Answer:

The equation of the sunflower's height is h = 18+2.5w

Since the number 18 remains constant regardless of the change in number of weeks, we know that at the start h (w=0) = 18 + 2.5 x 0.

This means that, when Jin planted the sunflower, the sunflower's height was already 18 inches.

For such a reason, we can conclude that the number 18 could represent the sunflower's height at the start (original height).

The mug has a capacity of 2 1/4 cups of water, as per the given conditions.

Given that,
A mug is 1/3 full. The mug contains 3/4 of a cup of water. Find the capacity of the mug.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
As
1 / 3 of mug = 3 / 4 cups
1 of mug = 3/4 / [1/3]
1 of mug = 3×3 / 4
1 of mug = 9 / 4 cups or 2 1 / 4 cups

Thus, the mug has a capacity of 2 1/4 cups of water, as per the given conditions.

Step-by-step explanation:

The equation indicates the line has a positive slope and a y-intercept of 0.  The only graph that corresponds to those conditions is Graph A.

The values of x and y are -49/4 and -15/8 respectively for the given set of equations -2x + 4y = 17 and 3x - 10y = -3.

An equation is a combination of different variables, in which two mathematical expressions are equal to each other.

The given pair of equations,

-2x + 4y = 17      (1)

3x - 10y = -3      (2)

Multiply equation (1) with 3 and equation (2) with 2  

-6x + 12y = 51         (3)

6x - 20y = -6          (4)

Add equation (3) and (4),

- 8y = 15

y = -15/8

Substitute the value of  y in equation (1)

-2x + 4 (-15/8) = 17

-2x - 15/2 = 17

-2x = 49/2

x = - 49/4

The values of x and y for the given equations are -49/4 and -15/8 respectively.

For the given equation the value of x and y will be 15/4 and 17/8 respectively

An equation is a statement that two expressions, which include variables and/or numbers, are equal. In essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.

It is given that, the equations are,

-2x+4y=17 -------(1)

3x-10y= -3

The value of x from equation 1 is,

-2x+4y=17

x=(17-4y)/2 -------(2)

Substitute the value of x in equation 2,

3x-10y=-3

3(17-4y)/2-10y= -3

y=17/8

The value of x is obtained as,

x=15/4

Thus, for the given equation the value of x and y will be 15/4 and 17/8 respectively

The length of the side c is equal to 29.54 approximately to 2 decimal place, using the sine rule.

The sine rule is a relationship between the size of an angle in a triangle and the opposing side.

For the triangle ABC, by sine rule;

a/sinA = b/sinB = c/sinC

We first derive the angle C as follows:

46° + 73° + C = 180° {sum of interior angles of a triangle}

C = 180° - 119

C = 61°

Thus by sine rule;

c/sin61° = 32.3/sin73°

c = (32.3 × sin61°)/sin73° {cross multiplication}

c = 29.5410

Therefore, by proper application of the sine rule we have the length of the side c to be equal 29.54 approximately to 2 decimal place.

Step-by-step explanation:

Answer:

y = -1/3x + 2

Step-by-step explanation:

Slope-intercept form of a linear equation is written as:

y = mx + b, where x and y are coordinates from one of the points on the line, m is the slope, and b is the y-intercept.

1. You'll first want to find the slope, m. Slope can be calculated from two points by using the equation (y1 - y2)/(x1 - x2). If you plug your two points into this equation for x and y (making sure that y1 and x1 are from the same point and y2 and x2 are from the other), you'll get,

(3 - 1)/(-3 - 3) = 2/-6 = -1/3

m = - 1/3

2. You can then plug your slope, m, into the slope-intercept form of the equation. Using one of your points (doesn't matter which, but I'll use (3,1)), you can solve for b, your y-intercept.

1 = -1/3(3) + b

1 = -1 + b

b = 2

3. Plug the variables into the equation.

For your final equation, plug the slope, m, and y-intercept, b, that you just found.

y = -1/3x + 2

Expressions that represent the total cost of the field trip is

0.8{10x + 20y}.

A mathematical expression is made up of numbers, variables, and functions (such as addition, subtraction, multiplication or division etc.)

It is possible to compare expressions and phrases. In English, a phrase by itself could contain an action, but it doesn't constitute a full sentence.

As instances of expressions and how they connect to word phrases, consider the following:

Example: 3 + 7

The phrase "the product of three and seven"

Cost of Ticket for each student cost = $10

Cost of Ticket for each Teacher cost = $20

Let the total students be x

and, total number of teacher will be y

Total cost= 10x + 20y

As museum gives 20 % rebate for promotion

So, now total cost will be {10x + 20y} - 20/100 {10x + 20y}

So the required Expression would be 0.8{10x + 20y}.

The equation which models the distance of the turtle from the pond is q = 26.2 + 3.5p. Option D. is the answer

Given that:

A turtle is 26.2 meters from a pond when it starts crawling toward the pond

The turtle crawls straight toward the pond at a constant rate of 3.5 meters per minute

q represents the turtle's distance, in meters, from the pond and p represents the number of minutes since it started crawling toward the pond

The linear equation is of the form y = mx + c

where m is the rate of change and c is the starting point or y-intercept

m = 3.5 meters per minute, c = 26.2 meters

y = q ( turtle's distance) and x = p (number of minutes)

Thus, the equation models the distance will be:

q = 26.2 + 3.5p

It will take 6 months for Omari to finish paying off the monthly payment for the computer.

What is the monthly payment?

The amount paid each month to repay the loan over the course of the loan is known as the monthly payment. When a loan is taken out, not only the principal, or the original lent amount, but also the interest that accrues, must be repaid.

Given, the total price of the computer = $1,099

down payment = 20% of $1,099 = $219.8

The remaining amount = $1,099 - $219.8 = $879.2

monthly payments for the computer = $144

Then, the total months to pay = 879.2/144 = 6 months

Step-by-step explanation:

120 thousand cars were manufactured in a country in the year 2004-O5. The production of cars increased to 150 thousand in 2005-06. Find the percentage increase in the manufacture of cars.

(150 - 120) / 120 = 0.25

0.25 = 25% increase

The output values from the rule are -12, 2, 0, -6 and -10

From the question, we have the following parameters that can be used in our computation:

Rule = add -6

This means that

Output = Input - 6

Using the values in the question, we have

Output = -6 - 6 = -12

Output = 8 - 6 = 2

Output = 6 - 6 = 0

Output = 0 - 6 = -6

Output = -4 - 6 = -10

Answer:

[tex]\huge{\boxed{\text{The height of the triangle is 6cm.}}}[/tex]

Step-by-step explanation:

This question requires us to use a system of equations.

The area of a triangle is (1/2) * (base) * (height).

Thus, if b = base, and h = height

[tex]\frac{1}{2} bh=36[/tex]

Additionally, from the problem, we know:

[tex]b=h+6[/tex]

Then, via substitution, we can get

[tex]\frac{1}{2} *(h+6)*h=36[/tex]

Then, simplify:

[tex]\frac{1}{2} h^2+3h=36[/tex]

[tex]\frac{1}{2} h^2+3h-36=0[/tex]

[tex](\frac{1}{2} h-3)(h+12)=0[/tex]

Thus, the height must equal either 6 or -12, and because height cannot intrinsically be negative, the height must be 6.
