Answer:
15 represents where Jerry is after the elevation dropped 25 meters and then rose 40 meters.
Step-by-step explanation:
It's given that Jerry hiked downhill to a valley where the elevation dropped 25 meters below his starting position. Then, he hiked up to a hill that was 40 meters higher than the valley
Hiked downhill = 25 meters
Hiked up = 40 meters
The given equation is
Here, hiked downhill represented by negative sign and hiked up resents by positive sign.
So, 15 represents that Jerry hiked up 15 meters from his starting position.
(2, the hill was 15 meters higher than the elevation of his starting point)
Answer:
2.
Step-by-step explanation:
The hill was -25 + 40 = 15 meters highe than starting point.

Answer:
0,24 m
Step-by-step explanation:
La table est un rectanble donc l'angle en haut à droite est de 90°.
Tu connais donc un angle et le côté opposé à l'angle et tu cherche le côté adjacent.
On sait que tan(â) = [tex]\frac{Cote oppose}{Cote adjacent}[/tex] donc :
tan(40)= [tex]\frac{1,27}{x}[/tex]
[tex]\frac{1,27}{tan(40)} = x[/tex]
donc x ≈ 1,51 m
Le trou du mileu est à [tex]\frac{2,54}{2}[/tex] soit 1,27m du bord.
Donc elle doit taper à 1,51 - 1,27 = 0,24m du trou du milieu.

Find the measure of each angle indicated.
The measure of the unknown angle in the triangle is 58 degrees.
What is a triangle ?A triangle has three sides and the sum of the angles of a triangle is 180 degrees.
Triangles can be classified base on there angles and length of the sides.
Therefore,
let the length of the unknown angle = x
x + 65° + 57° = 180°
x + 122 = 180
subtract 122 from both sides
x + 122 - 122 = 180 - 122
x = 58 degrees

Identify the number of vertices, edges, and faces of the polyhedron. Use your results to verify Euler's formula.
Answer:
The Last option
Step-by-step explanation:
We see this figure has eight faces, so we already know the answer choice is D, because answer choice D is the only option with 8 faces.
Now let's prove this using Euler's Formula
F = Faces
V = Vertices
E = Edges
We see 12 vertices, 8 faces, and 18 edges. Now plug in the formula.
F + V = E + 2
8 + 12 = 18 + 2

C. 28,000 ft²
D. 26,000 ft²
Answer:

A line passes through the point (-8,5) and has a slope of -3/4 .
Write an equation in slope-intercept form for this line.
Answer:
Step-by-step explanation:
Formula
The basic formula is
y = mx + b
m = the slope
b = the y intercept
What you know so far
y = mx + b.
You know that the slope = -3/4
y = - 3/4 x + b
y intercept
The point is used to find the y intercept.
x = - 8
y = 5
Subtitute these two values into the equation above.
5 = -3/4 * (-8) + b Multiply the factors on the right
5 = 6 + b Subtract 6 from both sides
5 - 6 = b Combine
-1 = b
Answer: y = -(3/4) x - 1
Answer:
[tex]\Longrightarrow:\boxed{\sf{y=-\dfrac{3}{4}x-1}}[/tex]
Step-by-step explanation:
Use the slope-intercept form.
Slope-intercept form:
[tex]\Longrightarrow: \sf{y=mx+b}[/tex]
The m represents the slope.The b represents the y-intercept.X= (-8)
Y= 5
[tex]\sf{5=-\dfrac{3}{4}*(-8)+b}[/tex]
5=6+b
Subtract the sign.
5-6=b
Solve.
Isolate the term of b from one side of the equation.
Subtract the numbers from left to right.
⇒ 5-6=-1
⇒ -1=b
Change the equation.
⇒ b=-1
So, therefore, the y-intercept is -1.
[tex]\Longrightarrow: \boxed{\sf{y=-\dfrac{3}{4}x-1}}[/tex]
Therefore, the correct answer is y=-3/4x-1.I hope this helps! Let me know if you have any questions.

