Answer:
mass on day 1: 3
mass on day 2: 9
mass on day 3: 27
Step-by-step explanation:
using this equation, y = 3^x, you can plug in 1, 2, and 3 for 'x' to get the value of 'y' (which represents the mass on specific days)
3^1 = 3
3^2 = 9
3^3 = 27

n a survey of 3100 people who owned a certain type of car, 775 said they would buy that type of car again. What percent of the people surveyed were satisfied with the car?
answer : 25%
775 / 3100 were satisfied
to make this a percentage, you need to make the demoninator 100 : 3100/100=31
and then you divide the numerator by this : 775/31= 25
Is x = 5 a solution to the equation 19 - x= 14?
A. Yes, because 19 - 5 = 14 is not true.
B. No, because 19 - 5 = 14 is not true.
C. Yes, because 19 - 5 = 14 is true.
D. No, because 19 - 5 = 14 is true.
Answer:
C.
Step-by-step explanation:
If you plug in the value of x (5) into the equation you get...
19-5=14
Then solve.
14=14
Is 14=14?
Yes!
Meaning that it is a solution.

Write down in terms of n an expression of the nth terms?
Answer:
A. nth term = 4 + (n - 1) -3
B. nth term = -7 + (n - 1) -5
Step-by-step explanation:
A. 4, 1, -2, -5, -8
First term, a = 4
Common difference, d = 1 - 4 = -3
nth term = a + (n-1)d
nth term = 4 + (n - 1) -3
B. -7, -12, -17, -22, - 27
First term, a = -7
Common difference, d = -12 - (-7)
= -12 + 7
= -5
nth terms = a + (n - 1)d
nth term = -7 + (n - 1) -5

y=[?]°
Answer:
Since there are already 2 angles shown, which are 48 and 90 (indicated by the square in the bigger triangle, we can set up an equation.
48 + 90 + y = 180
138 + y = 180
-138 + 138 + y = 180 - 138
y = 42°

Plz help me and hurry
Answer:
A. For each input value, x, there is exactly one output value, y.
Step-by-step explanation:
A function always have exactly one output value (y-value) that is related or assigned to each input value (x-value), however, two different x-values can have the same y-value.
In the graph given, although two different values have the same y-value, every x-value has exactly one y-value corresponding to it. No x-value has two different y-values.
Therefore, the graph represents a function.

11) -6x – 9y = 0
-24x = 36y
Answer:
x = 0, y = 0
or
(0, 0)
Step-by-step explanation:
-24x - 36y = 0
divide the equation by 4
-8x - 9y = 0
-6x - 9y = 0
multiply the second equation by -1
6x + 9y = 0
add them together
-8x - 9y = 0
6x + 9y = 0
-2x = 0
x = 0
substitute into the second equation
-8 * 0 - 9y = 0
-9y = 0
y = 0

1. The ratio of boys to girls is 4/5. If there
are 24 boys, how many girls are there?
Given:
The ratio of boys to girls is [tex]\dfrac{4}{5}[/tex].
Number of boys = 24
To find:
The number of girls.
Solution:
We have,
Boys: Girls = 4:5
Let the number of boys be 4x and number of girls be 5x.
[tex]4x=24[/tex]
[tex]x=\dfrac{24}{4}[/tex]
[tex]x=6[/tex]
Now,
Number of girls = [tex]5x[/tex]
= [tex]5(6)[/tex]
= [tex]30[/tex]
Therefore, the number of girls is 30.

Answer:

Step-by-step explanation:
Clark Kent and Lois Lane were laying on a blanket, enjoying a relaxing picnic when Clark noticed a giant asteroid approaching Earth. Clark calculates the angle of elevation of the asteroid's approach to be 62°. Lois' penthouse apartment is also in the pathway of the asteroid's approach, 100 feet above ground. Clark's eye is 75 feet from the base of Lois' building. Will the asteroid take out Lois' penthouse apartment?
Answer:
The asteroid will not take out Lois' penthouse.
Step-by-step explanation:
Since the distance between Clark and the base of Lois' building is x = 75 feet and the asteroid is at an angle of elevation of Ф = 62°. These two components form a right-angled triangle with opposite side h which is the height of the asteroid above the ground.
So, by trigonometric ratios,
tanФ = h/x
h = xtanФ
h = 75 ft × tan62°
h = 75 ft × 1.8807
h = 141.1 feet
Since h = height of asteroid above the ground = 141.1 feet is greater than height of the penthouse above the ground = 100 feet, the asteroid will not take out Lois' penthouse.
