If a 40 foot tree casts a 12 foot shadow find the length of the shadow cast by a 24 foot tree

1 answer:

3 0

40 foot tree = 12 foot shadow
24 foot tree = x foot shadow

(Cross Multiply)

40 × x = 12 × 24
x = 288 / 40
x = 7.2 foot

24 foot tree casts 7.2 foot shadow

The time it takes for an object stopped from a certain speed can be modeled by the equation

yanalaym [24]

Given:
t = 1/2 √v
v = speed of object meters per second

t = 3 seconds

3 = 1/2 √v
3 * 2 = √v
6 = √v
6² = √v²
36 meters = v

v = 36 meters per second

What is the total if your tip is 20% and your subtotal is 7.47

SVETLANKA909090 [29]

Answer:

$8.96

Step-by-step explanation:

To find the total amount, multiply the percentage of the tip (20%) as 0.20 with 7.47

(7.47×0.20=1.494)

Add $1.49 to $7.47

(1.49+7.47=8.96)

And there is your total amount with a 20% tip!

A parallelogram has one angle that measures 118°. What are the measures of the other three angles in the parallelogram?

MariettaO [177]

Step-by-step explanation:

Given

We know that in a parallelogram opposite angles are equal. So 

1st and 3rd angles = 118°

Let 2nd and 4th angles = x

Now

118° + 118° + x + x = 360° ( Being sum of angles of parallelogram) 

236° + 2x = 360°

2x = 360° - 236°

2x = 124°

Therefore x = 62°

Now the measure of other all angles 

118° , 62° , 118°, 62°
