Li enters a competition to guess how many jelly beans are in a jar.
Li’s guess is 345 jelly beans.
The actual number of jelly beans is 300
.What is the percent error of Li’s guess?
Answers
Answer:
15% 15%
Step-by-step explanation:
it was correct for me
The percent error of Li’s guess is 15%
What is the absolute error?"It is the absolute difference between an observed value and the actual value."
What is the relative error?"It is the ratio of the absolute error of the measurement to the actual value."
What is the percent error?"It is the relative error multiplied by 100."
For given example,
Li’s guess is 345 jelly beans.
observed value (E) = 345
The actual number of jelly beans is 300
actual value (A) = 300
So, the absolute error is,
Absolute error = |E - A|
= | 345 - 300|
= 45
Now, we find the relative error of Li's guess.
Relative error = 45 ÷ 300
Relative error = 0.15
The percent error is,
0.15 × 100 = 15%
Therefore, the percent error of Li’s guess is 15%

Which equation has the same solution as 7x−14=21?
Answers
Answer:
2x=10
Step-by-step explanation:
7x-14=21
x=5
2x=10 (divide both sides by two)
2x/2 10/2
x=5
Yky. we'd to provide the other options but to do this you need to +14 to both side. 21+14 then -14+14 cancel. so it's now
7x=35 then you divide 7 in both sides 7 cancels 35/7 =5
x=5

There were 40 cookies to start with. If Mrs. Lettings class at 1/2 of the cookies, there are now 20 cookies left. Mrs Kim’s class then ate 1/4, because 1/4 of 40 is 10, then they ate 10 cookies. So there are now 10 cookies left
Can some one help in thsi with the steps required
Answers
Answer: 24.5 m² ( area)
Step-by-step explanation:
See , Total area of wall is given - length , 6m - width/breadth , 5m
so , Area of total wall = l x b = 6*5 = 30m²
so , there is a window whose length is 2 meters and breadth/width of 0.5m
so , Area of window = l x b = 1m²
So , area of door = length , 3 - Width/breadth- 0.5 m²
So , Area of door = 3* 1.5 = 4.5
Then the question wants us to find the area of the wall without counting window and door . So we can subtract the area of door and window from the area of the whole wall to get the area of the wall without the window and door .
= total area of wall - area of window and door
30m²-1m²-4.5
So as a result , we get a total area of the wall without the window and door to be painted as 24.5m²

The exterior angles of a triangle add up to 360. You know two of them. Therefore you can find w.
125 + 90 + w = 360 Combine like terms on the left
215 + w = 360 Subtract 215 from both sides
w = 360 - 215 Combine
w = 145
Two.
The polygon has 4 exterior angles. They too should add up to 360.
88 + x + 108 + 115 = 360 Combine the left had side
x + 311 = 360 Subtract 311 from both sides
x = 360 - 311 Combine
x = 49
What have you learned? You should notice that all polygons have exterior angles that add up to 360

The science club fires a rocket up into the air.
The height (h) of the rocket, in feet above the ground,
is modeled by the formula h=400t−16t2, where t is the time in

How many seconds will it take for the rocket to fall to the ground?
Find the value of t, rounded to the nearest tenth.
[how many seconds it took for the rocket to hit the ground].
t =
Answers
The height of an object can be represented as a function of time.
It takes the rocket 25 seconds to hit the ground
The height function is given as:
[tex]\mathbf{h(t) = 400t - 16t^2}[/tex]
When the rocket hits the ground, we have:
h(t) = 0
So, the height function becomes
[tex]\mathbf{ 400t - 16t^2 = 0}[/tex]
Rewrite as:
[tex]\mathbf{ 16t^2 = 400t}[/tex]
Divide both sides by 16t
[tex]\mathbf{ t = 25}[/tex]
Hence, it takes the rocket 25 seconds to hit the ground

Step-by-step explanation:
Find Slope and Y intercept
Slope and Y intercept
x+y=-2<-- subtract x to get y alone
y=-x-2
Thus slope is 1/1 or 1
and y intercept is -2
Answer:
-1
Step-by-step explanation:
y=mx+c m=slope
c=y intercept
y=-x+2
so the slope is -1 and intercept of 2
Does the point (4, 10) satisfy the inequality y greater than or equal to 2x + 2?
Answers
Answer:
Yes, the point (4,10) satisfies the inequality.
Step-by-step explanation:
In order to answer this question, we can plug the values x = 4 and y = 10 into the inequality:
y ≥ 2x + 2
10 ≥ 2(4) + 2
Then solve:
10 ≥ 8 + 2
10 ≥ 10
Since the value 10 is greater than or equal to itself, the inequality is true at the point (4,10).

The number of boxes required to hold 1000 cans is 100 bags.
What is the unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given that, every Monday each student brings in a bag with 10 cans.
They put 10 bags into a box.
So, number of boxes required to hold 1000 cans
= 1000/10
= 100 bags
Therefore, the number of boxes required to hold 1000 cans is 100 bags.
