Annie and her family are on their way to visit some family friends who live 820 miles away from them. Based on the route they choose, they expect to complete their trip in three days. The distances and average speeds for the first two days driven are show below. First day: 6 hours at an average speed of 60 miles per hour Second day: 4 hours at an average speed of 65 miles per hour If the average speed on the third day is 50 miles per hour, how many more hours will it take for them to reach their family friends home?

Answer:

I got this! Basically, the instructions say 12 gallons per 3 minutes. So you plug in the 12/3 to find the ratio of how many gallons per 1 minute.

Step-by-step explanation:

So, for the chart you just mulitply and evauluate

Time (min)           | 2 |  3 |  4 |   5  |   6 |

Water used (gal) | 8 | 12 | 16 | 20 | 24 |

Answer:

Step-by-step explanation:

a) 16^ (-1/4)=2^4(-1/4)=2^-1=1/2

b) 27*9^3x=

we write 27=3^3

9=3^2*3x=3^6x

3^3 x 3^6x=   k=3+6x

Answer:

3 and 8

Step-by-step explanation:

3 and 8 because 8 can only divide by 2 or four and get 4 and 2, and 3 can not get to any of these number.

Answer:

4+8+10+6=28

Step-by-step explanation:

Answer:

100feet

Step-by-step explanation:

Given the height of the object modelled by the equation

y = -16x^2 + 48x + 64

We can find the maximum height reached by the object since we are not told what to find.

The velocity of the object at its max height is zero.

dy/x = 0

dy/dx = -32x + 48

0 = -32x + 48

32x = 48

x = 48/32

x = 1.5secs

get the max height by substituting x = 1.5 into the given equation:

y = -16x^2 + 48x + 64

y = -16(1.5)^2 + 48(1.5)+ 64

y =  -36+72+64

y = 100 feet

Hence the maximum height reached by the object is 100feet

17/20 = t + (- 13/20)

t = 17/20 + 13/20

t = 30/20

t = 1.5

Answer:

[tex]p =4[/tex]

Step-by-step explanation:

Given

Variation: Inversely

[tex]p = 12[/tex] when [tex]q = 45[/tex]

Required

Determine p when [tex]q = 135[/tex]

First, we need to determine the relationship between p and q

Since, it is an inverse variation.

The relationship is:

[tex]p\ \alpha\ \frac{1}{q}[/tex]

Convert to an equation

[tex]p= k *\frac{1}{q}[/tex]

[tex]p= \frac{k}{q}[/tex]

Where k = constant of variation

Make k the subject

[tex]k = p * q[/tex]

When [tex]p = 12[/tex] and [tex]q = 45[/tex]

[tex]k = 12 * 45[/tex]

[tex]k = 540[/tex]

To solve for p when q = 135

Substitute 135 for q and 540 for k in [tex]p= \frac{k}{q}[/tex]

[tex]p = \frac{540}{135}[/tex]

[tex]p =4[/tex]

Answer:

the square of -5 is 25 not -25

, -4(1)(-3) is 12 not -12 because when we multiply 2 negative numbers their result is positive

+5 should be written instead of -5

Step-by-step explanation:

+5 should be written instead of -5 as the formula is (-b+-(b²-4ac)½)/2a . since b=-5 ;-b=+5

Answer:

(8,3)

Step-by-step explanation:

if there is a words left and down on our question we will decrease a given number from the coordinates.

but if we have words like right and up in our question, then we will increase the given number on the coordinate given.

so X= 3+5=8

Y= 5-2=3

A(8,3)

1.) No

2.) No

3.) Yes

4.) Yes.

Answer:

Step-by-step explanation:

Let's solve for x.

1.5x+0.5y=12

Step 1: Add -0.5y to both sides.

1.5x+0.5y+−0.5y=12+−0.5y

1.5x=−0.5y+12

Step 2: Divide both sides by 1.5.

1.5x

1.5

=

−0.5y+12

1.5

Add the total of the 3 things bought and subtract from what they gave the cashier:

20.34 + 24.08 + 5.08 = 49.50 total

50 - 49.50 = 0.50

The shopkeeper kept 0.50
