Answer:

see explanation

Step-by-step explanation:

the translation (x, y) → (x - 4, y + 7)

means subtract 4 from the x-coordinate and add 7 to the y-coordinate of the original coordinate points

R(0, - 4 ) → R'(0 - 4, - 4 + 7 ) → R'(- 4, 3 )

S(- 2, - 1 ) → S'(- 2 - 4, - 1 + 7 ) → S'(- 6, 6 )

T(- 6, 1 ) → T'(- 6 - 4, 1 + 7 ) → T'(- 10, 8 )

Answer:

1) 45 degrees

2) 75 degrees

3) 37 degrees

4) 43 degrees

5) 137 degrees

Step-by-step explanation:

1) Angle 1 is equal to the 45 degree angle above it, so we know it is 45 degrees

2) All triangles are 180 degrees. Angle 2 = 180 - 60 - Angle 1 = 180 - 60 - 45 = 75

3) These three angles = 180 degrees. 180 - 68 - Angle 2 = 180 - 68 - 75 = 37

4) All triangles are 180 degrees. 180 - 100 - Angle 3 = 180 - 100 - 37 = 43

5) 180 - Angle 4 = 180 - 43 = 137

The coffee counter charges ?"$11.00" per pound for kenyan french roast coffee and ?"$13.00" per pound for sumatra coffee. How mu

zloy xaker [14]

Answer: The answer is 13 ponds of each type should be used.

Step-by-step explanation: Given that the coffee counter charges $11.00 per pound for kenyan french roast coffee and $13.00 per pound for sumatra coffee. We are to find the quantity of each type that should be used to make a 26 pound blend that sells for $12.00 per pound.

Let 'x' pound and 'y' pound of kenyan french roast coffee and sumatra coffee be used in the mixture of 26 pound.

So, we have

$x+y=26,~~~~~~~~~~~~~~~~~~~~~~(A)\\\\11x+13y=12\times 26.~~~~~~~~~~(B)$

Multiplying equation (A) by 11 and subtracting from equation (B), we have

$13y-11y=12\times26-11\times26\\\\\Rightarrow 2y=26\\\\\Rightarrow y=13,$

and from equation (A),

$x=26-13=13.$

Thus, 13 pounds of each type of coffee should be used.

Leap years are years in which February has 29 days instead of 28. The device of leap year was invented to keep the calendar in s

goldenfox [79]

Answer:

As you know, a year has around 365 + 1/4 days.

This means that in two years, we have:

365 + 356 + 1/4 + 1/4 = 730 + 1/2

and so on.

adding this up, when we have 4 years we have a full day extra, this is:

1460 + 1

When we divide 1461 by 4, we have 365 with a surpass of 1.

The rule used to keep the calendar in sync with this extra day is adding an extra day to each fourth year.

So each fourth year, we have an extra day in Februray (the Februray 29th), this is called a bisiest year.

The "math rule" used to know if a year is leap or not is:

if a year is not divisible by 4, then it is a common year

else if the year is not divisible by 100 then it is a leap year,

else if the year is not divisible by 400, then it is a common year

if not, the year is a leap year.

Where "year" represents the number of the year.
