Answer:

A triangle is scalene if all of its sides have different lengths. A triangle is isosceles if two sides have equal measurements with each other. A triangle is equilateral if all three sides have equal measurements with each other. That is how you will explain it to your classmate

Answer:

First, look at the side lengths a, b, and c, where c is the longest. Then take the sum of a squared and b squared and compare it to c squared. If they are equal, the triangle is a right triangle. If c squared is less than a squared plus b squared, the triangle is acute. If c squared is greater than a squared plus b squared, the triangle is obtuse.

Answer: The second option and the third option are true.

Step-by-step explanation:

The formula of the line in slope-intercept form is:

$y=mx+b$

Where <em>m </em>is the slope and <em>b </em>is the y-intercept.

By definition, the y-intercept in a direct variation is 0.

Therefore, substituting $m=-3$ and $b=0$ into the equation, you obtain:

$y=-3x+0$

Then, the equation is:

$y=-3x$

As this is a line, it is a linear function.

Therefore, the second option and the third option are true.

A store was keeping track of how many bottles of hand sanitizer and soap bars were sold last week. A bottle of hand sanitizer co

agasfer [191]

Answer:

Hand sanitizer=135 bottles

Bar soap=83 bottles

Step-by-step explanation:

Let x represent the hand sanitizer and y the sop.

-Our problem can be expressed as:

$x+y=218\ \ \ \ \ ...i\\\\4.25x+2.15y=752.20\ \ \ \ \ ...ii$

#Make x the subject in i then substitute in ii to solve;

$x=218-y\\\\\therefore 4.25(218-y)+2.15y=752.20\\\\926.5-4.25y+2.15y=752.20\\\\174.3=2.1y\\\\y=83\\\\x=218-83=135$

Hence, 135 bottles of hand sanitizer and 83 bottles of bar soap were sold.

The area of a rectangle is 99 square units. Its width measures 9 units. Find the length of its diagonal. Round to the nearest te

mariarad [96]

Answer:

14.21 units (14.2)

Step-by-step explanation:

Formula for area is W(L) or width multiplied by length.

The formula for finding the length of a rectangle's diagonal is :

d = $\sqrt{w^{2}+l^{2} }$

Now we solve for d.

d = $\sqrt{w^{2} + (\frac{A}{W})^{2}$

= $\sqrt{9^{2} + (\frac{99}{9})^{2}$

≈ 14. 21267

≈ 14.2
