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.

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

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.

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

The point of concurrency of the three median is the centroid of the triangle ABC.

Reasons:

The given parameters are;

The medians of the triangle ABC = Segments BF, CD, and AE

The  length of segment FK = 3.40

Length of segment EK = 1.63

Required:

The sum of the lengths of segment AK and BK

Solution:

The ratios of the lengths of AK to KE = 2:1

Therefore, we have;

[tex]\dfrac{AK}{KE} = \dfrac{2}{1} = \mathbf{\dfrac{AK}{1.63}}[/tex]

1.63 × 2 = 1 × AK

AK = 3.26

Similarly, we have;

[tex]\dfrac{BK}{KF} = \dfrac{2}{1} = \mathbf{\dfrac{BK}{3.40}}[/tex]

3.40 × 2 = BK

6.80 = BK

Which gives;

AK + BK = 3.26 + 6.80 = 10.06

The sum of the lengths of AK and BK = 10.06

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.

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.

Step-by-step explanation:

When you convert, you will receive the same result.

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
