The correct answer is 44

Step-by-step explanation:

6(8)-4

48-4

44

Answer:

f(8) = 44

Step-by-step explanation:

Plug in 8 for x. Then evaluate the expression.

f(x) = 6x - 4

Where you see x, substitute it with 8.

f(x) = 6x - 4

f(8) = 6(8) - 4

f(8) = 48 - 4

f(8) = 44

Answer:

532m squared is the answer

Step-by-step explanation:

Split the shape into two shapes

one will be a square and the other one a triangle

1) since the length and the width of the square is 18m just Multiply

18x18=324m squared

2) look carefully the width of the square you split is equal to the base of the triangle, so you connect the 18 and the 8 together.

18+8=26m squared

3) Now solve the triangle since you know the height which is 16m squared.

A=lw/2

26x16=416

416 divided by 2 is 208

4) finally just Add

208+324=532m squared

Hopes this helps!

Final answer:

The sum of the first 5 prime numbers, which are 2, 3, 5, 7, and 11, is 28.

Explanation:

The sum of the first 5 prime numbers can be calculated by identifying those numbers and adding them together. The first 5 prime numbers are 2, 3, 5, 7, and 11. When we add these numbers, the sum is calculated as follows:

2 (the first prime number)

3 (the second prime number)

5 (the third prime number)

7 (the fourth prime number)

11 (the fifth prime number)

So, the sum would be 2 + 3 + 5 + 7 + 11 = 28.

Answer:  The required solution is (x, y) = (5, -2).

Step-by-step explanation:  We are given to solve the following system of equations :

[tex]2x+5y=0~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)\\\\3x-4y=23~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(ii)[/tex]

From equation (i), we have

[tex]2x+5y=0\\\\\Rightarrow 2x=-5y\\\\\Rightarrow x=-\dfrac{5}{2}y~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(iii)[/tex]

Substituting the value of x from equation (iii) in equation (ii), we get

[tex]3\times\left(-\dfrac{5}{2}y\right)-4y=23\\\\\\\Rightarrow -15y-8y=46\\\\\Rightarrow -23y=46\\\\\Rightarrow y=-\dfrac{46}{23}\\\\\Rightarrow y=-2.[/tex]

From equation (iii), we get

[tex]x=-\dfrac{5}{2}\times(-2)=5.[/tex]

Thus, the required solution is (x, y) = (5, -2).

Final answer:

To solve the simultaneous equations 2x+5y=0 and 3x-4y=23, you can multiply the first equation by 4 and the second by 5 to eliminate y, solve for x, and then substitute back to find y. The solution is x = 5 and y = -2.

Explanation:

To solve the simultaneous equations 2x+5y=0 and 3x-4y=23 using an algebraic method, one effective technique is to eliminate one of the variables to solve for the other. Let's eliminate y and solve for x.

Multiply the first equation by 4, and the second equation by 5, to make the coefficients of y equal but opposite in sign.

4(2x+5y) = 4(0) → 8x+20y = 0

5(3x-4y) = 5(23) → 15x-20y = 115

Add the two resulting equations to eliminate y.

8x + 20y + 15x - 20y = 0 + 115

23x = 115

x = 115/23

x = 5

Substitute x back into one of the original equations to solve for y. Using the first equation:

2(5) + 5y = 0

10 + 5y = 0

5y = -10

y = -2

The solution to the simultaneous equations is x = 5 and y = -2.

Answer:

≈ 11 ounces

Step-by-step explanation:

(This is the easiest method I can explain, there is probably a simpler one)

We can make a system of equations (x = oz. of pure oil, y = oz. of mixture):

x + y = 100 oz. -> y = 100 - x

x + 0.0451y = 0.15(100) -> x + 0.0451y = 15

Using substitution, we get that x + 0.0451(100 - x) = 15.

This is equal to x + 4.51 - 0.0451x = 15.

Subtracting both sides by 4.51 and combining like terms gets us

0.9549x = 10.49.

Dividing both sides gives us about 11 ounces.

Final answer:

To obtain 100 ounces of a 15% oil-gas mixture from a 4.51% oil-gas solution, 10.49 ounces of pure oil should be added to the solution.

Explanation:

To solve the problem of how many ounces of pure oil should be mixed with an oil-gas solution that is 4.51% oil to get 100 ounces of an oil-gas mixture that is 15% oil, we can use a simple mixture equation. Let's denote the unknown quantity of pure oil to be added as x ounces.

First, we calculate the amount of oil already present in the 4.51% oil-gas mixture. If we have a total of 100 ounces, the existing oil in the mixture is 4.51% of this, that is 4.51 / 100 × 100 = 4.51 ounces.

Next, we know that the final mixture will have to be 15% oil. Therefore, in 100 ounces of this mixture, we will need 15% oil, which is 15 / 100 × 100 = 15 ounces of oil.

To find out how much pure oil to add, we subtract the amount of oil already present in the mixture from the total amount of oil needed. So, x + 4.51 = 15, which gives us x = 15 - 4.51 = 10.49 ounces of pure oil needed to be added.

Step-by-step explanation:

Answer: The height of the right rectangular prism is 3.5 meters.

