By similar triangles we can say...

h/14=5/3.5  multiply both sides by 14

h=70/3.5

h=20 ft

Answer:

The height of the birdhouse is 20ft

Step-by-step explanation:

Length of bird house shadow = 14 feet

Length of your friend shadow = 3.5 feet

Height of your friend = 5 feet

Height of the birdhouse = ?

To find the height of the birdhouse we will compare the quality of the two parameters.

Height of your friend / Length of your friend shadow = Height of the birdhouse / Height of the birdhouse

Therefore we have:

5ft/3.5ft = x/14ft

Cross multiple

3.5x = 70

x = 70/3.5

x = 20ft.

Therefore, the height of the birdhouse is 20ft

I REALLY NEED HELP!!! If someone can answer this quickly and correctly I will give them Brainliest. 1. What is the function rule
Rainbow [258]

Answer:

y= -4x + 3

Step-by-step explanation:

Because the slope is -4/1 which is the same as 4 and 3 is the y-intercept.

Here's the work;

We can just use the first two coordinates which are (0,3) and (1,-1) to get from the x-value 0 to 1 we add 1. and to get from the y-value 3 to -1 we subtract 4. Therefore the slope is -4 and the y- intercept (when x is zero) is 3. Pop that into slope intercept form to get y=-4x +3

Hope that helps and have a great day!
