that be?

Answer:

  5 minutes; 60 gallons

Step-by-step explanation:

The volume in tank A is initially 35 gallons. Its rate of change is 5 gallons per minute. The equation for volume can be written as ...

  y = 35 +5x . . . . . . where y is gallons, and x is minutes

The volume in tank B is initially 100 gallons. Its rate of change is -8 gallons per minute. The equation for volume can be written as ...

  y = 100 -8x

We want to find the values of x and y such that both are the same for both tanks.

  35 +5x = y = 100 -8x

  13x = 65 . . . . . . . . add 8x-65 to both sides of the equation

  x = 5

  y = 100 -8·5 = 60

Both tanks will hold 60 gallons after 5 minutes.

Use the point-slope formula below to write an equation of a line passing
through (1, -3) that is parallel to the line y = –2x + 5. Make sure your
final answer is in slope-intercept (y=mx+b) form.

Answers

Step-by-step explanation:

x intercepts = (5/2, 0)

y intercepts = (0,5)

slope = -2

the line y = -2x-5 has a slope of -2 and parallel lines have the same slope

y + 3 = -2( x-1)

y + 3 = -2x + 2

answer: y = -2x -1

5 small bucket and 2 large bucket of water make 20 liter.three small bucket and 2 large bucket make only 18 liter.how much water each bucket hold?​

Answers

9514 1404 393

Answer:

  small: 1 liter; large: 7.5 liters

Step-by-step explanation:

The difference between the two sets of buckets is 2 small buckets and 2 liters. Hence we know that a small bucket is 1 liter.

Then 5 small buckets contribute 5 liters to the 20-liter total. The remaining 15 liters comes from 2 large buckets, so each of those is 7.5 liters.

Large bucket: 7.5 liters

Small bucket: 1 liter

What is an equation of the line that passes through the point (-2,7) and is perpendicular to the line x-4y=24

Answers

y = -4x - 1

Step-by-step explanation:

x - 4y = 24

-4y = -x + 24

y = [tex]\frac{1}{4}[/tex]x - 6

m⊥ = -4

y = -4x + b

7 = -4 ( -2 ) + b

An ice cream shop offers 3 ice cream flavors and 3 types of syrup,and 2 toppings for sundaes . How many different ways are there to make a sundae with one ice cream flavor, one type of syrup, and one topping.

Answers

Given:

Types of ice cream = 3

Types of syrup = 3

Toppings for sundaes = 2

To find:

The number of difference ways to make a sundae with one ice cream flavor, one type of syrup, and one topping.

Solution:

We have,

Total number of ways to select 1 form 3 ice cream flavor = 3 ways

Total number of ways to select 1 form 3 syrup = 3 ways

Total number of ways to select 1 form 2 toppings = 2 ways

Now, the total number of ways is

[tex]\text{Total ways}=3\times 3\times 2[/tex]

[tex]\text{Total ways}=18[/tex]

Therefore, the total number of difference ways to make a sundae with one ice cream flavor, one type of syrup, and one topping is 18.

The sum of three consecutive even numbers is 582. What is the 1st number?

Answers

Answer:

192

Step-by-step explanation:

Answer: The first number is 192 .

Step-by-step explanation:

Let the three consecutive even numbers

be x , x+2 and x +4 .  

Their sum = 582

x + (x+2) + (x+4) = 582

x =  

x = 192

First number = 192

Second number = 192 + 2 = 194

Third number = 192 + 4 = 196
