Answer:

The answer is 165 in.

Step-by-step explanation:

The first shape (On the right) has a length of 3in. If you look at the top. and the height is 9in. Now you can find the width by looking at the other shape on the left and its width is 3in. Good thing the width on that shape matches the width on the right shape. so now you multiply 3, 3, and 9 and you get 81.

Now you look at the shape on the left. We already know the width which is 3in. and the height is 4in. to find the length don't look at the 10in. the 10 is the 1st and 2nd shape put together. look at the top of the shape on the left and there is a 7. That 7 is your length. now you multiply 7, 3, and 4 and you should get 84. Now you add 84 and 81 and you are left with the answer of 165in squared.

The total surface area of the two cubical figures is A = 224 inches²

A cuboid is defined as a three-dimensional shape, that has six rectangular faces, eight vertices and twelve edges

The total surface area of the cuboid is given by the formula

Surface Area = 2 ( LH + LW + HW )

where ,

Length of the cuboid = L

Width of the cuboid = W

Height of the cuboid = H

Given data ,

Let the surface area of the figure be represented as A

Now , let the surface area of the first cuboid be A₁

And , let the surface area of the second cuboid be A₂

On simplifying the equation , we get

The surface area of the cuboid A₁ = ( 3 x 4 ) + 2 ( 7 x 3 ) + 2 ( 7 x 4 )

The surface area of the cuboid A₁ = 12 + 42 + 56

The surface area of the cuboid A₁ = 110 inches²

And ,

The surface area of the cuboid A₂ = 2 ( 3 x 3 ) + 3 ( 9 x 3 ) + ( 5 x 3 )

The surface area of the cuboid A₂ = 18 + 81 + 15

The surface area of the cuboid A₂ = 114 inches²

So , the total surface area of the figure A = surface area of the cuboid A₁ + surface area of the cuboid A₂

The total surface area of the figure A = 110 inches² + 114 inches²

The total surface area of the figure A = 224 inches²

Hence , the total surface area of the figure A = 224 inches²

After evaluating the given information about the algebraic and graphed functions, we can conclude that the algebraic function f(x) = -5x^2 - 8x, which is a downward-opening parabola, has a greater maximum value than the graphed function in question. Therefore, the correct answer is option A.

To compare the algebraically expressed function f(x) = -5x^2 - 8x with a given graphed function, we need to look at their respective shapes and key features. Since f(x) is a quadratic function with a negative coefficient for the x^2 term, it is a downward-opening parabola that will have a maximum value. Without more information about the graphed function, we can still analyze the given description to ascertain its nature.

Based on the given statements, let's identify which function has a greater maximum or a lower minimum value:

In conclusion, given that f(x) = -5x^2 - 8x is a downward-opening parabola with a definite maximum value, and none of the provided statements about the graphed function suggest it has a maximum value higher than a constant value or a parabola, we can conclude that:

The algebraic function has a greater maximum value, so the correct answer would be option A.

The graphed function has a greater maximum value. The algebraic function's downward-opening parabola indicates a maximum value, and the graphed function's characteristics suggest it may have a higher maximum (option c).

To determine the maximum values of the algebraic function [tex]\(f(x) = -\frac{5}{2}x^2 - 8x\)[/tex] and the graphed function, we need to analyze the coefficient of the quadratic term in the algebraic expression. The quadratic term is [tex]\(-\frac{5}{2}x^2\)[/tex], and since the leading coefficient is negative, the parabola opens downwards. This means that the algebraic function has a maximum value, and the coefficient [tex]\(-\frac{5}{2}\)[/tex] determines the concavity.

Comparatively, the graphed function on the graph may have a different leading coefficient, affecting the concavity. If the graphed function has a positive leading coefficient, it opens upwards, suggesting a minimum value. Conversely, if it has a negative leading coefficient, it opens downwards, indicating a maximum value (option c).

In the case of the given options, statement C is correct. The graphed function has a greater maximum value because the leading coefficient of the quadratic term in the algebraic function is negative, resulting in a downward-opening parabola with a maximum point. Therefore, the graphed function, depending on its characteristics, may exhibit a greater maximum value.

The complete question of the given answer is:

Compare the algebraically expressed function [tex]\(f(x) = -\frac{5}{2}x^2 - 8x\)[/tex] to the function shown in the graph to determine which statement is true.

A) The algebraic function has a greater maximum value.

B) The algebraic function has a lower minimum value.

C) The graphed function has a greater maximum value.

