Answer:

D: 21.23 sq in

Step-by-step explanation:

A tennis ball is a sphere, so we're going to use the surface area of a sphere formula. (4πr²)

Remember that radius is HALF of the diameter, which in this case is 2.6. This means the radius is 1.3.

π represents 3.14

Once you plug the values into the above equation, you should receive the above answer.

Classify each pair of numbered angles. Drag and drop the descriptions into the boxes to correctly classify each pair of numbered

Leona [35]

(i) Pairs of neighboring angles are supplementary and opposite angles have the same measure.

(ii) The two angles formed by a line coming out of another line are supplementary.

<h3>How to analyze pairs of angles</h3>

(i) When two straight lines pass through each other, then two pairs of opposite angles are constructed. A pair with angles of $(3\cdot x + 52)^{\circ}$ and another pair with angles of $(2\cdot x + 2)^{\circ}$ , each pair of angles with different measures are supplementary. $\blacksquare$

(ii) When a straight line comes out of another straight line, from a point distinct to any endpoint of the former, then we construct two supplementary angles. The largest angle has a value of $(10\cdot x + 20)^{\circ}$ , whereas the smaller one has a value of $(6\cdot x + 8)^{\circ}$ . $\blacksquare$

You are having a discussion about sequences with your classmate. She insists that the sequence 2, 3, 5, 8, 12 must be either ari

Marizza181 [45]

If arithmetic, then there is a common difference
if geometric, then there is a common ratio

to find the common ratio or difference

if you subtract successive terms from each other, they should have the same result if it is aritmetic
if you divide successive terms by each other, they should have the same result if it is geometric

2,3 and 5

3-2=1
5-3=2
2≠1
not aritmetic

3/2=1.5
5/3=1.66666
1.5≠1.6666
not geometric

she is wrong

Explain how you can use division to simplify a complex fraction.

PolarNik [594]

Reduce the final answer if needed (or reduce when you multiply). A mixed number should be converted to an improper fraction (heavier on top) before simplifying. Change the numerator and denominator to single fractions by creating a common denominator
