Answer:

3 units bruh

Step-by-step explanation:

The length of the segment AB is 3 unit.

According to a property of circles, when a line passes through the center of a circle and is perpendicular to a chord, it divides the chord into two equal parts, essentially bisecting it.

We have,

Chord AC = 6 units

Now, we know that when the diameter is perpendicular to the chord bisect the chord and arc

Then, AB = CB

Thus, the length of the segment AB will be:

AC = AB + CB

6 = x + x

2x = 6

x= 3

AB = 3 unit

We have 2 x 3 + 3 x (-3) + 5 = c;

Then, 6 - 9 + 5 = c;

- 4 + 5 = c;

1 = c;

Finally, c = 1.

The correct answer is:

(x,y) = (6,2)

Option A would be the correct one.

Answer:

The answer is (6, 2).

Step-by-step explanation:

This is a system of equations so we have to replace one equation in the other one, this is:

[tex]2x-y=10[/tex] Eq. 1

[tex]y=-\frac{1}{2}x+5[/tex] Eq. 2

Replacing the Eq. 2 in the Eq. 1, we have:

[tex]2x-(-\frac{1}{2}x+5)=10[/tex]

[tex]2x+\frac{1}{2}x-5=10[/tex]

[tex]2.5x=10+5[/tex]

[tex]x=\frac{15}{2.5}[/tex]

[tex]x=6[/tex]

Now we have that x=6, we can replace it in the Eq. 2:

[tex]y=-\frac{1}{2} *6+5\\y=-3+5\\y=2[/tex]

Now y=2

From the above we have that the answer is (6, 2) expressed in Cartesian coordinates.

Answer:

Correct cost for the cell phone monthly plan = 54.2$

Explanation:

Price for monthly plan = 58.95$

Discount = 4.75 $

New cost found out by Sam = 11.45$

Discount considered by Sam = 58.95 - 11.45 = 47.5$

So, Instead of considering discount amount of 4.75$ Sam accidentally considered 47.5$, so he got 11.45$ as new cost for the cell phone plan.

Actual cost = 58.95 - 4.75 = 54.2$

Correct cost for the cell phone monthly plan = 54.2$

The previous year's salary is x.

This year's salary is x + 3000.

12% of this year's salary is $4200.

12% * (x + 3000) = 4200

0.12(x + 3000) = 4200

x + 3000 = 35,000

x = 32,000

Answer: Her salary in the previous year was $32,000.

The answer is c the number of games that Ella played, because it says she got 16 points per game.

The answer you are looking for is 1/3.

First, you must look at the denominators of each fraction, to see if you can simply divide straight across. In this case, you cannot, which means you must multiply by the reciprocal or "flipped" number. Generally when you multiply by the reciprocal, you flip the number with the smaller denominator to multiply.

So, you have 4/3 * 3/12. You then multiply straight across (4 * 3)/(3 * 12), to get an answer of 12/36, which simplified (divided by 3/3) gives you a final answer of 1/3.

Answer:

A) She must have used 20% from the $40 instead of the unknown price.

B) No, because: see below explanation.

Step-by-step explanation:

X is the original price.

If $40 is 80% of x, to find 1% of the price, divide $40 by 80.

You will get $0.50 for 1%.

To find the full amount, just multiply that by 100.

0.50*100= 50.

Total: $50.

Hope this helped!

Jane's friend calculated the original price by dividing $40 by 80 and multiplying by 100. However, they made a mistake in their calculations. The correct original price before the 20% discount should be $50.

A) It seems that Jane's friend arrived at $48 by considering $40 as 80% of the original price. Since Jane received a 20% discount, it means she paid 80% of the original price. Thus, her friend might have calculated by dividing $40 by 80 and then multiplying by 100 to find the original price.

B) However, her friend's calculation is incorrect. If we indeed divide $40 by 80 and multiply by 100, we get $50, not $48. This means the original price of the item is $50.

To further illustrate this, let's consider the original price to be 'x'. If Jane received a 20% discount, she paid only 80% of 'x'. So, 0.8x = $40. Solving for 'x', we get x = $40 / 0.8 = $50.

Now, the number of participants who chose fishing= 29

So,

The percent of survey participants who chose fishing= (the number of participants who chose fishing/the number of participants who completed survey)x100

The percent of survey participants who chose fishing= 29/47x100

The percent of survey participants who chose fishing= 61.70%

Answer:

Step-by-step explanation:  29/18+29 x 100

The coefficient in the expression x/3 + 7 is 1/3, as the variable x is being divided by 3, indicating an implied multiplication of 1/3 times x.

