The ratio of BMX bikes in a sporting goods store to mountain bikes is 3 to 2. The store
has 90 BMX bikes. How many mountain bikes does the store have?

Answers

BMX: 3 to 2

BMX:90 to 60

90x2=180 180÷3=60

Answer: 60

The store has 60 mountain bikes if there is ratio of BMX bikes in a sporting goods store to mountain bikes is 3 to 2.

What is Ratio?

An ordered pair of numbers a and b, written a / b where b does not equal 0 is called ratio.

The ratio of BMX bikes to mountain bikes in the store is 3 to 2.

Which means that for every 3 BMX bikes, the store has 2 mountain bikes.

It is given that the store has 90 BMX bikes.

Let us set up a proportion to find the number of mountain bikes:

3 BMX bikes / 2 mountain bikes = 90 BMX bikes / x mountain bikes

where x is the number of mountain bikes.

Now solve for x

3 BMX bikes × x mountain bikes = 2 mountain bikes × 90 BMX bikes

3x = 180

Divide both sides by 3

x = 60

Therefore, the store has 60 mountain bikes.

Mt. Everest, the highest elevation in Asia, is 29,028 feet above sea level. The Dead Sea, the lowest elevation, is 1,312 feet below sea level. What is the difference between these two elevations? Show your work

Answers

Answer:

30,340 feet above sea level is the correct answer.

Step-by-step explanation:

To find the difference to between the two sea levels, subtract the lowest quantity (or the elevation of the Dead Sea) to the largest quantity (or the elevation of Mt. Everest.)

However, in this situation, you must also add the quantity of the above sea level to the subtraction, since the lower quantity is above sea level.

29,028 - 29,028 = 0

Now, we must subtract the lower quantity of 1,312.

0 - 1,312 = -1,312

If this was to be represented on a number line, the difference between our work relates to the absolute value, or the amount of spaces a number is from 0. Even though this is a negative number, you can take away the sign (if there is any) from in front of the number, and the absolute value will still be 1,312.

To find the total difference, add 29,028 to 1,312.

29,028 + 1,312 = 30,340

Therefore, our final answer is 30,340 feet above sea level.

Answer:9 ounces

Step-by-step explanation:

So first you want to start off with what you know

2/9 of a swerving is 2 ounces of pasta

Which aslo lets you know 1/9 of a serving = 1 ounce of pasta

Hey everyone i need your help again what's 3(11x + 5) = 279

Answers

Answer:

x = 8

Step-by-step explanation:

We can use PEMDAS to solve algebraic equations:

Parentheses

Exponents

Multiplication/Division

Addition/Subtraction

First, we have parentheses in this equation, so distribute

3(11x) + 3(5) = 279

Next, because there are no exponents, multiply

33x + 15 = 279

To isolate x, subtract 15 from both sides

33x + 15 - 15 = 279 - 15

33x = 264

Then divide both sides by 33

x = 8

Write the subtraction expression as an equivalent addition expression and then evaluate it.

And a real-world situation represented in the table is “A jet airplane is traveling at 450 mph.”

What is a slope?

In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction.

If a line passes through two points (x₁ ,y₁) and (x₂, y₂) ,

then the equation of line is

y - y₁ = (y₂- y₁) / (x₂ - x₁) x (x - x₁)

To find the slope;

m =  (y₂- y₁) / (x₂ - x₁)

Given that a table.

To find the correct statement about the table:

The data points in the table represent the linear function,

The function passes through two points (1, 450) and (2, 900),

then the equation of the line is,

y - 450 = (900 - 450)/((2 - 1) (x - 1)

y - 450 = 450x - 450

y = 450x

when x = 5, y = 2250.

From the given choices,

The missing value in the last row is 2,250.

And a real-world situation represented in the table is “A jet airplane is traveling at 450 mph.”
