Rhea saved three parts of her salary and spent one part of t to rent an apartment. she spent $765 on rent, calculate Rhea's earnings.

2x+2y=6

5x+2y =4

Multiply eq 1 by 5 and equation 2 by -2

10x+10y = 30

-10x - 4y = -8

Now adding we get

6y = 22

Divide by 2

3Y =11

Answer:

840 visitors

Step-by-step explanation:

Well to find how much 12 biscuits cost, you must first find how much each biscuit costs. Therefore, you divide 80p by 2, and get 40p. Then multiply 40p by 12 (the total amount of biscuit). You get the answer, which is 480p.

Answer:

See two different cases, below:

Step-by-step explanation:

You cannot "solve" w-w*2+-2w*2, because this is not an equation.  Rather, you want to simplify w-w*2+-2w*2 by combining like terms.  You have w  -  2w   -  4w, or -5 w.

If, however, you meant "exponentiation" by " * "  then you have   w^1 - w^2 - 2w^2, which in turn equals w - 3w^2, or, in descending order by powers of w, -3w^2 + W.

Step-by-step explanation:

The answer is 44 because 66-22=44, 44+22=66 44 is twice of 22

So the corcumference is equal to the diameter tiems pi.

Youre given the diameter, so just multiply it by pi.

The answer is 43pi.

The circumference of a circle with a diameter of 43 cm can be calculated using the formula C = πd. Substituting 43 for d, the exact circumference in terms of pi is 43π cm.

The circumference of a circle is determined by the formula C = πd, where C is the circumference, d is the diameter of the circle, and π (Pi) is a mathematical constant whose approximate value is 3.14. If we plug the given diameter of 43 cm into the formula, we get C = π * 43. Thus, the exact circumference in terms of pi is 43π cm.

Answer:

Original price of the ticket was $57.

Step-by-step explanation:

Four friends buy tickets for two shows.

Let the price of a ticket was $c

Then cost of 4 tickets = $4c

They use a coupon to get the discount = $5 on each ticket

So total discount on 4 tickets = 4×5 = $20

Cost of the tickets after discount = 4c - 20

Cost of the tickets for two consecutive nights = 2(4c - 20)

If they paid total amount = $416 for 8 tickets

Then the equation will be 2(4c - 20) = 416

Now we can solve this equation to get the original price of the ticket.

2(4c - 20) = 416

4c - 20 = 208

4c = 208 + 20

4c = 228

c = [tex]\frac{228}{4}[/tex]

c = $57

Therefore, original price of a ticket was $57.

Answer: 15 cm

Step-by-step explanation:

Given : The total height of all three of Thumbelina’s sisters is 60 cm.

The heights of the three sisters are in the ratio 4:3:5 .

Let the heights of the three sisters are 4x , 3x and 5x.

According to the question , we have the following equation :-

[tex]4x+3x+5x=60\\\\\Rightarrow\ 12x=60\\\\\Rightarrow\ x=\dfrac{60}{12}=5[/tex]

Now, the height of the shortest sister will be :-

[tex]3x=3(5)=15\ cm[/tex]

Hence, the height of the shortest sister = 15 cm

This kind of problems are solved using Bernoulli's distribution. Everytime you have a win/lose scenario, and you know the probability [tex] p[/tex] of winning, and you want [tex]k[/tex] successes over [tex]n[/tex] trials, you have the following probability:

[tex]\displaystyle P(k\text{ successes over }n\text{ trials}) = \binom{n}{k}p^k(1-p)^{n-k} [/tex]

You want the probability of having at least three successes, i.e. you are interested in the cases k=3 and k=4. The corresponding probabilities are

[tex]\displaystyle P(3 \text{ successes}) = \binom{4}{3}0.6^3 \cdot 0.4 = 4\cdot 0.216 \cdot 0.4 = 0.3456[/tex]

[tex]\displaystyle P(4 \text{ successes}) = \binom{4}{4}0.6^4 = 0.1296 [/tex]

So, the total probability is [tex] 0.3456+0.1296 = 0.4752[/tex]

Solution :

Given a right triangle with hypotenuse 85 and legs 84 and y.

Use Pythagoras theorem, to find the length of the leg y of the right triangle.

