This is a right & isosceles triangle A =90° (Given) & AB = BC (given )
Apply Pythagoras
x² = 5(√2)² + 5(√2)² (since the 2 legs are equal)
x² = 5.2 + 5.2 Since (√2)² =2
x²=10 + 10 & x² = 20 & x=√(20) = 2√5 (the answer given are wrong.2√5 is the right answer)<u />
Answer: then the rocket would be 48 feet in the sky/air.
Step-by-step explanation:
Seven huge boxes and two tiny boxes total were bought by the contractor.
A linear equation is defined as an algebraic equation of maximum degree 1 is a linear equation.
According to the question, a builder needs to purchase nails to construct a house.
Both small and large boxes of nails are provided. There are 50 nails in each small box and 350 in each large box.
The contractor purchased 5 more large than tiny boxes, hence it is assumed that he purchased a certain number of little boxes.
He purchased (x+5) huge cartons.
So, 50(x) + 350(x+5) = 2590.
50x + 350x + 1750 = 2590.
400x = 2590 - 1750.
400x = 840.
x = 2.1
The bulk of the boxes he bought is 7.

Answer:
k-n+1
Step-by-step explanation:
How many numbers are written from n to k
Lets look at a smaller example with real number
Lets go from 3 to 8
3 4 5 6 7 8
There are 6 numbers
We take 8 -3 = 5, but we include the number 3 so we add it back in +1
5+1 =6
Lets look at a larger example
2 to 11
2,3,4,5,6,7,8,9,10,11
There are 10 numbers
11-2 =9 but we have to add back in the first number
9+1 =10
Now we are going from n to k
k-n = k-n, but we have to add back in the first number
k-n+1
