when measuring the radius of a sphere an error of 0.6% takes place in the measurement. What will be the permiable error while measuirng the surface
Answer:
So, the error is [tex]4.8\pi r[/tex].
Step-by-step explanation:
Error in measuring the radius = 0.6 %
Let the radius is r.
The surface area of sphere is
[tex]S= 4\pi r^2\\\\dS = 4 \pi\times 2 r dr\\\\dS =8\pi r \times 0.6 = 4.8\pi r[/tex]

A school fair ticket costs $8 per adult and $1 per child. On a certain day, the total number of adults (a) and children (c) who went to the fair was 30, and the total money collected was $100. Which of the following options represents the number of children and the number of adults who attended the fair that day, and the pair of equations that can be solved to find the numbers?
20 children and 10 adults
Equation 1: a + c = 30
Equation 2: 8a + c = 100
10 children and 20 adults
Equation 1: a + c = 30
Equation 2: 8a − c = 100
10 children and 20 adults
Equation 1: a + c = 30
Equation 2: 8a + c = 100
20 children and 10 adults
Equation 1: a + c = 30
Equation 2: 8a − c = 100
Answer:
a + c = 30
8a + c = 100
a=10, c= 20
Step-by-step explanation:
cost = 8a + 1c since it is 8 dollars for adult and 1 for child where a is the number of adults and c is the number of children
a+c = 30 since we know that 30 adults and children went
100 = 8a + 1c and it cost 100 dollars
Let c =30 -a
100 = 8a + (30-a)
100 = 7a +30
Subtract 30 from each side
70 = 7a
Divide by 7
10 =a
Then a+c = 30
10+c = 30
c = 30-10
c = 20
Answer:
eqn1 : a +c=30
eqn2: 8a+c=100
20 children and 10 adults

Ethan is decorating the outside of a box in the shape of a square pyramid. The figure below shows a net for the box.
Answer:
45.312 cubic cm
Step-by-step explanation:
Since we are not asked what to look for, we can find the volume
volume of the pyramid = 1/3 * Base area * Height
Base area = 4.8 * 4.8 = 23.04 sq. cm
HEight of prism = 5.9cm
Volume of the prism = 1/3 * 23.04 * 5.9
Volume of the prism = 135.936/3
Volume of prism = 45.312 cubic cm
The perimeter of an envelope is 34 inches. It is 11 inches wide. How tall is it?
Answer:
6 inches
Step-by-step explanation:
34
11 + 11 + y + y = 34
22 + 2y = 34
22 - 22 + 2y = 34 - 22
2y = 12
2y ÷ 2 = 12 ÷ 2
y = 6
a number is between 20 and 30 and is three times the sum of its digits. what is the number?
Answer:
The only multiples of 3 between 20 and 30 are 21, 24, and 27. Only 27 satisfies the condition that it is 3 times the sum of its digits.
Step-by-step explanation:
The number between 20 and 30 that is equal to three times the sum of its digits is 27
How to determine the number?The numbers between 20 and 30 are:
21, 22, 23, 24, 25, 26, 27, 28, 29
Add each digit of the numbers and multiply by 3.
So, we have
21 ⇒ 3 * (2 + 1) = 9
22 ⇒ 3 * (2 + 2) = 12
23 ⇒ 3 * (2 + 3) = 15
24 ⇒ 3 * (2 + 4) = 18
25 ⇒ 3 * (2 + 5) = 21
26 ⇒ 3 * (2 + 6) = 24
27 ⇒ 3 * (2 + 7) = 27
28 ⇒ 3 * (2 + 8) = 30
29 ⇒ 3 * (2 + 9) = 33
In the above computation, the true correct term of the sequence is
27 ⇒ 3 * (2 + 7) = 27
Hence, the number is 27

In a ABC shown below, side AC is extended to point D with m Z DAB= (180 – 3x) °, mZ B= (6x – 40) °, and m ZC = (x+20) °.
Whats the measure of angle BAC?
Answer:
60°
Step-by-step explanation:
Given :
DAB= (180 – 3x) °,
mZ B= (6x – 40) °, and
m ZC = (x+20) °.
DAB = mZ B + m ZC ( the exterior angle equal the sum of the two opposite interior angles)
180 - 3x = (6x - 40) + (x + 20)
180 - 3x = 6x - 40 + x + 20
180 - 3x = 6x + x - 40 + 20
180 - 3x = 7x - 20
180 + 20 = 7x + 3x
200 = 10x
x = 200/10
x = 20
Angle B = 6x - 40 = 6(20) - 40 = 120 - 40 = 80
Angle C = x + 20 = 20 + 20 = 40
BAC = 180 - (80 + 40) (SUM OF ANGLES IN A TRIANGLE)
BAC = 180 - 120
BAC = 60°

Express 1.2 km as a percentage of 300 m
Answer:
1.2km is 400% of 300m
Step-by-step explanation:
1 km=1000m
So,1.2 km=1000*1.2=1200m
Let 1.2km(or 1200m) be x% of 300 m
By the problem,
300*x/100 = 1200
Or, 3x=1200
Or,x=1200/3=400
1.2km is 400% of 300m

Step-by-step explanation:
Angles in a triangle add up to 180°. Using this, we can form the following equation:
71° + 50° + 6x - 1 = 180. A simplified version is this: 120° + 6x = 180
Remove 120° from both sides to get:
6x = 60
Divide both sides to get:
x = 10

reflection result in a functioning table? Explain.
9514 1404 393
Answer:
yes
Step-by-step explanation:
A table is a 3-D object. It makes no sense to talk about reflecting it across a point or line. If the table is reflected across a vertical plane, the top will remain "up" and the legs will remain "down".
A glide reflection across a vertical plane will result in a functioning table.

In ΔJKL, the measure of ∠L=90°, JL = 80, KJ = 89, and LK = 39. What is the value of the sine of ∠J to the nearest hundredth
Given:
In ΔJKL, m∠L=90°, JL = 80, KJ = 89, and LK = 39.
To find:
The value of sine of ∠J.
Solution:
In a right angle triangle,
[tex]\sin\theta =\dfrac{Perpendicular}{Hypotenuse}[/tex]
In triangle JKL,
[tex]\sin J =\dfrac{LK}{KJ}[/tex]
[tex]\sin J =\dfrac{39}{89}[/tex]
[tex]\sin J =0.4382[/tex]
[tex]\sin J \approx 0.44[/tex]
Therefore, the value of sine of ∠J is about 0.44.
For the women age 18-24 in HANES2, the average height was about 64.3 inches; the SD was about 2.6 inches. Express each height in standard units. (Decimal form; two places after decimal.) 66 inches:
Answer:
For a height of 66 inches, Z = 0.65.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
The average height was about 64.3 inches; the SD was about 2.6 inches.
This means that [tex]\mu = 64.3, \sigma = 2.6[/tex]
66 inches:
The z-score for a height of 66 inches is:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{66 - 64.3}{2.6}[/tex]
[tex]Z = 0.65[/tex]
For a height of 66 inches, Z = 0.65.
