1.625 as a fraction is 1 5/8

15/8 simplified is 1 7/8

if you are using the word "and" to represent multiplication here you go:

first i would change both fractions to a mixed number

13/8×15/8=195/64
simplify

your answer would be 3 3/64

if you are using "and" to represent adding here you go:

1.625 as a fraction is 1 5/8

first i would change 1 5/8 to a mixed number:  13/8

so then add 15/8+13/8=28/8

simplify:  
28÷4=7
8÷4=2

7/2=3 1/2
  
i hope this helped

Find the range of ƒ(x) = –x + 4 for the domain {–3, –2, –1, 1}.
qaws [65]

Answer:

range {3, 5, 6, 7 }

Step-by-step explanation:

to find the range substitute each value of x from the domain into f(x)

f(- 3) = -(- 3) + 4 = 3 + 4 = 7

f(- 2) = - (- 2 + 4 = 2 + 4 = 6

f(- 1) = - (- 1) + 4 = 1 + 4 = 5

f(1) = - 1 + 4 = 3

range y ∈ { 3, 5, 6, 7 }

Evaluate: 5–^2 = <br> WILL MARK AS BRAINLIEST
Elanso [62]

When you have a negative exponent, you move it to the other side of the fraction to make the exponent positive.

For example:

x^{-2} or \frac{x^{-2}}{1}=\frac{1}{x^2}

\frac{1}{y^{-2}}=\frac{y^2}{1}  or  y²



So:

5^{-2}=\frac{1}{5^2}=\frac{1}{25}

Your answer is B

How do i solve divide 5/8 by 50%
Ede4ka [16]
50% is \frac{50}{100}
We have two ways to do this, pick your favor:
either by fractions:
\frac{5}{8} ÷ \frac{1}{2}
(\frac{50}{100} =  \frac{1}{2}
Multiply by the reciprocal of \frac{1}{2} which is 2(flip it)

\frac{5}{8} × 2 = \frac{5}{4} = 1.25

Or change them to decimals:
\frac{5}{8} = 0.625
\frac{50}{100} = 0.5

0.625 ÷ 0.5

0.5 I 0.625
multiply by 10 to make it easier to divide(it still gives us the same answer)
0.5 × 10 = 5
0.625 × 10 = 6.25
     1.25
5 I 6.25
    -5
     12
    -10
       25
      -25
         0

0.625 ÷ 0.5 = 1.25

The equation below shows the total volume (V), in cubic units, of 2 identical boxes with each side equal to s units:
trasher [3.6K]
Start with the equation,

V = 2s^3

Now substitute s with 3.5 units and evaluate the expression.

V = 2 * (3.5 units)^3

V = 2 * 42.875 units^3

V = 85.75 units^3

Answer: The volume is 85.75 cubic units

The growth of a strain of bacteria can be modeled by the function graphed, where the x-values are the time in seconds and the y-
Andrew [12]

There are (A) 2.7 bacterias initially.

<h3>What is a function?</h3>
  • A function is an expression that establishes the relationship between the dependent and independent variables.
  • A function from a set X to a set Y allocates exactly one element of Y to each element of X.
  • The set X is known as the function's domain, while the set Y is known as the function's codomain.
  • Originally, functions were the idealization of how a variable quantity depends on another quantity.

To find the number of bacteria:

  • The graph shows that the function follows an exponential curve, and the starting point is at ( 0,2.7 ).
  • The starting number of bacteria is then 2.7.

Therefore, there are (A) 2.7 bacterias initially.
