Answer:
Step-by-step explanation:
<h2>4/x=2/10</h2>
cross multiplication:
4*10=2*x
40=2x
x=40/2=20
<h2>w/2 = 4.5/6.8</h2>
6.8w=2(4.5)
6.8w=9
w=9/6.8=1.32352941
Answer:
C) 0 ≤ x ≤ 25
Step-by-step explanation:
We are supposed to find a reasonable constraint so that the function is at least 300 i.e. the value of x at which f(x) is greater or equal to 300
A)x ≥ 0
Refer the graph
At x = 0
f(x)=300
On increasing the value of x , f(x) increases but at x = 12 it starts decreasing
So, x ≥ 0 can also have f(x)<300
So, Option A is wrong
B)−5 ≤ x ≤ 30
At x = -5
f(x) = 100
So, Option B is wrong since we require f(x) is greater or equal to 300
c)0 ≤ x ≤ 25
At x = 0
f(x)=300
At x = 12 , it starts decreasing
At x = 25
f(x)=300
So, The value of f(x) is at least 300 when 0 ≤ x ≤ 25
D)All real numbers
At x = 30
f(x)=0
But we require f(x) greater or equal to 300
Hence Option C is true
Answer:
8 is 4% of 200, 1% of 200 is 2
Answer:
Hello! answer: 180
Step-by-step explanation:
what I did to find answer is cut them into pieces I cut the m into 3 pieces and now just have to multiply my base x height so for the left one I did 12 x 6 = 72 for the middle I did 6 x 6 = 36 and for the right one I did 12 x 6 = 72 I add these up so...
72 + 36 + 72 = 180 so the surface area is 180! I hope this helps!
Answer:
Option D
Step-by-step explanation:
Use the Pythagorean theorem to solve this question
a2+b2=c2
c2 is always the hypotenuse, which is what we have to solve.
3^2+ 5^2=
9+25=34
Now we have to square 34 and there is our answer
