determine the arc of length AB. Give your answer in TWO DECIMAL PLACES.

Answer:

8π/5

Step-by-step explanation:

Length of an arc, L

L = θ / 360° * (2πr)

r = Radius = 4 ; θ = 72

Hence,

L = 72/360 * (2π4)

L = 1/5 * 8π

L = 8π/5

Answer:

8.4%

Step-by-step explanation:

let x = interest rate

55,000(1 + x)^16 = 200,000

divide both sides by 55,000

(1 + x)^16 = 3.636

find the invese of 16

1 + x = 1.084

x = 0.084

x = 8.4

Answer:

7m

Step-by-step explanation:

18/6 = 3

24/8 = 3

21/x = 3

21/3 = 7

x = 7

Answer:

x = 3.6

Step-by-step explanation:

Since ABCD ~ EFGH, therefore:

AB/EF = AD/EH

AB = 3

EF = 2

AD = x

EH = 2.4

Plug in the values into the equation:

3/2 = x/2.4

Cross multiply

3*2.4 = 2x

7.2 = 2x

Divide both sides by 2

7.2/2 = x

3.6 = x

x = 3.6

Answer:

Commutative property of multiplication

Step-by-step explanation:

Properties of Multiplication:

Commutative:

Multiplying two or more factors in a different order.

ex: 2 x 4 x 5 = 2 x 5 x 4

Associative:

Multiplying factors in parenthesis with different grouping. usually to make the problem simpler.

ex: (13 x 4) x 25 = 13 x (4 x 25)

Distributive:

Distributing a multiplicand to factors in parenthesis.

ex: 2(4 - 1) = 2(4) - 2(1)

ex: 2(8+7) = 2(8) + 2(7)

Answer:

x = 30, y = 15

Step-by-step explanation:

x = 2*15 = 30

(Central angle is twice the inscribed angle standing on the same arc.)

Similarly,

y = 15

(Base angles of isosceles triangle are equal)

Given:

The table of point scored in 5 games.

After game 6, the mean number of points scored per game is 9.

To find:

The points scored by Maya in game 6.

Solution:

Let x be the points scored by Maya in game 6. Then sum of scores in all 6 games is:

[tex]Sum=8+12+10+6+14+x[/tex]

[tex]Sum=50+x[/tex]

We know that, the formula for mean is:

[tex]\text{Mean}=\dfrac{\text{Sum of all observations}}{\text{Total number of observations}}[/tex]

So, the mean number of points scored per game is:

[tex]\text{Mean}=\dfrac{50+x}{6}[/tex]

It is given that the mean number of points scored per game is 9.

[tex]\dfrac{50+x}{6}=9[/tex]

[tex]50+x=9\times 6[/tex]

[tex]x=54-50[/tex]

[tex]x=4[/tex]

Therefore, the correct option is A.

Step-by-step explanation:

Answer:

P'(C) = 0.98

Step-by-step explanation:

Given that,

P(C) = 0.02 (The probability of getting C)

We need to find the complement of P(C) i.e. P'(C).

We know that,

P(C)+P'(C)=1

P'(C) = 1-P(C)

= 1-0.02

= 0.98

So, the complement of P(C) is equal to 0.98.

C = StartFraction pi times 4 over 2 EndFraction.

Answer: No.

Step-by-step explanation:

The reason why it is not enough is that 0.45 kilograms is 450 grams, and when you divided 450 by 9, you get 50, which is 10 less than 60. Therefore, 1 bottle of spice is not enough for 9 weeks.

Answer:

No

Step-by-step explanation:

Half of a kilogram or 0.5 is 500 grams.

The total grams for nine weeks (60 x 9) is 540

Since Martha bought a 0.45 kilogram bottle, which is less than a half, she doesn't have enough of the spice.

Martha would need a 0.54 kilogram bottle to have the right amount.

Answer:

58.1

Step-by-step explanation:

Answer:

72 in²

Step-by-step explanation:

We obtain the value of EC:

From Pythagoras :

EC = √CD² - DE²

EC = √10² - 6²

EC = √100 - 36

EC = √64

EC = 8

To obtain AE:

AE = √AB² - BE²

AE = √(√52)² - 6²

AE = √52 - 36

AE = √16

AE = 4

Hence, we can obtain the areas of each triangle :

△ABE = △ADE

△BCE = △CDE

AREA OF △ABE = 1/2 * base * height

= 1/2 * 4 * 6 = 12 in²

AREA OF △BCE = 1/2 * base * height

= 1/2 * 6 * 8 = 24 in²

HENCE, total area of fabric :

(2 * 12) + (2 * 24)

24 in² + 48 in²

= 72 in²
