Answer:

  20 + 3x ≥ 50

Step-by-step explanation:

After x days, John will have added 3x points to his total. The new total will be ...

  20 +3x

We want that value to be at least 50, so we use the symbol "greater than or equal to" to express that relationship:

  20 +3x ≥ 50

_____

Brainly makes available a table of math symbols so you can choose the appropriate one to use in your expression. The number 2 is not the same as the symbol ≥. Using incorrect symbols makes it very difficult to tell what the intended problem is.

Answer:

20 +3x ≥ 50

Step-by-step explanation:

<h2><u>INEQUALITIES </u></h2>

since john already has 20 points this would be added to the points he is yet to receive

3 points if he goes to the shop once a day for x days

means 3x

because 3 points multiplied  by the number of days he went to the coffee shop

<em>AT LEAST 50 means</em>

≥50

now we can create the equation

<u>20 + 3x ≥ 50 </u>

svetlana [45]

Answer:

Part a) 160\ gallons

Part b) 480\ gallons

Step-by-step explanation:

Part a) How many gallons of water will be in the pool after 20 minutes?

we know that

Using proportion

\frac{40}{5}\frac{gallons}{minutes}=\frac{x}{20}\frac{gallons}{minutes} \\ \\x=40*20/5\\ \\x=160\ gallons

Part b) How many gallons of water will be in the pool after 1 hour

we know that

1 hour = 60 minutes

Using proportion

\frac{40}{5}\frac{gallons}{minutes}=\frac{x}{60}\frac{gallons}{minutes} \\ \\x=40*60/5\\ \\x=480\ gallons

Find the area of the circle to the<br> nearest tenth. Use 3.14 for it<br> (11 mm)
Nikolay [14]

Answer:

The area of the circle is 379.94 mm²

Step-by-step explanation:

To solve this problem we need to use the area formula of a circle:

a = area

r = radius = 11 mm

π = 3.14

a = π * r²

we replace with the known values

a = 3.14 * (11 mm)²

a = 3.14 * 121 mm²

a = 379.94 mm²

Round to the nearest tenth

a = 379.94 mm² = 379.9 mm²  

The area of the circle is 379.9 mm²
