Using π = 3.14, what is the circumference of a circle with a radius of 18 units? Round your answer to the nearest hundredth.

Answer:

2/3

Step-by-step explanation:

So find the change in x first....1 + 2 = 3....so, change in x is +2

Next find the change in y....-4 + 3 = -1....so, change in y is +3

Slope equals change in y/ change in x

So, the slope is 2/3

Hope this helps :D

Answer:

2/3

Step-by-step explanation:

To find the constant of proportionality in the set of data apply the formula for slope where;

m= Δy/Δx

Taking values such as {3,2} and {6,4} then

m= 4-2 / 6-3

m= 2/3

Given:

The expression is

[tex]12+36\div(6^2\div 3^2)[/tex]

To find:

The value of the expression.

Solution:

BODMAS: Brackets, orders, division, multiplication, addition and subtraction.

We have,

[tex]12+36\div(6^2\div 3^2)[/tex]

Using BODMAS, first solve the brackets.

[tex]=12+36\div(36\div 9)[/tex]

[tex]=12+36\div(4)[/tex]

Now, divide.

[tex]=12+9[/tex]

Now, add.

[tex]=21[/tex]

Therefore, the value of given expression is 21.

Answer:

The answer is C.

Step-by-step explanation:

I did the test and got it right. :)

The correct is C = Multiply the first equation by 2 and the second equation by 3.

The elimination method exists utilized to solve a system of linear equations. It is the most widely used and simple method as it concerns fewer calculations and steps. In this manner, we eliminate one of the two variables and test to solve equations with one variable.

if we'll multiply the first equation by 2 and second by 3 we will be able to solve the equation by elimination.

(-3x+2y=16) X 2 = -6x + 4y = 32

(2x+5y=21) X 3 = 6x + 15y = 63

the coeffients of x gets cancelled out on adding the new equations

4y+ 15y = 32+ 63

19y = 95

y= 95/19

Answer:

The car must drive at 108 km/h to cover the same journey.

Step-by-step explanation:

Given that:

Time taken by bus journey = 45 minutes = [tex]\frac{45}{60} = 0.75\ hour[/tex]

Speed of bus = 60 km/h

Distance of the journey = Speed * Time

Distance of the journey = 60 * 0.75 = 45 km

The car needs to cover 45 km in 25 minutes.

25 minutes = [tex]\frac{25}{60}\ hour[/tex]

Distance = Speed * Time

45 = [tex]\frac{25}{60}*Speed[/tex]

Speed = [tex]45*\frac{60}{25}[/tex]

Speed = 108 km/h

Hence,

The car must drive at 108 km/h to cover the same journey.

Answer:

The length of the chord is 16 cm

Step-by-step explanation:

Mathematically, a line from the center of the circle to a chord divides the chord into 2 equal portions

From the first part of the question, we can get the radius of the circle

The radius form the hypotenuse, the two-portions of the chord (12/2 = 6 cm) and the distance from the center to the chord forms the other side of the triangle

Thus, by Pythagoras’ theorem; the square of the hypotenuse equals the sum of the squares of the two other sides

Thus,

r^2 = 8^2 + 6^2

r^2= 64 + 36

r^2 = 100

r = 10 cm

Now, we want to get a chord length which is 6 cm away from the circle center

let the half-portion that forms the right triangle be c

Using Pythagoras’ theorem;

10^2 = 6^2 + c^2

c^2 = 100-36

c^2 = 64

c = 8

The full

length of the chord is 2 * 8 = 16 cm

Answer:

B.) 9 in.

Step-by-step explanation:

a^2 + b^2 = c^2

a^2 + 12^2 = 15^2

a^2 + 144 = 225

a^2 = 225 - 144

a^2 = 81

√a^2 = √81

a = 9

Step-by-step explanation:

65% of 1,200 is 780 :)

Answer:

780

Step-by-step explanation:

65% x 1,200 = 780

The system of equations that represents Candace's and Amar's combined money is c + a = 85.

A linear equation is an algebraic equation of degree one. In general, the variable or the variables(in the case of a linear equation in two variables) the variables are x and y.

Given, Candace has $15 more than Amar.

Assuming Amar has $a.

∴  Candace(c) has $(x + 15).

Their combined money totals $85.

So, the equation that represents their combined money is

x + (x + 15) = 85 or a + c = 85.
