Step-by-step explanation:

Matteo has &400 in his saving account. On average he spends $10 per week on buying apps. Luca has $200 in his savings account. He is saving $15 a week in order to buy a new Playstation. When will matteo and luca have the same amount of money?

Answers

Answer: By the 8th week.

Step-by-step explanation:

Let the time that matteo and luca have the same amount of money be represented by x.

The information given in the question can be formed into an equation as:

400 - 10x = 200 + 15x

Collect like terms

400 - 200 = 15x + 10x

200 = 25x

x = 200/25

x = 8

Matteo and Luca will have the same amount of money by the 8th week.

Find the explicit formula for a 1 =-4,a n =a n-1 +9,n>=2

Answers

Given:

[tex]a_1=-4[/tex] and [tex]a_n=a_{n-1}+9[/tex] where [tex]n\geq 2[/tex].

To find:

The explicit formula for the given recursive formula.

Solution:

We know that recursive formula of an AP is:

[tex]a_n=a_{n-1}+d[/tex]

Where, d is the common difference.

We have,

[tex]a_n=a_{n-1}+9[/tex]

Here, d=9.

The first term of the AP is [tex]a_1=-4[/tex].

The explicit formula for an AP is:

[tex]a_n=a_1+(n-1)d[/tex]

Substituting [tex]a_1=-4[/tex] and [tex]d=9[/tex], we get

[tex]a_n=-4+(n-1)9[/tex]

[tex]a_n=-4+9n-9[/tex]

[tex]a_n=-13+9n[/tex]

Therefore, the required explicit formula for the given sequence is [tex]a_n=-13+9n[/tex].

Answers

Answer:

Step-by-step explanation:

since it tells you y is=1 plug that into the top equation

-1=5x+4

-1=x

and you already have y=-1

so its(-1,-1)

this is simple

since y = -1

y = 5x + 4

-1 = 5x + 4

5x = -5

x = -1

therefore answer is (-1, -1)

Answers

Answer:

£290.70

Step-by-step explanation:

Number of notes of $50 = 5

Total value = 50 × 5 = $250

Number of notes of $20 = 2

Total value = 20 × 2 = $40

Number of notes of $10 = 7

Total value = 10 × 7 = $70

Number of notes of $5 = 3

Total value = 5 × 3 = $15

Total value of all notes with John = 250 + 40 + 70 + 15

= $375

Since, $1.29 = £1

Therefore, $1 = £[tex]\frac{1}{1.29}[/tex]

Therefore, $375 = £ [tex]\frac{375}{1.29}[/tex]

= £290.70

A football team played 90 matches. They won 37 matches.
They drew 1/9 of their matches.
What fraction of their matches did they lose?

Answers

Answer: 44 matches

Step-by-step explanation:

Let's take the given information

They won 37 matches

1/9th of their matches resulted in a draw

1/9 out of 90 is 9

You can take 90/9 and you will get 9

Now let us add 37+9 and you get 47

Now take 90-47

44 Matches lost

Circle a is defined as (x+5)^2 + (y+6)^2 + 16, and circle b is defined as (x+3)^2+(y+2)^2 =9. Which transformation of circle a shows that circle b is similar?

Answers

Answer:

We should use the following transformation: [tex](x', y') = (x+2, y + 4)[/tex] (Translation of circle A to the center of the circle B)

Step-by-step explanation:

We should apply a translation prior to determine if both circles are similar. If we translate the circle A to the center of the circle B. The translation needed is the vectorial distance between both centers:

[tex]T(x,y) = B(x,y)-A(x,y)[/tex] (1)

Where:

[tex]T(x,y)[/tex] - Translation vector.

[tex]A(x,y)[/tex] - Location of the center of the circle A.

[tex]B(x,y)[/tex] - Location of the center of the circle B.

If we know that [tex]A(x,y) = (-5,-6)[/tex] and [tex]B(x,y) = (-3,-2)[/tex], then the translation vector is:

[tex]T(x,y) = (-3,-2)-(-5,-6)[/tex]

[tex]T(x,y) = (2,4)[/tex]

We should use the following transformation: [tex](x', y') = (x+2, y + 4)[/tex] (Translation of circle A to the center of the circle B)

II) 78

Step-by-step explanation:

2x - 6 + 7x + 15 = 90

9x + 9 = 90

9x = 81

x = 9

<ABC:

7x + 15

7(9) + 15

Answer and Step-by-step explanation:

To find the measure of angle ABC, we need to find what x is first. We accomplish this by adding together the two angles and setting it equal to 90.

