Answer:

Answer:

=439.04 ft^2

Step-by-step explanation:

First find the area of the total rectangle

A = l*w

40*16 =640 ft^2

We have 2 semi circles with diameter 16

That equals 1 circle with diameter 16

The radius is d/2 = 16/2 =8

The area of a circle is

A = pi r^2

A = (3.14) (8)^2

  =200.96

Subtract the unshaded area from the total area

640-200.96=439.04

He number of 90° angles formed by the intersections of and the two parallel lines and is .

Answers

Answer:

When you will draw two parallel lines , and a Transversal cutting it

The Transversal may cut the parallel lines in two ways

(a)The Transversal may be perpendicular to two lines

(b) The Transversal may cut the two parallel lines which are not perpendicular.

In both the cases , 8 angles will be formed and sum of all the angles will be 720°.

When you will consider case a , there will be exactly 8 right angles.

When you will consider case b, there will be no angle equal to 90°, but sum of total angle is 720°, which will be equal to 8 right angles.

A line perpendicular to the two parallel lines would create 8 right angles. 

What operation should be performed first in the expression 8 - 2 + 5 x (16 + 66 didved by 2)

Answers

Because of he parenthesis, the operation in it must be performed first.
So (16+66/2) should be performed FIRST.

8 - 2 + 5 x ( 16 + 66 ÷ 2)

Do the ÷ in the bracket:

= 8 - 2 + 5 x ( 16 + 33)

Do the operation in the bracket:

= 8 - 2 + 5 x 49

Do multiplication:

= 8 - 2 + 245

Do subtraction:

= 6 + 245

Do addition:

= 251

A sewing kit includes a spool that holds 24 yards of threadHow many inches of thread does the spool hold (1 yard = 3, 1 foot = 12 inches)

Answers

A sewing kitincludes a spool that holds 864 inches of thread.

Given that,
A sewing kit includes a spool that holds 24 yards of thread, how many inches of thread does the spool hold is to be determined.

What is standard measurement?

All over the world, most things are in use as of commonquantity, so people all over the world agree that they have to follow a common system of measurement and that the commonsystem of measurement is called standardmeasurement.

here,
1 yard = 3, 1 foot = 12 inches
So,
24 yard = 24 [3] feets
24 [3] feet = 24 [3] [12] inches = 864 inches

Thus, A sewing kit includes a spool that holds 864 inches of thread.

Answer:

864 inches

Step-by-step explanation:

12*3=36

36*24=864

Two cell phone companies have different rate plans. Runfast has monthly charges $25 plus $10 per gig of data. B A &D’s monthly charge is $18 plus 15 per gig of data. Your task is to determine under what circumstances each company has the better pricing. You will derive and solve a set of equations, graph those equations, and evaluate the meanings for these events. Don’t worry; I have a series of questions to guide you through the process. Good luck!Determine the equation for the monthly charges for Runfast and BA&D.

Runfast= $35 per month

BA&D= $33 per month

Answers

Given:
Runfast = 25 + 10g
BA&D = 18 + 15g

Runfast = 35 per month
35 = 25 + 10g
35 - 25 = 10g
10 = 10g
10/10 = g
1 = g

BA&D = 33 per month
33 = 18 + 15g
33 - 18 = 15g
15 = 15g
15/15 = g
1 = g

If g = 2;
Runfast = 25 + 10(2) = 25 + 20 = 45
BA&D = 18 + 15(2) = 18 + 30 = 48

Based on my computation, if the gig of data is only equivalent to 1g then BA&D is cheaper. However, if 2gig or above is used, then Runfast is cheaper.
