Answer: 5 pieces
===================================================
Explanation:
Note how
(number of pieces)*(length per piece) = 5*(3/5) = 15/5 = 3
which is the total length of the original rope.
So that's why the answer is 5.
We can get this answer through either guess and check, or we can divide 3 over 3/5 like so
3 divide 3/5 = (3/1) divide by (3/5) = (3/1)*(5/3) = 15/3 = 5
The second fraction 3/5 flips when we divide by it. Also the division changes to a multiplication when we flip the second fraction.
Find the equation of the line that is parallel to the given line and passes through the given point. y=0,5x-2;(-2,1)
The equation is y=
Answer:
y = 0.5x
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 0.5x - 2 ← is in slope- intercept form
with slope m = 0.5
Parallel lines have equal slopes, thus
y = 0.5x + c ← is the partial equation
To find c substitute (- 2, 1) into the partial equation
- 1 = - 1 + c ⇒ - 1 + 1 = 0
y = 0.5x + 0 , that is
y = 0.5x ← equation of parallel line

A plane traveled 880 miles each way to Bangkok and back. The trip there was with the wind. It took 10 hours. The trip back was into the wind. The trip back took 20 hours. Find the speed of the plane in still air, in miles per hour.
Step-by-step explanation:
Let x miles/hr be the speed of the plane in still air and y miles/hr be the speed of the wind.
We have 10hr * (x + y)miles/hr = 880 miles
and 20 hr * (x - y)miles/hr = 880 miles.
=> (x + y) = 88 and (x - y) = 44.
Therefore 2x = 88 + 44 = 132 and x = 66.
The speed of the plane in still air is 66 miles per hour.

Evaluate the expression 43 + [(96 ÷ 8) × 5] – 42.
Answer:
Your answer is 61.
Step-by-step explanation:
43+[(96÷8) × 5]-42, first you have to divide 96 and 8.
96 divided by 8 is 12. next you multiply 12 and 5. 12 multiplied by 5 equals 60. then you take 60 and add the 43. you will get 103, then you take 103 and subtract 42, and you will get 61.
Example:
43 + [(96 ÷ 8) × 5] - 42
43 + [12 × 5] - 42
43 + 60 - 42
103 - 42
( 61 )
lessils used 25% of half a gallon (64 ounces) of milk for a recipe how many ounces of milk where left
Answer:
There were 48 ounces of milk left
Step-by-step explanation:
∵ Lessils used 25% of half a gallon of milk
→ Assume that the total amount of the milk is 25%
∴ The amount of milk left = 100% - 25% = 75%
∵ Half gallon = 64 ounces
→ That means the amount of milk left is 75% of 64 ounces
∴ The amount of milk left = 75% × 64
→ Divide 75% by 100 to change it to decimal
∵ 75% = 75 ÷ 100 = 0.75
∴ The amount of milk left = 0.75 × 64
∴ The amount of milk left = 48 ounces
∴ There were 48 ounces of milk left

what is -4 = k - (-6) ?
Answer: k = -10
Step-by-step explanation:
-4 = k + 6
-4 - 6 = k
-10 = k
Answer:
k = -10
Step-by-step explanation:
To solve for k, isolate it. -(-6) is the same as + 6. So the equation can now be written as -4 = k + 6. Subtract 6 from both side to get -10 = k.
