the distance between two cities on a map is 3.5 centimeters. The map uses a scale in which 1 centimeter reprecents 20 kilometers. what is the actual distance between these two cities in kilometers?

Answers

Answer:

70 kilometers

Step-by-step explanation:

Set up a proportion where x is the actual distance

[tex]\frac{1}{20}[/tex] = [tex]\frac{3.5}{x}[/tex]

Cross multiply:

x = (20)(3.5)

x = 70

So, the actual distance is 70 km

Answers

Answer:

Step-by-step explanation:

The required expression represents the number of the small marbles, medium marbles, and large marbles are m = 4s  and l = 3 + 5m.


What is arithmetic?

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,

Here,
Let the number of small marbles be s, medium marbles are m and large marble is l.
According to the question,
He has four times as many small marbles as medium marbles. The number of large marbles is three more than five times the number of medium marbles.
m = 4s
and
l = 3 + 5m


Thus, the required expression represents the number of the small marbles, medium marbles, and large marbles are m = 4s  and l = 3 + 5m.

6x - 8y = 12 and 5x + 8y = -1 Solve using elimination​

Answers

Answer:

Step-by-step explanation:

6x-8y=12

5x+8y=-1

add them

11x=11

x=1

y=-3/4

Answer:

(1,-3/4)

Step-by-step explanation:

Luckily, y is already opposites, so it should be easier:

6x-8y=12

5x+8y=-1    

Combine; This should end up with y eliminated -

11x = 11

x = 1

Now we can plug 1 in for x in one of the equations to find y. I'm going to use the second one.

5(1) +8y = -1

5+8y=-1

8y=-6

y=-6/8 (you can simplify)

water cost $2 for 8 bottles orange juice cost a $1.50 for 3 bottles which is more expensive per bottle ​

Answers

I believe you can use ratios and multiply both of them like fractions to get the same amount of bottles and compare the prices fairly.


2:8 = 2/8
1.5:3 = 1.5/3


(2/8)3 = 6/24 or $6 per 24 bottles
(1.5/3)8 = 12/24 or $12 per 24 bottles


In conclusion, the latter ($1.50 for 3) costs more than the $2 per 8.


Answer:

orange juice

Step-by-step explanation:

1 water -> 2÷8

                = 0.25

1 orange juice ->1.50 ÷ 3

                    = 0.50

hence, orange juice is more expensive

Answers

Answer:

Step-by-step explanation:

By the Pythagorean Theorem a^2+b^2=c^2 or the sum of the squared sides is equal to the hypotenuse squared.

41^2=9^2+h^2

h^2=41^2-9^2

h^2=1600

Answers

Answer:

The side of the hypotenuse is 12.233 centimeters.

Step-by-step explanation:

The triangle presented in the figure represents a right triangle, we know an angle and a leg adjacent to such angle and we need to determine the length of the hypotenuse, which is found by this trigonometric relation:

[tex]\cos 56^{\circ} = \frac{7.4\,cm}{x}[/tex] (1)

Where [tex]x[/tex] is the length of the hypotenuse, measured in centimeters.

Then, we clear the variable within (1):

[tex]x = \frac{7.4\,cm}{\cos 56^{\circ}}[/tex]

[tex]x = 13.233\,cm[/tex]

The side of the hypotenuse is 12.233 centimeters.
