Answers
It's important to know that proper fractions like 2/3 are between 0 and 1, specifically, 2/3 is equal to 0.67.
Now, we have three numbers, 0.67, 1.75, and -0.75. If we organize the numbers from least to greatest we have -0.75, 0.67, and 1.75. Then, we use the inequality symbols to express this order.
[tex]-0.75<\frac{2}{3}<1.75[/tex]The symbols are telling us that -0.75 is less than 2/3, and 2/3 is less than 1.75.
Now, let's graph this relation between the three numbers.

brain's tent is a triangular prism how much fabric was used make the tent
Answers
We can think of the tent as the sum of two rectangles (both sides) and two triangles (front and back)
Each ofthe rectangles are 12ft lenght and 8.6ft height, so their area is:
Area of the rectangle = 12x8.6 = 103.2 square feet, since they are two, 103.2 x 2 = 206.4 square feet
Each of the triangles have a base of 10ft and a height of 7 ft, so their area is:
Area of the triangle = (10 x 7)/2 = 70/2 = 35, since they are also two, 35 x 2 = 70 square feet
Total area of the tent = 206.4 + 70 = 276.4 square feet

The inequality in standard form that describes the situation is 15x + 20y ≥ 554.
What is the inequality equation?Here are inequality signs and what they mean:

≥ means greater than or equal to
≤ less than or equal to
If the ounces of water have to be at least 554 ounces, it means that the water taken can be equal or greater than 554 ounces. Thus the sign to be used is ≥.
The total ounces of water taken if a function of the capacity of small bottles and the number of small bottles taken and the capacity of large bottles and the number of large bottles taken.
(capacity of a small bottle x number of small bottles) + (capacity of large bottles x number of large bottles) ≥ 554 ounces

Answers
y = 3
Explanation:Equation of line formula:
y = mx + b
m = slope
b = y-intercept
Points: (-7,3) and (-4,3)
we apply the slope formula:
[tex]m\text{ = }\frac{y_2-y_1}{x_2-x_1}[/tex][tex]\begin{gathered} x_1=-7,y_1=3,x_2=-4,y_2\text{ = }3 \\ m\text{ = }\frac{3-3}{-4-(-7)}=\frac{0}{-4+7} \\ m\text{ = 0/3} \\ m\text{ = 0} \end{gathered}[/tex]To get c, we use any of the points in the equation of line
Using point (-7, 3) = (x, y)
y = mx + b
3 = 0(-7) + b
3 = 0 + b
3 = b
The equation of line for the given points:
y = 0(x) + 3
y = 0 = 3
y = 3
Hence, the equation is y = 3

The equation of the parabola is y = (x + 2)² - 2, and the value of f(-1) is -1 after plugging x = -1 in the function.
What is a parabola?It is defined as the graph of a quadratic function that has something bowl-shaped.
(x - h)² = 4a(y - k)
(h, k) is the vertex of the parabola:
a = √[(c-h)² + (d-k²]
(c, d) is the focus of the parabola:
From the graph the vertex form of the parabola:
(-2, -2)
h = -2
k = -2
The vertex form of the parabola:
y = a(x - h)² + k
y = a(x + 2)² - 2
Plug x = 0
y = 2
a = 1
y = (x + 2)² - 2
Or
f(x) = (x + 2)² - 2
f(-1) = (-1 + 2)² - 2
f(-1) = -1
Thus, the equation of the parabola is y = (x + 2)² - 2, and the value of f(-1) is -1 after plugging x = -1 in the function.

The percentage of profit / selling price markup = 24.8 % , by rounding to nearest tenth.
What is profit?If the selling price is higher than the cost price, the difference between the two is referred to as profit. If the selling price is less than the cost price, the difference is referred to as the loss.Given this,
The seller's cost price is 210 dollars.
The seller's selling price is 279.30$.
We know that ,
Profit = selling price - cost price.
so, Profit = 279.30$ - 210$
= 69.3$.
To find the profit,
Profit /Selling Price Markup = (Profit/Selling Price)*100 .
-=> (69.3 / 279.30) x 100 = 24.81%

We need to solve an inequality given in the form:
[tex]\frac{x}{-6}\ge-20[/tex]So we need to isolate "x" on one side to the inequality symbol.
In order to do that, we need to multiply both sides by the number "-6" (which will cancel out the denominator that "x" has). Bit we need to recall that when we multipkynor divide by a negative number boths sides of an inequality, the symbol flips direction. having that in mind, we proceed to multiply and solve for "x":
[tex]\begin{gathered} \frac{x}{-6}\ge-20 \\ x\leq(-20)\cdot(-6) \\ x\leq120 \end{gathered}[/tex]So the answer is: all real x-values less than or equal to 120.
If we need to give the answer in graphic form, we draw a number line with the origin (0), and mark on the right of it a point that we name "120". Then we highlight the line from the point 120 towards the left, and we make sure that we draw a solid dot on the 120 point mark to indicate that the point is included in the set.

