Answer: The percent of the estimated time is the actual time is about 14%.
Step-by-step explanation:
As per given,
Actual time of completing the job = [tex]5\dfrac{1}{2}\text{ days}=\dfrac{11}{2}\text{ days}[/tex]
Estimated time for completing the job = [tex]4\dfrac{3}{4}\ \text{days}=\dfrac{19}{4}\ \text{days}[/tex]
The percentage error is given by:-
[tex]\%\text{ error}= \dfrac{|\text{Estimated-Actual}|}{\text{Actual}}\times100[/tex]
[tex]=\dfrac{|\dfrac{19}{4}-\dfrac{11}{2}|}{\dfrac{11}{2}}\times100\\\\\\=\dfrac{|\dfrac{19-22}{4}|}{\dfrac{11}{2}}\times100\\\\\\=\dfrac{|\dfrac{-3}{4}|}{\dfrac{11}{2}}\times100\\\\\\=\dfrac{\dfrac{3}{4}}{\dfrac{11}{2}}\times100\\\\\\=\dfrac{3\times2}{11\times4}\times100\\\\\approx14\%[/tex]
The percent of the estimated time is the actual time is about 14%.

Step-by-step explanation:
What is the value of s?
Answer:
s = 4
Step-by-step explanation:
x is a supplementary angle or 3d angle of the triangle.
(33s - 38) + x = 180 as supplementary angles.
(4s + 43 )+ 35 + x = 180 as angles of the triangle.
(33s - 38) + x = (4s + 43 )+ 35 +x
33s - 38 = 4s + 43 + 35
33s - 4s = 43 + 35 + 38
29s = 116
s = 4
PLZ ANSWER FAST 18 points Which of the following sets of numbers represents the side lengths of a right triangle?
A){10,5,12}
B){1,2,3}
C){2,4,5}
D){14,48,50}
Answer:
D is the awnser
Step-by-step explanation:
i got the awsner because i first got the highest number which is 50 then i did 14^2 which is 196 then i did the same with the 48^2 2304 so then i added 2304 and 196 and got 2,500 then i did the square root and got 50 so the highest number would be the 2 nubers squared so the awnser is D
An ant needs to travel along a 20cm × 20cm cube to get from point A to point B. What is the shortest path he can take, and how long will it be (in cm)?
Answer:
1. Along a diagonal, and then along an edge.
2. 48.28 cm.
Step-by-step explanation:
Assume points A and B are at diagonally opposite corners, as in the diagram below.
1. Shortest path
The shortest path is to go along the diagonal AC and continue along the edge CB.
2. Distance
The distance travelled is
d = AC + CB
According to Pythagoras,
AC² = AD² + CD² = 20² + 20² = 400 + 400 = 800
AC = √800 = 20√2
d = AC + CB = 20√ 2+ 20 ≈ 2 × 1.414 + 20 = 48.28 cm
The ant travels 48.28 cm.

3, 3, 4, 5, 5,9
The mean
the median. is it greater than, is less than or is equal to
Answer:
is greater than
Step-by-step explanation:
Mean: sum of numbers ÷ how many numbers there are
3 + 3 + 4 + 5 + 5 + 9 = 29
29 ÷ 6 = 4.83333
Median: middle number
3 3 4 5 5 9
4 + 5 = 9
9 ÷ 2 = 4.5
4.83333 > 4.5 so the mean is greater than the median.

