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
Average = 101.4 / 4
Average = 25.35
The average time Janette to fold and put away all four items is 25.35 seconds. Then the correct option is C.

What is the measure of X
Answer:
X = 67Step-by-step explanation:
The triangles' angles are congruent.
So,
J = H
67 = 67
I = K
X = X
Make the angles add
So,
46 + 67 = 113
Subtract from total
180 - 113 = 67
The angle is 67.Hope this helped,

The two interior angles on one lateral face of a pyramid-shaped
paperweight measure 35° each. What is the measure of the unknown
angle?
Answer:
Option (B)
Step-by-step explanation:
From the property of a triangle,
Sum of all interior angles of the triangle is 180°
By applying this property in the given triangle IHK,
m∠HIK + m∠IKH + m∠KHI = 180°
m∠HIK + 35° + 35° = 180°
m∠HIK = 180° - 70°
= 110°
Therefore, measure of the unknown angle of the given triangle is 110°.
Option (B) will be the answer.
Answer:
As eudora states: B).110 is the correct answer.
The sum of twice a number and seven is 13. Find the number.
Answer:
The answer is 3Step-by-step explanation:
Let the number be x
The statement
twice a number is written as
2x
The sum of twice a number and seven is written as
2x + 7
The result is 13
So we have
2x + 7 = 13
Subtract 7 from both sides
That's
2x + 7 - 7 = 13 - 7
2x = 6
Divide both sides by 2
That's
[tex] \frac{2x}{2} = \frac{6}{2} [/tex]
We have the final answer as
x = 3Hope this helps you

In order to rescue Sela's cat, her mother propped a 19 foot long ladder against a tree at a 42° angle with the ground. How
many feet above the ground was their cat? Round your answer to the nearest tenth of a foot.
Answer:
12.7 feet
Step-by-step explanation:
To solve this question, we use the trigonometric function of Sine
sin θ = Opposite side/Hypotenuse
θ = 42°
Hypotenuse = 19 foot ladder
Opposite side = Distance of the cat from the ground(height of the tree)= unknown
sin 42° = Opposite/19 feet
Opposite = sin 42° × 19
Opposite = 12.713481521 feet
Approximately to the nearest tenth of a foot = 12.7 feet.
Therefore, the cat was 12.7 feet above the ground.

4x-1=4x+7 regroup/ divide by the number next to x
Answer:
x = ∞Step-by-step explanation:
Given the expression 4x-1 = 4x+7, we are to simplify the expression and find the value of x. To do that the following steps must be carried out.
Step 1: collect the like terms by regrouping the expression
4x-1 = 4x+7
4x - 4x = 7+1
0x = 8
Step 2: Dividing both sides by the number next to x
0x/0 = 8/0
x = ∞
Any constant dividing zero will always return infinity as a value.

a man earns $140 in a 5 day week. what is his pay in 3 days?
Answer:
$84
Step-by-step explanation:
divide 140 by the five days and you get 28 then you multiple it by the 3 days and you get $84
His pay for 3 days would be $84.
To find the man's pay for 3 days, we can use the concept of proportionality. Since the man earns $140 in a 5-day week, we can calculate his daily earnings by dividing the weekly earnings by the number of days in the week:
Daily earnings = Weekly earnings / Number of days in the week
Daily earnings = $140 / 5 days
Now, let's calculate the daily earnings:
Daily earnings = $140 / 5 days = $28 per day
Therefore, the man's pay for 3 days would be:
Pay for 3 days = Daily earnings * Number of days
Pay for 3 days = $28 * 3 days = $84
His pay for 3 days would be $84.
