a) 4.71ft

b) 3.53ft^2

Step-by-step explanation:

Perimeter is 1/2 the circumference

1/2 Circumference = 2*pi*radius

Radius = 1/2 Diameter

Radius = 3/2 = 1.5ft

Circumference = 2*pi*1.5ft = 9.42

1/2 Circumference = 4.71

4.71ft is the perimeter.

The area is 1/2 that of a full circle

A = pi*r^2

A = 3.14*1.5*1.5

A = 7.065ft^2

1/2 A = 3.53ft^2

Zinaida [17]

Answer:

Surface Area = 86 cm^2

Step-by-step explanation:

Given:

Triangle,

b = 8 cm

h = 9 cm

Rectangle,

l = 10 cm

w = 5 cm

To Find:

Surface Area = ?

Solution:

Surface Area = b x h /2 + l x w

Surface Area = 8 x 9 / 2 + 10 x 5

Surface Area = 4 x 9 + 50

Surface Area = 36 + 50

Therefore, Surface Area = 86 cm^2

What is the math answer
never [62]

Answer:

16

Step-by-step explanation:

The perpendicular diameter to the chord divides it into two congruent parts.

Since

  • VU⊥XS,
  • XT=3b-1,
  • TS=b+5,

we have that XT=TS.

Hence,

3b-1=b+5,

3b-b=5+1,

2b=6,

b=3.

So,

XT=3·3-1=9-1=8

TS=3+5=8

and

XS=XT+TS=8+8=16.

I will mark brainliest, please help !!
Elena L [17]

Answer:

x = 5/(a-b+3)

Step-by-step explanation:

ax+3x=bx+5

Collect all the terms that has x:

ax-bx+3x = 5 (Subtracting bx both sides)

Take out the x!

x(a-b+3) =5

Divide (a-b+3) both sides to solve for x

x = 5/(a-b+3)

Hope this helps!

Would really appreicate the brainliest!
