Answer:
= 32
Step-by-step explanation:
= 8 [ 20 - { (9-5) }² ]
= 8 [ 20 - { (4) }² ]
= 8 [ 20 - 16 ]
= 8 [ 4 ]
= 32

How many (5in. by 5in. by 5in) cubes will occupy a classroom 9ft by 8ft by 7ft in dimension?
Answer:
Step-by-step explanation:
first convert feet to inches because the measure of cubes is in inches
( 12 inches=1 foot)
9 ft = 12*9=108 inches
8 ft=12*8=96 inches
7 ft= 12*7=84
the volume of the one cube= 5*5*5=125
volume of the classroom: 108*96*84=870912
divide : 870912/125=6967 cubes

12 percent of 4000 is what
Answer:
480
Step-by-step explanation:
4000 * 0.12 = 480
Answer:
the answer is 480
Step-by-step explanation:
Write 12% as
12
100
Since, finding the fraction of a number is same as multiplying the fraction with the number, we have
12/100 of 4000
12/100 × 4000
find 5 rational numbers between 1/3 & 2/5
Answer:
41/120, 7/20, 43/120, 11/30, 3/8
Step-by-step explanation:
Write the numbers.
1/3 & 2/5
We need a common denominator, but not the least common denominator. Both 3 and 5 are factors of 60, so let's use 60 as the common denominator.
Multiply 1/3 by 20/20:
1/3 = 20/60
Multiply 2/5 by 12/12:
2/5 = 24/60
Let's multiply each fraction again, but this time by 2/2.
1/3 = 40/120
2/5 = 48/120
Now it's easy to find 5 numbers between 40 and 48, so we get:
41/120, 42/120, 43/120, 44/120, 45/120
Some of these fractions can be reduced, so our answer is:
41/120, 7/20, 43/120, 11/30, 3/8
Hudson bought a plant and planted it in a pot near a window in his house. The initial height of the plant was 8 inches and it grew at a rate of 3 inches per month. Write an equation for H,H, in terms of t,t, representing the height, in inches, of the plant tt months after Hudson bought the plant.
Answer:
H = 3t + 8
Step-by-step explanation:
Since the plant has an initial height of 8 inches, this will be added to the amount it grows each month.
3t will represent how much it grows t months after he bought the plant, since it grows 3 inches each month.
So, the equation will be H = 3t + 8

1. Find the equation of the tangent line to the parabola y = x^3 at the point P(2,8).
Use x = 2.1, 2.01, 2.001, 2.0001, 2.00001; 1.9,1.99, 1.999,1.9999, 1.99999 to find slope.
Answer:
a) Equation of the tangent of the parabola
12 x - y -16=0
b)
slope of the tangent at x=2.1
[tex](\frac{dy}{dx}) = 3(2.1)^{2} = 13.23[/tex]
slope of the tangent at x=2.01
[tex](\frac{dy}{dx}) = 3(2.01)^{2} = 12.1203[/tex]
Step-by-step explanation:
Step(i):-
Given parabola y = x³ ....(i)
Differentiating equation (i) with respective to 'x'
[tex]\frac{dy}{dx} = 3x^{2}[/tex]
slope of the tangent
[tex](\frac{dy}{dx})_{(2,8)} = 3x^{2} = 3(2)^{2} =12[/tex]
Step(ii):-
Equation of the tangent of the parabola
[tex]y-y_{1} = m (x-x_{1} )[/tex]
y-8 = 12 (x -2)
12 x - 24 -y +8 =0
12 x - y -16=0
b)
slope of the tangent at x=2.1
[tex](\frac{dy}{dx}) = 3(2.1)^{2} = 13.23[/tex]
slope of the tangent at x=2.01
[tex](\frac{dy}{dx}) = 3(2.01)^{2} = 12.1203[/tex]
Find the coordinates of the other endpoint of the segment, given its midpoint and one endpoint. (Hint: Let (x,y) be the unknown endpoint. Apply the midpoint formula, and solve the two equations for x and y.) midpoint (-4,13) endpoint-(0,5)
Answer:
end point of a segment X₂ = - 8 ; Y₂ = 21
Step-by-step explanation:
given;
midpoint = ( Mx = -4 , My = 13 )
endpoint ₁ = ( X₁ = 0 , Y₁ = 5 )
find the other endpoint ₂ ( X₂ , Y₂)
use the mid point formula to get the other endpoint:
Mx = ( X₁ + X₂ ) / 2 My = ( Y₁ + Y₂ ) / 2
- 4 = (0 + X₂) / 2 13 = (5 + Y₂) / 2
-8 = 0 + X₂ 26 = 5 + Y₂
X₂ = -8 Y₂ = 21