If the number of bacteria in a colony doubles every 336 hours and there is currently a
population of 9,000 bacteria, what will the population be 672 hours from now?
bacteria
The population of bacteria after 672 hours is 36000.
What is unitary method?
The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
According to the given question we have
The number of bacteria double is 336 hours.
And, the current population of bacteria is 9,000.
Therefore,
The population of bacteria after 336 hours = 9,000×2 = 18,000
⇒ the population of bacteria after 672 hours = 18000 × 2 = 36000
Hence, the population of bacteria after 672 hours is 36000.

train station, rode on a train for 14 hours, and then took a bus.
How much time did Jerry spend riding on the bus?
Show your work.
Answer
hours
Answer:
What we know:
39 hours is the total amount of time spent on the trip.14 hours spent with both walking and the train.Our challenge:
To figure out how many __ hours were spent on the bus.Let's set up an equation,
-we'll assume that 'x' are the unknown hours spent on the bus.
The unknown hours spent on the bus plus the hours spent both on walking/and the train will equal a total of 39 hours.
So,
14 + x = 39
Solve for x;
-14 -14
x = 25, the hours Jerry spent riding on the bus is 25 hours.
Answer:
25 hours
Step-by-step explanation:
Given
It took 39 hours in total to get to his grandmother's houseWalking and train transit takes 14 hours togetherSolving
Total time = Time (walking) + Time (train) + Time (bus)39 hours = 14 hours + Time (bus)Time (bus) = 39 - 14 = 25 hoursm/5 = 25

Find the volume of a pyramid with a square base, where the perimeter of the base is 14 m and the height of the pyramid is 8.8 m. Round your answer to the nearest tenth of a cubic meter.
The volume of the pyramid with a square base, where the perimeter of the base is 14 m and the height of the pyramid is 8.8 m is 35.9 m³
How do i determine the volume of the pyramid?First, we shall determine the determine the area of the square base. This is shown below:
Perimeter of square (P) = 14 mArea of the square base (A) = ?P = 4L
14 = 4L
Divide both sides by 4
L = 14 / 4
L = 3.5 m
Now, the area is obtained as follow
A = L²
A = 3.5²
A = 12.25 m²
Finally, we shall determine the volume of the pyramid. Details below:
Area of the square base (A) = 12.25 m²Height of pyramid (h) = 8.8 mVolume of pyramid (V) = ?V = ⅓Ah
V = ⅓ × 12.25 × 8.8
V = 35.9 m³

Solve the right triangle.
Round your answers to the nearest tenth
answer:
A=46°
a=17.983 (tenths- 18, hundredths- 17.98)
b=17.366 (tenths- 17.4, hundredths- 17.37)
explanation:
1. find angle A
it shows that the angle corresponding with the side length of 25 is a right angle, meaning it's 90°. using that information and the angle given to us (44°), we're able to find the missing angle. since all the angles in a triangle always add up to 180°, we can add the two angles together and then subtract that from 180° to find the missing angle.
90°+44°=134°
180°-134°=46°
A=46°
2. find side a
using the law of cosines, we're able to find the length of side a. cosine of an angle equals [tex]\frac{adjacent}{hypotenuse}[/tex]. we'll be using angle B (44°) for our angle. after we plug in the values, we can just solve the equation to find side a.
cosine44°=[tex]\frac{a}{25}[/tex]
(multiply both sides by 25)
25cosine44°=a
a=17.983
3. find side b
finding the length of side b is very similar to how you found side a. you can use the law of cosines again (make sure you use the right side lengths and angles!), but i used the law of sines. the sine of an angle equals [tex]\frac{opposite}{hypotenuse}[/tex]. we're going to be using the same angle for this.
sine44°=[tex]\frac{b}{25}[/tex]
(multiply both sides by 25)
25sine44°=b
b=17.366

Answer:
Area = 32 π in^2
Step-by-step explanation:
Area of the Circle : Area = 2 *π * r^2
diameter = 2 *radius
8 inches = 2 * radius
radius = 8 in/2 = 4 in
radius = 4 in
Area = 2 *π * r^2
Area = 2 *π * (4 in)^2
Area = 2 *π * 16 in^2
