The first question is clearly incomplete. The model is not presented so we cannot estimate the volume of the flask but if it was given, the volume is equal to the volume of the cylinder plus the sphere. The cylinder volume is V = pi(r^2)h.
To find the volume of the sphere we use the given equation <span>4/3πr^3. The radius is 4.5/2. The volume is 47.71 cubic inches. </span>
Answer:
Step-by-step explanation:
Answer:
C. (-1, 3)
Step-by-step explanation:
Label the 2 equations:
5y= 7x +22 -----(1)
x= -6y +17 -----(2)
Substitute (2) into (1):
5y= 7(-6y +17) +22
5y= -42y +119 +22 <em>(</em><em>Expand</em><em> </em><em>bracket</em><em>)</em>
5y= -42y +141 <em>(</em><em>Simplify</em><em>)</em>
42y +5y= 141 <em>(</em><em>+</em><em>42y</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>)</em>
47y= 141
y= 141 ÷47 <em>(</em><em>÷</em><em>4</em><em>7</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>)</em>
y= 3
Substitute y= 3 into (2):
x= -6(3) +17
x= -18 +17
x= -1
Thus, the solution is (-1, 3).
Answer:
<h2>The slope is 100</h2>
Step-by-step explanation:
Given that the equation that represents the total cost is given as
C=900+100p--------1
this equation is the same as the equation of a straight line, and we can deduce from it when we compare it the straight line equation
the equation of a line is given as
y=mx+c------2
comparing equation 1 and 2 we have the slope as
m=100
In the context of this problem m=100 means that the cost of producing a phone per material and labour cost is $100
A plane's<span> engines are designed to move it forward at high speed. That makes air flow rapidly over the wings, which throw the air down toward the ground, generating an upward force called lift that overcomes the </span>plane's<span> weight and holds it in the sky. ... The wings force the air downward and that pushes the </span>plane<span> upward.</span>
