b. QP
C. PQ
d. PQ

Answers

Answer 1
Answer:

We have that

All the options above are correct but PQ is mostly used because of its places in the alphabetical system

Correct option is

a,c,d

From the question we are given that:

P Q as a length

Mostly used in Trigonometry and Geometry are letters for the representation of points and combined to form lengths and determine distances

Therefore P and Q as points are represented as lengths wen the are given as

Represented as PQ or QP (\bar {PQ})(\bar {QP})

In conclusion

All the options above are correct but PQ is mostly used because of its places in the alphabetical system

Correct option is

a,c,d

Which equation represents a circle with a center at (2, –8) and a radius of 11?

Answers

(x-h)^2 +(y-k)^2 = r^2 is the equation for a circle centered at (h,k) and radius r

(x-2)^2 +(y- (-8))^2 = 11^2

(x-2)^2 +(y+8)^2 = 11^2

Answer:(x-2)^2 +(y+8)^2 = 11^2

Answer:

(x-2)^2 + (y+8)^2 = 11^2

Step-by-step explanation:

The standard equation of a circle with center at (h,k) and radius r is

(x-h)^2 + (y-k)^2 = r^2.

Filling in the given info, we get:  

(x-2)^2 + (y+8)^2 = 11^2

35

Step-by-step explanation:

Answer:

The answer is 35

Step-by-step explanation:

When we divide two fractions, such as 1/7 ÷ 1/5, we flip the second fraction and then we simply multiply the numerators with each other and the denominator with each other.

We also simplify the answers to fraction problems whenever possible.

Olivia ordered 5 books online. Each book weighed 2 1/3 pounds. What is the total weight of Olivia's books if all the books are shipped to Olivia together?

Answers

Olivia ordered 11 2/3 pounds of books.

How to solve:
*Turn 2 1/3 into an improper fraction by doing denominator x whole number + numerator, so 3 x 2 + 1 which is 7/3.
* Multiply both fractions by doing numerator x numerator and denominator x denominator.
*This gives you 35/3 and now you just simplify by seeing how much times 3 can go into 35 so it is 11 times and 2 left over, so it is 11 2/3
2 1/3 = 7/3
5 × 7/3 = 35/3
35/3 = 11 2/3 pounds

Isabella spent $49 for 7 bracelets. Each bracelet cost the same amount. How much did each bracelet cost?

Answers

To answer this question, we first have to set up an equation with variables.
We can use "x" to represent the cost of each bracelet.

Equation: number of bracelets bought × cost of each bracelet = total cost

Number of bracelets bought: 7
Total Cost: 49

Using this information, we can fill in the equation and solve for x.

7x = 49

To isolate x, divide both sides by 7.

x = 7

Since x equals 7, we now know that each bracelet cost $7.

55% of what number is 77?

Answers

Set up an equation
Let the number be x.
55% of x = 77
"of" means multiply, so
55% * x = 77
55% is the same as 0.55 (% means divide by 100).
0.55x = 77
x = 140
