43. A "Square" cornfield, which means all 4 sides has the same lenght BxH
164.000 ft^2=404.96 NO
156.816 ft^2=396 Yes
174724 ft^2=418 Yes
215908 ft^2=464.66 NO
44. it's the same here, if the area is 81. then each side of the square is 9
1st figure: it has 12 sides x9 =108
2nd figure: it has 10 sides x9=90
3rd figure: has also 12 sides x9=108
45. 13^3= 13x13x13 = 2197
46. 25^2= 25x25 = 625
47. 15^3= 15x15x15 = 3375
48. 34^2= 34x34 = 1156
49. 5 root121= 5 (11)=55
50. -6.root36= - 6 (6)= -36
51. 10 root3 (8) = 10(2) = 20
52. -4. root 144= -4(12) = -48
Answer:
A
Step-by-step explanation:
Given 2 similar figures with sides in the ratio a : b
Then the ratio of their areas is a² : b²
Hence
ratio of sides = 2 : 9, then
ratio of areas = 2² : 9² = 4 : 81 → A
The answer is; 24/75 of the entire cake remained
If 2/5 of the initial cake was eaten, the 3/5 is what remained
MInu ate 1/3 of the 3/5 = 3/15
3/5 – 3/15 = 6/15 remained
Her brother ate; 1/5 of 6/15 = 6/75
6/15 – 6/75 = 24/75 remained
Answer:
There are 60 monkeys in the Zoo
Step-by-step explanation:
In this question, we are asked to calculate the number of monkeys in a Zoo given some information to use.
Let’s have the total number of monkeys be m.
60% are going monkeys. This means number of young monkeys is 0.6m.
The number of baby and old monkeys is obviously 0.4m.
Ratio of baby to old monkeys is 3:1. This means if we splitter 0.4m into 4, number of baby monkeys is 0.3m while number of old monkeys is 0.1m
Now, subtracting the number of baby monkeys from young monkeys give a total of 18 monkeys.
Let’s project this mathematically;
This means ;
0.6m - 0.3m = 18
0.3m = 18
m = 18/0.3
m = 60

Answer:
Step-by-step explanation:
A linear equation in two variables doesn't involve any power higher than one for either variable. It has the general form Ax + By + C = 0, where A, B and C are constants. ... A quadratic equation, on the other hand, involves one of the variables raised to the second power. It has the general form y = ax2 + bx + c