Step-by-step explanation:

To find the height of the right rectangular prism, you need to use the formula of the surface area of a rectangular prism, where [tex]l[/tex] is the lenght, [tex]w[/tex] is the width and the height is [tex]h[/tex]:

[tex]SA=2wh+2lw+2lh[/tex]

Substitute [tex]SA=286[/tex], [tex]l=10[/tex] and [tex]w=8[/tex] into the formula and solve for the height of the right rectangular prism:

[tex]SA=2wh+2lw+2lh\\\\286=2(8)h+2(10)(8)+2(10)h\\\\286=16h+160+20h\\\\286=160+36h\\\\286-160=36h\\\\126=36h\\\\\frac{126}{36}=h\\\\h=3.5\ m[/tex]

Final answer:

Using the surface area formula for a right rectangular prism, the height is calculated to be 3.5 meters after setting up the equation with given surface area, length, and width.

Explanation:

To find the height of a right rectangular prism with a given surface area, length, and width, we can use the surface area formula for a prism: SA = 2lw + 2lh + 2wh, where SA is the surface area, l is the length, w is the width, and h is the height.

Given that the surface area is 286 m2, the length is 10 m, and the width is 8 m, we can set up the equation 286 = 2(10)(8) + 2(10)h + 2(8)h.

Simplify this to 286 = 160 + 20h + 16h, which further simplifies to 286 = 160 + 36h. Subtracting 160 from both sides, we get 126 = 36h. Dividing both sides by 36 gives us h = 3.5 m.

Therefore, the height of the prism is 3.5 meters.

Answer:

D

Step-by-step explanation:

We can use the "vertical line test" to determine whether a given graph represents a function or not.  

If your vertical line intersects the graph in more than one place, the graph does NOT represent a function.  Thus, D does not represent a function, as a line drawn vertically thru this graph intersects the graph multiple times.

Graph A:  Note that if you draw a vertical line thru x = -2, your line will intersect the BLACK dot (-1 3/4, 0) and the EMPTY circle (-1 3/4, 3 1/4).  This is OK; this graph represents a function.

Answer:

Step-by-step explanation:

Make a table that has (x) on the left and (y)  on the right. There should be a slash between them. After that, you should place the numbers (1,2,3,4,5...) on the x column or on the left. Then times the x in  y = 2x - 1 with the numbers on the left and that would give the numbers on the right. Once you are done with that, then pair the numbers from the left to the right. Then simply graph it.

But always remember, left is (x) and right is (y)

Answer:

12.7

Step-by-step explanation:

The diagonal formula is x*sqrt(2) with x being one side length.

To find the side length divide the perimeter by 4.

That gives us 9.

Then, all you have to do is multiply that by the square root of 2 and then round.

To find the diagonal of a square with a perimeter of 36 inches, calculate the side length as 9 inches and apply the Pythagorean theorem, resulting in a diagonal length of approximately 12.7 inches.

The perimeter of a square is given as 36 inches, so to find the length of one side, we divide the perimeter by 4, since a square has four equal sides. Therefore, each side of the square is 36 inches ÷ 4 = 9 inches. To determine the length of the diagonal, we can apply the Pythagorean theorem in the square. The square's diagonal splits it into two right triangles, each with legs equal to the side of the square. If we denote the length of the diagonal as d and one side as s, the formula d² = s² + s² applies.

With both sides being 9 inches, this becomes d² = 9² + 9², leading to d² = 81 + 81 = 162. Taking the square root to find d, we get d = √162, which is approximately 12.7 inches when rounded to the nearest tenth.

Answer:

2.5 pounds

Step-by-step Explanation:

Since there are 16 ounces in a pound you do 40÷16, which would get you 2.49999.... But since you have to round to the nearest 10th, you would round to 2.5 pounds.

The quantity 40 ounces is equal to the quantity 2.5 pounds. Therefore, the correct answer is option A.

The given quantity is 40 ounces.

Metric Conversion refers to the conversion of the given units to desired units for any quantity to be measured.

We know that, there are 16 ounces in one pound.

Here, number of ounces = 40/16

= 20/8

= 10/4

= 5/2

= 2.5 pounds

Therefore, the correct answer is option A.

Answer:

Step-by-step explanation:

You can't get an exact answer to this because there are no choices.

Add 9x to both sides.

3y = 9x + 12              Divide by 3

3y/3 = 9x/3 + 12/3    Combine

y = 3x + 4

Now to get anything at all that is parallel to this and providing no answer because there is no intersection of the two lines, just change the 4 to something else. Here's one example

y = 3x + 8

As long as the number in front of the x's is the same, they are parallel with no point in common.

To solve the equation, distribute the 5 into the parentheses, combine like terms, and simplify to find that the solution for x is 0.

To solve the equation 5(2x \\- 3) = x \\- 15 + 9x for x, we start by distributing the 5 into the parentheses on the left side:

5(2x) - 5(3) = x - 15 + 9x

which simplifies to:

10x - 15 = x - 15 + 9x

Combine like terms by subtracting x from both sides:

10x - x - 15 = 9x - x - 15

Leaving us with:

9x - 15 = 8x - 15

Next, we can cancel the -15 on both sides, since they are equal and opposing, which simplifies the equation to:

9x = 8x

Subtract 8x from both sides to isolate x:

9x - 8x = 0

And we find that:

x = 0

Answer:

The volume of juice is 38.4 pi in^3

Step-by-step explanation:

First we need to find the volume of the cylinder

V = pi r^2 h

We need the radius

r = d/2 = 8/2 =4

V = pi * 4^2 *12

V = pi *16*12

V = 192 pi in^3

Remember we need the exact volume so we cannot approximate pi

Now it is 20% full of juice

Multiply the volume by 20 percent

192 pi * 20%

192 pi * .20

38.4 pi

The volume of juice is 38.4 pi in^3
