Answer:
51.84 cm
Step-by-step explanation:
Solution,
We have,
Area of the square= L²
According to question,
168 cm²= L²
√168 cm²= L²
√(12.96 cm)² = L
12.96 cm= L
Now,
We got,
Length of the square= 12.96 cm
By using the formula of perimeter of square,
We have,
Perimeter of square= 4L
=4×12.96 cm
=51.84 cm
Hence, the perimeter of square is 51.84 cm.
Answer:
✔️Ratio of weight to mass in simplest form: 49/5 or 49 : 5
✔️x = 110
Step-by-step explanation:
Since the ratio of weight to mass is constant, therefore we can use any pair of values from the table to find the ratio that represents the table. Let's pick the first row:
(20, 196)
Ratio of weight to mass = 196 : 20
= 196/20
= 49/5
Or 49 : 5
✔️Let's use this ratio/proportion to find x in the table
Ratio of weight to mass = 49:5
Thus:
1078/x = 49/5
Cross multiply
x*49 = 1078*5
49x = 5,390
x = 5,390/49
x = 110
Answer:
1/2 and 9 is rational but 4 is not
Step-by-step explanation:
A rational number is a number that can be written as a ratio. That means it can be written as a fraction, in which both the numerator (the number on top) and the denominator (the number on the bottom) are whole numbers.
