Answer:
124.1 m
Step-by-step explanation:
Given that:
Depth of mammoth cave = - 124.1 meters
To travel to the bottom of the cave, hence, the hiker is at the maximum depth.
Since the depth of the cave is - 124.1 m and the hiker has traveled down tonthe bottom and hence covered the total depth. Then thebhiker must have descended by the same value corresponding to the depthnifnthe cave = 124.1 meters
A wind blowing in the direction 0o causes an airplane to drift up 15o from its' original heading of 90o. The ground speed is 336km/hr. Find the airspeed of the plane
Answer:
324.6 km/hr
Step-by-step explanation:
Since the plane drifts up 15° from its original heading of 90°, it is at a bearing of 90° - 15° = 75°.
Now, since its ground speed is 336 km/hr, its air speed, v is the horizontal component of its ground speed since the wind is blowing in the 0° direction. So, v = (336 km/hr)sin75°
= 324.55 km/hr
≅ 324.6 km/hr

How to calculate 12 divided by 4
Long Division
Here we will show you step-by-step with detailed explanation how to calculate 12 divided by 4 using long division.
Before you continue, note that in the problem 12 divided by 4, the numbers are defined as follows:
12 = dividend
4 = divisor
Step 1:
Start by setting it up with the divisor 4 on the left side and the dividend 12 on the right side like this:
4 ⟌ 1 2
Step 2:
The divisor (4) goes into the first digit of the dividend (1), 0 time(s). Therefore, put 0 on top:
0
4 ⟌ 1 2
Step 3:
Multiply the divisor by the result in the previous step (4 x 0 = 0) and write that answer below the dividend.
0
4 ⟌ 1 2
0
Step 4:
Subtract the result in the previous step from the first digit of the dividend (1 - 0 = 1) and write the answer below.
0
4 ⟌ 1 2
- 0
1
Step 5:
Move down the 2nd digit of the dividend (2) like this:
0
4 ⟌ 1 2
- 0
1 2
Step 6:
The divisor (4) goes into the bottom number (12), 3 time(s). Therefore, put 3 on top:
0 3
4 ⟌ 1 2
- 0
1 2
Step 7:
Multiply the divisor by the result in the previous step (4 x 3 = 12) and write that answer at the bottom:
0 3
4 ⟌ 1 2
- 0
1 2
1 2
Step 8:
Subtract the result in the previous step from the number written above it. (12 - 12 = 0) and write the answer at the bottom.
0 3
4 ⟌ 1 2
- 0
1 2
- 1 2

Jamie puts an initial $900 into a savings account. The account has a 7% annual compound interest rate. What is the function that best represents Jamie's account and how much does he have in savings after 5 years? Round your answer to the nearest dollar.
Hint: Use the formula, f(x) = P(1 + r)x
A. f(x) = 900(1.7)x, $1,081
B. f(x) = 900(1.07)x, $1,262
C. f(x) = 900(1.07)x, $1,081
D. f(x) = 900(0.07)x, $1,262
Answer:
D. f(x)=900(0.07)^x.1,262
Step-by-step explanation:
You would have to use the P(1+r)^x
P= starting amount
R= rate of change or the percentage changed into a decimal
x= time
So it would be, 900(1+0.07)^5
calculating that you would get 1,262.3. but approximately it's 1,262.

A patch of farmland is currently worth $78,125. The expected increase in its market value can be modeled by the function below, where tis the
time in years.
P(t) = 78,125 0.025:
How many years will it take for the farmland's market value to reach $125,000?

Answer: t = 18.8 years
Step-by-step explanation: The modeled function is an exponential function:
[tex]P(t)=78,125e^{0.025t}[/tex]
which is farmland worth along time.
To determine when the farmland will be worth $125,000:
[tex]125,000=78,125e^{0.025t}[/tex]
[tex]e^{0.025t}=\frac{125,000}{78,125}[/tex]
[tex]e^{0.025t}=1.6[/tex]
Apply natural logarithm:
[tex]ln(e^{0.025t})=ln(1.6)[/tex]
And then, power rule:
[tex]0.025t=ln(1.6)[/tex]
[tex]t=\frac{ln(1.6)}{0.025}[/tex]
t ≈ [tex]\frac{0.47}{0.025}[/tex]
t ≈ 18.8
After 18.8 years, the farmland will reach market value of $125,000.

