How do we express one-half of the difference of a number cubed and one?

Answer:

100 + 40 + 40 + 40 + 40

Step-by-step explanation:

area of base = 10 x 10 = 100 square units

area of each triangular side = 0.5 x 10 x 8 = 40 square units.

Total area = 1 base + 4 sides

= 100 + 40 + 40 + 40 + 40

Wow the wording of these questions keeps getting more like a version of clue than a school exam or test. Goodluck!

The largest number that should be added to -11 to obtain a sum less than -5 is 5.

To find the largest number that should be added to –11 to get a sum less than –5 you need to relate these two numbers. If you add a number to -11 that brings you exactly to -5, it means you're adding 6 (because -11 + 6 = -5). However, you need the sum to be less than -5. So the largest number you can add to -11 to get a number less than -5 would be 5 (because -11 + 5 = -6, and -6 is less than -5). So, the answer is 5.

Answer: 50 meters

Step-by-step explanation: I just finished the pretest

Answer:  The ball is 50 m off the ground after 2 seconds

Step-by-step explanation:

Given the function relating the height of an object off the ground to the time spent falling is a quadratic relationship.

Therefore if h=height and t=time then

[tex]h=a+bt+ct^{2}[/tex]       ----------(A)

where a,b and c are constants

Apply given conditions

At t=0s h=90 m

=> 90 m = a+0+0

=>a=90 m

Also the ball has been just dropped at t=0 s

=>[tex]\frac{\partial h}{\partial t}=0=>\frac{\partial (a+bt+ct^{2})}{\partial t}=0[/tex]

=>[tex]b+2ct=0[/tex]

For t=0s b = 0

Thus equation (A) is reduced to [tex]h=90+ct^{2}[/tex]

At  t= 3 s , h=0 m

[tex]\therefore 0= 90 +9c=>c=-10 \frac{m}{s^{2}}[/tex]

Finally we get [tex]h=90-10t^{2}[/tex]

Therefore at t= 2.0 s , [tex]h=(90-10\times 2^{2})m=50 m[/tex]

Thus the ball is 50 m off the ground after 2 seconds

I am glad to help.

Answer:

The answer is D. y = x2 + 6x + 7

x + y = 1

Step-by-step explanation:

Answer: OPTION A.

Step-by-step explanation:

Given the equation [tex]\frac{c-1}{x}+d=cd[/tex], you need to solve for the variable "x":

Subtract "d" from both sides of the equation:

[tex]\frac{c-1}{x}+d-d=cd-d\\\\\frac{c-1}{x}=cd-d[/tex]

Multiply both sides of the equation by "x":

[tex](\frac{c-1}{x})x=x(cd-d)\\\\c-1=x(cd-d)[/tex]

Divide both sides of the equation by [tex](cd-d)[/tex]:

[tex]\frac{c-1}{cd-d}=\frac{x(cd-d)}{cd-d}\\\\\frac{c-1}{cd-d}=x[/tex]

Factor out "d" in the denominator and simplify. Therefore:

[tex]\frac{(c-1)}{d(c-1)}=x\\\\x=\frac{1}{d}[/tex]

The correct solution for the equation c-1/x+d=cd is x = -1/(cd - c - d). Unfortunately, none of the provided options, 1/d, d, or c/d match this solution.

To solve the equation c-1/x+d=cd, we first move the terms involving x to one side and the constant to the other side. So the equation becomes:

-1/x = cd - c - d.

We then take reciprocals on both sides (since we do not want x in the denominator) to get:

x = -1/ (cd - c - d). Thus, the solution of the given equation is x = -1/(cd - c - d).

Unfortunately, none of the options A) 1/d, B) d, or C) c/d match the obtained solution.

[tex]x+y=20\\\underline{x-y=40}\\2x=60\\x=30\\\\30+y=20\\y=-10[/tex]

-10 and 30

Answer:

The numbers are 30 and -10.

Step-by-step explanation:

The sum of two numbers is 20 (addition)

x + y = 20

The difference is 40 (subtraction)

x - y = 40

To solve an equation, you can only have one variable. Solve one of these for a variable (it doesn't matter which one).

x - y = 40   Add y to both sides

x = 40 + y

Now you have a new value for x (40 + y), so you can plug it into your other equation.

x + y = 20   Plug in (40 + y) for x

40 + y + y = 20   Combine like terms (y + y)

40 + 2y = 20   Subtract 40 from both sides

2y = -20   Divide both sides by 2

y = -10

Now, plug your y into either equation.

x + y = 20   Plug in -10 for y

x + (-10) = 20   Simplify

x - 10 = 20   Add 10 to both sides

x = 30

Check your work by plugging these numbers into both equations.

x + y = 20   Plug in

30 + (-10) = 20   Simplify

30 - 10 = 20   Simplify

20 = 20

and

x - y = 40   Plug in

30 - (-10) = 40   Simplify

30 + 10 = 40

40 = 40

Answer:

The elapsed time is 7hrs and 1 minute.

