WILL GIVE BRAINLIEST

Mathematics
1 answer:
Montano1993 [528]2 years ago
3 0

Step-by-step explanation:

Use the compound interest formula:

A = P( 1 + r/n)^nt

A is the amount at the end

P is the principal or original amount.

R is annual rate as a decimal (you have to convert)

N is the # of compounding periods in a year (quarterly means 4)

T is time in years

A = 500( 1 + 0.0475/4)^(4×20)

This would be $1285.64 when fully computed.

There is a tall tree in ivas backyard. She thinks it might hit her house if it fell over. She measures that the base of the tree
GrogVix [38]

Answer:

The height of the tree is Greater than 50 feet, so Iva’s house is not safe

Step-by-step explanation:

Find the height of the tree

Let

h ----> the height of the tree

we know that

The tangent of angle of 50 degrees is equal to divide the opposite side to the angle of 50 degrees (height of the tree) by the adjacent side to the angle of 50 degrees (tree’s distance from the house)

so

tan(50°)=h/50

h=(50)tan(50°)=59.6 ft

therefore

The height of the tree is Greater than 50 feet, so Iva’s house is not safe

Step-by-step explanation: First, two halves make a whole, so we simply multiply how many miles he ran in half an hour by 2!

Answer:

There is a group anxiously waiting to start their triathlon. They are in the sand getting ready for the first leg of the race…the swim!  They have roped off a rectangle of the beach that is 200 yards long and 10 yards wide.  The athletes are packed in trying fighting for the front. If we assume that 10 athletes can occupy 25 square feet, how many triathletes are?

10 yds x 200 yds = 2000 sq yds.

2000 x 9 = 18000 sq ft

18000/25 = 720 sections that are 25 sq ft

720 sections x 10 people/section = 7200 triathletes
