Answer:

You can make NO triangles.

When given 3 sides of a triangle, The longest side must be LESS than the sum of the other 2 sides.

Longest Side = 50 cm

50 is NOT less than 14 + 10, therefore, we have no triangle.

1 a.) 20cm^2 to mm^2

mixas84 [53]

Answer:

a) 200 mm^2

b) 500 mm^2

c) 3.75e + 8

d) 6390 cm^2

e) 650 cm^2

f) 20 m/s

Step-by-step explanation:

For a) and b): 1 cm = 10 mm, multiply 20 (and 50) by 10

For c): the formula is to multiply 1e + 8

For d): 1 Liter = 1000 Cubic Centimeters (hopefully that's what you're referring to)

For e): 10 mm = 1 cm, divide by 10

For f): divide the value by 3.6

What is the value ofcos pie value

Hitman42 [59]

Cos(pi) = -1

You should have this memorized along with other values such as
sin(0) = 0
cos(0) = 1
sin(pi/2) = 1
cos(pi/2) = 0
sin(pi) = 0
cos(pi) = -1
sin(3pi/2) = -1
cos(3pi/2) = 0

and remember that tan = sin/cos

A set of N = 20 exam scores has a mean of m = 50. The instructor discovered that an error was made grading one exam, so 20 point

tatuchka [14]

Answer:

The new mean for the exam scores is 51

Step-by-step explanation:

the mean can be calculated using the formula

mean of scores = $\frac{Sum total of scores}{Number of students}$

before the 20 points was added, the mean of the score was = 50.

Inserting this into the formula, we have:

50 = $\frac{Sum total}{20 students}$

from this, we can compute the sum total of the scores as

sum total = 50 × 20 = 1000

when the extra 20 marks is added, the sum of the entire scores will be changed to 1000 + 20 = 1020.

Hence the new mean will be computed as (New Sum total of scores / Number of students)

= $\frac{1020}{20}$ = 51.

∴ The new mean of the scores is = 51
