Linnea's company's revenue in 2017 is 36/25 of its revenue in 2016. What is Linnea's company's revenue in 2017 as a percent of its revenue in 2016?

Solution

Let

36x= Linnea's company revenue in 2017

25x=Linnea's company revenue in 2016

Percent of Linnea's company's revenue in 2017 as a percent of its revenue in 2016= 36x / 25x × 100

36x / 25x * 100

=1.44 × 100

The batches of brownies can Luisa make is 4 batches.

It is required to find the the batches of brownies can Luisa make.

Arithmetic is the branch of mathematics that deals with the study of numbers using various operations on them. Basic operations of math are addition, subtraction, multiplication and division. These operations are denoted by the given symbols.

Given:

3 batches of brownies from 3/2 cups of chocolate left.

Step-by-step explanation:

From the question, we know that:

1/2 cups of chocolate = 1 batch of brownies

3/2 cups of chocolate = x

Cross Multiply

1/2 × x = 3/2

x = 3/2/1/2

x = 3/2 × 2/1

x = 3 batches.

That means she can make 3 more

3+1=4

Therefore, the batches of brownies can Luisa make is 4 batches.

Answer:

16.12 units

Step-by-step explanation:

distance formula: d = √[(x₂ - x₁)² + (y₂ - y₁)²]

d = √[(8 - 10)² + (7 + 9)²]

d = √[(-2)² + (16)²]

d = √[4 + 256]

Greetings from Brasil...

See the attached chart. The midpoint, M, has 8 units down on the Y axis. So the other half will also have 8 units after that point M. This is also true for the X axis.

Just make the difference between points T and M. For M and S they are the same quantities.

(0; 3) and (1; -5)

X: 1 - 0 = 1   (one unit until mid point)

Y: - 5 - 3 = - 8  (8 units until mid point)

To S:

S(W; Z)       M = center point coordinate value

W = M +  1 ⇒ W = 1 + 1 = 2

Z = M - 8 ⇒ Z = - 5 - 8 = - 13

Answer:

√29 units

Step-by-step explanation:

Find the distance between (-1,4) and (1,-1).

We'll use the Pythagorean Theorem:

The horizontal distance between the two points is 1 - (-1), or 2, and the vertical distance is 4 - (-1), or 5.

Thus, the distance squared is 2^2 + 5^2, or 29, and the distance between the two points is therefore

d = √29 units

Answer:

What is the change in y-values from

Point A to Point B?

50

What is the change in x-values from

Point A to Point B?

1

What is the rate of change of the linear function?

50

feet per second

Step-by-step explanation:

The change in y-values from Point A to Point B is from 0 to 50feet.  What is the change in x-values from Point A to Point B is 0 to 1 second. Rate of change of the linear function is given by y = 50x (feet per second).

" Linear function is defined as the algebraic expression which represents the relation between the variables with highest exponent equals to 1."

Formula used

[tex]\frac{y-y_{1} }{x-x_{1} } =\frac{y_{2} -y_{1}}{x_{2} -x_{1}}[/tex]

According to the question,

Given,

Speed of Red kangaroos can reach = 50 feet per second

Number of feet represent by y - axis

Time represent by x-axis

When

[tex]x_{1} = 0 seconds \\\\y_{1} = 0 feet[/tex]

When

[tex]x_{2} = 1 seconds \\\\y_{2} = 50 feet[/tex]

Change in y-values from point A to B  is given by [tex](y_{1}, y_{2} ) = (0,50)[/tex]

Change in x-values from point A to B  is given by [tex](x_{1}, x_{2} ) = (0,1)[/tex]

Rate of change of the linear function

[tex]\frac{y-0 }{x-0 } =\frac{50-0}{1-0}[/tex]

⇒[tex]y= 50x[/tex]

Hence, the change in y-values from Point A to Point B is from 0 to 50feet.  What is the change in x-values from Point A to Point B is 0 to 1 second. Rate of change of the linear function is given by y = 50x (feet per second).

Step-by-step explanation:

Nadia is carrying out mountain climbing.

She started climbing the mountain at an altitude of 19.26 feet below the sea level.

Nadia changed her altitude by climbing a total of 5,437.8 feet from her starting position.

Therefore, Nadia's altitude at the end of her climb can be calculated as follows

= 5,437.8-19.6

= 5,418.2

Hence Maria's altitude at the end of her climb is 5,418.2 feet

Answer:

30,370 feet

Step-by-step explanation:

The difference in elevations between two points will be 30370 feet.

It is given that Mt. Everest is 29000 feet above sea level and the shore of dead sea is 1370 feet below the sea level.

We have to find out the difference in elevation between the two points.

What is algebra ?

Algebra is the branch that deals with various symbols and the arithmetic operations such as addition , subtraction , etc.

As per the question ;

Height of Mt. Everest from sea level = 29000 ft. above

Height of shore of dead sea from sea level = 1370 feet below

As these both are in opposite directions , i.e., one above sea level and other below sea level , we should add both of these to find the difference in elevations between these two points.

i.e.,

The difference in elevations between two points will be ;

= 29000 + 1370

= 30370 feet

Thus , the difference in elevations between two points will be 30370 feet.

Answer:

The table represents a proportional relationship

Step-by-step explanation:

Given

x ------ y

1 ------- 15

2 --------30

4 ---------60

5 -------- 75

Required

Determine if the table shows a proportional relationship

To check this, we make use of the following formula;

[tex]k = \frac{y}{x}[/tex]

Where k is the proportionality constant

When x = 1, y = 15

[tex]k = \frac{15}{1} = 15[/tex]

When x = 2, y = 30

[tex]k = \frac{30}{2} = 15[/tex]

When x = 4, y = 60

[tex]k = \frac{60}{4} = 15[/tex]

When x = 5, y = 75

[tex]k = \frac{75}{5} = 15[/tex]

Since the value of k for all values of x and y is the same; i.e. 15

Then, the table represents a proportional relationship

smith will run out by week 2

Answer:

After 17 weeks

Step-by-step explanation:

We can create a system of equations for this problem, where y is the total amount of money in their banks and x is the amount of weeks passed.

Mr. Smith's equation will be [tex]y = 12x+21[/tex].

Mr. Brown's equation will be [tex]y = 10x+55[/tex].

We can now solve for x by using substitution.

Let's substitute Mr. Brown's equation into Mr. Smith's equation.

This get us [tex]10x + 55 = 12x + 21[/tex].

We can now solve for x.

Let's subtract 12x from both sides:

[tex]-2x + 55 = 21[/tex]

And now let's subtract 21 from both sides:

[tex]-2x+34=0[/tex]

Now we subtract 34 from both sides:

[tex]-2x=-34[/tex]

And divide both sides by -2.

[tex]x=17[/tex]
