Answer:
1/2
Step-by-step explanation:
0.5 is also the same as 1/2 in simplest form.
The correct answer is 4.8 hours
Explanation:
This mathematical problem can be solved by using the rule of three, which involves finding an unknown value by using three related values. The process is shown below:
1. It is known a fully charged battery (100% battery) lasts 16 hours. This can be represented as 100 = 16. But it is not know how much a 30% battery last; this can be represented as 30 = x.
2. Write all the values
100 = 16
30 = x
3. Cross multiply to create an equation and solve the equation
100 x = 48
x = 480 / 100
x = 4.8
Answer: No, Kate can't completely cover the shape.
Step-by-step explanation:
S=Area of Square. T=Area of each Triangle. A=Total Area
S=6*6
S=36 in^2
T=1/2 * 6 * 7.5
T=3*7.5
T=22.5 in^2
4T=4*22.5
4T=90 in^2
A=4T+S
A=90+36
A=126 in^2
120<126 ==> No, Kate can't completely cover the shape.