2x - 6 + 7x + 15 = 90

Combine like terms.

9x + 9 = 90

Subtract 9 from both sides.

9x = 81

Divide both sides by 9.

x = 9

We get x to be 9.

Now, we can plug this in for angle ABC.

7(9) + 15

Multiply 7 and 9 together.

63 + 15

Add 63 and 15 together.

The measure of ABC is 78.

That means the answer is II) 78.

A rectangle's length is three times its breadth x metres. Write an expression
for the rectangle's:
a) perimeter
b) area

Answers

Answer:

1. Perimeter = 8x m

2. Area = 3x² m²

Step-by-step explanation:

From the question given above, the following data were obtained:

Breadth (B) = x m

Length (L) = 3B = 3x m

Perimeter (P) =?

Area(A) =?

1. Determination of the perimeter of the rectangle.

Breadth (B) = x m

Length (L) = 3x m

Perimeter (P) =?

P = 2(L + B)

P = 2(3x + x)

P = 2(4x)

P = 8x m

Thus, the perimeter of the rectangle is 8x m

2. Determination of the area of the rectangle.

Breadth (B) = x m

Length (L) = 3x m

Area(A) =?

A = L × B

A = 3x × x

A = 3x² m²

Thus, the area of the rectangle is 3x² m²

Answer:

x=108 degrees

Step-by-step explanation:

Since ST is a straight line, it measures 180 degrees. This means that x+(2/3)x=180. The simplified version is 5x/3=180. Now, we multiply both sides by 3. The equation becomes 5x=540; which is ultimately x=108.

Answer: x=108 degrees

Step-by-step explanation:

Since ST is a straight line, it measures 180 degrees.

This means that:

x+(2/3)x=180

The simplified version is 5x/3=180. Now, we multiply both sides by 3. The equation becomes 5x=540; which is ultimately x=108.

Is the triangle right-angled? Justify your answer Amelia Earhart was born in 1897 in a small Kansas town. That was six years before the Wright brothers took their famous first airplane flight in Kitty Hawk, North Carolina. Over the next two decades, aviation developed rapidly, but the pilots at the controls were mainly men. Amelia Earhart broke through that barrier to become a famous aviator, and she paved the way for women who followed. Amelia Takes OffAmelia took her first flying lesson in 1921. At the end of the year, she received her pilots license. She took odd jobs and received financial help from her mother to buy her own airplane. With a plane of her own, Amelia quickly began making a name for herself in the aviation world. In October 1922, she broke a world record for female pilots by flying her plane to 14,000 feet in altitude. In 1923, she received her International Pilots Licensejust the sixteenth woman in the world to do so. Unfortunately, Amelia had to sell her plane to give her mother money, and for a while, her love of aviation became more of a hobby.But this all changed in 1928 when Amelia was contacted by publisher George Putnam, who she later married. He invited her to be a passenger on a cross-Atlantic flight. Amelia would have preferred to be the pilot, not the passenger, but at the time, flying a plane over an ocean was considered too dangerous for women.The flight was successful, and Amelia became world-famous as the first woman to fly across the Atlantic. However, Amelia was not satisfied. She did not get to operate the controls during the flight and thought of herself as being no more important to the flights success than a sack of potatoes. She was determined to fly on her own.Amelia Reaches StardomIn 1929, Amelia became involved with an organization called the Ninety-Nines, a group that promoted female pilots in the aviation industry. She was the groups first president. In May of 1932, Amelia crossed the Atlantic again, but this time she was at the controls. She made the trip from Canada to Ireland in 15 hours. She received many medals and awards for her achievement.Amelia hoped her success would open doors for women in aviation and in other fields, so she continued flying and setting records. She became the first person to fly across both the Atlantic and Pacific oceans when she flew from Hawaii to California.An Extraordinary MissionEven after proving she was a world-class aviator, Amelia still wanted more. In 1937, she set off on an amazing trip: flying around the world. Amelia started in California but faced trouble along the way. She became ill, her plane needed repairs, and bad weather forced a change in the flight route. She made it to one of her planned stops near Australia, but she never made it to her next destination. People all over the world were following the news of Amelias tripand now she was missing! President Franklin D. Roosevelt conducted a $4 million rescue mission, but Amelia was never found.Amelia hoped that her actions would inspire other women to follow their dreams. One of her lifelong missions was for the world to recognize that women could have the same careers as men. Even though she died at a young age, just 40 years old, Amelia was an inspiration to many.Amelia Earhart is sitting in her plane with her aviation hat and goggles on.Which elements from Amelia Earhart: Pioneer show that it is not a tall tale?
