A linear equation is an equation in which the highest power of the variable is always 1. The standard form of a linear equation in one variable is of the form Ax + B = 0. where, x is a variable, A is a coefficient and B is constant. The standard form of a linear equation in two variables is of the form Ax + By = C. where, x and y are variables, A and B are coefficients and C is a constant.

represent the number on the board by x, the result of the second student by y , therefore the result of the first student is 2y

solving for the first student, 12+x= 2y

for the second student , 3x= y

substituting 3x for y in first equation

12+ x= 2(3x)

12+x= 6x

collecting like terms

5x= 12

divide both side by5

x= 12/5= 2 2/5.

The winner received 53 of the 75 votes in the student gov. election according to provided ratio.

What is ratio?

In arithmetic, a magnitude relation shows range times one number contains another.

Main body:

Because the ratio of students who voted for the winner compared to all students who voted is 0.70

we can rewrite this as:

0.70 = 70/100

And, because we know the total number of students who voted is 75 and if we call the number of students who voted for the winner s , we can then write this relationship and solve for s :

[tex]\frac{70}{100} = \frac{s}{75}[/tex]

Multiplying both sides by 75.

75*[tex]\frac{70}{100} = \frac{s}{75}[/tex]*75

s= 75*70/100

s = 5250/100

s = 52.5

s ≈ 53.

1. The length of RS is 5.

2. The length of JK is 6.

3. The length of RT is 4.

4. The perimeter of triangle JKL is 24.

What do you mean by right angle triangle?

A right triangle, also known as a right-angled triangle, right-perpendicular triangle, orthogonal triangle, or formerly rectangled triangle, is a triangle with one right angle, or two perpendicular sides. The foundation of trigonometry is the relationship between the sides and various angles of the right triangle.

According to data in the diagram of the given question:

We have :

The ΔJKL, ΔRKS and ΔRTS are right-angle triangle.

The length of RK=3 and KS=4

We are using pythagoras theorem for determine the length of RS,

(RK)²+(KS)²=(RS)²

(3)²+(4)²=(RS)²

9+16=(RS)²

25=(RS)²

(5)²=(RS)²

RS=5

∴ The the length of RS is 5.

Now, we need to find the length of JK,

JK=2(RK)=2(3)=6

JK=6       [Because RK is midpoint of the side JK]

We have given value of KS=4 and the side KS is the opposite side of RT,

So, that's why the value of RT=4.

Now, we will find the perimeter of ΔJKL,

JK=6, KL=8 and we need to find the side JL,

(JK)²+(RL)²=(JL)²

(6)²+(8)²= (JL)²

36+64=(JL)²

100=(JL)²

(10)²=(JL)²

JL=10

The perimeter of the triangle ΔJKL,

Perimeter=6+8+10=24

Therefore, the perimeter of the triangle is 24.

The exponential equation represents an exponential growth because the rate of decay is 1.02 which is greater than 1.

y = 90(1.02)^x

The general form equation is:

y(x)= a(1+r)^x such that r is the decay percent.

on comparing,

1 + r = 1.02

r = 1.02 - 1

r = 0.02

converting into percent

r = 0.02 * 100

r = 2%.

Answer:

c

Step-by-step explanation:

To find a perpendicular line, you must compare the slopes. With the equation y=2x-5, we're looking for the inverse/opposite slope of -1/2.

Option A still has a slope of 2. Option B, when everything is in the format of mx+b = y format is -x-4=-2y. which gives us 1/2 but not -1/2. C when everything is on the right side gives us -2y=x-6. Divide both sides by -2 to get the y by itself and you're left with y = -1/2x+3. Now we found the equation that gives us the -1/2 slope we were looking for.

The value of 9 pounds of blueberries is $24.75.

The value of 5 pounds of blueberries is $13.75.

The fact that the Blueberry Farm sells 6 pounds of blueberries for $16.50 implies that the cost per pound will be:

= $16.50 / 6

= $2.75

Therefore, 9 pounds of blueberries cost:

= Cost per pound × 9

= $2.75 × 9

= $24.75

5 pounds of blueberries will cost:

Answer:

its A.

Step-by-step explanation:

For the given geometric mean of a required number and nine times the required number is 30 then the required number is equal to 10.

As given in the question,

Geometric mean GM = 30

Let us assume the first number is x

and second number i.e. 9 times of the first number is 9x

By the formula GM = [tex]\sqrt{x.y}[/tex]

Now putting the value

30 = [tex]\sqrt{x.9x}[/tex]

30 = [tex]\sqrt{9x^{2} }[/tex]

30 = 3x (∴ square root of 9 is 3 and sq root of x² is x)

10 = x  (by dividing both the side by 3)

Therefore, for the given geometric mean of a required number and nine times the required number is 30 then the required number is equal to 10.

The asked percentages are given as

1. 90 is 100% of 90.

2. 9 is 10% of 90.

3. 27 is 30% of 90.

A percentage is a particular number or fraction in every hundred. The denominator of the fraction is 100, and it is represented by the symbol "%."

The purpose of percentage calculations is to determine the percentage of a whole in terms of 100. A percentage can be determined using one of two methods:

It should be noted that when the denominator is not a power of 100, the second technique of percentage computation is not used.

Given, a comb has 90 teeth.

1. Find out what percentage of 90 is 90 now.

Let the percentage be x,

(x/100) × 90 = 90

x = (90 × 100)/90

x = 100 %

2. Now, find what percent of 90 is 9.

Let the percentage be x,

(x/100) × 90 = 9

x= (9 × 100)/ 90

x = 10%

3. Now, find what percent of 90 is 27.

Let the percentage be x,

(x/100) × 90 = 27

x= (27 × 100)/ 90

x = 30%

The rate at which the height of the water changes when the water is 1m deep is; dh/dt = 1.5m/min

We are given;

width; w = 3m

Height; h = 4m

Length of trough; L = 10m

According to similar triangle property; w =3/4h

volume of water; V = 1/2×w×h×L = 1/2 × 3/4h × h × 10 = 15/4 h²

Differentiate using chain rule for both sides with respect to t gives;

dV/dt = (1/2)(15/2)h(dh/dt).

Now, we are given dV/dt = 5m³/min and we want to find the rate at which the height of water changes when the water is 1 m deep.

Thus;

5 = ×dh/dt

At h = 1m; 5 = 15(1)/2 × dh/dt

⇒ dh/dt = 2/3

dh/dt = 1.5 m / min

A) 1,100 hours is equal to approximately 104days in Saturn.

B) You need to know how hours make 1day in Saturn. i.e 10 hours 34minutes or 10.567hours.

From the question note that the number of hours in one day is different for each planet.

Hence for Saturn;

1 day =  10hours.34minutes

X day   =1,100 hours

Note; 34 minutes in hours will be:

60 minutes  =1hour

34/60      =0.567hour

Thus;

10hours.34minutes   =   10hours +0.567hour

                                   =10.567hours

To find the number of days in 1,100 hours, we cross multiply;

X day  * 10.567hours =1,100 hours * 1 day

       X day  =     1,100 hours * 1 day

                               10.567hours

       X day    =104.1  ≈ 104 days

Therefore, you need to know the number of hours that makes a day in Saturn.i.e 10 hours 34minutes or 10.567hours.

Answer:

The slope of y = 5x - 4 is 5.

Notice that the equation, y = 5x - 4, of the line is written in the form y = mx + b. Thus, it is in slope-intercept form. When the equation of a line is in slope-intercept form, we know that the slope of the line is equal to m, the coefficient of x.

In y = 5x - 4, the coefficient of x is 5. Thus, the slope of the line, y = 5x - 4, is 5.
