Given is the table that shows the cost of renting a sound system for a concert. Isabel rents a sound system at 1 p.m. and plans to return it before 4 p.m.

The total number of hours for which she will rent the sound system is -

{h} = 4 - 1 = 3 hours

{h} = 3 hours

Now, for 3 hours, the given inequality is -

2 < x ≤ 3

We can write the cost as $60.

If she is 30 minutes late, then she will pay $72.

Therefore, we can conclude that -

[tex]\frac{x}{2}-\frac{2}{x+1}=1[/tex]

We have 2 denominators that we need to get rid of. Whenever there are the denominators, all we have to do is multiply all whole equation with the denominators.

Our denominators are both 2 and x+1. Therefore, we multiply the whole equation by 2(x+1)

[tex]\frac{x}{2}[2(x+1)]-\frac{2}{x+1}[2(x+1)] = 1[2(x+1)][/tex]

Then shorten the fractions.

[tex]\frac{x}{2}[2(x+1)]-\frac{2}{x+1}[2(x+1)] = 1[2(x+1)]\\x(x+1)-2(2)=1(2x+2)[/tex]

Distribute in all.

[tex]x^2+x-4=2x+2[/tex]

We should get like this. Because the polynomial is 2-degree, I'd suggest you to move all terms to one place. Therefore, moving 2x+2 to another side and subtract.

[tex]x^2+x-4-2x-2=0\\x^2-x-6=0\\[/tex]

We are almost there. All we have to do is, solving for x by factoring. (Although there are more than just factoring but factoring this polynomial is faster.)

[tex](x-3)(x+2)=0\\x=3,-2[/tex]

The area of the given doormat is 0.4 meter square.

Here, we are given that Sammy has a rectangular doormat. The dimensions of the doormat are given as follows-

The length of the doormat is = 4/5 meters

and the breadth of the doormat is = 1/2 meters

The area of a rectangular figure is given by the formula as follows-

Area of a rectangle = length × breadth

Let the area of the rectangular doormat be A

Thus, in this case, we have-

A = 4/5 × 1/2

A = 4/ 10

A = 2/5

Now, converting the area obtained into a decimal number we get-

A = 0.4

Thus, the area of the given doormat is 0.4 meter square.

Answer:

Y= 30

X= 0.75

Step-by-step explanation:

If the first Y was 1,200 and X was 30, then that means every time your divide Y by 40, you will get your X. It's the exact opposite if you want to find Y.

So you want to divide your Y, which is 30, by 40. Once who find your answer, you should have gotten 0.75 for X.

Why divide by 40? Good question. You divide by 40 because if you multiply your X example Y= 1,200, X= 30, you will get 30x40 which is 1,200. Do it the other way around divide 1,200 by 40, you get 30.

All in all your answer should be X= 0.75. If not tell me.

The tax rate is 4.50% if Julius earns $47,800 a year working for delivery service. He is single and pays $2,152.60 in state income tax each year.

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

It is given that:

Julius earns $47,800 a year working for delivery service. He is single and pays $2,152.60 in state income tax each year.

To find the tax rate:

tax rate = (2152.60/47800)×100

tax rate = (0.045)×100

tax rate = 4.50%

Thus, the tax rate is 4.50% if Julius earns $47,800 a year working for delivery service. He is single and pays $2,152.60 in state income tax each year.

