Answer:
x = 19
Step-by-step explanation:
The two angles form a right angle
A right angle has a measure of 90 degrees
Thus, x + 14 + 3x = 90
^This is the equation we will use to solve for x
x + 14 + 3x = 90
step 1 combine like terms
x + 3x = 4x
we now have 4x + 14 = 90
step 2 subtract 14 from each side
90 - 14 = 76
14 - 14 cancels out
we now have 76 = 4x
step 3 divide each side by 4
4x / 4 = x
76 / 4 = 19
we're left with x = 19
Answer:
174.8 guppies.g/week
Step-by-step explanation:
B(t) = N(t)M(t)
Utilizing the product rule of derivative
Applying the rule to B(t) = N(t)M(t)
from the question
t=4 weeks, N(4) = 820 guppies
d(N(4))/dt = 50 guppies/week
m(4) = 1.2g
d(M(4))/dt = 0.14g/week
Make a proportion, 2/3=120/x. now solve for x, and get betty has 180
