Answer:
Anything above 9
Step-by-step explanation:
63/7=9
Answer
4. E
use PEMDAS
5. 36+18=54 so C
plug in x
6. 15=5x
x=3 so C
11. B
break the absolute value into pos and neg components
12.D
is not equal to so open circle
2x=14
2x=8
so 4 and 7 with open circles
Step-by-step explanation:
B. The sum of x and 0.6 multiplied by 3 is equal to 7

Answer:
x=1/4 or x=-1
Step-by-step explanation:
x−
1
x
+3x+3=0
4x2+3x−1
x
=0
Step 1: Multiply both sides by x.
4x2+3x−1=0
(4x−1)(x+1)=0(Factor left side of equation)
4x−1=0 or x+1=0(Set factors equal to 0)
x=

Answer:
75 ft
Step-by-step explanation:
Here we are given a right angled triangle with a known angle of 20°, length of the hypotenuse to be 80 and we are to find the length of the base x.
For that, we can use the formula for cosine for which we need an angle and the lengths of base and hypotenuse.
So putting in the given values to get:
Therefore, the value of x is the closest to 75 ft.
Answer:
Therefore the radius of the can is 1.71 cm and height of the can is 2.72 cm.
Step-by-step explanation:
Given that, the volume of cylindrical can with out top is 25 cm³.
Consider the height of the can be h and radius be r.
The volume of the can is V=
According to the problem,
The surface area of the base of the can is =
The metal for the bottom will cost $2.00 per cm²
The metal cost for the base is =$(2.00× )
The lateral surface area of the can is =
The metal for the side will cost $1.25 per cm²
The metal cost for the base is =$(1.25× )
Total cost of metal is C= 2.00 +
Putting
Differentiating with respect to r
Again differentiating with respect to r
To find the minimize cost, we set C'=0
⇒r=1.71
Now,
When r=1.71 cm, the metal cost will be minimum.
Therefore,
⇒h=2.72 cm
Therefore the radius of the can is 1.71 cm and height of the can is 2.72 cm.
