Answer:
The percent error of the measurement, to the nearest tenth of a percent is
Step-by-step explanation:
Estimated length of a line = 12.4 inches
Actual length of the line = 15.7 inches
Error = 15.7 - 12.4 = 3.3 inches
Percent error of the measurement ≈ 21.0
So, the percent error of the measurement, to the nearest tenth of a percent is
Answer:
B -4/5
Step-by-step explanation:
The slope of line D is given by
m = (y2-y1)/(x2-x1)
= (6-1)/ (5-1)
=5/4
We want the slope of the line perpendicular
That would be the negative reciprocal
- (4/5)
Answer: The answer to the question "What portion of the whole snack does each friend get?" is: Tasha 1/2 of the snack, her friends 1/4 of the snack each one.
Step-by-step explanation:
The complete snack is 1. If you say that Tasha eats half of the snack that means that you must divide 1 in 2 parts. Then, that gives us 1/2 left.
Tasha gives 1/2 of the snack to her 2 friends and shares it equally. That means that again you must divide it in 2 parts. That gives us:
1/2 ÷ 2 = 4
When you divide a fraction (1/2) into an entire number (2) you must take into account that there is a 1 below the entire number (2). Having that in mind, the next step is to multiply in cross: the 1 above the 2 (1/2) will multiply the 1 below the 2 (2/1), And the 2 below the 1 (1/2) will multiply the 2 above the 1 (2/1). The result of the first multiplication will be the number above the fraction that means 1, and the result of the second multiplication will be the number below the fraction that means 4. The final result is 1/4 (look in the picture attached).
To conclude, each of her friends received 1/4 of the snack.
Attached you may find a picture of the parts of the snack that each friend received.

Step-by-step explanation:
A term is a single mathematical expression. It may be a single number (positive or negative), a single variable ( a letter ), several variables multiplied but never added or subtracted. Some terms contain variables with a number in front of them.
Distance between home and school(on map)=5cm
every 4cm=8km
therefore distance between home and school=
5/4×8 = 1.25×8 = 10km