The elapsed time from 5 in the afternoon to 1 minute after midnight is 7 hours and 1 minute, taking into consideration the division of a day into a.m. and p.m.

The key to solving this question is first understanding how we measure time in day and night, which are demarcated by a.m. and p.m.. Each cycle of 24 hours is divided into two parts: 12 hours from midnight to noon (a.m.) and another 12 hours from noon to midnight (p.m.).

Let's calculate the elapsed time from 5 in the afternoon to 1 minute past midnight. From 5 p.m to midnight, there are 7 hours. Adding the 1 minute past midnight, the total elapsed time is 7 hours and 1 minute.

Answer:

V≈2.53×105^5

Step-by-step explanation:

Base edge:  54

Height:  260

Formula to find volume is: V=a^2h /3

Hope this helps!

For this case we have that by definition, the volume of a square base pyramid is given by:

[tex]V = \frac {1} {3} * L ^ 2 * h[/tex]

Where:

L: It's the side of the square base

h: It's the height of the pyramid

According to the data we have:

[tex]L = 54\m\\h = 260\m[/tex]

Substituting in the formula:

[tex]V = \frac {1} {3} * (54) ^ 2 * 260\\V = \frac {1} {3} * 2916 * 260\\V = \frac {1} {3} * (758160)\\V = 252,720 \ m ^ 3[/tex]

Thus, the volume of the building is [tex]252,720 \ m ^ 3[/tex]

Answer:

[tex]252,720 \ m ^ 3[/tex]

y - y1 = m(x - x1) is the general point slope form

y - 3 = 5(x - 4) plug in the given values

y - 3 = 5x - 20

y = 5x - 20 + 3

y = 5x - 17

The answer in slope intercept form is y = 5x-17

If you want to convert to standard form, then

y = 5x - 17

y+17 = 5x

17 = 5x - y

5x - y = 17 which is the answer in standard form (Ax + By = C)

[tex]\large\boxed{y=\dfrac{1}{4}x+3}[/tex]

Step-by-step explanation:

The slope-intercept form of an equation of a line:

[tex]y=mx+b[/tex]

m - slope

b - y-intercept → (0, b)

From the graph we have the points (4, 4) and (0, 3) → b = 3.

We have the equation:

[tex]y=mx+3[/tex]

The formula of a slope:

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

Put the coordinates of the points:

[tex]m=\dfrac{3-4}{0-4}=\dfrac{-1}{-4}=\dfrac{1}{4}[/tex]

Finally we have:

So putting x+h in place of x

[tex]f(x+h)= \frac{x+h}{1+(x+h)}\\=\frac{x+h}{1+x+h}[/tex]

Points P and Q are not the same due to their different positions in the division of the directed segment. Point P is closer to A while Point Q is closer to B.

Point P and Q are not the same point. In the directed segment from A to B, Point P divides the segment in a way that the ratio of AP to PB is 1:3, meaning Point P is closer to A. On the contrary, Point Q divides the segment from B to A in a way that the ratio of QB to QA is 1:3, implying that Point Q is closer to B. Therefore, P and Q have different positions on the segment.

https://brainly.com/question/30277001

#SPJ12

No, Point P and Q are not the same. P is closer to A because it partitions the directed segment from A to B, whereas Q is closer to B as it partitions the segment from B to A, taking into account the directionality of the segments.

In mathematics, partitioning points on a directed segment refers to dividing the segment into distinct parts according to a given ratio. Point P partitions the directed segment from A to B into a 1:3 ratio, which means P is one part from A and three parts from B. On the other hand, Point Q partitions the directed segment from B to A into a 1:3 ratio, indicating that Q is one part from B and three parts from A.

Given this, P and Q are not the same point. P is closer to point A and Q is closer to point B since the directionality of the segment is taken into account. The direction from A to B is not the same as the direction from B to A, so the points P and Q that partition these segments in a 1:3 ratio will end up at different locations.

Answer:

(D) 30pi inches

Step-by-step explanation:

First, we use the given volume, the given height, and the formula of the volume of a cylinder to find the radius of the base. Then we use the radius of the base to find the circumference of the base.

[tex] volume = \pi r^2 h [/tex]

[tex] volume = 6750 \pi~in.^3 [/tex]

We set the formula equal to the volume and replace h with 30 in.

[tex] \pi r^2 h = 6750 \pi~in.^3 [/tex]

[tex] \pi r^2 \times 30 ~in. = 6750 \pi~in.^3 [/tex]

Divide both sides by 30pi in.

[tex] r^2 = 225 ~in.^2 [/tex]

Take the square root of each side.

[tex] \sqrt{r^2} = \sqrt{225 ~in.^2} [/tex]

[tex] r = 15~in. [/tex]

The radius of the base is 15 in.

Now we use the radius of the base and the formula of the circumference of a circle to find the answer.

[tex] circumference = 2 \pi r [/tex]

[tex] circumference = 2 \pi \times 15~in. [/tex]

[tex] circumference = 30 \pi ~in. [/tex]
