Answer:
x = 13
Step-by-step explanation:
Add 3x and 4x - 1 together to get 7x-1. Since the angle on the bottom right is 90 degrees, we can safely assume that the remaining angles add up to 90 degrees. Add 1 on both sides to get 7x = 91. Divide 7 on both sides to get 13 as your x value.
To plug in the x value, plug 13 in. The one on the bottom left should equal to 39 degrees and the one on the top right should equal to 51 degrees.

f(x) = Vr²9
g(x) = |x-31
f(x) =
g(x) = x + x2
Answers
Answer:
Please check the explanation.
Step-by-step explanation:
Even Functions:
The function is unchanged when it is reflected about the y-axis.
i.e.
f(-x) = f(x)
Odd Functions:
The function is unchanged when it is rotated 180° about the origin.
i.e.
f(-x) = -f(x)
Neither Functions:
f(-x) ≠ -f(x)
Let us check the given functions:
f(x) = Vx²9plug –x in for x
f(-x) = V(-x)²9
f(-x) = Vx²9
f(-x) = f(x)
Therefore, the function f(x) = Vx²9 is even function.
g(x) = |x-3|plug –x in for x
as
[tex]f\left(-x\right)=|x+3|[/tex]
and
[tex]-f\left(x\right)=-\left|x-3\right|[/tex]
so
f(-x) ≠ f(x)
f(-x) ≠ -f(x)
Thus,
g(x) = |x-3| is neither an even nor an odd function.
g(x) = x + x²plug –x in for x
g(-x) = (-x) + (-x)²
g(-x) = -x + x²
g(-x) = -(x-x²)
so
f(-x) ≠ f(x)
f(-x) ≠ -f(x)
Thus, it is neither an even nor an odd function.
Thus,
g(x) = x + x² is neither an even nor an odd function.

The function f(t)=16t2 represents the distance (in feet) a dropped object falls in t seconds. The function g(t)=s0 represents the initial height (in feet) of the object. A necklace is dropped from a height of 25 feet. After how many seconds does the necklace hit the ground.
Answers
Answer: 1.25 seconds.
Step-by-step explanation:
f(t) = (-16ft/s^2)*t^2 + g(t)
(i just wrote the units of the acceleration as ft per second squared, matching the gravitational acceleration in Earth)
this function will represent the height of a function that is dropped from an initial height g(t).
In this case, we have a necklace dropped from a height of 25 ft.
then g(t) = 25ft.
And the height equation will be:
f(t) = (-16ft/s^2)*t^2 + 25ft
The necklace will hit the ground hen f(t) = 0, then we can impose that and find the value of t.
f(t) = 0ft = (-16ft/s^2)*t^2 + 25ft
(16ft/s^2)*t^2 = 25ft
t = √(25ft/ (16ft/s^2)) = 1.25 s
Then the necklace will hit the ground after 1.25 seconds.
The olive trees in an orchard produce 3,000 pounds of olives a year. It takes 20 pounds of olives to make 3 liters of olive oil. How many liters of olive oil can this orchard produce in a year?
Complete the table to find the liters of olive oil from 100 pounds of olives. From 3,000 pounds of olives.
Answers
Answer:
450 liters
Step-by-step explanation:
It is given that the orchard produces 3000 pounds of oil in a year
Again, we're told that 20 pounds of olives makes 3 liters of oil
Then we're asked to find how many liters of oil the orchard can produce in a year.
If 3000 pounds of olives gets produced in a year
If 20 pounds of olives makes 3 liters of oil, then 3000 pounds of olives will make
3000 / 20 * 3 liters of oil
150 * 3 liters of oil
450 liters of oil
Essentially, the 3000 pounds of olive that the orchard produces in a year will produce a total of 450 liters of oil in a year also
What is the value of the coins?
Answers
Answer:
220 cents, $2.20
Step-by-step explanation:
Count the amount of QUARTERS there are.
7 quarters.
The next coin in the photo is a dime.
4 dimes.
The next coin in the photo is a penny.
5 pennies.
Quarters are worth 25 cents, dimes are worth 10 cents, and pennies are worth 1 cent.
25(7) + 4(10) + 5(1) = v (the total value)
25 * 7 = 175 cents
4 * 10 = 40 cents
5 * 1 = 5 cents
175 + 40 + 5 = v
175 + 40 = 215 cents
215 + 5 = 220 cents
The value of all of those coins is 220 cents, or $2.20.

Mr. Gee's class orders paperback books from a book club. The books cost $2.95 each. Shipping charges are set at $4.00, regardless of the number of books purchased.
A.) If you know how many books Mr. Gee's class orders, can you determine how much money they spend? Write the corresponding expression
B.) Use your expression to determine how much Mr. Gee's class spent buying 24 books.
C.) The class has a budget of $175 to spend on books, how many books can the class order with the $175 budget.
Answers
B.) (2.95 x 24) + 4 = $74.80
C.) (2.95 x 57) + 4 = X
2.95 x 57 = 168.15 + 4 = 172.15
so basically they can buy 57 books without going over $175
