Answer:
3/25
Step-by-step explanation:
You know that percent is out of 100, so that's 12/100
Then simplify the fraction to 6/50 then 3/25
Answer:
Cost of procedure is $45
Step-by-step explanation:
In this question, we are concerned with finding the cost of the procedure, given the tip amount and the percentage of which it is of the procedure cost.
From the question, we are told that the cost of the procedure is b
Mathematically, 12% of b = tip
Thus,
12/100 * b = 5.4
12b = 5.4 * 100
12b = 540
b = 540/12
b = $45
Yes because there are a lot of students and many are going to say yea
9+9+9+9+9=45 I'm not sure if that's what they're asking for
Hello!
To find the surface area you can divide the prism into the 2D shapes it is made of
First list out all the shapes
2 triangles with bases of 18 and heights of 15.6
3 rectangles with side lengths of 20 and 18
First find the area of the triangles
The equation to find the area of a triangle is
A is area
h is height
b is base
Put in the values you know
Solve
A = 140.4
The triangles have an area of 140.4 units
Next we find the area of a the rectangles
To do this we multiply the sides
18 * 20 = 360
The rectangles have areas of 360 units
Now we add all the areas
There are 2 triangles and 3 rectangles
140.4 + 140.4 + 360 + 360 + 360 = 1360.8
The answer is B) 1360.8cm squared
Hope this helps!
