Meghan earns $20 for every 5 bracelets she makes. How many bracelets must she make to earn $140?

2 answers:

8 0

So this is a two step equation.
The first step would be to find out how many times 20 goes into 140.
140/20=8
So if she makes 5 bracelets for every 20 dollars she makes, and she made 20 dollars 8 time. She would’ve made 5 bracelets, 8 times.
So take 5 bracelets and multiply it by 8.
She needs to make 40 bracelets. :)

find the area of a circke with a radius of 9 mm. round to the nearest tenth. use 3.15 or 22/7 for Pi.

GREYUIT [131]

Answer:

254.3 mm^2

Step-by-step explanation:

Area of a circle: A = π*r^2

π (pi) = 3.14

r (radius) = 9 mm

Substitute 3.14 for pi and 9 for radius:

A = π*r^2

A = 3.14*9^2

A = 3.14*81

A = 254.34 mm^2

Round to the nearest tenth:

254.34 ==> 254.3

Therefore, our final answer is 254.3 mm^2

Hope this helps!

What is the 4th term in a geometric sequence for which a1=15 and r=1/3

Hitman42 [59]

Geometric goes liket his
$a_n=a_1(r)^{n-1}$
given
a1=15
r=1/3
find a4 or 4th term

$a_4=15( \frac{1}{3} )^{4-1}$
$a_4=15( \frac{1}{3} )^{3}$
$a_4=15 (\frac{1}{27})$
$a_4=\frac{15}{27}$
$a_4=\frac{5}{9}$
4th term is 5/9
