Answer:
900,000
Step-by-step explanation:
rounding is quite simple, the number 927,545, like all numbers, has different number places/values. the number 9 is in the 100,000th place and to round you look at the number in the place to the right of it which is 2. the number 2 is is less than 5 so it can't raise the number 9 to a ten. because of this, it reduces all of the other numbers to 0. leaving you with the number 900,000

Answer:
B c² = h² + b² -2bx +x²
Step-by-step explanation:
The square of the binomial can be expanded using the distributive property:
c² = h² +(b -x)²
c² = h² +(b -x)(b -x)
c² = h² +b(b -x) -x(b -x)
c² = h² +b² -xb -bx +x²
c² = h² +b² -2bx +x² . . . . . matches choice B

You need to tile 17 kitchen floors in a new apartment building each floor needs 309 tiles how many tiles will you need for all the floors
And explain
Answer:
You will need 5,253 tiles.
Step-by-step explanation:
17 kitchen floors x 309 tiles for each floor = 5,253 tiles total
Answer:
The answer is 5253
Step-by-step explanation:
We will use the unitary method
Make two columns one for kitchen floors and one for tiles
In the first row you will put 1 kitchen floor and 309 tiles
In the second row you will put 17 kitchen floors and x tiles
Then crossmultiply and 17x309 is equal to 5253

List the domain and range of the relation {(1, -9), (8,8), (0, -9), (8, 1), (1,9)}
Answer:
D={1, 8,0}
R={-9, 8,1,9}
Step-by-step explanation:
Here,
we, know, domain(D) =set of all first elements
thus, D={1,8,0}
again, range(R) =set of all second elements
thus R={-9,8,1,9}
The perimeter of the triangle below is 4x + 3y. Find the measure of the missing side.
Answer:
let side be t
t + x + y +x + y = 4x + 3y
t + 2x + 2y = 4x + 3y
t = 2x +y
so missing side length is 2x + y

3/8 of a scholarship fund was 1500 find the full amount of the scholarship fund
Answer:
The full scholarship fund will be 4000
Step-by-step explanation:
When doing these types of problems I like to do this.
1500 ÷ 3 = 500 (We do this because you want to find out what 1/8 is)
Since 500 is 1/8 of the part, all you have to do is multiply 500 by 8
500 × 8 = 4000

find the zeroes for P(x)=6x³-13x²+x+2 given 0.5 is one of the zeroes
The answers :
-1/3 , 0.5 , 2
Step-by-step explanation:
that means the expression is the result of a multiplication with (x-0.5) being one factor.
so, we divide the whole expression by this and then deal with the remaining quadratic equation.
6x³ - 13x² + x + 2 / x - 0.5 = 6x² - 10x - 4
- 6x³ - 3x²
----------------------------
- 10x² + x + 2
- - 10x² + 5x
----------------------------
- 4x + 2
- - 4x + 2
----------------------------
finished. 0
so, the whole expression is also
P(x) = (x-0.5)×(6x² - 10x - 4)
now we need to find the 2 zero points of the quadratic part.
the general solution to a quadratic equation is
x = (-b ± sqrt(b² - 4ac))/(2a)
a = 6
b = -10
c = -4
x = (10 ± sqrt(100 - 4×6×-4))/12 =
= (10 ± sqrt(100 + 96))/12 = (10 ± sqrt(196))/12 =
= (10 ± 14)/12
x1 = (10+14)/12 = 24/12 = 2
x2 = (10-14)/12 = -4/12 = -1/3

HELP PLS IM BEGGING YOU PLS HELP, its due todayyy pls. Angle CBD is the only one i got right and the rest is wrong. I dont know how to answer it anymore.
Answer:
try It would be number 81
Step-by-step explanation:
Abc= 110
ceo=70
dbe=110 or 120
and abe= 60 70 or 81
Answer:
ABC=112 degrees
DBE=112 degrees
ABE=68 degrees
Step-by-step explanation:
CBD=ABE
ABE=68 degrees
First let's take these as X,
ABC=DBE=X(Vertically opposite angles)
ABC+DBE+CBD+ABE=360(angles around a point)
x + x +68 +68 =360
2x +136 =360
2x =360-136
2x = 224
x =112 degrees
therefore;
ABC=112 degrees
DBE=112 degrees
is a graph with asymptotes discontinious?
Answer:
In order for the function to be discontinuous at an asymptote, the curve needs to exist on both sides of the asymptote. If the curve only exists on one side of the asymptote, then there's no discontinuity at that point.

test the validity of the following whenever he participates in a race, he is the winner. either he participates in the race or he is sick he is not the winner. therefore he is sick
To test the validity of a given argument, we need to see if we can find a counter-example that makes one of the statements non-valid. If after analyzing the statements we can't find a counterargument, then we can conclude that the argument is valid.
Here we will find that the argument is valid.
We can write this as:
If he participates in a race then he is the winner.
Either he participates in the race, or he is sick.
He is not the winner, then, he is sick.
Now, from the first statement, we know that always that this person participates in a race, he wins.
From the second statement we know that he only participates if he is not sick, we can rewrite that one as:
"If he is sick, then he does not participate in the race".
Finally, from the third one, if he does not win, then he is sick.
This makes sense, he only does not participate when he is sick, then the only races where he is not the winner, are these races where he does not participate, and he does not participate only if he is sick, then this is a valid argument.
Concluding, the 3 statements are valid, as we can't find any counterargument to any of these 3.

The graph of the invertible function h is shown on the grid below.
What is the value of h^-1 (-1)?
Answer:
1
Step-by-step explanation:
[tex]h {}^{ - 1} ( - 1)[/tex]
means that what is the value of the inverse function of h(x) when x=-1. The inverse function x and y values swap with original functions. When x=1, y=-1 so the inverse of that will be when x=-1, y=1.
Applying the inverse function concept, it is found that [tex]h^{-1}(-1) = 1[/tex]
The inverse function [tex]f^{-1}(x) = a[/tex] means that [tex]f(a) = x[/tex].
In this problem, it is asked [tex]h^{-1}(-1)[/tex].
From the graph, it is taken that at the original function, when [tex]x = 1, y = -1[/tex], hence [tex]h(1) = -1[/tex].Then, applying the inverse function, we have that [tex]h^{-1}(-1) = 1[/tex], and thus 1 is the value of the inverse function.A similar problem, also involving inverse functions, is given at https://brainly.com/question/23950969

Answer:
[tex]-3(t+1)(8t-3)[/tex]
Step-by-step explanation:
First, factor both the denominators completely:
[tex]9-24t\\= 3(3-8t)\\= 3(-8t+3)\\= -3(8t-3)[/tex]
[tex]8t^2+5t-3\\= 8t^2+8t-3t-3\\= 8t(t+1)-3(t+1)\\= (8t-3)(t+1)[/tex]
Now, we can see that the factors of the first denominator are -3 and 8t-3.
The factors of the second denominator are t+1 and 8t-3.
To find the LCD, multiply all of these factors together:
[tex]-3(t+1)(8t-3)[/tex]
Notice how we only multiply 8t-3 in the equation once. This is because it was present in both denominators, unlike the other factors.
I hope this helps!

Find the denominators' Least Common Multiple (LCM)
First five multiples of 5: 5, 10, 15, 20, 25
First five multiples of 4: 4, 8, 12, 16, 20
Since [20] is the first term that appears in both multiples, it would be the LCM of 4 and 5
Convert the fractions to common denominator
2/5 = (2 × 4) / (5 × 4) = 8 / 20
1/4 = (1 × 5) / (4 × 5) = 5 / 20
Simplify by subtraction
