Answer:
Length of armoured vehicle: 19.8 ft
Step-by-step explanation:
1 is to 3.3 in as 72 is to x:
1 72
-------- = --------
3.3 x
This yields x = 237.6 (inches), which corresponds to 237.6/12 (feet):

Hppe it hels, Let me know if you have any questions !
what is the approximate value of x when f(x) = g(x)
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?

Victoria is at an elevation of 150 feet. She hikes down to an elevation of 120 feet in 40 minutes. Then she hikes down to an elevation of 100 feet in 30 minutes.
Answer:
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.

Laura multiplied 27,890 by a fraction with a numerator of 12. The product
was less than 27,890. Which of the following statements is true about the
denominator of Laura's fraction?
Answer:
I don't see any optional answers, but the denominator must be greater than 12.
Step-by-step explanation:
27,890*(12/X) < 27,890
Therefore (12/X) < 1

The price of a loaf of a particular type of bread increased from $3.70 to $5.59 from 2011 to 2021. What was the percent increase in the price of the loaf of bread over those 10 years? Round your answer to the nearest tenth of a percent.
The price of the loaf of bread over the 10 years was_____%(round to the nearest tenth of a percent.)
Answer:
51.1% to the nearest tenth.
Step-by-step explanation:
Increase = 5.59 - 3.70 = $1.89.
% increase = (1.89/3.70) + 100

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

What is the spatial relationship between a rectangle and a parallelogram?
Answer:
a rectangle is a parallelogram as the parallogram is made up of 2 triangles and a smaller rectangle. When the rectangle is divided into 2 triangles and another small rectangle, and is then being put together with the triangles on each side, it will be a parallelogram.
Step-by-step explanation:
Explanation:
A rectangle has the following properties:
Has 4 sidesHas 4 right anglesOpposite sides lengths are equal.Diagonals of rectangle are equal.Opposite sides are parallel.A parallelogram has the following properties:
Has 4 sidesOpposite angles are equal.Opposite sides are equal.Opposite sides are parallel.The similiarities between a rectangle and a parallelgram:
Has 4 sidesOpposite sides are parallel.Opposite sides are equal.Opposite sides lengths are equal.The difference between a rectangle and a parallelogram:
The main difference between a rectangle and a parallelogram is that a rectangle has four right angles while a parallelogram does not have four right angles.
What are the measures of Angles a, b, and c? Show your work and explain your answers.
IM NOT LOOKING FOR ANY JOKES OR STUFF, JUST STRAIGHT UP SHOW THE WORK AND THE ANSWER PLEASE. (30 PNTS IF ANSWERED CORRECTLY) NEED HELP ASAP!
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.

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

Consider the following incomplete deposit ticket: a deposit ticket. the amounts deposited were 491 dollars and 60 cents and 157 dollars and 68 cents. 68 dollars and 44 cents was taken out as cash. the total on the ticket is 686 dollars and 4 cents. what was the value of the third check tony deposited? a. $617.60 b. $105.20 c. $31.28 d. $36.76
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
How to get the resultant deposited amount?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:
Deposited amounts were: First check: $491.60 Second check: $157.68 Third check: $x (to find)Deducted amount was: $68.44Net deposite = $686.04Thus, 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

Adam wishes to have $19,000 available in 18 years to purchase a new car for his son as a gift for his high school graduation. To accomplish this goal, how much should Adam invest now in a CD that pays 1.92% interest compounded semiannually? Adam should invest $ NOW. (Round to the nearest cent as needed.)
The amount of money Adam should save now in order to accomplish his goal is $13,470.30.
How much should Adam save now?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
