Answer: 54 square yards
Step-by-step explanation:
Given: The area of the scale model of a playground is 6 square yards.
let l be the length and w be the width of the model of playground.
then .....(1)
The scale model is enlarged by a scale factor of 3 to create the actual playground.
Then length of playground = 3l
width of playground = 3w
Then the area of the playground=
By using (1), we get
The area of the playground=
Answer:
Step-by-step explanation:
1. Symbolically, we get: 62 - 5x < 40
2. y - 7.3 < 3.4. Solve for y by adding 7.3 to both sides, obtaining:
y < 10.7 This is both the 'range' and the 'solution'
3a) 4b = 9b + 45, or -5b = 45, or b = -9
3b) 5a + 10 = 4a - 4
Combining like terms results in a = -14
To eliminate the i in the denominator, you multiply it by (6+5i), because (a+b)(a-b)=a²-b², we need i² to eliminate i. Recall that i²=-1
-1(6+5i)/(6-5i)(6+5i)=(-6-5i)/[6²-(5i)²]=(-6-5i)/(36-25i²)=(-6-5i)/61
your choices are all correct. You need to check the 7th answer as well.
