a right triangle. All right triangles have an area equal to one

half the product of the two smaller side lengths.

Which statement is valid, based on deductive reasoning?

OA)

A polygon has an area of 6 square units if it is a

triangle

OB)

A triangle has a perimeter of 12 units if its sides are consecutive

integers.

If a triangle has side lengths 3, 4, and 5 units, then its area is 6

square units.

If a triangle has side lengths 4, 5, and 6 units, then its

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:

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

Answer:

C

Step-by-step explanation:

From the given options, only option E.7.777 is a repeating decimal because its decimal part '7' repeats indefinitely.

In mathematics, a repeating decimal is a decimal fraction that after some place repeats the same sequence of digits indefinitely. From the options given: A.-0347, B.3.611, C.-1.35, D.2.153, and E.7.777, we are looking for which numbers have decimal parts that repeat.

Option A.-0347 is not a repeating decimal because the decimal part '0347' does not repeat indefinitely. Option B.3.611 and Option D.2.153 also do not have repeating decimal parts.

Option C.-1.35 does not have a repeating decimal part either. However, Option E.7.777 is indeed a repeating decimal, as the decimal part '7' repeats indefinitely.

Answer:

the answer is 22.23

Step-by-step explanation:

you multiply 2.85 times 7.8 and you get 22.23

Juan needs to spend  22.23 to buy 7.8 pounds of seedless red grapes.

A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.

Given, Juan bought 7.8 pounds of seedless red grapes for 2.85 per pound.

Here the cost of the unit pound is already given, Now to obtain the cost 7.8 pounds we have to multiply the cost of the unit pound and no. of pounds which is,

= (7.8×2.85).

= 22.23.

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.

Answer:

∠RPS = 70°

Step-by-step explanation:

∠RPT is a right angle and

∠RPS + ∠SPT = ∠RPT ← substitute values

∠RPS + 20° = 90° ( subtract 20° from both sides )

∠RPS = 70°

Hey there!

The number of equal parts that something is evenly distributed into is the divisor.

Hope this helps!

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:

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
