Answer:

(-1.5, 2)

Step-by-step explanation:

Add both x coordinates, divide by 2.

(-5) + 2 = -3

-3/2 = -1.5

Add both y coordinates, divide by 2.

5 + (-1) = 4

4/2 = 2

Answer:  The required co-ordinates of the midpoint S are (-1.5, 2).  

Step-by-step explanation:  Given that S is the midpoint of a line segment QR, where the co-ordinates of he endpoints are Q(-5, 5) and R(2, -1).

We are to find the co-ordinates of the midpoint S.

We know that

the co-ordinates of the midpoint of a line segment with endpoints (a, b) and (c, d) are

[tex]\left(\dfrac{a+c}{2},\dfrac{b+d}{2}\right).[/tex]

Therefore, the co-ordinates of the point S are

[tex]\left(\dfrac{-5+2}{2},\dfrac{5+(-1)}{2}\right)\\\\\\=\left(\dfrac{-3}{2},\dfrac{4}{2}\right)\\\\=(-1.5,2).[/tex]

Thus, the required co-ordinates of the midpoint S are (-1.5, 2).

Answer: 2/3

Step-by-step explanation: In this problem, we have 8/15 ÷ 4/5. Dividing by a fraction is the same as multiplying by its reciprocal. In other words, we can change the division sign to multiplication and flip the second fraction.

8/15 ÷ 4/5 can be rewritten as 8/15 × 5/4

Now, we are simply multiplying fractions so we multiply across the numerators and multiply across the denominators.

8/15 × 5/4 = 40/60 = 2/3

12+34 = 46

Please mark Brainliest if this helps!

Sum: the total of 2 or more numbers added together

12 + 34 = 46

To obtain the product, each element in the expression [tex]\([8, -1, -5, 9]\)[/tex] is multiplied by -4, resulting in [tex]\([-32, 4, 20, -36]\).[/tex]

To find the product of -4 and the expression [tex]\([8, -1, -5, 9]\),[/tex] we multiply each element in the expression by -4.

This involves multiplying -4 by 8, -1, -5, and 9 individually.

The result of these multiplications is [tex]\([-32, 4, 20, -36]\).[/tex]

In other words, each element in the original expression is multiplied by -4 to obtain the corresponding element in the product.

This operation is a scalar multiplication, where a single number (in this case, -4) is multiplied by each element of a vector or array.

Scalar multiplication is a fundamental operation in linear algebra and is used to scale vectors or matrices by a constant factor.

In this context, multiplying the expression by -4 changes the magnitude of each element by a factor of 4 while preserving their relative positions within the array.

Answer:

the answer is 8

Step-by-step explanation:

Add 40+20+15

once you do that you get 75. You then take 650 and divide by 75.

In result you get 8.66666666666 repeated.

So you can only have 8 players.

Answer:

8 players will get all these items.

Step-by-step explanation:

The 8th grade soccer team has a budget of $650.

Soccer cleats cost $40, shin guards cost $20, and the uniform cost $15.

And all these are required by all players.

So, total cost per player = [tex]40+20+15=75[/tex] dollars

And total money the team has = $650

So, the number of players that will be covered from this budget is =

[tex]\frac{650}{75}[/tex] = 8.66 (rounded to 8)

So, a total of 8 players will get all these items.

Note: If we round this to 9, then the budget will exceed to [tex]9\times75=675[/tex] dollars

product of 7 and x i

[tex]9 < 7x[/tex]

The sentence given can be written mathematically as : 12¾ < 7x

Using the parameters given ;

Combining the information given;

12¾ less than the product of 7 and x

The sentence given can be written mathematically thus;

Complete Question :

Write the inequality: 12 3/4 less than the product of 7 and a number x

This is an arithmetic sequence with the first term adding 5 to get to the next term.

To find the slope of a line that passes through the points (0,0) and (2,4), you need to find the rise over run, or the change in y over the change in x. To do this, you need to take both the y values and subtract one from the other, so in this case, subtract 4 from 0. This is your change in y, also known as the rise of your slope. Next you do the same for your x values, in this case you would subtract 2 from 0. This becomes your change in x, also known as the run of your slope.  ( I included step by step equations below)

Slope = [tex]\frac{y2-y1}{x2-x1}[/tex] = [tex]\frac{0-4}{0-2}[/tex] = [tex]\frac{-4}{-2}[/tex]

When you simplify your answer you get a slope of 2.

