Since it is a 45-45-90 right triangle, the formula is:
Hypotenuse= sqrt2 * leg
Since you know hypotenuse = 9sqrt2 the leg has to be 9
Answer:
13/4 - (13,4) - however your teacher wants you to write it out.
Step-by-step explanation:
Rise (y) over Run (x)
Equation:
y2 - y1
over
x2 - x1
Inputting the numbers, 6 - -7 (aka 6+7) over -3 - -7 (aka -3+7)
6+7 = 13
-3+7 = 4
13/4 - The line is rising moving towards the right.

Answer: 1 3/8 or 1 whole and 3/8
Step-by-step explanation: first you do 77/72 multiplied by 9/7 and you get
1 and 189/594 then you simplify and get 1 and 63/168 and you simplify again and you get 1 and 21/56 then you simplify again and get 1 and 3/8
MEANINGS
-SIMPLIFY~WHEN YOU SIMPLIFY YOU DIVIDE THE FRACTION BY A NUMBER DIVISIBLE BY BOTH THE NUMERATOR AND DENOMINATOR
EXAMPLES~ 2/4 YOU SIMPLIFY IT BY DIVIDING BOTH THE NUMERATOR AND DENOMINATOR BOTH BY 2 AND YOU GET 1/2

Answer:
Logan - 7 hours
Sarah - 6 hours
Step-by-step explanation:
Given Logan can iron 40 shirts per hour, and Sarah can iron 35 shirts per hour.
Also given that they worked together a combined hours of 13 hours
Let the number of hours worked by Logan is x and the number of hours worked by Sarah be y hours
Given x + y = 13
Also given that they together ironed 490 shirt's
which means 40x + 35y = 490
solve the above two equations by elimination
Multiply the first equation with 35 and subtract from the second equation we get
40x - 35x = 490 - 455
5x = 35
x = 7 hours
Substitute this value in the first equation to get the values of y
x + y = 13
y = 13 - x
y = 13 - 7 = 6 hours
therefore the number of hours worked by Logan is 7 hours and the number of hours Sarah worked is 6 hours
