Answer:

distance = 80 miles

Step-by-step explanation:

The rate is distance over time

rate = 15 miles/ 90 minutes

Converting the minutes to hours

90 minutes * 1 hours / 60 minutes = 1.5 hours

rate = 15 miles / 1.5 hours = 10 miles/ hour

We know distance rate * time

She rides 8 hours per week

distance = 10 miles / hour * 8 hours

distance = 80 miles

A wooden board 100 centimeters long is cut into two pieces. One piece is 16 centimeters longer than the other. What are the leng
Bezzdna [24]

x = the length of one piece

y = the length of the other piece


the total length is 100 cm this means 


x + y = 100


one piece is 16 inches longer than the other


first we need to convert inches to cm: 


1 in = 2.54 cm

16 in = 2.54*16 = 40.64


now we can write


x = y + 40.64


by solving the system of equations


x + y = 100

x = y + 40.64


we find


x = 70.32 cm


y = 29.68 cm


the lengths of the two pieces are 70.32 cm and 29.68 cm.

puteri [66]

Answer:

Hello...... here is a solution :

1 -  

Hello:

the   equation of "m" is : y = ax+b

the slope is a : a×(- 2/3) = -1......( perpendicular to a line : y=-2/3x+6 when the slope is -2/3 )

a = 3/2          

the line " n" that passes through (4, - 3) and  parallel to line "m" :  

when the slope is 3/2 ( same slope )

the equation in slope-intercept form of the line" n" is :

 y – (-3)= (3/2)(x – 4)

Screen sizes for televisions are measured by the diagonal length from one corner to the opposite corner on the other side. After
JulsSmile [24]

Answer:

<h2>18/√3ft</h2>

Step-by-step explanation:

This is a ratio problem

Step one:

Given the ratio of length:width is <em> "3 space colon space square root of 3"</em>

mathematically it is expressed as

length:width 3:√3 or 3/√3

Step two:

3:√3 or 3/√3

if the built TV has a width of 6ft let the length be x

3/√3=x/6

cross multiply we have

x√3=3*6

x√3=18

x=18/√3ft

therefore the length will be 18/√3ft
