How many buses do you need for 600 people if each bus holds 65 people?
Answers
Answer:
You would need 10 buses
Step-by-step explanation:
To find the amount of buses needed, you just divide the total amount of people, and the capacity of each bus.
600/65
This would get you 9.23076923077, but obviously you can't have .23076923077 of a bus and you can't leave people behind. This means you would have to round the number up to 10

Select all the expressions that are equivalent to 24x + 12.
2(12x + 6)
–6(–4x – 2)
–3(8x – 4)
12(1 + 2x)
–4(–6 – 3x)
Answers
Answer:
2(12x + 6)
-6(-4x - 2)
12(1 + 2x)
The expressions that are equivalent to 24x + 12 are:
2(12x + 6)
-6(-4x - 2)
12(1 + 2x)
Let's go through each expression and simplify them to determine if they are equivalent to 24x + 12.
2(12x + 6):
We can use the distributive property to simplify this expression:
2 * 12x + 2 * 6 = 24x + 12
This expression is equivalent to 24x + 12.
–6(–4x – 2):
Again, using the distributive property, we simplify:
–6 * –4x + –6 * –2 = 24x + 12
This expression is equivalent to 24x + 12.
–3(8x – 4):
Once again, applying the distributive property:
–3 * 8x + –3 * –4 = –24x + 12
This expression is not equivalent to 24x + 12.
12(1 + 2x):
Using the distributive property:
12 * 1 + 12 * 2x = 12 + 24x = 24x + 12
This expression is equivalent to 24x + 12.
–4(–6 – 3x):
Applying the distributive property:
–4 * –6 + –4 * –3x = 24 + 12x = 12x + 24
This expression is not equivalent to 24x + 12.

Jim invests $1240 at a 3.6 interest rate in an account that is compounded quarterly. What is the value of the account after 6 years
Answers
Answer:
$1507.84
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 3.6%/100 = 0.036 per year,
then, solving our equation
I = 1240 × 0.036 × 6 = 267.84
I = $ 267.84
The simple interest accumulated
on a principal of $ 1,240.00
at a rate of 3.6% per year
for 6 years is $ 267.84.

What will be the perimeter and the area of the rectangle below if it is enlarged using a scale factor of 6.5? (5 points)
A rectangle is shown. The length of the rectangle is labeled as 8 cm, and the width is labeled as 6 cm.
Perimeter = 54 cm, area = 181.25 cm2
Perimeter = 54 cm, area = 2,028 cm2
Perimeter = 182 cm, area = 2,028 cm2
Perimeter = 182 cm, area = 181.25 cm2
Answers
Answer:
Perimeter = 182 cm, area = 2,028 cm2
Step-by-step explanation:
original perimeter=2*(8+6)+28 cm
original area=8*6= 48 cm²
You would have to do the old length and width times the scale factor
Multiply both of the width's
8 * 6.5 = 52 cm
scale factor: 6 * 6.5 = 39 cm
To get perimeter = 2(length + width)
2(52+39)=182 cm.
So you would have to do length(52 cm) * width(39 cm)
To get 2028 cm^2

A plane that carries mail makes a round trip each day from Chicago to New York. It makes 1 intermediate stop on the way to New York and 1 intermediate stop on the way back to Chicago. Suppose you make a graph of the altitude of the plane for one day, with time on the horizontal axis and altitude on the vertical axis. How many times will the graph touch the horizontal axis?
A. 5
B. 4
C. 7
D. 2
Answers
Answer:
C. 7
Step-by-step explanation:
The graph that is drawn here shows the altitude as a function of time. When the plane takes off from Chicago, the graph will start from the horizontal axis.
Next, when the plane takes 3 intermediate stops, altitude will touch the horizontal axis 3 times.
Next, when the plane lands in New York the altitude will touch the horizontal axis.
Next, when plane takes off from New York and takes an intermediate stop, altitude will touch horizontal axis.
Lastly the altitude will touch the axis when plane lands back in Chicago.
So, cumulatively the altitude will touch the horizontal axis seven times.
