The half-life of a certain radioactive substance is 14 days. There are 6.6 grams of the substance
present initially. Which equation represents the number of grams of the radioactive substance
on day 42?
Answers
Answer:
A(t) = 0.825 g
Step-by-step explanation:
To solve this for amount remaining, we will use the equation;
A(t) = A_o × (½)^(t/t_½)
We are given;
Initial amount; A_o = 6.6 g
Half life; t_½ = 14
Time elapsed; t = 42
A(t) is amount of substance remaining
Thus;
A(t) = 6.6 × (1/2)^(42/14)
A(t) = 6.6 × (1/2)³
A(t) = 6.6 × ⅛
A(t) = 0.825 g

Solve 9x-17=5x-1
What is x?
Answers
Answer: x=4 hope this helps:)
Step-by-step explanation:
Answer:
x=-4
Step-by-step explanation:
9x-17=5x-1 isolate X
9x-17=5x-1 add +1 to each side of the equation 9x-17+1=5x-1+1 the ones cancels out... 9x-16=5x
add -9x to both sides..... 9x-16+9x=5x-9x...... 9x-9x-16=5x-9x
-16=5x-9x subtract 5x-9x
-16= - 4x divide both sides by -4
-4=x or x=-4

What factoring method do you use to factor u²+70
1) difference of
squares
2) GCF
3) not foctorable
4) factor trinomial
Answers
Answer: 3) Not factorable
We cannot use the difference of squares method because we don't have a subtraction going on (ie "difference") and we don't have two perfect squares. The value 70 is not a perfect square.
We cannot factor out a GCF since the GCF here is 1, and that doesn't really affect things. Choice 4 is also not applicable because we don't have a trinomial. A trinomial has three terms.

I was confused over this particular question. if you could help, I'd really appreciate it.
Answers
Step-by-step explanation:
The 1st equation is in slope-intercept form.
=> Slope = 4
The 2nd equation is in point-slope form.
=> Slope = -1/4
Since their slopes are unequal,
The lines are not parallel to each other.
However the product of their slopes is -1,
Therefore the lines are perpendicular to each other.
The answer is the 2nd option.

2x + 3y = 11
5x + 3y = 14
Answers
x=-3/5y+14/5
Answer:
x = 1 ; y = 3
Step-by-step explanation:
5(2x + 3y = 11)
2(5x + 3y + 14)
(distribute)
10x + 15y = 55
10x + 6y = 28
(subtract)
9y = 27
(divided 9 to both sides)
9 divided by 9 cancels out and 27 divided by 9 = 3
so..
y = 3
now, using any equation, (i’ll be using 2x + 3y =11) plug in the y value to find the x value
2x + 3y = 11
2x + 3(3) = 11
(multiply 3 x 3)
2x + 9 = 11
(subtract 9 from 9 and 11)
2x = 2
(divide 2 from both sides)
2 divided by 2 = 1
therefore...
x = 1

A rectangular ground has the breadth 80percent of length and perimeter is 360m. Find the cost of planting the ground at Rs 8 per m^2
Answers
Answer:
Rs 64000
Step-by-step explanation:
Since breadth B = 80% of length L, B = 0.8L
Perimeter, P = 2(L + B) = 360m
Substituting B = 0.8L into P, we have
2(0.8L + L) = 360 m
2(1.8L) = 360 m
3.6L = 360 m
L = 360m/3.6
L = 100 m
So, B = 0.8L = 0.8(100 m) = 80 m
The area of the rectangular ground is A = LB = 100 m × 80 m = 8000 m²
So, the cost of planting the ground at Rs 8 per m² is Rs 8 per m² × 8000 m² = Rs 64000

Answer:
[tex]y=-\frac{1}{3} x+5[/tex]
Step-by-step explanation:
This question is asking for slope-intercept form which is y=mx+b, where m is the slope and b is the y-intercept. First, find the slope; this can be done in two ways, counting change in y and x then dividing, or using the formula [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]. Either way for this graph the slope comes out as -1/3. Next, find the y-intercept, this is where the line intersects with the y-axis. In this case, the line touches the axis at 5, therefore 5 is the value of b.
