The number of boys were  1750 boys  and the number of girls were 700 girls  .

In the question ,

it is given that ,

the ratio of the number of girls to the number of boys is 2 : 5.

So , the number of boys is = 5x

and the number of girls is = 2x ,

also given that , the total number of students is = 2450

So , According to the question ,

5x + 2x = 2450

7x = 2450

Dividing both sides by 7 ,

we get ,

x = 2450/7

x = 350 ,

Hence , the number of girls = 2(350) = 700

and the number of boys is = 5(350) = 1750 .

Therefore , there are 700 girls and 1750 boys .

Step-by-step explanation:

you do understand that the diameter of a circle is simply 2 times the radius, yes ?

imagine a circle and you draw a radius line (from the center of the circle to the circle arc).

and now imagine to draw another radius line, just in the opposite direction.

when you look at the result, you have 1 straight line going from the circle arc to the circle arc and passing through the center of the circle. that is what a diameter is.

how long is it ? well, we drew 2 radius lines to create this line. so, it is 2×radius long.

so, the diameter of the seal is

The explicit formula for the given arithmetic sequence is aₙ = 23 + (n - 1)11. Here the first term is a1 = 23 and the common difference is d = 11.

The explicit formula for an arithmetic sequence gives the nth term of the sequence. I.e.,

aₙ = a1 + (n - 1)d

Here a1 is the first term; d is a common difference, it is calculated by

d = aₙ₊₁ - aₙ = aₙ₋₁ - aₙ

The given sequence is 23, 34, 45, 56,...

Here the first term a1 = 23

So, the common difference between the terms in the sequence is

d = 34 - 23 = 11

Then, the explicit formula for the given sequence is

aₙ = a1 + (n - 1)d

⇒ aₙ = 23 + (n - 1)11

Therefore, the nth term of the explicit formula for the given arithmetic sequence is aₙ = 23 + (n - 1)11.

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

given:

Let x be the amt of type 1 and y be the amt of type 2.

Then, Storage constraints

x ≤ 100

y ≤ 150

and, Mixing constraint:

62x + 44y ≤ 7220

44y = 7220-62x

y = 164 - 1.4x

and, Packaging constraint:

78x + 46y ≤ 8260

46y = 8260 - 78x

y = 180 - 1.7 x

Then, The objective functions for each corner of the region

The perimeter of the triangle is 24 units.

What is a triangle?

Triangle is bounded area by three sides. If length of all sides is not equal, then the triangle is known as an obtuse triangle.

The vertices of the triangle are A(-4,4), B(4,4), and C(4,-2)

The formula distance between two points (x₁, y₁) and (x₂, y₂) is √[(x₂ - x₁)² + (y₂ - y₁)²]

The length of line segment AB is √[(4 - (-4))² + (4 - 4)²] = √8² = 8 units

The length of line segment BC is √[(4 - 4)² + (-2 - 4)²] = √6² = 6 units

The length of line segment AC is √[(4 - (-4))² + (-2 - 4)²] = √[8² + 6²] = √100  = 10 units.

The perimeter of a triangle is sum of all sides of the triangle.

The perimeter of the triangle is

Unit rate = Cost/Amount

So, we have the following representation

Unit rate = 1.40/2.5

The cost of 4.25 grams is calculated as

Cost = Unit rate * Amount

So, we have the following representation

Cost = 4.25 * 1.40/2.5

Answer:

Step-by-step explanation:

76% of 50 is 38

Answer: 38 games

Step-by-step explanation: The answer is actually pretty simple to get to. You just need to find 76% of 50. Let x be the amount of games they have won this year. The equation is: x= 0.76*50. Why it is 0.76 instead of 76 is because percent is always out of 100 that is why the max is 100%. So 0.76 is the same as 76/100 which is also 76%. Back to the equation: x = 0.76*50. If you solve the equation which is just 0.76*50, you would get 38. 38 is how many games they won in the season.

When we apply coupon before promotional discount, we have to pay $396.

When we apply promotional discount first and then coupon, we have to pay $392

Given,

The coupon amount = $40

Promotional discount = 10%

The rent per hour = $100 + 20% gratuity

The rent for 4 hours including gratuity = (100 × 4) + (100 × 4 + 10/100) = $480

We have to find the amount for the situations given below;

a) The coupon is applied before the promotional discount;

Here,

Coupon deduction;

480 - 40 = $440

Promotional discount deduction;

10% of 440 = 44

Then,

440 - 44 = $396

We have to pay $396.

b) The promotional discount is applied before coupon;

Here,

Promotional discount deduction;

10% of 480 = 48

Then,

480 - 48 = $432

Coupon deduction;

432 - 40 = $392

The first step to answering this question is to find the slope of the first line. To do that, we need to put it in slope-intercept form.

y=7x+5  => y=7x+5

So the slope of this line is 7. Perpendicular lines have a negative reciprocal slope, so the slope of the perpendicular line is 7. Using that and the point (1,3) we can make an equation for the line in point-slope form:  We can then convert this into slope intercept form.
