Answer:
5
Step-by-step explanation:
Calculate the distance between the points using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (0, 5) and (x₂, y₂ ) = (- 5, 0)
d = 
= 
= 
= 
= 5 ← exact value
Perimeter of rectangle = all sides added
= 3+3+7+7 =20
volume of sphere = 4/3 x π x r(cubed)
= 4/3 x π X 4(cubed)
= 268.08257
area of triangle = base x height / 2
= 5 x 6 / 2
=30/2 =15
volume of pyramid = base height x base width x height / 3
= 300
side of triangle ---> use Pythagoras theorem so a(squared) + b (squared) = c(squared)
4(squared) + 3(squared) = c(squared)
16 + 9 = c(squared)
25 = c(squared)
c = 5

Hello,
The camera is $150
The discount is 30%
First multiply the % by 100 to get a decimal
150 * 0.30 = 45
-----------------------------------------------------------------------------------------------------------------
The Camera now costs $105
The discount price was $45
Hope this helps

6.4/8 = y/6 = x/7
0.8/1 = 4.8/6 = 5.6/7
6.4/8 = 4.8/6 = 5.6/7
x = 5.6 ; y = 4.8
I think that’s how you do it but not 100% sure
5n+5=45
Subtract 5 from both sides
5n=40
Divide both sides by 5
n=8
I hope this helps
