Answer 1

We need to know about

linear equation

to solve this problem. (a) The equation that will allow Robel to calculate what his total cost will be is 52+94n (b) Robal's total cost if he decides to stay 3 nights is $334

A

linear equation

is one that has

one or two variables

in it, the variables in a linear equation are linearly related to each other which means that the graph of such an equation is a straight line.

In part (a) it is said that Robel is charged $52 as a one time fee and the

cost per night

is $94, let us consider the

total cost to be t

and the

number of nights he stays be n,

then the equation for the total cost will be

t=52+94n

In part (b) we have to find out the total cost if he stays 3 nights, which means n=3,

substituting the value of n

in the equation for total cost

t=52+94x3=334

Therefore we found out that the

equation for Robel's total cost

is 52+94n and the total cost if he stays for 3 nights is $334.

How much interest would 2000 earn, with simple interest, in two years at the rate of 1.2%?

Answers

The simple interest, in two years at the rate of 1.2% is 880

In this case, we must calculate how much interest 2000 would earn compounded yearly over two years at a rate of 1.2.

I = 880 in interest earned

Annually, the system may be evaluated in terms of simple interest.

A = P(rt) for the first year, where r = 1.2 and t = 1.

Therefore;

A = 2000(1.2×1).

A = 2400.

As a result, the revised Principal amount for the second year is 2400.

As a result, A' = 2400 (1.21).

A' = 2880.

As a result, the sum owing after two years is 2880.

However, because the initial principal is $2,000,

The interest is defined as I = A' - P, or I = 2880 - 2000.

I = 880 as a result of interest.

Simple interest is computed as S.I. = P R T, where P = Principal, R = Annual Rate of Interest in %, and T = Time, commonly expressed as the number of years. The interest rate is expressed as a percentage r% and is written as r/100.

The principle is the money borrowed from the bank or invested at the outset. P represents the principal.

Rate: The rate of interest at which the principle amount is handed to someone for a specific period of time; the rate of interest can be 5%, 10%, or 13%, for example. R represents the interest rate.

Time is the length of time for which the primary amount is supplied to someone. T represents time.

he equation y equals 4 times 6 to the power of t shows the number of infected people from an outbreak of the measles. The variable y represents the number of infected people, and t represents time in weeks.

In how many weeks will the number of infected people reach 568?

Answers

The number of infected people will reach 568 in approximately 4 weeks

Linear equation and function

Exponential equations are inverse of logarithmic equation and are represented by the equation below:

y = ab^x

where

a is the base value and x is the exponent

Given the equation that shows the number of infected people from an outbreak of the measles as:

y = 4(6)^t

If the number of infected people reach 568, hence;

568 = 4(6)^t

568/4 = 4(6)^t/4

6^t = 568/4

6^t = 142

Take the natural logarithm of both sides

ln(6^t) = ln142

t = ln142/ln6

t = 4.37

b. The slope of the line perpendicular to  y = 3/4x - 1 is: -4/3.

What is the Slope of Lines that are Perpendicular and Lines that are Parallel?

If two lines are parallel to each other, they will have the same slope value. On the other hand, if the two lines are perpendicular to each other, they will have slopes that are negative reciprocals of each other.

Thus, given the equation, y = 3/4x - 1, the slope of this line is 3/4.

The negative reciprocal of 3/4 is -4/3.

Therefore, we can conclude that:

3. C. x = 6, y = 3.

4. C. [tex]x = 2\sqrt{5}, y = \frac{2\sqrt{15}}{3}[/tex]

What are the relations in a right triangle?

There are three relations in a right triangle, given as follows:

The sine of an angle of the triangle is given by the length of the opposite side to the angle divided by the length of the hypotenuse.The cosine of an angle of the triangle is given by the length of the adjacent side to the angle divided by the length of the hypotenuse.The tangent of an angle of the triangle  is given by the length of the opposite side to the angle divided by the length of the adjacent side to the angle.

For the first triangle, we have that:

tan(45º) = 7/y

1 = 7/y

y = 7.

Applying the Pythagorean Theorem:

x² = 7² + 7²

x = sqrt(2 x 49)

[tex]x = 7\sqrt{2}[/tex]

Hence the correct option is:

D. [tex]x = 7\sqrt{2}, y = 7[/tex]

For the second triangle, we have that:

tan(45º) = y/3

1 = y/3

y = 3.

Applying the Pythagorean Theorem:

x² = 3² + 3²

x = sqrt(2 x 9)

[tex]x = 3\sqrt{2}[/tex]

Hence the correct option is:

B. [tex]x = 3\sqrt{2}, y = 2[/tex].

For the third triangle, we have that:

[tex]\tan{30^\circ} = \frac{y}{3\sqrt{3}}[/tex]

[tex]\frac{\sqrt{3}}{3} = \frac{y}{3\sqrt{3}}[/tex]

y = 3 x 3/3

y = 3.

Then:

[tex]\sin{30^\circ} = \frac{y}{x}[/tex]

0.5 = 3/x

x = 6.

Hence the correct option is:

C. x = 6, y = 3.

For the fourth triangle, we have that:

[tex]\sin{30^\circ} = \frac{y}{\frac{4\sqrt{15}}{3}}[/tex]

[tex]0.5 = \frac{y}{\frac{4\sqrt{15}}{3}}[/tex]

[tex]y = \frac{2\sqrt{15}}{3}[/tex]

[tex]\cos{30^\circ} = \frac{x}{\frac{4\sqrt{15}}{3}}[/tex]

[tex]\frac{\sqrt{3}}{{2}} = \frac{x}{\frac{4\sqrt{15}}{3}}[/tex]

[tex]x = 2\sqrt{5}[/tex]

Hence the correct option is:

Answer:

There are 63 M&M's in the bag when all of them are added together.

