The price of a notebook has risen to $3.70 today. Yesterday's price was $3.20 . Find the percentage increase. Round your answer to the nearest tenth of a percent.
Answer:
16%
Step-by-step explanation:
Equation: [tex]\frac{new value-old value}{old value}[/tex] * 100
[tex]\frac{3.70-3.20}{3.20}[/tex]* 100= [tex]\frac{0.50}{3.20}[/tex]* 100

Don’t mind the work in the box I didnt have space on the other question.
Answer:
9.3 units
Step-by-step explanation:
By Pythagoras Theorem:
[tex] {x}^{2} + {(18 - 5)}^{2} = {16}^{2} \\ \\ {x}^{2} + {13}^{2} = {16}^{2} \\ \\ {x}^{2} + 169 = 256 \\ \\ {x}^{2} = 256 - 169 \\ \\ {x}^{2} = 87 \\ \\ x = \sqrt{87} \\ \\ x = 9.32737905 \\ \\ x \approx9.3[/tex]

C. Two vectors are said to be parallel if they point in the same direction or if they point in
opposite directions.
i. Are the vectors = < 1> and = <--1> parallel? Show your work and explain.
Type your response here:
ii. Are the vectors = <2, 3> and = <-3, -2> parallel? Show your work and explain.
Type your response here:
Answer:
Hey there,
The answer is below!!
Step-by-step explanation:
Knowing that those vectors start at the point (0,0) we can "think" them as lines.
As you may know, two lines are parallel if the slope is the same, then we can find the "slope" of the vectors and see if it is the same.
A) the vectors are: (√3, 1) and (-√3, -1)
You may remember that the way to find the slope of a line that passes through the points (x1, y1) and (x2, y2) is s = (y2 - y1)/(x2 - x1)
Because we know that our vectors also pass through the point (0,0)
then the slopes are:
(√3, 1) -----> s = (1/√3)
(-√3, -1)----> s = (-1/-√3) = (1/√3)
The slope is the same, so the vectors are parallel.
Part B:
The vectors are: (2, 3) and (-3, -2)
the slopes are:
(2, 3) -----> s = 3/2
(-3, -2)----> s = -2/-3 = 2/3
the slopes are different, so the vectors are not parallel.
answer this please..
Answer:
Answer is 6 because line are parallel

Camila took a taxi from her house to the airport. The taxi company charged a pick-up
fee of $4.80 plus $4.75 per mile. The total fare was $104.55, not including the tip.
How many miles was the taxi ride?
Answer:
104.55 - 4.80 = 99.75
99.75/4.75 = 21
21 miles

What is the value of x?
Enter your answer in the box.
Answer:
x = 111º
Step-by-step explanation:
In a heptagon, (A polygon with 7 sides, and therefore 7 angles), the sum of the interior angles is always 900º (just like the sum of all interior angle in a quadrilateral is always 360º). So you can add up all of the interior angles, and subtract them from 900º.
900º - (158º + 120º + 126º + 125º + 121º + 139º) = 111º

Answer:
3.712 x 10^8
Step-by-step explanation:
use the commutative property to reorder the terms
(5.8x 6.4) x (10^5 x 10^2)
multiply 5.8 x 6.4 = 37.12
add 5+2=8
37.12 x 10^7
write the number in scientific notation
3.712 x 10^8
that'sur answer
Answer: 5.8 x 10^5 =
6.4 x 10^2 =
Step-by-step explanation:
There is 5 10's because number of exponents are 5
so you multiply 5.8 by 10 10 10 10 10
The other is 6.4
multiply that by 10 10
But you can't multiply by all of that with one constant
So you answer the first one 10 x 10 x 10 x 10 x 10 = 100000
the other is 100
So now you multiply 5.8 by 100000
And multiply 6.4 by 100

jessie has $5.40 in nickels and dimes. she knows that the total numbers of coins is 68, and the equation to represent this is n + d = 68, where n is the number of nickels and d is the number of dimes. if jessie needs a system of equations to find the number of each type of coin, what is the second equation of the system?
a. $0.05n + $0.10d = 68
b. n + d = $5.40
c. $0.50n + $0.10d = $5.40
d. $0.05n + $0.10d = $5.40
Answer: d
Step-by-step explanation: $0.05n is 5 cents times how ever many nickels. $0.10 is 10 cents times how ever many dimes. All that equal $5.40, which is the total amount of money.
Answer:
$0.05n + $0.10d = $5.40

One airplane located 200km north and 50km east of an airport. A second plane at the same altitude is located 30km north and 100km west. The distance between the planes is closet to:
Answer: 200
Step-by-step explanation: You can use the Pythagorean theorem for this question. First, you must find a and b. You can do this by finding the distance between North and South, and East and West. For this specific equation, you'd use 200 North - 30 North to get 170 miles on the y-axis. Then, you'd do 50 East + 100 West to get 150 kilometers distance on the x-axis. Now that you have 170 and 150, you can begin the equation
170^2 + 150^2 = c^2
28900 + 22500 = c^2
51400 = c^2
√51400 = √c^2
~226 = c
They are approximately 226 kilometers apart, and 226 is closest to 200, which is B.
