I assume the answer for question 2 is ≈$5.23

Explanation:
First, I subtracted the fee from the budget, since I don't believe the service fee is a part of each ticket.
542.94-45.82=497.12

Then, I divided the answer from the equation to the number of people that are going, since ticket costs would be even amongst the 90 people.
497.12/90≈5.52

C) A bus drives for 3/2 hours at an average speed of 56 mph. How far does the bus drive?

natta225 [31]

Answer:

The bus drives 84 miles

Step-by-step explanation:

The question relates to relationship between average speed and time

The given parameters are;

The time duration in which the bus drives = 3/2 hours = 1.5 hours

The average speed of the bus = 56 mph

The formula average speed is given as follows;

$Average \ speed = \dfrac{The \ total \ distance \ driven}{The \ time \ duration \ of \ travel}$

Therefore, we have;

The total distance driven = Average speed × The time duration of travel

The total distance driven = The distance the bus drives

Substituting the given values, gives;

The distance the bus drives = 56 miles/hour × 1.5 hours = 84 miles

The distance the bus drives = 84 miles.

A scientist measures the width of ten different tree branches in inches. The results were 18, 24, 27, 30, 21, 18, 24, 30, 30, an

arlik [135]

The mode is the number that occurs most frequently in the set.
Putting the numbers in order will help us find the mode.
18,18,21,24,24,24,27,30,30,30

We see that 24 and 30 have an equal number of occurrences in the data set, meaning that 24 and 30 are both modes.

Marine fuel is a combination of gasoline and motor oil. The standard gasoline and oil mixture is about 98% gasoline and about 2%

Georgia [21]

Answer:

0.98g+ 0.02m= 7.1224 gallons standard mixture

0.96g+ 0.04m= 6.25 gallons break oil

3.92 gallons of gasoline is required for 4 gallons the standard mixture

Step-by-step explanation:

If we have to use 6 gallons of gasoline this means that 98%= 6 gallons and 2% would be 6/98*2

Gasoline: Motor oil

6 : x

98 : 2

Using the product rule

x= 6*2/98= 0.1224 gallons of motor oil is required.

Let the gasoline be represented by g and motor oil by m then for the standard oil the equation would be

0.98g+ 0.02m= 7.1224 gallons standard mixture

For break in oil

Gasoline: Motor oil

6 : x

96 : 4

Using the product rule

x= 6*4/96= 0.25 gallons of motor oil is required.

Let the gasoline be represented by g and motor oil by m then for the break oil the equation would be

0.96g+ 0.04m= 6.25 gallons break oil

Part b. For 4 gallons of the "break in" mixture

96% of the 4 gallons of the "break in" mixture is gasoline = 3.84 gallons of gasoline

4% of 4 = 0.16 gallons of motor oil

Now the standard mixture 4 gallons would contain 98 % of gasoline and 2 % of motor oil

98% of 4 gallons= 3.92 gallons of gasoline

2% of 4 gallons= 0.08 gallons of motor oil.

Mrac [35]

Answer:

$0.6990$

Step-by-step explanation:

We have:

$log_{10} (10)=1$

$\therefore \log_{10}(2\times 5)=1$

$\implies \log_{10}(2)+ \log_{10}(5)=1$

$\implies \log_{10}(5)=1-\log_{10}(2)$

$\implies \log_{10}(5)=1-0.3010=\boxed{0.6990}$
