Answer:
3
Step-by-step explanation:
Long story short it's 3, how do I know without calculating? because this is the most common example used when people start learning about the Pythagorean theorem. 3^2 + 4^2 = 5^2
But anyways here is how to solve it
The formula for these questions is a^2 + b^2 = c^2, otherwise known as the Pythagorean theorem. a and b represent the sides that are going vertically and horizontally, doesn't matter which is which. c is the line going down diagonally, also known as the hypotenuse.
So here
a^2 + b^2 = c^2, replace b or a doesn't matter with 4 and c with 5 specifically.
a^2 + 4^2 = 5^2, now just solve for a
a^2 + 16 = 25
a^2 = 9
a = 3
Answer:
$6.96
Step-by-step explanation:
(4*8.99) + (3*7)
35.96 + 21 = 56.96
50- 56.96 = -6.96 So she owes 6.96
Answer:
(3) 49
Step-by-step explanation:
The circle diagram is attached below. angle mVS = 146°
and angle mST = 64°.
mWT = 360 -64 - 146 = 150 (angle at a point)
∠ VWS = 73° = mVS / 2
MVW = 180 - 146 = 34 (angle in a straight line)
MVW = 180 -73 - 34 = 73° (angle in a triangle)
∠TMR = 180 - 64 = 116° (angle on a straight line)
∠VMT = 116 + 34 = 150°
∠ MVT = ∠ MTV (base angles of an isosceles triangle)
150 +2∠ mTV = 180
∠ MTV = 15°
∠RVW = 73 - 15 = 58°
∠RVW + ∠ VWS + ∠VRW = 180
∠VRW = 180 - 58 - 73 = 49
Answer:
most I know I don't know and I don't want to know
If I'm correct...
The expression is not an equation. It is not solvable. I believe your expression here would be 1/3n because it is asking the relation of <em>n</em> feet to yards. Converting to yards from feet is to divide by 3, or multiply by the reciprocal, 1/3. So, by plugging your number of feet into the expression in place of <em>n</em>, you essentially divide by 3 and get your number of yards.
The equation is the actual solvable statement. You can use the expression to solve this. In the first part, you used the variable <em>n</em> for the number of feet. In this part, you use <em>f</em> instead. This new expression would be 1/3f. Now, what is that expression equal to? Well, you're solving for the number of yards. So, if the number of yards is represented by <em>y</em>, then the equation should be y=1/3f.