D) The graphed function has a lower minimum value."

Answer:  option C

[tex]x=-10\\y=11[/tex]

Step-by-step explanation:

You can apply the elimination method:

- Multiply the second equation by 3.

- Add both equations to cancel out the variable x.

- Solve for y:

[tex]\left \{ {{-3x+5y=85} \atop {(3)(x+4y)=34(3)}} \right.\\\\\left \{ {{-3x+5y=85} \atop {3x+12y=102}} \right.\\-------\\17y=187\\y=11[/tex]

- Substitute y=11 into any of the original equations ans solve for x. Then:

[tex]x+4(11)=34\\x=34-44\\x=-10[/tex]

The answers are:

[tex]x=-10\\y=11[/tex]

We can solve system of equations using several methods, but the simplest way to solve it, is isolating variables in terms of another variables.

So, isolating "x" from the second equation we have:

[tex]x + 4y =34\\x=34-4y[/tex]

Then, substituting "x" into the first equation, we have:

[tex]-3(34-4y) +5y =85\\-102+12y+5y=85\\17y=85+102\\17y=187\\y=\frac{187}{17}=11\\[/tex]

Now, substituting "y" into the second equation to calculate "x", we have:

[tex]x + 4(11) =34\\x=34-44\\x=-10[/tex]

So, the solutions for the system of equations are:

[tex]x=-10\\y=11[/tex]

Answer:

28.4

Step-by-step explanation:

Translate the statement into an equation, and then solve the equation.

Let x be the number we are looking for.

155% of what number is 44?

155% of x is 44

In math "of" usually means multiplication.

155% * x = 44

To change a percent to a decimal, divide by 100 which means move the decimal point 2 places left. 155% = 155/100 = 1.55

1.55x = 44

Divide both sides by 1.55 to solve for x.

1.55x/1.55 = 44/1.55

x = 28.4

Applying the distributive property

taking the outer term and multiplying it by each term inside the parenthesis

so

[tex]8(5x-9)=8*5x-8*9[/tex]

[tex]40x-72[/tex]

Answer:

[tex]8(5x - 9) = 40 x - 72[/tex]

Step-by-step explanation:

Let a, b, and c be any real number. Then

[tex]a(b + c) = ab + bc[/tex]

This is called the distributive property.

The given expression is

[tex]8(5x - 9)[/tex]

Or

[tex]8(5x + - 9)[/tex]

Let a=8, b=5x and c=-9

We apply the distributive property to obtain:

[tex]8(5x - 9) = 8 \times 5 x + 8 \times - 9[/tex]

We simplify to get:

[tex]8(5x - 9) = 40 x - 72[/tex]

Answer:

The function intersects the y-axis at point (0.9) (vertex)

Step-by-step explanation:

we know that

The equation of a vertical parabola into vertex form is equal to

[tex]y=a(x-h)^{2}+k[/tex]

where

(h,k) is the vertex of the parabola

if a>0 then the parabola open upward (vertex is a minimum)

In this problem we have

[tex]y-x^2=9[/tex] -----> [tex]y=x^2+9[/tex]

This is a vertical parabola open upward

The vertex is the point (0,9)

The vertex is a minimum

see the attached figure to better understand the problem

The graph does not intersect the x-axis (the function has no real roots)

The function intersects the y-axis at point (0.9) (vertex)

If Carmen sold 600 liters of soda, then he would have sold 600000 milliliters of soda. 1 liter= 1000 milliliters

A) To find A in terms of B, we need to find A = xB. One given is A = 12 and B = 3. We substitute, which gives us 12 = x4. Divide both sides by 4, which gives us x = 3. This means that A = 3B.

B) For this, we can just plug in 5 as B in our equation. A = 3*5 -> A = 15.

C) We can plug in A as 36. 36 = 3B -> B = 12.

A.) The formula for A in terms of B is A = 4B. B.) When B = 5, A = 20. C.) When A = 36, B = 9.

A.) To find the formula for A in terms of B, we can set up a proportion using the given values. Since A is directly proportional to B, we can write the proportion as A/B = k, where k is the constant of proportionality. Substituting the values A = 12 and B = 3, we have 12/3 = k. Solving for k, we find k = 4. Therefore, the formula for A in terms of B is A = 4B.

B.) To find the value of A when B = 5, we can substitute B = 5 into the formula A = 4B. A = 4(5) = 20.

