Which set of values could be the side lengths of a 30-60-90 triangle?
Answer:
A
Step-by-step explanation:
I think you are in geometry I learned this a little back...
It's hard to explain but basically one side is just (n) another is (n(square root sign))and another is (2n.)
So the answer Is a because in this case (n) is 4

Answer:
x=−12
Step-by-step explanation:
Let's solve your equation step-by-step.
x=23−25−10
Step 1: Simplify both sides of the equation.
x=23−25−10
x=23+−25+−10
x=(23+−25+−10)(Combine Like Terms)
x=−12
Can someone tell me about proportions??? PLEASE I NEED HELP ASAP
Answer: A ratio is one thing or value compared with or related to another thing or value; it is just a statement or an expression, and can only perhaps be simplified or reduced. On the other hand, a proportion is two ratios which have been set equal to each other; a proportion is an equation that can be solved.

A coin is flipped 18 times. Three of the times the coin landed on heads and the rest of the times tails. What is the difference between the THEORETICAL and EXPERIMENTAL probability of landing on heads? *
Answer:
the experimental probability is based on the results of the experiment which yielded heads 1 out of 6 times; in theory, the results of flipping a coin and landing on heads would be 1 out of 2

1. Write in interval notation: 2|3-4x|+5>4
2. Write in set builder notation: |2-3x|=|x-3|
Answer:
See bolded below
Step-by-step explanation:
1. First solve the inequality:
2|3-4x|+5>4 [subtract 5 from both sides]
2|3-4x| > - 1 [divide both sides by 2]
|3-4x| > - 1/2
Since all absolute values are always greater than or equal to 0, the solution would be: All Solutions. Respectively in interval notation we have (- ∞, ∞)
2. Start by solving the equation:
|2-3x|=|x-3|,
2-3x = x-3, 2-3x = -(x - 3)
x = 1.25, x = -0.5
In set builder notation: { x | x ∈ {1.25, -0.5} }
A man wants to enclose a rectangular garden adjacent to a river. The length of the rectangle is two times the width. How many linear feet of the fence must he buy if he does not need fencing along the river and the perimeter of the rectangle is 240 feet?
Answer:
200, 160
Step-by-step explanation:
if perimeter is 240 it means sides are 40 by 80.
if he does not need to place fencing on one side, they remove one 80 or 40,
40+80+80=160 or 40+40+80=200
Boom Awser
Answer:
200 160
Step-by-step explanation:
if the perimeter is 240, the length is 80 and width is 40.
40+80+80=200
80+40+40=160
A store pays $22 for a surfboard. The store marks up the price by 37%. What is the amount of the mark-up?
Answer:
$8.14
Step-by-step explanation:
Given data
Cost of surfboard= $22
Mark up = 37%
Required
The amount of the markup
let us find 37% of $22
=37/100*22
= 0.37*22
= $8.14
Hence the amount of the markup is $8.14

y- 4/5=1
what does y equal to?
Answer:
y=1.8
Step-by-step explanation:
first change the fraction into a decimal.
4/5 =0.8
plus the 0.8 to both sides
y=1.8
Answer:
[tex]y - \frac{4}{5} + \frac{4}{5} = 1 + \frac{4}{5} \\ y = \frac{5 + 4}{5 } \\ y = \frac{9}{5} [/tex]

Brooke multiplied 3 and 9 and got 17 Brooke knows her answer is wrong because she know it should be approximately
Answer:
Kindly check explanation
Step-by-step explanation:
If Brooke multiplied 3 by 9 and obtained 17 ; then Brooke is definitely wrong
3 * 9 = exactly 27
However, for approximation sake ;
We could round 9 to 10 ; and multiply 10 by 3
10 * 3 = 30 ; this gives an approximate solution for the multiplication problem ;
3 * 9 = exactly 27 or approximately 30

I think it’s c?
Answer:
B. f(x) = -x + 2
Step-by-step explanation:
First, you find the point on the y-axis which is (0,2) in this problem.
This will be your b in y = mx+ b
Then, you'll find how many blocks you are moving or rise over run. Which is -1/1 or -1.
This will be your m in y = mx + b
But we don't write the 1 so it will just be -x
Now add all your numbers in the standered form (y = mx + b) to get y = -x + 2 or f(x) = -x + 2
Oceanside bike rental shop charges seventeen dollars plus seven dollars an hour for renting a bike. Jason paid eighty dollars to rent a bike. How many hours did he have to pay to have the bike checked out?
Answer:This is a linear equation.
y = mx+b
y is the total cost.
The slope m is the rate: that's 9 dollars per hour.
x is the number of hours.
b is the initial value: that's 16 dollars.
y = 9x+16
The problem states that the cost was 79 dollars.
Substitute that for y and solve for x.
79 = 9x+16
63 = 9x
x = 7 hour
Step-by-step explanation:
Answer:
9
Step-by-step explanation:
80-17=63
63/7 = 9
7 times 9 = 63
