Answer:
[tex]7.21\ units[/tex]
Step-by-step explanation:
Start by giving the points coordinate points assuming the origin is the bottom left:
[tex]A(4,2)\\B(10,6)[/tex]
Apply the formula for the distance between two points:
[tex]d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
[tex]d = \sqrt{(10-4)^2+(6-2)^2}[/tex]
[tex]d = \sqrt{6^2+4^2}[/tex]
[tex]d = \sqrt{36+16}[/tex]
[tex]d = \sqrt{52}[/tex]
[tex]d = 7.21\ units[/tex]
Answer:
7.22 units
Step-by-step explanation:
Using Pythagorean Theorem
AB = √6² + 4²AB = √36 + 16AB = √52AB = 2√13AB = 2 × 3.61AB = 7.22 units2y-6=3y+5
find the value of y
Answer:
[tex]\boxed{\sf{y=-11}}[/tex]Step-by-step explanation:
GIVEN:
To find the value of y, isolate it on one side of the equation.
2y-6-3y+5
Solutions:
First, add by 6 from both sides.
2y-6+6=3y+5+6
Solve.
Add the numbers from left to right.
5+6=11
2y=3y+11
Then, you subtract by 3y from both sides.
2y-3y=3y+11-3y
Solve.
-y=11
Divide by -1 from both sides.
-y/-1=11/-1
Solve.
Divide these numbers goes from left to right.
11/-1=-11
[tex]\Longrightarrow: \boxed{\sf{y=-11}}[/tex]
Therefore, the final answer is y=-11.I hope this helps. Let me know if you have any questions.

.2%
There are 5 numbers and only one of each number.
The probability of landing in 5 would be 1/5
The probability of landing in 2 would be 1/5
The probability of landing on 5 then 2 is 1/5 x 1/5 = 1/25 = 0.04 = 4%

Two angles have measures of (x + 14)º and (3x – 15). What value of x will make the angles congruent?
Answer:
x = 14º 30' OR 14.5º
Step-by-step explanation:
(x + 14)º = (3x – 15)º
3x -x = 14º +15º
2x = 29º
x = 14º 30' OR 14.5º

How many solutions are there to the equation below?
√√√x = 16
Ο Α. 0
OB. 2
C. 1
OD. 4
Answer:
C. 1
Step-by-step explanation:
Given:
[tex]\displaystyle \large{\sqrt{\sqrt{\sqrt{x}}} = 16}[/tex]
The equation can be rewritten as:
[tex]\displaystyle \large{\sqrt[8]{x} = 16}[/tex] via surd property.
Since it’s an even surd, that means there only exists zero-positive numbers for value of x.
To solve this surd equation, simply clear out the surd by powering both sides by 8:
[tex]\displaystyle \large{\left(\sqrt[8]{x}\right )^8=(16)^8}[/tex]
Cancel the surd:
[tex]\displaystyle \large{x=16^8}[/tex]
Now, evaluating 16^8 will give up a million and that’s not necessary because we are finding how many solutions this equation has. Since theee only exists one value of x, which is the solution to this equation. Therefore:

In a batch of 860 calculators, 9 were found to be defective. What is the probability that a calculator chosen at random will be defective? Write the probability as a percent. Round to the nearest tenth of a percent if necessary.
Answer:
Number of calculators n(C)=860
Number of defectives n(D)=9
The probability of a random number being defective=n(D)/n(C)
p=9/860.
converting this to a percentage gives us, 9/860×100%
=90/86
=45/43
=1.0465%
Therefore rounding this number to the nearest tenth gives us 1.0 % since the hundredth digit is 4 which is less than 5.
so, the probability of choosing a random defective calculator is 1.0%

Factor the trinomial 6x² + 5x - 25. Which of the following is a factor?
O (3x + 5)
O (2x - 5)
O (3x - 5)
O (2-25)
Answer:
(3x - 5 )
(2x + 5)
Step-by-step explanation:
f(x) = 6x² + 5x - 25
Let's factor it:-
We need 2 numbers whose product = ( 6*-25) = -150 and whose sum = + 5.
These are 15 and -10. So we write:
f(x) = 6x^2 + 15x - 10x - 25
= (3x - 5)(2x + 5)
= 3x(2x + 5) - 5(2x + 5)
So the factors are (3x - 5) and (2x + 5)

What is the factorization of the polynomial below?

O A. (x + 2)(x+4)
O x6
B. (x + 2)(x+6)
O C. (x + 4)(x+4)
O D. (x+8)(x + 1)
The factorization of the polynomial [tex]x^2 + 6x + 8 is (x + 2)(x + 4)[/tex], which is option A.
To factor the polynomial[tex]x^2 + 6x + 8[/tex], we need to find two numbers whose product is 8 and whose sum is 6, since we're looking for two terms that add up to the middle coefficient of the quadratic expression.
The factors of 8 are ±1, ±2, ±4, and ±8. The pairs of factors that add up to 6 are (2, 4) and (-2, -4). Since the second coefficient is positive, we can select the pair (2, 4), since their sum is positive 6.
Using these factors, we can rewrite the quadratic expression as:
x^2 + 6x + 8 = (x + 2)(x + 4)
We can check our work by expanding the factors using the distributive property:
(x + 2)(x + 4) =[tex]x^2 + 4x + 2x + 8 = x^2 + 6x + 8[/tex]
This confirms that the factorization is correct.(option-a)

9. Arianna has two piles of newspapers
to take to recycling. The first pile
weighs 10 pounds 7 ounces. The
second pile weighs 148 ounces. What
is the total weight of the newspapers?
A. 19 pounds 11 ounces
B. 22 pounds 11 ounces
C. 25 pounds 3 ounces
D. 29 pounds 3 ounces
Answer:
(D) 29 pounds 3 ounces
Step-by-step explanation:
1 pound = 16 ounces
Therefore 10 pounds = 16 * 10 = 160 ounces
160 + 7 = 167 ounces (first pile)
Total Weight of Newspapers = Weight of First Pile + Weight of Second Pile
= 167 + 148 = 315 ounces
As 16 ounces = 1 pound
1 ounce = 1/16 pound
315 ounces = (1/16) * 315 = 19.6875 pounds
1 pound = 16 ounces
0.6875 pounds = 16 * 0.6875 = 11
19 + 11 = 30 pounds, which is close to ans (D)
