Can Someone Tell Me Were I Went Wrong?A Different Camera Is Selling For $7.50 Off The Regular Price.

Answers

Answer 1
I think the answer is C)!
$50.00
Answer 2

Answer:

C) $50.00

Step-by-step explanation:

$7.50 is the 15% discount

1% of the original price would be ($7.50 / 15)=0.50

100% of the original price would be 100 x 0.50 =  $50.00

Answers

Answer:

v=-12

Step-by-step explanation:

-8=v+4

-4     -4

-12=v

Answer:

v = -12

Step-by-step explanation:

We have the equation v + 4 = -8

Subtract 4 from both sides.

v + 4 - 4 = -8 - 4

+4 and -4 cancel one another out.

We get v = -12.

Reena bought a mobile phone for 16,240 that included a GST of 12%. Find the price of the mobile phone before the GST was added.​

Person who answers will be marked brainliest

Answers

Answer: 14500

Step-by-step explanation:

Let the price of the mobile phone before the GST was added be represented by x.

Therefore,

x + (12% × x) = 16240

x + 0.12x = 16240

1.12x = 16240

x = 16240/1.12

x = 14500

The price of the mobile phone before the GST was added was 14500

Step-by-step explanation:

A factory makes 450 pies every day.
The pies are chicken pies or steak pies.
Each day Milo takes a sample of 15 pies to check.
The proportion of the pies in his sample that are chicken is the same as the proportion
of the pies made that day that are chicken.
On Monday Milo calculated that he needed exactly 4 chicken pies in his sample.
Work out the total number of chicken pies that were made on Monday.​

Answers

Step by step:

Each day it takes a sample of 15 pies - on Monday he needed 4:

4/15 = x/450 (450 being the total for each day)

4 x 450 = 1800
1800 divided by 15 = 120

120 is the amount of pies that were made on Monday

A quadratic equation has a
discriminant equal to 5. What
does this tell you about the
solution(s) to the equation?

Answers

Answer:

[tex]\boxed {\boxed {\sf 2 \ real \ solutions }}[/tex]

Step-by-step explanation:

The quadratic formula is:

[tex]{x = \frac{{ - b \pm \sqrt {b^2 - 4ac} }}{{2a}}}[/tex]

The discriminant of a quadratic is just the expression under the square root, or [tex]b^2-4ac[/tex]. This can tell us the number of solutions a quadratic has.

If the discriminant is:

Positive = 2 real solutions Equal to Zero = 1 real double/repeated solution Negative = 0 real solutions, but 2 imaginary solutions

Our quadratic equation has a discriminant of 5, which is positive. Therefore, it has 2 real solutions.

graph the solution on the number line x+8 ≥ 5

Answers

Answer:

For the inequality to be true, both factors must have the same sign or one factor must be 0. The zeroes occur at x = − 2 , x = 5 . Thus, our intervals will be ( − ∞ , − 2 ] , [ − 2 , 5 ] , [ 5 , ∞ ) Take a sample point from each. A sample point of − 3 for the first interval yields ( − 3 + 2 ) ( − 3 − 5 ) = ( − 1 ) ( − 8 ) = 8 , so the first interval satisfies the inequality. Choosing a sample point of x = 0 for the second interval, we receive ( 2 ) ( − 5 ) = − 10 , so this interval will not satisfy the equality. A sample point of x = 6 for the third interval gives us ( 8 ) ( 1 ) = 8 , so the third interval satisfies. Thus, the domain that satisfies the inequality is ( ∞ , − 2 ] & [ 5 , ∞ ) On the number line , you would draw and fill in a circle above -2, and draw an arrow from that point to the left. You would then draw and fill in a circle above 5, and provide a similar arrow to the right (i.e. towards positive infinity). We fill in these circles because the intervals are closed at these points, i.e. these points satisfy the inequality. If we instead had ( x + 2 ) ( x − 5 ) > 0 , the circles would be empty because those points would not satisfy.

Calculate the value of x

Answers

Answer:

x = 8

Step-by-step explanation:

The perimeter (P) is calculated as

P = 2(l + b) ← l is length and b is breadth

Here l = 12 and b = x , P = 40, then

2(12 + x) = 40 ( divide both sides by 2 )

12 + x = 20 ( subtract 12 from both sides )

x = 8

Write the equation of the line that goes through (9,-4) and is perpendicular to the line
y = -3x – 8

Answers

Answer: y = (1/3)*x - 7

Step-by-step explanation:

When we have a line:

y = a*x + b

A perpendicular line to this one needs to have a slope s equal to:

s = -(1/a)

Then any line written as:

y = -(1/a)*x + c

is perpendicular to the lines of the form "y = a*x + b"

Then if we have the line:

y = -3*x - 8

The family of perpendicular lines to this one is:

y = -(1/-3)*x + c

y = (1/3)*x + c

where c can be any real number.

Now we also want that this line passes through the point (9, -4)

Then we need to replace x by 9, and y by -4

-4 = (1/3)*9 + c

Now we can solve this for c.

-4 = 9/3 + c

-4 = 3 + c

-4 - 3 = c

-7 = c

Then the line that is perpendicular to the line y = -3x – 8 and that goes through (9, -4) is:

y = (1/3)*x - 7
