A triangle has a perimeter of 165cm the first side is 65 cm less than twice the second side the third side is 10 cm less than th

katrin2010 [14]

Answer:

The sides of the triangle are:

Second side = 60 cm

First side = 55 cm

Third side = 50 cm

The perimeter equation can be given as:

$4s-75=165$

Step-by-step explanation:

Given:

Perimeter of triangle = 165 cm

First side = 65 cm less than twice the second side

Third side = 10 cm less than the second side

To find length of each side and write the equation that represents the perimeter of triangle.

Solution:

Let length of second side be = $s$ cm

First side will be given as = $(2s-65)$ cm

Third side will be given as = $(s-10)$ cm

Perimeter of triangle = Sum of all sides

Thus, perimeter can be given as:

⇒ $First\ side+ Second\ side+Third\ side$

⇒ $2s-65+s+s-10$

Simplifying by combining like terms.

⇒ $4s-75$

We know the perimeter of triangle = 165 cm

So, the perimeter equation can be given as:

$4s-75=165$

Solving for $s$ .

Adding 75 both sides.

$4s-75+75=165+75$

$4s=240$

Dividing both sides by 4.

$\frac{4s}{4}=\frac{240}{4}$

$s=60$

Thus, the sides of the triangle are:

Second side = 60 cm

First side = $2(60)-65$ = 55 cm

Third side = $60-10$ = 50 cm

What is the perimeter of A ABC?

Advocard [28]

Answer: 11.4

Step-by-step explanation:

Using the distance formula,

$AC=\sqrt{(-3-1)^2 + (-1-2)^2}}=5\\\\AB=\sqrt{(-3-0)^2 +(-1-3)^2}=5\\\\BC=\sqrt{(1-0)^2 + (2-3)^2}=\sqrt{2} \approx 1.4\\\\\implies P \approx 5+5+1.4=\boxed{11.4}$

frez [133]

Answer:

Sally has 1,532 stickers remaining.

Step-by-step explanation:

First, you have to determine the total amount of stickers Sally bought by multiplying the number of sheets she bought for the number of stickers in each sheet:

124*14=1,736

Now, you have to subtract the number of stickers Sally gave away to her family and friends from the total amount of stickers she bought:

1,736-204=1,532

According to this, the answer is that Sally has 1,532 stickers remaining.

A city has designed a survey to collect information about residents’ opinions about city services. Which of the following descri

Bias refers to scenarios which might affect the ability of a statistical experiment to generalize, hence affecting the validity of research. Non-response bias occurs when majority of subjects fail to respond during a survey. Hence, a likely scenario is ; surveys were mailed to 500 people, and 200 of the surveys were completed and returned.

Non - response bias has to do with a situation whereby a large percentage of the selected samples from a population do not respond or fail to participate in the experiment or survey.

If 200 surveys were returned, then 300 of the sample participants did not respond. Which means 60% of the sample are non-responsive.

Therefore, a scenario where surveys were mailed to 500 people, and 200 of the surveys were completed and returned exemplifies a non - response bias.
