Answer:Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the
10
. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

I need help with this and also the explanation plz
Answer:
The correct answer is 0 or A
Step-by-step explanation:
2/0+2 + 1/5 = 6/0+5
2/2 + 1/5 = 6/5
1 + 1/5 = 6/5
5/5 + 1/5 = 6/5
6/5 = 6/5
A skydiver jumps from a plane 10,000 feet above ground level. The height of the skydiver above the ground, in feet, can be modeled using the polynomial −32t2+10,000 in the absence of friction. Use the interactive below to calculate the average velocity over various intervals and to make observations about the relationship between average velocity and instantaneous velocity.
Answer:
Step-by-step explanation:

A room is thrice as long as the breadth. It contains 270m^3 of air and the cost of painting its four walls at Rs 15 per m^2 is Rs. 3600, find the cost of carpeting the floor at Rs. 98 per m^2.
Answer: ₹2646
Step-by-step explanation:
Given
The volume of the room is [tex]V=270\ m^3[/tex]
cost of painting the walls is ₹[tex]3600[/tex] at the rate of [tex]15\ m^2[/tex]
So, the area of walls is
[tex]\Rightarrow A=\dfrac{3600}{15}\\\\\Rightarrow A=240\ m^2[/tex]
This the area of 4 walls i.e.
[tex]\Rightarrow 240=2[hl+hb]\\\Rightarrow 120=h[l+b]\\\Rightarrow 120=4bh\quad [\text{length is thrice of width}]\\\Rightarrow 30=bh\qua \ldots(i)[/tex]
The volume of the room is given by
[tex]V=l\times b\times h\\270=3b\times b\times h\\90=hb^2\quad \ldots(ii)[/tex]
Divide (i) and (ii)
[tex]\Rightarrow \dfrac{90}{30}=\dfrac{b^2h}{bh}\\\\\Rightarrow b=3\ m[/tex]
So, the length of the room is
[tex]l=3b\\l=3\times 3\\l=9\ m[/tex]
The area of the floor is
[tex]\Rightarrow A_o=l\times b\\\Rightarrow A_o=9\times 3\\\Rightarrow A_o=27\ m^2[/tex]
The cost of flooring is
[tex]\Rightarrow 27\times 98\\\Rightarrow Rs.2646[/tex]

Sweet onions are on sale for $0.79 per pound. If an onion weighs 8 oz, how much does it cost to buy 5 onions?
Answer:
a pound is 16 oz. so 2 onions are a pound. meaning 5 onions equal 2 1/2 pounds.
2.5 × 0.79 = $1.975 (about $1.98)

Complete the square to find the vertex of this parabola. x2-16y-4x-12=0
Answer:
Step-by-step explanation:
x^2-16y-4x-12=0
Transpose and separate x and y
16y = x^2-4x-12
16y = (x^2-4x+4) -16
16y = (x-2)^2 -16
y = (1/16)(x-2)^2 -1
This means that the vertex is at
(x-2)=0 or x=2
y = -1
=> vertex (2,-1)

Drag the green point on the tape diagram to model a discount of 27%.
If the discount is 27%, then what percent of the original price do you pay?
Answer:
73%
Step-by-step explanation:
Let us have the original price as $100
A discount of 27% will be;
27/100 * 100 = $27
so, the value to be paid will be $100 - $27 = $73
Now, what percentage of $100 is the $73 that was paid
that would be;
73/100 * 100% = 73%
this is area right???
Answer:
Yes
Step-by-step explanation:
So permiter is two*lengths plus 2*width of a shape.
Area is the length times the width.
For examplel if a square has a length of 2, and a width of 3 the permiteter is:
2*2+3*3=
4+9
=
13
On the other hand, area would be:
2*3
=
6

