You could express 48+32 by doing 50 + 30 because your adding 2 to the 48 and subtracting 2 from the 32 so that’s not how you could express that.

You could express it by using negatives.

-1(-48-32)

-1(-80)

80

The orginal was:

48+32

=80

The answer is 90 elves.

Here's how to find it

100 giants = 100/160 or 5/8

3/8 is left for the elves

The second option:

[tex]Volumen_{max}=(8-2x)(6-2x)*x[/tex]

From the statement, we know the dimensions of the box, and the length of the sides to be cut (x).

So,

Working with the length of the box:

Let be 8 the length of the cardboard for the length of the box, so, if we cut out the side of length "x", we have:

[tex]Length=(8-(x+x))=(8-2x)[/tex]

Now,

Working with the width of the box:

Let be 6 the length of the cardboard for the width of the box, so, if we cut out the side of length "x", we have:

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

Now that we already know the length and the width of the box, we must remember that the bottom of the box will have the same length "x", so, the greatest possible volume of the cardboard box will be:

[tex]Volumen_{max}=Length*Width*Bottom=(8-2x)(6-2x)*x[/tex]

Given : f(x) = 5x² - 7(4x + 3)

Now,

f(3) = 5 × 3² - 7(4 × 3 + 3)

= 5 × 9 - 7(12 + 3)

= 45 - 7 × 15

= 45 - 105

= - 60

Hence,

f(3) = - 60

To find f(3) for the function f(x) = 5x² - 7(4x + 3), we substitute 3 into the function and simplify to get f(3) = -60.

To evaluate f(3) for the function f(x) = 5x² - 7(4x + 3), we need to substitute the value of 3 into the function:

f(3) = 5(3)² - 7(4(3) + 3)

Now we simplify the expression step by step:

The final result is:

f(3) = 45 - 105 = -60.

The answer is 22.5

Step-by-step explanation:

Ava and Kelly will be 3/4 mile apart after 22.5 minutes of running at their respective speeds of 6 mph for Ava and 8 mph for Kelly.

To determine when Ava and Kelly will be 3/4 mile apart in a road race, we must calculate the difference in distance they cover over the same time frame. Ava runs at 6 miles per hour (mph) and Kelly runs at 8 miles per hour (mph). The difference in their speeds is 2 mph (8 mph - 6 mph).

We need to calculate the time it takes for this difference in speed to result in a gap of 3/4 miles. Since speed is distance divided by time, we can use the formula:
Time = Distance / Speed. Substituting the values we have, we get:
Time = (3/4) miles / 2 mph. When we calculate this, we find the time to be 3/8 hours, or 22.5 minutes.

Therefore, Ava and Kelly will be 3/4 mile apart after 22.5 minutes of running at their respective average speeds.

Answer: [tex]1.38\frac{g}{cm^3}[/tex]

Step-by-step explanation:

You need to remember the formula for calculate the density:

[tex]density=\frac{mass}{volume}[/tex]

In this case:

[tex]density_{(rock)}=\frac{mass_{(rock)}}{Volume_{(rock)}}[/tex]

You know that:

[tex]mass_{(rock)}=15.5g[/tex]

And when it is placed in a graduated cylinder, the volume is displaced from 25.0 mL to 36.2 mL.

Then, the volume of the rock is:

[tex]Volume_{(rock)}=36.2mL-25.0mL=11.2mL[/tex]

Since [tex]1mL=1cm^3[/tex], you can rewrite the volume as:

[tex]Volume_{(rock)}=11.2cm^3[/tex]

Substituting values into the formula, you get that the density of the rock is:

[tex]density_{(rock)}=\frac{15.5g}{11.2cm^3}=1.38\frac{g}{cm^3}[/tex]

Final answer:

The vertex form of the quadratic equation  [tex]y = -x^2 - 10x - 21[/tex]is  [tex]y = -(x + 5)^2 + 4[/tex], with the vertex being (-5, 4).

Explanation:

To find the vertex form of the quadratic equation  [tex]y = -x^2 - 10x - 21[/tex], we need to complete the square. Here's a step-by-step guide:

Start with the given quadratic equation:  [tex]y = -x^2 - 10x - 21.[/tex]

Factor out the coefficient of the  [tex]x^2[/tex]term from the first two terms:  [tex]y = -(x^2 + 10x) - 21.[/tex]

Find the number that completes the square for the expression [tex]x^2 + 10x.[/tex]This is  [tex](10/2)^2 = 25.[/tex]

Add and subtract this number inside the parentheses, then group the perfect square and the constant terms: y = -[tex](x^2 + 10x + 25 - 25) - 21.[/tex]

Rewrite the equation, recognizing the perfect square trinomial:  [tex]y = -[(x + 5)^2 - 25] - 21.[/tex]

Combine the constant terms: [tex]y = -(x + 5)^2 + 4.[/tex]

The vertex form of the equation is  [tex]y = -(x + 5)^2 + 4[/tex], where the vertex of the parabola is (-5, 4).

