A mini bus can carry 8 students. How many mini buses will be needed to transport 38 students?
Answer:
5 buses
Step-by-step explanation:
you need to divide the number of students (38) by the number of students a mini bus can carry.
38 : 8 = 4.75
since they want to know how many buses will be needed to transport all students, you round 4.75 to 5
hope this helps!

Write an equation for the line that passes through (- 3, 5) and is parallel to y = - 6x + 1.
Answer:
y-5 = -6(x+3) OR y = -6x-13
Step-by-step explanation:
Let's use slope-intercept form to solve this problem.
Slope intercept form is the following:
y-y1 = m(x-x1)
x1 and y1 are given by the point in the problem.
x1 = -3, y1 = 5.
m is given by the equation in the problem. Lines that are parallel have the same slope. Thus,
m = -6.
If we plug these values into the equation for slope intercept form, we get the following:
y-5 = -6(x-(-3)) which becomes y-5 = -6(x+3)
This is an acceptable answer to the problem. However, point-slope form is also a way it can be written.
y-5 = -6x-18
y = -6x-13
Please help me ASAP.
Answer:
y=3x+10
Step-by-step explanation:
m=y2-y1/x2-x1
-5-7=(-12)
3-(-1)=4
-12/4=3
y=3x+b
7=3(-1)+b
3*-1=(-3)
-3(-3)=0
7-(-3)=10
b=10

2x=4y in standard form
Answer:
The answer is −2x+y=−4 or 2x−y=4 . Standard form is Ax+Ay=C
Step-by-step explanation:
Standard form is a way of writing down very large or very small numbers easily. 103 = 1000, so 4 × 103 = 4000 . So 4000 can be written as 4 × 10³ . This idea can be used to write even larger numbers down easily in standard form.

james went out for a long walk . He walked 3 2/5 of the mile. then he sat down to take rest . After that he walked 5/7 of a mile. how far did he walk together
Answer:
Altogether James walked [tex]4\frac{4}{35}[/tex] miles.
Step-by-step explanation:
The question involves mixed fractions. Mixed fractions are first converted into proper fractions and then any operation can be performed on them.
Given
Distance of first walk = [tex]3\frac{2}{5}[/tex] of a mile
Distance of second walk = 5/7
In order to find how much he walked altogether, we have to find the sum of both fractions.
[tex]Total\ distance = 3\frac{2}{5}+\frac{5}{7}\\= \frac{17}{5}+\frac{5}{7}\\=\frac{17*7}{5*7} + \frac{5*5}{7*5}\\=\frac{119}{35} + \frac{25}{35}\\=\frac{119+25}{35}\\=\frac{144}{35}\\=4\frac{4}{35}[/tex]
Hence,
Altogether James walked [tex]4\frac{4}{35}[/tex] miles.

A skating rink charges $4 for ice skate rental and a
fee of $3 for each hour of skating. Kelsey paid a total
of $10 to rent skates and to skate for n hours. What
is the value of n ?
What is the value of n
Answer:
N=2 hours
Step-by-step explanation:
She spent a total of 10 dollars.
Ice skate rental costs 4$
The fee per hour for skating is 3$ per hour
So minus 10$ by 4$, which is 6$
So now here at six and each fee per hour cost 3$, so therefore she skated for N= 2 hours.

An airplane flying with the wind takes 2 hours to travel a distance of 360 miles.
The return trip takes 3 hours flying against the wind.
What is the speed of the airplane in still air and how fast is the wind blowing?
Answer: still air is 150mph. The wind speed is 30mph.
Step-by-step explanation:
X=speed of the plane, Y=speed of the wind.
360/2hours=180
360/3hours=120
2x=180+120
2x=300
X=150
The airplane in still air is 150mph
Add together
X+y=180
150+y=180
Y=180-150
Y=30mph
The wind speed is 30mph

Find the equation of a line that passes through the point (2,-5) and is perpendicular to the y-axis. Do not put any spaces in your answer.
Answer:
y=-5
Step-by-step explanation:
Equation of the line
Lines can be expressed in several forms. The slope-intercept form of the line is:
y = mx + b
Where m is the slope of the line and m is the y-intercept.
If the line is perpendicular to the y-axis, then it's a horizontal line. Horizontal lines have slope m=0, thus, the equation is:
y = b
To find the value of b, just substitute the given point:
-5=b
The equation of the line is:
y=-5

Solving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define systems
y = 4x - 9
y = x - 3
Step 2: Solve for x
Substitute in y: 4x - 9 = x - 3Subtract x on both sides: 3x - 9 = -3Add 9 to both sides: 3x = 6Divide 3 on both sides: x = 2Step 3: Solve for y
Define: y = x - 3Substitute in x: y = 2 - 3Subtract: y = -1A town's population increases in one year from 50,000 to 62,000. If the population is growing linearly, at a steady rate, then what will the population be at the end of a second year?

32^(x+4) = 64^(2x-1)
Answer:
Vamos a resolver la ecuación paso a paso.
32x+4=642x−1
Step-by-step explanation:
Resolver el exponente.
32x+4=642x−1
log(32x+4)=log(642x−1)(Sacar el logaritmo de ambos lados.)
(x+4)*(log(32))=(2x−1)*(log(64))
x+4=(
log(64)
log(32)
)*(2x−1)
x+4=1.2*(2x−1)
x+4=2.4x−1.2(Simplificar ambos lados de la ecuación)
x+4−2.4x=2.4x−1.2−2.4x(Restar 2.4x a ambos lados)
−1.4x+4=−1.2
−1.4x+4−4=−1.2−4(Restar 4 a ambos lados)
−1.4x=−5.2
−1.4x

a mean of 3 out 5 students request for tomato sauce with their meal in a canteen.a random sample of 8 students is selected.what is the probability that less than 4 students request for tomato sauce with their meal
Answer:
this answer is you listen
by the Rishabh
Step-by-step explanation:
mean of 3 out of 5 students
x 3 and 5 product of means product of extreme 3 and 4 is product of means 5 and 8 is the product of extreme x and your answer is coming follow the Rishabh
The probability of less than 4 students asking for tomato sauce along with their meal would be:
0.738
Given that,
Mean of the students asking for tomato sauce = 3/5
No. of random samples collected = 8 students
Given that,
Less than 4 = 0, 1, 2, 3
Let x be the number of students who ask for tomato sauce with their meal.
So,
[tex]P(x < 4) = P(x = 0) + P(x = 1) + P(x = 2) + P(x = 3)[/tex]
P(x = o) = [tex]C^{0} _{8} ( 1 - 3/5)^8 = 0.0007[/tex]
P(x = 1) = [tex]C^{1} _{8} ( 3/5) (1 - 3/5)^7 = 0.0079[/tex]
P(x = 2) = [tex]C^{2} _{8} (3/5)^2 ( 1 - 3/5)^6 = 0.0413[/tex]
P(x = 3) = [tex]C^{3} _{8} (3/5)^2 ( 1 - 3/5)^5 = 0.1239[/tex]
Using binomial distribution,
[tex]P(x< 4) = 0.0007 + 0.0079 + 0.0413 + 0.1239[/tex]
[tex]= 0.738[/tex]
Thus, 0.738 is the correct answer.
