What is the answer??

Answer:

30 grams

Step-by-step explanation:

half life is 60 days so every 60 days the amount 480 grams will be half

in 240 days will decay  240 /60 = 4 times

once 480 /2 = 240

twice 240 /2 = 120

trice 120 / 2 = 60

four times 60/2 = 30 grams will be left

Answer:

I love ur pfp

Step-by-step explanation:

ANSWER: m∠2 = 120°, m∠3 = 60°; Sample answer: ∠1 and ∠2 are alternate exterior angles, so they have the same measure. ∠2 and ∠3 are supplementary. So, m∠3 = 180° – 120° or 60°.

Answer:

24 inches squared

Step-by-step explanation:

That is a triangle, and the area of a triangle is 1/2(b)(h), which is one half times the base times the height. Let's identify those things.

1/2: the area of a rectangle can be calculated base times the height, and a triangle is half of that rectangle, hence the 1/2

(b) or base: base is usually identified as the horizontal line in the triangle, which is 6 inches in this case.

(h) or height: height is usually the vertical line, and in this case, the vertical line is 8 inches.

Now time for the math:

1/2(6)(8) = 24 inches squared

Answer:

1. 12  2. 12  3.1/8    4. 11  5. -15   6.-60   7.20  8.225

Step-by-step explanation:

Given that :

m=2 and n=16 , p = {1-6 =-5}  then;

1.  m+10 = 2+10 = 12

2. n-4 = 16-4 = 12

3. m / n = 2/16 = 1/8

4. 6m - 1 = 6*2 - 1 = 12 -1 = 11

5. 3p =3* -5 = -15

6.12 p = 12* -5 = -60

7. 12m-4 = 12*2 - 4 = 24 -4 =20

8. 9p² = 9*-5² = 9 * 25 = 225

Answer: i. Cost of adult ticket = $ 30

ii.  Cost of child ticket = $20

Step-by-step explanation:

Define variables:

Let x= cost of 1 adult tickets , y= cost of 1 child tickets.

Form linear equations:

5x+3y = 210      (i)

2x+5y= 160  (ii)

Multiply (i) by 2 and (ii) by 5

10x +6y = 420       (iii)

10x+25y = 800        (iv)

Eliminate (iii) from (iv)

19y = 380

⇒ y= 20

Put this in (i)

[tex]5x+3(20)=210\Rightarrow\ 5x+60 = 210\\\\\Rightarrow\ 5x=150\\\\\Rightarrow\ x=30[/tex]

Hence, Cost of adult ticket = $ 30 and Cost of child ticket = $20

Answer:

y = -4x + 16

Step-by-step explanation:

The slope of the given line is -4

when two lines are parallel, their slopes are equal

That means the slope of the second line is -4 too

Thus, we have to use the point-slope form to write the equation

That will be

y-y1 = m(x-x1)

y-8 = -4(x-2)

y -8 = -4x + 8

y = -4x + 8+8

y = -4x + 16

Answer:

g(h(- 8)) = 119

Step-by-step explanation:

Evaluate h(- 8), then substitute the result obtained into g(x), that is

h(- 8) = (- 8)² - 2 = 64 - 2 = 62, then

g(62) = 2(62) - 5 = 124 - 5 = 119

Answer:

Step-by-step explanation:

Use the distributive property to distribute the outside minus sign to all terms inside parentheses.

1) 5.5x +1 -(1.5x +17) = 5.5x +1 -1.5x -17 = x(5.5 -1.5) +(1 -17)

  = 4x -16

2) x -3x -(-5x) = x -3x +5x = x(1 -3 +5)

  = 3x

34+x+90 =180(Angle sum property of triangle )

124 +x =180

x= 180-124

x= 56

Step-by-step explanation:

[Diagram in image attached]

RS + ST = RT

(6y +3) + (4y + 7) = 60

6y + 3 + 4y + 7 = 60

10y + 10 = 60

10y = 60 - 10

10y = 50

y = 50/10

y = 5

RS = 6y +3 = 6(5) + 3 = 30 + 3 = 33

ST = 4y +7 = 4(5) + 7 = 20 + 7 = 27

RT = 60

{RS + ST = RT

33 + 27 = 60}