Let f(x) = 2x + 7 and g(x) = 3(2x +7). The y-intercept of g is Choose... the y-intercept of f, and the x-intercept of g is Choose... the x-intercept of f.
Answers
The y-intercept of .f(x) = 2x + 7 is 7; its x-intercept is -7/2.
The y-intercept of .f(x) = 2x + 7 is 7; its x-intercept is -21/6.
What is the Y-intercept and the X-intercept of a Function?A function is expressed in slope-intercept form as .f(x) = mx + b, where the y-intercept is represented by the value of b.
On the other hand, to determine the value of the x-intercept for a function, .f(x) = mx + b, substitute .f(x) = 0 into the equation .f(x) = mx + b and solve for the value of x in the equation.
Find the y-intercept and the x-intercept of .f(x) = 2x + 7:
y-intercept of the function (b) = 7
To find the x-intercept, substitute .f(x) = 0 into f(x) = 2x + 7:
0 = 2x + 7
Subtract 7 from both sides
0 - 7 = 2x + 7 - 7
-7 = 2x
Divide both sides by 2
-7/2 = 2x/2
-7/2 = x
x = -7/2
Therefore, the x-intercept is: -7/2.
Find the y-intercept and the x-intercept of g(x) = 3(2x +7):
g(x) = 3(2x +7)
g(x) = 6x + 21
The y-intercept is: 21.
Find the x-intercept by substituting g(x) = 0 into g(x) = 6x + 21:
0 = 6x + 21
-21 = 6x
-21/6 = 6x/6
-21/6 = x
x = -21/6.
x-intercept is: -21/6.

Last year, Yoko had $10,000 to invest. She invested some of it into an account that paid 10% simple interest per year, and she invested the rest in an account that paid 6% simple interest per year. After one year she received a total of $640 in interest. How much did she invest in each account?
Answers
Final answer:
At 10% interest, $1 000 was invested.
At 6% interest, $9 000 was invested.
Let "x" be the amount invested at 10%. The annual interest for this investment would be $ 0.1x
Now, the investment at 6% is (10 000 - x), and it would have an annual interest of 0.06(10 000 - x)
We will use the following equation to solve for this
[tex]interest_1+interest_2=totalinterest[/tex]interest 1 = 0.1x
interest 2 = 0.06(10 000 - x)
total interest = 640
Substitute these values
[tex]interest_1+interest_2=totalinterest[/tex][tex]0.1x+0.06(10000-x)=640[/tex]Solve for x
[tex]0.1x+0.06(10000-x)=640[/tex][tex]0.1x-0.06x=640-\lbrack(0.06)(10000)\rbrack[/tex][tex]0.04x=640-600[/tex][tex]0.04x=40[/tex]Divide both sides by 0.04
[tex]\frac{0.04x}{0.04}=\frac{40}{0.04}[/tex][tex]x=1000[/tex]Since the investment at 6% is equal to 10000-x,
[tex]interest_2=10000-x[/tex][tex]=10000-1000[/tex][tex]=9000[/tex]Final answer:
At 10% interest, $1 000 was invested.
At 6% interest, $9 000 was invested.
To check,
[tex]0.1x+0.06(10000-x)=640[/tex][tex]0.1(1000)+0.06(10000-(1000))=640[/tex][tex]640=640[/tex]Write an equation in standard form of the line that passes through the point (-2,0) and has the slope of m=-2.
Answers
The equation in standard form of the line is y+2x+4 = 0.
A straight line's general equation is y = mx + c, where m denotes the gradient and y = c denotes the point at which the line crosses the y-axis. On the y-axis, this value c is referred to as the intercept.
Y = mx + c represents the expression of a straight line with slope m and intercept c on the y-axis.Given the variety of geometries in modern mathematics, the idea of a line is directly related to how the topology is described. In analytic geometry, for example, a line in the plane is frequently described as the collection of points whose coordinates satisfy a particular linear equation, whereas in a more abstract context, such as contact geometry, a line may be an autonomous object, separate from the points.We know that the standard form a straight line equation is given by
y-q = m(x-p) where (p,q) is a point on the line and m is the slope.
Therefore
y-0 = -2(x-{-2})
or, y = -2x -4
or, y + 2x + 4 = 0
Therefore the equation of the straight line is y + 2x + 4 = 0 .
