Sean's party will cost $60 if he invites 12 guests. Which expression does NOT equal the amount that Sean will spend per party guest in dollars?

Answers

Options :

A) 12⟌60

B) 60 ÷ 12

C) 60⟌12

Answer:

C) 60⟌12

Step-by-step explanation:

Given that :

Total cost of inviting 12 guests to a party = $60

To obtain the cost per guest :

Total cost of invitation / number of guests

That is ; we divide the cost of inviting the guests by the number of guests invited

$60 / 12 = 12⟌60

The expression 60⟌12 is incorrect as this means 12 / $60

A plane traveling with a velocity measured in meters per second, is described by vector a = 5,6). Find the
speed of the plane.

Answers

Answer:

The speed of the plane is [tex]v=1.2\: m/s[/tex]

Step-by-step explanation:

The vector (5,6) represents a point in the coordinate system time-position.

So, we have that at t = 5 s the position is x = 6.

Let's recall that the slope of this vector is the speed, then using the tangent definition:

[tex]v=\frac{x}{t}=\frac{6}{5}[/tex]

[tex]v=1.2\: m/s[/tex]

PLEASE SOMEONE!!HELP!! I need the answer right now

Answers

Answer:

m = -1, b = 5.

Step-by-step explanation:

We can find the slope, m, by plugging in our coordinates into the slope formula: [tex]\frac{y2-y1}{x2-x1} =\frac{2-7}{3-(-2)}=\frac{-5}{5}=-\frac{5}{5}=-\frac{1}{1}=-1[/tex]. That gives us the slope. Now we can fill that in the slope intercept formula: [tex]y=-1x+b[/tex]. We know one of the coordinates and the slope, which allows to find the y-intercept. We know that for every 1 unit down on the line, we move 1 unit right, and vice versa. Meaning we can just count down (or up in this case), so, (-2, 7), (-1, 6), (0, 5). Therefore, our y intercept is 5.

The curved surface area of a cylinder of height 28cm is 352sq.cm. Find the diameter of the base of the cylinder​

Answers

Answer:

d = 4cm

Step-by-step explanation:

curved surface area (CSA) of cylinder = [tex]2\pi rh[/tex]

h = 28cm and CSA = 352[tex]cm^{2}[/tex]

[tex]2\pi rh[/tex] = 352

2 * [tex]\frac{22}{7}[/tex] * r * 28 = 352

[tex]r = \frac{352*7}{2*22*28}[/tex]

after calculating, you will get r = 2cm

so diameter = 4cm

5. A robot that picks up tennis balls is on a straight path from (8,6) toward a ball at (-10,-5). The robot picks up a ball at (-10,-5) and then turns 90° right. What are the coordinates of appoint that the robot can move toward to pick up the last ball?​

Answers

Answer:

Step-by-step explanation:

so this question is about perpendicular lines.    keep in mind that a perpendicular line has a reciprocal slope of opposite sign, from the line it's perpendicular to .  :)  okay so what is that line the robot is on, let's first  

find the slope  , m

m = (y2 - y1)  / ( x2 - x1)  

P1 = (8,6)  in the form ( x1,y1)

P2= (-10,-5) in the form (x2,y2)

then

m = (-5-6) / (-10-8)

m = -11 / -18

m = 11/ 18

and then lets use the point-slope formula with the slope we just found and one of the given points, let's pick  P1

y-6 = 11/18(x-8)

y = 11/18x - 88/18 + 6

y = 11/18x -88/18 + 108/18

y = 11/18x + 20/18

now let's take the reciprocal of the slope and change the sign,  then we have

y = - 18/11x +20/18  ( coordinates robot can move on )

on the graph I'm attaching the green line is the one where the robot first moves, then the purple one.. is the one it turns 90 ° on to .

AABC is dilated by a factor of 4 to produce AA'B'C'.

What is A'C, the length of AC after the dilation? What is the measure of ZA?

Answers

Answer:

A

Step-by-step explanation:

because the sky is blue

The length of AC after dilation will be 20. Then the measure of the angle ∠A' will be 37°.

We have given that,

AABC is dilated by a factor of 4 to produce AA'B'C'.

What is dilation?

Dilation is the process of increasing the size of an item without affecting its form. Depending on the scale factor, the object's size can be raised or lowered.

The triangle ΔABC is dilated by a factor of 4 to produce the triangle ΔA'B'C'.

Then the length of AC after dilation. We have

A'C' = scale factor x AC

A'C' = 4 x 5

A'C' = 20

Then the measure of the angle ∠A' will be

There is no effect of dilation on the angle.

∠A = ∠A' = 37°

Thus, the correct option is A.

Your task is to group the arrays a[i] by their mean values, so that arrays with equal mean values are in the same group, and arrays with different mean values are in different groups. Each group should contain a set of indices (i, j, etc), such that the corresponding arrays (a[i], a[j], etc) all have the same mean. Return the set of groups as an array of arrays, where the indices within each group are sorted in ascending order, and the groups are sorted in ascending order of their minimum element.ExampleFora = [[3, 3, 4, 2], [4, 4], [4, 0, 3, 3], [2, 3], [3, 3, 3]]the output should bemeanGroups(a) = [[0, 4], [1], [2, 3]]mean(a[0]) = (3 + 3 + 4 + 2) / 4 = 3;mean(a[1]) = (4 + 4) / 2 = 4;mean(a[2]) = (4 + 0 + 3 + 3) / 4 = 2.5;mean(a[3]) = (2 + 3) / 2 = 2.5;mean(a[4]) = (3 + 3 + 3) / 3 = 3.There are three groups of means: those with mean 2.5, 3, and 4. And they form the following groups:Arrays with indices 0and 4 form a group with mean 3;Array with index 1 forms a group with mean 4;Arrays with indices 2and 3 form a group with mean 2.5.Note that neithermeanGroups(a) = [[0, 4], [2, 3], [1]]normeanGroups(a) = [[0, 4], [1], [3, 2]]will be considered as a correct answer:In the first case, the minimal element in the array at index 2 is 1, and it is less then the minimal element in the array at index 1, which is 2.In the second case, the array at index 2 is not sorted in ascending order.Fora = [[-5, 2, 3], [0, 0], [0], [-100, 100]]the output should bemeanGroups(a) = [[0, 1, 2, 3]]The mean values of all of the arrays are 0, so all of them are in the same group.Input/Output I WILL GIVE BRAINLIEST!!!
