1. Divide the amount of ounces needed for one pitcher of lemonade by the amount of ounces she has to get 16 pitchers of lemonade.

Answer: 33 in.

Step-by-step explanation: If the triangles are similar, you have to compare the same sides and find the scale. If you rotate the image, you see the 6 is the same side as the 18. A scale of 18:3 is the same as 3:1. Using this, you can see the missing side and 11 are the same, so you multiply the 11 by 3 to gett 33 as the length, and in. as your label.

Exponential Model

Some phenomena can be modeled as an exponential function of the form:

Where Po is the initial value, r is the rate of change, and t is the time.

If the value of P decreases in time (decaying function), then r is negative. If the value of P increases in time (growth), then r is positive.

We know an investment of Po=$4500 has been losing value (decay) at a rate of r = -2.5% = -0.025 each year.

The value of the investment when t = 5 years is:

Calculating:

The investment will be worth $3964.93 in 5 years

The consecutive age is 6 and 7 and Malik is 6 years old.

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

let their Consecutive age be x, x+1

So, x(x+ 1)= 42

x²+ x - 42 = 0

x² + 7x- 6x - 42=0

x( x+ 7)- 6 ( x+ 7)= 0

(x+ 7)( x-6)= 0

x = 6, -7

Hence, the consecutive age is 6 and 7.

Yannick paid $9.25 as sales tax on the bicycle.

Here, we are given that Yannick bought a bicycle and paid $194.25 for it, including tax.

Let the cost of the bicycle without tax be x

We are given that the rate of sales tax is 5%

Thus, the amount of tax on bicycle will be-

5% of x

= (5/100)*x

= 0.05x

Thus, we can form an equation as follows-

x + 0.05x = 194.25

1.05x = 194.25

x = 194.25/ 1.05

x = 185

Thus, the cost of bicycle without tax is 185

Therefore, the tax paid will be-

0.05x

= 0.05*185

= 9.25

Thus, Yannick paid $9.25 as sales tax on the bicycle.

The radius of the pond is found to be 17.32m.

What is angle of elevation?

The angle of elevation is the angle created between the line of sight and the horizontal. The angle created is an angle of elevation if the line of sight is upward from the horizontal line.

Given;

Length of the pole above= 30m

Angle of elevation = 60°

From the given information we can draw the diagram as the pole becomes the opposite of the angle of elevation and radius becomes the base.

Therefore,

Opposite / Base = tan 60°

=> base = 30 / √3

=> base = 17.32m

We have a relationship between temperature and chirp rate, such that the input in this case is the temperature.

We define a relation as an operator that maps elements from one set (the domain, set of the inputs) into elements of another set (the range, set of the outputs).

Particularly, the relations are written as:

x → y

Where y is the output and x is the input.

In this case, we have two pairs of the relation, these are:

Line DC and Line AC both have the same measure of 28ft.

The angles are the sum of the same measures.

Answer:

A. x = 11

Step-by-step explanation:

so, the angle D corresponds to angle T.

therefore, the side BD corresponds to RT.

and CD to ST.

since both triangles are similar, they must have the same angles, and all corresponding sides and other lengths must have the same scaling factor.

so,

RT × f = BD

and the same f must then apply to

ST × f = CD

21 × f = 98

f = 98/21 = 14/3 = 4.666666666...

33 × 14/3 = 15x - 11

11 × 14 = 15x - 11

154 = 15x - 11

Line AB is always skew to line CD as the two lines are in different planes.

Line AB will sometimes intersect line EF as the two planes intersect at some point.

We know that a plane represents a 2 dimensional surface in a 3 dimensional area.

Now it is given that planes x and y are parallel to each other, therefore they will never intersect at any place.

Now two separate lines on these two separate planes will also not intersect with each other as  they are on different planes and the ploanes do not meet.

Hence Line AB is always skew to line CD as the two lines are in different planes.

Again for Line AB it will intersect EF as the plane z intersects the plane x on which the line AB is located.

We know that the lines can still be skew lines but there is a possibility that they will meet.

Hence Line AB will sometimes intersect line EF as the two planes intersect at some point.

The solution of the inequality in the variable x <0.

Any monotonically rising function can, by definition, be applied to both sides of an inequality without violating the asymmetry connection (provided that both expressions are in the domain of that function). The inequality relation is flipped when a monotonically decreasing function is applied to both sides of an inequality. In the criteria for the basic inverse and the multiplicative inverse for positive values, a monotonically decaying function is utilized.

The given inequality is

4x + 2 <2

subtracting 2 from both sides

4x+2-2<2-2

or,4x < 0

or, x < 0

If the inequality is strict (a< b, a > b) and the function is strictly monotonic, the inequality remains strict. If only one of the preceding conditions is met, the ensuing imbalance does not exist. Indeed, the rules for addition and multiplicative exponentiation use a monotonically decreasing function.

Hence the solution of the inequality in the variable x <0.

Answer:

x ≈ - 3.9 , x ≈ 5.9

Step-by-step explanation:

x² - 2x - 23 = 0 ( add 23 to both sides )

x² - 2x = 23

using the method of completing the square

add ( half the coefficient of the x- term)² to both sides

x² + 2(- 1)x + 1 = 23 + 1

(x - 1)² = 24 ( take square root of both sides )

x - 1 = ± [tex]\sqrt{24}[/tex] ( add 1 to both sides )

x = 1 ± [tex]\sqrt{24}[/tex]

then

x = 1 - [tex]\sqrt{24}[/tex] ≈ - 3.9 ( to 1 dec. place )

x = 1 + [tex]\sqrt{24}[/tex] ≈ 5.9 ( to 1 dec. place )

The information that is not needed to determine the total bill after tax is is the tax was 7%.

The total bill is $11.

The total bill paid is the sum of the cost of the meal, tax and the tip paid. The tip and tax would increase in the total amount that is paid by the customers.

Tax is a compulsory amount that is levied by the government on certain goods and services.

Percentage is the fraction of an amount expressed as a number out of hundred. To convert a number from percentage to a number, divide the percentage by 100.

Tax paid = 10% x total bill

$1.10 = 0.1 x b

1.10 = 0.1b

b = 1.10 / 0.1
