Krisa divides a number by 10. Then she divides the same number by 50. Which quotient is greater? How can you tell?

Answers

Step-by-step explanation:

the quotient of 10 is bigger than the quotient of 50

The quotient is greater when number is divided by 10.

What is division?

The division is the process of repetitive subtraction. It is the inverse of the multiplication operation. It is defined as the act of forming equal groups.

Given,

Krisa divides a number by 10

Let the number be x

x/10 = y  

x = 10y                ------(1)

Same number is divided by 50

x/50 = z

x = 50z               --------(2)

By equation (1) and (2)

10y = 50z

y = (50/10)z

y = 5z

⇒ y > z

Hence, quotient when number divided by 10 is greater.

Find the solution to the equation algebraically. Check your answer. k - 16 = 4

Answers

Answer:

k= 20

Step-by-step explanation:

You start with this equation:

k-16=4

Add 16 on both sides.

k=4+16

Simply.

k=20

If you want to check your answer, you can just plug 20 into where k is back into the equation:)

Hope this helps!

Hey there!

k - 16 = 4


ADD 16 to BOTH SIDES

k - 16 + 16 = 4 + 16

CANCEL out: -16 + 16 because it give you 1

KEEP: 4 + 16 because it give you the x-value

NEW EQUATION:

k = 4 + 16

k = 16 + 4


SIMPLIFY IT!

k = 20


Therefore, your answer is: k = 20

Write x² - 6x + 3 in the form (x-a)²+ b.​

Answers

Answer:

(x + 3)² - 12

Step-by-step explanation:

x²+6x-3

=  x²+ 6x + 9 - 12

= (x + 3)² - 12

The form of x² - 6x + 3 can be written as (x-3)² - 6.

What is a quadratic equation?

A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is  ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.

We are given that;

Equation= x² - 6x + 3

Now,

To write x² - 6x + 3 in the form (x-a)²+ b, we can use the method of completing the square. This involves adding and subtracting a constant term to make the expression a perfect square trinomial. Here are the steps:

Write x² - 6x + 3 as x² - 6x + ___ - ___ + 3, leaving two blanks for the constant term.

To find the constant term, divide the coefficient of x by 2 and square it. In this case, -6/2 = -3 and (-3)² = 9. So we fill in the blanks with 9 and get x² - 6x + 9 - 9 + 3.

Factor the first three terms as a perfect square: (x - 3)² - 9 + 3.

Simplify the last two terms: (x - 3)² - 6.

Compare with the form (x-a)²+ b and identify a and b. In this case, a = 3 and b = -6.

Therefore, by the given equation the answer will be (x-3)² - 6.

The 4 interior angles in the square are each 90 degrees. The four angles formed by the intersection of the 2 diagonal lines are each 90 degrees. The rest of the angles <PQT, <RQT, etc. Are all 45 degrees.

Answer:

The following angles are 45 degrees: SPT, QPT, PQT, RQT, QRT, SRT, RST, PST.

The following angles are 90 degrees: STP, PTQ, QTR, RTS

Step-by-step explanation:

Notice that it is a square. Since it is a square, any diagonal line drawn from a corner to the opposite corner will bisect the angle at both corners. Since in a square each angle at each corner is 90 degrees, we know that the angles listed above are 45 degrees.

There are multiple ways to arrive at the conclusion that angles STP, PTQ, QTR, RTS are all 90 degrees. The easiest way to arrive at that answer is looking at each triangle. Notice how the square is divided into 4 triangles. Each triangle contains two 45 degree angles. Since the internal angles of each triangle must sum to 180 degrees, this means the last angle is 90 degrees.
