Answer:

true

Step-by-step explanation:

Answer:

Yes, the statement "An exponential decay function represents a quantity that has a decreasing halving time" is true. In addition, this process can be expressed by the following differential equation, where N is the quantity and λ (lambda) is a positive rate called the exponential decay constant: d N d t = − λ N . {displaystyle {frac {dN} {dt}}=-lambda N.}

Answer:

CBD is 120 degrees

Step-by-step explanation:

x=30

4x30+30+30=180

Answer: 120°

Step-by-step explanation:

x + 4x + x = 180° (Since the sum of a straight line is 180°)

6x = 180°

x = 30°

To find the angle of 4x, we need to multiply 4 x 30°

120°

Answer:

Its 24! hope this helped!

Answer:

45 degrees.

I hope I'm right.

Answer:

180 ride tickets

Step-by-step explanation:

Create a proportion where x is the number of tickets he can buy with his $96:

[tex]\frac{8}{15}[/tex] = [tex]\frac{96}{x}[/tex]

Cross multiply and solve for x:

8x = 1440

x = 180

So, he can buy 180 ride tickets

Answer:

180 tickets

Step-by-step explanation:

8x = 15

96x = ?

96/8 = 12

12 x 15 = 180

Answer:

y = 10x

(x is a set of odd numbers between 11 and 99)

Step-by-step explanation:

Given;

divisor = 20

remainder, = 10

let the 3 - digits dividend = y

let the quotient = x

Arranging all in mixed fraction;

[tex]\frac{y}{20} = x\frac{10}{20} \\\\\frac{y}{20} = \frac{10x}{20} \\\\\frac{y}{20} = \frac{x}{2} \\\\2y = 20x\\\\y = 10x[/tex]

where x = 11, 13, 15, 17, 19 - - - - - - - 99

The divisor would be between 5 and 49. So I chose 38. 38x20 is 760. 760+ 10 (which is the remainder) is 770.

Therefore, The divisor would be 38 and the dividend would be 770.

Have a great day!

slope is y2-y1/x2-x1

if this was set up correctly it would be 17 - 1/18 - 14

The student simply switched the places of the y change calculation.

...............................................................................................................................................

The answer is D. She should have used 8-1 as the denominator since she used 17-14 as the numerator.

B. 3 ( 12 - x ) = 6

[tex]3(12 - x) = 6 \\ (12 - x) = 2 \\ x = 10[/tex]

Answer:

3 is your base

4 is your height

(this is for the area of the bottom)

3 x 4 = 12

12 divided by 2 = 6 is your area of the bottom

6 x 4(height) = 24

24 divided by 3(times 1/3) = 8

Step-by-step explanation:

Answer:

4, A fraction is the numerator divided by the denominator.

Step-by-step explanation:

Fractions do not involve multiplying! It is dividing, so we can rule out all the multiplication related questions.

The top number of a fraction is the numerator 2/3.

The bottom number is the denominator 2/3.

The / is a sign of division.

So, 1 is wrong and 4 is right.

Answer:

62.2 inches

Step-by-step explanation:

a²+b²=c²

Plug in your known variables.

50²+37²

This will equal to 3869

Now you will have 3869 = c²

Square root both sides

√3869 = √c²

62.2 inches ≈ c

in total there are 6,4,8 which equals 18 .There are 18 balls in total. but Alex removed 3 so now there are 15 balls. There 3 different colors and 15 balls. So there is a 5% out of 15 that you will get a certain color .To find the probability you need to calculate all the possible outcomes.

G=Green   R=Red    P=Purple

G,R,P

G,P,R

P,G,R

P,R,G

R,P,G,

R,G,P

There is 6 different outcomes, 15 balls and a 5% chance to get a certain color so if you want to exactly get G,R,P there is a (15 divided by 6) chance to get that order.

(I'm not good at calculating that part.)

Answer: Intercepts are points where a graph crosses over an axis

Step-by-step explanation: the x-intercepts are points where the graph intercepts the x-axis. These are also referred to as roots or zeroes of a function

The y-intercepts are points where the graph intercepts the y-axis. Fuctions only have one y-intercept

Answer:

answer: 92

Step-by-step explanation:

These Will add up to 360 in total so b and c our 92 because 92 + 92 + 88 + 88 = 360 Hope that helps!

Step-by-step explanation:

here's your solution

==> 88° + b° = 180°. [ linear pair ]

==> b° = 180° - 88°

==> b° = 92°

b° = c°. [ vertical angle ]

==> c° = 92°
