Answer:
Step-by-step explanation:
The ration of weight of nickel, zinc, and copper in an alloy is 4:1:2
The weight of alloy can be written as
4x + x + 2x = 35 Kg
7 x = 35 Kg
X = 35 Kg/7
X = 5kg
The weight of nickel the alloy = 4 x 5 = 20 Kg
The weight of zinc in the alloy= 1 x 5 = 5kg
The weight of copper in the alloy = 2 x 5 = 10 kg
The inequality that shows no more than $450 is to be spent on frozen treats is 0.75C + 0.85I + 0.5F ≤ 450
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Let C represent the number of chocolate fudge bars, F represent the number of frozen fruit bars and I represent the number of ice-cream sandwiches
Hence:
0.75C + 0.85I + 0.5F ≤ 450
The inequality that shows no more than $450 is to be spent on frozen treats is 0.75C + 0.85I + 0.5F ≤ 450

Answer:
Ф = ------------ = 7/5 radians
Step-by-step explanation:
"e" is inappropriate format here. Use Ф or α or similiar character for central angle.
Here, (arc length) = (radius)(central angle), or s = rФ, and so:
(central angle) = Ф = (arc length) / (radius)
7 ft
Here, Ф = ------------ = 7/5 radians
5 ft
