Answer:
it's 700 so last one
Step-by-step explanation:
since it's 1 to 20 you multiply 35×20 and you get 700
10-5(x-2)/5=1/10(x+1)
10-5(x-2)/5=x+1/10
10(4-x)=x+1
40-10x=x+1
40=x+1+10x
40=11x+1
40-1=11x
39=11x
x=39/11
Answer:
the first one that looks like a star
Step-by-step explanation:
because the shape on the base is a pentagon for the pyramid, and look for another pentagon in the middle of the images in the anwser choice and you find the first one is correct
Answer:
Step-by-step explanation:
Area of a circle is defined as
A = πr²
Where
A is the area of the circle
r Is the radius of the circle
π is a constant = 3.142
Then,
Given that the area is 380 in²
So,
A = πr²
380 = 3.142 × r²
Divide both side by 3.142
380 / 3.142 = 3.142 × r² / 3.142
111.372 = r²
Take square root of both sides
√111.372 = √r²
10.5533 = r
r = 10.5533 in
Nearest hundredth means to 2d.p
Therefore
r = 10.55 inches
