Answer:
x = 8, y =
Step-by-step explanation:
Both 8 and x sides are congruent so they're equal.
Add 64 + 64.
Square root 128
Final answers: x = 8, y =
Answer:
12+√74 ≈ 20.60
Step-by-step explanation:
The side lengths of this right triangle are 5 and 7 units, so the length of the hypotenuse is ...
b² = a² +c² = 5² +7² = 74
b = √74
The perimeter is ...
P = a + b + c = 5 + √74 + 7
P = 12+√74 ≈ 20.60
Answer:
8
Step-by-step explanation:
Eric's salary: y=75x+1400
Nancy's salary: y=250x.
Solve the system of equations to get 8.
The velocity or speed of the kayaker going north at a speed of 3 m/s and that of the current going east at a speed of 2 m/s create a resultant speed of √13 m/s. The new distance that has to be traveled by the kayaker in order to move 100 m north is calculated through the equation,
3 / √13 = 100 / x
The value of x is 120 m. The total time it will take for the kayaker to reach the destination is,
t = 120 / √13 = 33.33 s
<u>Answer:</u>
Justine is correct, because the point (0,0) does not line up with the straight line that contains the other points.
<u>Step-by-step explanation:</u>
From points (-3,-8), to (-1,-4) the points make a straight line because the x coordinates increase by 1 while the y coordinates increase by 2. Up until the last y coordinate. While the x coordinate follows its pattern, the y coordinate increases by 4 when it's supposed to increase by 2.
