Brad expected that a jar will hold 252 grams of powder, but the label shows that it contains 240 grams of powder. Calculate the percent error
Answer:
4.76%
Step-by-step explanation:
A jar will hold 252 grams of powder
The label shows that its contains 240 grams
Therefore the percent error can be calculated as follows
= 240-252/252 × 100
= -12/252 × 100
= 0.0476 × 100
= 4.76%
Hence the percent error is 4.76%

Answer:
see attachments
Step-by-step explanation:
The side lengths are found using the distance formula.
d = √((x2-x1)^2 +(y2-y1)^2)
For example, the length of RS in the first triangle is ...
d = √((4-(-1))^2 +(4-(-3))^2) = √(25 +49) = √74 ≈ 8.602
This same computation is used for all of the sides of the triangles. When the same tedious computation is repeated over and over, I like to use a spreadsheet to do it. In the attached spreadsheet the two points used are the one on the same line as the distance, and the one on the line below. Side lengths are shown in the attachment to 3 decimal places.
__
In order to classify the triangle as acute, right, or obtuse, we can compare the side lengths to those of a right triangle. For the purposes of computation in a spreadsheet, it is convenient to compute the middle length side of a right triangle that has the same longest and shortest sides as the triangle we have.
If the computed side is longer than the actual middle side, then the triangle we have is obtuse. If it is shorter, the triangle we have is acute. If it is exactly the same, then the triangle we have is a right triangle.
In every case here, the computed middle side is shorter than the actual middle-length side, so all of the triangles are acute triangles. (The one of problem 39 is isosceles, since two sides are the same length. The others are scalene.)

The triangles are graphed in the second attachment.

to the right side and solve.
x

20
−
2
y
Answer:
r = 10
y = 11
Step-by-step explanation:
4y = 40 + 4
4(r + 1) = 40 + 4
4(r) + 4(1) = 40 + 4
4r + 4 = 40 + 4
4r + 4 = 44
4r + 4 - 4 = 44 - 4
4r = 40
4r ÷ 4 = 40 ÷ 4
r = 10
-----------------------------------------
y = r + 1
y = (10) + 1
y = 11
-----------------------------------------
4y = 40 + 4
4(11) = 40 + 4
4(11) = 44
44 = 44

Answer:
Shifted by 6 units left on the x-axis.
Step-by-step explanation:
Given function is,
f(x) = 5ˣ + 1
After transformation, this function becomes g(x) = [tex]5^{(x+6)}+1[/tex]
Here, g(x) = f(x + 6)
By the rule of transformation,
Function 'f' has been shifted by 6 units left on the x-axis to form a new function 'g'.

9. A team of 8 basketball players need to choose a co-captain and captain.
A) combination
B) permutation
C) neither
Answer:
b
Step-by-step explanation:
Since the order is important, as there are different roles, a permutation is used, hence option B is correct.
When to use the combination and the permutation formula?If the order in which the options are taken is important, permutation is used.Otherwise, if the order in which the options are taken is not important, combination is used.In this problem:
If the order is LeBron and Giannis, LeBron is the co-captain and Giannis is the captain.If it is Giannis and LeBron, Giannis is the co-captain and LeBron is the captain.Hence the order is important, which means that it is a permutation.

The song lasts 3 minutes and 27 seconds. If Rasmus' beloved has to get home before the song is over, and rides a bike at an average speed of 15 km / h, how far away must her work be from their home?
Set up an equation that describes the problem where x is the distance between home and work.
Answer:
Kindly check explanation
Step-by-step explanation:
From the question :
Duration, time, t = 3 minutes, 27 seconds = (3 * 60) + 27 = 207 seconds
Average speed = 15 km/h = (15*1000) /3600 = 4.16666 m/s
Let distance = x
Recall:
Speed = distance / time
Distance = speed * time
x ≤ (speed * time)
x ≤ (4.16666 * 207)
x ≤ 862.5 m
x ≤ (862.5 / 1000) km
x ≤ 0.862.5 km

I will do it in a way that can solve all these kinds of problem.
Of course, you can just substitute every possible answer in and see which one has the highest y value.
BUT I'm going to do this question by completing the square.
First organize the equation by decreasing degrees.
y=-16t^2+32t
Now factor out a -16 to make the x variable have no coefficient.
y=-16(t^2-2t)
Now complete the square.
y=-16(t-1)^2+16
By this if you graph it its the parent graph y=x^2, its a reflection over x axis by the negative sign at the beginning, then a vertical stretch by 16, and then go to the right by 1 then up by 16. This meant that the vertex is (0,0) go right 1 and up 16.
The vertex or the highest point of the graph is point (1,16) This also meant that its after 1 second at 16 feet height. The answer is B.

Bentley had $40 in birthday money in her piggy bank. She spent $10 on new flip-flops, then got $20 for her allowance and did not spend any of that money for 1 week. Finally, she spent $15 on new sunglasses.
Which part of the scenario is best represented by a linear increasing interval?
A. Bentley has $40 in her piggy bank.
B. Bentley spent $10 on new flip flops.
C. Bentley got $20 for her allowance.
D. Bentley spent $15 on sunglasses.
Answer:
C. Bentley got $20 for her allowance.
Step-by-step explanation:
If Bentley was given $40 at first, then spent $10, we plot a line on the graph that decreases and then she receives $20. $20 is bigger than $10, therefore this is the scenario best represented by a linear increasing interval.
I hope this makes sense!! ^-^
A circular swimming pool has a radius of 3.5 m Liz is placing a piece of rope around the edge of the pool if Liz has exactly enough rope, which measurement is the closest to the length of the piece of rope in meters
Answer:
the length of the piece of rope in meters is 22
Step-by-step explanation:
The computation of the length of the piece of rope in meters is shown below:
= 2πr
= 2 × 3.14 × 3.5m
= 21.98
= 22 meters
Hence, the length of the piece of rope in meters is 22
