a kilobyte is 2^10 bytes and a megabyte is 2^20 . how many kilobytes are in a megabyte
Answer:
1024
Step-by-step explanation:
so first you would do 2^10 and 2^20
2^10 = 1024
2^20 = 1048576
then you would just divide 1048576 by 1024
1048576 / 1024 = 1024

Which equation represents a linear function?
x = 3
y = 16
y = -3x + 10
y = 3x2 + 1
Please help me!!
Answer:
y = 16 and y = -3x + 10Step-by-step explanation:
The equation of a linear function:
y = mx + b
m - slope
b - y-intercept
x = 3 - it's a vertical line. It's not equation of a linear function
y = 16 - it's a horizontal line. It's an equation of a linear function
where m = 0, b = 16
y = -3x + 10 - it's an equation of a linear function
where m = -3, b = 10
y = 3x² + 1 - it's a quadratic function ( x² ).
Answer:
y = 16 and y = -3x + 10

Bill's school is selling tickets to a spring musical. On the first day of ticket sales the school sold
10 senior citizen tickets and 8 child tickets for a total of $170. The school took in $185 on the
second day by selling 10 senior citizen tickets and 11 child tickets. Find the price of a senior
citizen ticket and the price of a child ticket.
A) senior citizen ticket: $13, child ticket: $5 B) senior citizen ticket: $12, child ticket: $7
C) senior citizen ticket: $5, child ticket: $13 D) senior citizen ticket: $21, child ticket: $6
Answer:
A
Step-by-step explanation:
If you play around with each of the answers, you'll find that 13*10=130 (where $13 is the cost of each of 10 senior tickets) plus 5*8=40 (where $5 is the cost of each of 8 child tickets) equals $170.
Hope this helps!! <3
The price of a senior citizen and child ticket is required.
The correct option is A) senior citizen ticket: $13, child ticket: $5

[tex]\boxed{\sf Option \ 4}[/tex]
Step-by-step explanation:
[tex]\sqrt{2x-3} +x=3[/tex]
Subtract x from both sides.
[tex]\sqrt{2x-3} +x-x=-x+3[/tex]
[tex]\sqrt{2x-3}=-x+3[/tex]
Square both sides.
[tex]( \sqrt{2x-3})^2 =(-x+3)^2[/tex]
[tex]2x-3=x^2-6x+9[/tex]
Subtract x²-6x+9 from both sides.
[tex]2x-3-(x^2-6x+9 )=x^2-6x+9-(x^2-6x+9)[/tex]
[tex]-x^2 +8x-12=0[/tex]
Factor left side of the equation.
[tex](-x+2)(x-6)=0[/tex]
Set factors equal to 0.
[tex]-x+2=0\\-x=-2\\x=2[/tex]
[tex]x-6=0\\x=6[/tex]
Check if the solutions are extraneous or not.
Plug x as 2.
[tex]\sqrt{2(2)-3} +2=3\\ \sqrt{4-3} +2=3\\\sqrt{1} +2=3\\3=3[/tex]
x = 2 works in the equation.
Plug x as 6.
[tex]\sqrt{2(6)-3} +6=3\\ \sqrt{12-3} +6=3\\\sqrt{9} +6=3\\3+6=3\\9=3[/tex]
x = 6 does not work in the equation.
Answer:
option d
Step-by-step explanation:
[tex]\sqrt{2x-3}+x = 3\\\\\sqrt{2x-3} = 3 -x\\[/tex]
Square both sides
[tex](\sqrt{2x-3})^{2}=(3-x)^{2}\\\\\\2x-3=9-6x+x^{2}\\\\0=x^{2}-6x + 9 - 2x + 3\\[/tex] {Add like terms}
[tex]x^{2} - 8x + 12 = 0[/tex]
Sum = -8
Product = 12
Factors = -2 , - 6
x² - 2x - 6x + (-2) * (-6) = 0
x(x -2) - 6(x -2) = 0
(x -2) (x - 6) = 0
x - 2 =0 ; x - 6 = 0
x = 2 ; x = 6
roots of the equation : 2 , 6
But when we put x = 6, it doesn't satisfies the equation.
When x = 6,
[tex]\sqrt{2x-3} + x = 3\\\\\sqrt{2*6-3}+6 = 3\\\\\sqrt{12-3}+6=3\\\\\sqrt{9}+6=3\\\\[/tex]
3 + 6≠ 3
Therefore, x = 2 but x = 6 is extraneous

