Answer: The area is 13 $\pi$ ft^2 or 40.84 ft^2

Step-by-step explanation:

First find the area of the square and subtract it from the area of the circle.

The area of a square is one of the side length squared.

A= 6^2

A = 36

Now find the area of the whole circle.As it indicates that the diameter is 14ft and to find the area of a circle,we need square the radius and multiply it by pi.

Since the diameter is 14 divide it by 2 to find the radius. 14/2 = 7

A= 7^2* $\pi$

A = 49 $\pi$ We will leave the area in terms of pi.

49 $\pi$ - 36 = 13 $\pi$

Answer:

Step-by-step explanation:

Signals during a multiplication of two numbers:

They have the same signal: The multiplication is positive.

They have different signals: The multiplication is negative.

3 times (-8) times (-2)

First 3*(-8):

Different signals, so negative. 3*8 = 24. So the answer is -24.

Then:

3*(-8)*(-2) = (-24)*(-2)

Same signal, so positive. 24*2 = 48. The answer is 48.

Determine whether the equation has no solution, one solution, or infinitely many solutions. 7(12 – 2 x ) = 4(3 – 3 x )

Alex777 [14]

Answer: The equation has one solution

Step-by-step explanation: First , open the brackets

7( 12 - 2x ) = 4 (3 - 3x )

84 - 14x = 12 - 12x

collect the like terms

84 - 12 = - 12x + 14x

72 = 2x

Therefore divide through by 2

x = 72/2

x = 36

Therefore, the equation has only one solution

The 3 stages representing the hierarchy of fluency progression including Automaticity, are embedded into which strand of the B.E

Dvinal [7]

The three stages that have to do with fluency, progression and automaticity are found in the Number Sense and Operations .

<h3>What is the number sense and operation strand of mathematics?</h3>

This is the part of mathematics that is known to teach the student basic ways to carry out number operations in mathematics. This has to do with representation of numbers as well as solving for the existing relationships in these numbers.

Having a sense of numbers is a very important ability skill that has to be developed early is students to enable them progress in the subject.

If 2L of solution needs to be administered through an IV over 24hours, then how many mililitres of solution needs to be provided

kow [346]

Answer:

83.33 milliliters

Step by step explanation:

2L = 2000 ml Change the liters to milliliters first

2000 ml : 24 hours

x ml : 1 hour

Next you cross multiply : 2000 × 1 hour = 2000 and 24 × x = 24x

Then you divide:

$\frac{24x}{24} : \frac{2000}{24}$

x : 83.3333333...

When this is rounded off it is equal to 83.33

A plane flies 545 kilometers with a bearing of 316° from Naples to Elgin (see figure). The plane then flies 680 kilometers from

anastassius [24]

Answer:

235°

Step-by-step explanation:

Use of low of sines
Consider triangle CEN
Bearing of angle counted from zero to the vector of flight

We have

∠CNE = complementary with 44° ⇒ m∠CNE = 90° - 44° = 46°
NE = b = 545 km
EC = a = 680 km
∠ECN = x

Find the measure of angle x:

sin 46° / a = sin x / b
sin 46° / 680 = sin x / 545
sin x = 545 sin 46 deg / 680
x = arcsin (545 sin 46 deg / 680)
x = 35° (rounded)

Bearing of the flight from Elgin to Canton is:

270° - 35° = 235° as the vector is in the third quadrant