Answer:

The equation of the line is y = 4x

Step-by-step explanation:

* Lets revise how to form an equation of a line from its slope and

 a point on the line

- The equation of a line is written as y = mx + b where m is the

  slope of the line and b is the y-intercept.

- The line intersect the y-axis at point (0 , b)

* Lets solve the problem

- The line has slope = 4

- The line passes through the point (2 , 8)

∵ The slope = 4

∵ m is the slope of the line in the equation

∴ m = 4

- Substitute the value of m in the equation

∵ y = mx + b

∴ y = 4x + b

- To find the value of b substitute the x-coordinate and the

  y-coordinate of the point instead of x and y of the equation

∵ The point (2 , 8) lies on the line

∵ y = 4x + b

- Put x = 2 and y = 8 in the equation to find b

∴ 8 = 4(2) + b ⇒ simplify

∴ 8 = 8 + b ⇒ subtract 8 from both sides

∴ 0 = b

- That means the y-intercept = 0 and the line passing through

  the origin point

∴ y = 4x + 0

* The equation of the line is y = 4x

Answer:

Final answer is [tex]F\left(1\right)=0.2625[/tex].

Step-by-step explanation:

Given function is [tex]F\left(t\right)=\frac{2.1}{2^3t}[/tex].

Now we need to use that function [tex]F\left(t\right)=\frac{2.1}{2^3t}[/tex] to find the value of F(1).

F(1) means value of functino F(t) at t=1, So plug t=1 into given function.

[tex]F\left(t\right)=\frac{2.1}{2^3t}[/tex]

[tex]F\left(1\right)=\frac{2.1}{2^3(1)}[/tex]

[tex]F\left(1\right)=\frac{2.1}{8(1)}[/tex]

[tex]F\left(1\right)=\frac{2.1}{8}[/tex]

[tex]F\left(1\right)=0.2625[/tex]

Hence final answer is [tex]F\left(1\right)=0.2625[/tex].

Answer:

The solution is [tex]F(1) = \frac{1}{4}[/tex]

Step-by-step explanation:

Given function is [tex]2\times \frac{1}{2^{3t}}[/tex]

We need to find the value of function [tex]F(t) = 2\times \frac{1}{2^{3t}}[/tex] at t = 1

Replace t with 1 in [tex]F(t) = 2\times \frac{1}{2^{3t}}[/tex]

[tex]F(1) = 2\times \frac{1}{2^{3(1)}}[/tex]

[tex]F(1) = 2\times \frac{1}{2^{3}}[/tex]

[tex]F(1) = 2\times \frac{1}{8}[/tex]

[tex]F(1) = \frac{2}{8}[/tex]

[tex]F(1) = \frac{1}{4}[/tex]

Therefore, the solution is [tex]F(1) = \frac{1}{4}[/tex]

Step-by-step explanation:

This graph shows two vertical asymptotes, one at x = +3, the other at x = 4.  Thus, we omit the first two answer choices.  Next, we substitute 0 for x and determine the y value in Answer Choice C:  F(0) = 0.  Does the graph go through (0, 0)?  Yes, it does.  Next, evaluate F at x = 3.5 (halfway between x =  3 and x = 4); that is, evaluate function D at x = 3.5.  Does the y value come out to be -4 as shown in the graph?  Yes, it does.    So D is the correct function to match this graph.

Considering the vertical asymptotes of the function, and it's behavior, it is found that the rational function graphed below is given by:

D. [tex]f(x) = \frac{1}{(x - 3)(x - 4)}[/tex]

The vertical asymptotes are the values of x which are outside the domain, which in a fraction are the zeroes of the denominator.

Henry started with 20 convertibles and 5 trucks.

His aunt bought him x miniature trucks.

Now, his convertibles represent 1/5 of his collection.  How many trucks did her aunt buy?

So, if his convertible represent 1/5 of his collection now, that means his collection is 5 times larger than the number of convertibles.  We know he has 20 convertibles... so the collection now counts 100 (5 * 20) items.

Out of 100 items, we remove the 20 convertibles to get a total of 80 trucks.

Then we subtract the initial 5 trucks... so, his aunt bought him 75 trucks.

Order of Operations in Mathematics follow this following rule :

This rule is known as the PEMDAS method.

In working on a mathematical problem, we first calculate operation that is in parentheses, follow by exponentiation, then multiplication or division, and finally addition or subtraction.

Let us tackle the problem!

Let :

Number of Additional Miniature Trucks from Henry's Aunt = X

Initial Number of Convertibles = 20

Initial Number of Trucks = 5

Henry's aunt bought him some more miniature trucks,Henry found that one-fifth of his collection consisted of convertible.

[tex]\frac{1}{5}( 20 + 5 + x ) = 20[/tex]

[tex]\frac{1}{5}( 25 + x ) = 20[/tex]

[tex]( 25 + x ) = 20 \div \frac{1}{5}[/tex]

[tex]25 + x = 20 \times \frac{5}{1}[/tex]

[tex]25 + x = \frac{20 \times 5}{1}[/tex]

[tex]25 + x = \frac{100}{1}[/tex]
