A parade route is 3/4 mile long.There will be a Refreshment add the standAlso be eight refreshment stand at the end of the route. How far are the refreshment stands in feet

Answers

Answer: 440 ft

Step-by-step explanation:

Given

A parade route is [tex]\frac{3}{4}[/tex] mile long

There are 8 refreshment stand at the end of the route

Suppose there are two refreshment stand, so the route is divided into 3 parts, similarly for three stands, the route is divided into 4 parts

For 8 stands, the route is divided into 9 parts

Distance between two stands is

[tex]\Rightarrow \dfrac{\frac{3}{4}}{9}\\\\\Rightarrow \dfrac{1}{12}\ \text{miles}[/tex]

We know, [tex]1\ \text{mile}\equiv 5280\ ft[/tex]

convert miles to feet

[tex]\Rightarrow \dfrac{1}{12}\times 5280\\\\\Rightarrow 440\ ft[/tex]

Step-by-step explanation:

since a full triangle is 180, angles K and L must be 90 when put TOGETHER so each one would have to be less than 90 :)

Answer:

Acute

Step-by-step explanation:

Since a triangle adds up to 180 subtract 90. this leaves you with 90 and since there are two angles it has to be less than 90 which is an acute angle

Answers

Answer:

y = 5x + 4

Step-by-step explanation:

First I found the slope by using the the definition that slope is rise/run so I saw that the y value went up from 4 to 9 which is 5 units and then the x value went up one in that same time. This means that the slope is 5/1. Then I found the y intercept by seeing where x = 0. On the graph you can see the line touches the y - axis at a value of 4 which means that the y - intercept is 4. Plugging these values into the y = mx + b equation you get y = 5x + 4.

Answer:

y = 5x + 4

Step-by-step explanation:

Slope-intercept form uses the formula y = mx + b where m is the slope and b is the y-intercept.

The slope is 5, because from one point to another, you go up 5 and over one (5/1)

So you can substitute the slope into the formula:

y = (5)x + b

The y intercept is 4 because that is where the line crosses the y axis.

So substitute that:

y = (5)x + (4)

y = 5x + 4

0x has no value they're just putting that in there to trip you up. Also you can view the graph on Desmos graphing calc online to see the minimum value of this function.

x is positive so parabola opens up: meaning minimum value

y-intercept is (0, - 1) so minimum value = -1
