The ratio of girls to boys in the class is 3:7.

To calculate the ratio of girls to boys in the class, we need to determine the number of girls in the class.

Given that there are 50 students in total and 35 of them are boys, we can find the number of girls by subtracting the number of boys from the total number of students:

Number of girls = Total number of students - Number of boys

Number of girls = 50 - 35

Number of girls = 15

Now that we know there are 15 girls in the class and 35 boys, we can calculate the ratio of girls to boys.

Ratio of girls to boys = Number of girls / Number of boys

Ratio of girls to boys = 15 / 35

To simplify the ratio, we can divide both the numerator and denominator by their greatest common divisor, which in this case is 5:

Ratio of girls to boys = (15 ÷ 5) / (35 ÷ 5)

Ratio of girls to boys = 3 / 7

This means that for every 3 girls, there are 7 boys in the class. The ratio provides a relative comparison of the number of girls to the number of boys, helping to understand the gender distribution within the class.

The calculation of property tax is typically based on the assessed value of the property and the tax rate set by the local government. The assessed value is determined by a government-appointed assessor who evaluates the value of the property based on factors such as its location, size, age, and condition. The tax rate is then applied to the assessed value to determine the amount of tax owed by the property owner.

Answer:

80 distributions of the three scholarship are possible.

Step-by-step explanation:

Given that 4 freshman, 5 sophomore, and 4 juniors have been nominated to receive a scholarship of $ 500, $ 250, and $ 100, to determine how many distributions of the three scholarship are possible if one scholarship is to be awarded to someone from each class you must perform the following calculation:

4 x 5 x 4 = X

20 x 4 = X

80 = X

Therefore, 80 distributions of the three scholarship are possible.

well, in 2007 it was 12000, so initially that's what it was, and in 2019 it went to 23000, so that's 12 years later, and in 2040, that'll be 33 years later.

The value of x is 24 and different angles of hexagon will be -

A = 160

B = 142

C = 120

D = 156

E = 31

F = 111

An angle is a geometric shape that is defined as the amount of rotation that occurs between two straight lines or planes. Angles are measured in degrees, with 360° representing a full circle.

We need to apply the inverse tangent function to determine the angle at which the sun strikes the flagpole. We are aware that the triangle's adjacent side is 42 feet long and its opposite side is 25 feet tall (the height of the flagpole) (the length of the shadow).

Given the figure is hexagon,

the sum of angles of a hexagon is 720,

Upon adding the given angles,

mA = (7x-8)°

mB (4x+46)°

mC = (5x)

mD = (6x+12)°

mE = (x+7)°

mF = (5x-9)°

⇒ 7x - 8 + 4x + 46 + 5x + 6x + 12 + x + 7 + 5x - 9 = 720

⇒ 28x + 48 = 720

⇒ 28x = 672

⇒ x = 24

Therefore, the angles will be -

A = 160

B = 142

C = 120

D = 156

E = 31

F = 111

According to the statement, the Ship must move at an average pace of 150 meters per hour.

The variable under examination is lessened when the gradient is "downhill" (negative). When used as a gauge of how well things are doing, "downhill" denotes a downward trend. Yet, if this indicates trouble or some other unpleasant quality, the situation is improving.

The chess player Carissa walks very, very slowly. She actually moves at speeds of 100 meters per hr upward, 150 meters per hr on flat terrain, and 200 meters every hour on downhill terrain.

Here,

Carissa traverses Boston on foot from a coffeehouse to a boba store before returning over the same path.

Total distance walked = 2 [200 + 100 + 150] = 900 meter

Total time = 2 [1 + 1 + 1] = 6 hour

Average speed is calculated as distance divided by time (900 / 6 = 150 m/s),

As a result, the needed Carissa average speed is 150 meters per hr.

Answer:

  x + y = 2

Step-by-step explanation:

You want to solve an equation in x and y that is the sum of two square roots equal to a different sum of two square roots.

