Answer:
D. One
Step-by-step explanation:
A parallelogram will have two sets of equal sides. Since we have that fact, all we need to know are the angles.
A quadrilateral will have a total of 360° in its angles. If only one angle is equal to 90°, then we can do <u>the math</u> to figure out that all the others must be 90° as well. A rectangle is a parallelogram with the opposite sides being parallel and all the angles being 90°. This then answers the question.
"<u>The Math</u>"
-> Keep in mind there will be four angles
-> Once we subtract the first angle of 90°, we will have three angles left. Hence why we divide by 3.
360° - 90° = 270°
270° / 3 = 90° ✓
Answer:
the equation says that energy and mass (matter) are interchangeable; they are different forms of the same thing.
Step-by-step explanation:
Answer:
S(0, 2)
Step-by-step explanation:
Midpoint Formula: 
Step 1: Plug in known variables
5 = (10 + x)/2
-8 = (18 + y)/2
Step 2: Solve
10 = 10 + x
x = 0
-16 = 18 + y
y = 2
Step 3: Write coordinates
(0, 2)
Answer:
h = 10 bc 4.7 x 10 = 47
f = 36 bc 6 x 36 = 216
g = 3.5 bc 3.5 + 1.6 = 5.1
unlock number equation = f - g x h or 36 - 3.5 x 10
unlock number: 1
