Answer:
6 km
Step-by-step explanation:
1 meter = 1/1000 km
(1 meter = 1/1000 km) x 1000
1000 meters = 1 km
6000 meters = ?
1 x 6000m = 1000 x ?
6000 = 1000 x 6
6000/1000 = 1000 x 6/1000
6 = 6
Both sides divided by 1000 are 6, so the answer is 6 km.

A novelty store sells 8 comic books for every 3 action figures. On
Monday, they sold 32 comic books. On Tuesday, they sold 18 action
figures. What is the difference between the number of action
figures sold on Monday and Tuesday? Explain.
Answer:
Step-by-step explanation:
THE answer is 6
First Calculate the number of action figures sold on Monday:
8 comic books for every 3 action figures
32 comic books =? action figures
8 x 4 = 32
so, 3 x 4 = 12 action figures sold on Monday
next Find the difference between the number of action figures sold on Monday and Tuesday
They're asking for the difference, so you subtract
18 - 12 = 6
Hence, the difference in the number of books on Monday and Tuesday is 6

Write the number that represents the English words: five hundred thirteen millionths
Answer:
513,000,000
Step-by-step explanation:
To write five hundred thirteen million in numbers change “five hundred thirteen million” to “513”, then multiply 513 by 106.
Alternatively, move the decimal point 6 places to the left:
513 × 106 = 513000000,
513 → 5,130 → 51,300 → 513,000 → 5,130,000 → 51,300,000 → 513,000,000.
Besides, five hundred thirteen million means:

Answer:
12kg
Step-by-step explanation:

A charm bracelet costs $65, plus $25 for each charm. The equation -25x+y=65 represents the cost y (in dollars) of the bracelet, where x is the number of charms.
a. Graph the equation.
b. How much does a bracelet with three charms cost?
Answer:
a. see attached
b. $140
Step-by-step explanation:
a.The graph starts at y=65 when x=0 and increases by 25 for each increase of 1 in x. The attachment shows a graph of the equation.
__
b.Use x=3 in the equation.
-25x +y = 65
y = 65 +25x = 65 +25(3) = 140
A bracelet with 3 charms costs $140.

-3,2 and 8,2 in slope intercept form
Answer:
y = 2
Step-by-step explanation:
So we need to find the slope first.
m = y_2 - y_1/x_2 - x_1
Substitute
m = 2 - (2)/8 - (-3)
Simplify now.
Multiply -1 by 2
m = 2 - 2/(8 - (-3)
2 from 2
m = 0/8 - (-3)
Now we need to simplify the denominator.
To do so lets multiply -1 by -3
m = 0/8 + 3
m = 0/11
m = 0
Now we have the slope of 0 and the given point of (-3, 2)
So y - (2) = 0 * (x - (-3)) (Formula > y - y_1 = m(x - x_1) this comes from the original slope equation]
Simplify further
y - 2 = 0 * (x + 3)
Now we solve for y
Multiply 0 by x + 3
y - 2 = 0
Add 2 to both sides
y = 2

○ 60cm^2
Answer:
C. 52.5cm^2
Step-by-step explanation:
Area of a triangle - A=1/2bh or area=1/2 base times height
Area of a rectangle - A=lw or area=length times width
Separate the shapes first, you would draw a line between the two if this was on paper.
Find the separate areas.
Rectangle area:
8*5=40
Triangle area:
find the height first. the height of this triangle is the same as the length of the rectangle minus the 1 and 2 cms.
8-1-2=5
1/2*5*5=12.5
Now add the areas:

Answer:
C
Step-by-step explanation:
609/504 = 1.208333333
58/48 = 1.208333333
They are proportional since they divide to the same number.
An object is launched directly upward from ground level at a rate of 96 feet per second. The height of the object is given by the equation y = −16x^2 + 96x.
When is the object AT OR ABOVE a height of 128 feet?
A) 1 ≤ x ≤ 3
B) 1 ≤ x ≤ 4
C) 2 ≤ x ≤ 3
D) 2 ≤ x ≤ 4
Answer:
D
Step-by-step explanation:
The x in the spot (x,y) is the time, while the y is how high the object is at.
The length of the time when the object is at or above 128 feet starts at exactly 2 seconds and ends at exactly 4 seconds.
A rectangular field is ten times as long as it is wide. If the perimeter of the field is 1540 feet, what are the dimensions of the field?
Answer:
700 by 70
Step-by-step explanation:
The equation for perimeter is 2(l + w). Since the length has an assigned value, l will become 10w.
2(10w + w) = 1540
First, add the parenthetical expression to get 11w.
2(11w) = 1540
Now, DISTRIBUTE! 2(11w) becomes 22w.
22w = 1540
Lastly, divide by 22 to get 70. You can also say that this could be 22w = 154 * 10. 22 * 7 is 154 (140 + 14), and 7 * 10 is 70.
w = 70
Now that we know the width, substitute 70 for w in the 10w expression.
l = 10(70)
Just multiply and you'll get 700.
l = 700
Now we know the dimensions to be 700 * 70 (or 70 * 700; I just prefer to put the length first)

Suppose you have invested $1500 at an APR of 8%. Use the Rule of 72 to estimate how long it will be until your investment reaches $3000.
Answer:
25 Years. thank you for your question
The time required for the investment of $1500 reaches $3000 with APR of 8% using the rule of 72 is 9 years.
What is the Rule of 72?The rule of 72 is the easy way to calculate the number of years required the investment with the given interest rate. It can be calculated as,
[tex]t\approx\dfrac{72}{r}[/tex]
Here, (t) is the time period and (r) is the rate of return.
The invested amount is $1500 and the value of APR is 8%. The time we have to calculate using the rule of 72.
The final amount of the investment is $3000 which is double the initial amount. Thus, the time period required to double the investment with 8% of interest is,
[tex]t\approx\dfrac{72}{8}\\t\approx9[/tex]
Thus, the time required for the investment of $1500 reaches $3000 with APR of 8% using the rule of 72 is 9 years.

Answer:
a) y = 10x +500
b) $500
c) $15 for 100; $10.50 for 1000
Step-by-step explanation:
a)We assume the given "cost per unit" is the variable cost per unit. The total cost (y) for x units, given some fixed cost (b), is ...
y = 10x +b
For 100 units, this is ...
1500 = 10(100) +b
500 = b . . . . . . . . subtract 1000
The cost function rule is ...
y = 10x +500
__
b)The fixed cost is the cost of producing 0 units:
y = 10(0) +500
y = 500 . . . . . . . the fixed cost in dollars
__
c)The average cost (ac) of producing n units is the total cost divided by n:
ac(n) = (10n +500)/n = 10 +500/n
The average cost for 100 units is
ac(100) = 10 +500/100 = 15 . . . average dollar cost for 100 units
The average cost for 1000 units is ...
ac(1000) = 10 +500/1000 = 10.50 . . . average dollar cost for 1000 units
