Answer:

25 grams

Step-by-step explanation:

Three half live

1/2 * 1/2 * 1/2 = (1/2)³ = 1/8

There would be 1/8 of the original amount left

185 * 1/8 = 23.125

Rounded

25 grams

Answer:

9x2 +42x + 24 is (x + 4) (9x + 6)

9x2 + 30x + 24 is (3x + 6) (3x + 4)

9x2 + 58x + 24 is (9x + 4) (3x + 4)

I tried reversing it, instead of doing these - 9x2 + 58x + 24 I did (9x + 4) (3x + 4)

Answer:

m =(-7-√73)/2=-7.772

Step-by-step explanation:

Answer:

m=−7/2+1/2√73 or m=−7/2+−1/2√73

Step-by-step explanation:

Let's solve your equation step-by-step.

m2=−7m+6

Step 1: Subtract -7m+6 from both sides.

m2−(−7m+6)=−7m+6−(−7m+6)

m2+7m−6=0

For this equation: a=1, b=7, c=-6

1m2+7m+−6=0

Step 2: Use quadratic formula with a=1, b=7, c=-6.

m=−b±√b2−4ac/2a

m=−(7)±√(7)2−4(1)(−6)/2(1)

m=−7±√73/2

m=−7/2+1/2√73 or m=−7/2+−1/2√73

Answer:

Actually Welcome to the concept of Equilateral triangles.

Since, from the name itself, equilateral triangles have all sides and angles equal.

Hence the correct answer is

==> D. All sides are the same length.

Answer:

7

Step-by-step explanation:

Answer:

7 units

Step-by-step explanation:

To find the distance between two points, we use the distance formula:

[tex]d = \sqrt{(x_{2}-x_1)^2 + (y_2-y_1)^2 }[/tex]

Plug in what you know.

[tex]d = \sqrt{(-5 - 2)^2 + (-2 - (-2))^2 }[/tex]

Evaluate the double negative.

[tex]d = \sqrt{(-5 - 2)^2 + (-2 + 2)^2 }[/tex]

Evaluate the parentheses.

[tex]d = \sqrt{(-7)^2 + (0)^2 }[/tex]

Evaluate the exponents.

[tex]d = \sqrt{(49) + (0) }[/tex]

Add.

[tex]d = \sqrt{(49)[/tex]

Evaluate the radical.

d = ±7

Since distance cannot be negative, our answer is 7.

The distance between the two points is 7 units.

Answer:

The cost of admission

Step-by-step explanation:

Noelle only has to pay once for admission and buy multiple tickets for each ride.

========================================================

Work Shown:

x = smaller number

x+8 = larger number, since it's 8 more than the smaller value

Add up those two expressions, and set the sum equal to 80.

Then solve for x.

x+(x+8) = 80

2x+8 = 80

2x = 80-8 ... subtract 8 from both sides

2x = 72

x = 72/2 .... divide both sides by 2

x = 36

The smaller value is 36 while the larger value is x+8 = 36+8 = 44

Note how 36+44 = 80 to help verify the answer.

Answer:

34.

Step-by-step explanation:

80 = (34 + 8) + x

80 = 42 + x

38 = x

^^ that is an answer, but the question asks for the SMALLER number... Which is up at the beginning of my equation.

I hope this helps. I'm not entirely sure if it's correct, but it's worth a shot... lol

Answer:

Step-by-step explanation:

6 - 3x = -15

Move all terms not containing x to the right side:

-3x = -15-6

-3x = -21

Solve for x by dividing -21 by -3

Answer:

Visual artifacts are anomalies apparent during visual representation as in digital graphics and other forms of imagery, especially photography and microscopy.

Answer:

The number you would add to both sides of the equation to use the "Completing the Square" method would be 16.

Step-by-step explanation:

To find the number to add to both sides of an equation to complete the square, divide the first-degree term's coefficient by 2 and square your remainder. In this case, the coefficient of the first-degree term is -8. After dividing by 2 and squaring it, you'll get 16, so that is the number you must add to both sides of the equation in order to complete the square.

Answer:

4.118 * 10^6

Step-by-step explanation:

When you multiply exponents, you just add the exponents together, so 10^2 * 10^3 is 10^5. Then you just multiply the 7.1 and the 5.8, which is 41.18. However, scientific notation should have only 1 digit above the decimal spot, so you make the number smaller from 41.18 to 4.118, so you add 1 exponent to the 10^5.

41.18*10^5 = 4,118*10^6

(EDIT, THE GUY WHO COMMENTED IS CORRECT, SCIENTIFIC NOTATION IS WHEN THE DIGIT IS GREATER THAN 1 OR LESS THAN 10, SO IT WOULD BE 4.118*10^6)

Answer:

411.8 · [tex]10^{4}[/tex]

Step-by-step explanation:

7.1 · 10³ × 5.8 · 10²

7.1 × 5.8 = 41.18

10³ + 10² = [tex]10^{5}[/tex]

41.18 · [tex]10^{5}[/tex]

Scientific notation can only have one digit after the decimal.

411.8 · [tex]10^{4}[/tex]

Answer:

12 ft

Step-by-step explanation:

Since the doors are similar then the ratios of corresponding dimensions are equal.

let x be the height of the bigger door, then

[tex]\frac{small}{big}[/tex] : [tex]\frac{3}{x}[/tex] = [tex]\frac{2}{8}[/tex] ( cross- multiply )

2x = 24 ( divide both sides by 2 )

x = 12

Height of the bigger door is 12 ft

Answer:

x = 3±√5

Step-by-step explanation:

Given the quadratic equation;

0 = x² – 6x + 4

Swap sides

x² – 6x + 4=  0

Subtract 4 from both sides

x² – 6x + 4 - 4=  0 - 4

x² – 6x = -4

Complete the square;

Add the square of half of coefficient of x to both sides

Coefficient of x = -6

Half of Coefficient  of x = -6/2 = -3

square of the half of Coefficient of x = (-3)²

Add (-3)² to both sides

x² – 6x + (-3)² = -4 + (-3)²

(x-3)² = -4 + 9

(x-3)² = 5

Take the square root of both sides

x - 3 = ±√5

x = 3±√5

This gives the solution to the equation
