2÷9=2/9Billie buys materials for a project at a fabric store. She has $16.95 to spend. She buys fabric for $8.69, craft glue for $1.95, and craft paper for $4.29. How much money does she left after she pays for the items?
Final answer:
Billie has $2.02 left after buying fabric, craft glue, and craft paper, which in total cost her $14.93 from her initial $16.95.
Explanation:
To find out how much money Billie has left after purchasing her items, we need to calculate the total cost of the items and subtract it from the amount she had initially.
Fabric cost: $8.69
Craft glue cost: $1.95
Craft paper cost: $4.29
We add these amounts together to find the total cost of the items:
$8.69 (fabric) + $1.95 (glue) + $4.29 (paper) = $14.93.
Now, we subtract the total cost of items from the amount she had to start with:
$16.95 - $14.93 = $2.02.
Therefore, Billie has $2.02 left after her purchases.

Jose is going to order wrenches for his hardware store. He can order four different types and the table shows the profit margin for each type in tens of dollars and the probability. Which wrench should he order?
Answer:
B
Step-by-step explanation:
The expected value of profit margin is the sum of the product of profit margin and probability.
Wrench A:
... 10×.05 +20×.6 +30×.2 +40×.15 = 0.5 +12 +6 +6 = 24.5
Wrench B:
... (20+40)×.3 +(30+50)×.2 = 18 +16 = 34
Wrench C:
... 15×.4 +30×.5 +(45+60)×.05 = 6 +15 +5.25 = 26.25
Wrench D:
... 5×.2 +10×.4 +15×.15 +20×.25 = 1 +4 +2.25 +5 = 12.25
___
Clearly, Wrench B has the greatest expected profit margin. That would be the one Jose should order if he's trying to maximize his profit.
Find the equation of the line parallel to the graph of 14x-7y=1 that passes through the point at (-2,4)
The equation of the line parallel to the graph of 14x - 7y = 1 that passes through the point at (-2, 4) is y = 2x + 8. The correct option is C.
To find the equation of the line parallel to the graph of 14x - 7y = 1 that passes through the point at (-2, 4), we first need to determine the slope of the given line. We can write the given equation in slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept.
Starting with 14x - 7y = 1, we solve for y:
14x - 7y = 1-7y = -14x + 1y = 2x - 1/7The slope of the original line is 2, so a line parallel to it will also have a slope of 2. Using the point-slope form of a line equation, y - [tex]y_1[/tex] = m(x - [tex]x_1[/tex]), and the point (-2, 4), we get:
y - 4 = 2(x + 2)y - 4 = 2x + 4y = 2x + 8Therefore, the equation of the line parallel to 14x - 7y = 1 and passing through (-2, 4) is y = 2x + 8.

[tex]\begin{aligned}A) \:& y=2 x+3 \\B)\: & y=\frac{1}{2} x+3 \\C) \:& y=2 x+8 \\D) \:& y=-\frac{1}{2} x-3\end{aligned}[/tex]
An aquarium has a length of n^ 2 +2 inches, a height of n + 5 inches, and a width of 10 inches. What is the volume, in cubic inches, of the aquarium, in terms of n ?
The formula of a volume of a rectangle prism:
[tex]V=lwh[/tex]
l - length
w - width
h - height
We have
[tex]l=n^2+2;\ w = 10,\ h=n+5[/tex]
Substitute:
[tex]V=(n^2+2)(10)(n+5)=(10n^2+20)(n+5)\\\\=(10n^2)(n)+(10n^2)(5)+(20)(n)+(20)(5)\\\\=10n^3+50n^2+20n+100[/tex]
Answer: V = (10n³ + 50n² + 20n + 100) in³The volume of the aquarium in terms of n is calculated by multiplying its length (n2 +2 inches), width (10 inches), and height (n + 5 inches) giving the formula V = (n2 + 2) imes (n + 5) imes 10, which expands to V = 10n3 + 60n2 + 20n + 100 cubic inches.
We use the formula V = length times width times height, where the volume V is the space inside the aquarium. The question provides the dimensions of the aquarium in terms of n: the length (n2 +2 inches), height (n + 5 inches), and width (10 inches).
To calculate the volume, simply multiply the dimensions together:
Length: n2 + 2 inchesHeight: n + 5 inchesWidth: 10 inchesVolume, V = (n2 + 2) imes (n + 5) imes 10
Expanding the expression gives us the volume V in cubic inches as a function of n:
V = 10n3 + 60n2 + 20n + 100 cubic inches
Identify all the hyperbolas which open horizontally
Answer:
The hyperbolas which open horizontally are:
(x+2)^2/3^2-(2y-10)^2/8^2=1
(x-1)^2/6^2-(2y+6)^2/5^2=1
Step-by-step explanation:
A hyperbola with equation of the form:
(x-h)^2/a^2-(y-k)^2/b^2)=1 opens horizontally
Then, the hyperbolas which open horizontally are:
(x+2)^2/3^2-(2y-10)^2/8^2=1
(x-1)^2/6^2-(2y+6)^2/5^2=1
Answer:
[tex]\frac{(x-2)^2}{3^2}-\frac{(2y-10)^2}{8^2}=1[/tex]
and
[tex]\frac{(x-1)^2}{6^2}-\frac{(2y+6)^2}{5^2}=1[/tex]
Step-by-step explanation:
There are 2 types of hyperbolas:
Horizontal:
[tex]\frac{(x-h)^2}{a^2}-\frac{(y-k)^2}{b^2}=1[/tex]
Vertical:
[tex]\frac{(y-k)^2}{a^2}-\frac{(x-h)^2}{b^2}=1[/tex]
If the x term is positive then parabola is horizontal.
If the y term is positive then parabola is vertical.
so, only first two equations are in which x term is positive.
hence, equations are
[tex]\frac{(x-2)^2}{3^2}-\frac{(2y-10)^2}{8^2}=1[/tex]
and
[tex]\frac{(x-1)^2}{6^2}-\frac{(2y+6)^2}{5^2}=1[/tex]

