Answer:

$\Delta s = 1$

Step-by-step explanation:

The length of the arc is directly proportional to the angle of the arc, whose measure is determined by simple rule of three:

$\Delta s = \left(\frac{60^{\circ}}{360^{\circ}} \right)\cdot (6)$

$\Delta s = 1$

complete question:

A circle with circumference of 6, has an arc with a ∘ 60, degree central angle.

Answer:

length of an arc = 1

Step-by-step explanation:

The length of an arc is defined with the following formula.

length of an arc = ∅/360 × 2πr

circumference of a circle = 2πr

circumference = 6

length of an arc = ∅/360 × 2πr

length of an arc = ∅/360 × 6

where

∅ = 60°

length of an arc = 60/360 × 6

length of an arc = 360/360

length of an arc = 1

What is the third side

ASHA 777 [7]

Answer:

A. 2.82 m

Step-by-step explanation:

The missing side we are trying to find is the hypotenuse, this is because it is the longest side of a right triangle.

The Pythagorean Theorem is used:

$a^2+b^2=c^2$

Plug in the given numbers (2), accordingly:

$2^2+2^2=c^2\\4+4=c^2\\8 = c^2\\$

Take the square root of both sides:

$\sqrt{8} =\sqrt{c^2}$

2.82 ≈ c

Four batsmen on a cricket team had a mean of 42.5 runs the other 7 batsmen had a mea of 18 what was the mean number of scored by

Ira Lisetskai [31]

Answer:

The mean score of the entire team is 26.909.

Step-by-step explanation:

Given that four batsmen had a mean of 42.5.

Let $\textbf{B}_{\textbf{i}$ , where $i = 1, 2, 3, \hdots, 11$ denote the batsmen.

From the first statement, we have:

$\frac{B_1 + B_2 + B_3 + B_4}{4} = 42.5$

$\implies B_1 + B_2 + B_3 + B_4 = 42.5 \times 4 = \textbf{170}$

Therefore, the sum of the scores of the first four batsmen is 170.

Now, from the second statement we have:

$\frac{B_5 + B_6 + B_7 + B_8 + B_9 + B_{10} + B_{11}}{7} = 18$

$\implies B_5 + B_6 + B_7 + B_8 + B_9 + B_{10} + B_{11} = 18 \times 7 = \textbf{126}$

That is, the sum of the scores of the remaining 7 batsmen is 126.

Now, to calculate the average(mean) of the entire team, we add the individual scores and divide it by 11.

$\implies \frac{B_1 + B_2 + B_3 + B_4 + B_5 + B_6 + B_7 + B_8 + B_9 + B_{10} + B_{11}}{11} = \frac{170 + 126}{11}$

$= \frac{296}{11}$

$= \textbf{26.90}$ which is the required answer.
