Answer:
15y+7=12-20y (add 20y to both sides)
35y+7=12 (minus 7 from both sides)
35y = 5 (divide both sides by 35) (5/35=1/7)
y= 1/7
Answer:
64/7 = 64/7 yes y = 1/7
Step-by-step explanation:
To prove this we simply have to plug in!
15(1/7) + 7 = 12 - 20(1/7) (simplify)
15/7 + 7 = 12 - 20/7 (simplify further)
64/7 = 64/7
So yes y = 1/7
The period of a pendulum is the time the pendulum takes to swing back and forth. The function L=0.81t^2 relates the length L in feet of a pendulum to the time t in seconds that it takes to swing back and forth. A convention center has a pendulum that is 110 feet long. Find the period.
Answer:
11.73seconds
Step-by-step explanation:
Given the expression of length L in feet of a pendulum to the time t in seconds that it takes to swing back and forth modeled as;
L = 0.81t²
Given
Length of the pendulum = 110feet
Required
Time (period)
Substitute the given value into the formula
L = 0.81t²
110 = 0.8t²
t² = 110/0.8
t² =137.5
t = √137.5
t = 11.73seconds
Hence the period is 11.73seconds

May someone tell me what the value of x is ?
Answer:
maybe 11? because it says to Subtract the sum of the two angles from 180 degrees. The sum of all the angles of a triangle always equals 180 degrees. Write down the difference you found when subtracting the sum of the two angles from 180 degrees. This is the value of X.

The equation that represents Runner #2 is t = 8.5d where t is time (in minutes) and d is distance in miles). If
Runner #2 runs 2 miles, how many minutes will it take?
Answer:
17minutesStep-by-step explanation:
Given the equation of the time t = 8.5d took by aa runner to ru n. If the runner ran 2 miles, to calculate the time take by the runner to run two miles, we will substitute d = 2 into equation and calculate t as shown;
t = 8.5d
t = 8.5(2)
t = 17.0 minutes
Hence it will take the runner 17minutes to run 2 miles.
Runner #2's equation is an illustration of proportional equations
It will take runner #2 17 minutes to run 2 miles
Runner #2's equation is given as:
[tex]\mathbf{t = 8.5d}[/tex]
When runner #2 runs two miles, it means that:
d = 2
Substitute 2 for d in the given expression.
So, we have:
[tex]\mathbf{t = 8.5 \times 2}[/tex]
Multiply
[tex]\mathbf{t = 17}[/tex]
Hence, it will take runner #2 17 minutes to run 2 miles

Mary has been saving her weekly allowance for the past 20 weeks. She started with $100 and now has $300. Which equation can be used to find the amount of money Mary receives for her weekly allowance?
Answer:
Step-by-step explanation:
You should set this up as an y = mx + b equation. Since 300 is her final number, that will be your y value. She started with 100, so that will be your b value. 20 is the number related to the variable you don't know so that will be your m.
300 = 20x + 100
-100 -100
200 = 20x
divide both sides by 20
10 = x

All direct proportion equations are in the form y = kx, for some fixed number k.
If we had y = 17x, without the 2 at the end, then it would be in the form y = kx with k = 17. In other words, y = 17x is a direct proportion equation.
The 2 at the end is why we don't have a direct proportion equation. The y intercept must be 0. All direct proportion equations go through the origin.

Find the length of the missing side. Leave your answer in simplest
radical form. *
Answer:
About 14
Step-by-step explanation:
For this you use the pythagorean theorem, which says a(a) + b(b) = c(c)
The sides that make the right angle are legs which is A and B
The other side is the hypotenuse which is C
So you set it up as
11(11) + b(b) = 18(18)
121 + b(b) = 324
324 - 121 = 203
so b(b) = 203
but 203 is b squared so you need to find the square root of 203 which is about 14.2478.
If you round that it is 14
Check
11(11) + 14(14) = 18(18)
121 + 196 = 324
317 = 324
