The number of gallons of paints that will be made if 28 drops is used is 20 gallons

A rate is a ratio that compares two different quantities which have different units. For example, if we say John types 50 words in a minute, then his rate of typing is 50 words per minute. The word "per" gives a clue that we are dealing with a rate.

The total number of drops used to make 5 gallons is 7drops, i.e 4+3=7

this means to make 1 gallon 5/7 drops of color will be used

Therefore for 28 drops , 5/7×20 gallons will be made

= 20gallons

Therefore the gallons made with 28drops is 20gallons.

In the triangle LMN angle N is 76 degree.

Given,

In the question:

There is two isosceles triangle in the figure:

Triangle JKL and Triangle LMN

Angle J = 64 degree

To find the angle Angle N

Now, According to the question:

The triangle is isosceles.

<J = 64 degrees

All triangles have 180

<JLK = 180 - 64 - 64

Angle JLK = 52degree.

Angle JLK = MLN  = 52 degree (Vertical opposite angle )

M is the left over from the 2 equal angles.

N = 180 - <M - < MLN                      

N = 180 - 52 - 52

N = 76 degree

Hence, In the triangle LMN angle N is 76 degree.

Answer:  360,000

Reason:

Think of 360 as 360.0

We move the decimal point 3 spots to the right to get to 360,000.0 or simply 360,000; this movement of 3 to the right is directly because of the exponent over the 10.

The 10^3 represents "thousand", so "360 x 10^3" is "360 thousand" = 360,000.

You have to calculate the probability of obtaining an odd number after rolling the die and obtaining tail after tossing a coin, symbolically:

Where

"O" represents the event " rolling an odd number"

"T" represents the event "tossing a coin and obtaining tail"

The events are independent, which means that the intersection between both events is equal to the product of the individual probability of each event:

So, first, we have to calculate the probabilities of "rolling an odd number" P(O) and "tossing a coin and obtaining tail" P(T)

-The die is six-sided and numbered from 1 to 6, assuming that each possible outcome has the same probability, we can calculate the probability of rolling one number (N) as follows:

The possible outcomes when you roll a die are {1, 2, 3, 4, 5, 6}

Out of these six numbers, three are odd numbers {1, 3, 5}, this is the number of favorable outcomes of the event "O", and the probability can be calculated as follows:

So, the probability of rolling an odd number is P(O)=1/2

-When you toss a coin, there are two possible outcomes: "Head" and "Tail", assuming that both outcomes are equally possible.

For the event "toss a coin and obtain tail" there is only one favorable outcome out of the two possible ones, so the probability can be calculated as:

The probability of tossing a coin and obtaining a tail is P(T)=1/2

Once calculated the individual probabilities you can determine the asked probability:

Answer: ∠WZY=150°

Step-by-step explanation:

Analysis :

ΔWXY is an isosceles triangle

perpendicular to WX intersecting:

XY at A

∠XWA = 21°

∠WXA = 90°-21° = 69°

Now, ΔXYZ is equilateral,

∠XYZ = ∠YXZ = 60°

Then,

∠WXZ = ∠WXA - ∠YXZ

= 69°-60°

= 9°

Since the angles of a triangle = 180°

∠WZY = ∠WZX = 180° - ∠XWA - ∠WXZ

= 180° - 21° - 9°

= 150°

Answer:

Step-by-step explanation:

To find the nth term of a quadratic sequence, we need to determine the quadratic function that generates the sequence.

Given quadratic sequence:

4, 7, 12, 19, 28, ...

Begin by calculating the first differences between consecutive terms:

[tex]4 \underset{+3}{\longrightarrow}7 \underset{+5}{\longrightarrow} 12\underset{+7}{\longrightarrow} 19\underset{+9}{\longrightarrow} 28[/tex]

As the first differences are not the same, we need to calculate the second differences (the differences between the first differences):

[tex]3\underset{+2}{\longrightarrow} 5 \underset{+2}{\longrightarrow} 7\underset{+2}{\longrightarrow}9[/tex]

As the second differences are the same, the sequence is quadratic and will contain an n² term.

The coefficient of the n² term is half of the second difference.

As the second difference is 2, the coefficient of the n² term is 1.

Now we need to compare n² with the given sequence (where n is the position of the term in the sequence).

[tex]\begin{array}{|c|c|c|c|c|c|}\cline{1-6}n&1&2&3&4&5\\\cline{1-6}n^2&1&4&9&16&25\\\cline{1-6}\sf operation&+3&+3&+3&+3&+3\\\cline{1-6}\sf sequence&4&7&12&19&28\\\cline{1-6}\end{array}[/tex]

We can clearly see that the algebraic operation that takes n² to the terms of the sequence is add 3.

Therefore, the expression to find the the nth term of the given quadratic sequence is:

[tex]\boxed{a_n=n^2 +3}[/tex]

The average rate of change over the interval x = 3 and x = 7 is 30

The average rate of change of a function, graph, table or ordered pair is simply the slope of the relation

The equation is given as

g(x) = 2ˣ - 1

The interval is given as:

x = 3 and x = 7

Start by calculating g(3) and g(7)

So, we have

g(3) = 2³ - 1 = 7

g(7) = 2⁷ - 1 = 127

So, the average rate over these intervals is calculated as:

Average rate = [g(b) - g(a)]/[b - a]

This gives

Average rate = [g(7) - g(3)]/[7 - 3]

Substitute known values

Average rate = [127 - 7]/[7 - 3]

Simplify

Average rate = 120/4

Average rate = 30

Hence, the average rate of change is 30

Current price of go-kart = $2,589

Price of go-kart next month = $2,119

If Rafael decides to buy the go-kart next month,

He will save $2,589 - $2,119 = $470

By definition of estimation

Estimation is an approximate calculation or judgment of the value, number, quantity, or extent of something

Approximating to the nearest hundred

$470 = $500

Therefore, Rafael will save an estimate of $500 if he wants to buy the go-kart next month

Since f is the number of female cousins and the number of male cousins is 4 less than the number of female cousins, we can write the following expression to represent the number of male cousins:

For example, if the number of female cousins is 7, we can use this value (f = 7) in the expression above to find the number of male cousins:

So if the number of female cousins is 7, the number of male cousins is 3.

Therefore the expression for the number of boy cousins is f - 4.
