A car that travels 20 miles in LaTeX: \frac{1}{2}1 2 hour at constant speed is traveling at the same speed as a car that travels

30 miles in LaTeX: \frac{3}{4}3 4 hour at a constant speed. Both cars go miles in LaTeX: \frac{1}{4}1 4of an hour (or 15 minutes). Both cars will travel miles in 1 hour.

Answer:

10 miles per 1/4 hour

40 miles per hour

Step-by-step explanation:

Given that:

A car travels 20 miles in 1/2 hour

Miles traveled per hour :

(20 * 2) / 1 = 40 miles per hour

Mile traveled in 1/4 hour :

Distance = speed * time

Distance = 40 mph * 1/4 = 10 miles per 1/4 hour

Car traveling 30 miles in 3/4 hours

(30 * 4) /3 = 120 / 3 = 40 miles per hour

Distance = 40 mph * 1/4 = 10 miles per 1/4 hour

PLEASE HELP ME IM SO CONFUSED The volume of a cube is x³ cubic units. The surface area of the cube is x³ square units. What is t
Tom [10]

Answer: The value of x is 6.

Step-by-step explanation:

TO find the volume of a cube you cube any side length. so if the side  length is 6.

6^3 = 216

To find the surface area of a cube you will square one of the side lengths and multiply it by 6.

so the side length is 6 and 6 squared is 36

36*6 = 216

Given line AB and point O on that line, any ray that can be drawn with its endpoint at O can be put into a one- to-one correspon
natima [27]

Answer:

Protractor

Step-by-step explanation:

A POSTULATE, LAW OR THEORY SHOULD NEVER BE ALTERED

∴ The protractor postulate states that the measurement of an angle between two rays can be designated as a unique number, and this number would be between 0 and 180 degrees, Hence for every angle A, there corresponds a positive real number less than or equal to 180. This postulate guarantee the use of a protractor to measure angles.

Hence, Given line AB and point O on that line in such a way that any ray that can be drawn with its endpoint at O can be put into a one- to-one correspondence with the real numbers between 0 and 180 is a statement that explains Protractor's Postulate.

PLS HELP!! AND HURRY!! Find an expression for the nth term ( tn ) in each of the following sequences:
fiasKO [112]

If the pattern continues, so that each term is separated by a distance of 3, then the sequence is given by the recursive rule

\begin{cases}a_1=1\\a_n=a_{n-1}+3&\text{for }n>1\end{cases}

From this definition, we can write a_n in terms of a_1:

a_2=a_1+3

a_3=a_2+3=(a_1+3)+3=a_1+2\cdot3

a_4=a_3+3=(a_1+2\cdot3)+3=a_1+3\cdot3

a_5=a_4+3=(a_1+3\cdot3)+3=a_1+4\cdot3

and so on, up to

a_n=a_1+(n-1)\cdot3

(notice how the subscript on <em>a</em> and coefficient on 3 add up to <em>n</em>)

or

a_n=1+3(n-1)=3n-2

Find distance (4,7) (-4,-3)​
AURORKA [14]

∆x = (4--4)=8

∆y = (7--3)= 10

Step-by-step explanation:

distance is given by;

d² = (∆y)²+ (∆x)²

d = √((∆y)²+ (∆x)²)

d = √((4+4)² + (7+3)²)

d = √((8²) + (10²))

d = √(64+100)

d = √164

<em><u>d =12.806 units</u></em>
