Answer:
The number is 17
Step-by-step explanation:
Data:
r (radius) = 3.5 in
h (height) = 8 in
Adopt:
V (volume) = ?
Ink cost per cubic inch = $0.05/in³
Total cost: ?
<span>Calculate the volume of the paint bucket (its formed being cylindrical), we have:
</span>
<span>What was the total cost of the paint?
</span>price($)___measure(in³)
0.05 ---------- 1
y -------------- 307.72
It is made the rule of three: (<span>directly proportional)
</span>
multiply cross
Answer:
<span>
the total cost of the paint is $15</span>
You subtract 16 from each side of the equation.
Then it will say exactly what number 'n' is.
_______________________________________
The equation is n + 16 = 9
On the left side, you subtract 16 from (n + 16) and you have 'n'.
On the right side, you subtract 16 from 9 and you have -7 .
Now the equation says n = -7
Answer:
see below
Step-by-step explanation:
Since the quadrilateral is inscribed in the circle, the opposite angles add to 180.
<V+ <B = 180
74+ <B = 180
Subtract 74 from each side
74-74+ <B = 180-74
<B = 106
We now need to find arc AB
Arc AC is 2* <V = 2*74 =154
We know arc AC = arc AB + arc BC
154 = arc AB + 86
Subtract 86 from each side
154-86 = arc AB + 86 -86
68 = arc AB
Answer:
Fixed rate is $60.
Step-by-step explanation:
Let us consider per student charge be 'x'.
Let us consider fixed rate be 'b'
Given:
I rent a gym for $150 for 30 students.
So we can say that;
Total amount is equal to sum of number of students multiplied by per student charge and fixed rate.
framing in equation form we get;
Also Given:
another time I rent the gym for $270 for 70 students.
So we can say that;
Total amount is equal to sum of number of students multiplied by per student charge and fixed rate.
framing in equation form we get;
Now we will subtract equation 1 from equation 2 we get;
Dividing both side by 40 we get;
Now we will substitute the value of x in equation 1 we get;
So we can say that the equation can be written as;
Hence we can say that fixed rate is $60 and per student charge is $3.
