The distance from tree 1 to tree 3 is about 205 meters.

An equation is an expression used to show the relationship between two or more variables and numbers.

Let a represent the distance from tree 1 to 2, b from 2 to 3 and c from tree 3 to 1.

Hence:

a + b = 335

Also:

b + c + a = 540

a + b + c = 540

335 + c = 540

c = 205 meters

The distance from tree 1 to tree 3 is about 205 meters.

Answer:225

Step-by-step explanation:

we start by finding the area of the unshaded triangles and subtracting them from the total area of the box.

The total length of the top is 20 and the total length of the bottom side is 18

20-18=2 so the small unshaded part on the bottom side is 2. with this we can find the left triangle. triangle area is base times height over 2 so the area of the unshaded triangle on the left is 15*2/2=15.

We know the small unshaded bit on the right side is 6 as it is shown on the diagram. again, we can use base times height over 2 to get the area of the top unshaded triangle. 6*20/2= 60.

We can do base times height to find the total area of the rectangle

15*20=300

300-15-60=225

Answer:

a = 12

b = 6

Step-by-step explanation:

You have a 30°-60°-90° triangle which is a special right triangle. We memorize the ratios of the sides and can find the sides given just one side, by using the relationships between the sides, so we don't have to use trig ratios.

Generally, the LONGEST side (hypotenuse) is twice the shortest side. Or, the SHORTEST side is half the longest side (hypotenuse). The LONGER LEG is the short leg × sqrt(3).

Or the SHORT LEG is the

longer leg/sqroot(3)

You are given the long leg here. You have:

Long leg = 6sqroot(3)

So the short leg must be 6.

bc, longer leg IS Short leg×sqroot(3)

short leg =6

Then the LONGEST side (hypotenuse) has to be twice that.

LONGEST side = 12

Where it says "Prove side c" maybe that is like doing a check.

6^2 + (6sqrt3)^2 = 12^2

36 + 108 = 144

144=144

Answer:

2000 is the answer hope it helps

Step-by-step explanation:

selling price=2500

profit=25%

cost price+profit=selling price

let cost price be 100

profit percentage= 25%=25

selling price=100+25=125

selling price= 2500 given,

cost price=(2500/125)×100=2000

cost price of good is 2000.

Given the following coordinate point M (-3, 3), S (6, 3), V (3, -3)​ which was dilated to get the coordinate point M' (-2, 2), S' (4, 2), V' (2, -2)

You can see that the scale factor is the ratio of the x coordinate of the image to that of the preimage as shown:

Missing numerator = 6

Step-by-step explanation:

Let us assume that,

→ Missing numerator = x

Now we have to,

→ Find the required value of x.

Forming the equation,

→ 2/5 = x/15

Then the value of x will be,

→ 2/5 = x/15

→ 2 × 15 = x × 5

→ 30 = 5x

→ 5x = 30

→ x = 30/5

→ [ x = 6 ]

Hence, the value of x is 6.

Answer:

Step-by-step explanation:

x + y = 14 --> x = 14 - y

$0.10x + $0.25y = $2.00, or 10x + 25y = 200

- we can plug this value for x from the first equation into the second:

10(14 - y) + 25y = 200

140 - 10y + 25y = 200

140 + 15y = 200

15y = 60

y = 4 --> 4 quarters ($0.25 x 4 = $1.00)

if y = 4, then x = 14 - y --> x = 10 --> 10 dimes (0.10 x 10 = $1.00)

matches the second equation where these add up to $2.00

Answer:

1 way is 10 dimes and 4 quartes
