Answer:
The necklace will be 4,000 cm long
Step-by-step explanation:
Here we want to calculate the length of the necklace
Mathematically, that would just be the product of the beads and the diameter of each bead
Hence, we have
10,000 * 0.4 = 4,000 cm
Answer:
a. y = -x
b. Area = xy
c. x = -y
Step-by-step explanation:
a. The perimeter of the garden is the distance all the way around, in this would be x+y+x+y, or 2x + 2y. To solve for y, we’re trying to isolate it on one side. We need to subtract 2x to get 2y = -2x. Divide by 2 to get y = -x.
b. Area is length times width, so x • y, or xy.
c. To express in terms of x, we can take the equation y = -x and multiply it by -1 to get x = -y
Answer:
8 hours estimated.
Step-by-step explanation:
Let's use the formula d=r*t
distance= rate * time
236= 29t
Divide 236 by 29
8 hours estimate as you asked for.
