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

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

The length of a side of an equilateral triangle is 12. find the length of the altitude
Final answer:
To calculate the altitude of an equilateral triangle with side length 12, divide the side by 2 and multiply by [tex]\(\sqrt{3}\)[/tex] giving an altitude of approximately 10.3923 units.
Explanation:
To find the length of the altitude of an equilateral triangle with a side length of 12, you can use the Pythagorean theorem. The altitude of the equilateral triangle creates two 30-60-90 right triangles. The altitude is the longer leg in this case, and the side of the triangle is the hypotenuse. In a 30-60-90 triangle, the longer leg (altitude) is [tex]\(\sqrt{3}\)[/tex]times the shorter leg (half of the side of the triangle).
First, divide the side of 12 into two to get the shorter leg of the right triangle, which is 6. Then, multiply 6 by \(\sqrt{3}\) to find the length of the altitude. This results in:
[tex]\(6 \times \sqrt{3} = 6\sqrt{3} \approx 10.3923\)[/tex]
Therefore, the altitude of the equilateral triangle is approximately 10.3923 units long.
how do you do 36-7p=-7(p-5)
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.Learn more about Linear equations here:https://brainly.com/question/32634451

Kendra is making a large salad for a party. She buys lettuce for $2.25 per pound and tomatoes for $2.65 per pound. She spends at least $8.
Let x represent the number of pounds of lettuce that Kendra buys. Let y represent the number of pounds of tomatoes that Kendra buys.
Which inequality represents this situation?
A. 2.25x+2.65y>8
B. 2.25x+2.65y<8
C. 2.25x+2.65y≤8
D.2.25x+2.65y≥8
Answer: The correct option is
(D) [tex]2.25x+2.65y\geq8.[/tex]
Step-by-step explanation: Given that Kendra is making a large salad for a party. She buys lettuce for $2.25 per pound and tomatoes for $2.65 per pound. She spends at least $8.
x represent the number of pounds of lettuce that Kendra buys and y represent the number of pounds of tomatoes that Kendra buys.
We are to select the inequality that represents the situation.
We have
total amount of money that Kendra spends on lettuce is given by
[tex]a_l=2.5\times x=2.5x[/tex]
and the total amount of money that she spends on tomatoes is
[tex]a_t=2.65\times y=2.65y.[/tex]
Therefore, the inequality can be written as
[tex]a_l+a_t\geq 8\\\\\Rightarrow 2.25x+2.65y\geq8.[/tex]
Thus, option (D) is CORRECT.

Sonia graphs the equations y = –x2 + 4x and y = x – 4 to solve the equation –x2 + 4x = x – 4. Her graph is shown below. What are the solutions of –x2 + 4x = x – 4? A.–5 and 0
B.–5 and –1
C.–1 and 4
D.0 and 4
Answer
C.–1 and 4
Explanation
Solving the equations y = –x² + 4x and y = x – 4
–x² + 4x = x – 4
x² - 4x + x = 4
x² - 3x = 4
x² - 3x + (3/2)² = 4 + (3/2)²
(x - 3/2)² = 4 + 9/4
= 6.25
x - 3/2 = √6.25 or x - 3/2 = -√6.25
x = 2.5 + 1.5 x = -2.5 + 1.5
= 4 = -1
What is the slope of a line that is perpendicular to the line y = 8x + 5?
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]
