What is larger  3/8  or  5/16

Answers

(3)/(8) ... (5)/(16)

First, find the least common denominator between the two.
Since 8 is a factor of 16, the LCD is 16.

(3*2)/(8*2)

(3)/(8)= (6)/(16)

Now, you can compare the numerators.

6>5

Since 6 is greater than 5, you know that (6)/(16) > (5)/(16).

Therefore, we now know that (3)/(8) is larger.

3/8 is larger than 5/16.

Given are two fractions 3/8 and 5/16, we need to determine which is larger one,

To determine which fraction is larger between 3/8 and 5/16, we can compare their values.

First, let's find a common denominator for both fractions. The least common multiple (LCM) of 8 and 16 is 16.

We can convert both fractions to have a denominator of 16:

3/8 = (3/8) x (2/2) = 6/16

5/16 = 5/16

Now, we can see that 6/16 is larger than 5/16.

In general, when comparing fractions with the same denominator, the fraction with the larger numerator is greater.

However, when the denominators are different, as in this case, we need to convert the fractions to have the same denominator before comparing them.

Therefore, 3/8 is larger than 5/16.

Answers

Step-by-step explanation:

let's find the circumference of the semi circle. as it's a parallelogram opposite sides are equal. therefore 2 semicircles will have the same circumference

circumference of circle = 2pi r

circumference of half circle = half of circle= pi r

circumference of half circle = 22/7 × 4 ( diameter is 8 therefore radius is half of that)

circumference of half circle = 88/7

this image has 2 half circles with same radius

now find the perimeter of total figure

perimeter= 9+ 9+ 88/7 +88/7

= 18 + 176/7

= 18+ 25.14

= 43.14

to nearest tenth place = 43.1

Answer:

8+8+9+9

If 8 is the diameter then that's the answer

Line BC reflects about a line such that N is the reflection of B and O is the reflection of C. Point N is shown on the coordinate plane, but point O is not. What will the coordinates of point O be?(1, 5)
(3, 5)
(5, 5)
(6, 5)
(5,5)
(3,5)

Answers

    If the line BC reflects about a line and point N( 3, 5 ) is the reflection of point B ( 3 , 7 ) then the reflection of C ( 5, 7 ) is O ( 5 , 5 ).
Answer: C ) ( 5, 5 ) 

Answer:

(5,5)

Step-by-step explanation:

Given that B has coordinates as (3,7) When reflected about a line the new coordinates are (3,5)

This implies that by reflection x coordinate remains the same but y reduced by 2 units.

Apply the same logic for unknown O.

C is reflected to O.

Original coordinates of C are (5,7)

Hence new coordinates i.e. that of O would be

x coordinate same as 5

y coordinate 2 less = 7-2 = 5

COordinates of O are (5,5)

If f(x)=log2(x+4), what is f^-1(3)?

Answers

f\left( x \right) =\log _( 2 ){ \left( x+4 \right)  } \n \n \log _( 2 ){ \left( x+4 \right)  } =y\n \n { 2 }^( y )=x+4

\n \n x={ 2 }^( y )-4\n \n \therefore \quad { f }^( -1 )\left( x \right) ={ 2 }^( x )-4\n \n \therefore \quad { f }^( -1 )\left( 3 \right) ={ 2 }^( 3 )-4=4

The value of f^-1(3) is 4

What are inverse functions?

The inverse of a function f(x) is the opposite of the function

How to determine the inverse function?

The functionf(x)is given as:

f(x) = log_2(x + 4)

Express f(x) as y

y = log_2(x + 4)

Swap the positionsof x and y

x = log_2(y + 4)

Express as exponents

2^x = y + 4

Make y the subject

y = 2^x - 4

Express the equationsas an inverse function

f^(-1)(x) = 2^x - 4

Substitute 3 for x in the above equation

f^(-1)(3) = 2^3 - 4

Evaluate

f^(-1)(3) = 4

Hence, the value of f^-1(3) is 4
