If the car can travel 81 km in one hour, (60 minutes) that means that it can travel 81/60 in a minute. The result is 1.35, and this times 15 will give you the amount the car can travel in 15 minutes. The answer is 20.25km. Then you would divide 20.25 and 15 to get your answer.

A line of 8cm was measured as 8.04cm what is the percentage error

BlackZzzverrR [31]

Answer:

0.5% error

Step-by-step explanation:

We can use the percentage error formula, which is

$\frac{|approx-exact|}{exact}\cdot100$ .

We know that the approximated value was 8.04, however it is actually 8cm, so we can substitute inside the equation.

$\frac{|8.04 - 8|}{8}\cdot100 \\\\\frac{0.04}{8}\cdot100 \\\\0.005\cdot100 \\\\0.5$

Hope this helped!

What is the amplitude of the function ?

koban [17]

Answer:

Step-by-step explanation:

First, find the midline by averaging the highest value (2) and the lowest value (-4). In other words, do (2+-4)/2. You get the midline as -1. Now find the distance from the midline to the top. Distance from -1 to 2 is 3. Amplitude is therefore 3.

How do you solve 3x-100=1x+50

frutty [35]

Answer:75

Step-by-step explanation:First isolate x by getting rid of the 100 so the equation becomes 3x=x +150 then you subtract x From both sides so it’s 2x=150 then divide by two on both sides so you get X = 75
