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.
Step-by-step explanation:
A line contains the points (10,7) and (5,-8). Write the equation of the line.
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
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

A construction company is setting up signs on a 6 3/4 mile stretch of road. If the company places a sign every 3/4 of a mile, how many signs will it need?
Note: the company will place a Sign at the beginning of the stretch,
then every 3/4 of a mile.
Answer:
10
Step-by-step explanation:
6 3/4 ÷ 3/4 = 9, and plus the sign at the start of the road it would be 10

f(2) =
Evaluate the function for the given value
You would solve the function but you would replace the variable with the number in the parenthesis. Like if it was f(2)=3x+4 then you would do 3(2)+4 which is 10.

Answer:
1
Step-by-step explanation:
6 - 4x = 6x - 8x+ 4
6 - 4x = -2x + 4
-4x + 2x = 4 - 6
-2x = -2
x = -2/-2
x = 1

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

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
is y = 17 X +2 proportional
Answer: No it is not proportional
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.
