a man borrows money 800 for 2 years at a simple interest rate 20%. what is the total amount that must be repaid?

Answer:

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

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'

Given,

» 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,

Step-by-step explanation:

Side of the octagon

An octagon has 8 sides. Each side is 2a + 1 units.

8(2a + 1)

= 16a + 8

Answer:

7

Step-by-step explanation:

(a+b)/2 x h

42 = (8+4)/2 x h

42 = 6h

h = 7

Answer:

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

Answer:

as there are no choices I will explain  k is 2 or bigger

Step-by-step explanation:

≥ means the number to the left is bigger or the same as the other so that means k is 2 or bigger

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.

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.

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.

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

can you make the question more clear please

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

It will form scalene triangle

because it has different measures of sides

that is no equal side
