[tex]\sf 343\dfrac{3}{4} \ mi[/tex]
1 inch = 125 miles
[tex]\rightarrow \sf 2\dfrac{3}{4} \ * \ 125[/tex]
[tex]\rightarrow \sf \dfrac{11}{4} \ * \ 125[/tex]
[tex]\rightarrow \sf \dfrac{1375}{4}[/tex]
[tex]\rightarrow \sf 343\dfrac{3}{4} \ mi[/tex]
Answer:
Option A
Step-by-step explanation:
Given:
1 inch = 125 milesTo avoid confusion, let's convert 2 3/4 into decimals. To convert a fraction into decimals, multiply and divide the fraction by 100.
⇒ (2 3/4 x 100)/100 = (11/4 x 100)/100 = (1100/4)/100 = 275/100 = 2.75
Now, multiply 2.75 to both sides of the equation "1 inch = 125 miles", as we need to find the actual distance of 2.75 inches
⇒ 1 inch = 125 miles
⇒ 1 × 2.75 = 125 × 2.75
⇒ 2.75 inches = 343.75 miles
The options given are in fraction form. So, we need to reconvert 343.75 into fraction form. Once again, multiply and divide the decimal by 100.
⇒ (343.75 × 100)/100 = (34375)/100
We can clearly tell that this is a mixed fraction because 34375 is greater than 100. To convert this fraction into mixed fraction, let's write the expanded form of this fraction.
⇒ (34375)/100 = 34000/100 + 300/100 + 75/100
⇒ (343 x 100)/100 + 75/100
⇒ 343 + 75/100 = 343 + 3/4
⇒ 343 3/4 miles (Option A)

Which of the following is a situation in which an equation CANNOT be solved using the quadratic formula ?
Answer:
C. One term has degree 3
Step-by-step explanation:
The quadratic formula is used to find the zeros of degree 2 polynomials. The coefficient of the linear term does not matter, and the coefficient of the x² term may be anything except 0.
If the degree of the polynomial is 3, the quadratic formula does not apply.
The national average utility cost is $270.48 per month. if the average electric bill is 44.9% of the total amount and the average utility cost for orlando, fl is $308.83, what would be the cost of a typical orlando electric bill and how would that compare with the national average? a. the typical orlando electric bill would be $138.66, which would be $17.21 more than the national average. b. the typical orlando electric bill would be $121.54, which would be $17.21 less than the national average. c. the typical orlando electric bill would be $138.66, which would be $76.64 more than the national average. d. the typical orlando electric bill would be $121.54, which would be $76.64 less than the national average.
The typical Orlando electric bill would be $138.66, which would be $17.21 more than the national average option (a) is correct.
It is given that the national average utility cost is $270.48 per month. if the average electric bill is 44.9% of the total amount and the average utility cost for Orlando, fl is $308.83.
It is required to find the cost of a typical Orlando electric bill and how would that compare with the national average.
What is average?It is defined as the single number that represents the mean value for the given set of data or the closed value for each entry given in the set of data.
We have:
Average utility cost = $270.48
Average electric bill = 44.9%
Average utility cost without electric bill = [tex]270.48\times \frac{44.9}{100}[/tex]
= $121.44
Typical orlando electric bill = [tex]308.83\times \frac{44.9}{100}[/tex]
= $138.66
Now,
=$138.66 - $121.44
= $17.22
Thus, the typical Orlando electric bill would be $138.66, which would be $17.21 more than the national average option (a) is correct.

The second term of an arithmetic sequence is –39. The rule a, - a-1 +12 can be used to find the next term of the
sequence. What is the explicit rule for the arithmetic sequence?
Answer:
a 2 = -39
a 2 = a 1 + 12
- 39 = a 1 + 12
a 1 = - 39 - 12
a 1 = - 51 ( first term )
The common difference is : d = 12

Nance still needs to ride 1 and 9/10 miles to reach her friend's house.
What is speed?Speed is a measure of how quickly an object moves from one place to another. It is defined as the distance traveled by an object per unit of time, and is often represented by the symbol "v". The formula for speed is:
Speed = Distance/Time
Nance is riding her bike to a friend's house that is 4 and 1/2 miles away. She has already ridden 2 and 3/5 miles. To find out how much farther she needs to ride, we can subtract the distance she has already ridden from the total distance:
Total distance = 4 and 1/2 miles
Distance already ridden = 2 and 3/5 miles
Total distance - Distance already ridden
4 and 1/2 - 2 and 3/5 = 9/2 - 13/5 (we need to get a common denominator)
= (45/10) - (26/10)
= 19/10
Therefore, Nance still needs to ride 1 and 9/10 miles to reach her friend's house.

What is an equation?An equation is a mathematical statement that shows that two mathematical expressions are equal.
For example, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.
An equation is a mathematical statement with an 'equal to' symbol between two expressions that have equal values.
For example, 3x + 5 = 15.
Given that, nine more than three times a number is -6, we need to find the number,
Let us consider the asked number be x
Establishing the equation, we get;
3x+9 = -6
Subtract 9 from both sides.
3x+9-9 = -6-9
3x = -15

In the given figure ABC is a triangle in which angle BAC is equal to 30 degree show that BC = the radius of the circumcircle of triangle ABC whose Centre is O.
Step-by-step explanation:
First, Join OB and OC.
∠BOC = 2∠BAC
(∵ angle subtended by an arc at the centre = double the angle subtended by it at any point on the remaining part of the circle)
=> ∠BOC = 2 x 30°...(∵ ∠BAC = 30°, Given)
=> ∠BOC = 60°
In, ΔOBC, OB = OC...(radii of same circle)
∴ ∠OCB = ∠OBC...(∠s opp. equal sides of a triangle are equal)
As the sum of angles of a traingle is 180°,
∠OBC + ∠OCB + ∠BOC = 180°
∠OBC + ∠OBC + 60° = 180°...(∵∠BOC = 60°,proved above)
2∠OBC = 120° => ∠OBC = 60°
Thus, we have ΔABC such that,
∠BOC = ∠OBC = ∠OCB = 60°
ΔOBC is an equilateral triangle
BC = OB i.e. BC is equal to the radius of circle.