This necessarily gets messy. You must square the equation, rearrange it to isolate the radicals, and repeat that process two more times. A number of terms cancel, so the result is a 4th degree equation in x and y that can be factored to the square of the product of two linear trinomials.

Here goes:

  \(2x^2 +x +y +9 +2\sqrt{(5 + x + x^2 - y)(4 + x^2 + 2 y)}\\\\=2 x^2 +3x + 3 y+5 + 2\sqrt{(3 + 2 x + x^2)(2 + x + x^2 + 3 y)}\qquad\text{square both sides}\\\\\\x+y-2=\sqrt{(5 + x + x^2 - y)(4 + x^2 + 2 y)}-\sqrt{(3 + 2 x + x^2)(2 + x + x^2 + 3 y)}\\\text{ separate radicals from non-radical terms}\\\\\)

Repeating the process of squaring both sides and separating the radical terms, we get ...

  \(22 + 15 x + 15 x^2 + 4 x^3 + 2 x^4 + 19 y + 6 x y + 4 x^2 y - 3 y^2\\\\=2\sqrt{(3 + 2 x + x^2)(5 + x + x^2 - y)(4 + x^2 + 2 y)(2 + x + x^2 + 3 y)}\)

Ater one final squaring of both sides, we get an 8th-degree equation that can be factored with some difficulty to ...

  \((2 + x - x^2 - 7 y + 2 x y + 3 y^2)^2 = 0\\\\(x -3y +1)^2(x+y-2)^2=0\)

Solutions to this are values of x and y that make the factors zero. The second factor is zero when ...

  (x +y -2) = 0   ⇒   x +y = 2 . . . . . . . . the value the problem is looking for

The first factor is zero when ...

  x -3y +1 = 0   ⇒   x = 3y -1

Using this expression to substitute for x in the original radical equation, we get ...

  \(2\sqrt{5 - 4 y + 9 y^2}=2\sqrt{2 + 9 y^2}\\\\-4y+3=0\qquad\text{divide by 2, square, subtract $2+9y^2$}\\\\y=\dfrac{3}{4}\\\\x=3\cdot\dfrac{3}{4}-1=\dfrac{5}{4}\\\\x+y=\dfrac{5}{4}+\dfrac{3}{4}=2\)

The solution to this equation is x +y = 2.

Additional comment

As we did with x=3y-1, we can substitute x=2-y into the original radical equation. Doing so gives a tautology, good for all values of x and y.

Answer:

Width = 3.773 inches

Length = 79.227 inches-

Step-by-step explanation:

g = 7(3w)             Eq. 1

166 = 2(g+w)       Eq. 2

g = length

w = width

From Eq, 1:

g = 21w              Eq. 3

Replacing Eq. 3 in Eq. 2

166 = 2(21w + w)

166 = 2(22w)

166 = 44w

166/44 = w

w = 3.773

From Eq. 3

g = 21(3.773)

g = 79.227

Check:

From Eq. 2:

166 = 2(79.227 + 3.773) = 2 * 83

THE ANSWER IS IN THE PHOTO

To combine two fractions into one fraction if they are being added / subtracted from each other, make it so they share the same denominator.  To do this, one way is to make \(\frac{1}{3}\) have denominator \(3t\), so multiply the top and bottom of the fraction by \(t\):

\(\frac{t+2}{3t} - \frac{t}{3t}\)

and now you can just subtract the numerator.

\(= \frac{t+2 - t}{3t} = \frac{2}{3t}\)

Answer:

37

Step-by-step explanation:

This may look like a complicated problem but it's some simple analyzing of the problem to get the job done:

"The sum" tells that we are going to be adding together the next two phrases separated by "and"s.

That is "8 times a number 4"  and  "5"

Therefore, we need to add 2 groups:

(8*4) + (5)

Now, we simply use PEMDAS (or GEMDAS) to solve the expression:

(8*4) + (5)

= (32) + (5)

= 32 + 5

= 37
