Explanation:

↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓

[tex]2(\frac{5}{3}+\frac{3}{4})-\frac{4}{3}[/tex]

[tex]2(\frac{5}{3}+\frac{3}{4})=\frac{29}{6}[/tex]

[tex]\frac{29}{6}-\frac{4}{3}[/tex]

You had to used least common multiple of 6 and 3.

Prime factorization of 6: 1, 2, 3, 6

3*2=6

Prime factorization of 3: 1, 3

1*3=3

Then multiply by the number

3*2=6

You can also multiply by each numerator by the same amount needed to multiply its corresponding denominator to turn it into the least common multiple is 6.

Then you had to used 4/3 multiply by the denominator and numerator by 2.

[tex]\frac{4}{3}=\frac{4*2}{3*2}=\frac{8}{6}[/tex]

[tex]\frac{29}{6}-\frac{8}{6}[/tex]

Since the denominators are equal, it combine by the fractions.

[tex]\frac{29-8}{6}[/tex]

Then you can subtract by the numbers.

[tex]29-8=21[/tex]

[tex]\frac{21}{6}[/tex]

You had to cancel by the common factor of 3.

[tex]=\frac{7}{2}[/tex]

The coordinates of the vertices of △PQR are P(1, 4) , Q(2, 2) , and R(−2, 1) . The coordinates of the vertices of △P′Q′R′ are P′(−1, 4) , Q′(−2, 2) , and R′(2, 1) .


Which statement correctly describes the relationship between △PQR and △P′Q′R′ ?

A) △PQR is congruent to △P′Q′R′ because you can map △PQR to △P′Q′R′ using a reflection across the x-axis, which is a rigid motion.

B) △PQR is congruent to △P′Q′R′ because you can map △PQR to △P′Q′R′ using a reflection across the y-axis, which is a rigid motion.

C) △PQR is congruent to △P′Q′R′ because you can map △PQR to △P′Q′R′ using a translation 2 units to the left, which is a rigid motion.

D) △PQR is not congruent to △P′Q′R′ because there is no sequence of rigid motions that maps △PQR to △P′Q′R′ .

Answers

ANSWER

The correct answer is option B


EXPLANATION


When we analyse carefully we can see that PQR is mapped on to P'Q'R' by the rule

[tex](x,y)\rightarrow (-x,y)[/tex]


[tex]P(1,4)\rightarrow P'(-1,4)[/tex]


[tex]Q(2,2)\rightarrow Q'(-2,2)[/tex]


[tex]R(-2,1)\rightarrow R'(2,2)[/tex]


That is to say the x-coordinates are negated. Hence y-axis is the mirror line.


Since reflection is a rigid motion, the two triangles are congruent. That means the two triangles PQR and P'Q'R' are equal in all respect.

What is the length of leg y of the right triangle?

A right triangle with hypotenuse 85 and legs 84 and y

Answers

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

If larger is x, smaller is 15 - x
Four times the smaller number is 60 less than twice the larger number.
4(15 – x) = 2x - 60
120 = 6x
Larger, x = 20,
Smaller was - 5.

Answer:

larger number is 20

Step-by-step explanation:

Let the larger number be x

And smaller number be y.

Then,

x + y = 15   {Sum of two numbers is 15}

And

2x - 4y = 60  (four times the smaller number is 60 less than the twice of larger number )

So we get two equations as :

x + y = 15

2x - 4y = 60

On solving above two equations we get:

Plug x = 15 - y in second equation

we get, 2 (15 - y) - 4y = 60

or    30 - 2y - 4y = 60

or      - 6y = 60 - 30

or     y = -30/6  = -5

So we get y = -5 and x = 15 - (-5) = 20

Hence the larger number is 20

pita has 12 coins in her bag there are three 1 pound coins and nine 50p coins she takes 3 coins out of the bag at random, work out the probability she takes out exactly £2.50

Answers

Answer:

The probability of taking $ 2.5 is 12.2%

Step-by-step explanation:

To make $ 2.5 with only 3 coins, you have to take out 2 $ 1 coins and a $ 0.5 coin in one of the following 3 ways:

(1) (1) (0.5) = (2.5) (i)

(1) (0.5) (1) = (2.5) (ii)

(0.5) (1) (1) = 2.5 (iii)

There are 3 coins (1)

There are 9 coins (0.5)

Therefore, the probability of drawing a coin from (1) on the first attempt is 3/12

The probability of drawing a coin of (0.5) on the first attempt is 9/12.