16 out of 63 (16/63) were yellow.

5 out of 21 (5/21) were green. This answer is simplified. The original is 15/63.

1 out of 3 (1/3) were brown. This answer is simplified. The original is 21/63.

11 out of 63 (11/63) were red.

Tip:

To find the fraction of something, put the total on the bottom and the wanted portion on the top.

Example: 5 yellow and 10 red birds were in a cage. Which fraction were yellow?

We put the total of birds (5+10 = 15) on the bottom and the portion wanted ("5 yellow") on the top. The fraction is 5 out of 15 (5/15). This fraction can be simplified because 5 goes into 15 three times (5 x 3 = 15), so divide the fraction 5/15 by 3 to get 1/3. (5 goes into 5 one time.)

Given a table of supply and demand at each price point, you are asked for the equilibrium price if the demand numbers are decreased by 0.5 million.

Equilibrium price

The equilibrium price is the price at which the quantity demanded is equal to the quantity supplied.

For the given table, we see that a price of $14 thousands will result in both demand and supply being 2.00 millions per year. That is the equilibrium price before any adjustment to the table is made.

The problem statement is telling you to use a table that has all of the demand values decreased by 0.5 million. That makes the demand column read ...

  2.25, 2.00, 1.75, 1.50, 1.25, 1.00, 0.75

This new column of reduced demand values matches the numbers in the supply column when they are both 1.75 million per year. That match occurs on the line with price $12 thousand.

The new equilibrium price is $12 thousand.

2 1/6 = (2×6 + 1) = 13/6 days

To add and then subtract them directly, we need to bring all fractions to the same denominator.

we have to multiply each fraction by a fitting n/n factor to bring the denominators to 12

67/4 = 67/4 × 3/3 = 201/12

7/4 = 7/4 × 3/3 = 21/12

14/3 = 14/3 × 4/4 = 56/12

13/6 = 13/6 × 2/2 = 26/12

Thus the remaining vacation time will be

201/12 - 21/12 - 56/12 - 26/12 = 98/12 = 49/6

49/6 = 8 and remainder 1 = (8×6 + 1)/6 = 8 1/6 days

Hence, Bill Murray has 16 3/4 days in total of vacation per year.  Bill entitled to  8 1/6 days more vacation time.

Show that the set {-1, 0, 1} is closed under multiplication

Answers

The statement that the set {-1, 0, 1} is closed under multiplication, is true and can be proven.

As per the question statement, we are provided with a set {-1, 0, 1}.

We are required to determine if the above mentioned set is closed under multiplication or not.

To solve this question, we simply need to verify if the products of every distinct combination of 2 elements from the concerned set, belongs to the set itself or not, i.e., if we take any two elements "x" and "y", say, from the set "Z", then, [(x*y) ∈ Z].

Here, [tex][(-1)*0]=0[/tex], i.e., belongs to set {-1, 0, 1}.

[tex][(-1)*1]=(-1)[/tex] i.e., also belongs to set {-1, 0, 1}.

Finally, [tex](0*1)=0[/tex] i.e., also belongs to set {-1, 0, 1}.

Since,  the products of every distinct combination of 2 elements from the concerned set, belongs to the set itself, the statement that the set

{-1, 0, 1} is closed under multiplication, is true and proven.

Set closed under multiplication: This means that, for any set say "Z", the product of distinct combinations of it's elements, say (x*y) belongs to Z, such that [(x, y) ∈ Z].

Yossi used to have a square garage with ft of floor space. recently built an addition to it. The garage is still a​ square, but now it has​ 50% more floor space. What was the length of one side of the garage​ originally? What is the length of one side of the garage​ now? What was the percent increase in the length of one​ side?

Answers

The length of one side of the garage originally is 18.17 feet.

The length of one side of the garage now is 22.25 feet.

The percent increase is 22.4%.

What is the increase in the length of the garage?

A square is a quadrilateral with four sides of equal length. A square has two diagonals of equal length that intersect at right angles.

Given the area of a square, the length of one side can be determined by calculating the square root of the area.

Area of the square = length²

Length of one side of the square = √area

√330 = 18.17 ft

Area of the garage after it was increased : (1 + percentage increase) x initial area

(1 + 0.5) x 330

1.5 x 330 = 495 feet²

Length of the side of the garage after it is increased = √495 = 22.25 feet

The percentage increase = (22.25 / 18.17) - 1 = 0.224 = 22.4%

Writing an Inequality

From the question, we are to write and solve an inequality which can be used to determine the number of visits Emma can make to earn her first fee movie ticket

From the given information,

"She receives 30 rewards points just for signing up"

and

"She earns 7.5 points for each visit to the movie theater"

If she visits the movie theater v number of times,

Then,

She would earn

30 + 7.5v points

Also,

She needs at least 135 points for a free movie ticket.

Thus,

The inequality that could be used to determine the number of visits, v, to earn a free movies ticket is

30 + 7.5v ≤ 135

Solving the inequality

30 + 7.5v ≤ 135

Subtract 30 from both sides

30 - 30 + 7.5v ≤ 135 - 30

7.5v ≤ 105

v ≤ 105/7.5

v ≤ 14

Hence, the number of visits Emma could make to earn her first free movie ticket is 14
