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

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

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
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.

solve the following system y=4x and 6x-4y=10
Answers
Answer:
x=-1 y=-4
Step-by-step explanation:
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

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 is the correct expanded form for the number 43.205?
400 + 3 + 0.2 + 0 + 0.005
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 + 0.005Explanation:
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.
