Answer:
B. It makes more sense to find an underestimate to make sure there are enough seats for everybody who buys a ticket to the show.
Step-by-step explanation:
Since in the question it is mentioned that there is 56 seats in an auditorium and 32 seats in each row
So this would create more sense to determine the underestimate as there is a sufficient seats for purchasing a tickets to the show
Therefore the option b is correct
Answer:
The answer is C.
Step-by-step explanation:
You need to overestimate to know the exact amount of tickets you need
The perimeter of a square field is 6400m. Find the cost of reaping the field at Rs.35 per 100 sq. m.
Answer:
side= 6400/4
=1600
therefore the area= 1600*1600
2560000
cost of reaping 100sq.m.=35
cost of reaping 1sq.m= 0.35
cost of reaping 2560000m sq= 2560000*0.35
= 906000
How do I solve this? 18= -1 over 2k
Answer:
-1/36
Step-by-step explanation:
18=-1/(2k)
2k=-1/18
k=(-1/18)/2
k=(-1/18)(1/2)
k=-1/36
What is the Domain of the relation below:
{(0, 1), (-2,5), (3, 2), (-1, 5), (3,-2)}
Write your answer from smallest to largest with a comma.
D = {........
Answer:
(-2, -1, 0, 3,3)
Step-by-step explanation:
The domain simply refers to the possible x-values the function can take
so by listing out all the x-values of the individual points, we have all the domains
That will be ;
(-2, -1, 0, 3,3)

L.H.S of 2x - 3 = 8 is
Answer:
5.5
Step-by-step explanation:
2x -3 = 8
then
2x = 8 + 3 = 11
means
2x = 11
then
x = 11 ÷ 2
x = 5.5
___________________
we change the sign (- or +)
then take the number to the other side of the equal (with the changed sign)
leaving the x alone so that we can answer the equation..
_____________
to make sure

Answer:
5/3-4>=21
Step-by-step explanation:
This is because it says no less than 21, meaning it says it does not want a number to be less than 21 but 21 is included.
White an equation in point slope form of the line that passes through the given point and with the given slope m
(-5,1), m=6
Answer:
y=6x+31
Step-by-step explanation:
Answer:
[tex]y-1=6(x+5)[/tex]
Step-by-step explanation:
The given point is (-5, 1) and the slope is 6.
Point-slope form is given by:
[tex]y-y_1=m(x-x_1)[/tex]
We will let (-5, 1) be (x₁, y₁) and we will substitute 6 for m. Therefore:
[tex]y-(1)=6(x-(-5))[/tex]
Simplify:
[tex]y-1=6(x+5)[/tex]

How do you solve 2x=10
Hello!!
So when we have 2x = 10 we are looking for what x equals. This means you'll want to eliminate what you can to get your answer. What you do on one side must be done on the other. Let's give that a go, sha'll we?
2x = 10
We need to use the inverse operation to eliminate a factor. Since 2x is 2 times x we'll have to divide it.
2x/2 = 10
2 divided by 2 cancels each other out and leaves us with the following;
x = 10
So, x = 10
I hope I helped!!

Prove whether the quadrilateral is a parallelogram using the Distance & Slope Formulas D(-5, -6), E(5, 2), F(4, -4), G(-6, -12)
Answer:
See the distances bellow
Step-by-step explanation:
Given data
D(-5, -6), E(5, 2)
substitute into the expression for the distance
[tex]d= \sqrt((x_2 - x_1)^2 + (y_2 - y_1)^2)\\\\d= \sqrt((5+5)^2 + (2+6)^2)\\\\d= \sqrt((10)^2 + (8)^2)\\\\d= \sqrt(100 +64)\\\\d= \sqrt((164)\\\\d= 12.80[/tex]
E(5, 2), F(4, -4)
[tex]d= \sqrt((x_2 - x_1)^2 + (y_2 - y_1)^2)\\\\d= \sqrt((4-5)^2 + (-4-2)^2)\\\\d= \sqrt((-1)^2 + (-6)^2)\\\\d= \sqrt(1+36)\\\\d= \sqrt((37)\\\\d= 6.08[/tex]
F(4, -4), G(-6, -12)
[tex]d= \sqrt((x_2 - x_1)^2 + (y_2 - y_1)^2)\\\\d= \sqrt((-6-4)^2 + (-12+4)^2)\\\\d= \sqrt((-10)^2 + (-8)^2)\\\\d= \sqrt(100+64)\\\\d= \sqrt((164)\\\\d= 12.80[/tex]
G(-6, -12), D(-5, -6)
[tex]d= \sqrt((x_2 - x_1)^2 + (y_2 - y_1)^2)\\\\d= \sqrt((-6+5)^2 + (-12+6)^2)\\\\d= \sqrt((-1)^2 + (-6)^2)\\\\d= \sqrt(1+36)\\\\d= \sqrt((37)\\\\d= 6.08[/tex]

A certain hydraulic system operates at 6,000 PSI. Complete the percentage change in the volume of oil in the system as the pressure is increased from zero to 6,000 PSI if the oil has a Bulk Modulus of 186,000 PSI.
Answer:
the percentage change in the volume of the oil is -3.22%
Step-by-step explanation:
The computation of the percentage change in the volume of the oil is given below:
= -(6,000 - 0) ÷ (186,000)
= -3.22%
This negative sign represents the decrease in the volume
Hence, the percentage change in the volume of the oil is -3.22%

On a scale drawing,1 in represents 8 feet. What is the actual length of a room that measures 3.4 inches
Answer:
27.2 ft
Step-by-step explanation:
Since 1 in on the drawing = 8 ft, we should find out how much ft is 3.4 in.
So, to get from 1 to 8, we multiply by 8.
And since we multiply by 8, we also have to do it to the other part as well.
So we would do:
8 x 3.4 = 27.2
Hope this helps! :)

Brainlist pls!
help ASAP PLEASE i need to get a 100
Answer:
Alternate Interior ∠s: 3 & 5, 4 & 6.
Corresponding ∠s: 1 & 5, 2 & 6, 3 & 8, 4 & 7.
Alternate Exterior ∠s: 1 & 8, 2 & 7.
Consecutive ∠s: 3 & 6, 4 & 5.
Step-by-step explanation:
Alternate interior angles must both be in between the parallel lines, it is almost like you are flipping the angle over the line, then moving it down, if that makes any sense.
Corresponding angles correspond, which means that they are the same (of course), but it is like you go directly down to the similar angle. You can visually see that angles are the same, an example is 1 & 5.
Alternate exterior angles are similar to alternate exterior angles, but they must be on the exterior of the parallel lines. Once again, it is like you are flipping the angle of the line, then turning it downwards, if it makes any sense that way to you.
Consecutive angles are always in between the two parallel lines on the same side. They add up to 180. So 4 & 5 is a good example.
Good luck.
What is the component form of the vector represented by 2a when a⃗ =〈−2,3〉?
2a = <__,___>
Answer:
[tex]\vec v = 2\cdot \vec a = \langle -4,6 \rangle[/tex]
Step-by-step explanation:
Let [tex]\vec a = \langle -2, 3 \rangle[/tex], we need to determine [tex]\vec v = 2\cdot \vec a[/tex], which can be found by applying the following property:
[tex]\alpha \cdot \langle x,y \rangle = \langle \alpha \cdot x, \alpha \cdot y\rangle[/tex], [tex]\forall \,\alpha,x,y\in \mathbb{R}[/tex] (1)
Then,
[tex]\vec v = 2\cdot \langle -2,3 \rangle[/tex]
[tex]\vec v = \langle -4,6 \rangle[/tex]
