The amount of sales tax rate on the scented pencils will be equal to 7%.
What is the Percentage?The Latin phrase "per centum," which means "by the hundred," is where the English word "percentage" comes from. Percentage segments are those with a numerator of 100. In other words, it is a connection where the whole is always deemed to be valued 100.
As per the given information in the question,
Price of scented pencils = $7
Price of pencils after-tax = $7.49
Then, the percentage of tax on the pencils will be,
= (7.49 - 7)/7 × 100
= 0.07 × 100
= 7%

The area of a rectangle is 45 square inches. The rectangle is 9 inches long. How wide is the rectangle?
A. 5 inches
B. 36 inches
C. 27 inches
D. 3 inches
Final answer:
To find the width of a rectangle with an area of 45 square inches and a length of 9 inches, divide the area by the length, resulting in a width of 5 inches (Option A).
Explanation:
The area of a rectangle can be calculated by multiplying its length by its width. In this case, we know the area is 45 square inches and the length is 9 inches. To find the width, we divide the area by the length.
Width = Area ÷ Length = 45 sq in ÷ 9 in = 5 in
Therefore, the width of the rectangle is 5 inches, which corresponds to option A.
Keith's florists has 15 delivery trucks, used mainly to deliver flowers and flower arrangements in the greenville, south carolina, area. of these 15 trucks, 5 have brake problems. a sample of 4 trucks is randomly selected. what is the probability that 2 of those tested have defective brakes?
Answer:
Hence, the probability is:
0.296
Step-by-step explanation:
This can be solved with the help of the binomial probability as:
[tex]P(x=r)=n_C_rp^r(1-p)^{n-r}[/tex]
where n denote the quantity which are chosen.
r denote the quantity whose probability is to be determined or success.
and p denote the probability of success.
with n=4 since 4 trucks are randomly selected.
p=5/15=1/3 ( As 5 have brake problems out of total 15 trucks)
1-p=10/15=2/3
r=2 ( since we are asked to find the probability that 2 of those tested have defective brakes)
Hence, the probability is:
[tex]P(x=2)=4_C_2(\dfrac{1}{3})^2(\dfrac{2}{3})^2\\\\\\P(x=2)=\dfrac{4!}{2!\times (4-2)!}\times \dfrac{1}{9}\times \dfrac{4}{9}\\\\\\P(x=2)=0.296[/tex]
Hence, the probability is:
0.296
You can use a minus sign to make a negative number like -2. what happens if you put a plus sign before a number? what about 2++2?
Final answer:
A plus sign before a number does not change its value. In the expression 2++2, the two plus signs next to each other are interpreted as a positive number followed by another positive number.
Explanation:
When you put a plus sign before a number, it doesn't change the value of the number.
The plus sign is just a symbol to indicate that the number is positive.
In the expression 2++2, the two plus signs next to each other are not a valid mathematical operation.
Instead, it is interpreted as a positive number followed by another positive number.
So, 2++2 is equal to 2+2, which is 4.
A car travels 252 miles in 5 hours and 15 minutes. how many miles does it travel per hour?
Answer:
48 miles per hour
Step-by-step explanation:
5hrs and 15minutes = 315minutes
If 252 = 315
x = 60
By cross multiplication
315x = 60 * 252
315x = 15,120
x = 15120/315
x = 48 miles per hour
A video game arcade offers a yearly membership with reduced rates for game play. A single membership costs $60 per year. Game tokens can be purchased by members at the reduced rate of $1.00 per 10 tokens. Which statements represent the function of the yearly cost in dollars, y, based on x, the number of game tokens purchased for a member of the arcade? Check all that apply. The slope of the function is $1.00. The y-intercept of the function is $60. The function can be represented by the equation y = 1/10x + 60. The domain is all real numbers. The range is {y| y ≥ 60}.

Unit conversion is the conversion of one unit to another unit with its standard conversion.
The actual dimension of the recreation room is 24 feet x 21 feet.
What is unit conversion?It is the conversion of one unit to another unit with its standard conversion.
Example:
1 minute = 60 seconds
1 km = 1000 m
1m = 100 cm
1 hour - 60 minutes
We have,
Recreation room dimension on the blueprint:
= 2 inches x 1.75 inches ______(A)
Scale factor:
1 inch = 12 feet
The actual dimension of the recreational room:
1 inch = 12 feet
Multiply 2 on both sides.
2 inches = 24 feet _____(1)
1 inch = 12 feet
Multiply 1.75 on both sides.
1.75 inches = 1.75 x 12 feet
1.75 inches = 21 feet ______(2)
From (1) and (2) and (A) we get,
= 2 inches x 1.75 inches
= 24 feet x 21 feet
Thus,
The actual dimension of the recreation room is 24 feet x 21 feet.

Experimental value = 10 km
accepted value = 12 km
Step 1: Deduct the accepted value from the experimental value.
10 km – 12km = -2 km
Step 2: Take the absolute value of step 1
|--2km| = 2km
Step 3: Divide that answer by the accepted value. 2km/10km = 0.2%

Triangle A B C with angle A measuring thirty degrees, angle B measuring seventy degrees and angle C marked x
Answer: In a triangle, the sum of the 3 angles is always equal to 180°
Then if the angle A is equal to 30°, the angle B is equal to 70°, what is the angle C?
if x is the angle C, and using the first statement, we got:
30° + 70° + x = 180°
100° + x = 180°
x = 180° - 100° = 80°
So the angle of C is equal to 80°.

Mr. Guzman drove his car 1080 miles in 6 weeks.
If he drove the same distance every week, which equation shows how far he drove each week (d)?
A.
d = 6 ÷ 1080
B.
d = 1080 – 6
C.
d = 1080 • 6
D.
d = 1080 ÷ 6
Mr. Guzman drove 1080 miles in 6 weeks. To find the distance driven each week, use the equation d = 1080 ÷ 6, which equals 180 miles per week. Therefore, the correct equation is option D.
Mr. Guzman drove 1080 miles in 6 weeks. We need to find out how far he drove each week if he drove the same distance every week.
Identify the Total Distance Driven: 1080 milesIdentify the Total Time Period: 6 weeksSet Up the Equation: Since Mr. Guzman drove the same distance every week, we use the formula:
d = Total Distance / Total Time.Substitute Known Values:
d = 1080 ÷ 6Calculate the Result:
d = 180 miles per weekThe correct equation that shows how far Mr. Guzman drove each week is d = 1080 ÷ 6, which corresponds to option D.
