What is the correct expanded form for the number 43.205?

40 + 3 + 0.2 + 0 + 0.005
40 + 3 + 0.02 + 0.005
40 + 3 + 0.2 + 0.05
Please help !

Answers

Answer:

43.205 in expanded form:B. 40 + 3 + 0.2 + 0 + 0.005

Answer: Choice B)  40 + 3 + 0.2 + 0 + 0.005

Explanation:

The number 43 is basically 40+3

We read "43" as "forty three", in which you can think of having 40 and then an additional 3 on top of that to get 40+3 = 43 overall.

As for the decimal portion, we do the same sort of thing.

The 0.205 breaks up into 0.2 + 0.005

0.2 = 2 tenths

0.005 = 5 thousandths

So that's why 43.205 breaks down into 40+3+0.2+0+0.005; each place value digit corresponds to a term in that expanded sum.

A tarp is used to keep the infield of a baseball field from getting wet. The infield is a square. The corners of the square tarp are anchored at each base. The tarp is 8,100 square feet.
A. What is the distance between the first and second base?
B. Is 8,100 a perfect square? Explain.

Answers

I’ll do my best, but...

A. Since the area is 8100 sq ft and the shape is a square (area of a square = length x width) you take the square root of 8100 and get 90 ft as one of the sides. (90 ft x 90 ft = 8100 sq ft)

B. Yes, 8100 is a perfect square. A perfect square is a number made by squaring a whole number. It’s also the product of 2 equal integers. In this case, it’s 90.

The question is really asking what the slope (m) of the line is. Here’s the answer:

Slope= the variable m

m=rise/run; m=change in y/change in x

We need to find the rate of how much the taxi driver charges per minute.

Therefore:

We need to pick a precise point on the line ( a precise point is a point with whole number x and y coordinates; no decimals or fractions).

We see that the point (6, 9) is precise.

A rate is a ratio in the form of a fraction that shows the relationship of change between two quantities: a/b.

So, the taxi costs 9 dollars / 6 minutes.

9/6 simplifies 2/3.

And thus, the taxi charges 2 dollars per 3 minutes

So, the answer is 9/6, which can be simplified to the furthest possibility, making it a unit rate.

Answer: 9/6

solve the following system y=4x and 6x-4y=10

Answers

Answer:

x=-1 y=-4

Step-by-step explanation:

y = 4x
6x - 4y = 10

Use substitution method:

Substitute y = 4x into the 2nd equation:

6x - 4(4x) = 10
6x - 16x = 10
-10x = 10

-10x/-10 = 10/-10

x = -1


Substitute x = 1 into the 1st equation to solve for y:

y = 4x
y = 4(-1)
y = -4

Therefore, the solution to the systems of linear equation is:

(-1, -4) or x = -1, y = -4

640 divided by 2/5 how do I solve this

Answers

Answer:

Step-by-step explanation:

1600

Answer:

1,600

Step-by-step explanation:

When dividing with fractions, remember this rule!!!!

KEEP SWITCH FLIP

- Keep the first fraction

- Switch the sign from division to multiplication

- Flip the second fraction so it becomes its reciprocal (the numerator becomes the denominator and the denominator becomes the numerator)

Let's begin!

640 ÷ 2/5

We know that every number divided by 1 is itself, thus every numerator has an invisible 1 as its denominator. Now we can rewrite it as:

640/1  ÷ 2/5

First, keep 640/1. Then change the ÷ into a ×

640/1 × 2/5

Next, flip the 2/5 so the 5 is on top and 2 is on the bottom

640/1 × 5/2

And multiply across!

640 × 5 = 3,200

1 × 2 = 2

3,200/2 = 1,600

Your answer is 1,600!!

Hope this helps clear things up for you. Let me know if you any other questions :D

1.-2q-5=-11


2.w/3+2=5

Answers

Answer:

1. q = 3

2. w = 9

Step-by-step explanation:

1.

-2q - 5 = -11

Add 5 to both sides:

-2q - 5 + 5 = -11 + 5

-2q = -6

Divide both sides by 2:

-2q ÷ 2 = -6 ÷ 2

-q = -3

Divide both sides by -1:

-q ÷ -1 = -3 ÷ -1

q = 3

2.

w/3 + 2 = 5

Subtract 2 from both sides

w/3 = 3

Multiply both sides by 3:

w = 9

What's the slope of (1, 4) and (0, 11) ?​

Answers

Answer: Slope = -7

Concept:

Here, we need to know the formula that helps to find the slope by two points.

The slope of a line is a number that describes both the direction and the steepness of the line.

Slope = Δy / Δx = (y₂ - y₁) / (x₂ - x₁)

Solve:

Given information

(x₁, y₁) = (1, 4)

(x₂, y₂) = (0, 11)

Given expression

Slope = (y₂ - y₁) / (x₂ - x₁)

Substitute values into the expression

Slope = (11 - 4) / (0 - 1)

Simplify the values in the parentheses by subtraction

Slope = (7) / (-1)

Simplify by division
