Answer:

The answer to your question is 420 ft²

Step-by-step explanation:

Data

side = 6 ft

distance from the center to the vertex = 5 ft

height = 10 ft

Process

1.- Calculate the apothem

c² = a² + b²

a² = c² - b²

a² = 25 - 9

a² = 16

a = 4

2.- calculate the area of the base

Ab = 2(Perimeter x apothem)/2

Ab = (6 x 5) x 4

Ab = 120 ft²

3.- Calculate the lateral area

Al = (6 x 5) x 10

Al = 300 ft²

4.- Total area

At = 120 + 300

= 420 ft²

Miss Penny inherits £1040

Firlakuza [10]

Answer:

Step-by-step explanation:

first we simplify the ratio

5:8

8/5=1.6

1:1.6 so for every 1 dollar she save she spends 1.6

next we do 1040/1.6=650

1040-650=390

390:650

i hope this helps and is the correct answer pls let me know

4(x-6)<-2x+6 what is the solution to the inequality <br> _

Cloud [144]

Simplify both sides if needed. The left-hand side needs simplification.

4(x - 6) $\leq$ -2x + 6
4x - 24 $\leq$ -2x + 6

All is left to do is add and subtract to get the x variable all alone.

4x - 24 $\leq$ -2x + 6
6x - 24 $\leq$ 6 <-- Add 2x to both sides
6x $\leq$ 30 <-- Add 24 to both sides
x $\leq$ 5 <-- Divide both sides by 6

In order to be in the solution set, x has to be less than or equal to 5.

In interval notation: [5, -∞)

cora says she doesn't need to know the y-intercept of a line to write its equation, just its slope and some other point on the l

Nadusha1986 [10]

Answer:

The equation of line with given slope that include given points is 3 y + x - 20 = 0

Step-by-step explanation:

According to Cora , if we know the slope and points on a line then we can write the equation of a line .

Since , The equation of line in slope-intercept form is

y = m x + c

<u>Where m is the slope of line , and if we know the points ( x , y ) which satisfy the line then constant term c can be get and the equation of line can be formed .</u>

So , From the statement said above it is clear that she is correct .

Now , Again

Given as :

Slope of a line is m = - $\frac{1}{3}$

That include points ( 2 , 6 )

Now from the equation of line as y = m x + c

∴ 6 = - $\frac{1}{3}$ ( 2 ) + c

Or, 6 = - $\frac{2}{3}$ + c

So , c = 6 + $\frac{2}{3}$

or, c = $\frac{18 + 2}{3}$

∴ c = $\frac{20}{3}$

So, The equation of line can be written as

y = - $\frac{1}{3}$ x + $\frac{20}{3}$

Or, 3 y = - x + 20

I.e 3 y + x - 20 = 0

Hence The equation of line with given slope that include given points is 3 y + x - 20 = 0 Answer
