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
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)

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
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.
Match each equation with a diagram:

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

A. 1/12
B. 3/4
C. 11/12
D. 1 1/3
Answer:

A blue spruce grows an average of 6 inches per year and a hemlock grows an average of 4 inches per year.
If a blue spruce is currently 4 feet tall and a hemlock is 6 feet tall , when would you expect the trees to be the same height.
Answer:
It will take 12 years for the trees to be at the same height.
Step-by-step explanation:
Answer:
12 years
Step-by-step explanation:
blue spruce = 0.5 ft/yr & 4 ft tall
Hemlock = 0.33 ft/yr & 6 ft tall
x = number of years
spruce hemlock
(4+0.5x) = (6+0.33x)

In Jaunary your Verizon cell phone bill costs $12 for 80 minutes and in March your bill costs $9 for 60 minutes.
A) Determine whether the rate at which you are being charged for your phone bill is proportional to the amount of minutes being used. Explain.
Both rates are same when you divide them. 80/12= 6.6667 and 60/9= 6.667.
So, 6.6667 is the rate for each minute

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
4 = − 1 1 6
4 4 = − 1 1 6 4
= − 2 9

This is the graph of a __function.
The y-intercept of the graph is the function value y=
The smallest positive x-intercept of the graph is located at x=
The greatest value of y is y=___, and it occurs when x=
For x between x = π and 2π, the function value y ___ 0
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.

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.
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.
