Answer:

4/10 : 1/25

4/10 / 1/25 = 4/10 x 25/1 = 100/10 = 10.

10 can also be written as 10:1, so A is correct.

Hope this helps!

the units digit of a two-digit number is twice the tens digit. If the digits are reversed, the new number is 9 less than the ori
Anton [14]

Answer:

36

Step-by-step explanation:

Here is the correct and complete question: The units digit of a two-digit number is twice the tens digit. If the digits are reversed, the new number is 9 less than twice the original number. What is the original number?

Lets assume the original number be"10y+x". (x is unit digit and y is 10th digit)

∴ if number is reversed then resulting number be "10x+y".

As given: x= 2y

        and 10x+y= 2(10y+x)-9

Now, solving the equation to get original number.

10x+y= 2(10y+x)-9

Distributing 2 to 10y and x, then opening the parenthesis.

⇒ 10x+y= 20y+2x-9

subtracting by (2x+y) on both side.

⇒ 8x= 19y-9

subtituting the value of "x", which is equal to 2y.

∴ 8\times 2y= 19y-9

⇒ 16y=19y-9

subtracting both side by (16y-9)

⇒ 3y= 9

cross multiplying

We get, y= 3

y=3

∵x= 2y

x=2\times 3= 6

∴ x= 6

Therefore, the original number will be 36 as x is the unit number and y as tenth number.

I need the answer to 7 please
bija089 [108]

7. a

Given,

Diameter = 16 feet

So, radius = 16 feet/2 = 8 feet

Circumference = 2πr

So, circumference of this circle

= 2πr

= 2 × 3.14 × 8 feet

= 3.14 × 16 feet

= 50.24 feet

b.

Given,

Diameter = 16 feet

So, radius = 16 feet/2 = 8 feet

Area = πr²

So, area of this circle

= 3.14 × (8 feet)²

= 3.14 × 64 feet²

= 200.96 feet²

Which of the following angles is coterminal with -4pi/3?<br><br> -2pi/3<br> -pi/3<br> pi/3<br> 2pi/3
PolarNik [594]
Coterminal angles are angles that end in the same position on a unit circle.

We can find angles that are coterminal to -4pi/3 by adding and subtracting 2pi.

-4pi/3 + 2pi = 2pi/3

The answer is 2pi/3

The formula for determining how long a hike will take is t=1/2(d+h) , where d is the distance in miles and h is the elevation ga
Taya2010 [7]
Answer is c.

t = 0.5(d+h)
multiply both sides by 2 to cancel out the 0.5.
2t = d+h
2t - d = h

- If you divide a number by four and then add six, you<br> get eighteen. What is the number?
stiks02 [169]

Answer:

48

Step-by-step explanation:

Create an equation to represent this, where x is the unknown number.

\frac{x}{4} + 6 = 18

Solve for x, by first subtracting 6 from both sides:

\frac{x}{4} = 12

Multiply each side by 4:

x = 48

So, the number is 48
