Answer:
<u>The length of the rectangle is 14.5√6/29 or 6.6 meters and the width is 10√6/29 or 4.55 meters.</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Area of a rectangle = 30 square meters
2. Find the length and width if the length is 1.45 times the width.
Width of the rectangle = x
Length of the rectangle = 1.45x
Now substituting in the formula of the area of a rectangle, this way:
30 = x * 1.45x
30 = 1.45x²
x² = 30/1.45
x = √30/1.45
x = 10 √6/29 or 4.55 (Rounding to two decimal places)
1.45 x = 14.5 √6/29 or 6.6
<u>The length of the rectangle is 14.5√6/29 or 6.6 meters and the width is 10√6/29 or 4.55 meters.</u>
Answer:
The new mean is 77cm
Step-by-step explanation:
If the mean height of the 30 children in a room is 76 cm, then the sum of their ages is
If James with height 107cm joins them, then the total number of children now becomes 30+1=31 and the total height becomes: 2280cm+107cm=2387cm
The new mean now becomes:
Answer:
4^12 or 16777216
Step-by-step explanation:
4^6* 4^6
We can symplify 4^6* 4^6
Since they both have the same base, we can add there exponent:
4^6* 4^6= 4^12
4^12 equals to 16777216
Answer:
10.375
Step-by-step explanation:
1.) Add up all the amount of pizzas | 12 + 9 + 11 +10+13+8+ 7,+ 13=83
2) Divide the total amount of pizzas by the amount of pizzas/amount of numbers of pizzas. | 83 divided by 8 =
10.375
