Answer:
Expression: 
Step-by-step explanation:
We are asked to write an expression and evaluate the expression.
4-thirds would be 
.
The sum of 4-thirds and 2 more would be 
.
8 copies of 4-thirds and 2 more would be 8 times .
Let us solve the expression.
Therefore, the solution for our given equation would be .
Answer:
R(x) = 2.25x + 4.49
Step-by-step explanation:
Equation form: R(x) = mx + b
m: represents the additional amount Joshua is charged for every day until he returns the movie, which in this case is $2.25. So, the value of m is 2.25.
b: represents the initial cost of renting the movie. Joshua rented the movie for $4.49, so b is 4.49.
Since we know the value of m and b, we can write the equation:
R(x) = 2.25x + 4.49
Answer:
46.84
Step-by-step explanation:
Add the decimals first to get .84 then add the real numbers to get 46.
Step-by-step explanation:
it it can be calculated by using the quadratic formula.
X=-b+_(√b^2-4ac)/2a
The option C) 49 inches is the circumference of the circular mat.
<u>Step-by-step explanation:</u>
- Tricia made a circular mat from a square piece of cloth.
- The measure of the side length of the square = 14 inches.
- The length of the side is same as the diameter of the circle.
- Therefore, the diameter of the circular mat = 14 inches.
<u>To find radius :</u>
Radius = diameter / 2
⇒ 14/2
⇒ 7 inches.
<u>To find the circumference of the circular mat :</u>
Circumference = 2πr
where,
π has the default value of 3.14
r is the radius of the circular mat.
⇒ 2 × 3.14 × 7
⇒ 44 inches.
∴ The circumference of the circular mat is 44 inches.
Since, it is not given in the option. The option C) 49 inches which is close to 44 inches is the right option.
