The cost is 47 dollars .
Bas_tet [7]3 years ago

Answer:

$47

Step-by-step explanation:

Create a system of equations where s is the cost of a shirt and t is the cost of a tie:

s + t = 64

s = t + 30

Solve by substitution by substituting (t + 30) into the first equation as s:

s + t = 64

(t + 30) + t = 64

Add like terms and solve for t:

2t + 30 = 64

2t = 34

t = 17

Then, plug in 17 as t into one of the equations to find s:

s = t  + 30

s = 17 + 30

s = 47

So, the cost of the shirt is $47

Ok so this is a difference of 2 perfect squares
1=1^2
49c^2=(7c)^2
to factor you remember
a^2-b^2=(a+b)(a-b) so

1^2-(7c)^2=(1+7c)(1-7c)

Find the arc length for a circle with diameter 10 inches and central angle 60 degrees. Round to the nearest tenth.
UkoKoshka [18]

Answer:

C. 5.2 cm

Step-by-step explanation:

Arc length formula:

s = \dfrac{n}{360^\circ} 2 \pi r

where s = arc length

n = central angle of arc

r = radius of circle

diamter = d = 10 cm

r = d/2 = 10 cm/2 = 5 cm

n = 60 deg

s = \dfrac{n}{360^\circ} 2 \pi r

s = \dfrac{60^\circ}{360^\circ} 2 \times 3.14159 \times 5 ~cm

s = 5.2~cm

Answer: 5.2 cm
