Answer 1

Answer:

1.363

Step-by-step explanation:

Area of the sector is x/360 * pi * r^2

A = 40/360 * pi * 7*7

= 1/9 * 22/7 * 49

= 1/9 * 22 * 7

= 17.111111

Area of the triangle OMN = 1/2 ab sin C

so here A = 1/2 * 7 * 7 * sin 40

= 49/2 * sin 40

= 15.748296437320213494904763542728

so, Area of shaded segment is

= Area of sector - area of triangle

= 17.1111111 - 15.748296437320213494904763542728

= 1.363

she would save on one visit

12/2 = $6 plus the $10 for snacks = $16

so, she would save in one year

52×16 = $832

Answers

Answer:

See answer below.

Step-by-step explanation:

1. Start at point (0,0), This point is where the x-y-axis meet. Do not put a dot

there because this is your starting point.

2. Move to the left over to point -1 3/4 . This place is between -1 and -2, and

closer to -2 because the point is -1 .75. Remember this point is not on the

graph.

3. Now move up from that point to 4.5 and put a dot at that place. The point is in the Q II , to the left top.

five more than one-third of a number is -2. Find the number

Answers

Answer:

x = -21

Step-by-step explanation:

Words To Algebra:

Words : Five more than one-third of a number = -2

Algebraic Equation: 5 + (1/3)x = -2

Isolate x:

5 + (1/3)x = -2 [tex]\longmapsto\\[/tex] Subtract 5 from both sides

5 + (1/3)x - 5 = -2 - 5

(1/3)x = -7 [tex]\longmapsto\\[/tex] Multiply All sides by 3

(1/3)x * 3 = -7 * 3

x = -21

Check:

5 + (1/3)-21 = -2

5 + -7 = -2

-2 = -2

The length of a rectangle is 4 units more than triple its width. If the perimeter is 64,
what is the length of the rectangle?

Answers

Answer: Length = 25, width = 7

Step-by-step explanation:

Let width be w, and length be 3w + 4.

Perimeter of a rectangle = 2l + 2w

64 = 2(3w + 4) + 2w

64 = 6w + 8 + 2w

64 = 8w + 8 [subtract 8 from both side]

56 = 8w [Divide 8 from both side]

w = 7

Plug w in l, where l = 3w + 4 = 21 + 4 = 25

How many gallons of a 50% antifreeze solution must be mixed with 90 gallons of 25% antifreeze to get a mixture that is 40% antifreeze? Use the six-step method.

Answers

Let x be the needed volume of 50% antifreeze solution. x gallons of this solution contains 0.50x gal of antifreeze.

Mixing this amount with 90 gal of 25% solution makes a total volume of (x + 90) gal of solution.

90 gal of 25% solution contains 0.25 (90 gal) = 22.5 gal of antifreeze.

The new mixture would then consist of (0.50x + 22.5) gal.

If its concentration of antifreeze is supposed to be 40%, then

(0.50x + 22.5)/(x + 90) = 0.40

Solve for x :

0.50x + 22.5 = 0.49 (x + 90)

0.50x + 22.5 = 0.49x + 44.1

0.01x = 21.6

x = 2160

Answer:

x = 12.633, -0.633

Step-by-step explanation:

x^2 -12x + 36 = 44

the underlined part is (x - 6) ^2

(x - 6)^2 = 44

(x - 6) = ± [tex]\sqrt{44}[/tex] (both positive and negative)

(x - 6 ) = + 6.6332495807108

x = 12.6332495807108 = 12.633

(x - 6 ) = - 6.6332495807108

x = - 6.6332495807108 + 6

During World War II, the American military found that all its secret codes were being quickly deciphered by talented Japanese code breakers. The Navajo language provided a unique solution. Navajo was incredibly difficult to learn: complex, unwritten, and full of unusual and difficult sounds. So the military hired Navajo "Code Talkers" to send top-secret messages. The Navajo "code" was not only secure, it was fast. With traditional codes, it could take hours to code and decode a message, but Navajo soldiers could translate messages in just a few minutes. The Navajo code was never cracked. For many decades, the U.S. government kept the program a secret.
