90 degrees because it labeled it self ABC the A angle seems by the degree to be at the top of the triangle and there needs to be a 90 degree angle in a right triangle. Now if you add 90 + 28 you get 118 degrees subtract that from the sum of all the angles ( 180 degrees), and get 62 degrees as angle C. Angle A is 28 degrees, angle B is 90 degrees, angle C is 62 degrees.

The point slope form of the equation of the line that passes through (-5-1) and (10.-7) is

Natalka [10]

Answer:

The standard form of the equation for this line can be:

l: 2x + 5y = -15.

Step-by-step explanation:

Start by finding the slope of this line.

For a line that goes through the two points $(x_0, y_0)$ and $(x_1, y_1)$ ,

$\displaystyle \text{Slope} = \frac{y_{1} - y_{0}}{x_{1} - x_{0}}$ .

For this line,

$\displaystyle \text{Slope} = \frac{(-1) - (-7)}{(-5) - 10} = -\frac{2}{5}$ .

Find the slope-point form of this line's equation using

$\displaystyle \text{Slope} = -\frac{2}{5}$ , and
The point $(-5, -1)$ (using the point $(10, -7)$ should also work.)

The slope-point form of the equation of a line

with slope $m$ and
point $(x_{0}, y_{0})$

should be $l:\; y - y_{0} = m(x - x_0)$ .

For this line,

$\displaystyle m = -\frac{2}{5}$ , and
$x_0 = -5$ , and
$y_0 = -1$ .

The equation in slope-point form will be

$\displaystyle l:\; y - (-1) = -\frac{2}{5}(x - (-5))$ .

The standard form of the equation of a line in a cartesian plane is

$l: \; ax + by = c$

where

$a$ , $b$ , and $c$ are integers. $a \ge 0$ .

Multiply both sides of the slope-point form equation of this line by $5$ :

$l:\; 5 y + 5 = -2x -10$ .

Add $(2x-5)$ to both sides of the equation:

$l: \; 2x + 5y = -15$ .

Therefore, the equation of this line in standard form is $l: \; 2x + 5y = -15$ .

Stephen and Laura want to split a bag of fun-sized candy, and decide to use the divider-chooser method. The bag contains 100 Sni

Lubov Fominskaja [6]

Answer:

a) $4.14

b) No

c) 28 Snickers, 40 Milky Ways, 63 Reese's

72 Snickers, 60 Milky Ways, 37 Reese's

Step-by-step explanation:

Since 1 Snickers is $0.01, 1 Milky Ways is $0.03, and 1 Reese's is $0.04:

30 Snickers: 30(0.01) = 0.3

40 Milky Ways: 40(0.03) = 1.2

66 Reese's: 66(0.04) = 2.64

The value is: 0.3 + 1.2 + 2.64 = 4.14

The total value is: 1 + 3 + 4 = 8

A fair share must have the same value, 8/2 = 4. Since one half is 4.14 which is more than 4, it is not a fair share.

First half:

28 Snickers: 28(0.01) = 0.28

40 Milky Ways: 40(0.03) = 1.2

63 Reese's: 63(0.04) = 2.52

Second half:

72 Snickers: 72(0.01) = 0.72

60 Milky Ways: 60(0.03) = 1.8

37 Reese's: 37(0.04) = 1.48

How do i do KCF ? for 6th grade ;~;

Virty [35]

KCF

Keep

Change

Flip

lets say we are dividing 1/2 and 1/4. you would keep 1/2 the same, change the division sign to a multipluction, and flip 1/4 so that it becomes 4/1. you would then just multiply 1/2 and 4/1