In the expression x/3 + 7, the term x/3 has a coefficient which is the number multiplying the variable x. In this case, the coefficient is 1/3 because x can be thought of as 1x and it is being divided by 3, so the coefficient for x is actually 1/3. The number 7 in the expression is a constant and not a coefficient because it does not multiply a variable.

To find a coefficient, you generally look for the number that is directly multiplied by the variable. In the given expression, since there is a division by 3, we treat 1/3 as the coefficient, which is an implied multiplication by x. Therefore, the coefficient of the variable x in the expression x/3 + 7 is 1/3.

You bought 555 apples and 444 oranges and your friend bought 555 apples and 555 oranges. He bought 555-444=111 oranges more than you bought.

You paid $10, he paid $11, then he paid $1 more than you paid.

This means that 111 oranges cost $1.

Thus, 444 oranges cost $4 and 555 apples cost $10-$4=$6.

1. If 111 oranges cost $1, then 1 orange cost [tex]\$\dfrac{1}{111} .[/tex]

2. If 555 apples cost $6, then 1 apple cost [tex]\$\dfrac{6}{555}=\dfrac{2}{185}.[/tex]

Answer:

Each apple costs $1.20 and each orange costs $1.

Step-by-step explanation:

Let x represent the number of apples and y represent the number of oranges.

For the fruit you bought, 5 apples and 4 oranges, we have 5x+4y.  This costs $10.  This gives us the equation

5x+4y = 10

For the fruit your friend bought, 5 apples and 5 oranges, we have 5x+5y.  This costs $11.  This gives us the equation

5x+5y = 11

Together we have the system

[tex]\left \{ {{5x+4y=10} \atop {5x+5y=11}} \right.[/tex]

We will eliminate x by subtracting the bottom equation from the top:

[tex]\left \{ {{5x+4y=10} \atop {-(5x+5y=11)}} \right. \\\\-1y = -1[/tex]

Divide both sides by -1:

-1y/-1 = -1/-1

y = 1

Each orange costs $1.

Substitute this into the first equation:

5x+4(1) = 10

5x+4 = 10

Subtract 4 from each side:

5x+4-4 = 10-4

5x = 6

Divide both sides by 5:

5x/5 = 6/5

x = 1.2

Each apple costs $1.20.

Answer:

That 9 is divisible by 3.

Step-by-step explanation:

For this case we have the following statement:

"All odd numbers are divisible by 3"

The options given are the following:

a) 7 is odd but not divisible by 3, therefore it is a counterexample of the given statement

b) 9 is odd and is divisible by 3, therefore it is not counter-example

c) 8 is an even number, it is not a counter-example

d) 3 is odd and affirms the given statement.

Therefore, the correct answer is option A.

Answer:

Option A

the number that would have rounded to 800,000 would have been 10,000 so it would have been 70,000

In step 2, multiply what is inside the parentheses by 7 (distributive property):

7 * x = 7x

7 * 3 = 21

In step 3, subtract -7x on both sides of the equation. (Property of subtraction of equality)

Then -7x + 4x = -3x

7x-7x + 21 = 21

In step 4, both sides of the equation are divided by -3.

So (owned by the equality division)

-3x / -3 = x

-21 / -3 = 7

Remember that the division of equal signs results in a positive number.

4x = 7(x-3)                  Given equation

4x = 7x - 21               7 is distributed inside the parenthesis . So the property used here

                                     is distributive property                

-3x = -21                    7x is subtracted from both sides. 4x-7x is -3x. So the property used

                                   here is subtraction property of equality.

x = 7                         -3 is divided on both sides.  -21/3 is 7. So the property used

                                   here is division property of equality.

Answer:

4.28 $

Step-by-step explanation:

Given that a store sold 55 pairs of shoes for 85.60 each.

Sale proceeds = 55(85.60) = 428 dollars.

Later on 100 scafs were purchased.  For that the price was 428 dollars.

The proceeds of 428 dollars  were spent buying 100 scarves.

i.e. price of 100 scarves = 428 dollars

Hence price of 1 scarve = 428/100 = 4.28 $

Price of 1 scarve is 4.28 dollars is the answer

The zeros of the function f(x) = x(x -4)((x + 8) is 0, 4 and -8. The correct options for the zeros of the function are: A, C, D

The zeros of a function are the values of the variables x for which f(x) is said to be equal to zero. From the given function, we will replace the value of x with zero and solve the function, the variable we get at the end of the solution are the zeros of the given function.

SO,

f(x) = x (x - 4)(x + 8)

Now, the zeros of the function can be computed as:

f(0) = 0 (0 - 4)(0 + 8)

f(0) = 0 ( -4) (8)

∴

f(0) = x  or    x - 4    or    x + 8

f(0) = x   or    x = 4   or    x = -8