Answer:
Max for g(x) is 3
Max for f(x) is 2
Step-by-step explanation:
The maximum value of a function is the highest value on the graph of the function. It is the greatest value of the function and is always a y value. We can see on the graph that the blue function peaks at 3. The max is 3.
A normal sine or cosine without any transformations has the max of 1. We can see in the equation for f(x) that there is a vertical stretch of 2. So the max here is 2(1)=2.
A health food store makes trail mix using dried fruit and nuts. The cost of the dried fruit is $2.50 per pound and the cost of the nuts is $2.00 per pound the total cost to make the trail mix is $225. If the total cost can be represented by the equation 2.5x+2y=225 what does the term 2.5x represent?
In the equation 2.5x + 2y = 225, the term 2.5x represents the cost of dried fruit, with 2.5 being the cost per pound.
In the provided equation 2.5x + 2y = 225, where x stands for the pounds of dried fruit and y represents the pounds of nuts, the term 2.5x signifies the cost associated with the dried fruit in making the trail mix.
The coefficient 2.5 represents the cost per pound of dried fruit, which is $2.50. Therefore, multiplying the pounds of dried fruit (x) by the cost per pound (2.5) gives the total cost of the dried fruit in the trail mix. In essence, 2.5x calculates the financial contribution of the dried fruit to the overall cost of producing the trail mix.
For example, if there are 10 pounds of dried fruit (x = 10), then 2.5 times 10 equals 25, representing the cost, in dollars, of the dried fruit in the trail mix. This interpretation extends to any quantity of dried fruit used in the trail mix.
In summary, the term 2.5x in the equation 2.5x + 2y = 225 specifically denotes the cost associated with the pounds of dried fruit (x) used in producing the trail mix.

A Plummer is fixing a pipe with an interior diameter of 0.63 inches. He buys a replacement pipe that must fit inside the old pipe. He uses plumbing tape that will fill 0.15 inches off the space between the two pieces of pipe. The new pipe must be 0.1 inches smaller than the old pipe and tape so that it can fit inside. What is the largest interior diameter pipe he can buy that will still fit inside the old pipe?
The largest interior diameter of the new pipe that would still fit inside the old one is 0.38 inches, after taking into account the thickness of the plumbing tape and additional space requirement.
Explanation:The plumber is attempting to fit a new pipe into an old pipe with an interior diameter of 0.63 inches. We need to take into account the thickness of the plumbing tape that will add an extra 0.15 inches to the diameter, as well as the requirement that the new pipe must be 0.1 inches smaller to fit inside the old pipe.
To calculate the largest interior diameter the new pipe can have, we should do the following:
First, start with the old pipe's diameter, which is 0.63 inches. Deduct the thickness of the plumbing tape. This gives us 0.63 - 0.15 = 0.48 inches. Then, subtract the additional 0.1 inch requirement to provide space for the new pipe to fit. This gives us 0.48 - 0.1 = 0.38 inches.
So, the largest interior diameter of the new pipe that will fit in the old one is 0.38 inches.
