Answer:
40%
Step-by-step explanation:
To find the percentage difference between the families with 2 dogs and the families with no dogs, we need to find their difference first.
Difference = 45 - 27
= 18
Now that we know the difference, we just have to put the difference over the total as a fraction and multiply by 100%.
Percentage difference = 
× 100%
= 40%
Answer:

You have 2 right triangles. You can use the Pythagorean theorem for each one.
a^2 + b^2 = c^2
Let y = length of vertical side between triangles.
Left triangle:
5^2 + y^2 = 13^2
25 + y^2 = 169
y^2 = 144
y = 12
Right triangle:
3.5^2 + 12^2 = x^2
12.25 + 144 = x^2
x^2 = 156.25
x = 12.5
Answer: x 12.5 cm

For <X, 2.0 ft is adj leg. 2.9 ft is hyp.
cos X = 2.0/2.9 = 0.6897
X = cos^1 0.6897 = 46.397 deg
sin X = sin 46.397 deg = 0.7241
Answer:
slope is 2. y-intercept is (0,5)
Step-by-step explanation:
The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept. y = mx + b. Find the values of m and b using the form y = mx + b.
X=15
Y=3
2(15)=30
3(3)=9
30+9=39