To solve for the number of each type of soccer ball sold for $2,400 in total and a combined quantity of 70 balls, we set up a system of equations. However, without specific pricing for each type of ball, it's impossible to provide a unique solution. The ideal approach, if prices were known, would be to use substitution or elimination methods.

To determine how many of each type of soccer ball were sold by the sports store when a total of 70 soccer balls were sold for $2,400, we can set up a system of equations. Let's call the number of the first type of soccer ball sold x and the second type y. We also know that one type of ball cost more than the other, so let's assume the first type costs a dollars and the second type costs b dollars, with a > b. We can establish the following equations based on the given information:

To solve this system of equations, we would generally need the price of each type of soccer ball. As we do not have this information, we are unable to solve this problem uniquely. However, the general approach would involve using either the substitution method or the elimination method to find the values of x and y. This will give us the number of each type of soccer ball sold.

Answer:

62.83 m²

Step-by-step explanation:

The area of the path is calculated as

area of outside circle - area of reservoir

= πr₁² - πr₂²

where r₁ is the radius of the outer circle and r₂ the radius of the reservoir

diameter of reservoir = 8 m, hence radius = 4 m

radius of outer circle = radius of reservoir + width of path = 4 + 2 = 6 m, thus

area of path = π × 6² - π × 4² = 36π - 16π = 20π ≈ 62.83 m²

The multiplication table does not have to end at factors of 9. You can multiply 3 and 8 by any factor to form an equivalent ratio.

Step-by-step explanation:

The ratio that is equivalent to 3/8 is 9/24.

The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.

To determine an infinite number of ratios that are equivalent to 3/8, multiply by a ratio equivalent to 1

A ratio equivalent to 1 is a ratio such as 2/2 and 3/3.

This multiplication is equivalent to multiplying by 1.

So the ratio does not change.

One example is to multiply 3/8 by 2/2.

3/8 and 6/16 have the same ratio, 3:8.

Divide each numerator by each denominator.

⇒ 3÷8

⇒ 0.375

⇒ 6÷16

⇒ 0.375

It will also generate the same outcome if you divide each numerator by each denominator.

Hence, the ratio that is equivalent to 3/8 is 9/24.

The price of one Wii game is $50

Step-by-step explanation:

Let the cost of 1 Nintendo DS games be x

Cost of 2 Nintendo DS games = 2x

Cost of 3 Nintendo DS games = 3x

Let the cost of 1 Wii game be y

Cost of 4 Wii game = 4y

Cost of 2 Wii game = 2y

Now we are given that Emily went to a toy store that was selling two Nintendo DS games and four Wii games for a total of $240

So, [tex]2x+4y = 240[/tex]  --- A

Emily bought three DS games and two Wii games and spent $160

So, [tex]3x+2y = 160[/tex] ---- B

Plot lines A and B on graph . Intersection point will provide the solution .

[tex]2x+4y = 240[/tex]   -- Green

[tex]3x+2y = 160[/tex] -- Blue

Intersection Point = (20,50)

So, Cost of 1 Nintendo DS games = $20

Cost of 1 Wii game = $50

Hence the price of one Wii game is $50

The price of one WII game is $50.

2n + 4w = 240 equation 1

3n + 2w = 160 equation 2

Where:

n = price of nintendo games

w = price of wii game

In order to determine the required game, multiply equation 1 by 2 and equation 2 by 3

6n + 12w = 720 equation 3

6n + 4w = 320 equation 4

Subtract equation 4 from 3

8w = 400

w = 50

Answer:12,5%

Step-by-step explanation:

In this case 32 represents  one hundred%, and we want to know what is the percentage of 4.  Then it's enough to apply a Rule of Three.  If 32 represents a 100%, 4 will represents X.

This  is 4 x 100 = 400, and then we'll divide between 32

400/32 = 12,5 %

The percent of 32 is 4​ is given as 12.5%

To find the percentage, you divide the part (4) by the whole (32) and multiply by 100:

(4/32) * 100 = 12.5%

To calculate what percent 4 is of 32, you can use the following formula:

(4/32) × 100 = x

Simplifying this expression, we get:

0.125 × 100 = x

x = 12.5

Therefore, 4 is 12.5% of 32.