Answer: after eliminating B due to Hare Method, A will have a total of 67 VOTES

Step-by-step explanation:

Given that;

The results are

ABC : 41

BAC : 26

CAB : 42

NOW

A>B>C = 41 ⇒ A has 41 votes

B>A>C = 26 ⇒ B has 26 votes

C>A>B = 42 ⇒ C has 42 votes

According to Hare method, least votes gainers will be eliminated and once eliminated, his/her/its votes will be transferred to the next choice of person/thing.

based on the question; B will be eliminated

so we have;

A>B>C = 41 ⇒ A has 41 votes

B>A>C = 26 ⇒ B has 26 votes

we eliminate B, the votes are transferred to the next (A)

A>C = 26 ⇒ A has 26 votes

C>A>B = 42 ⇒ C has 42 votes

SO in total

A votes = 41 + 26 = 67 VOTES

Therefore after eliminating B due to Hare Method, A will have a total of 67 VOTES

After eliminating B due to Hare Method, A will have a total of 67 votes

We have given that,the results are

ABC : 41

BAC : 26

CAB : 42

A>B>C = 41 ⇒ A has 41 votes

B>A>C = 26 ⇒ B has 26 votes

C>A>B = 42 ⇒ C has 42 votes

The Hare method is least votes gainers will be eliminated and once eliminated,The  votes will be transferred to the next choice of person/thing.

From the given question we have B will be eliminated

Therefore  we have

A>B>C = 41 ⇒ A has 41 votes

B>A>C = 26 ⇒ B has 26 votes

We eliminate B, the votes are transferred to the next (A)

A>C = 26 ⇒ A has 26 votes

C>A>B = 42 ⇒ C has 42 votes

Therefore the total votes are

A votes = 41 + 26 = 67 votes

Therefore after eliminating B due to Hare Method, A will have a total of 67 votes.

Answer:

x = 55

y = 55

z = 70

Step-by-step explanation:

x + 125 is a straight line, 180⁰ x+125=180 x=55⁰

since this is an isosceles triangle, x = z

and the sum of all angles in any triangle is 180⁰

55+55+y=180⁰

y = 70⁰

Answer:

x=55º, y=70º, z=55º

Step-by-step explanation:

We have that xº = 180º - 125º = 55º

As it is an isosceles triangle, we have xº = zº = 55º

Therefore, yº = 180º - (xº + zº) = 180º - (55º + 55º) = 180º - 110º = 70º

Given:

LCM(a,b) = 90 and GCD(a,b) = 3.

b is three more than a.

To find:

The values of a and b.

Solution:

We have,

LCM(a,b) = 90

GCD(a,b) = HCF(a,b) = 3

According to the question,

[tex]b=a+3[/tex]

If a and b are two positive integers, then

[tex]a\times b=HCF(a,b)\times LCM(a,b)[/tex]

[tex]a\times (a+3)=3\times 90[/tex]

[tex]a^2+3a=270[/tex]

[tex]a^2+3a-270=0[/tex]

Splitting the middle terms, we get

[tex]a^2+18a-15a-270=0[/tex]

[tex]a(a+18)-15(a+18)=0[/tex]

[tex](a+18)(a-15)=0[/tex]

Using zero product property, we get

[tex]a+18=0[/tex] and [tex]a-15=0[/tex]

[tex]a=-18[/tex] and [tex]a=15[/tex]

a is a positive integer so it cannot be negative. So, a=15.

Now,

[tex]b=a+3[/tex]

[tex]b=15+3[/tex]

[tex]b=18[/tex]

Therefore, the value of a is 15 and the value of b is 18.

The x-axis is equivalent to x = 4, x + y = 0, x = y, and y = 4, and the value of the x-axis is y = 0.

Expressions that are equivalent do the same thing even when they have distinct appearances.. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value(s) for the variable(s)

Rhombus

A rhombus is a special case of a parallelogram. In a rhombus, opposite sides are parallel and the opposite angles are equal. The rhombus is also called a diamond or rhombus diamond.

It is given in the question that there is a rhombus ABCD with ∠ DAC = 58 degrees.

We have to find the angle x or  ∠ ADB.

We know the property that the diagonals of the rhombus perpendicularly bisect each other.

Hence, the rhombus is divided into 4 right triangles.

Hence,

∠DAC +  ∠ADB = 180 - 90  = 90 degrees

58 + x = 90 degrees

x = 90 - 58

x = 32 degrees.
