Answer:
12 students
Step-by-step explanation:
First, find the percentage of how many students have siblings:
3/10 = 0.3 = 30%
40 * 0.3 = 12
This means that 30% of this class are 12 students. These 12 students have siblings.

If 4 gallons of milk cost $16.24, how much would 7 gallon of milk cost
Answer:
$28.42
Step-by-step explanation:
First let's calculate the cost per gallon.
We can do this by simply dividing the cost of 4 gallons by 4
1 gallon of milk cost 16.24/4 = 4.06
We want to find the cost of 7 gallons.
We can easily do this by multiplying the cost of one gallon by 7
7 gallons of milk cost 7 * 4.06 = $28.42

can someone help me please, this is so stressful:/
Answer:
x=2
Step-by-step explanation:
To solve for x, you want to isolate it. To do this, move terms that are NOT x and use the opposite operation to get it to the other side.
10x - 3 = 17
(Add 3 to both sides)
10x = 20
Now isolate x (since 10x is really 10 * x, you divide)
10x=20
x=2
This is how you would solve to get the solution.
Hope this helps :D
Given f(x)=2x+1 and g(x)=7-x. Find g(f(x)).
Answer:
f(g(x)) = 2(7 - x) + 1
Step-by-step explanation:
f(x) = 2x + 1
g(x) = 7 - x
The question in the picture itself says to find f(g(x)) so i'll find that instead
f(g(x)) = 2(7 - x) + 1
f(g(x)) = 14 - 2x + 1
f(g(x)) = -2x + 15

Can anyone help me with this please I really need help with this rq .
Answer:
Step-by-step explanation:
g(x) = ax - b
-76 = 27a - b
-79 = 28a - b Subtract
3 = -a Multiply both sides by -1
a = -3
g(x) = -3x - b
-85 = -3*30 - b
-85 = - 90 - b Add 90 to both sides
90-85 = - b Combine
5 = - b Multiply both sides by - 1
-5 = b
g(x) = -3x - b
g(x) = -3x - (-5)
g(x) = - 3x + 5

11. Commercial jets fly between 30,000 ft and 36,000 ft. About how many hours of growing could
pass before the beanstalk might interfere with commercial aircrafts? Explain how you got your
answer
An exponential function is a function that increases rapidly as the time increases.
The number of hours that passes before the magical beanstalk interferes with commercial flight is approximately 9.384 hours.Reasons:
The function that gives the height of a beanstalk is presented as follows;
b(t) = [tex]3^t[/tex]
When the height is 30,000 ft., we have;
30,000 = [tex]3^t[/tex]
㏑(30,000) = t·㏑(3)
[tex]\displaystyle t = \mathbf{\frac{ln(30,000)}{ln(3)}} \approx 9.384[/tex]
The time it would take the beanstalk to grow 30,000 ft., t ≈ 9.384 hours
Similarly, the time it would take the beanstalk to grow to 36,000 ft. is found as follows;
[tex]\displaystyle t_{36,000} = \mathbf{\frac{ln(36,000)}{ln(3)}} \approx 9.55[/tex]
The time it would take the beanstalk to grow 36,000 ft., t ≈ 9.55 hours
The number of hours it will take the beanstalk to grow to 30,000 feet at
which it might interfere with commercial aircrafts is 9.384 hours.

Determine which of the lines, if any, are parallel or perpendicular.

Step-by-step explanation:
ma=3,mb=_1/3, mc=3a and c are parallelb aree perpendicular to a and cThe organizers of a conference needs to prepare at least 200 notepads for the event
and have a budget of $160 for the notepads. A store sells notepads in packages of 24
and packages of 6.
24x + 6y > 200
This system of inequalities represent these constraints:
(16x + 5.40y = 160
The system of inequalities represent these constraints is 24x + 6y > 200 and 16x + 5.40y ≤ 160
Inequalities shows the non equal comparison of numbers or expressions.
Let x represent the number of packages of 24 notepads and y represent the number of packages of 6 notepads
Since the organizers need to do at least 200 notepads, hence:
24x + 6y > 200
Also, they have a budget of $160. Let us assume that each 24 package cost $16 and each 6 package cost $5.40, hence:
16x + 5.40y ≤ 160
The system of inequalities represent these constraints is 24x + 6y > 200 and 16x + 5.40y ≤ 160
