Answer:

250 km.

Step-by-step explanation:

Alright, so for this problem we can split it into two parts. Since distance = speed*time, the first 3 hours give us 3*40 or 120 km, and the last 2 hours give us 2*65, or 130 km. Adding these together, we get a final distance of 250 km.

The teacher asked 4 students to measure 4 different objects. The table shown represents their measurements. Which student had th
Maru [420]

Student 4 has the largest percent error.

Step-by-step explanation:

The percent error of a measurement is given by

p=\frac{|x-x_{true}|}{x_{true}}\cdot 100

where

x is the value of the measurement

x_{true} is the actual value

For student 1:

x=49\\x_{true}=50

Percent error:

p=\frac{|49-50|}{50}\cdot 100=0.02\cdot 100=2\%

For student 2:

x=25.5\\x_{true}=25

Percent error:

p=\frac{|25.5-25|}{25.5}\cdot 100=0.0196\cdot 100 = 1.96\%

For student 3:

x=7.5\\x_{true}=8

Percent error:

p=\frac{|7.5-8|}{8}\cdot 100=0.0625\cdot 100 = 6.25\%

For student 4:

x=2.1\\x_{true}=1.6

Percent error:

p=\frac{|2.1-1.6|}{1.6}\cdot 100=0.3125\cdot 100 = 31.25\%

So, student 4 has the largest percent error.

Set up an equation to show (×+2)×5=y
Masteriza [31]
<span>5x+10 = y

Subtract 10 from both sides.

5x = y - 10

Divide both sides by 5.

x = 1/5y - 2

Plugin 1/5y - 2 for the y.
5(1/5y - 2)
1 - 10 + 10 = y

1 = y
<span>
</span><span>Your Answer(s)
</span><span>y = 1
</span></span>x = 1/5y - 2
