What Is The Best Approximation Of The Length Of The Radius In A Circle With An Area Of 167 M2?a. 4.6

Answers

Answer 1

Answer:

r = 7.3 m

Step-by-step explanation:

A = (pi)(radius)^2, so, if A = 167 m^2, r^2 is found as follows:

       

         167 m^2

r^2 = -------------- = 53.158 m^2

              3.14

Taking the square root of both sides, we get

r = 7.3 m

This is correct, because A = (pi)(radius)^2 becomes (3.14)(7.3 m)^2 = 167.4 m^2

HELP HELP HELP A triangle has two sides of length 14 and 18. What is the largest possible whole-number length for the third side?

Answers

The way you can do this is Pythagorean theorem. Since the hypotenuse has to be the highest part. So you would do 14^2 + 18^ = c^2 and then do that and you get 196 + 324 which is equal to 520 so then get the square root of that which is 22.8, but it says largest possible whole number length so you would put 22.

Frozen chickens will be sold by a major chain of supermarkets only if their weight
is at least 1.2 kg and not more than 3.4
kg.
(a) Represent this information on a number line.
Write an inequality to describe this.​

Answers

Answer:

In the number line it should be between 1.2 and 3.4

intervals of 0.2

for e.g: 3.4 3.2 3.0 2.8 2.6 2.4 2.2 2.0 1.8 1.6 1.4 1.2  

Step-by-step explanation:

Assume chicken to be x

1.2 [tex]\leq[/tex] x < 3.4

Inequality shows a relationship between two numbers or two expressions.

The inequality to describe the chicken that can be sold only when the chicken weighs between 1.2 kg to 3.4 kg is

1.2 ≤ x ≤ 3.4

Where x is the number of chicken.

What is inequality?

It shows a relationship between two numbers or two expressions.

There are commonly used four inequalities:

Less than = <

Greater than = >

Less than and equal = ≤

Greater than and equal = ≥

Example:

2 < 3

3x > 2x

3x + 4 > 4x

We have,

Number of chickens that can be sold = x

Chicken is sold only if the chicken weighs between 1.2 kg and 3.4 kg.

This can be represented by inequality as,

1.2 ≤ x ≤ 3.4

Thus,

The inequality to describe the chicken that can be sold only when the chicken weighs between 1.2 kg to 3.4 kg is

1.2 ≤ x ≤ 3.4

What is Probability?

It is a branch of mathematics that deals with the occurrence of a random event.

Given that $14,000 is deposited into a savings account with an annual interest rate of 4% compounded continuously.

We need to find the amount in the account after 3 years.

[tex]A=Pe^r^t[/tex]

where A is the amount of money after t years,

P is the principal amount

r is the annual interest rate

P = $14,000, r = 0.04 and t=3

[tex]A = 14000e^(^0^.^0^4^3)[/tex]

A = 15,784

Hence, $14,000 is deposited into a savings account with an annual interest rate of 4% compounded continuously then $15,784 is the amount after 3 years.

1. -3 x - 5 = 16

2. -4(y-2) = 12

(don’t put links. Or i’ll report you)

Answers

Answer:

1. x= -7

2. y= -3.5

Step-by-step explanation:

1. x = -7
2. y = -1

For number 1:

Plus five both side of the equation and you get -3x = 21

Divide -3 both side and you get x = -7

For number 2:

Multiply -4 by y and -2 .... you get -4y + 8 = 12

Minus 8 side of the equation and you get -4y = 4

Divide by -4 both sides and you get y = -1

Question 10:
Find the cosine of angle J.

Answers

Answer:

1/14

Step-by-step explanation:

According to SOH CAH TOA;

Cos theta = adjacent/hypotenuse

Since theta = <J

Adjacent = 2

Hypotenuse = 28

Cos <J = adj/hyp

Cos<J = 2/28

Cos<J = 1/14

Hence the value of cosine J is 1/14
