what is the distance between (-8,5) and (-1,5)

Answers

Answer:

7 units

Step-by-step explanation:

(see attached for reference)

given two points (x₁, y₁) and (x₂, y₂), the formula for distance between two points is given as

Distance, D = √( (x₂-x₁)² + (y₂-y₁)² )

in our case, we are given

(x₁, y₁) = (-8,5)

(x₂, y₂) = (-1,5)

simply substitute the values into the equation above:

D = √( (x₂-x₁)² + (y₂-y₁)² )

= √{ [ (-1)-(-8) ]² + (5-5)² }

= √{ [ (-1 + 8) ]² + (0)² }

= √[ (7) ² ]

= 7 units (answer)

Vivian is at a fair in Coachella Valley, California. Much of the valley lies below sea level. Vivian has brought along an altimeter to measure her elevation at different places in the valley. Vivian's first ride was on the Ferris wheel. When she sat on the wheel at its lowest point, her altimeter read -9.6 feet. When she reached the top of the wheel, her altimeter read 12.3 feet.

Answers

Answer:

21.9 feet

Step-by-step explanation:

The question is incomplete. Here is the complete question.

Vivian is at a fair in Coachella Valley, California. Much of the valley lies below sea level. Vivian has brought along an altimeter to measure her elevation at different places in the valley. Vivian’s first ride was on the Ferris wheel. When she sat on the wheel at its lowest point, her altimeter read -9.6 feet. When she reached the top of the wheel, her altimeter read 12.3 feet.

Is the change in Vivian's elevation from the bottom of the Ferris wheel to the top a positive number or a negative number? Why?

Given parameters

Altimeter of vivian at its lowest point = -9.6 feet

Altimeter of vivian at the top of the wheel = 12.3feet

Note that the sea level is at 0 feet.

change in Vivian's elevation from the bottom of the Ferris wheel to the top is expressed as:

= (12.3-0)+(0-(-9.6))

= 12.3+(0+9.6)

= 12.3+9.6

= 21.9 feet

From the gotten value, it can be seen that the change in Vivian's elevation from the bottom of the Ferris wheel to the top is a positive value.

The value is positive because vivian keeps moving to the top of the wheel (above the sea level). The values above the sea level is always positive.

Answer:Hide Sample Answer

The change in Vivian's elevation is a positive number because her elevation increased as she moved from the bottom of the Ferris wheel to the top.

Step-by-step explanation:Hide Sample Answer

The change in Vivian's elevation is a positive number because her elevation increased as she moved from the bottom of the Ferris wheel to the top.

Carlos rode further on Sunday by 3 and StartFraction 51 over 56 EndFraction miles. Carlos rode further on Sunday by 1 and StartFraction 51 over 56 EndFraction miles.

Answers

Answer:

Carlos rode further on Sunday by [tex]1\frac{51}{56} miles[/tex] miles.

Step-by-step explanation:

Carlos covered distance on Saturday [tex]=\frac{139}{8}[/tex]

He covered distance on Sunday = [tex]\frac{135}{7}[/tex]

Equivalent fractions:

[tex]\frac{139}{8} \times \frac{7}{7}=\frac{973}{56}\\ \frac{135}{7} \times \frac{8}{8}=\frac{1080}{56}[/tex]

So,[tex]\frac{1080}{56}>\frac{973}{56}\\ \frac{135}{7}>\frac{139}{8}[/tex]

So, He covered more distance on Sunday

Difference between distances =[tex]\frac{1080}{56}-\frac{973}{56}=\frac{107}{56}=1\frac{51}{56}[/tex]

So, Carlos rode further on Sunday by [tex]1\frac{51}{56} miles[/tex] miles.

1. Yearly membership with the online music club costs $48. Members pay $0.99 per song to download music. Nonmembers may download songs for $1.29 each.

Answers

Answer:

160 musics

Step-by-step explanation:

let the total amount/charges be y

let the number of musics be x

For members total

y=48+0.99x-------1

For non-members total

y=1.29x-------------2

we are expected to solve for the number of music where members and non members get to pay the same amount

equating 1 and 2 we have

48+0.99x=1.29x

48=1.29x-0.99x

48= 0.3x

x=48/0.3

x=160 musics
