Answer:

A=122

Step-by-step explanation:

The sum of degree of angles in a triangle=180

Angle a =180-43-15=122

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:

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°

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:

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

Answer:

Hello! answer: 62.8

Step-by-step explanation:

Cirmcumfrence can be found by doing

diameter × pi are diameter is 20 and pi is 3.14

20 × 3.14 = 62.8 therefore the circumference is 62.8 HOPE THAT HELPS!

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

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.

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: 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:

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
