1) Shannon and Kristoph are dividing numbers written in scientific notation.

Mathematics
1 answer:
mihalych1998 [28]4 years ago
5 0

Answer:

<h3>(A)</h3>

The answers will have the same value, beacuse both scientific notations have the same coefficient, 4.2 and 1.4. Also, if you mentally subtract the exponents of those powers, you would have the same exponent. So, equal coefficient and equal exponent will give the same result.

<h3>(B)</h3>

The value of each expression can be found by dividing coefficients and powers.

\frac{4.2 \times 10^{9} }{1.4 \times 10^{4} }=3 \times 10^{9-4} = 3 \times  10^{5}

<h3>(C)</h3>

The value of each expression in standard form is

3 \times 10^{5}=300,000

Remember that standard form refers to the number without the ten-power.

A number increased by 9 is 13
Alborosie

Answer:

4

Step-by-step explanation:

To find the number you have to reverse the equation

Let us call the number "x"

x + 9 = 13

So to find x we flip the equation

13 - 9 = x

Solve it

4 = x

So the missing number is 4

The variable z is inversely proportional to x. When x is 19, z has the value 0.10526315789474. What is the value of z when x= 28
telo118 [61]

When two variables are inversely proportional the relation between them can be written as:

z=\frac{k}{x}

Here, k is the constant of proportionality and is always equal to the product of the two variables. So using the given values of z and x, we can find k first.

k=zx\\ \\  k=0.10526315789474(19)\\ \\  k=2

The constant of proportionality for the given inverse proportion comes out to be 2. Using the value of k in the equation, we get:

z=\frac{2}{x}

We have to find the value of z when x=28. So replacing x by 28, we get:

z=\frac{2}{28}\\  \\  z=0.07142857143

Thus, rounding of to nearest thousand the value of z comes out to be 0.071 if x is equal to 28.
