Answer

3. 14

4. 4

5. 8

Step-by-step explanation:

Answer:3) a=14      4( x=4        5) a=8

Step-by-step explanation:

3)QUESTION: 4+a=18

first you -4 from both sides to get rid of the 4 to put a on its own so now it is

a=14

ANSWER: a=14

4)QUESTION: 7x=28

you divide 7 by both sides to make 7 x to x

x=4

ANSWER: x=4

5) QUESTION:a+5=13

you minus 5 from both sides to put a on its own.

a=8

ANSWER= a=8

Answer:

B -1/2

Step-by-step explanation:

The given trigonometric expression can be evaluated as -1/2.

The trigonometric ratios are defined for a right angled triangle.

The example of these ratios are sin, cos, tan, cosec, sec and cot.

The trigonometric ratios are useful in determining the heights and distances of the large objects.

The given trigonometric expression is as below,

cos(11π/21)cos(π/7) - sin(11π/21)sin(π/7)

Suppose, A = 11π/7 and B = π/7

Then, the given expression can be written as,

cosAcosB - sinAsinB

As per the trigonometric identity cos(A + B) = cosAcosB - sinAsinB.

Then, the given expression can be written as,

⇒ cos(11π/21)cos(π/7) - sin(11π/21)sin(π/7) = cos(11π/21 + π/7)

⇒ cos(2π/3) = -1/2

Hence, the exact value of the given expression is -1/2.

Answer:

The expected value of the ticket is -$1.10

Step-by-step explanation:

Here, we want to find the expected value of the ticket sales

We start by calculating the probabilities

The probability that someone wins the system is 1/2000

The probability that a person loses the system is 1999/2000

So the expected value will be;

(1/2000 * 1,800) - (1999/2000 * 2)

= 0.9-1.999 = -1.099

To the nearest cent, this is -1.10

Answer:

v = 2/5    Or    v = 0.4

Step-by-step explanation:

12/5 = 6v

to isolate V divide both sides by 6

(12/5) : (6)= 6v : (6)

For the left side because there is a fraction when you devide you change it into multiplication, flipping the addent and quotient so you’ll have

12/5 * 1/6  (you semplify the cross numbers) you’ll have 2/5

on the right side the 6 cancel each other. Because 6/6 = 1. so you will have 1v which is v.

2/5 = v

or decimal form

0.4 = V

Case 1 :

Radius, r = 5 feet.

Area,

[tex]A=\pi r^2\\\\A = 3.14\times 5^2\ feet^2\\\\A = 78.5\ feet^2[/tex]

Case 2 :

Diameter, d = 56 mm.

So, radius, r = d/2 = 28 mm.

Area,

[tex]A = 3.14\times 28^2\ mm^2\\\\A = 2461.76\ mm^2[/tex]

Hence, this is the required solution.

Step-by-step explanation:

Step one:

given data

we are told that the team traveled 148miles south.

and also they traveled 132miles north.

Step two:

We are expected to solve for the total distance the team traveled

Hence total distance= 148+132= 280 miles in all

Note: the team;'s displacement is 148-138= 10miles in

If fighting is sure to result in victory, then you must fight!

Sun Tzu said that, and I'd say he knows a little more about fighting than you do, pal, because he invented it, and then he perfected it so that no living man could best him in the ring of honor.

Then, he used his fight money to buy two of every animal on earth, and then he herded them onto a boat and then he beat the cra p out of every single one.

And from that day forward any time a bunch of animals are together in one place it's called a 'zoo'!

Answer:

12.4cm (rounded to nearest tenth)

Step-by-step explanation:

To find the length of an arc, you have to find the circumference of the full circle itself multiplied by the angle of the arc over 360°. The circumference of a circle is pi × r × 2.

Length of arc = [tex]\frac{90}{360}[/tex] × 3.14 × 7.9 × 2

                      = 12.403

                      ≈ 12.4cm (rounded to nearest tenth)

Answer:

0.0021 in scientific notation is [tex]\mathbf{2.1 x 10 ^ {-3}}[/tex]

Step-by-step explanation:

We need to write 0.0021 in scientific notation.

Scientific Notation: A number expressed in scientific notation is written when numbers between 1 to 10 are multiplied by a power of 10.

In the given example 0.0021 our decimal will be shifted to the right 3 digits and the power will be negative 3 (-3)

So, 0.0021 in scientific notation is [tex]\mathbf{2.1 x 10 ^ {-3}}[/tex]