Please help!!!
f(a) = 0 and f(b) = 0
3. If a frame usually sells for $13, and is on clearance for 55% off:
a. How much is the discount?
b. What is the final price of the frame?
Answer:
discount is -7.15
final price is $5.68
Step-by-step explanation:
55% of 13 = 7.15
subtract 7.15 from 13
It's an angles question. I keep getting 14 degrees. How do you do it?
Answer:
32
Step-by-step explanation:
By linear pair and exterior angle theorem:
[tex]x \degree + (180 - 99) \degree = 113 \degree \\ \\ x \degree + 81 \degree = 113 \degree \\ \\ x \degree = 113 \degree - 81 \degree \\ \\ x \degree = 32 \degree \\ \\ x = 32[/tex]
Help plz..And No links!! I repeat No links!!
Answer:
10^2 = 100
100 x 3.14 = 314(area of circle)
314 x 2 = 628(area of both two circles/base and top)
2 x 3.14 x 10 = 62.8(circumference),
62.8 x 6(height) = 376.8
Add areas:
376.8 + 628 = 1,004.8 m2 is your answer.
Use the distributive property to writer an equivalent expression 4(7u + 4w - 8)
Answer:
28u+16w-32
Step-by-step explanation:
Distributive property means you multiply everything on the inside of the parentheses by everything on the outside so....
4(7u)=28u
4(4w)=16w
4(-8)=-32

Increased dumping of sewage into a river caused an increase in parasites that attacked the local fish population. Turtles and birds that live in the same community eat the fish. What would happen between the turtles and birds if the fish population decreased by 50% as a result of the parasitism? *
A increased commensalism
B increased competition
C increased mutualism
D increased predation
Answer: The answer you are looking for is “B increased competition”
Step-by-step explanation: The reason why it is the answer b is when two species eat the same type of food and that said food is decreased as much as 50% there will be a lot of competition that will take place because both species want to survive so it is pretty much anyone for themselves.

Find the area of the combined rectangles. Please help me
Answer:
8: 190 yd , 9: 30 m, 10: 92 ft
Step-by-step explanation:
for 8, you can spit it up pretty simply. find 10x18 which is 180 and then 5x2 which is 10 so 8 is 190.
for 9, 2x8=18 for the top portion and for the sides 3x2=6, so twelve. Combined its 30m.
for 10, 10x8=80, then 6x2=12. so 92 ft combined.

Answer:
[tex]5\sqrt{3}[/tex]
Step-by-step explanation:
A triangle with angles of 30-60-90 will always have sides that measure in the following proportions:
The side opposite the 30* angle = a
The side opposite the 60* angle = [tex]a\sqrt{3}[/tex]
The side opposite the 90* angle = 2a
(I used "a" here because your question uses "x" and I don't want to confuse things, but usually people use "x" rather than "a")
They gave us that the hypotenuse (the side opposite the 90* angle) is 10, from there we can figure out the other sides:
Since the side opposite 90* is 2a, and 2a = 10, divide 10 by 2 and you get a = 5.
Once we know what "a" is, we can fill in the rest:
30* = 5
60* = [tex]5\sqrt{3}[/tex]
90* = 10

Answer:
a) The table of values represents the ordered pairs formed by the elements of the sequence ([tex]a_{i}[/tex]) (range) and their respective indexes ([tex]i[/tex]) (domain):
[tex]i[/tex] [tex]a_{i}[/tex]
1 6
2 11
3 16
4 21
5 26
b) The algebraic expression for the general term of the sequence is [tex]a(i) = 6 + 5\cdot (i - 1)[/tex].
c) The 25th term in the sequence is 126.
Step-by-step explanation:
a) Make a table of values for the sequence 6, 11, 16, 21, 26, ...
The table of values represents the ordered pairs formed by the elements of the sequence ([tex]a_{i}[/tex]) (range) and their respective indexes ([tex]i[/tex]) (domain):
[tex]i[/tex] [tex]a_{i}[/tex]
1 6
2 11
3 16
4 21
5 26
b) Based on the table of values, we notice a constant difference between two consecutive elements of the sequence, a characteristic of arithmetic series, whose form is:
[tex]a(i) = a_{1} + r\cdot (i - 1)[/tex] (1)
Where:
[tex]a_{1}[/tex] - First element of the sequence.
[tex]r[/tex] - Arithmetic difference.
[tex]i[/tex] - Index.
If we know that [tex]a_{1} = 6[/tex] and [tex]r = 5[/tex], then the algebraic expression for the general term of the sequence is:
[tex]a(i) = 6 + 5\cdot (i - 1)[/tex]
c) If we know that [tex]a(i) = 6 + 5\cdot (i - 1)[/tex] and [tex]i = 25[/tex], then the 25th term in the sequence is:
[tex]a(25) = 6 + 5\cdot (25 - 1)[/tex]
[tex]a(25) = 126[/tex]
The 25th term in the sequence is 126.
