Tony deposited three checks as given in deposite ticket. The amount of the third check that Tony deposited is given by: Option B: $105.20

Resultant deposited amount = Deposited amount - The amount deducted.

We subtract the amount deducted from the amount deposited to get the resultant deposite amount that will go in bank.

Well, it might be that we deduced more than what we deposite, in that case net deposite will come as negative, indicating that there is deduction instead of deposite.

The missing image of the deposite ticket is attached below.

From that image, we can see that:

Thus, the net deposited amount is:

Net deposite = deposited amounts - deduced amounts

686.04 = 491.6 + 157.68 + x - 68.44 (all in dollars)

[tex]686.04 = x+ 491.6 + 157.68 - 68.44\\686.04 = x + 580.84\\\\\text{Subtracting 580.04 from both the sides} \\\\686.04 - 580.84 = x\\x = 105.20 \: \rm dollars[/tex]

Net deposite = 105.20 (in dollars).

Thus, the amount of the third check that Tony deposited is given by: Option B: $105.20

Answer:

The answer is 25

Step-by-step explanation:

Answer:

A. 120 ft

B. 119

C. 2100 ft

Step-by-step explanation:

A. (Slipt the shape into 2 parts so it will be simpler)

For the triangle : 1/2 (4x12)

And for the rectangle : 12x8

1/2 (4x12) = 24

12 x 8 = 96

24 + 96 = 120 ft

_________________________________

B. (this time we can split it into 3 parts)

Longer rectangle : 12x6

Short rectangle : 5x5

Triangle : 1/2 (4x11)

LR : 12x6 = 72

SR : 25

T : 1/2 44 = 22

72+25+22 = 119

______________________________________

C. (Like the first one, we can split it into 2 parts)

Rectangle : 50x30

Triangle : 1/2 40x30

R : 1500

T : 1/2 1200 = 600

1500 + 600 = 2100

Answer:

Convert these ratios into fractions and then into their actual values.

(This is just one way of solving this, there are other plentiful ways you could use to solve this.)

2 : 9

Will become

2/9

Which will result in

0.222...

3 : 18

Will become

3/18

Which will result in

0.1666...

1 : 3

Will become

1/3

Which will result in

0.333...

Now, compare these numbers:-

0.222..., 0.1666..., and 0.333...

And out of these three numbers, 0.333... is by far the greatest number out of all of these ratios.

Therefore, the ratio 1:3 is the largest ratio.

Answer: First portion is greater than second portion.

Step-by-step explanation:

Time taken to hiked down a trail = 10 minutes

Change in elevation = (-) 170 feet

Speed is given by

\begin{gathered}Speed=\frac{Distance}{Time}\\\\Speed=\frac{170}{10}\\\\Speed=17\text{ feet per minute}\end{gathered}

Speed=

Time

Distance

Speed=

10

170

Speed=17 feet per minute

Similarly,

Time taken to hiked down a trail = 20 minutes

Change in elevation = (-)220 feet

Speed is given by

Speed=\frac{Distance}{Time}Speed=

Time

Distance

\begin{gathered}Speed=\frac{220}{20}\\\\Speed=11\text{ feet per minutes}\end{gathered}

Speed=

20

220

Speed=11 feet per minutes

So, we can see that first portion of the hike where he hiked down a trail at a steady rate for 10 minutes and her change in elevation was (-) 170 feet, was her rate of change in elevation greater.

As 17 feet per minutes is greater than 11 feet per minutes.

The amount of money Adam should save now in order to accomplish his goal is $13,470.30.

In order to determine the amount Adam should save now, the present valaue of $19,000 has to be determined. Present value is the sum of discounted cash flows.

Present value = future value / (1 + interest)^time

Interest = 1.92/2 = 0.96%

Time = 18 x 2 = 36

$19,000 / (1.0096^36) = $13,470.30

Answer:

a= 30
b= 60 (pretty sure)
c=105

Step-by-step explanation:

a is a vertical angle to 30, so that means it is also equal to 30.

To find b, since it's on a straight line, you can add up the angles in the triangle and solve for b.

30+90=120

120+b=180

b=60

To find c, you subtract 75 from 180 since it's also a straight line equal to 180 degrees.

Answer:

34)  5 questions

35)  8 questions

36)  9 questions

37)  10 questions

Step-by-step explanation:

We could create an exponential function for this scenario, but it is quicker and easier to simply list the potential scores.

We are told that the initial score is 1.

We are told that the the score doubles each time.

Therefore, the scores in sequence are:  
1, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024 ... etc.

34)  16 is the 5th term in the sequence, so 5 questions

35)  128 is the 8th term in the sequence, so 8 questions

36)  256 is the 9th term in the sequence, so 9 questions

37)  512 is the 10th term in the sequence, so 10 questions

Answer:

I'm a little confused by this question:

Lines and things that are linear are relatively boring in mathematics. What if my function f(x) = g'(x). I’m going to ask the same question in a different way.

What is an approximate value of g'(1.1)?

So I know L(x)=f(a)+f′(a)(x−a)

If I substitute items in, I get g′(x)+g′′(x)(x−x).

Since x−x=0 I always am going to end up with L(x)=g′(x)

I don't think this can be the right answer since I know the whole point is to use the 2nd derivative, but if you get 0 for (x−a), then the whole part ends up being 0. What am I missing here?

I'm completely lost here because these are the followup question after the one above:

Now things are interesting. Suppose g(1) = 0 and g'(1) = 1.

Use linear approximation to approximate the value of g(1.1). The answer to #2 and #3 gives us a slope of a tangent line and a value of a function, which we can use.

Use your previous answers to approximate the value of g(1.2). Somehow, this second derivative has caused an adjustment to our approximation.

What did using the second derivative do to the approximation?

Do you believe the approximation is better or worse than our original?
