Answer:
$40
Step-by-step explanation:
We can call the total x.
30% = 3/10, so $12 = 3/10 of the total.
This means that 12 = 3/10 of x, or 12 = 3/10 * x.
Solving,
12 = 3/10 * x
multiply both sides by 10 to get rid of the fraction
120 = 3 * x
divide both sides by 3 to get x, the total, by itself
40 = x
This means that the total is $40.
Answer:
$40Step-by-step explanation:
Let the total be x
30% of total is $120.3x = 12x = 12/0.3x = 40Total is $40

A negatively charged balloon moves close to another balloon. They then repel each other. What can be said about the other balloon?
Answer: B: It has a negative charge.
Step-by-step explanation:
According to theory espoused by the French physicist, Charles-Augustin de Coulomb, like charges charges will repel each other and unlike charges will attract one another.
This means that objects with negative charges will repel each other. As the first balloon in the question was negatively charged, it would only repel the other balloon if it was negatively charged as well.

In an agricultural study, the average amount of corn yield is normally distributed with a mean of 185.2 bushels of corn per acre, with a standard deviation of 23.5 bushels of corn. If a study included 1200 acres, about how many would be expected to yield more than 206 bushels of corn per acre?
Answer:
About 786 would be expected to yield more than 180 bushels of corn per acre
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean and standard deviation , the zscore of a measure X is given by:

Assume an exponential function has a starting value of 11 and a decay rate of 47%. Write an equation to model the situation.
Answer:
[tex]C(t)=11\cdot0.53^t[/tex]
Step-by-step explanation:
Exponential Decay Function
The exponential function is often used to model natural growing or decaying processes, where the change is proportional to the current quantity.
An exponential decaying function is mathematically written as:
[tex]C(t)=C_o\cdot(1-r)^t[/tex]
Where:
C(t) is the actual value of the function at time t
Co is the initial value of C at t=0
r is the decaying rate, expressed in decimal
We are given a starting value of Co=11 and a decay rate of r=47%=0.47.
The equation of the model is:
[tex]C(t)=11\cdot(1-0.47)^t[/tex]
[tex]C(t)=11\cdot0.53^t[/tex]

Takehiko brought grapes to school. He gave 15 of his grapes to his friends. If he is left with 45 grapes, how many did he bring to school? *
Answer: he took 60 grapes to school
Step-by-step explanation:
you just have to think about this. if you have given a friend 15 grapes and you are left with 45. So, for you to have 45 left you must have left home with 60 grapes.
Mathematically, lets represent how many he brought to school with x
15+45=x
X= 60

Step-by-step explanation:
Ms. Garcia is selling smoothies at the Flea Market. Yesterday, she sold 24
strawberry smoothies and 5 chocolate smoothies, for a profit of $200,
Today, she made a profit of $300 by selling 30 strawberry smoothies
and 11 chocolate smoothies. How much profit does Ms. Garcia earn from
each smoothie?
Answer:
The profit form a strawberry smoothie is of $26.32, and the profit from a chocolate smoothie is of $26.32.
Step-by-step explanation:
This question can be solved by a system of equations.
I am going to say that:
x is the profit from a strawberry smoothie.
y is the profit from a chocolate smoothie.
Se sold 24 strawberry smoothies and 5 chocolate smoothies, for a profit of $200.
This means that: 24x + 5y = 200
Today, she made a profit of $300 by selling 30 strawberry smoothies and 11 chocolate smoothies.
This means that 30x + 11y = 300
So we have the following system:
24x + 5y = 200
30x + 11y = 300
I will use the addition method, multiplying the first equation by 5 and the second by -4. So
120x + 25y = 1000
-120x - 44y = -1500
So, adding both equations, we get:
[tex]-19y = -500[/tex]
[tex]19y = 500[/tex]
[tex]y = \frac{500}{19}[/tex]
[tex]y = 26.32[/tex]
And for x:
[tex]24x = 200 - 5y[/tex]
[tex]24x = 200 - 5(26.32)[/tex]
[tex]24x = 68.4[/tex]
[tex]x = \frac{68.4}{24}[/tex]
[tex]x = 2.85[/tex]
The profit form a strawberry smoothie is of $26.32, and the profit from a chocolate smoothie is of $26.32.
