Total amount raised for the cookies is $75, Option C is correct.

Two or more expressions with an Equal sign is called as Equation.

Given that Cupcakes were sold for two dollars each.

Cookies were sold for $0.50 each.

The members sold a total of 450 items.

Let x be the number of cupcakes and y be number of cookies

x+y=450

Of the items sold 2/3 were cupcakes and the remaining items were cookies.

x = 2/3×450 = 300

Y= 450 - 300 = 150

The total amount raised from the cupcakes is $2× 300 = $600.

The total amount raised from the cookies is $0.50 × 150 = $75.

Hence, total amount raised for the cookies is $75, Option C is correct.

A water sprinkler has a rotational motion in order to reach a broad area

from its stationary location.

The time it takes the sprinkler to reach the far right position is 36 seconds.

Reasons:

The given parameter are;

The angular speed of the water sprinkler, ω = 5° per second

Location where the sprinkler starts = The far left position

Required:

The time it takes the sprinkler to reach the far right position.

Solution;

The angle covered by moving from the far left to the far right, θ = 180°

Time required is given as follows;

[tex]\omega = \mathbf{\dfrac{\theta}{t}}[/tex]

Therefore;

[tex]t = \dfrac{\theta}{\omega}[/tex]

Which gives;

[tex]t = \dfrac{180 ^{\circ}}{5^{\circ}/s} = 36 \, s[/tex]

The time it takes the sprinkler to reach the far right position, t = 36 seconds.

Answer:

0.07

Step-by-step explanation:

I'm sorry if its wrong

The probability that the hens lay a total of two eggs is 0.07. Therefore, the option B is the correct answer.

Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.

We know that, probability of an event = Number of favourable outcomes/Total number of outcomes.

Given that, Hannah has a chicken coop with six hens.

Let X represent the total number of eggs the hens lay on a random day.

Let the probability that the hens lay a total of two eggs be y

From the table,

X=0.02+0.03+y+0.12+0.30+0.28+0.18

We know that, the total of probability should be 1.

Now, 1=0.02+0.03+y+0.12+0.30+0.28+0.18

1=0.93+y

y=1-0.93

y=0.07

Therefore, the option B is the correct answer.

Answer:

The length = 35 ; The width = 12

Step-by-step explanation:

Perimeter = 2L + 2W

Length = x

Width =  x - 23

94 = 2(x)  + 2(x - 23)

94 = 2x + 2x - 46

94 = 4x - 46

94 + 46 = 4x

140 = 4x

140/4 = x

35 = x           The length = 35; The width = (35 - 23) =  12

Answer:

Step-by-step explanation:

Width

1/2 cm = 5 feet

2cm = x                    Cross Multiply

1/2 x = 2 * 5              Combine

1/2 x = 10                  Multiply both sides by 2

x = 20

Length

1/2 cm = 5 feet

4 1/4 cm = x              Cross Multiply

1/2 x = 4 1/4 * 5         Combine the right

1/2 x = 21.25              Multiply both sides by 2

x = 42.5                    

Room Area

Area = 20 * 42.5

Area = 850 square feet

Cost

1 square foot costs 8.5 dollars.

850 square feet costs 8.5 * 850

850 square feet costs 7225  dollars.

What is x in x^2-x-6=0 pls

x^2 - x - 6 = 0

x + 2 * x - 3 = 0

x + 2 = 0

x - 3 = 0

x = 2 or -3

Answer:

x= -2 or x= 3

Explanation:

the factors of -6 which sum to -1 are -3 and + 2

(x - 3) (x + 2) = 0

equate each factor to zero and solve for x

x + 2 = 0 ⇒ x = −2

x − 3 = 0 ⇒ x = 3

Answer:

The answer (using BEDMAS) is 27

Step-by-step explanation:

The equation 9 x [(18+2) ÷ 5 - 1] is solved using BEDMAS or PEDMAS

First solve the smaller bracket

18 + 2 = 20

So then it becomes 9 x [20 ÷ 5 - 1]

Do the division inside the bracket next

20 ÷ 5 = 4

Then it becomes 9 x [4 - 1]

Do then subtraction within the bracket

4 - 1 = 3

Then it becomes 9 x 3

Finally solve 9 x 3 which equals 27

Answer:

  a) k = 2/5

  b) y = 2/5x

  c) y = 2 3/5

Step-by-step explanation:

The proportional relation is described by the equation ...

  y = kx . . . . . . k is the constant of proportionality

The value of k can be found by dividing the equation by x:

  y/x = k = (2 1/4)/(5 5/8) = (9/4)/(45/8) = 18/45

  k = 2/5

__

As above, the equation is ...

  y = kx

  y = 2/5x

__

Using 6.5 for x, we have ...

  y = (2/5)(6.5) = 2.6 = 2 3/5

m ∠APQ = m ∠RQP = 62°       If parallel lines, then alternate interior angle =

  m ∠DRP + m ∠PRQ = 180°   These angles form a linear pair which = 180°

         115° + m ∠PRQ = 180°      Substitution

  m ∠PRQ = 65°                  Subtraction  

m Δ QPR = 180°                       Definition of triangle

m Δ QPR = m ∠PQR + m ∠QPR + m ∠PRQ    the sum of the angles of triangle

    180° =  62° +  x  + 65°

    180 =  127 +  x

    53 = x

bearing in mind that a cube has all equal sides, Check the picture below.

ok done. Thank to me :>

Answer:

Step-by-step explanation:

Let x be the portion of 60%

180 - x is the portion of 40%

0.60x + 0.40(180 - x) = 0.55(180)

0.60x + 72 - 0.40x = 99

0.20x = 27

x = 135

180 - 135 = 45

First brand = 45 gallons of 40%

Second Brand = 135 gallons of 60%
