Jacob is cutting a tile in the shape of a parallelogram. Two opposite angles have measures of (6 - 70)° and (2n + 10)°. What are the two different angle measures of the parallelogram-shaped tile? • 20° and 160° • 50° and 130° • 30° and 150° ( 70° and 110°
Answer:
50° and 130°
Step-by-step explanation:
Here are the steps to find the two different angle measures of the parallelogram-shaped tile:
Step 1:
Since opposite angles in a parallelogram are congruent, we can set the expressions for the two opposite angles equal to each other:(6n - 70 = 2n + 10) - 2n
(4n - 70 = 10) + 70
(4n = 80) / 4
n = 20
Thus, n = 20
Step 2:
We can substitute 20 for n in 6n - 70 and 2n + 10 to find their respective angle measures:Substituting 20 for n in 6n - 70:
6(20) - 70
120 - 70
50
Substituting 20 for n in 2n + 10:
2(20) + 10
40 + 10
50
So, the two different angle measures of the parallelogram-shaped tile are 50 degrees and 130 degrees (since the sum of two opposite angles in a parallelogram is 180 degrees).

A ball is thrown upward with an initial velocity of 60 mph. it is thrown from a height of 5 feet. what is the maximum height it reaches?
Answer:
h = 61.25 m
Step-by-step explanation:
It is given that,
The initial velocity of the ball, v = 60 m/s
It is thrown from a height of 5 feet, [tex]h_o=5\ ft[/tex]
We need to find the maximum height it reaches. The height reached by the projectile as a function of time t is given by :
[tex]h=-16t^2+vt+h_0[/tex]
Putting all the values,
[tex]h=-16t^2+60t+5[/tex] .....(1)
For maximum height, put
[tex]\dfrac{dh}{dt}=0\\\\\dfrac{-16t^2+60t+5}{dt}=0\\\\-32t+60=0\\\\t=\dfrac{-60}{-32}\\\\t=1.875\ s[/tex]
Put t = 1.875 in equation (1)
[tex]h=-16(1.875)^2+60(1.875)+5\\\\h=61.25\ m[/tex]
So, the maximum height reached by the ball is 61.25 m.
It is 1,325 feet from Kinsey's house to her school. Kinsey walks to school each morning and gets a ride home each afternoon. How many feet does Kinsey walk to school in 5 days?
Answer: 6,625 feet
Step-by-step explanation:
Since she gets picked up in the afternoon, she's only walking one way. This means all you have to do is multiply 1,325 by 5 to get 6,625.

A polynomial function g(x) with integer coefficients has a leading coefficient of 15 and a constant term of 3. According to the Rational Root Theorem, which of the following are possible roots of g(x)?
a. 1/3
b. -15
c. -5
d. 5
9514 1404 393
Answer:
a. 1/3
Step-by-step explanation:
The rational root theorem tells you possible rational roots will be of the form ...
±(factor of 3)/(factor of 15)
Which will be any of ±{1,3}/{1,3,5,15} = {±1/15, ±1/5, ±1/3, ±3/5, ±1, ±3}.
Of these, 1/3 is one of the available choices.
[tex]f(x)=\sqrt{9+ln(x)[/tex] , find the domain
The domain of the function [tex]f(x) = \sqrt{9 + \ln(x)}[/tex] is [tex][e^{-9}, \infty)[/tex].
To find the domain of the function [tex]f(x) = \sqrt{9 + \ln(x)}[/tex], we need to determine the values of [tex]x[/tex] for which the function is defined.
The square root function [tex]\sqrt{x}[/tex] is defined only for non-negative values of [tex]x[/tex]. Therefore, in order for [tex]f(x)[/tex] to be defined, the expression [tex]9 + \ln(x)[/tex] inside the square root must be non-negative.
Let's solve this inequality:
[tex]9 + \ln(x) \geq 0[/tex]
To do this, we subtract 9 from both sides:
[tex]\ln(x) \geq -9[/tex]
Now, we can rewrite this inequality in exponential form:
[tex]x \geq e^{-9}[/tex]

