Step-by-step explanation:
Given:
1/(10×10×10)
Find:
The equivalent representations among the options ...
10^-3, 0.01, 0.001, 10^3
Solution:
The denominator is 10×10×10 = 1000, so the fraction is 1/1000.
The decimal representation of that is 0.001. In exponential form, it is ...
1/10^3 = 10^-3
Equivalents among the offered choices are 10^-3 and 0.001.

A. -6
B. -0.7
C.0.4
D.3
Answers
The value of "a" for a narrow graph will be equal to 7.
What is a graph?A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.
GIven functions are:-
f(x) = ax²
f(x) = 7
At the value of a=7 the graph of function f(x) = 7x² opens upward and is narrower than the graph of f(x) = x².
Hence the value of "a" for a narrow graph will be equal to 7.

Which of the equations are true identities? A. N ( n − 2 ) ( n + 2 ) = n 3 − 4 n B. ( x + 1 ) 2 − 2 x + y 2 = x 2 + y 2 + 1
Answers
Answer:
Both A and B are true identities
Step-by-step explanation:
A. N ( n − 2 ) ( n + 2 ) = n 3 − 4 n
We need to show that (left-hand-side)L.H.S = R.H.S (right-hand-side)
So,
n ( n − 2 ) ( n + 2 ) = n(n² - 2²) (difference of two squares)
= n³ - 2²n (expanding the brackets)
= n³ - 4n (simplifying)
So, L.H.S = R.H.S
B. ( x + 1 )² − 2x + y² = x² + y² + 1
We need to show that (left-hand-side)L.H.S = R.H.S (right-hand-side)
So,
( x + 1 )² − 2x + y² = x² + 2x + 1 - 2x + y² (expanding the brackets)
= x² + 2x - 2x + 1 + y² (collecting like terms)
= x² + 1 + y²
= x² + y² + 1 (re-arranging)
So, L.H.S = R.H.S
So, both A and B are true identities since we have been able to show that L.H.S = R.H.S in both situations.

XY bisects ∠AXB. If m∠AXB = -18x° and m∠AXY = (3x2 - 12)°. Find m∠BXY. Please help, I'm blanking!!!
Answers
Answer:
m<BXY = 36degrees
Step-by-step explanation:
If XY bisects ∠AXB, then;
<AXY + <BXY = <AXB
Given
m∠AXY = (3x^2 - 12)°
m∠AXB = -18x°
Required
Find m∠BXY.
From the formula above;
Find m∠BXY = <AXB - <AXY
m<BXY = -18x - (3x^2-12)
m<BXY = -18x - 3x^2 + 12
m<BXY = -3x^2 -18x + 12
Also <AXY = m<BXY
3x^2 - 12 = -3x^2 -18x + 12
6x^2 + 18x -24 = 0
x^2+3x-4 = 0
Factorize
x = -3±√9+16/2
x = -3±5/2
x = -3+5/2 and -3-5/2
x = 2/2 and -8/2
x = 1 and -4
Substitute x = 1 into m<BXY
m<BXY = -3x^2 -18x + 12
m<BXY = -3(1)^2 -18(1) + 12
m<BXY = -3 -18+ 12
m<BXY = -9
when x= -4
m<BXY = -3(-4)^2 -18(-4) + 12
m<BXY = -3(16) +72+ 12
m<BXY = -48+84
m<BXY = 36degrees

How many plastic cubes can fit into the box?
20 plastic cubes
45 plastic cubes
125 plastic cubes
160 plastic cubes
Answers
Answer:
160 plastic cubes
Step-by-step explanation:
first find the volume the box can hold so,
4 x 2.5 x 2 = 20ft^3
from their find the volume of each plastic cube so,
.5 x .5 x .5 = .125ft^3
then you can divide the volume of the box by the volume of the plastic cube to see how many will fit
20 ÷ 0.125 = 160 plastic cubes

Answer:
fraction to decimal calculator to find what's an equivalent decimal for the fractional number 48/400.
0.12 is a decimal and 12/100 or 12% is the percentage for 48/400.
Step-by-step explanation:
A fraction consists of two numbers and a fraction bar:
48/400
The number above the bar is the numerator: 48
The number below the bar is the denominator: 400
Divide the numerator by the denominator to get fraction's value:
Val = 48 ÷ 400
Introduction. Percent, p%
'Percent (%)' means 'out of one hundred':
p% = p 'out of one hundred',
p% = p/100 = p ÷ 100.
Calculate fraction's value.
Divide the numerator by the denominator to get fraction's value:
48/400 =
48 ÷ 400 =
0.12
Note:
100/100 = 100 ÷ 100 = 100% = 1
Multiply a number by the fraction 100/100,
... and its value doesn't change.
Calculate the percent value:
0.12 =
0.12 × 100/100 =
(0.12 × 100)/100 =
12/100 =
12%;
