In a survey of 1,900 people who owned a certain type of car, 570 said they would buy that type of car again. What percent of the people surveyed were satisfied with the car? nothing% of the people surveyed were satisfied with the car. (Type a whole number.)
Answer:
The percentage of people who are satisfied with this car model is 30%.
Step-by-step explanation:
Given that the survey interviewed 1,900 people who own a certain type of car, and of them 570 said that they would buy the same car model again, to determine the percentage of people who are satisfied with that model it is necessary to perform the following calculation :
1,900 = 100
570 = X
((570 x 100) / 1,900) = X
57,000 / 1,900 = X
30 = X
Therefore, the percentage of people who are satisfied with this car model is 30%.

What is the perimeter of JKLM?
Answer:
45
Step-by-step explanation:
∡L ≅ ∡M, given
ΔKLM is isosceles because base angles are congruent
KM ≅ KL and KM = KL
KL = 12
∡K =∡J = 60°, given
∡M = 180 -60 -60 , because sum of angles in a Δ is equal to 180°
∡M = 60
∡K =∡J =∡M = 60°
ΔKJM is is equilateral because all angles have the same measure.
KM = 12
KM = KJ = JM = 12 because the triangle is equilateral so all sides are equal
ML = 9, given
The perimeter of JKLM is the sum of the sides
P = ML +KL +KJ +MJ
P = 9 + 12 + 12 +12 = 9 +36 = 45

Find an ordered pair to represent in the equation vec t =4 vec t +6 vec v vec u =(-1,4) and and
Answer:
(14, 4)
Step-by-step explanation:
The question is not well structured and incomplete.
Restructured
Find an ordered pair to represent in the equation vec t = 4 vec u +6 vec v where vec u =(-1,4) and vec v = (3,-2)
Substitute the given vector into the expression for vec t.
Recall that: vec t = 4 vec u +6 vec v
vec t = 4(-1,4)+6(3,-2)
vec t = (4(-1), 4(4)) + (6(3), 6(-2))
vec t = (-4, 16) + (18, -12)
vec t = (-4+18, 16+(-12))
vec t = (14, 16-12)
vec t = (14, 4)
Hence an ordered pair to represent vec t in the equation is (14, 4)
Note that the vec v was assumed. Any other vector coordinate can also be used
express the first quantity as a percentage of the second
a. 80cents of $9.60
Answer this question. please. I really need help
Answer:
8.33%
Step-by-step explanation:
We are told to:
Express the first quantity as a percentage of the second
a. 80cents of $9.60
The first quantity is 80 cents, the second quantity is $9.60
Step 1
We convert 80 cents to a dollar
100 cents = $1
80 cents = $x
$x = 80/100 = $0.8
Step 2
We express $0.8 as a percentage of $9.60
Hence, we have:
$0.8/$9.60 × 100
= 8.33%
A cyclist travels 5 miles in the direction N 30° E, then travels 3 miles in the direction N 70° E. Which equation
measures the cyclist's distance, x, from the starting point?
52 = x2 + 32 – 2(3)(x)cos(100°)
52 = x2 + 32 – 2(3)(x)cos(140°)
x2 = 52 + 32 – 2(5)(3)cos(100’)
x2 = 52 + 32 – 2(5)(3)cos(140°)
Answer:
D. x2 = 52 + 32 – 2(5)(3)cos(140°)
Step-by-step explanation:
The equation measures the cyclist's distance, x, from the starting point will be x²=5²+3²-2(5)(3)cos(140°). Option B is corect.
What is the distance?Distance is a numerical representation of the distance between two objects or locations.
The distance can refer to a physical length or an estimate based on other factors in physics or common use. |AB| is a symbol for the distance between two points A and B.
Distance is measured in the meter, centimeter, miles, nautical mile, feet, etc. The unit of distance is most important to find it.
The distance, x, from the starting point is;
From the cos law ;
x² = a² +b²-2ab cosΘ
From the digrame it is obtained that;
a =5
b =3
Θ = 180 ° +70° -30°
Θ = 180°- 40°
Θ = 140°
Substitute the values;
x² = a² +b²-2ab cosΘ
x²=5²+3²-2(5)(3)cos(140°)
The equation measures the cyclist's distance, x, from the starting point will be x²=5²+3²-2(5)(3)cos(140°).
Hence option B is corect.

