Answer:
The ratio of the area of ABCD to the area of EFGH is 9:1.
Step-by-step explanation:
Let us assume that the shapes are rectangles and they are similar. If the two shapes are similar then their sides are in the same proportion. Therefore the ratio of the sides are in the same proportion.
The area of ABCD = AB × BC = 18 × 24 = 432
The area of EFGH = EF × FG = 6 × 8 = 48
The ratio of the area of ABCD to the area of EFGH = Area of ABCD / Area of EFGH = 432 / 48 = 9/1 = 9 : 1
12.5 is already a decimal...
If you mean 12/5, then it is 2 and 2/5, which is 2.4.
If you mean 12 x 5, then it's 60.
If you mean fractions equivalent to 12.5 then it's 25/2.
If you mean decimals then 12.50, or 12.500.
Hope this helps
Answer:
x = -5/4, x= -7
Step-by-step explanation:
Using the zero product property to solve this equation,
<u>4x+5 = 0</u>
4x = -5
4x/4 = -5/4
x = -5/4
<u>x+7 = 0</u>
x = -7
Answer: Independent variable = diameter of balloon
Dependent variable = Volume
Step-by-step explanation:
Definitions:
- Independent variable : Variable that can be manipulated to see the effect in the response variable in a study.
- Dependent variable : Response variable which depends on the independent variable.
Here, diameter of balloon = Independent variable
and Volume = Dependent variable
Because volume can change with the change of diameter of the balloon.