C.) To find the value of B when A = 36, we can rearrange the formula A = 4B to solve for B. Dividing both sides by 4, we get B = A/4. Substituting A = 36, we have B = 36/4 = 9.

n = number of book reports

6 + 7n = 90

7n = 84

n = 12

12 book reports

stan needs to report at least 12 books to get passing marks.

In mathematics, inequalities specify the connection between two non-equal numbers. Equal does not imply inequality. Typically, we use the "not equal sign ()" to indicate that two values are not equal. But several inequalities are utilized to compare the numbers, whether it is less than or higher than.

Given,  stan needs 90 points to get a passing grade in the class. He already has6 points.

Let "x " be the number of books he Reports.

Since each book report is worth 7 points.

Thus, if he reports x books he will get = 7 * x points

Since he already has 6 points

So, the total points stan has for reporting x books = 7x + 6

Thus inequality,

7x + 6 ≥ 90

=> 7x + 6 ≥ 90

=> 7x ≥ 84

=> x ≥ 12

therefore, stan needs to report at least 12 books to get passing marks.

Answer:

18 km/h

Step-by-step explanation:

Let S km be the distance between ports M and N, x km/h be the speed of the motorboat in still water. Then x-2 km/h is the speed of the motorboat upstream and x+2 km/h is the speed of the motor boat downstream.

1. The motorboat traveling downstream covers the distance between port M and port N in 6 hours, then

[tex]\dfrac{S}{x+2}=6[/tex]

2. Once, the motorboat stopped 40 km before reaching N, turned around, and returned to M. This took the motorboat 9 hours. Then

[tex]\dfrac{S-40}{x+2}+\dfrac{S-40}{x-2}=9[/tex]

From the first equation [tex]S=6(x+2)=6x+12.[/tex] Substitute it into the second equation:

[tex]\dfrac{6x+12-40}{x+2}+\dfrac{6x+12-40}{x-2}=9,\\ \\\dfrac{6x-28}{x+2}+\dfrac{6x-28}{x-2}=9.[/tex]

Now

[tex]\dfrac{(6x-28)(x-2)+(6x-28)(x+2)}{(x-2)(x+2)}=9,\\ \\(6x-28)(x-2+x+2)=9(x^2-4),\\ \\(6x-28)\cdot 2x=9x^2-36,\\ \\12x^2-56x-9x^2+36=0,\\ \\3x^2-56x+36=0,\\ \\D=(-56)^2-4\cdot 3\cdot 36=2704,\\ \\x_{1,2}=\dfrac{56+\sqrt{2704}}{2\cdot 3}=\dfrac{56\pm52}{6}=\dfrac{2}{3},\ 18.[/tex]

The speed of the motorboat cannot be less than the speed of the current, thus, x=18 km/h.

The speed of the motorboat in still water if the speed of the current is 2 km/hour is 18 km/hour.

Suppose the distance between port M and N =d

Suppose the speed of the motorboat in still water =x

The speed of the current =2 km/h (given)

So, the downstream speed of the boat = (x+2)

Upstream speed of the boat = (x-2)

Speed is the distance covered in unit time.

According to the question, a motorboat travelling downstream covers the distance between port M and port N in 6 hours.

This means, [tex]\frac{d}{x+2} =6[/tex]

So, [tex]d=6(x+2)[/tex]

Distance covered by the motorboat when the motorboat stopped 40 km before reaching N = d-40

=[tex]6(x+2)-40[/tex]

=[tex]6x-28[/tex]

So, [tex]\frac{6x-28}{x+2} + \frac{6x-28}{x-2} =9[/tex]

So, [tex]x=18[/tex]

[tex]x=\frac{2}{3}[/tex](not possible)

Therefore, the speed of the motorboat in still water if the speed of the current is 2 km/hour is 18 km/hour.

The map tells you 1 inch = 0.5 miles.

Multiply each dimension on the map by 0.5 to get the miles, then add them together:

House to Sports store = 2 x 0.5 = 1 mile.

Sports store to Jay's house = 3.75 x 0.5 = 1.875 miles.

Jay's house to park = 1.5 + 0.5 = 2 inches x 0.5 = 1 mile.

Total distance = 1 + 1.875 + 1 = 3.875 miles.

The total distance covered in miles is; 3.875 miles

From the map, we see that;

Explanation:

The slope of a line is rise over run, where the rise is the change in y value and the run is the change in x. Since there is no change in x when a line is parallel to the y-axis, any slope would mean you would divide by 0.
