Explanation:
The arc markings for each angle show that we have two pairs of congruent angles (angle O = angle Q, angle M = angle R). This takes care of the two "A"s in "ASA". The tickmarks show us that the sides MO and RQ are the same length, so this takes care of the "S" of "ASA". Note the congruent sides are between the angles mentioned. The order is important.

The TV chef didn't know the first thing about cooking. He was just hired for his wavy blonde hair and charming British accent. So last Tuesday, while the gullible audience thought the chef was mixing up a world-renowned hollandaise sauce, he was actually just mixing a 5 ounce sauce containing 50% tangy mustard with another sauce containing 75% tangy mustard to get a sauce containing 70% tangy mustard. How many ounces of the 75% tangy mustard sauce must the chef have used?
Answers
The number or amount of ounces of the 75% tangy mustard sauce must the chef have used is: 20 ounces .
Number of ouncesFirst step
Since 5 ounce sauce containing 50% tangy
Hence:
5 oz×.50 tangy
=2.50 oz-tangy
Second step
(5+x)×0.7=3.5+0.7x
Third step
2.50+0.75x=3.5+0.7x
Collect like term
0.75x-0.7x=3.5-2.50
0.05x=1
Divide both side by 0.05
x=1/0.05
x=20 ounces
Therefore the number of ounces of the 75% tangy mustard sauce must the chef have used is: 20 ounces .

The equation x^2−8x−5=0 can be transformed into the equation (x−p)^2=q, where p and q are real numbers. What is the value of q?
Answers
Answer:
x = 5
or
x = 3
Step-by-step explanation:
The first term is, x2 its coefficient is 1 .
The middle term is, -8x its coefficient is -8 .
The last term, "the constant", is +15
Step-1 : Multiply the coefficient of the first term by the constant 1 • 15 = 15
Step-2 : Find two factors of 15 whose sum equals the coefficient of the middle term, which is -8 .
-15 + -1 = -16
-5 + -3 = -8
If the equation x²−8x−5=0 can be transformed into the equation (x−p)²=q, then value of q is 21
What is Equation?Two or more expressions with an Equal sign is called as Equation.
To transform the equation x² - 8x - 5 = 0 into the equation (x - p)² = q, we need to complete the square by adding and subtracting a constant term.
First, let's add 5 to both sides to get:
x² - 8x = 5
Applying complete square method
we need to add and subtract 16 inside the parentheses on the left-hand side:
x² - 8x + 16 - 16 = 5
Simplifying the left-hand side gives us:
(x - 4)² - 16 = 5
Adding 16 to both sides gives us:
(x - 4)² = 21
Therefore, the value of q is 21.

You are trying to help Rhonda understand the concept of a 5% slack in the line. You explain that having a 5% slack means that the length is 5% longer than it would be if it were completely straight. You compare ️ABC to Figure DEF, where curve DE is 5% longer than line segment AB.
Enter curve DE, given the curve is 5% longer than line segment АВ.
Answers
The length of the hypotenuse AB is equal to the sum of the square of other two sides AC and BC. The measure of the curve DE is 10.5 units
Pythagoras theoremThe theorem states that the length of the hypotenuse AB is equal to the sum of the square of other two sides AC and BC.
According to the theorem;
AB^2 = AC^2 + BC^2
AB^2 = 6^2 + 8^2
AB^2 = 36 + 64
AB = 10
If the curve DE is 5% longer than line segment АВ, the measure of curve DE is given as;
DE = 1.05 * 10
DE = 10.5
Hence the measure of the curve DE is 10.5 units

The area of the triangle 5yd 16yd 12yd
Answers
The formula for the area of the triangle is A = 1/2bh (1/2•base•height).
Identify your base and height and substitute them into the formula. Since you did not include an image or info in which states the base and height, this is what I can say.
If the base and height are 5 and 12, the area would be 30 yds. (1/2 x 5 x 12)
If the base and height are 5 and 16, the area would be 40 yds. (1/2 x 5 x 16)
If the base and height are 12 and 16, the area would be 96 yds. (1/2 x 12 x 16)
