Answer:
Step-by-step explanation:
a. Given that the area's are in the ratios 16:81.
-Area is two-dimensional while perimeter is one-dimensional
=>The perimeter's of the two polygons will vary in a ratio equal to the square root of their area's ratio:
We use the perimeter ratio to find the perimeter of the larger polygon:
Hence, the perimeter of the larger polygon is 954 ft
b -Given the area of the larger polygon is 4779 ft2, the smaller polygon can be determined using the area ratio 16:81
Hence, area of the smaller polygon is
Answer:
5x5=25 thanks for the points
Answer:
B.He did not add the corresponding parts of the complex numbers.
Step-by-step explanation:
A mid point is a point that is of equal distance to two reference points.
Given: Find the midpoint of 5+(-3)i and 12+7i.
These expressions have two parts: the value and complex number parts.
Thus the addition ought to have been;
(5+(-3i)) + (12+7i) = (5 - 3i) + (12 + 7i)
= (5 + 12) + (-3i + 7i)
= 17 + 4i
The midpoint can be determined as:
Thus it can be observed that Raul did not add the corresponding parts of the complex numbers.
Answer:
John paid $127 for football camp. He paid a $7 registration fee and $5 for each week he was enrolled in camp. What is w, the number of weeks John was enrolled in football camp?
The figures are similar. Place each rectangle's sides as fraction, and make them equal to each other
18/27 = 6/x
cross multiply
18(x) = 6(27)
Multiply
18x = 162
Isolate the x. Divide by 18
18x/18 = 162/18
x = 9
To calculate the area, multiply 9 with 6
9 x 6 = 54
(A) 54 is your answer

1 inch = 15 feet
1/4(15) = 3.75 in.
1/3(15) = 5
The actual dimensions are B) 3.75 ft by 5 ft
