1.04*10^9=1,040,000,000 by moving the decimal 9 spots to the right.

One million is 1.000,000, 100 million is 100,000,000, 1 billion is 1,000,000,000, and 10 billion is 10,000,000,000. Since this has the same number of digits as 1 billion and is closer to 1 billion than 10 billion due to that the second digit is lower than 5, our answer is C

it takes someone 15 minutes to prepare 3 1/4 cups of juice how many hours would it take to prepare 32 1/2 cups of juice

wariber [46]

$\bf \begin{array}{ccll} minutes&\stackrel{juice}{cups}\\ \cline{1-2} 15&3\frac{1}{4}\\\\ x&32\frac{1}{2} \end{array}\implies \cfrac{15}{x}=\cfrac{3\frac{1}{4}}{32\frac{1}{2}}\implies \cfrac{15}{x}=\cfrac{\frac{3\cdot 4+1}{4}}{\frac{32\cdot 2+1}{2}}\implies \cfrac{15}{x}=\cfrac{\frac{13}{4}}{\frac{65}{2}}$

$\bf \cfrac{15}{x}=\cfrac{~~\begin{matrix} 13 \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~}{\underset{2}{~~\begin{matrix} 4 \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~}}\cdot \cfrac{~~\begin{matrix} 2 \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~}{\underset{5}{~~\begin{matrix} 65 \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~}}\implies \cfrac{15}{x}=\cfrac{1}{10}\implies 150=x\leftarrow \begin{array}{llll} \textit{150 minutes or}\\\\ \textit{2 hours and a half} \end{array}$

How many 1 2/3 are in 1 1/6

Flura [38]

Answer:

7/10

Step-by-step explanation:

To find how many of x are y, you solve y/x.

With our numbers, we have 7/6 ÷ 5/3.

We can turn that into 7/6 × 3/5 = 21/30 = 7/10.

Which of the following expressions should be simplified using the zero power property? Select all that apply.

lys-0071 [83]

The expressions that should be simplified using the zero power property are ( r⁶ )⁰, (l⁷/l⁷), and m².m⁻². The correct options are A, C, and E.

<h3>What is an expression?</h3>

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

The expressions that should be simplified using the zero power property are:-

( r⁶ )⁰ = r⁰ = 1

(l⁷/l⁷) = l⁷⁻⁷ = l⁰ = 1

m².m⁻² = m²⁻² = m⁰ = 1

Therefore, the expressions that should be simplified using the zero power property are ( r⁶ )⁰, (l⁷/l⁷), and m².m⁻². The correct options are A, C, and E.

Write an expression for the model. Find the sum.

dedylja [7]

C)2+(-3);-1
If you look at the model you see it meets at zero both ways go to -1 and 2 but when you travel to -1 its -3 because you move backwards on the model
