Answer:
1 ,2, and 3
Step-by-step explanation:
Jorge's weight percent decrease is (190-180)÷190, or amount of change/original amount. Simplified, 10÷190=5.2637157894...%, approximately equal to 5%. The first option is correct. Marie's percent decrease is (175-150)÷175. Simplified, that is 25÷175=14.2857142857...%, which is about 14%. The second option is correct. Clearly, we can tell that Marie had the greater percent change, about 14% to about 5%. Also clearly, Jorge did not have the greater percent change, so we can tell Option 4 is wrong. We already know that Jorge's change is about 5% and Marie's is about 14%, so they can't be about 0.5% or about 1.4%. Options 5 and 6 are incorrect. The correct answers are 1, 2, and 3.
Hope this helps you!

Mario made 2 goals for every 5 shots on goal. What is the probability that Mario would make 2 goals on two shots?
Answer:
16%
Step-by-step explanation:
To calculate this we first need to calculate the probability of Mario scoring for every individual shot that he takes. Since he makes 2 goals for every 5 shots on average, we simply divide these numbers to get the probability of a goal per shot.
2 / 5 = 0.4 ...multiply by 100 to get percentage value
0.40 * 100 = 40%
We see that the probability of scoring a goal per shot is 40%. Now we need to multiply this probability twice to get the probability of scoring 2 consecutive goals in two shots.
0.40 * 0.40 = 0.16 ... multiply by 100 to get percentage value
0.16 * 100 = 16%
Answer:
16%
Step-by-step explanation:
I know that 2/5 = 0.4 or 40%
and 0.4 x 0.4 = 0.16
or 16%
basically what the other one said, without words

what fraction is equivalent to 3/9
Answer:
the simplified version of 3/9 would be 1/3 but other equivalent fractions of 3/9 would include but are not exclusive to: 2/6, 4/12, 5/15, and etc.
The required fraction 3/9 is equivalent to 1/3.
Given that the fraction is 3/9.
Equivalent fractions are the fractions are same at their simplest form.
Let a/b be the fraction, then the equivalent fractions are
2a/2b, 3a/3b, 4a/4b, 5a/5b, etc
To find an equivalent fraction, we simplify the given fraction by dividing both the numerator and denominator by their greatest common divisor (GCD).
In this case, the GCD of 3 and 9 is 3.
Dividing both 3 and 9 by 3, we get:
3 ÷ 3 = 1
9 ÷ 3 = 3
Therefore, the fraction 3/9 simplifies to 1/3, which is an equivalent fraction.

A certain model car has a keypad with 5 numbers on the door. To open the door, 5 numbers must be entered in the correct
order and no number can be used more than once. What is the probability that someone could guess the correct code?
OA. Ito
OB.
OC.
OD.
Answer: A. [tex]\dfrac{1}{120}[/tex]
Step-by-step explanation:
Total digits on keypad = 5
According to permutation,
If repetition of digits is not allowed then the number of 5-digits passwords can be formed = 5!
= 5 x 4 x 3 x 2 x 1 [n!=n x (n-1) x (n-2)x ... x 1]
=120
The probability that someone guesses the correct code = [tex]\dfrac{\text{Number of correct codes}}{\text{Total possible codes}}[/tex]
[tex]=\dfrac{1}{120}[/tex]
Hence, the correct option is A.
Explain two different ways to find a new value after an original value is increased by 30%.
Answer:
Frequently, we know the new amount and the percent change and need to know the original amount. We found that a $600 TV on sale for 30% off, cost $420 on sale. We might think, that to find the original cost of the TV that has a sale price of $420 after a sale of 30% off, we could just take 30% of the $420 cost and add it back to the $420 to find the original cost.
30% of $420 is 0.30($420) = $126 and $420 + $126 = $546.
Or, 130% of $420 is 1.3($420) = $546.
Notice that this is not the $600 original list price with which we started.

The length of a rectangle is 3 inches less than three times its width. The perimeter of the rectangle is 34 inches. Find the dimensions of the rectangle
Given:
The length of a rectangle is 3 inches less than three times its width.
The perimeter of the rectangle is 34 inches.
To find:
The dimensions of the rectangle.
Solution:
Let x be the width of the rectangle. Then, the length of a rectangle is 3 inches less than three times its width.
Length of the rectangle = 3x-3
Now, perimeter of the rectangle is
[tex]Perimeter=2(Length + Width)[/tex]
[tex]Perimeter=2(3x-3+x)[/tex]
The perimeter of the rectangle is 34 inches.
[tex]34=2(4x-3)[/tex]
[tex]34=8x-6[/tex]
[tex]34+6=8x[/tex]
[tex]40=8x[/tex]
Divide both sides by 8.
[tex]\dfrac{40}{8}=x[/tex]
[tex]5=x[/tex]
The value of x is 5. So, width of the rectangle is 5 inches.
[tex]Length=3x-3[/tex]
[tex]Length=3(5)-3[/tex]
[tex]Length=15-3[/tex]
[tex]Length=12[/tex]
Therefore, the length of the rectangle is 12 inches and the width of the rectangle is 5 inches.

Answer:
x = - 3 and x = 1
Step-by-step explanation:
4x - 2 - 2x = x - 5, that is
2x - 2 = x - 5 ( subtract x from both sides )
x - 2 = - 5 ( add 2 to both sides )
x = - 3
----------------------------------------
- (x + 3) = 2x - 6 ← distribute left side
- x - 3 = 2x - 6 ( subtract 2x from both sides )
- 3x - 3 = - 6 ( add 3 to both sides )
- 3x = - 3 ( divide both sides by - 3 )
x = 1

If the expression
(3v+7) - (8v+6)
needs to be equivalent to
(-5+n)
What is the value of n?
Answer:
n = 1
Step-by-step explanation:
So the first step is to simplify the top equation:
(3v + 7) - (8v + 6)
distribute the negative sign to get rid of the second parentheses:
3v + 7 - 8v - 6
now, combine like terms
-5v + 1
Since it says it needs to be equivalent to (-5v + n), n is 1

Select the solution(s) of log2x=1−log(x+4).
Step-by-step explanation:
log2x = 1 - log(x+4)
log2x = log10 - log(x+4)
log2x = log[10/(x+4)]
2x = 10/(x+4)
2x(x+4) = 10
2x² + 8x - 10 = 0
÷2 both sides of equation
x² + 4x - 5 = 0
(x+5)(x-1) = 0
x = -5, 1
x isn't be -5 because logA, A need to be > 0
So, x value is 1
