Rational number between 1/8 and 1/4

Answers

Answer 1
Answer: one way is to find them with common denomenator so
1/8 ad 1/4
1/4=2/8
between 1/8 and 2/8
make them smaller
1/8=2/16
2/8=4/16
between 2/16 and 4/16=3/16

the answe ris 3/16

83 less than a number n

Answers

The answer could be anything. If there is no number for n, then you probably need to make one up. For example, 83 less than 123 is 40. So, if it did give you a number, comment it and I will help you further. Hope this helps. :)

Answer:

the answer is 83-n

What is the length of the radius, r?

Answers

The length of the radius would be 18cm long

Answer:

18 cm

Step-by-step explanation:

The circumference (C) of a circle is calculated as

C = 2πr ← r is the radius

Given

C = 36π, then

2πr = 36π ( divide both sides by 2π )

r = (36\pi )/(2\pi ) = 18

What time is 3 hours and 30 minutes after 6:50 a.m.

Answers

3 + 6 = 9
30 + 50 = 70
9:70 would be 10:10 am
add 3 hours to 6:50.
then add 30 minutes to 50 which would make it 80.
subtract 80 from 50, it would make it 30.
you subtract 10 from 30 and your answer is 20.
ANSWER: 10:20a.m

Hugo is mixing blue paint with red paint to create purple paint. The ratio of blue to red is 3 to 2. How many pints of blue paint will he use to create 40 pints of purple paint?

Answers

Answer:

24 pints of blue paint used  to create 40 pints of purple paint .

Step-by-step explanation:

As given

Hugo is mixing blue paint with red paint to create purple paint.

The ratio of blue to red is 3 to 2.

Let us assume that the x be scalar mutiple .

Thus

Pints of blue paint used = 3x

Pints of red paint used = 2x

As given 40 pints purple paints is made by mixing  blue paint with red paint .

Than the equation becomes

2x + 3x = 40

5x = 40

x = (40)/(5)

x = 8

Thus

Pints of blue paint used = 3 × 8

                                        = 24 pints

Therefore 24 pints of blue paint used  to create 40 pints of purple paint .


24 pints of blue paint. Idk of this is a solid way to get the answer, but I added 3+2=5. then 40/5=8. Then multiplied 8*3=24 and 2*8=16

The length of the hypotenuse of a right triangle is 20 feet and the length of one leg is 16 feet find the length of the other leg

Answers

This is a problem for which you will have to use the Pythagorean theorem.

The Pythagorean theorem states that:

x^2 + y^2 = h^2

where x and y are the legs, and h is the hypotenuse.

Let h = 20 ft, and x = 16

16^2 + y^2 = 20^2

Now, solve for y.

256 + y^2 = 400.
256 - 256 + y^2 = 400 - 256
y^2 = 144
y = 12

The length of the other leg is 12 feet.

Sam measured the height of a window frame as 5.23 feet, but the actual height was 6 feet. What is the percentage of error in Sam's measurement?

Answers

Answer: 12.83%

Step-by-step explanation:

Given : Sam measured the height of a window frame as 5.23 feet, but the actual height was 6 feet.

i.e. Estimated height = 5.23 feet

Actual height = 6 feet

Then, the percentage of error in Sam's measurement will be :-

\%\text{Error}=\frac{|\text{Estimated height-Actual height}|}{\text{Actual height}}*100\n\n=(|5.23-6|)/(6)*100\n\n =(0.77)/(6)*100\n\n=12.8333333333\approx12.83\%

Hence, the percentage of error in Sam's measurement= 12.83%

Answer:

12.83%
