Answer:
3200
Step-by-step explanation:
Simple interest = [ (Principle x Rate x time) /100 ]
Substitute all values: (800 x 2 x 20)/100 = 3200
Hope this helps
Answer:
1120

Step-by-step explanation:
area = [tex]\pi[/tex][tex]r^{2}[/tex] so it's [tex]\pi[/tex][tex]7^{2}[/tex] = 153.938... [tex]cm^{2}[/tex]
circumference is 2[tex]\pi[/tex]r = 2*[tex]\pi[/tex]*7 = 43.98229 cm
A stop sign is in the shape of an octagon. Find the perimeter if each side is 2a + 1 units
Given,
Side of the octagon = ( 2a + 1 ) units» Perimeter means total length of its boundary.
→ Octagon has 8 sides.
So,
→ Perimeter of Octagon = Length of 8 sides
→ Perimeter of Octagon = 8 ( 2a + 1 ) units
→ Perimeter of Octagon = 16a + 8 units
Therefore,
Perimeter of the octagon is [tex] \bf 16a + 8 [/tex] units.Step-by-step explanation:
Side of the octagon
An octagon has 8 sides. Each side is 2a + 1 units.
8(2a + 1)
= 16a + 8
a ranger is at the top of a 200 foot tall lookout tower. she spots a fire at an angle of depression of 3° from the top of her tower. To the nearest tenth of a foot, how far away is the fire?
Step-by-step explanation:
tan3 = 200/x
x = 200/tan3
The question is incomplete. The right question is:
A ranger spots a fire while on a 200-foot observation tower. The angle of depression from the tower to the fire is 3°. To the nearest tenth of a foot, how far away is the fire from the base of the tower?
The distance between the fire and the base of the tower is 3816.2 feet.
What is the concept of height and distances?Heights and Distances is a trigonometric application-based concept, where we try to form a right-angled triangle of the given conditions, take the angles of elevation and depression and try to find the unknowns.
How do we solve the given question?We are given that a ranger spots a fire while on a 200-foot observation tower. The angle of depression from the tower to the fire is 3°.
We are asked to find the distance between the fire and the base of the tower.
We let the 200-foot observation tower be AB. Let the point of fire be C. Join BC and AC to complete the right-angled triangle ABC, with ∠B = 90°. The ranger from the top of the tower has a 3° angle of depression to the fire. We draw the horizontal line of sight AD. Now the angle of depression can be shown by the ∠DAC = 3°.
We let the distance between the fire and the foot of the tower be x foot.
∠BCA = ∠DAC = 3° (alternate angles).
Also, ∠BAC = 180° - 90° - 3° = 87° (using angle sum property of triangles)
In ΔABC,
tan ∠BAC = BC/AB (tan θ = perpendicular/base)
or, tan 87° = x/200
or, x = 200*tan87° = 200*19.0811 = 3816.22 = 3816.2 (rounding to nearest tenth).
∴ The distance between the fire and the base of the tower is 3816.2 feet.

Which statement about gravity is true?
A. Gravity pulls all objects together, big or small
B. Gravity decreases as mass decreases
C. Gravity decreases as distance increases
D. Gravity pulls only very large objects together
Please help, If I don't get at least a B my parents will kill me.
Answer:
D is false
A is true
B is true
C is true
Step-by-step explanation:
Answer:
I this a multiple choice answer? I found that A B and C are true.
I know this because the article Newtons laws of Universal Gravitation states that "Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are separated from each other, the force of gravitational attraction between them also decreases." This makes C the best answer

A teacher buys 6.25 ounces of a compound for an experiment. The compound costs $4.12 per ounce. The teacher pays with a $50 bill. How much change does the teacher receive?
Answer:
$24.25
Step-by-step explanation:
Given data
We are told that 1 ounce cost $4.12
Hence 6.25 ounces will cost x
cross multiply
x= 6.25*4.12
x=$25.75
This means that the cost of the 6.25 ounces is $25.75
If the teacher pays with a $50 bill, then her change is
=50-25.75
=$24.25
In the coordinate plane below, quadrilateral PQRS is reflected over the x-axis. Which segment is segment QR congruent to?
Answer:
Q'R'
Step-by-step explanation:
Given
Quadrilateral PQRS
Reflected over x-axis
Required
Congruent side to QR
This question has a missing attachment, but can still be solved without the attachment.
When a shape is reflected, the sides and the angles of the shape remain unchanged.
This means that when PQRS is reflected to give P'Q'R'S, the following sides will be congruent.
[tex]PQ = P'Q'[/tex]
[tex]QR = Q'R'[/tex]
[tex]RS = R'S'[/tex]
[tex]SP = S'P'[/tex]
Hence, QR will be congruent to Q'R'

height = 6.92820323028km (you can round if you want to)
Step-by-step explanation:
8km - 4km = 4km (this is for one of the side lengths of the traingle)
a² + b² = c²
4² + b² = 8² (b will be used to represent the height)
16 + b² = 64
b² = 48
b = 6.92820323028km
