RSTV is a quadrilateral

Interior angles of a quadrilateral sum to 180

Sum of given angles:

2n + 6n + 2n + 5n = 180°
15n = 180°
n = 12°

The angles are:

2*12°= 24°, 6*12° = 72°, 2*12° = 24°, 5*12° = 60°

(3)

Sum of angles of a regular 18-gon:

S = 180°(18 - 2) = 2880°

Each interior angle is:

2880°/18 = 160°

(4)

Sum of interior angles of a convex heptagon (7-sided polygon):

S = 180°(7 - 2) = 900°

(5)

Sum of exterior angles of any polygon is 360°

Each exterior angle of a regular nonagon (9-sided polygon) is:

360°/9 = 40°

Lynne feeds her cat 65 g of cat food per day. About how many ounces of cat food will she feed her cat in 5 weeks? 1 oz≈28.3 g

Svet_ta [14]

Consumption in Grams would be 65 x 7 x 5 which 2,275 If we use the conversion rate of 28.3 grams to an ounce then the number of ounces will be found by completing this sum 2275 divided by 28.3 which is 80 Ounces when rounded down

Help quickly please!!!

sineoko [7]

Answer:

M= -2

B=1

Step-by-step explanation:

Y-intercept is the point where the line crosses through the y line, so you can clearly see that that point is (0,1) we only write the y value because for a y intercept the x value will always be zero

Slope is the rise over run, meaning how much the y value changes over how much the x value changes, so for the two points we use our formula:

$\frac{y1-y2}{x1-x2}$

So now input how much it changes by adding the numbers from each coordinate:

$\frac{(-3)-(1)}{(2)-(0)}$

Simplify:

$\frac{-4}{2}$

But we write it as:

-4/2

This is because this looks more like division

Divide:

-4/2=-2

So, your slope is -2 and the y- intercept is 1

I hope this helps u pls give a brainliest and a thx ;)

Leena loves peanut butter. today, she ate four tablespoons of it. if there are 6 mg of vitamin e in four tablespoons of peanut b

velikii [3]

First, we need to know that the current recommended daily allowance of Vitamin E is 15 milligrams. If Leena ate four tablespoons of peanut butter, thus receiving only 6 milligrams, then we can determine the percentage by first dividing 100 into 15 parts (which gives us 6.66), and then multiply that answer by 6 (6 x 6.66), which gives us precisely 40. Thus, the answer is 40 percent.

Neptune’s average distance from the sun is 4.503 x 10e9 km. Mercury’s average distance from the sun is 5.791 x10e9 km.about how

Igoryamba

Answer:

77.76 times

Step-by-step explanation:

The average distance of Neptune from the sun

= 4.503 × 10 ⁹ k m .

and Mercury = 5.791 × 10 ⁷ k m .

Hence neptune is ( 4.503 × 10 ⁹) ÷ (5.791 × 10 ⁷ ) times farther from the sun than mercury

i.e.( $\frac{4.503}{5.791}$ ) × 10⁹⁻⁷ times

= 0.7776 × 10 ² times

= 77.76 times.
