Step-by-step explanation:
25.4
The average time Janette to fold and put away all four items is 25.35 seconds. Then the correct option is C.
What is Mean?The mean of average is the ratio of the sum of observations and the number of observations.
Janette was timed by a store manager as she folded and stored a scarf, a shirt, a pair of trousers, and a jumper. Her time for the shirt was 26.1 seconds, the jumper 24.3 seconds, the trousers 32.8 seconds, and the scarf 18.2 seconds.
The average time Janette to fold and put away all four items will be given as,
Average = (26.1 + 24.3 + 32.8 + 18.2) / 4

The entire graph of the function g is shown in the figure below. Write the domain and range of g as intervals or unions of intervals.
Answers
Answer: D = {-5 ≤ x ≤ -2 or 1 ≤ x < 5}
Step-by-step explanation:
When we have a function f(x) = y, the domain is defined as all the possible values of x that the function maps into other values.
In our graph, we can see two curves.
The first one (the one at the left)
Has two black dots, one at x = -5, and other at x = -2
(black dots means that the value is included, white dots means that the value is not included)
So this first part of the domain is:
-5 ≤ x ≤ -2.
Now, the second part has a black dot in x = 1, and a white dot in x = 5, so we can write this part of the domain like:
1 ≤ x < 5
Then the domain of our function is:
D = {-5 ≤ x ≤ -2 or 1 ≤ x < 5}

The height of the person in inches by unit conversion will be 66 inches.
What is unit conversion?To convert any unit into another is called a unit conversion.
In order to convert units, we need to care about their dimensions their dimension should not be changed.
It is known that,
1 feet = 12 inches
Multiply both sides by 5.5
5.5 feet = 12 x 5.5 = 66 inches

A rectangle has an area of 24 square inches. If the side
lengths of the rectangle are integers, which of the
following could be the perimeter of this rectangle?
Answers
Answer:
Possible perimeters:
50 inches, 28 inches, 22 inches, 20 inches.
Step-by-step explanation:
Given that:
Area of triangle = 24 square inches
Side lengths of rectangle are integers.
To find:
Possible perimeter of this rectangle = ?
Solution:
Here, options are missing, so let us calculate all possibilities for the perimeter.
The formula for Area of a rectangle is given as:
[tex]A = Length \times Width[/tex]
Let us make integer factors of 24 first of all.
[tex]24 = 1 \times 24\\24 = 2 \times 12\\24 = 3 \times 8\\24 = 4 \times 6[/tex]
These are the four possibilities of length and breadth.
Let us calculate the possible perimeter for each case using the formula for perimeter:
[tex]Perimeter = 2\times (Length + Width)[/tex]
1st possible option:
[tex]Perimeter = 2\times (1+ 24) = 50\ inches[/tex]
2nd possible option:
[tex]Perimeter = 2\times (2+ 12) = 28\ inches[/tex]
3rd possible option:
[tex]Perimeter = 2\times (3+ 8) = 22\ inches[/tex]
4th possible option:
[tex]Perimeter = 2\times (4+ 6) = 20\ inches[/tex]

2×( 1 1/2 – x) is the same as 2 1/3+ 1/15. x=?
Answers
Answer:
x = 3/10
Step-by-step explanation:
2 1/3 = 2 + 1/3 = 6/3 + 1/3 = 7/3
1 1/2 = 1 + 1/2 = 2/2 + 172 = 3/2
2(1 1/2 - x) = 7/3 + 1/15
2(3/2 - x) = 35/15 + 1/15
2*3/2 + 2*-x = 36/15
3 - 2x = 36/15
-2x = 36/15 - 3
-2x = 36/15 - 45/15
-2x = -9/15
x = (-9/15)/-2
x = -9 / (15*-2)
x = 9/30
x = 3/10
verify:
2(3/2 - 3/10) = 36/15
2*3/2 + 2*-3/10 = 36/15
3 - 6/10 = 36/15
30/10 - 6/10 = 36/15
24/10 = 36/15 = 72/30
The ratio of the number of boys and girls in a college is 7 : 8. If the percentage increase in the number of boys and girls be 20% and 10% respectively, what will be the new ratio?
Answers
Answer:
21 : 22
Step-by-step explanation:
Boys : Girls = 7 : 8
Let the number of boy = 7x
the number of girls = 8x
Number of boys after 20% increase = 120% of 7x
= 1.2 * 7x
= 8.4 x
Number of girls after 10% increase = 110% of 8x
= 1.1 * 8x
= 8.8x
After increase in number of boys & girls ,
= 8.4x : 8.8x
= 84 : 88 { reduce to simplest form by giving by 4th table}
= 21 : 22