selling price of a $17,100 truck with a 5% sales tax.
Answer:
17100 + 855tax = a total price of 17955
Step-by-step explanation:
We are required to find the selling price of a vehicle given the cost price and sales tax.
The selling price of the truck is $17,955
Given:
Cost price = $17,100
Sales tax = 5%
Amount of tax = 5% of $17,10
= 5/100 × 17,100
= 0.05 × 17,100
= $855
Selling price = cost price + amount of tax
= $17,100 + $855
= $17,955
Therefore, the selling price of the truck is $17,955

if one gallon of paint covers 825sq.ft how much paint is needed to cover 2640 sq.ft
Answer:
4 (3.2 exactly but you can't go to the store and say I want to buy 3.2 gallons of paint. They will look at you funny, So in this case you will by 4)
Step-by-step explanation:
2640/825 = 3.2 gallons
Answer:
Step-by-step explanation:
1 gallon = 825 square feet
x gallons = 2640 square feet
1/x = 825/2640 Cross multiply
825 x = 2640 Divide by 825
x = 2640/825
x = 3.2 gallons.
The 0.2 has to be rounded up (usually you would round down. That's because you have to get another gallon to paint the small area that is not covered.
So the rounded answer is 4 gallons.

8. AI, Bob, Carol, and Diane shared a $1000 prize. Bob got twice as much as AI,
Carol got 3 times as much as Al, and Diane got $100. How much, in dollars, did
Al get?
Answer:
Al got 150 dollars
Step-by-step explanation:
If we know for certain that Diane receives 100 dollars, than there is 900 left. If Al gets 150, then Bob, getting twice as much, would receive 300, and carol who gets three times as much would get 450. So 450+150+100+300=1000$

Which of the following is an even function?
Of(x) = (x - 1)
f(x) = 8x
f(x) = x2 - x
f(x) = 7
Answer:
f(x) = 7
Step-by-step explanation:
since an even function is defined as a function with the following rule. f(-x) = f(x) for all x in the domain of f(x). It would be odd if f(-x) = -f(x) for all x in the domain of f(x). If f(-x) ≠ -f(x), than it is neither. these are all known as the parity of a function.
you can apply these rules to all of given functions like this. (-x-1) ≠ -(x-1) so it is neither. 8(-x) = -(8x) so it would be odd. 2(-x)-(-x) = -(2x-x) so it is odd as well. This would make f(x) = 7 the only option, as there are no x variables in the equation so 7 = 7.
How to find the inverse for f(x) = 2x-6
Answer:
The inverse is 1/2x +3
Step-by-step explanation:
f(x) = 2x-6
Replace f(x) with y
y= 2x-6
Exchange x and y
x = 2y-6
Solve for y
Add 6 to each side
x+6 = 2y-6+6
x+6 = 2y
Divide each side by 2
(x+6)/2 = 2y/2
1/2 x+3 = y
The inverse is 1/2x +3
Answer:
[tex]{f}^{ - 1} (x) = \frac{x + 6}{2} \\ [/tex]Step-by-step explanation:
[tex]f(x) = 2x-6[/tex]
To find the inverse of f(x) , equate f(x) to y that's
[tex]y = 2x - 6[/tex]
Next interchange the terms that's x becomes y and y becomes x
[tex]x = 2y - 6[/tex]
Next solve for y
Move 6 to the other side of the equation
That's
[tex]2y = x + 6[/tex]
Divide both sides by 2 to make y stand alone
[tex] \frac{2y}{2} = \frac{x + 6}{2} \\ \\ y = \frac{x + 6}{2} [/tex]
We have the final answer as
[tex] {f}^{ - 1} (x) = \frac{x + 6}{2} \\ [/tex]
Hope this helps you