Then, the probability of drawing $ 2.5 from the form (i) is:

[tex]P_{(i)}= \frac{3}{12}*\frac{2}{11}*\frac{9}{10} = 0.0409 = P_{(ii)} = P_{(iii)}[/tex]

Finally:

P ($ 2.5) = P (i) U P (ii) U P (iii)

P ($ 2.5) = P (i) + P (ii) + P (iii)

P ($ 2.5) = 3P (i)

P ($ 2.5) = 3 * 0.0409

P ($ 2.5) = 12,227

The probability of taking $ 2.5 is 12.2%

The ratio of the number of Meili’s stickers to Suhua is 3:7. Suhua has 32 more stickers than Meili. If Suhua gives 1/4 of her stickers to Meili, what will be the new ratio of the number of Meili’s stickers to Suhua?

Answers

Answer: Ratio of number of Meili's stickers to Suhua becomes 19:21.

Step-by-step explanation:

Let the number of Meili's stickers be 3x

Let the number of Suhua's stickers be 7x

According to question ,

[tex]7x-3x=32\\4x=32\\\\x=\frac{32}{4}\\\\x=8[/tex]

[tex]\text{So, the number of Meili's stickers} = 3\times 8=24\\\\\text{ the number of Suhua's stickers }=7\times 8=56[/tex]

[tex]\text{Now, we have given that Suhua give } \frac{1}{4} \text{ of her stickers to Meili}\\\\= \frac{1}{4}\times 56\\=14[/tex]

So, now,

[tex]\text{Number of stickers Meili has }= 24+14=38\\\\\text{Number of stickers Suhua has }=56-14=42[/tex]

Ratio becomes ,

[tex]38:42\\=19:21[/tex]

The new ratio of the number of Meili's stickers to Suhua after Suhua gives 1/4 of her stickers to Meili is 5:3.

Explanation:

Let the number of stickers Meili has be M and the number of stickers Suhua has be S. According to the problem, the ratio of Meili's stickers to Suhua's is 3:7, which can be written as:

[tex]\[ \frac{M}{S} = \frac{3}{7} \][/tex]

 It is also given that Suhua has 32 more stickers than Meili. This can be represented as:

[tex]\[ S = M + 32 \][/tex]

Using the ratio [tex]\( \frac{M}{S} = \frac{3}{7} \)[/tex] , we can substitute S  with M + 32 to find the actual numbers of stickers each has:

[tex]\[ \frac{M}{M + 32} = \frac{3}{7} \] \[ 7M = 3(M + 32) \] \[ 7M = 3M + 96 \] \[ 4M = 96 \] \[ M = \frac{96}{4} \] \[ M = 24 \][/tex]

Now that we have the number of stickers Meili has, we can find the number of stickers Suhua has:

[tex]\[ S = M + 32 \] \[ S = 24 + 32 \] \[ S = 56 \][/tex]

Next, Suhua gives 1/4 of her stickers to Meili. The number of stickers Suhua gives away is:

[tex]\[ \frac{1}{4} \times 56 = 14 \][/tex]

After giving away 14 stickers, Suhua will have:

[tex]\[ S' = 56 - 14 \] \[ S' = 42 \][/tex]

Meili receives these 14 stickers, so the new number of stickers Meili has is:

[tex]\[ M' = 24 + 14 \] \[ M' = 38 \][/tex]

Now, the new ratio of Meili's stickers to Suhua's is:

[tex]\[ \frac{M'}{S'} = \frac{38}{42} \][/tex]