What are the domain and range of f(x) = 4x – 8? A. domain: {x | x is a real number}; range: {y | y > –8} B. domain: {x | x is a real number}; range: {y | y > 8} C. domain: {x | x > 4}; range: {y | y > –8} D. domain: {x | x > –4}; range: {y | y > 8}
Answer: Non of the options is correct.
Step-by-step explanation:
Domain of a function are the minimum and maximum values of independent variable (x).
You are given the function:
f(x) = 4x – 8
The domain can be any real numbers.
Range is the minimum to maximum value of dependent variable ( y )
From the given equation:
f(x) = 4x – 8
If the value of domain are substituted, the range will also be any real numbers.
Non of the answers is correct because both the domain and the range are all real numbers.
But the best option among the given option is option A:
domain: {x | x is a real number}; range: {y | y > –8}

Need help finding the missing length to the attached triangle.
Answer:
x = 60
Step-by-step explanation:
All 3 right triangles are similar, thus ratios of corresponding sides are equal.
[tex]\frac{x}{144}[/tex] = [tex]\frac{25}{x}[/tex] ( cross- multiply )
x² = 3600 ( take the square root of both sides )
x = [tex]\sqrt{3600}[/tex] = 60

Answer:
it is about 34 days
Step-by-step explanation:
divide the weight by the age for each kitten, you have a number called H
for example: kitten 1 has H1 = 600/50=12, kitten has H2 =340/28=85/7,kitten 3 has H3= 480/42= 80/7,...
find the arithmetic mean K of those number
K = (H1+H2+...+H8)/8 ≈ 13,44
so the age of the abandoned kitten is 460/13,44 ≈ 34,2 days

Answer:
t and u are parallel lines
s and t are also parallel lines
Step-by-step explanation:
If two parallel lines are cut by a transversal ,
then in it
pair of alternate angle are equals, similarly vice versa
if pair of alternate angle are equals then lines are parallel
pair of corresponding angles are equal and vice-versa
for example
in the given problem
if line t and u are parallel (note we have assumed this to give example of parallel lines)
then angle 7 and 9 are called alternate angles
pair of angles 5 and 9 are corresponding angles.
________________________________________________
given
∠8 = ∠10 which are alternate angles for line t and u and s is transversal for it,
thus t and u are parallel lines
___________________________
∠1 = ∠3 as they vertically opposite angles
and we know that pair of vertically opposite angles are equal
given
∠1 = ∠7
thus
∠3 = ∠7
as pair of angles ∠3 and ∠7 are corresponding angles. and are equal and hence line s and t are also parallel.

The volume of cone and cylinder are same or equal, so they are equal is correct.
What is Three dimensional shape?a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
There are two figures one is cone and other is Cylinder.
The volume of cone can be find by using πr²h/3
r=5, h=6
Volume = π(25)(6)/3
=50π
Now to find volume of cylinder.
h=50 and r=1
Volume = πr²h
=50π
the volumes are same for both cylinder and cone.
Hence, the volume of cone and cylinder are same or equal, so they are equal is correct.

Step-by-step explanation:
Find the number of 4-digit numbers that contain at least three even digits.
Answer:
4625 numbers
Step-by-step explanation:
To solve this problem we can separate it in different cases, and then we sum the amount of numbers of each case to find our final result.
The first case is: all four numbers are even.
We have 5 even digits, and the first digit of the 4-digit number can't be zero, so for the first digit we have 4 possible values, and for the other 3 digits we have 5 possible values, then the amount of numbers with this condition is:
[tex]N_1 = 4 * 5 * 5 * 5 = 500\ numbers[/tex]
The second case is the number having three even digits and one odd digit, and the first digit is the odd digit.
In this case, the first digit has 9 possible values (all digits but zero) and the other 3 digits have 5 possible values (even digits):
[tex]N_2 = 9 * 5 * 5 * 5 = 1125\ numbers[/tex]
The third case is the number having three even digits and one odd digit, and the first digit is not the odd digit.
In this case, the first digit has 4 possible values, the odd digit has 10 possible values and the other two digits have 5 possible values. The odd digit can be the second, the third or the fourth digit, so we multiply our result by 3 (because we will find the same result if we choose the odd digit to be the second, third or fourth):
[tex]N_3 = 3 * 4 * 10 * 5 * 5 = 3000\ numbers[/tex]
So the final result is the sum of these cases:
[tex]N = N_1 + N_2 + N_3[/tex]
[tex]N = 500 + 1125 + 3000 = 4625\ numbers[/tex]
Can you please say if the point is on the line?
