Mr. West estimated a mass to be 265g, but upon carefully measuring it, found the actual mass to be 240g. What was the percent error?
Answers
Answer:
The answer is 10.42 %Step-by-step explanation:
The percentage error of a certain measurement can be found by using the formula
[tex]P(\%) = \frac{error}{actual \: \: number} \times 100\% \\ [/tex]
From the question
actual mass = 240 g
error = 265 - 240 = 25
So we have
[tex]p(\%) = \frac{25}{240} \times 100 \\ = 10.41666666...[/tex]
We have the final answer as
10.42 %Hope this helps you

. During a volleyball training session, Idalie drank twice as much water as Adamaris, and Jonathan
Arank 100 mL more water than Idalie. Between them they drank 3 liters of water. How much water
did Adamaris drink?
Answers
Answer:
Step-by-step explanation:
Let's say I = amount of water Idalie drank,
A = amount of water Adamaris drank
J = amount of water Jonathan drank.
We are told Idalie drank twice as much water as Adamaris. You can write it as:
Idalie = 2 times Adamaris
I = 2A
Then we are told Jonathan drank 100ml more than Idalie. So
Jonathan = 100 + Idalie
J = 100 + I (and we know I = 2A)
J = 100 + 2A
Between them they drank 3 liters (3L = 3000ml) of water.
Idalie + Adalie + Jonathan = 3000
I + A + J = 300
So since we know I = 2A and J = 100 + 2A, we can put it into the equation above:
2A + A + 100 + 2A = 3000
Gather the like terms and you get:
5A + 100 = 3000
Subtract 100 from both sides.
5A = 3000 - 100 = 2900
To find A, divide both sides by 5
A = 2900/5 = 580
This means Adamaris drank 580ml of water

what is the simplification for this ? 2y+3=4y+2
Answers
Answer:
2y-1
Step-by-step explanation:
Answer: y = 1/2 in decimal form = 0.500
Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
2*y+3-(4*y+2)=0
olve : -2y+1 = 0
Subtract 1 from both sides of the equation :
-2y = -1
Multiply both sides of the equation by (-1) : 2y = 1
Divide both sides of the equation by 2:
y = 1/2 = 0.500

We move all terms to the left:

We add all the numbers together, and all the variables
-(11x-13)+20=0
We get rid of parentheses
-11x+13+20=0
We add all the numbers together, and all the variables

We move all terms containing x to the left, all other terms to the right

20=11x-13 Add 13 on both sides.
+13 +13
33=11x Divide both sides by 11.

Jerome hiked three-fourths of a mile in two-thirds of an hour. What was his hiking speed in miles per hour?
Answers
The value of his hiking speed in miles per hour will be;
⇒ Speed = 9/16 miles per hour
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Jerome hiked 3/4 of a mile in 2/3 of an hour.
Now,
Since, Jerome hiked 3/4 of a mile in 2/3 of an hour.
Hence, We can formulate;
⇒ Speed = Distance / Time
⇒ Speed = 3/4 / 2/3
⇒ Speed = 3×3 / 4×4
⇒ Speed = 9/16 miles per hour
Thus, The value of his hiking speed in miles per hour will be;
⇒ Speed = 9/16 miles per hour
