Find the distance between (3,4) and (4,-6).
Answer:
The answer is
[tex] \sqrt{101} [/tex]Step-by-step explanation:
The distance between two points can be found by using the formula
[tex]d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\[/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(3,4) and (4,-6)
The distance between them is
[tex]d = \sqrt{ ({3 - 4})^{2} + ({4 + 6})^{2} } \\ = \sqrt{ ({ - 1})^{2} + {10}^{2} } \\ = \sqrt{1 + 100 } \: \: \: \: \: \: \: \: \: \\ = \sqrt{101} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: [/tex]
We have the final answer as
[tex] \sqrt{101} [/tex]

1.45 rounded to the nearest hundredth
Answer:
1.45
Step-by-step explanation:
1.45 is already rounded to the nearest hundredth..
Answer:
1.45 (no need to round)
Step-by-step explanation:
When looking at this question we can clearly see that there are only 2 numbers behind the decimal.
We know that the number closet to the decimal is the tenths place.
And that the number second closet to the decimal is the hundredths place.
And that the number third closet to the decimal is the thousandths place.
Since there is no thousandths place we can't round the 5 up.
Which is why your answer is 1.45
When you roll two number cubes, what are the odds, in simplest form, in favor of getting two numbers less than 3?
A• 1:8
B• 8:1
C• 1:9
D• 9:1
(Worth 30+ Points)
Answer:
c
Step-by-step explanation:
If two number cubes are rolled, the odds in favor of getting two numbers less than 3 is 1 : 9.
What is the probability?Probability determines the odd that an event would happen. The odd the event occurs is 1 and the odd that the event does not occur is 0.
Odds in favor of getting two numbers less than 3 = (numbers less than 3 / total numbers) x (numbers less than 3 / total numbers)
2/6 x 2/6 = 1/9

Answer:
54w-9
Step-by-step explanation:
the box to the right is -1 because you are multiplying 6w-1 by 9 (the box next to the blank one on the bottom). the other blank box below the 6w is going to be 54w since you multiply 6w and 9 to get that. therefore, 9(6w-1) is 54w-9.

An irrational number between 2 and 2.5
Answer:
Irrational number between 2 and 2.5 = √2*2.5 = √5
Step-by-step explanation:
2 < √5 < 2.5
We know that √5 is an irrational number.
So, √5 is the required irrational number between 2 and 2.5.
2cy + 8m = 2f solve for c
Answer:
c=(f-4m)/2y

19/20=3p/18
Answer:
p=5.7
Step-by-step explanation:
Cross multiply.
Answer:
p = 5.7
Step-by-step explanation:
Given
[tex]\frac{19}{20}[/tex] = [tex]\frac{3p}{18}[/tex] ( cross- multiply )
60p = 19 × 18 = 342 ( divide both sides by 60 )
p = [tex]\frac{342}{60}[/tex] = [tex]\frac{57}{10}[/tex] = 5.7
Noah is buying a pair of jeans and using a coupon for 10%off. The total price is $56.70 which includes $2.70 in sales tax. Noah’s purchase can be modelled by the equation
x-0.1x+2.70=56.70
what does the solution to the equation mean in this situation?
How can you verify that 70 is not a solution but 60 is the solution?
Answer:
See below.
Step-by-step explanation:
So, we know that Noah's purchase can be modeled by the equation:
[tex]x-0.1x+2.70=56.70[/tex]
Part 1)
The solution to the equation will be the value of x.
In this case, x will represent the original price of the jeans.
We know that Noah has a coupon for 10% off the original price of the jeans.
So, 0.1x will represent how much of the original price Noah gets a a discount on.
Therefore, (x - 0.1x) represents the total cost of the jeans after the coupon.
So, x is our original price of the jeans.
Part 2)
To verify that 70 is not a solution, we can simply substitute 70 for x and check whether or not the equation is true. So:
[tex](70)-0.1(70)+2.7\stackrel{?}{=}56.70[/tex]
Multiply:
[tex]70-7+2.7\stackrel{?}{=}56.7[/tex]
Subtract:
[tex]63+2.7\stackrel{?}{=}56.7[/tex]
Add:
[tex]65.7\neq56.7[/tex]
However, we can verify that 60 is the solution by substituting. So, substitute 60 for every x:
[tex](60)-0.1(60)+2.7\stackrel{?}{=}5.7[/tex]
Multiply:
[tex]60-6+2.7\stackrel{?}{=}56.7[/tex]
Subtract:
[tex]54+2.7\stackrel{?}{=}56.7[/tex]
Add:
[tex]56.7\stackrel{\checkmark}{=}56.7[/tex]
So, 60 is indeed the solution and is the value of x.
So, this means that $60 was the original price of the jeans.
Answer:
$60

X=-4 or X-4
X=-2 or X= 2
X=2
X=4
Answer:
X = - 2 or X = 2
Step-by-step explanation:
*completing the square*
X^2 - 4 = 0
X^2 = 4
X = +-√4
x = +-2
x= -2, 2
*factoring*
X^2 - 4 = 0
(x-2)(x+2) = 0
|. |
x = 2, x = -2
________________________________
(x-2)(x+2) = x(x+2) - 2(x+2) = x^2 + 2x - 2x - 4 = x^2-4
