Answer:

<em>Chase had a 6.3% error</em>

Step-by-step explanation:

<u>Percent Error</u>

If the real measure of a certain magnitude is M and the experimental measure is N, then the error is N-M.

To express that difference as a percentage, we divide by the real measure:

\displaystyle pct=\frac{N-M}{M}\cdot 100\%

The actual length of the line is M=9.5 inches, but Chase measured N=8.9 inches, thus the percent error is:

\displaystyle pct=\frac{8.9-9,5}{9.5}\cdot 100\%

\displaystyle pct=\frac{-0.6}{9.5}\cdot 100\%

pct = -6.316%

To the nearest tenth:

pct = -6.3%

Chase had a 6.3% error

the driveway in front of the brown house is 35 feet long and the driveway of the red house is 7 yards and 9 feet long. which hou
Zigmanuir [339]

Answer:

The brown house has the longer driveway

Step-by-step explanation:

So we would need to convert both of these units of measurements to feet in order to compare them.

  • There are <u>3 feet in 1 yard</u>

Converting yards to feet, wee need to multiply the number of yards by 3

  • 7 yards = 21 feet

Since the red house has a driveway of 7 yards and 9 feet, we can rewrite this to 21 feet + 9 feet, which is equivalent to 30 feet

Now comparing the two driveways, the 35 ft-long brown driveway is 5 feet longer than the 30 ft-long red driveway.

The brown house has the longer driveway

Check 2. The circumference of a circle is C centimeters. The diameter of the circle is 6 centimeters. Write an expression that r
Anna11 [10]

Answer:

radius of circle = 3cm

circumference = 18.84cm

diameter = 6cm

Step-by-step explanation:

if the diameter of circle is 6cm

radius of circle = diameter/2

                         = 6/2

                         = 3

circumference of circle = 2\pir

                                       = 2 x 3.14 x 3

                                       = 6.28 x 3

                                       = 18.84

What is the volume of this oblique cone?
Citrus2011 [14]

Volume of the oblique cone: 432π cm³

Step-by-step explanation:

The volume of a cone is given by:

V=\frac{1}{3}bh

where

b is the area of the base

h is the height

The area of the base can be written as

b=\pi r^2

where r is the radius of the base. Substituting into the 1st equation,

V=\frac{1}{3}\pi r^2 h

For the cone in this problem, we have:

r = 9cm\\h = 16 cm

Substituting into the formula, we find the volume:

V=\frac{1}{3}\pi(9^2)(16)=\frac{1}{3}\pi (1296)=432\pi cm^3
