Answer:

20in²

Step-by-step explanation:

The area of a triangle is calculated using the formula A = bh/2

"A" means area.

"b" is for the base.

"h" is for the height.

It does not matter which is the base and which is the height, as long as they are perpendicular (at 90°) to each other.

5in can be the height.

8in can be the base.

Put the base and height measurements into the formula.

A = bh/2

A = (8in)(5in)/2    Multiply the measurements and the units.

A = (40in²)/2   Divide by 2

A = 20in²       Area of the triangle

When you multiply units, in X in becomes in².

"in" has the exponents 1. When you multiply two "in" with exponent 1, you add the exponents. 1 + 2 = 2.

in¹ X in¹ = in¹⁺¹ = in²

Answer:

20 square inches.

Step-by-step explanation:

Finding the area of a triangle is relatively easy. Solve like a regular square/rectangle with the equation l*w=a. Plug in the values and you get 5*8=a. 8*5=40. ALTHOUGH with triangles you must half the answer because a triangle is half of a rectangle/square. So you would divide 40 by 2 and you get 20.

Sphinxa [80]

Answer:

All payments will be made at the end of the year by using the present value of inflows

Step-by-step explanation:

Present Value Of Inflows = Cash Inflow × Present Value Of Discounting Factor (Rate%,Time Period)

Present Value Of Inflows = 15000/1.037 + 25000/1.037^{2} + 40000/1.037^{3} + 60000/1.037^{4}

Present Value Of Inflows = 125466.3

Urgent please help !!!!!

If all 3 angles of a Triangle MUST equal 180°, then we know that we use the equation (for this triangle) to find the angle measurements as (180-90)/2 which means we are dividing 90/2 which is 45° for each angle. But these angles are different measures, so we have to guess upon this and say that YOUR ANSWER IS D

Do not multiply by pi. Just use the whole number and do not try to include pi in the
IrinaK [193]

Answer:

Surface area = 1808.64in² and volume is 7234.56in³

Step-by-step explanation:

The figure above is a sphere, and it has a diameter of 24in

Radius = ?

Radius = diameter / 2

R = 24 / 2

R = 12in

Surface area of of sphere = 4πr²

Volume of a sphere = 4/3 πr³

π = 3.14

1. Surface area = 4 * 3.14 * 12²

Surface area = 4 * 3.14 * 144

Surface area = 1808.64in²

2. Volume of the sphere = 4/3πr³

Volume = 4/3 * 3.14 * 12³

Volume = 4/3 * 3.14 * 1728

Volume = 7234.56in³

The surface area of the sphere is 1808.64in² and the volume is 7234

56in³

(-w-6)/(w^2+4w-12), how do i write this into simplest form?
PIT_PIT [208]
First factorise the top = -(w+6)
The first factorise the bottom: (w^2 + 4w -12) = (w+6) (w-2)
Therefore the two (w+6) cancels out and you are left with -1 / w-2

The difference between the measures of two supplementary angles is 92. Find the measure of both angles
Sholpan [36]

supplementary angles add up to 180 degrees

x + y = 180

x - y = 92

---------------add

2x = 272

x = 272/2

x = 136 <=== this is one angle

x + y = 180

136 + y = 180

y = 180 - 136

y = 44 <=== this is ur other angle
