What is the slope intercept form when m = 1/2 & b = 89 ?
Helppppppppp

Answers

Answer:

[tex]y = \frac{1}{2}x + 89[/tex]

Step-by-step explanation:

slope-intercept form: y  = mx + b

y = (x , y)

x = (x , y)

m = slope = 1/2

b = y-intercept = 89

Plug in the corresponding numbers & variables to the corresponding variables:

y = (1/2)x + 89

[tex]y = \frac{1}{2}x + 89[/tex]  is your answer.

Allex has a $20 bill. At the corner store, he buys a
bag of Hot Fries for $1.99 and 6 packs of gum. He
gets $11.77 in change. What is the price of one
pack of gum?

Answers

Answer:

First we need to subtract the hot fries. 20 - 1.99 = 18.01

he gets 11.77 so lets subtract it is 6.94 left so now divide by 6 is 1.5666666 or 1.6 per pack

Rafiq is makeing a fruit punch using 48 ounces of grape juice abd some seltzer water. He wants to make 10 equal servings that are atleast 9 ounces each. Should he add 32 ounces of seltzer water or 48 ounces of seltzer water

Answers

Answer:

48 ounces of seltzer water

Step-by-step explanation:

From the question, we are told that:

Rafiq is making a fruit punch using 48 ounces of grape juice and some seltzer water.

He wants to make 10 equal servings that are at least 9 ounces each.

The total number of ounces that he want so have is at least

= 10 × 9 ounces = 90 ounces

Should he add 32 ounces of seltzer water or 48 ounces of seltzer water?

Let the number of ounces of seltzer water that he wants to add = x

At least = More than or equal to which is represented by inequality sign = ≥

Hence:

48 ounces of grape juice + x ounces of seltzer water ≥ 90 ounces

48 + x ≥ 90

x ≥ 90 - 48

x ≥ 42 ounces of seltzer water

From this calculation, the least amount of seltzer water he can add is 42 ounces.

Therefore, Rafiq should add 48 ounces of seltzer water

Pls help

Answers

Option D is the correct option.

What is Mean Absolute Deviation?

'The mean absolute deviation (MAD) is the mean (average) distance between each data value and the mean of the data set.'

According to the given problem,

The mean height Variety A = 19 [ from the table ]

The mean height of variety B = 13 [ from the table ]

The spread is given by the mean absolute deviation, which 1.2 for Variety A and 2.4 for Variety B. So we can see that, the spread in Variety A is lesser than the spread in Variety B, which shows that the average height of Variety A varies less than the average height of Variety B.

We can see from the table that the average height of a variety A is indeed greater than that of Variety B. Also we can see that the Mean Absolute deviation of Variety A is 1.2 which is lesser than the Mean Absolute deviation of Variety B.

Hence, option D is correct since the average height of Variety A is greater than Variety B, and also the mean varies lesser in Variety A than in Variety B.

An airplane takes 3 hours to travel a distance of 2700 miles with the wind. The return trip takes 5 hours against the wind. Find the speed of the plane in still air and the speed of the wind.

Answers

Answer:

720 mph, 180 mph

Step-by-step explanation:

Let the speed of the plane is x, speed of the wind is y

Speeds add up when in directions are same and subtract when opposite

Then as per the given we have equations:

3( x + y) = 27005(x - y) = 2700

Simplify the equations:

x + y = 900x - y = 540

Sum the two equations and solve for x:

2x = 900 + 5402x = 1440x = 720 mph

Find the value of y:

y = 720 - 540 = 180 mph

Speed of the plane is 720 mph

Speed of the wind is 180 mph

Graph DEF and its image when you translate DEF using vector

Answers

Answer:

The image coordinates are D'(8, 5), E'(12, 3) and F'(10,0)

Step-by-step explanation:

Given the vertices of △ DEF are D (2, 5), E (6, 3), and F (4, 0). We have to translate the triangle using the vector (6, 0)

Now, translation by vector (6, 0)

D (2, 5)=D'(2+6, 5+0)=D'(8, 5)

E (6, 3)=E'(6+6, 3+0)=E'(12, 3)

F (4, 0)=F'(4+6, 0+0)=F'(10,0)

Now, we have to label the coordinate of the triangle or to get image of triangle after translation.

Hence, The image coordinates are D'(8, 5), E'(12, 3) and F'(10,0)