Question in screenshot answer must be in cm
Answer:
30.5 cm
Step-by-step explanation:
0 < h ≤ 10 ⇔ Midpoint = 5
10 < h ≤ 20 ⇔ Midpoint = 15
20 < h ≤ 30 ⇔ Midpoint = 25
30 < h ≤ 40 ⇔ Midpoint = 35
40 < h ≤ 50 ⇔ Midpoint = 45
50 < h ≤ 60 ⇔ Midpoint = 55
⇒ Multiply each corresponding midpoint with it's frequency
(5 × 1) + (15 × 4) + (25 × 7) + (35 × 2) + (45 × 3) + (55 × 3) = 610
⇒ Divide the total of 610 by the frequencies added together
610 ÷ (1 + 4 + 7 + 2 + 3 + 3) = 610 ÷ 20 = 30.5

Answer:
72 inch²
Step-by-step explanation:
Rectangular classroom
Length=36ft
Width=32ft
scale drawing length = 9 inches
Scale drawing width=x
Ratio of the length to the scale drawing length = 36/9
Ratio of the width to the scale drawing width=32/x
To find x
36/9=32/x
Cross product
36x=32*9
x=288/36
=8
x=8
Area of a rectangle= length × width
Length=9 inches
Width=8 inches
Area of the rectangular classroom= 9 inches × 8 inches

try this answer good luck
Answer:
Answer: 1/2
Step-by-step explanation:
Given : Figure B is a scaled copy of Figure A.
We know that the scale factor is the ratio of the corresponding sides of two similar figures.
From , the graph we assume that that one point = one unit of length.
Then, the dimension of one side of figure A = 4 units and the dimension of corresponding side of Figure B = 2.
Then, the scale factor is given by:
k = 2/4 = 1/2
Hence, the scale factor is 1/2

The standard deviation of the data set is 1.6
What is Standard Deviation?
The standard deviation is a measure of the amount of variation or dispersion of a set of values.
Here, given data

6 2 12 4 8
8 3 24 0 0

11 1 11 9 9
mean = ∑xf / ∑f
= (12+24+9+11)/(2+3+1+1)
= 56 / 7
mean = 8
Variance = ∑fd²/∑f
= 18 / 7
= 2.57
Standard Deviation = √variance

Answer:

Step-by-step explanation:
Given
A Shaped Frame of two congruent sides
Required
Determine the angle made with the ground
Given that there are two congruent sides, this implies that the A frame is an isosceles triangle;
Let the two angles made with the ground be represented by x
Angles in a triangle when added equals 180;
Hence;
[tex]x + x + 34 = 180[/tex]
[tex]2x + 34 = 180[/tex]
Subtract 34 from both sides
[tex]2x + 34 - 34 = 180 - 34[/tex]
[tex]2x = 180 - 34[/tex]
[tex]2x = 146[/tex]
Divide both sides by 2
[tex]\frac{2x}{2} = \frac{146}{2}[/tex]
[tex]x = \frac{146}{2}[/tex]
[tex]x = 73[/tex]
Hence, the angle with the ground is 73 degrees

What is the 52nd term of the sequence below?
-38, -35, -32, -29...
Answer:
115
Step-by-step explanation:
It adds 3 every time and starts with -38. Our equation is:
a52 = -38+3(52-1);
a52 = -38 + 153
a52 = 115
Answer:
115
Step-by-step explanation:
→ First we need to work out the nth term. First we find the difference between each term
-38, -35, -32, -29... ⇔ +3
→ We know the first bit is 3n now we have to find the other section. We need to write the 3 times tables on top of each corresponding term
3 , 6 , 9 , 12
-38, -35, -32, -29...
→ We can see the to get from 3 to -38 we minus 41. So the nth term is
3n - 41
→ Now we substitute in 52 for n
3 × 52 - 41
→ Simplify

If we have [tex](a+b)^2[/tex] we can calculate this as:
[tex](a+b)*(a+b)[/tex]
So, applying distribution property, we get:
[tex](a+b)*(a+b)=a*a+a*b+b*a+b*b[/tex]

[tex]b*b=b^2[/tex]

Answer: C. 71,224,900
Based on the power, move the decimal point that many spaces to the right. (e.g., If it's 7.9 × 10^3, then move the decimal three spaces to the right, and you'd get 7900.)
3.14159 × 10^7 = 31415900
9.897752 × 10^6 = 9897752
2.468 × 10^7 = 24680000

And c + 112 = 180
So -112 is c = 68

length of a rectangle is 3 times its width.If its perimeter is 24 centimetres what is the area of the rectangle?
Answer:
27 cm²Step-by-step explanation:
The length is 3 × width.
l = 3w
The perimeter is 24 centimeters.
P = 2l + 2w
24 = 2(3w) + 2w
24 = 6w + 2w
24 = 8w
3 = w
The width is 3 centimeters.
l = 3(3)
l = 9
The length is 9 centimeters.
Area is l × w.
A = l × w
A = 9 × 3
A = 27
The area is 27 squared centimeters.
Answer:
27
Width= x
Length= x × 3 =3x
so, 3x+3x+x+x=24
8x=24
x=24/8
x=3
so, length=3(3)=9
width=3
therefore,
Area=9×3
