Answer:
101
Step-by-step explanation:
Angles 1 and 2 together equal 180, Angle 1 is 79 therefore
180 = Angle 1 + Angle 2
180 = 79 + Angle 2
180 - 79 = Angle 2
101 = Angle 2
Answer:
Number of birds = 13
Explanation:
An animal shelter spends $1.50 per day to care for each bird and $3.50 per day to care for each cat.
Let the number of bird be 'a' and number of cat be 'b'.
Total money spent = 103.5
1.5 a + 3.5 b = 103.5 ------------------------equation 1
Total number of birds and cats = 37
a + b = 37 ------------------------equation 2
1.5 x equation 2
1.5 a + 1.5 b = 55.5 ------------------equation 3
equation 1 - equation 3
2 b = 103.5 - 55.5 = 48
b = 24
Substituting in equation 2
a = 37 - 24 = 13
Number of birds = 13, Number of cats = 24.
Answer:
The average yearly change in samanthas height was of 3.3 inches.
Step-by-step explanation:
She mesured 40 1/2 = 40.5 inches.
In 5 1/2 years = 5.5 years, she grew to 57 inches.
During the 5 1/2 years, what was the average yearly change in samanthas height?
The total change was of 57-40.5 = 16.5 inches
16.5/5 = 3.3
The average yearly change in samanthas height was of 3.3 inches.
Hello :
<span> f(x) = -5x² +x+1
</span>a = -5 b = 1 c = 1
the vertex is the point A(-b/2a ; f(-b/2a) )
-b/2a = (-1/-10) = 1/10 = 0.1
f(1/10) = -5(1/10)²+(1/10)+1 =21/20 = 1.05
