What is the new price of s shirt that is on sale for 50% off and has an original price of $50?

Answers

50%=1/2 or 1 half. 50/2=$25

Final answer:

To calculate the new price of the shirt on a 50% sale off its original price of $50, divide the original price by 2, resulting in a new price of $25.

Explanation:

The question asks us to calculate the new price of a shirt that is on sale with a 50% discount from its original price of $50. To find the new price, you simply need to reduce the original price by the percentage of the discount. Since a 50% discount cuts the price in half, you divide the original price by 2.

Calculation:

Original price of the shirt: $50

Discount: 50% of $50 = $50 / 2 = $25

New price after discount: $50 - $25 = $25

Therefore, the new price of the shirt after a 50% discount is $25.

What is the slope of a line that is perpendicular to the line y = 8x + 5?

Answers

perpendicular lines, slope is opposite and reciprocal
y = 8x + 5 has slope = 8
so perpendicular line slope = -1/8

answer
-1/8

Answer: [tex]\dfrac{1}{8}[/tex]

Step-by-step explanation:

The given equation of a line : [tex]y = 8x + 5[/tex]

We know that general Slope-intercept form of equation is given by :-

[tex]y=mx+c[/tex], where m is the slope of the line.

When we compare the given equation the general slope intercept form of equation , we get

Slope of line = 8

We know that the product of slopes of two perpendicular line is -1.

Let m be the slope of line that is perpendicular to the line [tex]y = 8x + 5[/tex], then we have

[tex]-8\times m=-1\\\\\Rightarrow\ m=\dfrac{1}{8}[/tex]

how do you do 36-7p=-7(p-5)

Answers

First, distribute the negative seven to the p and negative five in the parentheses. it should look like 36 - 7p = -7p + 35.

Next, add seven p to both sides and it cancels out. 36 -7p = -7p + 35.
+7p= +7p
Then minus thirty five on both sides. You get an inconclusive answer of 1=0

Final answer:

equation 36-7p=-7(p-5) simplifies to 36=35 after distributing and cancelling variables which results in an inconsistency. Therefore, this equation has no solutions.

Explanation:

The question involves working with linear equations. From the equation, 36-7p=-7(p-5), we will aim to isolate the variable, 'p'.

In this equation, start by distributing the -7 into the bracket. So, -7(p-5) becomes: -7*p + 7*5, which simplifies to: -7p + 35. Now, your equation should look like: 36 - 7p = -7p + 35.Next, let's cancel out -7p from one side by adding 7p to both sides. You get: 36 = 35.This is an inconsistency because 36 is not equal to 35. Therefore, this equation has no solution.

Simplifly by using the distributive property 4r+3(r-2)

Answers

7r-6 if you simplify that's the answer.

4r + 3(r - 2)

In order to distribute this, we multiply 3 to r AND -2 each

After using the distributive property, we get the following

3(r - 2) = 3r - 6

Now, let's go back to the whole equation

Liam's bookstore sold 40 notebooks and 20 newspapers for a total of $130. A day later, the bookstore sold 8 notebooks and 4 newspapers at the same prices, for a total of $28. How much does a notebook and a newspaper cost at Liam's bookstore?

Answers

The total sales will be calculated by adding up the revenue from the selling of the notebooks and that of the newspaper. For representation, we let x be the price of each of the notebook and y be the price of each of the newspaper. The equation that allows us to solve this item are,

40x + 20y = 130
and 8x + 4y = 28

With this, if we divide the left hand side by the left hand side of the equation number 2, we have 5. However, 130 divided 28 is not 5 but 4.64. Hence, the system does not have any solution.

Let us say that:

X = price of each notebook

Y = price of each newspaper

So from the problem statement we can create the following equations:

40 X + 20 Y = 130 --> eqtn 1

8 X + 4 Y = 28 --> eqtn 2

Divide both equations by the lowest coefficient to simplify:

Divide eqtn 1 by 20 => 2 X + Y = 6.5

Divide eqtn 2 by 4=> 2 X + Y = 7

So we can see that although both equations has equal left side, the right side do not match. Hence this problem is impossible to solve.

