Answer:
7*10*10*10 = 7000
7*10 = 70
70*10 = 700
700*10 = 7000
Step-by-step explanation:
The given expression is:
7*10^3
Here 10^3 means that 10 will be multiplied 3 times:
7*10*10*10 = 7000
How did we get 7000?
7*10*10*10 = 7000
7*10 = 70
70*10 = 700
700*10 = 7000
We can also say that there are 7 1000s in 7000....
I was on the right track, lol. 280.5 miles.

Step-by-step explanation:
Answer:
The length of the longer base he 35 units
Step-by-step explanation:
Here, we want to find the length of the longer base of the trapezoid
Mathematically, we can find the area using the formula;
1/2( a + b) h
where a is the shorter base
b is the longer base
h is the height
Let the shorter base be x
The other base is 5 times this length and that makes 5 * x = 5x
Height is the average of both bases;
(x + 5x)/2 = 6x/2 = 3x
Substituting these in the formula, we have ;
1/2(x + 5x)3x = 441
3x(6x) = 882
18x^2 = 882
x^2 = 882/18
x^2 = 49
x^2 = 7^2
x = 7
But the longer base is 5x and that will be 5 * 7 = 35 units