According to Pythagoras theorem,

[tex](hypotenuse)^{2} = leg_{1}^{2}+leg_{2}^{2}[/tex]

As given in the question,

[tex]hypotenuse = 85 \\\\leg_{1} = 84\\\\leg_{2} = y[/tex]

Put these values,

[tex]\Rightarrow 85^{2}=84^{2} +y^{2} \\\\\Rightarrow y^{2}=85^{2}-84^{2}\\\\\Rightarrow y =\sqrt{85^{2}-84^{2}} \\\\\Rightarrow y =\sqrt{169}\\\\\Rightarrow y =13[/tex]

Hence, the length of leg y =13.

Answer:

The length of leg y=13

Answer:

The graph in the attached figure

Step-by-step explanation:

Let

x-------> the set of numbers that represent the solution of the situation

we know that

The expression " At least [tex]-6[/tex] " represent the inequality

[tex]x\geq -6[/tex] -----> all real numbers greater than or equal to  [tex]-6[/tex]

The expression " At most [tex]3[/tex] " represent the inequality

[tex]x\leq 3[/tex] -----> all real numbers less than or equal to  [tex]3[/tex]

The solution of the situation is equal to the interval-------> [tex][-6,3][/tex]

see the attached figure

Answer: Consider a quadrilateral ABCD such that AC ans BD are the two diagonals of ABCD.

With reference to figure 1 .

In triangle ABC and triangle ADC  ,by using triangle inequality we have

AB +BC > AC .......(1)

and AD + CD >AC......(2)

adding (1) and (2) we have

AB+ BC+CD+AD>2AC....(3)

Similarly we get for diagonal BD

AB+BC+CD+AD>2BD....(4)

Adding (3) and (4) we get

2(AB+BC+CD+AD)> 2(AC+BD)

⇒(AB+BC+CD+AD)> AC+BD where (AB+BC+CD+AD) = perimeter of quadrilateral.

Hence, the sum of the length of the diagonals of a quadrilateral is less than the perimeter.

Now 2 diagonal divides quadrilateral into 4 quadrilaterals  

Therefore AO+OD>AD

OD+OC>CD

OC+OB>BC

And OA+OB>AB

Adding all these conclude that

2(AC+BD)>AB+BC+CD+AD

⇒AC+BD>1/2(AB+BC+CD+AD)  where (AB+BC+CD+AD) = perimeter of quadrilateral.

Hence,the sum of the length of the diagonals is greater than the half of the perimeter of this quadrilateral.

Now consider a triangle ABC  as given in figure (2)

As we now,the sum of two sides of a triangle is greater than twice the median bisecting the third side.

Therefore AB+BC>2BE

Similarly,

AB+AC>2AD

BC+AC>2CF

By adding all these we get ,

2(AB+BC+CA)>2(AD+CF)

⇒AB+BC+CA>AD+CF

Hence, the sum of the lengths of the three medians in a triangle is smaller than the perimeter of the triangle.

Distributive property

-8*4=-32          -8*9x=-72x

-32-72x=7(-2-11x)

7(-2)=-14      7(-11x)=-77x

-32-72x=-14-77x

Combine Like Terms

-32+14=-18       -77x+72x=-5x

-18=-5x

Answer:

From the comments below we see the missing part of the question is "in how many days will the ant farm consume 3 apples?"

The answer is 18.

Step-by-step explanation:

We will use a proportion to solve this.  It takes 3 days to consume 1/2 of an apple; this gives us the ratio

3/0.5

We want to know how many days, x, it will take to consume 3 apples; this gives us the ratio

x/3

Together this gives us the proportion

3/0.5 = x/3

Cross multiply:

3(3) = 0.5(x)

9 = 0.5x

Divide both sides by 0.5:

9/0.5 = 0.5x/0.5

18 = x

The ant farm will take 18 days to consume 3 apples.

Given that,

According to above information, calculation of data are as follows,

[tex]X = (3 \div 0.5) \times 3\\\\X = 6 \times 3[/tex]

X = 18

So, Total number of days required is 18 days.

Answer:

Mean = 7.5, median = 5, mode = 4

Step-by-step explanation:

The value of s from the given equation is -1.5.

The given equation is 0.5s+1=7+4.5s.

We solve the given equation for s.

Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign. It shows the relationship of equality between the expression written on the left side with the expression written on the right side. In every equation in math, we have, L.H.S = R.H.S (left hand side = right hand side). Equations can be solved to find the value of an unknown variable representing an unknown quantity.

Now, the given equation can be solved as follows:

0.5s+1=7+4.5s

⇒0.5s-4.5s=7-1

⇒-4s=6

⇒s=-6/4

⇒s=-1.5

Therefore, the value of s is -1.5.
