Answer:
20
Step-by-step explanation:
Scale factor = 8/16 = 1/2
So, 10/x = 1/2
x = 10*2
x = 20
Answer:
Total Fencing Cost =$19.57
Step-by-step explanation:
If Rosalina is planning on fencing, we are talking about the Perimeter of the Flower Bed
Radius of the circular flower bed =3.5 ft
Perimeter = 
If Wire fencing Cost $0.89 per foot
Total Fencing Cost = $0.89 X 21.99=$19.57
To convey as an algebraic expression simply break down the statements and use any variable to represent the number in the sentence.
10 • x^2 = 40x
10x^2 = 40x
10x^2 - 40x = 0
10(x^2 - 4x) = 0
X(x - 4) = 0
X = 0
X - 4 = 0
X = 4.
Here are two possibilities of what the number can be, but because it is a nonzero number, I believe it would be 4.
If you know the definition of expand (to increase or make bigger)
then this will be easy.
when ever it asks for expanded for that means your answer has to be bigger than the number your given.
for your question:
you have 7,080,267
so u first do the biggest value which is the first 7 on the left.
and then work your way down to the smallest which would be 7 on the right.
7000000
000000
80000
0000
200
60
7
that is the numbers expanded
but now u have to write it in the fom so you just add a + after each number
7000000+000000+80000+0000+200+60+7
you can shorten it by removing the numbers with no value:
7000000+80000+200+60+7
Answer:
91
Step-by-step explanation:-5, 1, 7, 13
the common diference is : d = ( 13)-(7)=(7)-(1)=(1)-(-5)=6
the firt term is A1 = -5
the n-ieme term is : An = A1 +(n-1)d
An = -5+6(n-1)
An = 6n-11
the 17th term in the arithmetic sequence is : A17 = 6(17)-11 =91
