No whole numbers do as if you look at the factors pairs of 45 none of them add to 17:
1, 45 = 46
3, 15 = 18
5, 9 = 14
The two numbers that add to 17 but multiply to 45 are can be calculated using the quadratic formula and are actually 13.72 and 3.28
The answer is A,
Your farthest x value is -2
1).2:5
2). If pan has 40 dollars in her account that means her brother has 100 dollars since all your doing is 20×2=40 20×5=100
3). Im not sure about this one but I assume it is 4:10
(I dont know what a tape diagram is but I hope this helped).
The maximum angle of repose is the<span> maximum angle at which a material can be piled without slumping. The material piled up will form a cone.
If we project the situation on a 2D plane, we get a triangle rectangle (see picture attached). We know one angle and the Opposite side (height) and we need to find the Adjacent side (radius).
Recalling trigonometry formulae:
tan</span>α = O / A
Solving for A:
A = O / tan<span>α
We can now substitute our data (O = 20):
</span>1) Sand, Bank Damp
<span>α = 45°
A = 20 / tan(45)
= 20
The radius is
20 feet.
</span>
2)Sand, Bank Dry
α = 35°
A = 20 / tan(35)
= 28.5629
The radius is
28.6 feet.
3) Sand, core
α = 41°
A = 20 / tan(41)
= 23.0074
The radius is
23 feet.
4) Sand, foundry prepared
α₁ = 30°
A₁ = 20 / tan(30)
= 34.6410
α₂ = 44°
A₂ = 20 / tan(44)
= 20.7106
The radius is between
20.7 and 34.6 feet.
5) Sand, Foundry shakeout
α = 39°
A = 20 / tan(39)
= 24.6979
The radius is
24.7 feet<span>.</span>
