Bill weighs 120 lb and is gaining 10 pounds per month. Phil weighs 204 pounds and is losing 4 pounds per month.
How much will Bill and Phil weigh when they weigh the same amount? Answer (write the number only)
Answer:
180 pounds
Step-by-step explanation:
In six months Bill's weight will be increased by 60 pounds
10 pounds*6 months=60 pounds
120+60=180
In six months Phil will lose 24 pounds decreasing his weight from 204 to 180
4 pounds*6 months=24 pounds
204-24=180
Answer:
180 lbs
Step-by-step explanation:
204-24= 180
120+60=180
multiply each by 6

Answer:
x=29
Step-by-step explanation:
We know for a fact that in a square:
- All of its angles have equal measure (90 degrees)
(e.g. Measure of Angle CAT, measure of Angle CST = 90 degrees)
Now that we know the facts, let's try to find x.
Now since we know that all the angles are equivalent to 90 degrees, we can say that Measurement of Angle SCA is 90 degrees. So:
[tex]90=3x+3[/tex]
Next, we'll simply just isolate the x:
[tex]90=3x+3\\90-3=3x+3-3\\87=3x\\\frac{87=3x}{3} \\29 = x[/tex]

Two forces, with magnitudes of 115 pounds and 160 pounds, are acting on an object at angles of 50° and 130°, respectively, with the positive x-axis. Find the magnitude and direction (with the positive .r-axis) of the resultant force.
Answer:
Step-by-step explanation:
x=(115cos50+160cos130)=-28.9254
y=(115sin50+160sin130)=210.6622
m^2=x^2+y^2
m=212.64
angle=180+arctan(y/x)
angle=97.82

13x = 3(X-20) How to solve this algebra equation?
Answer:
x = -6
Step-by-step explanation:
13x = 3(x - 20) {Use distributive method:a(b+c)=(a*b) + (a*c)
13x = 3*x - 3*20
13x = 3x - 60 {Subtract '3x' from both sides}
13x -3x = -60
10x = -60 {Divide both sides by 10}
x= -60/10
x = -6
5(- 3x - 2) - (x - 3) = -4(4x + 5) + 13
Answer:

Step-by-step explanation:
Let's solve your equation step-by-step.
5(−3x−2)−(x−3)=−4(4x+5)+13
Step 1: Simplify both sides of the equation.
5(−3x−2)−(x−3)=−4(4x+5)+13
5(−3x−2)+−1(x−3)=−4(4x+5)+13(Distribute the Negative Sign)
5(−3x−2)+−1x+(−1)(−3)=−4(4x+5)+13
5(−3x−2)+−x+3=−4(4x+5)+13
(5)(−3x)+(5)(−2)+−x+3=(−4)(4x)+(−4)(5)+13(Distribute)
−15x+−10+−x+3=−16x+−20+13
(−15x+−x)+(−10+3)=(−16x)+(−20+13)(Combine Like Terms)
−16x+−7=−16x+−7
−16x−7=−16x−7
Step 2: Add 16x to both sides.
−16x−7+16x=−16x−7+16x
−7=−7
Step 3: Add 7 to both sides.
−7+7=−7+7

14=s/3 what does s equal
===============================================
Explanation:
To isolate s, we need to undo the division. We'll multiply both sides by 3
14 = s/3
3*14 = 3*(s/3)
42 = s
s = 42
-------
As a check,
14 = s/3
14 = 42/3 .... replace s with 42
14 = 14
We get the same thing on both sides, so this confirms we have the correct value of s.

V = AHV = 1260 cm³H = 18 cmFind base area:
A = 1260/18 = 70 cm²Area of the trapezoid:
A = 1/2(b₁ + b₂)hSubstitute given values and solve for h:
70 = 1/2(12 + 8)h70 = 10hh = 70/10h = 7 cmFind area of base

The angle between the hypotenuse and the side labeled x measures 30 degrees. Find the values of $x$ and $y$ . Write your answers in simplest form.
Answer:
y = 6(sq rt 3)
x = 18
Step-by-step explanation:
y = (0.5)(12)(sq rt 3) = 6(sq rt 3)
x = (0.866)(12)(sq rt 3) = (10.392)(sq rt 3) = sq rt 324

The trigonometric function gives the ratio of different sides of a right-angle triangle. The value of x and y is 18 and 6√3 units respectively.
What are Trigonometric functions?The trigonometric function gives the ratio of different sides of a right-angle triangle.
[tex]\rm Sin \theta=\dfrac{Perpendicular}{Hypotenuse}\\\\\\Cos \theta=\dfrac{Base}{Hypotenuse}\\\\\\Tan \theta=\dfrac{Perpendicular}{Base}\\\\\\Cosec \theta=\dfrac{Hypotenuse}{Perpendicular}\\\\\\Sec \theta=\dfrac{Hypotenuse}{Base}\\\\\\Cot \theta=\dfrac{Base}{Perpendicular}\\\\\\[/tex]
where perpendicular is the side of the triangle which is opposite to the angle, and the hypotenuse is the longest side of the triangle which is opposite to the 90° angle.
Let the side with label x be the base of the triangle and y be the perpendicular.
As the length of the base is x while the angle is 30°, and the length of the hypotenuse is 12√3, therefore, the value of x can be written as,
[tex]Cos \theta=\dfrac{Base}{Hypotenuse}\\\\\\Cos (30^o)=\dfrac{x}{12\sqrt3}\\\\\\Cos (30^o) \times {12\sqrt3}={x}\\\\x = {12\sqrt3} \times \dfrac{{\sqrt3}}{2}\\\\x = 18[/tex]
Now, as we know that the length of the perpendicular side is y, therefore, the value of y can be written as,
[tex]\rm Sin \theta=\dfrac{Perpendicular}{Hypotenuse}\\\\\\Sin (30^o)=\dfrac{y}{12\sqrt3}\\\\\\Sin (30^o) \times {12\sqrt3} ={y}\\\\\\y = \dfrac{1}{2} \times 12\sqrt3\\\\\\y = 6\sqrt3[/tex]
Hence, the value of x and y is 18 and 6√3 units respectively.

Abha is climbing a mountain. While covering 20 yards of horizontal distance, Abha’s elevation increases by 40 yards. Consider Abha’s climb as a linear function.
A drawing shows a girl hiking. The vertical distance is forty yards. The horizontal distance is twenty yards.
What is the slope of her climb?
Answer:
The answer is 2
Step-by-step explanation:
The slope of Abha's climb is given by the equation
Slope m = 2
What is an Equation of a line?
The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be A
Now , let the point be P ( x , y )
And , the equation is given by
The horizontal distance covered by Abha x = 20 yards
The vertical distance covered by Abha y = 40 yards
Now , the slope of the point is given by the equation
Slope m = vertical distance covered by Abha / horizontal distance covered by Abha
Substituting the values in the equation , we get
Slope m of Abha's climb = y/x
Slope m of Abha's climb = 40 / 20
Slope m of Abha's climb = 2
Therefore , the slope of the line is m = 2
Hence , The slope of Abha's climb is given by the equation Slope m = 2