-> The given information describes an impossible situation.

How do I write 6 x 3/20 as a fraction in simplest form?

Answers

first, you need to turn it into a fraction by doing the multiplication. 6/1 × 3/20 which is 18/20. then you simplify it to get 9/10. 9/10 is your answer

Final answer:

To simplify 6 x 3/20, we first perform the multiplication to get 18/20. Then, we divide both the numerator and denominator by their greatest common divisor, which is 2, resulting in 9/10.

Explanation:

Firstly, in the given expression, 6 x 3/20, the order of operations (BIDMAS/BODMAS) requires us to perform multiplication and division from left to right. So, we multiply 6 and 3 to get 18. This gives us a new expression, 18/20. Then, we simplify this fraction by finding the highest number that both the numerator (18) and denominator (20) can be divided by, which is 2. So we divide both by 2, getting us 9/10. So, 6 x 3/20 simplifies to 9/10 in its simplest form.

Choose the correct ordered pair !!

Answers

It is B.

x+y=3
y=9

To solve the equation you would substitute 9 in for y (in the first equation) and get
x+9=3
You would then subtract 9 from both sides of the equation to get
x=-6
B is the only choice where -6 is first in the ordered pair, but just to make sure, you could substitute -6 back in to the equation to get
-6+y=3
Add 6 to both sides to get y=9, and you know that the correct ordered pair is
(-6,9)

First, let's plug the information we have into the equation.
x + 9 = 3

Next, you would have to do is isolate the x. To do this, you would subtract both sides by 9.
x + 9 = 3
x = -6

So, this is what we know.
y = 9
x = -6

Now, all you would have to do is change them into coordinates. (x,y)
(-6,9)

Your answer would be B. (-6,9).

NEED ANSWER ASAP!!! a compound inequality is graphed, and its graph consists of all real number. which open sentence could have resulted in this solution set? A. r < 5 or r < -1 B. r < 5 or r > -1 C. r > 5 or r < -1 D. r > 5 or r > -1

Answers

When we join two inequalities with an “or,” we unite their graphs – we include all solutions to *both* inequalities. Let’s first look at graphs of each of the four inequalities first, and then we’ll see when we unite them.

r < 5 starts with a hollow circular mark on 5 (since 5 isn’t included in r), and includes everything from there to negative infinity

r > 5 starts with that same mark, but its solutions include everything from there to positive infinity (except 5)

r > -1 starts at -1 and includes everything from there to positive infinity (except -1), and r < -1 stretches to negative infinity (except -1).

We want to join together two inequalities so that their solutions span from negative to positive infinity (all real numbers); which of our options include negative infinity, and which include positive infinity?

Negative infinity: r < 5, r < -1
Positive infinity: r > 5, r > -1

We could try joining r > 5 and r < -1, but then we’d be exclude all of the real numbers between and including -1 and 5. The graphs of r < 5 and r > -1 pass right by each other and continue infinitely off to negative and positive infinity respectively, so all possible real numbers will be included in their combined range.

So, our solution is “r < 5 or r > -1”.

the answer is “r < 5 or r > -1”.

Which graph represents the solution set for -4(1-×)<-12+2×?

What is the measure of ∠SPQ in this rhombus?
m∠SPR = (2x+13)°
m∠QPR = (3x−12)°

Answers

The measure of ∠SPQ in the rhombus PQRS, based on ∠ SPR = (2x+13)°, and ∠ QPR = (3x-12)°, is the sum of the two angles of ∠ SPR and ∠ QPR, which equal the whole or ∠ SPQ, in other words (2x+13)° + (3x-12)Â°.

Solution:

In a Rhombus The diagonals bisect the angles.

m∠SPR=m∠QPR

Substituting the given values :

2x+13=3x-12

Subtracting 2x both sides:

13=3x-2x-12

13=x-12

Adding 12 both sides:

x=25.

m∠SPR=2x+13=2(25)+13=50+13=63

m∠SPQ=2∠SPR

m∠SPQ=2m∠SPR

m∠SPQ=2x63=126

m∠SPQ= 126 degrees
