Answer: She is 42 Years Old.
Step-by-step explanation: If She is 3 times her age, you have to multiply. and That means you have to do 14 x 3. and that equals 42. Good Luck on Your Test!
<h2><u><em>14 x 3 = 42</em></u></h2>
Answer:
0.25D^2 π in^2.
Step-by-step explanation:
The cross section is a circle of diameter D inches, so its radius is 0.5D inches.
The area of cross section is πr^2
= (0.5D)^2 π
= 0.25D^2 π in^2.
Answer:what grade u in
Step-by-step explanation:
Answer:
x = 8, y = 4
Step-by-step explanation:
To find x use the sine ratio in the right triangle and the exact value
sin60° = 
, thus
sin60° = 
= 
= ( cross- multiply )
x × 
= 8 ( divide both sides by )
x = 8
--------------------------------------------------------------
To find y use the tangent ratio in the right triangle and the exact value
tan60° = , thus
tan60° = 
= 
= ( multiply both sides by y )
4 = y × ( divide both sides by )
y = 4
Slope is calculated as the change in y over the change in x, or rise over run.
The change in y is the difference between the two given y-coordinates: 4 - (-3) = 7
The change in x is the difference between the two given x-coordinates (note that the order of the difference must be the same as the order of the difference of the y values): 1 - 1 = 0
So, 7/0 is the slope, but you cannot divide by 0, so the slope is undefined.
