The perimeter of a triangle is the sum of its dimensions

The perimeter of triangle PRT is 36 meters

Start by calculating the side length PT using the following equivalent ratios

[tex]\mathbf{QR : QS = PR :PT}[/tex]

So, we have:

[tex]\mathbf{3 : 8 = 6 :PT}[/tex]

Multiply 3 : 8 by 2

[tex]\mathbf{6 : 16 = 6 :PT}[/tex]

By comparing the ratios, we have:

[tex]\mathbf{PT = 16}[/tex]

So, the perimeter of triangle PRT is calculated using:

[tex]\mathbf{Perimeter = PR + RT + PT}[/tex]

Substitute values for PR, RT and PT

[tex]\mathbf{Perimeter = 3 + 3 + 7 + 7 + 16}[/tex]

Add up the figures

[tex]\mathbf{Perimeter = 36}[/tex]

Hence, the perimeter of triangle PRT is 36 meters

Answer:

y= 27-6x

Step-by-step explanation:

For the first equation you add 6x on both sides which will leave us at

-y=-27+6x. You then divide both sides by a -1 to make the y positive so then it'll give us the equation y= 27-6x . For the second equation subtract 18x on both sides which will leave us with the equation 3y= 81-18x . Divide each side by 3 to get the y by itself. Then the equation will be y=27-6x

3x=10+15-1

3x=24

x=24/3=8

easy

Answer:  See below.

Step-by-step explanation:

(3/2)*(3/4) = 9/8

9/8, or 1 1/8 is greater than 3/4

The factor (3/2) is misleading.  It is 1.5 written as a fraction and its appearance as a fraction makes one think it is a small number.  

The rate at which she bats is an illustration of ratio and proportions

She's expected to bat 574 times in 162 games

In 131 games, she bat 464 times

Represent this as a ratio

[tex]\mathbf{Ratio = 131 : 464}[/tex]

Let the number of times she bat in 162 games be represented with x.

So, the ratio is represented as:

[tex]\mathbf{Ratio = 162 : x}[/tex]

Equate both ratios

[tex]\mathbf{162 : x = 131 : 464}[/tex]

Express as fractions

[tex]\mathbf{\frac{x}{162 }= \frac{464}{131 }}[/tex]

Multiply both sides by 162

[tex]\mathbf{x= \frac{464}{131 } \times 162}[/tex]

Multiply

[tex]\mathbf{x= \frac{75168}{131 } }[/tex]

Divide

[tex]\mathbf{x= 574}[/tex]

Hence, she's expected to bat 574 times in 162 games

Answer:

765 students

Step-by-step explanation:

x- total number of students

20% of x=153

20/100=153/x

20x=15300

x=765

Therefore, 765 students

The total number of RSM students participated in AMC 10 that year if 153 of them were invited to take part in AIME is, 765.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

According to the given information, 20% of RSM AMC 10 participants were invited to compete in AIME.

If 20% of students are 153 then 100% of RSM students participate in AMC10 is given as;

x be the total number of students

Therefore,

20% of x=153

20/100=153/x

20x=15300

x=765

The perimeter of parallelogram PQRS will be 8√2 + 2√10 units.

It is a polygon with four sides. The total interior angle is 360 degrees. A parallelogram's opposite sides are parallel and equal.

On a coordinate plane, parallelogram PQRS is shown.

Point P is at (-2, 5), point Q is at (2, 1), point R is at (1, -2), and point S is at (-3, 2).

In the diagram, SR = 4√2 and QR = √10.

We know SR = PQ and RQ = SP

Then the perimeter of the parallelogram is the sum of all sides.

P = PQ + QR + RS + SP

P = 4√2 + √10 + 4√2 + √10

P = 8√2 + 2√10

Then the perimeter of parallelogram PQRS will be 8√2 + 2√10 units.

Step-by-step explanation:

Answer: a2 + b2 = 202

Step-by-step explanation: Since they are consecutive odd integers, then we can just divide 202 by 2, square root it, then round to the nearest two odd integers. In this case, 202 / 2 = 101 ⇒ 1010.5 ≈ 10.04. The two nearest odd integers are 9 and 11. We can verify that this is the pair: 92 + 112 = 81 + 121 = 202.

If they work together, they need 47 minutes to dig the trench.

An equation is a statement that two expressions, which include variables and/or numbers, are equal. In essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.

It is given that, Marty can dig a 10 ft trench in 90 minutes. Chris can dig a 10 ft trench in 110 minutes.

Marty can dig a 10 ft trench in 90 minutes, and in one minute

10 ft = 90

1 ft = 90/10

1ft = 9 minuted

If Chris can dig a 10 ft trench in 110 minutes, and in one minute

10 ft = 100 minute

1 ft = 100/10

1 ft = 10 minute

If they worked together x minute needed to dig 1 ft,

1/x =1/9+1/10

1/x=1/9+1/10

1=19/90 x

90x=19

x=90/19

x=4.7 minute

For 10 feet,

x = 47 minute

Thus, if they work together, they need 47 minutes to dig the trench.
