Answer:
Car B is travelling at the faster speed.
Step-by-step explanation:
Given that,
The distance covered by car A = 100 m
Time of car A, t = 5 s
The distance covered by car B = 100 m
Time of car B, t = 2 s
We need to find which one is travelling at the faster speed.
Speed = distance/time
For car A,
[tex]v_A=\dfrac{100\ m}{5\ s}\\\\v_A=20\ m/s[/tex]
For car B,
[tex]v_B=\dfrac{100\ m}{2\ s}\\\\v_B=50\ m/s[/tex]
So, car B is travelling at the faster speed.
A manufacturer determines that the cost of making a computer component is $4.171717. Write the repeating decimal cost as a fraction and as a mixed number.
Answer:
As Mixed Fraction
= $ (4 171717/1000000)
As a fraction
= $(4171717/1000000)
Step-by-step explanation:
A manufacturer determines that the cost of making a computer component is $4.171717. Write the repeating decimal cost as a fraction and as a mixed number
As a mixed fractions
= $4.171717 = $4 + 171717/1000000
= 4 171717/1000000
As. Fraction
= 4171717/1000000

How do I do this? Please give subtle explanation too. I don't really understand at all. If I understand this question, I'll understand the rest.
(it's 54 points too lol)
Step-by-step explanation:
An = -2 * An-1
What this means is that you multiply -2 to the term to get the next term.
Since our 1st term (A1) is -2, we have:
A2 = -2 * A1 = -2 * (-2) = 4,
A3 = -2 * A2 = -2 * (4) = -8,
A4 = -2 * A3 = -2 * (-8) = 16,
A5 = -2 * A4 = -2 * (16) = -32,
A6 = -2 * A5 = -2 * (-32) = 64.
Hence our first 6 terms in the GP are
-2, 4, -8, 16, -32 and 64.

Required
Select which is equivalent
(a): [tex]x-5> 4[/tex] and [tex]2x-10 >8[/tex]
Multiply both sides of [tex]x-5> 4[/tex] by 2
[tex]2 * (x - 5) > 4 *2[/tex]
[tex]2 * x - 2*5 > 4 *2[/tex]
[tex]2x - 10 > 8[/tex]

(b): [tex]x-5> 4[/tex] and [tex]2x+10 >8[/tex]
Multiply both sides of [tex]x-5> 4[/tex] by 2
[tex]2 * (x - 5) > 4 *2[/tex]
[tex]2 * x - 2*5 > 4 *2[/tex]
[tex]2x - 10 > 8[/tex]
Hence: [tex]x-5> 4[/tex] is not equivalent to [tex]2x+10 <8[/tex]
(c): [tex]x+5> 4[/tex] and [tex]2x+10 <8[/tex]
Multiply both sides of [tex]x+5> 4[/tex] by 2
[tex]2 * (x + 5) > 4 *2[/tex]

you multiply the 2 and 7 and then add the 4
Answer:
18
Step-by-step explanation:
what this wants you do do is use PEMDAS. the number in parentheses always means to multiply. first youre gonna multiply 2 by 7 which gives you fourteen. then add 4 to 14 which gives you 18.

A king owned land outside of his castle he has partitioned the land to give as gifts to his 5 sons what fraction of land did the king give to each of his sons here is zeke solution andy got 1/2 bill got 1/5 carl got 1/5 dirk got 1/8 and evan got 1/8 identify zeke's two errors correct them and explain why your answers are correct
Picture relating to the question is attached
Answer:
Andy = 1/2
Bill = 1/8
Carl = 1/8
Evan = 1/8
Dirk = 1/8
Step-by-step explanation:
According to the picture depicting the sharing of the land :
Fraction of the total rectangular plot = 1
Andy got a portion of the whole divided into 2 = 1/2
Fraction left after Andy's portion:
1 - 1/2 = 1/2
1/2 of the fraction left was divided equally between Dirk and Evan
Hence ;
1/2 of 1/2 = 1/2 * 1/2 = 1/4
Dirk's share = 1/4 ÷ 2 = 1/4 * 1/2 = 1/8
Evan's share = 1/4 ÷ 2 = 1/4 * 1/2 = 1/8
Fraction of land left :
1 - (1/2 + 1/8 + 1/8) = 1 - 3/4 = 1/4
1/4 was divided equally into 2 for Bill and Carl:
Bill's share = 1/4 ÷ 2 = 1/4 * 1/2 = 1/8
Carl's share = 1/4 ÷ 2 = 1/4 * 1/2 = 1/8
z=2 = 27

