Explanation for statement 3 :
Suppose The number of shoppers on Saturday is 100 and the number of shoppers on Sunday is 200
Total number of shoppers = 300
On Saturday :
Q₃ = 70 then 25% of shoppers spent more then $70
then 25 shopper spent more then $70
On Sunday:
M’ = 70 then 50% of shoppers spent more then $70
then 100 shopper spent more then $70
On both days:
(100+ 25) shopper spent more then $70
Then 125 shopper spent more then $70
But 125 is not 75% of 100+200=300

solve the equation and find the value of the variable
Answers
Answer:
[tex]\boxed{\sf{b=4.5}}[/tex]Step-by-step explanation:
To find the value of variable, you have to isolate the term of b from one side of the equation.
b+1.5=6First, you subtract by 1.5 from both sides.
→ b+1.5-1.5=6-1.5
Solve.
Subtract the numbers from left to right.
⇒ 6-1.5=4.5
⇒ b=4.5
Therefore, the correct answer is b=4.5.I hope this helps you! Let me know if my answer is wrong or not.

The circle illustrates the theorems of angles in the same segment
The measure of angle NTS is 53°The measure of arc AB is 200°How to determine the measure of NTS?Given that:
∠SKA = 74°
The angle SKA is at the center of the circle.
This means that:
Arc AS = 74°
Calculate Arc SN using:
SN + AS = 180°
Substitute 74 for AS
SN + 74° = 180°
Subtract 74 from both sides
SN = 106°
The arc SN is subtended by the angle NTS.
This means that:
∠NTS = 0.5 * SN
So, we have:
∠NTS = 0.5 * 106°
Evaluate
∠NTS = 53°
Hence, the measure of angle NTS is 53°
How to determine the measure of arc AB?Given that:
∠BCA = (7w - 4)°
∠ADB = (5w + 20)°
Angles subtended by the same arc at the circumference are congruent.
So, we have:
7w - 4 = 5w + 20
Collect like terms
7w - 5w = 20 + 4
Evaluate
2w = 24
Divide by 2
w = 12
This implies that:
∠BCA = (7 * 12 - 4)°
Evaluate
∠BCA = 80°
The measure of arc AB is then calculated using:
AB = 360 - 2 * ∠BCA
This gives
AB = 360 - 2 * 80°
Evaluate
AB = 200°
Hence, the measure of arc AB is 200°

A student made two patterns to show multiplication of a decimal by powers of ten. The equations shown for both patterns are incorrect.
Pattern A
3.675. 10 = 3.6750
3.675. 100 = 3.67500
3.675 • 1,000 = 3.675000
Pattern B
3.675.0.1 = 3.0675
3.675.0.01 = 3.00675
3.675 . 0.001 = 3.000675
Answers
The correct solving of the decimal shows that 3.675 × 10 = 36.750, 3.675 × 100 = 367.5 and 3.675 × 1,000 = 3675.
How to solve the decimals?From the information given, it should be noted the students calculations are incorrect. Therefore, 3.675 ×10 = 3.6750, 3.675 × 100 = 3.67500 and 3.675 × 1,000 = 3.675000 are incorrect.
In this case, when multiply by raise to power 10, it's important to shift the decimal based on the number being raised to power.
Therefore, 3.675 × 10 = 36.750, 3.675 × 100 = 367.5 and 3.675 × 1,000 = 3675.

Answer:
15 represents where Jerry is after the elevation dropped 25 meters and then rose 40 meters.
Step-by-step explanation:
It's given that Jerry hiked downhill to a valley where the elevation dropped 25 meters below his starting position. Then, he hiked up to a hill that was 40 meters higher than the valley
Hiked downhill = 25 meters
Hiked up = 40 meters
The given equation is
Here, hiked downhill represented by negative sign and hiked up resents by positive sign.
So, 15 represents that Jerry hiked up 15 meters from his starting position.

A fruit company delivers its fruit in two types of boxes: large and small. Delivery of 8 large boxes and 4 small boxes has a total weight of 173 kilograms. Delivery of 3 large boxes and 2 small boxes has a total weight of 68 kilograms. How much does each type of box weigh?
Weight of each large Box: ?
Weight of each Small Box: ?
Answers
Answer:
x = 18.5 (large) , y = 6.25 (small)
Step-by-step explanation:
Let's start by assigning variables to each type of box.
The large box we will call "x"
The small box we will call "y"
We know that 8x + 4y = 173 (kilograms)
And 3x + 2y = 68 (kilograms)
Since we set up a system of equations, we can now use elimination, by multiplying the entire bottom equation by -2, to get rid of the "y" variable.
8x + 4y = 173
3x(-2) + 2y(-2) = 68(-2)
-6x + -4y = -136 (side note: notice how the "y"'s would cancel each other out because -4y + 4y equals 0)
Add equations together:
2x = 37
x= 18.5
Now that we have x, just substitute it into any of the equations to get y.
You will see that y = 6.25

Answers
The question refers to the speed of sound waves. The expression that shows the waves from the fastest to the slowest is option A. See attached for full question
What are sound waves?A sound wave is the rhythm of disruption induced by the flow of energy as it propagates away from the source of the sound across a medium.
Why is option A the correct answer?Option A - is the correct answer because the temperature of a medium ( which may be air, water, or solid matter) affects the speed at which waves of sound travel through it.
The faster sound waves flow through a medium, the higher its temperature. This is why Wave X will pass through the fastest at 33°C, followed by Wave W at 15°C, etc.
