Answer 1

Answer:

Answer:

isosceles

Step-by-step explanation:

We first find the |TV| |VS| and |ST| of the triangle using the distant formula,

$d =\sqrt{{(x_1 - x)}^(2)+ {(y_1 - y)}^(2) }$

$|TV|=\sqrt{( {9 - 1)}^(2)+{(2-1)}^(2)}$

$|TV|=\sqrt{{8}^(2)+{1}^(2) }$

$|TV|=√(64+1)$

$|TV|=√(65)units$

$|VS|=\sqrt{({5- 9)}^(2)+{(8 -2)}^(2)}$

$|VS|=\sqrt{({ - 4)}^(2)+{6}^(2)}$

$|VS|=√(16+36)$

$|VS|=√(52)units$

$|ST|=\sqrt{({5-1)}^(2)+{(8-1)}^(2)}$

$|ST|=\sqrt{4^(2)+7^(2)}$

$|ST|=√(16+49)$

$|ST|=√(65)units$

It can be seen that |ST|=|TV|

This implies that the triangle has its two sides equal.

Therefore the triangle TVS is isosceles.

Note that scalene triangle has three nonequal sides whiles equilateral triangle has three equal sides.

A window is 21 inches wide, and its perimeter is 112 inches. What is the length of the window?

Answers

Answer:

The length of the window is 35 inches.

Step-by-step explanation:

Perimeter of an object can be found using the general formula: P = 2W + 2L, where P = perimeter, W = width and L= length. Since both the width and perimeter of the window are given, we can plug these values into the formula to solve for the missing variable 'L': 112 = 2(21) + 2L, or 112 = 42 + 2L. We can then use inverse (opposite) operations to isolate the variable and solve. Whatever we do to one side of the equation, we do to the other. We will start by subtracting 42 from each side: 112 - 42 = 42 - 42 + 2L or 70 = 2L. Next, we divide both sides by 2 to solve for L: 70/2 = 2L/2 or L = 35. So, the final length of the window is 35 inches.

the local amusement park is a popular field trip destination. this year the senior class at high school a and the senior class at high school b both planned trips there. the senior class at high school a rented and filled 9 vans and 5 buses with 267 students. high school b rented and filled 10 vans and 10 buses with 390 students. each van and each bus carried the same number of students. how many students can a van carry? how many students can a bus carry?

Answers

The van can carry 18 students and bus can carry 21 students.

Solution:

Given that,

Senior class at high school "a" rented and filled 9 vans and 5 buses with 267 students.

High school "b" rented and filled 10 vans and 10 buses with 390 students.

Each van and each bus carried the same number of students.

Let the capacity of van be "m", and capacity of bus be "n"

Then, according to given information,

For school a ⇒ 9m + 5n = 267 ⇒ (1)

For school b ⇒ 10m + 10n = 390

⇒ m + n = 39

⇒ m = 39 – n ⇒ (2)

Substitute (2) in (1)

9(39 – n) + 5n = 267

⇒ 351 – 9n + 5n = 267

⇒ 9n – 5n = 351 – 267

⇒ 4n = 84

⇒ n = 21

Then, m + 21 = 39

⇒ m = 39 – 21

⇒ m = 18

Hence, van can carry 18 students and bus can carry 21 students.
