Find the measure of each
exterior angle of regular polygonof a 9sides.
Answer:
40
Step-by-step explanation:
Any regular polygon has exterior angles = to 360 / number of sides.
so a 9-gon has 9 sides. The exterior angle = 360 / 9 = 40
Each exterior angle will be 40 degrees.
Try it with simpler n-gons. A triangle has 3 sides. The exterior angle is 360 / 3 = 120
A square has 4 sides. Each exterior angle is 360 / 4 = 90
Why, when packing a shopping bag, you will not put the detergent, baked chicken and frozen meats in the same bag?
Answer:
i think people do that so the products don't get destroyed. like, you wouldn't put bread and canned foods in the same bag. or maybe it's to organize them by category, etc. so when you get home to put up the groceries, they're all in the same place. like all the fridge items are in this bag. i don't know honestly. just my opinion.

Select all the quadrilaterals that have diagonals which cross at right angles. Please help..
Answer: C and D
Step-by-step explanation:
We need to find all the figures that are rhombuses. These figures are C and D.
The quadrilaterals C and D are those for which the diagonals cross at right angles.
What is a Quadrilateral?Quadrilateral are closed geometrical shapes having four sides, four angles and four vertices. Some of the common quadrilaterals include rectangles, square, parallelogram and the rhombus.
Interior angles of any type of quadrilateral always sums up to 360°.
Diagonals of a quadrilateral is the straight line formed by joining opposite vertices.
For every quadrilateral, there are two diagonals.
Figure A is a rectangle. The diagonals of a rectangle bisects each other, but is not perpendicular bisector. This means that diagonals of figure A does not cross at right angles.
Figure B is a parallelogram. Properties of diagonals are almost same in rectangles and quadrilateral. Diagonals bisect each other, but is not perpendicular. So diagonals of figure B also does not cross at right angles.
Figure C is rhombus. Diagonals of a rhombus perpendicularly bisect each other. Therefore diagonals of figure C cross at right angles.
Figure D is square. Again the diagonals of a square perpendicularly bisect each other. Therefore diagonals of figure D cross at right angles.
Hence diagonals of figures C and D cross at right angles.

A barrel with a 60 liter capacity is half full. We can transfer all that liquid into 240 bottles with a quarter liter of capacity.
True False
[tex]\frac{1}{4}[/tex]Answer:
False
Step-by-step explanation:
A barrel with a 60 liter capacity is half full, therefore there are 30 liters in the barrel.
If we use 240 bottles with a capacity of 1/4 liters, how many liters do we need to fill the 240 bottles?
240 x [tex]\frac{1}{4}[/tex]L = [tex]\frac{240}{4}[/tex] = 60L
Therefore, it is false because we only have 30 liters, we can't fill the 240 bottles

Step-by-step explanation:
Rewrite the equation in vertex form.
Complete the square for
[tex]2 {x}^{2} + 2x - 4[/tex]
Use the form
[tex]a {x}^{2} + bx + c[/tex]
to find the values of a, b, and c.
a = 2
b = 2
c = −4
Consider the vertex form of a parabola.
[tex]a(x + d) ^{2} + e[/tex]
Find the value of d using the formula
[tex]d = \frac{b}{2a} [/tex]
[tex]d = \frac{1}{2} [/tex]
Find the value of e using the formula
[tex]e = c - \frac{ {b}^{2} }{4a} [/tex]
[tex]e = - \frac{9}{2} [/tex]
Substitute the values of a, d, and e into the vertex form
[tex]2(x + \frac{1}{2} ) ^{2} - \frac{9}{2} [/tex]
Set y equal to the new right side.
[tex]y = {2(x + \frac{1}{2}) }^{2} - \frac{9}{2} [/tex]
Use the vertex form,
[tex]y = a(x - h) ^{2} + k[/tex]
to determine the values of a, h, and k.
a = 2
h = -1/2
k = -9/2
Find the vertex (h,k).

Evaluate the composite function, where g(x) = x^2 – 7x and h(x) = 7 - 4x^2.
(hºg)(0)
Answer:
7
Step-by-step explanation:
Find (h°g)(0) can also be expressed as h(g(0)). Begin by calculating g(0). To evaluate the function g at 0, replace each x with 0. g(0) = (0)²-7(0). (0)²-7(0) is equal to 0 so now 0 becomes the input for h. Evaluate h(0) by replacing each x with 0 in the h function. h(0) = 7 - 4 (0)² = 7 - 0 = 7.

peanuts, p (cups), in this recipe.
a. Write the equation for the relationship that has constant of proportionality
greater than 1. Graph the relationship.
b. Write the equation for the relationship that has constant of proportionality less than 1. Graph the relationship.
Answer:
r = 2/3p
A trail mix recipe asks for 4 cups of raisins for every 6 cups of peanuts.
There is proportional relationship between the amount of raisins, r (cups), and the amount of peanuts, p (cups), in this recipe.
The ratio of raisins and peanuts = 4:6 or 2:3
It would be same for every mixture.
If r cups of raisins and p cups of peanuts then their mixture ratio is r:p
Step-by-step explanation:
pls heart and give brainliest
The equation where the constant of proportionality is greater than 1 is [tex]\mathbf{p = 1.5r}[/tex], and the equation where the constant of proportionality is less than 1 is [tex]\mathbf{r = 0.67p}[/tex]
(a) Constant of proportionality greater than 1
Represent peanuts with p, and raisins with r.
So, the ratio is given as:
[tex]\mathbf{p : r = 6 : 4}[/tex]
Express as fraction
[tex]\mathbf{\frac pr = \frac 64}[/tex]
Multiply both sides by r
[tex]\mathbf{p = \frac 64r}[/tex]
[tex]\mathbf{p = 1.5r}[/tex]
(b) Constant of proportionality less than 1
In (a), we have:
[tex]\mathbf{p = 1.5r}[/tex]
Divide both sides by 1.5
[tex]\mathbf{r = \frac{1}{1.5}p}[/tex]
[tex]\mathbf{r = 0.67p}[/tex]
The graphs of [tex]\mathbf{p = 1.5r}[/tex] and [tex]\mathbf{r = 0.67p}[/tex] are the same.

The best example of nonresponse bias from the scenario of this airline surveying customers is that Satisfied customers might be less likely to complete the survey than dissatisfied customers.
What is nonresponse bias?Nonresponse bias refers to a situation that arises where people are less inclined to provide feedback because their experience was different from those who did.
Satisfied customers would be less inclined to talk about their overall satisfaction than unsatisfied customers as the latter would use the opportunity to make their dissatisfaction known.
