We are given the expanded form and we need to write the standard form:
10 + 8x(1/10) + 3 x(1/100) + 9 x (1/1000)
So, that is:
10 + 0.8 + 0.03 + 0.009
= 10.839

A plot of land has an area of 1,089,000 square feet.The conversion factors between different area measures are shown below.27,87

IgorC [24]

Part A) 24.79 acres

1) Since that plot has an area of

$1,089,000ft^2=1.08\times10^6ft^2$

And the number of units must be between 10 and 10² units.

Part A)

$\begin{gathered} 27,878,400ft^2=2.78784\times10^7ft^2=1m^2 \\ 43560ft^2\text{ =4.356 }\times10^4ft^2\text{ = 1 acre} \end{gathered}$

2) Let's convert them to the apparently plausible units, see if it fits within the given interval.

$\begin{gathered} \frac{1.08\times10^6}{4.356\times10^4}=24.79\text{ acres} \\ \frac{1.08\times10^6}{2.78784\times10^7}=0.03m^{2} \end{gathered}$

We can see that 0.03 m² does not belong to the given interval.

3) Hence, the answer is 24.79 acres.

Rewrite the equation below so that it does not have fractions.

Ray Of Light [21]

Answer:

x=17/14

Step-by-step explanation:

(7/9)x+2=(5/6)

18 is the least common multiple between 9 and 6, so we can multiply each fraction by 18.

7 18 126

---- * ------ = -------- = 14

9 1 9

14x+2=(5/6)

5 18 90

---- * ------ = --------- = 15

6 1 6

14x+2=15

14x=17

x=17/14

Hope this helps!

Find the missing exponent. Explain 5^11/5^?=5^4

ruslelena [56]

Answer:

The missing exponent is 5^7

Step-by-step explanation:

5^11/5^?=5^4

1. Subtract the exponents from each other.

11-4=7

2. Plug 7 in as the exponent.

5^11/5^7

3. 11-7=4 therefore, 5^11/5^7 equals 5^4.

Which equation would help find the measure of ZM?

3241004551 [841]

Answer:

$\huge \boxed{ \boxed{ \sf x + 52 ^{o} + 7 {2}^{o} =18 {0}^{o} }}$

Step-by-step explanation:

<h3>to understand this</h3><h3>you need to know about:</h3>

triangle
equation
PEMDAS

<h3>given:</h3>

$\angle V=52°$
$\angle P=78°$

the equation

<h3>tips and formulas:</h3>

a triangle contains 180°

<h3>let's solve:</h3>

$\text{since a triangle contains 180° the sum of the interior angles has to be 180°}$

$\text{therefore the equation is}$

$\mathfrak{x + {52}^{o} + {78}^{o} = 180 ^{0} }$
