HELP! What’s the average of 279 minutes?

Mathematics

Rudik [331]3 years ago

<h3>Answer: 56 minutes</h3>

1 hour = 60 minutes

The time values given, in minutes, are:

25, 55, 60, 94, and 46

going from monday to friday in that exact order

Add up the values, then divide by 5. This is because there are 5 values

So adding up the values gets us: 25+55+60+94+46 = 280

Then dividing by 5 leads to this answer: 280/5 = 56

note: you must convert the "1 hour" to "60 minutes" because each time value must be in the same units. Otherwise, its like mixing apples and oranges which makes no sense.

Please help! i'm confused!<br> Find the area of a kites with diagonals 9in and 12in.
kolbaska11 [484]
Notice the picture
the rhombus, or kite, is really just 4 triangles
all sides are the same lenght in a rhombus,

thus, find the area of all of the triangles,
and you already have two sides given,
and then, add them up

or just find the length of one, and multiply times 4 :)

recall, area of a triangle = 1/2 bh

Which point lies on the line with the point slope equation y-2=5 x-6
egoroff_w [7]
(y-y1) = m(x-x1)
y-2 = 5(x-6)

Therefore, point (x1,y1) lies on the line of equation
Therefore, point (6,2) lies on the line with the point slope equation y-2=5(x-6)

Consider the point P = (4,-1) and the line L, given by the equation y=2x+3.
3241004551 [841]

Answer:

A. y=2x-9

B. y=-\frac{1}{2}x+1

Step-by-step explanation:

A. Parallel lines have the same slope. That means the line y=2x+3 has the same slope as any line parallel to it. So the slope is 2.

Using m=2, substitute it and (4,-1) into the point slope form and simplify to find the y-intercept.

y-y_1 = m(x-x_1)\\y--1=2(x-4)\\y+1=2(x-4)\\y+1=2x-8\\y=2x-9

B. Perpendicular lines have slopes which are negative reciprocals of each other. The slope of the line y=2x+3 is 2. The slope perpendicular to it is -1/2.

Using m=-1/2, substitute it and (4,-1) into the point slope form and simplify to find the y-intercept.

y-y_1 = m(x-x_1)\\y--1=-\frac{1}{2}(x-4)\\y+1=-\frac{1}{2}(x-4)\\y+1=-\frac{1}{2}x+2\\y=-\frac{1}{2}x+1

I need help ASAP I only have 30 more mins!!
atroni [7]

Answer:

x = 2

Step-by-step explanation:

if the line passes through the x axis it means  we should use the of x

if it passes through y we should use value of y

in this question perpendicular means at a 90 degree angle

the coordinates is 2,6

so x must be 2
