We know the following:

so the segment EF is equal to

and here we can do a trick :)

[tex]EF=(EG+GO)+GO+(OF+OG)-2GO\\\\[/tex]

you see it's the same

[tex]EF=EO-GO+FG\\\\[/tex]

now we plug the values given

Answer:

a) T(t) = -13 +0.5t

b) D(t) = -4 -0.25t

c) 12 seconds

d) 7 feet

Step-by-step explanation:

a) The turtle starts at -13 feet and increases its elevation relative to the water's surface by 0.5 ft/second. After t seconds, the turtle will be 0.5t feet closer to the surface, so its depth will be ...

T(t) = -13 +0.5t

b) The diver starts at -4 feet and decreases their elevation relative to the water's surface by 0.35 ft/second. After t seconds, the diver will be 0.25t lower than the initial position, so their depth will be ...

D(t) = -4 -0.25t

c) The diver and turtle will be at the same depth when ...

T(t) = D(t)

-13 +0.50t = -4 -0.25t

0.75t = 9 . . . . . . . . . . . . add 13+0.25t

t = 12 . . . . . . . . . . . . . . . divide by 0.75

The diver and turtle will be at the same depth after 12 seconds.

d) That depth will be ...

T(12) = -13 +0.5(12) = -13 +6 = -7

The diver and turtle meet at a depth of 7 feet.

A triangle has one side that measures x, and the other two sides each measure 4 inches less than x. The perimeter is 19 inches.

What is the measure of x?

5
3
9
2

Answers

Answer:

x=9

Step-by-step explanation:

x + x - 4 + x - 4 = 19

3x - 8 = 19

3x = 19 + 8

3x = 27

x = 9

Answer: x=9

Step-by-step explanation:

There are three sides 2 that are x-4 and 1 that is x. The equation would be

x+2(x-4)= 19 so you would simplify to get

X+2x-8=19 then 3x=27 then divide by three to get x=9

The rate to rent a truck for a day is a one-time fee of $35 and $0.20 per mile.

Write an expression to model this situation.
How far could you travel if you drove 40 miles?

Answers

Answer: y= $0.20x + $35 or y= $0.20 * 40 + $35 (Depending on what you mean)

Step-by-step explanation:

The equation for these types of problems is y = mx + b.

M would be $0.20, because that is the value that can repeat, based on x. For example, if this was 2 dollars per mile (m) for 3 miles, (x) than y, the total amount for mx would amount to 6 dollars.

Now, 35$ Is a one time fee (b), so you can add that separately to $0.20x.

If you plug everything in, you would get y= $0.20x + $35.

I am not very sure about what you mean by “ How far you could you travel if you drove 40 miles”, but if you mean how much would you pay to drive 40 miles, I can help there.

Now that we know x would be the amount of miles, we can plug that into the equation.

You would get y= $0.20 * 40 + $35.

Sorry, I’m not that good at explaining, but I hoped this helped!

y= .20x + 35

It would cost $43 to travel 40 miles
