Use this. It’s really good
Answer:
Yes
Step-by-step explanation:
You can check whether the ratios form a proportion, by setting one piece of the ratios as x
Thus, we can use the equation 4/3.2=22/x.
From this, we get 4x=70.4.
Solving for x gives us 17.6.
Answer:
17/5
Step-by-step explanation:
23=5x+6
23-6=5x
17=5x
X=17/5
I think that the answer is negative 11 over 12
The formula for the volume of a sphere is the following:
Plug in V=5000π and solve for the radius.
Divide both sides by
Multiply both sides by 3/4 (to eliminate the 4/3 on the right side)
Also, flip the equation so we have the unknown variable on the left side (math etiquette).
Take the cube root of both sides
Now, calculate the surface area since now we know the radius.
The formula for the surface area is the following:
Plug in r=15.5
The second choice is your answer.
