Two numbers are in the ratio 2:3 and their sum id 45 then find both number​

Answers

Answer 1

Answer:

Step-by-step explanation:

Let the two numbers be 2x and 3x.

According to the question,

2x+3x=45

5x=45

x=45/5

x=9

so th required numbers are 18 and 27 as

2x=2*9=18

3x=3*9=27

Answer 2

It is given that,

→ Two numbers are in the ratio 2:3.

→ Their sum is 45.

We have to,

find the both required numbers.

Now assume numbers as,

→ 2y and 3y

As per the given information,

→ 2y + 3y = 45

First we can find the value of y,

→ 2y + 3y = 45

→ 5y = 45

→ y = 45/5

→ [y = 9]

The given ratio is,

→ 2 : 3

Let's find the value of 2y,

→ 2y --- {y = 9}

→ 2 × (9)

→ 18

Let's find the value of 3y,

→ 3y --- {y = 9}

→ 3 × (9)

→ 27

Hence, the number is 18 and 27.

Answer: The answer to that problem is the last equation (y = 4x - 7).

Reasoning: Since the slope is 4, it goes with “x”. The y-intercept is -7 and it goes to the end of the equation.

Answer:

y=4x-7

Step-by-step explanation:

here,

the equation of straight line in slope intercept form is;

y=mx+c

( m= slope

c= y-intercept )

soo..

the question has asked for slope 4 i.e. m=4

and y- intercept -7 i.e. c= -7

now.

the required equation is

y= 4x-7

A school in Delhi has its own flag, which is rectangular and divided into 4 rows and 6 columns. The word ‘SCHOOL' is inscribed in the first row, ‘FLAG' in the fourth row, and a purple coloured rhombus is in the middle

Answers

The question is incomplete. The complete question is :

A school in Delhi has its own flag, which is rectangular and divided into 4 rows and 6 columns. The word ‘SCHOOL’ is inscribed in the first row, ‘FLAG’ in the fourth row, and a  purple colored rhombus is in the middle, as shown in the given figure.

Based on this picture of the school flag, answer the following questions:  

(a) What fraction of the flag has the purple rhombus?

Solution :

From the figure, the total number of squares in the flag of 4 rows and 6 columns are : 4 x 6 = 24 blocks

The purple colored rhombus is made on the half of the 4 blocks.

i.e. [tex]$\frac{1}{2} \times 4 = 2\ \text{blocks}$[/tex]

Therefore, the fraction of the flag that has the purple rhombus is :

[tex]$=\frac{2}{24}$[/tex]

[tex]$=\frac{1}{12}$[/tex]

A baseball stadium has 15,002 seats. The lower level has 50 fewer than three times as many seats as the upper level. The middle level has 40 more than twice as many seats as the upper level. You solved for x and found that the upper level has 2,502 seats.

Answers

Answer:

upper level chairs = 2,502 chairs

Lower level chairs = 7,456 chairs

Middle level chairs = 5044 chairs

Step-by-step explanation:

A baseball stadium holds 15,002 seats. The lower level has 50 fewer than three times as many seats as the upper level. The middle level has 40 more than twice as many seats as the upper level. The upper level has( ) seats.

Total chairs in the stadium = 15,002

Let

upper level chairs = x

Lower level chairs = 3x - 50

Middle level chairs = 2x + 40

Total = lower level + middle level + upper level

15,002 = (3x - 50) + (2x + 40) + x

15,002 = 3x - 50 + 2x + 40 + x

15,002 = 6x - 10

15,002 + 10 = 6x

15,012 = 6x

x = 15,012 / 6

x = 2,502

upper level chairs = x = 2,502 chairs

Lower level chairs = 3x - 50

3(2,502) - 50

= 7506 - 50

= 7,456 chairs

Middle level chairs = 2x + 40

= 2(2502) + 40

= 5004 + 40

= 5044 chairs

1. A triangular piece of wood has side lengths 14 cm, 19 cm and 30 cm. The angle between the 14 cm and 19 cm sides need to be known to see if it will fit properly into a cabinet. What is the angle, accurate to one decimal place, between the 14 cm and 19 cm sides? ​

Answers

Answer:

130.1°

Step-by-step explanation:

Using the cosine rule:

[tex] = { \cos }^{ - 1} ( \frac{ {14}^{2} + {19}^{2} - {30}^{2} }{2 \times 14 \times 19} )[/tex]

= 130.146°

The measure of angle is 72.8° (accurate to one decimal place ) between the 14 cm and 19 cm sides.

What is the Cosine Rule?

The Law of Cosines (also called the Cosine Rule) is defined as it relates all three sides of a triangle with an angle of a triangle.

c² = a² + b² − 2ab cos(C)

The cosine rule, also known as the law of cosines, relates all 3 sides of a triangle with an angle of a triangle. it relates the lengths of the sides of a triangle to the cosine of one of its angles.

Given data as :

Length of side a = 14 cm

Length of side b = 19 cm

Length of side c = 20 cm

The angle of C is the between the side a and side b

According to the cosine rule,

c² = a² + b² − 2ab cos(C)

Substitute the values of a, b and c in the Cosine Rule,

20² = 14² + 19² - 2(14)(19)cos(C)

400 = 196 + 361 - 532cos(C)

400 = 557 - 532cos(C)

532cos(C) = 557 - 400

532cos(C) = 157

cos(C) = 157/532

cos(C) = 0.2951

(C) = cos⁻¹(0.2951)

(C) = 72.83

(C) = 72.8° (accurate to one decimal place)

Hence, the measure of angle is 72.8° (accurate to one decimal place ) between the 14 cm and 19 cm sides.

What is Probability?

Probability is simply the possibility of getting an event. Or in other words, we are predicting the chance of getting an event.

The value of probability will be always in the range from 0 to 1.

Given the order of the first 100 customers in a coffee shop.

Number of customers who ordered a large which is also a cold drink = 5

Total number of customers = 100

Probability = Number of desired outcomes / Total number of outcomes

Substituting,

Probability = 5 / 100 = 0.05 = 5%

Hence the required percent is 5%.

So, 1 g of flour requires = 170/250 g of butter = 0.68 g of butter.

Victoria's daughter used: 340 g butter for 400 g flour