an online retailer charges $6.99 plus $0.55 per pound to ship electronics purchases. How many pounds is a dvd player for which a shipping charge is $11.94?
Answers
Answer:
The weight is 9 lbs
Step-by-step explanation:
flat fee + price per found * pounds = total charge
6.99 + .55 * p = 11.94
Subtract 6.99 from each side
6.99 + .55 * p - 6.99= 11.94-6.99
.55p =4.95
Divide each side by .55
.55p/.55 = 4.95/.55
p =9
The weight is 9 lbs

Answers
Answer:
k = 3Step-by-step explanation:
The vertex is (d, e)
for quadratic function: f(x) = ax² + bx + c we have:
d = -b/a and d = (x₁ + x₂)/2
a = 1, b = k, x₁ = -4, x₂=-2
so:
d = -b/a = -k/1 = -k and d = (x₁ + x₂)/2 = (-4-2)/2 = -3
-k = -3

Step-by-step explanation:
The area of the square frame is the area of the inner square subtracted from the area of the outer square
Which gives;
52.2² - 47.8² = 440
Therefore;
Option A. 52.2² - 47.8² is a correct way of finding the area of the square frame
Option B. 2 × ((52.2×2.2) + (47.8×2.2)) = 440, is a correct way of finding the area of the square frame
Option C. 52.2 × 4.4 × 2 + 47.8 × 4.4 × 2 = 880, is not a correct way of finding the area of the square frame
The error is the thickness is 2.2 not 4.4
Option D. 100×(52.2 - 47.8) = (52.2 + 47.8) × (52.2 - 47.8) = 52.2² - 47.8² = 440, is a correct way of finding the area of the square frame

Which statement is a theorem? A) Three noncollinear points determine a plane. B) Through any two points there is exactly one line. C) A rectangle is a parallelogram with four right angles. D) If C lies on AB and is between A and B, then AC + CB = AB.
Answers
Answer:
D) If C lies on AB and is between A and B, then AC + CB = AB.
Step-by-step explanation:
Statements A, B and C are postulates while statement D is a theorem.
A postulate is a statement that is true but cannot be proven, but a theorem is a statement that can be proven.
The statement D is the betweenness theorem for points. It states that If C lies on AB and is between A and B, then AC + CB = AB.
This statement can be proven, so it is a theorem.

Write an equation for the nth term of the arithmetic sequence. Then find a50.
8, 2, -4, - 10,
Answers
Explanation:
Write an equation for nth term:
a + d(n - 1)
a = 8 (first term)
d = -6 (common difference)
8 - 6(n - 1)
= 8 - 6n + 6
= -6n + 14
Find a 50:
-6(50) + 14
= -300 + 14
= -286
The equation for the nth term of the arithmetic sequence is -6n + 14 and the found 50 is -286.
What is an arithmetic sequence?An arithmetic sequence is a series of numbers that are ordered and share a common difference between each succeeding term. In the arithmetic sequence 3, 9, 15, 21, 27, for example, the common difference is 6.
Arithmetic is the branch of mathematics that studies numbers by performing various operations on them. A sequence is a numerically ordered list. The three dots indicate that the pattern should be continued. The difference is six.
a + d(n - 1)
a = 8 (first term)
d = -6 (common difference)
8 - 6(n - 1)
= 8 - 6n + 6
= -6n + 14
Find a 50:
-6(50) + 14
= -300 + 14
= -286
Therefore, the equation for the nth term of the arithmetic sequence is -6n + 14.
