Answer:
10.8 cm


Step-by-step explanation:
we know that
1) A square picture with side length 30 cm is scaled by 60% on a photocopier
Remember that
60% =60/100 = .60

so The length of the first copy of the picture is
30(.60) = 18

2) The copy is then scaled by 60% again
so
The length of the second copy of the picture is
18(.60)=10.8 cm

Answer:

y-6=-1/3(x+6)

Step-by-step explanation:

y-y1=m(x-x1)

m=(y2-y1)/(x2-x1)

m=(3-6)/(3-(-6))

m=-3/(3+6)

m=-3/9

simplify

m=-1/3

y-6=-1/3(x-(-6))

y-6=-1/3(x+6)

Two partners agree to invest equal amounts in their business. One will contribute​ $10,000 immediately. The other plans to contr
krek1111 [17]

Answer:

She should contribute $ 8369.38 ( approx )

Step-by-step explanation:

Let P be the amount invested by the other partner,

∵ The amount formula in compound interest,

A=P(1+\frac{r}{n})^{nt}

Where,

r = annual rate,

n = number of compounding periods in a year,

t = number of years,

Here, r = 9% = 0.09, n = 4 ( quarters in a year ), t = 2 years,

Then the amount after 2 years,

A = P(1+\frac{0.09}{4})^{8}

According to the question,

A = $ 10,000,

P(1+\frac{0.09}{4})^{8}= 10000

P(1+0.0225)^8 = 10000

\implies P = \frac{10000}{1.0225^8}\approx \$ 8369.38

the ratio of the measures of the sides of a triangle is 21:8:14. if the perimeter of the triangle is 215 ft, find the length of
Anestetic [448]

Answer:

see explanation

Step-by-step explanation:

the perimeter is the sum of the 3 sides of the triangle

add the parts of the ratio 21 + 8 + 14 = 43

divide the perimeter by 43 to find the value of one part of the ratio

\frac{215}{43} = 5 ft ← 1 part of the ratio, hence

21 parts = 21 × 5 = 105 ft

8 parts = 8 × 5 = 40 ft

14 parts = 14 × 5 = 70 ft

the 3 sides of the triangle are 105 ft, 40 ft and 70 ft
