Answer:

13.9

Step-by-step explanation:

Use the distance formula:

[tex]d = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2}\\\\d = \sqrt{(7 - (-5))^2 + (-4-3)^2}\\d = \sqrt{(12)^2 + (-7)^2}\\d = \sqrt{144 + 49}\\d = \sqrt{193}\\[/tex]

The square root of 193 rounded to the nearest tenth is 13.9.

Answer:

D.

Step-by-step explanation:

I would have to say D is the best answer since then it's truly based on luck and it's almost as if it's being flipped once

Hillary and her friends could flip a coin twice to fairly decide which activity they will do. If the coin lands on heads one time and tails one time, they will go bowling. If it doesn't, they will go to a movie.

Probability is the ratio that shows the likelihood of an event occurring out of all the other possible events.

Hillary and her friends need to use a fair method to determine which activity to do. For this, the probability should be 1/2. We should observe the given options and find which is the fairer method.

Therefore, Hillary and her friends could flip a coin twice to fairly decide which activity they will do. If the coin lands on heads one time and tails one time, they will go bowling. If it doesn't, they will go to a movie. The correct answer is Option B.

Answer:

1/12 * (-4x+3)

Step-by-step explanation:

1/3x + 1/4 - 2/3x

1/12 * (4x+3-8x)

1/12 * (-4x+3)

Answer/Step-by-step explanation:

a. First, find the value of a.

Sum of the interior angles of a triangle = 180° (triangle sum theorem)

Therefore:

3a + 2a + a = 180°

Add like terms

6a = 180°

6a/6 = 180/6

a = 30

Thus:

a = 30°

2a = 2(30) = 60°

3a = 3(30) = 90°

b. The triangle is an isosceles triangle because it has two sides that are indicated to be equal. This also implies that the angels opposite each of the equal sides are also congruent to each other.

Therefore, sum of the isosceles triangle would be:

2(2x) + 5x = 180°

4x + 5x = 180

9x = 180

9x/9 = 180/9

x = 20

Thus:

2x = 2(20) = 40

5x = 5(20) = 100

I just want to mention that the question is wrongly written!

it's meant to be  x² − 10x − 11 = 0 and not x2 − 10x − 11 = 0

and so the other equations!

Answer:

The answer is B: (x − 5)² = 36

Step-by-step explanation:

by solving the equations using the quadratic formula we found:

the solutions for x² − 10x − 11 = 0 | x = 11, -1

the solutions for A | x = 16, 4

the solutions for B | x = 11, -1

the solutions for C | x = [tex]\sqrt{21} +5[/tex], [tex]-\sqrt{21}+5[/tex]

the solutions for D | x = [tex]\sqrt{21}+10, -\sqrt{21}+10[/tex]

the given equation: x² − 10x − 11 = 0 and the equation B: (x − 5)² = 36 have the same solutions

Therfore B is the correct answer

From the question,

Rohan bought an almirah for =Rs.13600= cost price

Transportation cost =Rs.400

The total cost price of almirah =Rs.(13600+400)

The total cost price of almirah =Rs.(13600+400)=Rs.14000

He sold it for =Rs.16800= selling price

By comparing SP and CP=SP>CP, so there is a gain

Gain=SP−CP

=16800−14000

=Rs.2800

Gain %={(gain/CP)×100}

={(2800/14000)×100}

={2800/140}

=20%

Answer:

[tex]\boxed {\boxed {\sf 3 \ pounds \ of \$4 \ candy}}[/tex]

[tex]\boxed {\boxed {\sf 2.5 \ pounds \ of \$3.50 \ candy}}[/tex]

Step-by-step explanation:

Let's create a system of equation. First, define the variables. One type of candy is x and the other is y.

Now, create 2 equations, one for the weight and one for the price.

[tex]x+y=5.5[/tex]

[tex]4x+3.5y=20.75[/tex]

The first equation represents the mixture of both types of candy that weighs 5.5 pounds. The second represents the prices of the candy and the mixture.

Next. solve for the variables using substitution. Isolate a variable in the first equation. Let's isolate y by subtracting x.

[tex]x-x+y=5.5-x\\y= 5.5-x[/tex]

Now, we know what y is equal to, so we can substitute it into the second equation.

[tex]4x+ 3.5 (5.5-x)= 20.75[/tex]

Distribute the 3.5. Multiply each term by 3.5

[tex]4x+(3.5*5.5)+(3.5*-x)[/tex]

[tex]4x+19.25-3.5x= 20.75[/tex]

Combine like terms on the right side.

[tex]0.5x+19.25=20.75[/tex]

Subtract 19.25 from both sides of the equation to isolate the variable.

[tex]0.5x+19.25-19.25=20.75-19.25[/tex]

[tex]0.5x= 1.5[/tex]

Divide both sides by 0.5.

[tex]\frac {0.5x}{0.5}= \frac{1.5}{0.5}\\x=3[/tex]

Now we can substitute x back into the first equation and solve for y.

[tex]x+y=5.5\\3+y=5.5[/tex]

Subtract 3 from both sides to isolate the variable.

[tex]3-3+y=5.5-3\\y=2.5[/tex]

There was 3 pounds of the $4 candy and 2.5 pounds of the $3.50 candy.

[tex]\large\boxed{(5,8) \text{ and } (1.2, -2.78)}}[/tex]

We are given the equation:

x² - 2y = 7

To verify if each ordered pair is apart of the function, we can plug in their respective x and y values:

1. (5)² - 2(8) = 7

25 - 16 = 9 ≠ 7. This is NOT correct.

2. (-1)² - 2(-3) = 7

1 + 6 = 7. This is correct.

3. (-4)² - 2(-11.5) = 7

16 + 23 = 39 ≠ 7. This is NOT correct.

4. (1.2)² - 2(-2.78) = 7

1.44 +5.56 = 7. This is correct.

Thus, only 1 and 4 are the correct answers.

No yes no yes