What is the slope of a line that passes through the origin and the point (-2,1)?
Answer:
The slope would be -1/2.
Step-by-step explanation:
Since, the midpoint of the segment joining the points P (0, -4) and B (8, 0),
= ( 4, -2 ),
Now, the slope of the line passes through the origin and the point ( 4, -2) is,
= -1/2

55) A shirt that usually costs $30 is on sale for $20. Find the percent of
the discount.
Find the amount of the discount and divide by the original price:
30-20 = 10
10/30 = 0. 333
Multiply by 100 for percent:
0.333 x 100 = 33.3333%
Round the answer as needed.
Answer:
Percentage of Discount :---

The length of a rectangle is one more than twice its width. If its perimeter is 20 inches, what is its length and width?
Answer:
Let length be L
Width be W
L=1+2W
Perimeter(p) of rectangle is
P=2L+2W
But L = 1+ 2W and p= 20
:. 20 =2(1+2W) +2W
20=2+4W+2W
18=6W
Divide both sides by 6
W =3
2W+1=L
6+1=L
L=7
Hence, length and width are 7in and 3in respectively

PLEASE HELP ITS DUE IN 20 MIN !
If your cost is $8.00 and you wish to markup that price by 40%, 80% + 40% = 120%. Divide the $8.00 cost by 120% and get the retail price of $15.00. Therefore, the markup amount is $7.00 ($15.00 - $8.00 = $7.00) and the selling price is $15.

Answer:
1/6 lbs
Step-by-step explanation:
2 1 1
- X - = -
3 4 6
Answer: She ate 5/12 of the turkey.
Step-by-step explanation:
First, find a common denominator by multiplying each fraction by the denominator of the other. By doing this, you should get 8/12, and 3/12.
Next, subtract them!
ex: 2/3= 8/12
1/4=3/12
8/12-3/12=5/12

[tex]\huge\boxed{\sf x =\frac{7}{2} , y = -3}[/tex]
Step-by-step explanation:
2x + 4y = -4 ------------------------(1)
3x + 5y = -3 ------------------------(2)
Multiply Eq. (1) by 3
3(2x + 4y) = -4 * 3
6x + 12y = -12 ---------------------(3)
Multiply Eq. (2) by 2
2(3x + 5y) = -3 * 2
6x + 10y = -6 ---------------------(4)
Subtract Eq. (4) from (3)
6x + 12y - ( 6x + 10y ) = -12 - (-6)
6x + 12y - 6x - 10y = -12 + 6
12y - 10y = -6
2y = -6
Divide 2 to both sides
y = -6 / 2
y = -3
Put y = -3 in Eq. (1)
2x + 4(-3) = -5
2x - 12 = -5
Add 12 to both sides
2x = -5 + 12
2x = 7
Divide 2 to both sides
x = 7 / 2
So,
x = 7 / 2 , y = -3

4×49-84-3
112-3
109
Answer: Your correct and final answer should be 109.
Step-by-step explanation:
All you need to do solve this problem is substitute for X using 7. {After you you plug just use PEMDAS and solve from left to right or use a calculator}
4(7)^2 -12(7) -3
4×49 -84 -3
112-3 = 109

Answer:
The answer is D, E, F or it is also D to F
Step-by-step explanation:
9514 1404 393
Answer:
A and B
Step-by-step explanation:
Speed is the change in distance divided by the change in time. That is, it is the slope of the distance vs. time curve. A steeper slope corresponds to a greater speed.
Between A and B, the slope is (30-0)/(1-0) meters/time-unit = 30 m/u.
Between B and C, the slope is (30-10)/(4-1) = 20/3 = 6 2/3 m/u.
Between C and D, the slope is 0.
Between D and F, the slope is (50-10)/(10-6) = 40/4 = 10 m/u.
The greatest slope is between A and B.
The object has the greatest speed between points A and B.
Jim is mailing packages. Each small package costs him $3.20 to send. Each large costs him $4.70. How much will it cost him to send 1 small package and 4 large packages?
Answer:
$3.20 for the small and $4.70 for the large packages.
Step-by-step explanation:
multiply 3.20 by 1 since that is the price of mailing a small package and you want to mail 1.
multiply 4.70 by 4 since that is the price of a large one and you want to mail 4.
3.20 x 1 =3.20
4.70 x 4=18.80