Jasper and Corey have saved up a total of $78.00. Jasper has saved 6 dollars more than twice as much as
Corey. How much has Corey saved?
Answer:
24
Step-by-step explanation:
Corey has saved an amount of 24 dollars, if they have saved up a total of $78.00.
What is an equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
Let's assume that Corey has saved an amount of x dollars.
Given that Jasper and Corey have saved up a total of $78.00.
Jasper has saved 6 dollars more than twice as much as
Corey.
As per the given condition, the algebraic form is:
(6 + 2x) + x = 78.
Rearrange the terms of variables of x in the above equation,
6 + 2x + x = 78
Apply the addition operation,
6 + 3x = 78
Subtract 6 from both sides in the equation,
3x = 72
Now divide both sides by 3 in the equation,
x = 24
Therefore, Corey has saved an amount of 24 dollars.

What is 3x-2y=24 in slope intercept form??
this doesn't make sense how do you find the y and x and slope
Answer: 3x-2y=24 in slope intercept form is [tex]y=\frac{2}{3}x -12[/tex]
The graph of the equation is in the attachment
Step-by-step explanation: Slope intercept form is y = mx + b
m is the slope b is the y-intercept x is the "input" in the equation y is the "output" or the y-value in the graph for a given x-value.
You need to rearrange the standard form to slope-intercept to isolate y on the left side of the equation.
3x - 2y = 24 Standard form. Subtract 3x from both sides.
-2y = -3x + 24 divide both sides by -2
-2y/-2 = -3x/-2 + 24/-2 . Simplify.
y = 3x/2 - 12 .
To clarify the slope as a fraction
[tex]y=\frac{2}{3}x -12[/tex]

Answer:
[tex]\frac{2}{3}[/tex]
Step-by-step explanation:
To find the slope of a line, we would need to use the equation [tex]\frac{y_2-y_1}{x_2-x_1}[/tex] where two given points are [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex]. These points can be any two points that fall on the line.
In the graph, two points we can use to find the slope is (1, 2) and (-2, 0).
[tex]\frac{y_2-y_1}{x_2-x_1}\\\\\frac{0-2}{-2-1} \\= \frac{-2}{-3} \\= \frac{2}{3}[/tex]
Therefore, the slope of the line is [tex]\frac{2}{3}[/tex].

c
Step-by-step explanation:
Given the2 equations
y = x + 4 → (1)
x + y = 2 → (2)
Substitute y = x + 4 into (2)
x+ x + 4 = 2
2x + 4 = 2 ( subtract 4 from both sides )
2x = - 2 ( divide both sides by 2 )
x = - 1
Substitute x = - 1 into (1) for corresponding value of y
y = - 1 + 4 = 3
solution is (- 1, 3 ) → c
Cathy would like to have accumulated $25,000 on her IRA account in 5 years. The return is 3.1%. How much should Cathy deposit in her account annually?
$1,329.94
$2,711.73
$4,699.46
$5,000.00
Answer:
Annual deposit= $4,699.46
Step-by-step explanation:
Giving the following information:
Future value (FV)= $25,000
Number of periods (n)= 5 years
Interest rate (i)= 3.1% = 0.031
To calculate the annual deposit, we need to use the following formula:
FV= {A*[(1+i)^n-1]}/i
A= annual deposit
Isolating A:
A= (FV*i)/{[(1+i)^n]-1}
A= (25,000*0.031) / [(1.031^5) - 1]
A= $4,699.46

The regular price for Super Fly Sneakers at Shoes R' Us is $100. The shoes are on sale for 35% off the regular price. Jazmine uses a coupon for an additional 25% off the sale price. How much will Jazmine pay for her Super Fly Sneakers after both discounts
Answer:
$48.75
that is the answer
Answer:
Jazmine will pay only $40 for both discounts.
Step-by-step explanation:
First we need to add the two discounts, 35% + 25% = 60%.
Now we need to convert 60% into a decimal, which is 0.60.
Now we need to multiply the regular price, $100, by 0.60.
$0.60 × $100 = $60.
Now we subtract the discount by the amount, $100 - $60 = $40.
