On a flight,
3/10
of the passengers were children. There were
60 children on the flight. How many passengers were on
the plane?
Answer:
There were 200 passengers on the plane.
Step-by-step explanation:
1. 3/10 of the passengers were children -> 30% of the passengers were children
2. 60 children on the flight 30% of passengers = 60 people
divide by 3 -> 10% of passengers = 20 people
multiply by 10 -> 100% of passengers = 200 people.

Answer:
B, C, E
Step-by-step explanation:
Distributing the minus sign in the given expression results in ...
6x +1 -3x -(-1)
6x +1 -3 +1 . . . . simplify
The two expressions that show the constant terms as +1 - 1 are erroneous. The two constant terms are +1 -(-1) or +1 +1.
The correct expressions are the 2nd, 3rd, and 5th ones (b, c, e).

y + 12 = 41
Answer:
y=29
Step-by-step explanation:
y+12 - 12 = 41 -12
y=29
Answer:
y = 29
Step-by-step explanation:
subtract 12 on both sides to isolate & solve for y:
y + 12 = 41
- 12 -12
=> y = 41 - 12
=> y = 29
How many solutions does this system of equations have? Explain how you know.
Answer:
No solution
Step-by-step explanation:
The given equations are :
9x-3y=-6
3x-y=2.....(1)
5y=15x+10
5y-15x=10
or
y-3x=2 .....(2)
Equations (1) and (2) shows that the lines are parallel. We know that for parallel lines, there is no solution.
<2 and <4 are corresponding angles
m<4 = 17x° and m<2 = (9x+40)º
Find x and the measure of each angle.
Answer:
X = 5 u
m∠4 = 85º
m∠ = 85º
Step-by-step explanation:
17x = 9x + 40
17x-9x = 40
8x = 40
x = 40/8
x = 5
m∠4 = (17x)º = (17*5)º = 85º
m∠ = (9x+40)º = (9*5 + 40)º = (45 + 40)º = 85º

If you can buy 48 plaintains for $24 then how many can you buy with $4 ?
Answer:
8 plantains
Step-by-step explanation:
48=$24
x=. $4
192=24x , x= 192÷24= 8
Answer:
8 plantains
Step-by-step explanation:
Cost and number of plantains are in proportion
Number of plantains that can be bought for $ 4 be 'x'
48 : 24 :: x : 4
Product of means = product of extremes
24 * x = 48*4
[tex]x = \frac{48*4}{24}[/tex]
x = 2 * 4
x = 8

Lou deposited $1500 in a savings account. The
interest rate was 6.75% annually. How much
interest will he earn in 5 years?
And please add how you did it
Answer:
$506.25
Explanation:
assuming it is simple interest,
$1500 × 6.75% = $101.25 (interest earned each year)
$101.25 × 5 = $506.25 (interest earned in 5 years)

Amir can run 15 kilometers in one hour. How many kilometers can Amir run per minute? There are 60 minutes in 1 hour.
The answer is .25 kilometers a minute.
This is because [tex]speed = \frac{distance}{time}[/tex] so you need substitute then divide to find the answer
You can check this answer by doing 15÷60 which comes out to .25 km a minute.
Answer:0.25m per minute
Step-by-step explanation:
You divided the 15 by the 60 since 15 is the km and 60 minutes and you want to know how far can she run in minutes

What is the sum of 50.249 + 21.3
Answer:
71.549
Step-by-step explanation:
Answer:
The sum of 50.249 + 21.3 is 71.549.
Step-by-step explanation:
50.249 + 21.3 can be written as (50 + 20) + (0 + 1) + (0.2 + 0.3) + 0.049, which makes calculating the sum easier. 50 + 20 = 70, 0 + 1 = 1, 0.2 + 0.3 = 0.5, and you still have a 0.049. Add the numbers all together and you'll get that the sum of 50.249 and 21.3 is 70 + 1 + 0.5 + 0.049 or 71.549.

What is the value (Shown in the picture) of f(81)?
An airplane takes off at a speed S of 226 mph at an angle of 18° with the horizontal. Resolve the vector S into components.
Velocity=226mph
Angle made with horizontal= 18°
The vector components would be [tex] 226~sin18° \hat{j} + 226~cos18° \hat{i} [/tex]
The vector components of Speed is [tex]\rm v_x[/tex] = 226 cos 18° and [tex]\rm v_y[/tex] = 226 sin 18°
What is a Vector ?
An parameter that has both magnitude and direction is called a vector.
It is given that
Speed S = 226 mph
Angle = 18 degree with the horizontal
The vector component are
[tex]\rm v_x , v_y[/tex]
here these are x and y components of the vector
V is the magnitude = |v| = 226
The vector component is given by
cos [tex]\rm \theta[/tex] = [tex]\rm v_x[/tex] / |v|
[tex]\rm v_x[/tex] = 226 cos 18°
[tex]\rm v_y[/tex] = 226 sin 18°
Therefore the vector components of Speed is [tex]\rm v_x[/tex] = 226 cos 18° and [tex]\rm v_y[/tex] = 226 sin 18°

Answer:
Value of x = 87°
Step-by-step explanation:
Given:
∠1 = 102°
∠2 = x + 15°
Find:
Value of x
Computation:
We know that, given two lines are parallel and third line interest that
So,
Corresponding angles are equal
So,
∠1 = ∠2
x + 15 = 102
x = 87
Value of x = 87°
One day last summer, Tommy decided to take a drive into the countryside.
After a few hours' drive he arrived at a farm stand. Tommy was so excited by the sight of all those fresh fruits and veggies, that he tripped getting out of his MG and knocked over a huge basket of eggs. And of course they all broke!
He asked the farmer how many eggs were in the basket because he obviously wanted to compensate her for them. She said she didn't know exactly.
"But I do know,' she said, "that this morning I decided the eggs would be easier to sell if they weren't in a big basket but if they were in little paper bags.
"So when I took all my eggs and placed two in each bag I had one left over. I didn't like that so I took the eggs and I put three in each bag. And when I did that, I also had one left over.
"When I put four in each bag, I had one left over. When I put five in a bag or six in a bag, I had one left over. And when I put seven in a bag, I had none left over."
So here's the question: what's the smallest number of eggs that Tommy should have to pay for?
9514 1404 393
Answer:
301
Step-by-step explanation:
In order for the remainder to be 1 when the number is divided by 2, 3, 4, 5, or 6, it must be 1 more than a common multiple of those numbers. The least common multiple is ...
3·4·5 = 60
So, we want a number that is 1 more than a multiple of 60 and is divisible by 7. This gives us the Diophantine equation ...
7m -60n = 1 . . . . . where m and n are integers
Perhaps the easiest way to solve this is to try values of n between 0 and 6. We find that n=5 and m=43 will be the smallest positive value of m that satisfies this equation. This makes the number of eggs be 7×43 = 301.
Tommy should have to pay for 301 eggs.

Solve the system of equations by graphing. Look at the picture. Will Mark Brainliest
Answer:
See below
Step-by-step explanation:
Graphing:we are given two functions
[tex] \displaystyle \begin{cases}f(x) = - x + 5 \\ g(x) = {x}^{2} - 3x + 2\end{cases}[/tex]
where f(x) is a linear function and g(x) is a quadratic function
we want to figure out the solutions of the function
let's graph f(x):
the Black-table is attached
let's graph g(x):
the picture is attached
hence, the graph should be
the graph is attached
solutions stating:so we need solution(s) which satisfy(ies) the both functions
in this case the solution (s) the x coordinate(s) where both functions intercept we get from the graph that both functions intercept at (-1,6) and (3,2)
hence,
x={-1,3}
