Answer:
x=60
Step-by-step explanation:
The sum of interior angles of a regular Pentagon is 540°
x+2x+2.5x+x+10+2x+20=540
8.5x=540-30
8.5x=510
x=510/8.5=60
Answer:
x = 60°Step-by-step explanation:
Sum of interior angles of a regular polygon is:
180°(n-2)Pentagon has 5 sides, so sum of angles is:
180°(5-2) = 180°*3 = 540°For the given pentagon we have sum of angle measures as below, and solving for x:
x + 2x + 2.5x + (x +10) + (2x + 20) = 540°8.5x + 30° = 540°8.5x = 510°x = 510°/8.5x = 60°12.
First Rate Rental Charges $40 a day plus $0.25 per mile. Star Rental charges $25 a
day plus $0.45 per mile. Write an equation that could be used to determine the number
of miles, m, that would result in the same cost for one day.
a. 40.25m=25.45m
b. 40m+0.25=25m+0.45
C. 40+0.25m=25+0.45m
d. 419+0.45m=25+0.25m
Answer:
b. 40m+0.25=25m+0.45
Step-by-step explanation:
Step one:
given data
First Rate Rental
Charges $40 a day plus $0.25 per mile.
let the number of days be m
and the total charges be y
y= 40+0.25m---------------------1
Star Rental
charges $25 a day plus $0.45 per mile.
y= 25+0.45m-----------------------2
Step two:
equate 1 and 2 above we have
40+0.25m= 25+0.45m
Solve: y = -7(-13)

uhm i dont even know how to ask for help i dont even know what this subject is called but here oh and i have to plot it on a graph which i need helo with too.
Answer:
It is a proportional relationship
Step-by-step explanation:
Here, we want to know if the relationship is proportional or not
Looking at the table, we can see that every value of x multiplied by 4 will
give y
In simpler terms;
y = 4x
Hence, we have established that there is a proportional relationship between the x and y values
The perimeter of a rectangle is forty inches. The length is
two inches more than three times the width. Find the dimensions of
the rectangle.
Let Width (inches) = X
Let Length (inches) = 3x + 2
40 = (x) + (3x + 2) + (x) + (3x +2)
40 = 8x + 4
-4 -4
36 = 8x
/8 /8
4.5 = x (width)
Length = 3x + 2
length = 3(4.5) + 2
length = 13.5 + 2
length = 15.5 inches
CHECK
40 = 15.5 + 4.5 + 15.5 + 4.5
40 = 20 + 20
40 = 40

Step-by-step explanation:
bend your head to the right and compare to a 90 degree square
it's acute
Answer: 75°
Step-by-step explanation:
m∠BGC + m∠AGB + m∠AGE = 180°
m∠BGC + 31 + 74 = 180°
m∠BGC + 105 = 180°
m∠BGC = 75°
A submarine 50.2 m below the surface of the ocean
goes up 15.6 m. Then it goes down 35.7 m. What is the
submarine's new position relative to the surface of the
ocean? Show your work.
Please help it due today please help
Answer:
101.5 m
Step-by-step explanation:
What you have to do is 50.2 + 15.6 which equals 65.8, and then you add another 35.7 and the answer would be 101.5 m

Mr. Demers is making a drink by adding flavor drops to his water. If he puts 3 drops in a 12 ounce glass of water, how many ounces does he use PER DROP?
Answer:
Step-by-step explanation: if he puts 3 drops in a 12 ounce glass of water he should be using 4 ounces per drop 12 ounces divided by 3 drops gives you 4 ounces per drop
=======================================================
Explanation:
"Per drop" means "per 1 drop" or "for each 1 drop".
We start off with the ratio of
3 drops: 12 ounces
Divide both parts of that ratio by 3 so that "3 drops" turns into "1 drop"
Doing so gets us the new ratio of
1 drop: 4 ounces
So he uses 4 ounces per drop.
How would you solve this?
Answer:
For the equation, you should subtract 2x on both sides to get -y = -2x - 4. Flip the y's negative sign to get a proper function which is y = 2x + 4. The y-intercept is at (0, 4) and each unit will move two units up along the x-axis.
how do I find the inverse of the first function ?
[tex]\boxed{\boxed{\pink{\sf \leadsto Hence \ the \ Inverse \ of \ the \ given \ function \ is \ x^2+2x-4 .}}}[/tex]
Step-by-step explanation:A function is given to us , and we need to find its inverse. So the function is ,
[tex]\bf\implies f(x) = \sqrt{x + 5 } - 1 [/tex]
So , firstly replace x with y in the given function and then solve for y to get its inverse . Taking the given function ,
[tex]\bf \implies f(x) = \sqrt{x+5}-1\\\\\bf\implies y = \sqrt{x+5}-1 \\\\\bf\implies x = \sqrt{y+5}-1 \:\:\bigg\lgroup \red{\sf Replacing \ x \ with \ y .} \bigg\rgroup \\\\\bf\implies x + 1 = \sqrt{y+5}\\\\\bf\implies y+5 = (x+1)^2 \\\\\bf\implies y+5 = x^2+1 +2x \\\\\bf\implies y = x^2+1-5+2x \\\\\bf\implies y = x^2-4+2x \\\\\bf\implies \boxed{\red{\bf f^{-1}(x)= x^2+2x - 4 }}[/tex]
Here I have also attached the graph of , x² + 2x - 4 and √(x+5) - 1. Here blue graph is of √(x+5) - 1 & red of x²+2x-4.
Hence the inverse f -¹(x) of the given function is x² + 2x - 4 .Select the three situations that model a sum of zero.

A wheel makes 35 revolutions per min. How many revolutions does it make per second?
The wheel makes revolutions per second.
(Type an integer or a simplified fraction.)
Answer:
7/12 revolutions per second
The wheel makes revolutions per second is 7/12.
What is the unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given that, a wheel makes 35 revolutions per min.
Here,
35/1 minute × 1 minute/60 seconds
= 35/60
= 7/12 revolution per second
Therefore, the wheel makes revolutions per second is 7/12.
