Answer:

4/6

Step-by-step explanation:

a number which means "x" or u can name any variable u want

so the product of a number and four means

X×4

the increased by one or plus one

X×4+1

is at least 7

X(4)+1=7

4x+1=7

4x=7-1

4x=6

x=4/6

i guess so

lemme know if I'm right

Divide the number 480 in a ratio of 3:5

Schach [20]

If it is a ratio of 3:5 you are dividing 480 into 8 parts (3+5).

So divide 480 by 8: 480/8 = 60

Then the ratio is (3x60):(5x60) or 180:300

To check it is correct, add up the two parts to see that they come to 480:

180+300 = 480. All good.

Hope this helps

Answer :-

9(3+√3) feet

Step by step explanation :-

A triangle is given to us. In which one angle is 30° and length of one side is 18ft ( hypontenuse) .So here we can use trignometric Ratios to find values of rest sides. Let's lable the figure as ∆ABC .

Now here the other angle will be = (90°-30°)=60° .

In ∆ABC ,

=> sin 30 ° = AB / AC

=> 1/2 = AB / 18ft

=> AB = 18ft/2

=> AB = 9ft .

Again In ∆ ABC ,

=> cos 30° = BC / AC

=> √3/2 = BC / 18ft

=> BC = 18 * √3/2 ft

=> BC = 9√3 ft .

Hence the perimeter will be equal to the sum of all sides = ( 18 + 9 + 9√3 ) ft = 27 + 9√3 ft = 9(3+√3) ft .

<h3>Hence the perimeter of the triangular pathway shown is 9 ( 3 + √3 ) ft .</h3>
