1 rod or long is a column of 10 unit cubes.
10 longs placed side by side, form a flat (with dimensions 10×10)
10 flats, placed on top of each other form a large cube, with dimensions 10×10×10 = 1000 cubes.
-------------------------------------------------------------------------------------------------
each small cube (unit cube) represents the number 1.
thus each long represents 10
each flat represents 100
and each large cube represents 1,000
The number 13,450 can be written as
1*10,000+3*1000+4*100+5*10 using the expanded form.
This means that there are 13 large cubes, 4 flats and 5 longs needed to model the number.
Answer: 13 large cubes, 4 flats, 5 longs
Answer: Good for her, thats a lot of money
Step-by-step explanation:
If the question is:
Mrs.baxter deposits 2000 into an account that earns 5% simple interest how much is mrs baxters investment worth after 8 years
the the answer is:
$5000
2x+9+8x+1=180
2x+8x+9+1=180
10x+10=180
10x=170
X=17
<span>First we calculate z using the formula:
z = (x - μ)/σ</span>
Where:
x = our variable, 10
μ = mean, 8
σ = standard dev, 2
Substituting known
values:<span>
z = (10 - 8)/2
z = 2/2
z = 1
Using the tables of
the normal distribution to find the p-value with z = 1
p = 0.8413
Since we want
"greater than 10”, we need to subtract the probability from 1
therefore
p* = 1 - 0.8413 = <span>0.1587</span></span>
Answer:
Solve for the first variable in one of the equations, then substitute the result into the other equation.
Point Form:
(
7
/10
,
2/1
5
)
Equation Form:
x
=
7
/10
,
y
=
2/1
