Determine the value of x. DO,k(x, 9) → (–10, –6)
Answers
k(x,9) = (-10,-6)
k*x = -10
k*9 = -6 Distributive property of multiplication
k*9 = -6
k = -6/9
k = -2/3 Get the value of k to solve for the value of x.
k*x = -10
-2/3 * x = -10
x = -10 ÷ -2/3
x = -10 * -3/2
x = (-10 * -3)/2
x = 30/2
x = 15 Choice D.
Answer:
The answer is D.

22.3 is the value of Square root of 498 to the nearest tenth. Option C is correct
What is Number system?
A number system is defined as a system of writing to express numbers.
An approximation is anything that is similar, but not exactly equal, to something else.
A number can be approximated by rounding.
We need to find the Square root of 498 to the nearest tenth.
square root of Four hundred ninety eight
22.315
On tenth place right side the value is one which is less than five, so the tenth position remains same.
22.3 is the value Square root of 498.
Hence 22.3 is the value Square root of 498.

wide has a semicircle cut out of it.
Find the area of the paperboard that remains. Use the value 3.14
for π, and do not round your answer. Be sure to include the correct unit in your answer.
Answers
Answer:
The remaining area of the paperboard is 363 square inches.
Step-by-step explanation:
The length of the rectangular board = 26 inches
The width of the rectangular board = 20 inches.
Now, the area of the board = square inches
Now, a semicircle has been cut out of it.
Let is assume that the diameter of the semicircle be 20 inches.
So, radius will be = 10 inches
Area of semicircle is =
So, we get : Area =
= 157 square inches.
Now after cutting the semi circle, the area remained = square inches.
Therefore, the remaining area of the paperboard is 363 square inches.
Answer:
See below.
Step-by-step explanation:
Find the area of the rectangle using A = l*w = 26*20 = 520.
Now find the area of the semi circle using A = 1/2 πr². Since the instructions do not say the diameter of the semi circle assume it is 20 or 26.
If it is 20: r = 10 and the area is A = 1/2 π10²=50π = 157.
If it is 26: r = 13 and the area is A = 1/2π13² = (84.5)π = 265.33.
The area of the paperboard that remains will be the area of the rectangle minus the area of the semi circle.
If the diameter of the semi circle is 20 then 520 - 157 = 363.
If the diameter of the semi circle is 26 then 520 - 254.67.

Step-by-step explanation:
This a right triangle so we will use the Pythagorian theorem. x is the hypotenus.
■■■■■ Pythagorian theorem ■■■■■
● x^2 = √10^2 + √10^2
● x^2 = 10 + 10
● x^2 = 20
● x = √20 yd
The missing the side of the triangle is x = 2√5 yd
We can use Pythagoras' theorem to identify the missing side x because the triangle is right angled.
We have the Pythagorean theorem.
a² = b² - c²
where a represents the hypotenuse
The hypotenuse of the question is x.
Fill in the blanks with the values from the above formula.
We now have
x² = (√10)² + (√10)²
x² = 10 + 10
x²
Calculate the square root of both sides.
The final solution is as follows:
x = 2√5 yd
