9514 1404 393

Answer:

  (c)  615.44 cm^2

Step-by-step explanation:

The surface area of a sphere is given by ...

  A = 4πr² . . . . where r is the radius, half the diameter

  A = 4(3.14)(7 cm)² = 196(3.14) cm² = 615.44 cm²

Use the figure to find the measures of the numbered angles,
Galina-37 [17]

Given:

A figure in which a transversal line t intersect the two parallel lines a and b.

To find:

The measure of the numbered angles.

Solution:

If a transversal line intersect the two parallel lines, then

1. Corresponding angles are equal.

2. Alternate interior angles are equal.

3. Alternate exterior angles are equal.

Now,

m\angle 1+99^\circ=180^\circ              (Linear pair)

m\angle 1=180^\circ-99^\circ

m\angle 1=81^\circ

m\angle 2=99^\circ                         (Vertically opposite angles)

m\angle 3=\angle 1=81^\circ                (Vertically opposite angles)

m\angle 4=99^\circ                         (Corresponding angles)

m\angle 5=\angle 3=81^\circ                (Alternate interior angles)

m\angle 6=99^\circ                         (Alternate exterior angles)

m\angle 7=\angle 3=81^\circ                (Corresponding angles)

Therefore, \angle 1=81^\circ, \angle 2=99^\circ,\angle 3=81^\circ, \angle 4=99^\circ,\angle 5=81^\circ, \angle 6=99^\circ,\angle 7=81^\circ.

What is the mode of the following numbers? 1,2, 10, 6, 4, 4, 6, 3, 1, 4​
marysya [2.9K]

Answer:

The mode of the data set is 4.

Step-by-step explanation:

Hey there!
The <u>mode</u> of a data set is the most commonly occurring data value in that set.

To begin, we need to organize the data set in <u>increasing order</u>:

1, 1, 2, 3, 4, 4, 4, 6, 6, 10

Then, we can tally the <u>frequency</u> of each data value occurring in the data set:

1 - II

2 - I

3 - I

4 - III

6 - II

10 - I

We can see that there are three occurrences for the data value 4 — which is the most frequent occurrence — so 4 is our answer.

Slav-nsk [51]

Answer:

T + V = 50

2T + (3/2) * V = 90

2T + 1.5V = 90

T = 50 * 1.5 - 90 * 1 / 1 * 1.5 - 2*1 = 30

V = 1 * 90 - 2 * 50 / 1 * 1.5 - 2 * 1 = 20

Step-by-step explanation:

T = 30

V = 20