Need help with explicit rule. Please help.
Answer:
An = 74(1.07)^n-1
Step-by-step explanation:
Here, we want to get the explicit rule
We are told that the sequence is geometric
At hour 4, we have that this is the 4th term
With conformance to the rule of geometric progression;
T4 = ar^3
90 = ar^3
for the 6th hour, this is the sixth term
103 = ar^5
dividing the 6th term by the 4th term, we have that
103/90 = ar^5/ar^3
103/90 = r^2
r = 1.07
To get a, we simply use any of the terms to substitute
using;
ar^3 = 90
a = 90/r^3
a = 90/1.07^3
a = 73.5 which is approximately 74
So the explicit rule is as follows;
An = 74(1.07)^n-1

solve the rational equation: 7 - 2/x = 4 + 10/x
Answer:
7 - 2 / x = 4 + 10 / x
or , 7 - 4 = 10 / x + 2 / x
or , 3 = 12 / x
or , x = 12 / 3
Therefore , x = 4

Jason bought a soft drink for 2 dollars and 8 candy bars He spent a total of 26 dollars how much did each candy bar cost
Answer: Each candy bar cost him 3$
Step-by-step explanation:
First you subtract 26-2 to get 24. This is since he purchased the drink for 2$. Now he uses the 24 dollars to buy 8 candy bars, to figure how much each is you have to divide. You divide 24 by 8 in order to get 3.

The diagram shows a sector of a circle radius 10 cm.
Find the area of the sector, giving
your answer correct to 1 decimal place.
135°
10 cm
please give the working out aswell !!
Answer:
Area of sector = 117.6 cm²
Step-by-step explanation:
Radius of sector r = 10 cm
Angle Ф = 135°
We need to find Area of sector
The formula used is: [tex]\mathbf{Area\:of\:Sector=\frac{\theta}{360^{\circ}}\times \pi r^2}[/tex]
Where Ф is the angle, and r is the radius.
Putting values and finding area of sector
[tex]\mathbf{Area\:of\:Sector=\frac{\theta}{360^{\circ}}\times \pi r^2}\\Area\:of\:Sector=\frac{135}{360}\times 3.14 (10)^2\\Area\:of\:Sector=0.375 \times 3.14 \times 100\\Area\:of\:Sector=117.75[/tex]
Now, rounding off answer to 1 decimal place:
[tex]Area\:of\:Sector=117.6\: cm^2[/tex]
So, Area of sector = 117.6 cm²

Choose the correct way to end the sentence.
The line x-2y=4 and y=2x -2 are
A parallel
B neither
C perpendicular
Answer: B) neither
================================================
Let's isolate y in the first equation. This way we can find the slope.
x-2y = 4
-2y = 4-x
-2y = -x+4
y = (-x+4)/(-2)
y = -x/(-2) + 4/(-2)
y = (1/2)x - 2
This matches with y = mx+b form with m = 1/2 being the slope.
The slope of y = 2x-2 is m = 2
------------------------------
The slope of the first line is 1/2 and the slope of the second line is 2.
Since the two slopes (1/2 and 2) are not equal, this means the lines are not parallel.
Also, the two slopes do not multiply to -1, so the lines aren't perpendicular either.
This leads to B) neither as the final answer.

4xy = 88. If y = 2, then what is x?
Answer: x = 11
Step-by-step explanation:
first, i did simple calculations.
4x(2) = 88
that calculates out to:
8x = 88
then, i divided both sides by 8, in order to get x by itself.
8x/8 = 88/8
x = 11
