Answer:

2.5 meters per second

Step-by-step explanation:

Given,

The speed of Charlotte = 9 km/h

That is, the distance covered in 1 hour = 9 km,

∵ 1 km = 1000 m

So, the distance covered in 1 hour = 9000 m,

∵ 1 hour = 60 minutes and 1 minute = 60 seconds,

⇒ 1 hours = 3600 seconds,

∴ The distance covered in 3600 seconds = 9000 m,

⇒ Distance covered in 1 second = \frac{9000}{3600} = 2.5 m,

Hence, his/her speed = 2.5 meters per second

Margie is packing 108 small boxes into a large carton. the small boxes will fill all of the space inside the large carton. Each
just olya [345]
2 inches wide
that means that the height of the large carton is 2 inches

find the volume of the carton
V=108 times volume of small box
V=108 times 1 times 2 time s3
V=648 in^2

height is 2
V=LWH
648=LW2    (note, this is not LW^2 but 2 times LW)
divie both sides by 2
324=LW
legnth of base is less than 36
div
we just need to find the values of legnth and width such that LW=324 and L<36 and that L or W is divisible by 3 (since each box is 3 inches long)

so lets factor 324
324=2*2*3*3*3*3
group them and find possible values for legnth and width less than 36 and divsible by 3
possible values

(L,W,H) possible values are
(27,12,2)
(18,18,2)

Craig has $1850 dollars in a bank account that he uses to make automatic payments of $400.73 on his car loan. If Craig stops mak
Ivenika [448]

Given:

Amount in the bank account = $1850

Monthly payment of can loan = $400.73

To find:

When would automatic payments make the value of the account zero?

Solution:

Craig stops making deposits to that account. So, amount $1850 in the bank account is used to make monthly payment of can loan.

On dividing the amount by monthly payment, we get

\dfrac{1850}{400.73}=4.61657

It means, the amount is sufficient for 4 payment but for the 5th payment the amount is not sufficient.

Therefore, the 5th automatic payments make the value of the account zero.

Which equation represents a line that passes through (5, 1) and has a slope of StartFraction one-half EndFraction?
saul85 [17]

Answer:

y – 1 = y minus 1 equals StartFraction one-half EndFraction left-parenthesis x minus 5 right-parenthesis.(x –5)

Step-by-step explanation:

we know that

The equation of the line into point slope form is equal to

y-y1=m(x-x1)

we have

m=\frac{1}{2}

(5,1)

substitute

y-1=\frac{1}{2}(x-5)

The function f(x)=-x^2-2x+15 is shown on the graph. What are the domain and range of the function?
adoni [48]

Answer:

Domain is all real numbers

y ≤ 16

Step-by-step explanation:

The domain is the set of x values that the graph covers. There is no restriction on the x values. The domain is all real numbers.

The range is the set of y values that the graph covers. The highest the y values go is 16 at the top of the parabola. So the range is y ≤ 16.
