Answer:
The combined weight of red and green grapes in total= 7.625 pounds.
Step-by-step explanation:
The amount of red grapes purchased = 3.5 pounds
The amount of green grapes purchased = 4 pounds and 2 ounces
Now, 1 ounce = 0.0625 pounds
So, 2 ounces = 2 x 0.0625 p = 0.125 pound
So, the amount of green grapes purchased = 4 pounds + 0.125 pounds
= 4. 125 pounds
Now, the combined weight of grapes = weight of ( red + green) grapes
= 3.5 pounds + 4. 125 pounds
=7.625 pounds
Hence, the combined weight of the red and green grapes she bought in total is 7.625 pounds.
Hello from MrBillDoesMath!
Answer: (sin(@)) ^2 + (cos(@)) ^2 = 1 for all angles @.

Take a point, say in the first quadrant. on a unit circle (circle with radius 1) Let that point by (x,y). The from the Pythagorean theorem.
x^2 + y^2 = r^2 or as r = 1
x^2 + y ^2 = 1 ("Equation 1")
If you drop a line from (x,y) perpendicular to the x axis you find that
y = r [email protected] or y = [email protected] as r =1.
and
x = r [email protected] or x = [email protected] as r = 1
(Look at the triangle formed by the radius, the perpendicular line and the positive x axis). Substitute these x and y values in Equation 1 above. This gives
([email protected])^2 + ([email protected])^2 =1
which is true for all angles. This is a key "pattern" or identity that you should commit to long term memory!

25.4 mm = 1 inch
1 mm = (1/25.4)
56 mm = 56 *(1/25.4)
≈ 2.205 inches.
