Answer:

Step-by-step explanation:

By tracing the figure, we see that we go around a semicricle twice and go in a straight path twice. So the perimeter of this figure consists of two semicircles and two line segments, hence the answer is C.

For this item, a non-integer answer should be entered as a fraction using / as the fraction bar.

Kipish [7]

The numerical expression, 2/3 ÷ 2⁴ + (3/4 + 1/6) ÷ 1/3 = <u>67/24</u> on simplification using the BODMAS rule.

In the question, we are asked to simplify the numerical expression:

2/3 ÷ 2⁴ + (3/4 + 1/6) ÷ 1/3.

To simplify the expression, we will follow the BODMAS rule, where B means Brackets, O means Of, D means Divide, M means Multiplication, A means Addition, and S means Subtraction.

2/3 ÷ 2⁴ + (3/4 + 1/6) ÷ 1/3

= 2/3 ÷ 16 + (3/4 + 1/6) ÷ 1/3 {Solving 2⁴ = 16, before proceeding BODMAS}.

= 2/3 ÷ 16 + ((9+2)/12) ÷ 1/3 {Solving Brackets by taking LCM}

= 2/3 ÷ 16 + 11/12 ÷ 1/3 {Simplifying}

= 2/3 * 1/16 + 11/12 * 3/1 {Solving divisions by taking reciprocals}

= 1/24 + 11/4 {Multiplying}

= (1 + 66)/24 {Adding using LCM}

= 67/24 {Simplifying}.

Thus, the numerical expression, 2/3 ÷ 2⁴ + (3/4 + 1/6) ÷ 1/3 = <u>67/24</u> on simplification using the BODMAS rule.

Find all solutions of the equation sin^2 x=2sinx+3

Mashutka [201]

$\sin^2x=2\sin x+3$
$\sin^2x-2\sin x-3=0$
$(\sin x-3)(\sin x+1)=0$

which means either $\sin x=3$ or $\sin x=-1$ . The equation has no solution, since $\sin x$ is always bounded between -1 and 1. The second has one solution at $x=-\dfrac\pi2$ , and any number of complete revolutions will also satisfy this equation, so in general the solution would be $-\dfrac\pi2+2k\pi$ where $k$ is any integer.

So you could choose $A=-\dfrac\pi2$ and $B=2$ .

A circular jogging track forms the edge of a circular lake that has a diameter of 2 miles. Johanna walked once around the track

Tpy6a [65]

Answer:

Option C is the answer.

Step-by-step explanation:

Given diameter is = 2 miles

So, radius will be = 1 mile

Let t represents the number of hours it took Johanna to walk completely around the lake.

Now, the circumference is given as: $2\pi r$

So, circumference = $2(3.14)(1)$ = 6.28 miles

Johanna's speed = 3 miles/ hour

We know the formula $Time=Distance / Speed$

t = $6.28/3$

t = 2.09 hours

This is greater than 2, but less than 2.5, therefore, 2.0 < t < 2.5 is the answer.

Solve: 2 ( x-2 ) = 6

Umnica [9.8K]

<span>2 ( x-2 ) = 6
Use distributive property.
2x - 4 = 6
Add 4 to both sides
2x = 10
Divide 2 on both sides so that the only thing remaining on the left side is the variable x.
Final Answer: x = 5</span>
