what is the circumference of a circle that’s 9cm

Answer:

That is the formula for solving quadratic equations like:

ax^2+bx+c = 0

You substitute the variables from your quadratic equation to solve them.

Answer:

3. m<GHF= 90 degrees

4. m<DGH= 45 degrees

5. HF=5

6. DE=50

Step-by-step explanation:

3. The measure of angle DGF and EFG are 45 degrees each and 45+45 is 90 degrees. When you subtract 90 from 180, you get 90.

4. A square is also a rectangle and a rectangle has four right angles and it is a rhombus and the diagonals bisect the angles. This means that angle DGH is half of angle DGF and 90/2=45.

5. The diagonals of a square are congruent so it is also 5.

6. You use the Pythagorean Theorem and 5^2 + 5^2=50

The diagonals of square DEFG intersect at H. The measure of the following option; 3. m∠GHF= 90 degrees. 4. m∠DGH= 45 degrees 5. HF=5 6. DE=50

That rectangle whose all sides are equal is called a square.

A square is always a rectangle, parallelogram, a rhombus, and a quadrilateral but its reverse statement may or may not be true.

(ie it is not always necessary that a rectangle is a square or a parallelogram is a square or a rhombus is a square).

The diagonals of square DEFG intersect at H.

Given that EH = 5, we need to find the measure of the following option;

3. The measure of ∠DGF and ∠EFG are 45 degrees each .

The sum of the angle of the bisector of diagonal 45 + 45 = 90 degrees.

When you subtract 90 from 180, you get 90.

4. A square is also a rectangle and a rectangle has four right angles and it is a rhombus and the diagonals bisect the angles.

This means that ∠DGH is half of ∠DGF

90/2 = 45.

5. The diagonals of a square are congruent so HF is 5.

6. By Pythagorean Theorem

[tex]DF^2 = 5^2 + 5^2\\\\DF = \sqrt{50}[/tex]

Answer:

20​% alcohol = 1 gal

10​% alcohol = 9 gal

Step-by-step explanation:

Let

x = 20​% alcohol

y = 10​% alcohol

x + y = 10 (1)

0.20x + 0.10y = 10*0.11

0.20x + 0.10y = 1.1 (2)

From (1)

x = 10 - y

Substitute x = 10 - y into (2)

0.20x + 0.10y = 1.1

0.20(10 - y) + 0.10y = 1.1

2 - 0.20y + 0.10y = 1.1

- 0.20y + 0.10y = 1.1 - 2

-0.10y = -0.9

y = -0.9/-0.10

y = 9 gal

substitute y = 9 into (1)

x + y = 10

x + 9 = 10

x = 10 - 9

x = 1 gal

20​% alcohol = 1 gal

10​% alcohol = 9 gal

Explain how 3 * 65 could be used for (0.03) * (0.65)

0.03 is to 2 decimal places and 0.65 is also to 2 decimal places

In total, we have: [tex]2 + 2 = 4[/tex]

So, to get (0.03) * (0.65) from 3 * 65.

Simply calculate the product: 3 * 65

Then divide by 10 to the power of the sum of the decimal places i.e. 4

This is shown below

(0.03) * (0.65)

Express as fraction

[tex](0.03) * (0.65) = \frac{3}{100} * \frac{65}{100}[/tex]

[tex](0.03) * (0.65) = \frac{3*65}{100*100}[/tex]

[tex](0.03) * (0.65) = \frac{3*65}{10^2*10^2}[/tex]

[tex](0.03) * (0.65) = \frac{3*65}{10^4}[/tex]

Answer:

46

Step-by-step explanation:

6 + 4 x {3+7} [B.O.D.M.A.S rule] (First bracket)

= 6 + 4 × 10. (Then Multiplication)

= 6 + 40. ( At last addition)

= 46 (Ans)

The simplified value of the expression  6 + 4 × {3 + 7} is 100.

PEMDAS rule states the correct order of simplifying an expression is as follows -: Parenthesis, exponents, multiplications, divisions, additions, and, subtractions.

Given, An expression 6 + 4 × {3 + 7}.

First, we'll add 6 and 4 as 3 and 7 are inside curly brackets,

not in parentheses.

Therefore,

6 + 4 × {3 + 7}.

= 10 × {3 + 7}.

Now, we can either distribute the terms or take the addition and multiply.

= 10 × 10.

= 100.
