A first number is nine less than a second. The sum of the numbers is 45. Find the numbers.

oee [108]

Answer:

The first number is 18 and the second number is 27.

Step-by-step explanation:

Given:

A first number is nine less than a second.

The sum of the numbers is 45.

Now, to find the numbers.

Let the second number be $x.$

And the first number be $x-9.$

The sum of the both numbers is 45.

According to question:

$(x-9)+x=45.$

⇒ $x-9+x=45.$

⇒ $2x-9=45.$

Adding both sides by 9 we get:

⇒ $2x=54.$

Dividing both sides by 2 we get:

⇒ $x=27.$

The second number = 27.

Now, to get the first number we put the value of $x$ :

$x-9$

$=27-9$

$=18.$

Therefore, the first number is 18 and the second number is 27.

1) Find the circumference and area of each circle:

MA_775_DIABLO [31]

Answer:

a] Radius of circle = 10 feet

Circumference of circle = 94.2 feet (Approx.)

Area of circle = 314 feet² (Approx.)

b] Radius of circle = 6 cm

Circumference of circle = 37.68 cm (Approx.)

Area of circle = 113.04 cm² (Approx.)

Step-by-step explanation:

Given:

a] Radius of circle = 10 feet

b] Radius of circle = 6 cm

Find:

Circumference an area for both circle

Computation:

Circumference of circle = 2πr

Area of circle = πr²

a] Radius of circle = 10 feet

Circumference of circle = 2(3.14)(10)

Circumference of circle = 94.2 feet (Approx.)

Area of circle = (3.14)(10)²

Area of circle = 314 feet² (Approx.)

b] Radius of circle = 6 cm

Circumference of circle = 2(3.14)(6)

Circumference of circle = 37.68 cm (Approx.)

Area of circle = (3.14)(6)²

Area of circle = 113.04 cm² (Approx.)

sertanlavr [38]

Answer:

66.6667

2 out of 66.6667 is 3%

Step-by-step explanation:

2 out of what is 3%?

2 out of X is 3%

Equation: Y/X = P%

Solving our equation for X

X = Y/P%

X = 2/3%

Converting percent to decimal:

p = 3%/100 = 0.03

X = 2/0.03

X = 66.6667
