Step-by-step explanation:
Imagine you measure the length of 15 cars, and then sum that length, in order to see how big a parking lot must be. You do this in two different ways. First, you use the same bad tape measure for each car so that your measurement is always 1 cm too long, or always too short, for all of the measurements. For your second attempt, you use a different bad tape measure for each car, so there is an uncertainty of plus or minus 1cm in each measurement. What is your estimate of the total error in the sum of all the car lengths in these two cases
Answer:
± 15 cm
Step-by-step explanation:
In the first case, since the measurement is 1 cm too long or too short, the error is ± 1 cm.
In the second case, the uncertainty or error is also ± 1 cm.
Now, since there are 15 cars, and there is an error of ± 1 cm in each measurement, by the error formula the total error in the sum of both cases is 15 × ±1 cm = ± 15 cm
So, the total error in both cases is ± 15 cm.

how many pounds of coffee worth $10 a pound should be added to 20 pounds of coffee worth $4 a pound to get a mixture worth $5 a pound
Answer:
4
Step-by-step explanation:
1. if the mass of coffee worth $10 is 'x', then its worth is 10x, and the worth of the mixture is 5(x+20);
2. using the previous item it is possible to write the next equation:
5(x+20)=4*20+10*x; ⇒ x=4.
3. the required mass is 4 pounds.

Step-by-step explanation:
Answer: 50/3 or 16 2/3 or 16.67
Step-by-step explanation:
Given
18-3k÷9
Substitute [k] value into the given expression
18-3k÷9
=18-3(4)÷9 ⇒ Substitute the value
=18-12÷9 ⇒ Expand the parenthesis
=18-4/3 ⇒ First do division
=54/3-4/3 ⇒ Convert an integer into a fraction
=50/3=16 2/3=16.67

a train travels 16 miles in 20 minutes how many minutes would 12 miles be
Answer:Then 16x = 240, and x = 240/16 = 15. It will take 15 minutes to travel 12 miles.
Step-by-step explanation:
16 miles = 12 miles
20 mins. how many mins?
16 = 12 cross multiply 16? = 240 divide by 16 240 divided by 16 = 15 miles
20 ? because 15 x 16 = 240
Answer:
It will take 15 minutes to travel 12 miles.
Step-by-step explanation:
Write and solve an equation of ratios:
16 miles 20 min
----------- = -----------
12 miles x
Then 16x = 240, and x = 240/16 = 15.
I needddd helpppp asappppp
Answer:
Step-by-step explanation:
Part A: Slope of parallel lines are equal.
4x - 3y - 7 = 0 ⇔ y = [tex]\frac{4}{3}[/tex] x - [tex]\frac{7}{3}[/tex]
m = [tex]\frac{4}{3}[/tex]
y - 3 = [tex]\frac{4}{3}[/tex] ( x + 2 ) ⇔ y = [tex]\frac{4}{3}[/tex] x + [tex]\frac{17}{3}[/tex] ⇔ 4x - 3y + 17 = 0
Part B: Slope of perpendicular lines are opposite reciprocal.
[tex]m_{1}[/tex] × [tex]m_{2}[/tex] = - 1
[tex]m_{1}[/tex] = [tex]\frac{4}{3}[/tex]
[tex]m_{2}[/tex] = - [tex]\frac{3}{4}[/tex]
y - 3 = - [tex]\frac{3}{4}[/tex] ( x + 2 ) ⇔ y = - [tex]\frac{3}{4}[/tex] x + [tex]\frac{3}{2}[/tex] ⇔ 3x + 4y - 6 = 0
) A computer program found that the line LaTeX: c=2t-89c = 2 t − 89 is a good fit for the data. Use this equation to predict how many cups of lemonade Lin might sell on a day when the high temperature is 74 degrees. We predict she will sell 40 cups of lemonade.
Answer:
Number of cups of lemonade = 59 cups
Step-by-step explanation:
Given the linear function :
C = 2t - 89
At temperature of 74° ;
The cups of lemonade as calculated using the linear model:
C = 2t - 89 ; where c = cost of lemonade ; t = temperature.
C = 2(74) - 89
C = 148 - 89
C = 59
A function assigns the values. The prediction that she will sell 40 cups of lemonade that day is wrong.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
As it is given that function, c=2t-89, where the number of cups of lemonade is represented by c, and t represents the temperature of the day.
Now, as it is given that the temperature at the day is 74, therefore, the number of cups that will be sold that day can be predicted as,
[tex]c = 2t-89\\\\c = 2(74)-89\\\\c = 148-89\\\\c = 59[/tex]
Hence, the prediction that she will sell 40 cups of lemonade that day is wrong.

Question 1: What is the solution to the system of equations? ( Look at the picture) Answer part A and Part B. ( Will Mark Brainliest).
Answer:
x-2y= -8
Step-by-step explanation:
Answer:
Step-by-step explanation: Part A:
3x−6y=−12;x−2y=−8
Rewrite equations:
x−2y=−8;3x−6y=−12
Step: Solvex−2y=−8for x:
x−2y=−8
x−2y+2y=−8+2y(Add 2y to both sides)
x=2y−8
Step: Substitute2y−8forxin3x−6y=−12:
3x−6y=−12
3(2y−8)−6y=−12
−24=−12(Simplify both sides of the equation)
−24+24=−12+24(Add 24 to both sides)
0=12
Answer:
No solutions.
Part B: the lines are parallel
