<h2>
Answer:</h2>
First day - 25 calls
Second day - 16 calls
Third day - 75 calls
<h2>
Step-by-step explanation:</h2>
You need to set variables and create system of equations first.
First evening= x
Second evening= y
Third evening = z
x+y+z=116
z=3x
y=x-9
Now you plug in the values into the equation x+y+z=116
x+(x-9)+(3x)=116
5x-9=116
5x=125
x=25
You plug in the value of x into the other equations.
x= 25
z= 3*(25)=75
y=(25-9)=16
Rearrange so it corresponds with days...
First day - 25 calls
Second day - 16 calls
Third day - 75 calls
Answer:a.4 dollars per pint
b.4th a pint/ 1 cup per dolllar
c. 5 pints
d.32 dollars
Step-by-step explanation:
x=1 f = 10(5.5)(1) = 55
x=2, f = 10(5.5)(2) = 110
110-55 = 55
2-1 =1
55/1 = 55
average rate of change = 55
Answer:
y = 1/3x + 5/3
Step-by-step explanation:
An equation contains a slope and y-intercept, in the form y = mx + b. To find the slope or m, you need to plug the coordinates into the slope formula.
y2 - y1/ x2 - 1
3 - 0/ 4 - (-5)
= 3 / 9
= 1/3
Now that we know the slope, we need to plug the values of x and y to find the y-intercept.
y = 1/3x + b
3 = 1/3(4) + b
3 = 4/3 + b
5/3 = b
The equation is y = 1/3x + 5/3
Answer:
h=13
P=5
b=12
Step-by-step explanation:
- tanA=<em>p</em><em>÷</em><em>b</em><em>=</em><em>5</em><em>÷</em><em>1</em><em>2</em>
- sin<em>A</em><em>=</em><em>p</em><em>÷</em><em>h</em><em>=</em><em>5</em><em>÷</em><em>1</em><em>3</em>
- <em>c</em><em>o</em><em>s</em><em>A</em><em>=</em><em>b</em><em>÷</em><em>h</em><em>=</em><em>1</em><em>2</em><em>÷</em><em>1</em><em>3</em>
