Gnesinka [82]

Answer:

48.49 feet

Step-by-step explanation:

The diagrammatic sketch of the information provided in the question was attached in the image below.

From the image below, the distance between the two kites is denoted by (c) and can be determined by using the cosine angle rule which is expressed as:

c^2 = a^2 + b^2 -2ab cos \ C

where;

a = 110

b = 104

Cos C = 26°

Then;

c^2 = 110^2 + 104^2 -2(110)(104) cos \ 26 \\ \\  c^2 = 12100 + 10816- 22880 ( 0.8988) \\ \\  c^2 = 22916- 20564.544 \\ \\  c^2 = 2351.456 \\ \\  c= \sqrt{2351.456} \\ \\ \mathbf{ c = 48.49 \ feet}

The radius of a circle is 9 times the radius of a smaller circle. The area of the smaller circle is 50 square centimeters. What
scoundrel [369]

Answer:

Let R = radius of big circle

r=radius of small circle

A1=Area of small circle

A2=Area of big circle

R=9r

A1=50cm^2

A1=pi*r*2

A2=pi*R^2

A2=pi*(9r)^2

A2=81*pi*r^2

A2=81*A1

A2=4050cm^2

Hence the big circle has area of 4050cm^2

Frank invests $1,000 in simple interest investment account that pays 8% a year. After a number of years, he withdraws his balanc
elena-s [515]

Answer:

15 years

Step-by-step explanation:

Given data

P=$1,000

R=8%

A= $2200

I= A-P

I=2200-1000

I=$1200

Applying the formula

I=PRT/100

1200=1000*8*T/100

cross multiply

1200*100= 8000T

120000= 8000T

divide both sides by 8000

T=120000/8000

T=15  years

Hence the time is 15 years