Answer:
Step-by-step explanation:
On a field trip, the school bus drove five more than twice as many miles in the afternoon as in the morning. If the whole trip was 125 miles, how many miles did the bus travel in the morning and how many in the afternoon?
Answer:
morning - 40
afternoon - 85
Step-by-step explanation:
The bus traveled 40 miles in the morning and 85 miles in the afternoon.
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
The school bus traveled five miles more on a field trip in the afternoon than it did in the morning. If the journey was 125 kilometers long
Let x the distance traveled by bus in the morning.
As per the given condition, we can get the equation shown below:
⇒ x + 2x + 5 = 125
⇒ 3x + 5 = 125
⇒ 3x = 120
⇒ x = 40
In the afternoon, the bus traveled 2x + 5 miles.
Now substitute the value of x in the equation for the afternoon miles to include:
⇒ 2 × 40 +5 = 85
Therefore, the bus traveled 40 miles in the morning and 85 miles in the afternoon.

Which sequence of transformations creates a similar, but not congruent, triangle? (4 points) 1) Rotation and translation 2) Reflection and rotation 3) Dilation and rotation 4) Translation and reflection
Answer:
3) Dilation and rotation

Rotation, translation, and reflection are rigid motions. They always result in congruent figures. If you don't want a congruent figure, you need to have dilation by a factor other than 1.

For the following system, if you isolated x in the first equation to use the substitution method, what expression would you substitute into the second equation? −x + 2y = −6 3x + y = 8
Answer:
[tex]x=2y+6[/tex]
Step-by-step explanation:
So we have the system:
[tex]-x+2y=-6\\3x+y=8[/tex]
If we isolate the x-variable in the first equation:
[tex]-x+2y=-6[/tex]
Subtract 2y from both sides:
[tex]-x=-6-2y[/tex]
Divide both sides by -1:
[tex]x=2y+6[/tex]
Therefore, we would substitute the above into the second equation:
[tex]3x+y=8\\3(2y+6)+y=8[/tex]
The answer is 2y+6
Further notes:
To solve for the system, distribute:
[tex]6y+18+y=8[/tex]
Simplify:
[tex]7y+18=8[/tex]
Subtract:
[tex]7y=-10[/tex]
Divide:
[tex]y=-10/7\approx-1.4286[/tex]
Now, substitute this value back into the isolated equation:
[tex]x=2(-10/7)+6\\x=-20/7+42/7\\x=22/7\approx3.1429[/tex]
Step-by-step explanation:
Start by solving the equation for x (☓)
[tex] - x + 2y = 6 \\ \: \: \: \: \: 3 + y = 8[/tex]
[tex]x = 6 + 2y[/tex]
Substitute the given value of x for the equation 3 + y = 8[tex]3(6 + 2y) + y = 8[/tex]
solve the equation for y[tex]y = - \frac{10}{7} [/tex]
substitute the given value of y into the equation x = 6 + 2[tex]x = 6 + 2 \times ( - \frac{10}{7} )[/tex]
solve the equation for x[tex]x = \frac{22}{7} [/tex]
The possible solution of the system is the ordered pair (x,y)[tex] (\frac{22}{7} . - \frac{10}{7} )[/tex]
The dot (.) in the center is supposed to be a comma but the scientific keyboard does not support a comma[tex](x.y) \: \: ( \frac{22}{7} . - \frac{10}{7} )[/tex]

What combination of transformations is shown below?
A) translation, then rotation
B) translation, then reflection
C) rotation, then reflection
D) rotation, then translation
Explanation:
Going from figure (1) to figure (2) has us rotate 90 degrees counterclockwise. Note the smallest side of the green figure how it is horizontal, and it corresponds to the smallest side of the blue figure and it is vertical. The center of rotation is the top right corner of the green figure.
Then we apply a translation to go from figure (2) to figure (3). This is another way of saying we shifted the figure some distance left/right and up/down. In this case, we shifted 1 unit to the right and 4 units down.

For what values of a and b does a - b = b - a?
how can a+b=0?
is a+b=0 a single word followed by the question mark ? the sentence is not complete if “a+b=0” is the subject, it’s like: how can cat?
is the sentence rather: how can a+b be equal to 0 ( meaning zero) ? in that case, supposing we are talking of the usual sum of two elements of an additive group : how can the sum of a and b, written a+b, can be equal to zero, then this seems more like a question about what powers do have any two elements of a group to, by association through addition, to obtain a zero value. Like “how can my brother and me get one of these chocolates ?”

Now, in your question, maybe a and b are not any two elements of said group but elements well identified before,
suppose you know a is 1 and b is -1 for instance. Then how can 1–1=0? is a very good question : it marvels at the fact that the addition does what it is supposed to do. Lots of things don’t, and lots of people take it for granted that things do what they are supposed to de, like speeds add up, etc.
let’s suppose for example, a is 1 and b is 2.
Then your question is very justified : how can 1+2 be equal to 0 ? it’s a scandal, either the computer is broken, or my mind is , and if anywhere in the world 1+2 =0, there is something wrong with the world.
