What two numbers add to make 36 with one of the numbers being exactly twice the other? smaller number = and larger number =

Answers

Answer 1
Answer:

Answer:

Smaller number = 12

Larger number = 24

Step-by-step explanation:

Let's call X the smallest number, while Y is the largest number.

In this case, Y = 2X

The equation that represents the given case is,

X + Y = 36

But being Y = 2X we substitute in the equation, obtaining ...

X + 2X = 36

Now we add the X ...

3X = 36

We isolate the X to know its value ...

x=(36)/(3)

X = 12

Now we calculate the value of Y ...

Y = 2X

Y = 2 (12)

Y = 24

Smaller number = 12

Larger number = 24

Both conditions are met:

(1) The largest number is twice the smallest number: 12 * 2 = 24

(2) The sum of the two numbers is 36: 12 + 24 = 36

Hope this helps!
Answer 2
Answer: 12 and 24
The equation is 2x + x =36
So 3x = 36
Then divide each side by 3
So x =12
That is the smaller number
Multiply it by 2 to get the bigger number since it's twice the number

If you have a semi-circle with a diameter of 8.6ft, what's the semi-circles area? Use the formula \pi r^(2)

Answers

So,

The diameter is 8.6ft.  We need to convert to radius.

2 radius = 1 diameter

8.6/2 = 4.3 ft.

\pi r{2}

\pi 4.3^(2)

\pi 18.49

3.14(18.49)

58.0586ft.²

Divide by 2 (semi-circle)
29.0293ft.²

The perimeter of a rectangle is 30 cm. The width of the rectangle is 7 cmWhat is the area of the rectangle?

A) 56 cm

B) 49 cm

C) 14 cm

Answers

Let's say the length of the rectangle is L.

We have P= (L+W)*2
⇒ 30 cm= (L+ 7 cm)*2
⇒ L+ 7 cm= 15 cm
⇒ L= 8 cm.

S= L*W= 8 cm* 7 cm= 56 cm^2.

The answer is A) 56 cm^2.

Hope this helps~
perimeter = 2(l+w)
30 = 2(l+7)
30 = 2l + 14
30 - 14 = 2l
16 = 2l
8 = l

l = 8
w = 7

area = l x w = 8 x 7 = 56 cm²
