If your car gets 34 miles per gallon, how much does it cost to drive 320 miles when gasoline costs $3.40 per gallon?
The cost is $
(Simplify your answer. Round to the nearest cent as needed.)
Answer:
$31.96
Step-by-step explanation:
To find how many gallons you need, divide 320 by 34.
[tex]\frac{320}{34} =9.4 (rounded-to-the-nearest-cent)[/tex]
So now that we know we need 9.4 gallons, we multiply 9.4 times the price per gallon ($3.40)
9.4 x $3.40 = $31.96
Please help me on this homework assignment, 20 points to whoever can help me and give me a good answer. it is asking for the height and the bottom number under the 90 degree angle is 6.
Answer:
h = 3 sqrt(21)
or
h = 13.75
Step-by-step explanation:
The perimeter of the rhombus is 60 feet. Like a square, all the sides of a rhombus are equal. Therefore your first step is to find FK which is a side.
FK = 60/4 = 15 feet.
Now you can use the Pythagorean Theorem.
a^2 + b^2 = c^2
a = 6
b = height or = h
c = 15
6^2 + b^2 = 15^2
36 + b^2 = 225
b^2 = 225 - 36
b^2 = 189
sqrt(b^2)= sqrt(189)
b = sqrt(3 * 3 * 3 * 7) You can take out the square of 3 * 3 and make it 3.
b = 3 * sqrt(3*7)
b = 3 * sqrt(21)

The range of which function is (2.oo)?
y = 2x
y = 2(5x)
y=5X +2
y = 5x + 2
Answer: [tex]y = 5^x+2[/tex]
The 2 is not in the exponent.
=====================================================
Explanation:
As x gets smaller and smaller, going off into the negative direction forever, the expression [tex]5^x[/tex] will approach 0. This is because we're computing stuff like 5^(-1) = 1/5 = 0.2 and 5^(-2) = 1/25 = 0.04 and so on. The decimal values are approaching 0 but never actually arrive there. The range of [tex]y = 5^x[/tex] is [tex](0,\infty)[/tex]
Adding on the 2 at the end will shift everything up so that the range is now [tex](2,\infty)[/tex]. Refer to the graph below.
The parenthesis in interval notation mean we do not include that endpoint as part of the set. Saying something like [tex](2,\infty)[/tex] is the same as saying [tex]2 < y <\infty[/tex] when talking about the range.

Which of the following functions is even?
[tex]f(x) = -3x^2 + 4[/tex]
================================================
Explanation:
If all the exponents are even, then the polynomial function is even.
Choice A has a mix of even and odd exponents here, so choice A is neither even nor odd. We can rule this out.Choice B is the same story as choice A. So we can rule that out as well.Choice C has all of its exponents even. Therefore function C is an even function, and it's the final answer.Choice D is the same story as choice A. The only difference is the leading coefficient is positive.Your Gps shows that your friends house is 10.0 km away, as shown in the image below. but there is a big hill between your house and you dont want to bike the directly.

A rectangle has a length of 29 yards less than 9 times it’s width. If the area of the rectangle is 9418 square yards, find the length of the rectangle
Answer:
Step-by-step explanation:
w = w
L = 9*w - 29
Area = L*w
area = 9418
w * (9w - 29) = 9418
9w^2 - 29w - 9418 = 0 This monster factors, believe it or not
(9w + 277)(w - 34) = 0
9w + 277 =0
9w = - 277
w = -30.777778
w - 34 = 0
w = 34
The length = 9w - 29
L = 9*34 - 29
L = 306 - 29
L = 277
Check
Area = L * w
Area = 277 * 34
Area = 9418 just as it should.

Answer:
First, reflection over the x- axis, then a horizontal translation 3 units to the right and 3 units up.
Step-by-step explanation:
Order does not matter. The - before the (x-3) makes a reflection over the x-axis. Then, the -3 in the (x-3) makes the graph translate 3 units to the right, and the +3 is 3 units up.

The total cost of a desk and a stool is $86.50.
The stool costs $25.50 less than the desk.
How much does the stool cost?
Answer:
$30
Step-by-step explanation:
d + s= 86.50----------1
d - 25.50 = s
d - s=25.50------------2
1 - 2
(d-d) +(s-(-s))=86.50-25.50
2s=60
s=60/2=$30
The cost of a stool is $30.5 if the total cost of a desk and a stool is $86.50 and the stool costs $25.50 less than the desk.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
The total cost of a desk and a stool is $86.50.
The stool costs $25.50 less than the desk.
Let the cost of the desk is $d
Let the cost of the stool is $s
d + s = 86.50
s = d - 25.50
The above two equations represent two linear equations in two variables.
By solving by substitution method:
Plug s = d - 25.50 in the first equation
d + d - 25.50 = 86.50
2d = 86.50 + 25.50
2d = 112
d = 112/2
d = $56
s = 86.50 - 56
s = $30.5
Thus, the cost of a stool is $30.5 if the total cost of a desk and a stool is $86.50 and the stool costs $25.50 less than the desk.

Xander and Carly have a total of $12,000 to invest. If Zander tripled his money and Carly doubled her money, then they would have $31,000 to invest. How much money do each of them currently have? SOLVE this in TWO ways. Visually without variables and using algebra.
Answer:
Zander starts with 7,000; Carly starts with 5,000
Step-by-step explanation:
1 - Visually solving
Looking at the final value (31,000) one could interpret the sums of the numbers tripled and doubled respectively would need to equate to 31,000.
Taking off the additional zeros could also prove beneficial. To get 31, one of the numbers tripled or doubled would need to either be 11 or 21. 11 is a prime number, so that can be cancelled out. 7 multiplied by 3 (triple) produces 21.
12 - 7 = 5. Solving for the leftover 5 which would be doubled, you would get 10.
10 + 21 = 31.
2 - Algebra
x - Zander; y - Carly
To begin with you should need the initial formula.
x + y = 12,000
Your second formula would then take into consideration the changes made to x and y
3x + 2y = 31,000.
Using process of elimination or substitution, (either method works), you will find x = 7,000 and y = 5,000

Select the FALSE statement about the correlation coefficient (r).
a. The value of the correlation coefficient lies between-1 and 1.
b. The sign of the correlation coefficient tells us if the pair of variables is positively or negatively associated.
c. The correlation coefficient r = 0 shows that two variables are strongly correlated.
d. The correlation coefficient quantifies the strength of the linear relationship between two variables.
Answer:
C.
Step-by-step explanation:
Scatterplots with weak correlation coefficients are values near zero
The false statement about the correlation coefficient is r = 0 shows that two variables are strongly correlated.
What is Correlation?A statistical metric known as correlation illustrates how closely two variables are connected and how they tend to move in tandem. When two variables are positively correlated, they move in the same direction, and when they are negatively correlated, they move in the opposite way. To determine the degree and direction of the association between two variables, a correlation coefficient is utilized.
A correlation coefficient of -1 indicates a perfect negative correlation, a correlation coefficient of 1 indicates a perfect positive correlation, and a correlation coefficient of 0 indicates no correlation between the two variables.
Given data ,
The FALSE statement is:
c. The correlation coefficient r = 0 shows that two variables are strongly correlated.
A correlation coefficient of 0 means that there is no linear relationship between the two variables. It does not indicate the strength of the relationship.
A value of r = 0 indicates that there is no association between the two variables, whereas a value of r = 1 or r = -1 indicates a perfect positive or negative association, respectively.
