A submarine starts at 0 units and has groups of 3 floats and groups of 4 anchors attached.
Using these groups of floats and anchors, write as many different expressions as you can that would make the submarine's final position -5 units.
write three expressions
Answers
Answer:
-12
Step-by-step explanation:
The three equivalent expressions of the final position are:
-(5)(3) - (2)(4), -(5)(3) + (-2)(4) and -(5)(3) + (2)(-4)
From the question,
Each float takes a step of 5 unitsEach group takes a step of 2 unitsSo, the final position of the submarine is:
Final = -(5)(3) - (2)(4)
The minus "-" sign implies that the submarine moves downwards i.e. it sinks
The equivalent expressions of the final position are:
-(5)(3) - (2)(4), -(5)(3) + (-2)(4) and -(5)(3) + (2)(-4)

Please help! I need to tell whether x and y are in a proportional relationship and I need to write an equation that represents the relationship if it’s proportional.
Answers
Answer:
It is a proportional relationship
Step-by-step explanation:
To see if multiple ratios are proportional, you could write them as fractions, reduce them, and compare them. If the reduced fractions are all the same, then you have proportional ratios.The equation that represents a proportional relationship, or a line, is y=kx, where k is the constant of proportionality.

The greatest value of y is y=___, and it occurs when x=
For x between x = π and 2π, the function value y ___ 0
Answers
Answer:
1) Cos
2) 1
3) π
4) 1
5) y < 0
Step-by-step explanation:
1)
Cos
2)
The y-intercept is the value of y when x=0, ie the value of y when the line meets the y-axis. We can see from the graph that this is 1.
3)
The x-intercept is the value of x when y=0, ie the value of x when the line meets the x-axis. We can see from the graph that the smallest positive value of x when the line crosses the x-axis is π.
4)
Highest y value from graph is 1, and besides, for cos graphs, y≤1.
5)
We can see from the graph that between x=π and x=2π, the function is bellow the y-axis, ie y<0.
The graph is of a cos function. The y-intercept of the graph is the function value y=1. The smallest positive x-intercept of the graph is located at x=π. The greatest value of y is y=1, and it occurs when x=2π. For x between x = π and 2π, the function value y<0.
The point on the graph where it crosses the y-axis is known as the y-intercept. The y-intercept in this situation is zero since the graph crosses the y-axis at (0, 0).
The point at which the graph first crosses the x-axis at a positive value of x is known as the graph's smallest positive x-intercept. The graph in this instance crosses the x-axis at (x,0), making the smallest positive x-intercept.
The maximum value of the function is equal to the highest value of y. The greatest value of y in this situation is 1, and it happens when x = 2.
The function value y declines from 1 to 0 for x between x = and 2. You can observe this by examining the graph.

Step-by-step explanation:
2 5 ( 2 − 1 2 ) = − 2 8
2 ( 2 − 1 2 ) 5 = − 2 8
4 − 2 4 = − 1 4 0
4 − 2 4 + 2 4 = − 1 4 0 + 2 4
2 ( 2 − 1 2 ) 5 = − 2 8
4 − 2 4 5 = − 2 8
4 − 2 4 5 = − 2 8
5 ⋅ 4 − 2 4 5 = 5 ( − 2 8 )
4 − 2 4 = − 1 4 0
4 − 2 4 = − 1 4 0
4 − 2 4 + 2 4 = − 1 4 0 + 2 4
4 = − 1 1 6

20+130+h =180
when you solve you get h=50
130+g = 180
g= 50
50+60+f = 180
f=70
as the summation of all angles in a triangle must be 180
∠H = 180 - (130 +20)
= 180-150
=30
as the straight line has an angle of 180
∠G= 180 - 130
= 50
since that
∠f = 180- (50+60)
=180- 110
=70

6. A factory has two types of machines.
• The factory has 6 cutting machines and 4 stamping machines.
• Each cutting machine cuts 105 parts every 3 minutes.
• Each stamping machine stamps 24 parts every 20 seconds.
Part A
How many parts can all 6 cutting machines cut in 1 minute?
A. 105 parts
B. 140 parts
C. 210 parts
D. 315 parts
Answers
210 pieces
Step-by-step explanation:
First, you need to figure out how many pieces a single machine can cut in a minute, so you need to divide 105 by 3, which gets you 35 pieces per minute.
Next, since we know there are 6 machines, and one machine canncut 35 pieces per minute, we can the figure out how many pieces all 6 cutting machines can cut in 1 minute. You would do this by making an equation such as this:
[tex]35 \times 6 = x[/tex]
The x represents the total number of pieces cut by all 6 machines in one minute.
Next, since we now have an equation, we can go ahead and solve it. We would multiply 35 by 6, which would get us 210 pieces per minute that can be cut by all six machines
Answer: c. 210
Step-by-step explanation:
105 parts divided by 3 minutes equals 35 parts every minute times 6 (number of machines) equals 210 parts are cut every minute at the factor.
