-3/7 divided by 1/2
Answers
Answer:
-0.85714285714
Step-by-step explanation:
With a calculator or even by hand, you can divide the two numbers and find the solution. If you want to round up your answer is 0.86.
Hoping this answers your question!
Answer:
6/7≅ -0.8571429
Divide: -3/
7: 1/2
= -3/7
· 2/1
= -3 · 2/7 · 1
= -6/7
Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 1/2
is 2/1
) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. In the following intermediate step, it cannot further simplify the fraction result by canceling.
In other words - minus three-sevenths divided by one half = minus six-sevenths.

What is the area of the blue shaded figure if A=28 cm and B=14 cm?
Use 3.14 to approximate π.
Answers
Answer:
153.86\(cm^{2}\)
Step-by-step explanation:
For the white semicircles:
B=14cm is also the diameter, we know r=1/2diameter, so r=1/2(14)=7
Awhite=1/2π\(r^{2}\)
Awhite=1/2π(\(7^{2}\))
Awhite=76.93\(cm^{2}\)
For the blue semicircle:
B=14cm is also the radius
Ablue=1/2π\(r^{2}\)
Ablue=1/2π(\(14^{2}\))
Ablue=307.72\(cm^{2}\)
Shaded area:
Ashaded=Ablue-2(Awhite)
We use this equation since there are two white semicircles.
Ashaded=307.72-2(76.93)
Ashaded=153.86\(cm^{2}\)
Answer:
615.44cm^2
Step-by-step explanation:
the big semicircle has a radius of 28cm
then you find the area of the big semicircle which is 1/2 x 28^2 x pi
pi=3.14
28^2=784
1/2 x 784 x 3.14=1230.88
the small semicircle has a radius of 14cm
1/2 x 14^2 x pi
1/2 x 196 x 3.14=307.72
since there are two small semicircle you need to times 307.72 by 2
307.72 x 2=615.44
now to find the area of the blue shaded you need to do
1230.88-615.44=615.44cm^2

Quadrilateral PQRS was translated 5 units to the right and 3 units up to create quadrilateral P'Q'R'S'. Which rule describes this transformation?
A: (x, y) → (x−5, y−3)
B: (x, y) → (x+5, y+3)
C: (x, y) → (x−3, y−5)
D: (x, y) → (x+3, y+5)
Answers
Answer:
B
Step-by-step explanation:
As Quadrilateral PQRS was translated 5 units to the right and 3 units up to create quadrilateral P′Q′R′S′.
Therefore, we can conclude that the rule '' A rule for a translation right and up (x + __, y + __) '' describes this transformation.
The transformation which describes the quadrilateral P'Q'R'S' is (x, y) → (x+5, y+3). Therefore, option B is the correct answer.
Given that, quadrilateral PQRS was translated 5 units to the right and 3 units up to create quadrilateral P'Q'R'S'.
What is the translation?A translation in math moves a shape left or right and/or up or down. The translated shapes look exactly the same size as the original shape, and hence the shapes are congruent to each other. They just have been shifted in one or more directions.
Translation rules:
When the shape is moved towards the right by k units, then replace x with x + k.
When the shape is moved up by k units, then replace y with y + k.
So, translated 5 units to the right
x → x+5
Translated 3 units up
y → y+3
The transformation which describes the quadrilateral P'Q'R'S' is (x, y) → (x+5, y+3). Therefore, option B is the correct answer.

what value of x makes this equation true -(x+3)=2(x-3)
A. 0
B. 1
C. 2
D. 3
Answers
Answer:
To solve the equation -(x + 3) = 2(x - 3) for x, we can follow these steps:
Step 1: Distribute the negative sign on the left side of the equation:
-(x + 3) = 2(x - 3)
=> -x - 3 = 2(x - 3) (using the distributive property)
Step 2: Expand the right side of the equation:
-x - 3 = 2x - 6
Step 3: Add x to both sides of the equation to isolate the x term on one side:
-x + x - 3 = 2x + x - 6
=> -3 = 3x - 6
Step 4: Add 6 to both sides of the equation:
-3 + 6 = 3x - 6 + 6
=> 3 = 3x
Step 5: Divide both sides of the equation by 3 to solve for x:
3/3 = 3x/3
=> 1 = x
So, the correct value of x that makes the equation true is B. 1.
PLEASE MARK BRAILYISTT :D
Answer:
B, one
Step-by-step explanation:
In order to solve this, you can solve the equation. First, you can use the distributive property to get -x-3=2x-6. If you make the variables on one side and the constants on the other, you will get -3x-3=-6. This can further simplify to -3x=-6. Divide both sides by -3 to get that x=1. Then, the correct answer is B.

There are currently 6,210 fish in a lake. If the number of fish in the lake increased by 15 percent during the last year and 20 percent during the year before that, how many more fish are in the lake currently than in the last two years ago?
Answers
I’m pretty sure the answer should be 1,710 if not i’m sorry
Answer:
1710 fish
Step-by-step explanation:
Let the number of fish in the lake last year be 'x'
The equation becomes-
x + 15x/100=6210 (This is because 15% of x is added in x to become
6210... hope you understand)
x + 15x/100 = 6210
115x/100 = 6210
23x/20 = 6210
x = 6210 * 20/23
x = 270 * 20
x = 5400
Therefore- The number of fish last year = 5400
Now, let the number of fish in the lake 2 years ago be 'y'
The equation becomes-
y + 20y/100 = 5400 (Same logic as last time)
y + 20y/100 = 5400
120y/100 = 5400
24y/20 = 5400
6y/5 = 5400
y = 5400 * 5/6
y = 900 * 5
y = 4500
Therefore- Fish in the lake two years ago = 4500 fish
Difference between current and two years ago = 6210-4500
= 1710 fish
Hope you understood the answer and I hope it helps you :)
