You found yourself lost in a forest. Give an account of your experience and how you found your way out
Answer:
Step-by-step explanation:
This actually happened to me. I was walking out of a national forest and came up to a stream that I had not crossed. I got my bearings confused and realized I was lost. I knew that if I went Northwest it would be about a 30 mile hike out in heavy woods, with obvious other streams to cross. In the Southeast direction, it would only be about 5 miles.
The sun was out but mostly overhead and no help with directions.
I couldn't wait until the sun went farther West to get my directions. It was a warm Winter day but I wasn't dressed to be there after dark when the temperature fell, even if I did go in the correct direction.
I stuck a stick in the ground and made a mark in the dirt at the end of it's shadow. I sat down for about 15 minutes, then made a new mark in the dirt at the end of the sticks shadow again. I drew a line in the dirt to connect the two marks. This line ran close to the East/West direction, the first mark being the West direction.
I made it out about 5 PM just as the sun was disappearing through the trees.
in science class vicky did an experiment with an unknown soild. she started with 21 grams of the solid. During the experiment , the change in the mass of the solid was -4 grams. what was the final mass of the solid ?
Answer:
17 grams
Step-by-step explanation:
21grams-4=17grams
Answer:
17 grams
Step-by-step explanation:
Since the starting mass was 21 and the change was -4, you would do 21-4, which gives you 17 grams (or the final mass).
Solve the equation.

There are 107 coins in a jar, all dimes and nickels. The coins are worth $6.70. How many of each kind of
coin is in the jar?
d = number of dimes
n = number of nickels
The jar contains a total of 107 coins, so
d + n = 107
Each dime is worth $0.10 and each nickel is worth $0.05, and the jar contains a total value of $6.70, so
0.10d + 0.05n = 6.70
Multiply both sides of the second equation by 100 to eliminate the decimal points:
10d + 5n = 670
Multiply both sides of the first equation by -5:
-5d - 5n = -535
Add the corresponding sides of these two equations to eliminate n and solve for d :
(10d + 5n) + (-5d - 5n) = 670 + (-535)
(10 - 5)d + (5 - 5)n = 670 - 535
5d = 135
d = 135/5 = 27
Then
n = 107 - d = 80
so the jar contains 27 dimes and 80 nickels.

Cole is 53 4/5 inches tall. Sheila is 1 1/6 inches taller than Cole and Jane is 1 1/3 inches taller than Sheila. How tall is Jane?
Answer:
54 3/10 inches tall
Step-by-step explanation:
1 1/6 + 1 1/3 = 2 1/2
53 4/5 + 2 1/2 = 54 3/10
The height of Sheila is 62 ²³/₃₀ inches. Then the height of Jane will be 83 ³¹/₄₅ inches.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
Cole is 53 ⁴/₅ inches tall. Sheila is 1 ¹/₆ inches taller than Cole. Then the height of Sheila is calculated as,
⇒ (53 ⁴/₅) × (1 ¹/₆)
⇒ 62 ²³/₃₀
Jane is 1 ¹/₃ inches taller than Sheila. Then the height of Jane is calculated as,
⇒ (62 ²³/₃₀) × (1 ¹/₃)
⇒ 83 ³¹/₄₅ inches
The height of Sheila is 62 ²³/₃₀ inches. Then the height of Jane will be 83 ³¹/₄₅ inches.

Answer:
A = 8x³ +4x² -4x
Step-by-step explanation:
Put the given values into the area formula and simplify.
[tex]A=\dfrac{1}{2}h(b_1+b_2)\\\\A=\dfrac{1}{2}(4x)((x^2+2)+(3x^2+2x-4))\\\\A=(2x)(4x^2+2x-2)\\\\\boxed{A=8x^3+4x^2-4x}[/tex]
A ball is thrown upward from a height of 15 feet with an initial upward velocity of 5 feet per second. Use the formula b(t)= -16t2 + 5t + 15 to find the time it takes for the ball to reach the maximum height of the ball. Round to the nearest tenth.
Answer:
Time taken by the ball to reach the maximum height = 5/32 seconds
Step-by-step explanation:
To find the time at which maximum height is reached , we will differentiate the given equation with respect to t
[tex]\frac{db_{(t)}}{dt} = -32t + 5 = 0\\t = \frac{5}{32} \\[/tex]
Substituting this value of t in formula of b(t), we get
[tex]-16 * (\frac{5}{32})^2 + 5 * \frac{5}{32} + 15 \\= 15.390[/tex]

answer this question and show work or have an explanation.
Answer:
70
Step-by-step explanation: Triangle angle sum theorem states the interior angles of a triangle sum to 180 degrees. We know one angle is 40 degrees and the two remaining angles are equal in measure.
Since angle J and angle L are equal in measure we can substitute 2x for angles J and L into the equation.
40 + 2x = 180. Subtract 40 from both sides.
2x = 140. Divide both sides by 2.
X = 70
find the surface area and volume of a cube with the following dimensions: length 4cm, width 4cm, height 4cm
Answer:
Surface area is 96cm^2, volume is 64 cm^3.
Step-by-step explanation:
Surface area = area of top and bottom + area of left and right + area of front and back.
area of top or bottom = 4×4=16cm^2
area of left or right = 4×4= 16cm^2
area of front or back = 4×4=16cm^2
total surface area = 2(16) + 2(16) + 2(16) = 96cm^2
volume of a cube = length × width × height = 4×4×4 r 64 cm^3.
What is the area of this shape?
A. 42 cm squared
