Answer:
d. 80
Step-by-step explanation:
Similarity ratio of ABCD to EFGH = 4:3.
This implies that the ratio of AD to EH = 4:3
If EH = 60, then:
AD:60 = 4:3
AD/60 = 4/3
Multiply both sides by 60
AD = ⁴/3 × 60
AD = 80
Answer:
No, diagonal of square C is 70.71ft
Step-by-step explanation:
Given in the question that length of one square = 5 ft
Length of Square C = 10 small squares
1 square = 5 ft
10 square = 5ft * 10
= 50 ft
As we know that in a square all side are of equal length and make an angle of 90° at each corner.
So, by using pythagorus theorem
Diagonal of square² = side² + side²
Diagonal of square² = 2side²
Diagonal of square = √(2side²)
Diagonal of square = √2 (side)
where side = 50 ft
Diagonal of square = √2 (50)
Diagonal of square = 70.71 ft
x^2 - 3x -28 ≥ 0
factor
(x-7) (x+4) ≥ 0
x=7 x=-4
we have three regions where the answers can lie
x<-4 between -4 and 7 and x>7
pick a point and see if it works
x=-10
(-10-7) (-10+4) ≥ 0
negative * negative is greater than 0 so this is a solution x< -4
x=0
(0-7) (+4) ≥ 0
negative * positive is less than 0 so this is not a solution
x=10
(10-7) (10+4) ≥ 0
positive * positive is greater than 0 so this is a solution x>7
We have two regions that work
x<-4 and x>7
The solution set for the given inequality is 
<u>Given the following inequality:</u>
<h3>What is an inequality?</h3>
An inequality can be defined as a mathematical relation that is typically used to compare two (2) integers or variables in an equation by illustrating any of the following:
- Greater than or equal to the other (≥).
- Less than or equal to the other (≤).
Simplifying the inequality, we have:
