Step-by-step explanation:
The range is the difference between the largest and smallest values.
range = 9 - 2 = 7
If 2 is replaced by 3 then 3 becomes the smallest value and
range = 9 - 3 = 6
That is the range decreases by 1

Box A contains 10 pens that are either red or blue in colour. Box B contains 23 pens that are also either red or blue in colour. The number of blue pens in Box B is twice the number of blue pens in Box A while the number of red pens in Box B is thrice the number of red pens in Box A. Write a pair of linear equations using b as the number of blue pens in Box A and r as the number of red pens in Box A.
Answers
Answer:
b + r = 10 - - (1)
2r + 3b = 23 - - (2)
Step-by-step explanation:
Number of Blue pens in box A = b
Number of red pens in box A = r
BOX A :
Contains 10 pens that are either red or blue
b + r = 10
BOX B:
Contains 23 pens that are either red or blue ;
Red pens in box B = 2 tines the number of red pens in box A
Blue pens in box B = 3 times the number of blue pens in box A

a rectangular canvas covers 225 square inches on a wall. If the canvas has a height of 18 inches then what is the base?
Answers
Answer:
12.5 Sq inches
Step-by-step explanation: 225 is the area and the formula for area is b*h (base times height) and from the problem, you can see that 18 inches is the height. In this case you would do 225/18 which gives you 12.5 sq inches.

Choices- 333.50, 63.50, 153.50, 166.75
Answers
180-13.25-13.25 = 153.50
The two acute angles are the same so look for the obtuse.
Answer:
153.50
Step-by-step explanation:
Sum of all interior angles of a triangle is 180°.
Option(1): 333.5 is much greater than 180(sum of all angles). 333.5 + 13.25 + angle P = 180, for all +ve values of angle P.
/_P = 180° - 13.25 - 333.5 , /_P is -ve from this which is impossible(for an angle in triangle)
This is incorrect.
Option(2): As it can observed, /_ R is much greater than 90°. It means, it should be greater than 63.50°.
This is incorrect.
Option(3): 153.50 is greater than 90°. Moreover, if /_ R is 153.5, let /_P be x, then,
=> 13.25 + 153.50 + x = 180°
=> x = 13.25. , which is +ve
So we can say /_P = 153.50
Option(4): if /_ R is 153.5, let /_P be x, then,
=> 13.25 + 166.75 + x = 180°
=> x = 0 , which is impossible(as we can see It's not 0)
Incorrect.

A company rents out 15 food booths and 23 game booths at the county fair. The fee for a food booth is $125 plus $7 per day. The fee for a game booth is $65 plus $5 per day. The fair lasts for d days, and all the booths are rented for the entire time. Enter a simplified expression for the amount, in dollars, that the company is paid.
Answers
Answer:
3,370 + 220d
Step-by-step explanation:
Food booth = 15
Game booth = 23
The fair lasts for d days
Cost of a food booth = 125 + 7d
Total cost of food booth = 15(125 + 7d)
= 1875 + 105d
Cost of a game booth = 65 + 5d
Total cost of game booth = 23(65 + 5d)
= 1495 + 115d
Total amount paid to the company = Total cost of food booth + Total cost of game booth
= (1875 + 105d) + (1495 + 115d)
= 1875 + 105d + 1495 + 115d
= 3,370 + 220d
The area of a square is greater than the area of the circle by 12 cm^2. Find the length of the side of a square if the area of the circle is 36 cm^2?
Answers
Answer:
Adding 12 to the circle area is equal to the square area.
Or
s2 = 12 + A
Where
s = side of square
A = area of circle
So
s2 = 12 + 36
s2 = 48
Solve this for s to get the side length

The price of televisions has dropped dramatically over the last three years. Three years ago a 32 inch television was $500. This year the tv was on sale for $199. What is the percent change?
Answers
A percentage is a way to describe a part of a whole. The percentage change in the price of the TV will be 60.2%.
What are Percentages?A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
As it is mentioned that the price of the tv 3 years ago was $500, while the current price of the tv is $199. Therefore, the percentage change in the price of the tv can be written as,
[tex]\rm Percentage\ change = \dfrac{\text{Initial value - Final value}}{Initial\ value} \times 100\%[/tex]
[tex]\rm Percentage\ change = \dfrac{\$500-\$199}{\$500} \times 100= 60.2\%[/tex]
Hence, the percentage change in the price of the TV will be 60.2%.

can you begin solving x-2/x+3 ≥2 by multiplying both sides of the inequality by x+3? Explain your answer.
Answers
Answer:
yes, but there is a better way
Step-by-step explanation:
instead of multiplying x+3 on both sides, I would instead subtract 2 on both sides. If you do this, it would be easier to write this equation in standard form and find the intervals.
In summary, to solve the inequality (x - 2)/(x + 3) ≥ 2, we can multiply both sides of the inequality by x + 3 only when x > -3 to preserve the direction of the inequality.
To solve the inequality (x - 2)/(x + 3) ≥ 2, we need to consider the impact of multiplying both sides of the inequality by x + 3.
When multiplying both sides of an inequality by a positive number, the direction of the inequality remains the same. However, if we multiply both sides by a negative number, the direction of the inequality is reversed.
In this case, the expression x + 3 is in the denominator of the left side of the inequality. If we multiply both sides of the inequality by x + 3, we need to consider two scenarios:
If x + 3 is positive: In this case, we can multiply both sides of the inequality by x + 3 without changing the direction of the inequality.
If x + 3 is negative: Multiplying both sides of the inequality by x + 3 would require flipping the direction of the inequality.
Therefore, we need to ensure that x + 3 is positive before multiplying both sides by x + 3 to preserve the direction of the inequality.
To determine when x + 3 is positive, we set the denominator equal to zero and solve for x:
x + 3 = 0
x = -3
So, if x > -3, then x + 3 is positive.
In summary, to solve the inequality (x - 2)/(x + 3) ≥ 2, we can multiply both sides of the inequality by x + 3 only when x > -3 to preserve the direction of the inequality.

Find sin 0, where 0 is the angle shown.
Give an exact value, not a decimal approximation.
Answers
Answer:
Answer: Sin0 = 8/8.5
Step-by-step explanation:
Step-by-step explanation: What we have is a right angled triangle, with two sides given and one angle which is the reference angle (unknown angle).
The Sine of the angle is calculated as
Sin0 = opposite/hypotenuse
We have the opposite side (facing the reference angle) as 8 units and the hypotenuse (facing the right angle unknown), which we shall label as X.
To calculate the hypotenuse, we shall apply the Pythagoras theorem which is,
X² = 3² + 8²
X² = 9 + 64
X² = 73
Adding the square root sign to both sides of the equation, we now have
X = √73
X = 8.5 (approximately)
Now that we have the hypotenuse as 8.5, the Sine of the angle can now be calculated as
Sin0 = opposite/hypotenuse
Sin0 = 8/8.5
