Answer:

C 5 km

Step-by-step explanation:

so, 5 cm on the map correlates to

5×100000 = 500000 cm in reality.

100 cm = 1 m

1000 m = 1 km

so, 500000 / 100 = 5000 m.

5000 / 1000 = 5 km

Answer:

y = 10 between 0 and 1

AND

y=15x for x>=1

Step-by-step explanation:

This has 2 segments. One when 0 < x < 1 (y=$10), and one when x >= 1 (y=$15x)

So

y = 10 between 0 and 1

AND

y=15x for x>=1

Answer:

1/12

Step-by-step explanation:

The reciprocal of any given x is 1/x. That makes the reciprocal of 12, 1/12.

Answer:

1/12

Step-by-step explanation:

12 is also written as 12/1, therefore to find the inverse of 12/1 the denominator now becomes the numerator and vice versa

Answer:

[tex] \frac{x - 6}{3} = 5 \\ x - 6= 3 \times 5 \\ x - 6 = 15 \\ x = 15 + 6 \\ x = 21 \\ thank \: you[/tex]

The value of the positive integer N, such that deleting its last digit decreases it by 2021, is 2245. That is, [tex]N=2245[/tex].

Given: A positive integer N such that deleting the last digit of N decreases it by 2021

To find: The value of N

Let x be the integer consisting of all digits of N except the last digit and let the last digit of N be d.

Then, [tex]N=10x+d[/tex]

It is given that deleting the last digit  decreases it by 2021

Then, [tex]x=N-2021[/tex]

Substitute [tex]N=10x+d[/tex] in [tex]x=N-2021[/tex] to get,

[tex]x=10x+d-2021[/tex]

[tex]d=2021-9x[/tex]

Since d is a digit, we have,

[tex]0\leq d\leq 9[/tex]

Substitute [tex]d=2021-9x[/tex] in [tex]0\leq d\leq 9[/tex] to get,

[tex]0\leq 2021-9x\leq 9[/tex]

[tex]9x\leq 2021\leq 9x+9[/tex]

[tex]9x\leq 2021\leq 9(x+1)[/tex]

[tex]x\leq \frac{2021}{9} \leq x+1[/tex]

[tex]x\leq 224.5556 \leq x+1[/tex]

Then,

[tex]x\leq 224.5556[/tex] and [tex]224.5556 \leq x+1[/tex]

[tex]x\leq 224.5556[/tex] and [tex]x\geq 223.5556[/tex]

[tex]223.5556 \leq x \leq 224.5556[/tex]

Since x is an integer, the only possibility that satisfies the above inequality is, [tex]x=224[/tex]

Substitute [tex]x=224[/tex] in [tex]d=2021-9x[/tex] to get,

[tex]d=2021-9(224)[/tex]

[tex]d=2021-2016[/tex]

[tex]d=5[/tex]

Substitute [tex]x=224[/tex] and [tex]d=5[/tex] in [tex]N=10x+d[/tex] to get,

[tex]N=2245[/tex]

Thus, the value of the positive integer N, such that deleting its last digit decreases it by 2021, is 2245. That is, [tex]N=2245[/tex].

but he has 85 movies

that are about 9350 minutes runtime which is about 155.8 hours of film

Step-by-step explanation:

Answer:

Step-by-step explanation:

First step plug the numbers into the equation.

-10/(5+2) = (-10/5) + (-10/2)

Solve both sides of the equation separately.

-10/(5+2) Use distributive property, multiply both 5 and 2 by -10.

= -50 + (-20) = -70

-10/5 + -10/2 Multiply the fractions so they can be added together.

-10/5*2 = -20/10  -10/2*5 = -50/10

-20/10 + -50/10 = -70

Now you have solved both equations and they are both equal to -70, so you have verified that the equations are equal to each other because they both equal -70.

what nice question that we can understand ok

Answer:

The latest time Ruth's family can start their tour in order to make it to dinner on time is 2:50 P.M

Step-by-step

Change:

7h10= 430 mins

1 hour and 25 minutes= 85 mins

2 hours and 5 mintues= 125 mins

- Total time Ruth wants to do before his dinner reservations:

85+ 125+ 50= 260 (mins)

- The latest time Ruth's family can start their tour in order to make it to dinner on time:

430- 260= 170 (mins)

Change: 170 mins= 2 hours and 50 minutes

Good luck!

Answer:

A and D

Step-by-step explanation:

Answer:

First, find the value of x:

[tex]h(5-x)=h(9)\\5-x=9\\-x=9-5\\-x=4\\x=-4[/tex]

Substitute the x-value in to the function [tex]x^{2}+x+1[/tex] and solve:

[tex](-4)^{2}+(-4)+1=16-4+1=12+1=13[/tex]

Therefore, the value of h(9) = 13.

Hope this is correct O-o

Answer:

A

Step-by-step explanation:

Since we need to find the value of h(9), we can substitute the (5-x) part from the original equation with 9 to get the value of x, which is 5-x = 9, x = -4. With that, we can go ahead and plug the x into the right side of the equation to get (-4)^2 + (-4) + 1, which equals 16 - 4 + 1, which equals 13.
