Answer:

307

Step-by-step explanation:

You get the area from every side like so-

12 * 11= 132

12 * 5= 60

12 * 5=60

5 * 11 = 60

You add them all up to get 307.

I don't know if that's a 5 or a 3 on the side there but I can edit this if it's a different number.

8(1/4x + 12 - 1/2x) = 82

Answers

Answer:

x=7

Step-by-step explanation:

8(1X/4 +12 - 1 x 1/2X)=82

8(X/4 +12-1 x 1/2 x X)=82

8(X/4+ 12 - 1/2x)=82

8 X x/4 + 96+8 X -x/2=82

2x +96 +8 X -x/2=82

2x +96+ 8(-1)/2=82

2x +96 -8x/2 =82

2x+96-4x=82

-2x+96=82

-2x=-14

Step-by-step explanation:

Answer:

x = 6

y = 2

Step-by-step explanation:

From the second equation (x - 3y = 0) we know that x = 3y, now we just substitute 3y instead of "x" in the first equation and get...

x + 2y = 10

3y + 2y = 10

5y = 10

y = 2

Now we can find "x" since we know what "y" is equal to.

x + 2y = 10

x = 10 - 2y

x = 10 - (2)(2)

x = 10 - 4

x = 6

Answers

Answer:

d= 90 degrees

e= 66 degrees

f= 114

Step-by-step explanation:

D is 90 because the measure of the angle on the line is 180 and it shows that the other angle is 90 and 180- 90= 90. E is 66 because opposite angles are congruent. F is 114 because they lie on a straight line which has the measure of 180 and 180- 66= 114

Answer:

d = 90°

e = 66°

f = 114°

Step-by-step explanation:

d = 90°

e = 66°

Reason : Vertically opposite angles

Angles f and 66° are in the linear pair.

f + 66° = 180°

f = ( 180 - 66 )°

f = 114°

What is the area of the shaded sector?

Answers

Answer:900 square units

Step-by-step explanation:

The radius is 90 units. Then the area of the shaded sector will be 900π square units.

What is the area of the sector?

Let r be the radius of the sector and θ be the angle subtended by the sector at the center. Then the area of the sector of the circle will be

A = (θ/360°) πr²

The circumference of circle T is 180π units. Then the radius of the circle is given as,

C = 180π

2πr = 180π

r = 90 units

Then the area of the sector is given as,

A = (40°/360°) π x 90²

A = 900π square units

The area of the shaded sector will be 900π square units.

The answer is 5

Answer:

n = 5 units

Step-by-step explanation:

We can solve this using 2 different equations which lead to the same answer:

Equation #1: Sin(30) = n/10

=>Sin(30) * 10 = n

=> 5 = n

Equation #2: Cos(60) = n/10

=> Cos(60) * 10 = n

=> 5 = n

If a number is a whole number, it is in it's simplest radical form, therefore;    n = 5 units is the correct answer

What are arithmetic operations?

The most fundamental operations in arithmetic are addition, subtraction, multiplication, and division. However, arithmetic also includes more complex operations like manipulating percentages, square roots, exponentiation, logarithmic functions, and even trigonometric functions, which are analogous to logarithms. Other examples of more complex operations include exponentiation. Arithmetic expressions must be evaluated in accordance with the intended order of operations.

Given total amount Renee have = $60

Cost for entry in park = $25

The amount left with Renee = 60 - 25

The amount left with Renee =  $35

now cost for each game is $3

total no. of games can be played in $35 = [tex]\frac{ The amount left with Renee}{ cost for each game}[/tex]

 35/3  = 11.667

Hence we only count integer digits which is 11; so  Renee can play 11 different games.

Investment a starts with $1000 and increases its value by $80 each week. Investment b starts with $2000 and loses $50 of its value each week.After how many weeks will the two investments have the same value?

Answers

Answer:

33.3 weeks

Step-by-step explanation:

Let us represent number of weeks = w

Investment a starts with $1000 and increases its value by $80 each week.

$1000 + $80 × w

1000 + 80w

Investment b starts with $2000 and loses $50 of its value each week.

$2000 - $50 × w

2000 - 50w

After how many weeks will the two investments have the same value?

1000 + 80w = 2000 - 50w

Collect like terms

80w + 50w = 2000 - 1000

130w = 1000

w = 1000/30

w = 33.333333333 weeks

Approximately

After 33. 3 weeks, the Investment will have the same value