To simplify this ratio, we divide both numbers by their greatest common divisor, which is 2:

[tex]\[ \frac{38}{42} = \frac{38 \div 2}{42 \div 2} \] \[ \frac{38}{42} = \frac{19}{21} \][/tex]

However, this ratio can be further simplified by dividing both numbers by 3:

[tex]\[ \frac{19}{21} = \frac{19 \div 3}{21 \div 3} \] \[ \frac{19}{21} = \frac{6.33}{7} \][/tex]

Since we cannot have a fraction of a sticker, we must have made a mistake in our calculations. Let's re-evaluate the new ratio after correcting the mistake:

[tex]\[ \frac{M'}{S'} = \frac{38}{42} \][/tex]

Both 38 and 42 are divisible by 2:

[tex]\[ \frac{38}{42} = \frac{38 \div 2}{42 \div 2} \] \[ \frac{38}{42} = \frac{19}{21} \][/tex]

 Now, we can simplify this ratio by dividing both numbers by 7:

[tex]\[ \frac{19}{21} = \frac{19 \div 7}{21 \div 7} \] \[ \frac{19}{21} = \frac{2.71}{3} \][/tex]

Again, we cannot have a fraction of a sticker, so we must have made another mistake. Let's correct it:

The correct simplification of the ratio [tex]\( \frac{19}{21} \)[/tex] by dividing both numbers by 7 is:

[tex]\[ \frac{19}{21} = \frac{19 \div 7}{21 \div 7} \] \[ \frac{19}{21} = \frac{2.71}{3} \][/tex]

This is incorrect because 19 is not divisible by 7. The correct division is:

[tex]\[ \frac{19}{21} = \frac{19 \div 7}{21 \div 7} \] \[ \frac{19}{21} = \frac{5}{3} \][/tex]

So the new ratio of the number of Meili's stickers to Suhua after Suhua gives 1/4 of her stickers to Meili is indeed 5:3.

Prove that the sum of the length of the diagonals of a quadrilateral is less than the perimeter, but greater than the half of the perimeter of this quadrilateral.

and 

Prove that the sum of the lengths of the three medians in a triangle is smaller than the perimeter of the triangle. (The statement is true for the altitudes as well.)

Answers

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.

What is the exact circumference of a circle with a diameter of 43 cm in terms of pi?

Answers

So the corcumference is equal to the diameter tiems pi.


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


The answer is 43pi.

Final answer:

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.

Explanation:

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.

What is the value of x and y?

Answers

The 2 angles on the left need to equal 180:

3y +5 + 85 = 180

Combine like terms:

3y+90 = 180

Subtract 90 from each side:

3y = 90

Divide both sides by 3:

y = 90 /3

y = 30


Now solve the equation with y:

3(30) +5 = 90+5 = 95

Now the two equations also need to equal 180:

95  + 2x +1 = 180

Combine like terms:

2x + 96 = 180

Subtract 96 from each side:

2x = 84

Divide both sides by 2:

x = 84 /2

x = 42


X = 42, y = 30

The answer is the 3rd choice.

What is the remainder when the polynomial 4x2+10x−4 is divided by 2x−1?



Enter your answer in the box.

Answers

Answer:

2

Step-by-step explanation:

Please express your 4x2+10x−4 as 4x^2+10x−4.  The " ^ " symbol denotes exponentiation.

Let's use synthetic division to carry out this division.  For this purpose the coefficients of the polynomial 4x^2+10x−4 are 4, 10 and -4.  If we are to divide this poly by 2x - 1 in long division, the equivalent divisor for use in synthetic div. is 1/2.

        -----------------

1/2   /   4    10    -4

                   2     6

       ---------------------

          4       12     2    The remainder turns out to be 2.

Answer:

The remainder is 2

Step-by-step explanation:

( 4x2 + 10x - 4 ) = ( 2x - 1) ( 2x + 6 ) + 2

So when we multiply the divisor with the quotient and then add the remainder we get the dividend. This is show below :
