First, we have to find the t value in Jumel’s equation that will get him $75. So our equation is 75=60+0.05t. Then solve for your t value (subtract 60 from each side, divide by 0.05). You should get 300 as your t value. After this, just plug 300 into Ashley’s equation to find the cost. Your answer should be $150

Part C: Because both the equations are linear, both plans will cost the same at the point of intersection on a graph. This is where a certain t value for equation will produce the same c value, or cost

Paula caught a tarpon with a weight that was 11 times as great as the weight of a permit fish she caught. The total weight of the two fish was 168 pounds.
How much did each fish weigh?

The permit fish weighed ___
pounds.

The tarpon weighed ___
pounds.

Answers

Okay so let’s say the permit fish is the variable p.
The tarpon is 11p.

So, to set up the equation,
(11p)+p=168
Start by combining like terms on the left
12p=168
Divide both sides by 12 to isolate p
p=14
So therefore, the permit fish was 14 pounds.

To find the weight of the tarpon, insert the 14 back into (11p) 11(14)=154.

You can check by adding these together 14+154=168


So:
The permit fish weighed 14 pounds.

The tarpon weighed 154 pounds.

Answers

Answer:

24 students that have used a vaping product at least once

Step-by-step explanation:

Based on the scenario described we can say that the who in this study would be the 24 students that have used a vaping product at least once. That is because the entire study is focused around individuals who have used vaping products, therefore since only a select population were chosen to be part of the study we need to determine and target which of this selected sample of students have used vaping products and that will be the "who" in the study. Which in this scenario, are 24 students.

A) Antoine's family is taking a summer vacation through the northern united states on day one of the trips the family will be travelling 85 miles on day two of the trip they will travel 125 miles on the third day they will travel 176 miles how many kilometres will Antoine and his family travel each day? (calculate to the nearest kilometres.) b) How many miles and kilometres will they travel in total?

Answers

Answer:

621.207km

Step-by-step explanation:

We are expected to convert from miles to kilometer

first day 85 miles =136.794km

Second day 125 mile=201.168km

third day 176 miles =283.245km

Total distance covered is

136.794km+201.168km+283.245km=621.207km

Therefore the total distance in kilometer is 621.207km

The Allied Taxi Company charges $2.50 to pick up a passenger and then adds $1.95 per mile. Isaac was charged $27.46 to go from one city to another. If x represents the number of miles driven by the taxi, which linear equation can be used to solve this problem, and how many miles did Isaac travel, rounded to the nearest tenth? 1.95x + 2.50 = 27.46; Isaac traveled 15.4 miles. 1.95x + 2.50 = 27.46; Isaac traveled 12.8 miles. 2.50x + 1.95 = 27.46; Isaac traveled 11.8 miles. 2.50x + 1.95 = 27.46; Isaac traveled 10.2 miles.

Answers

Answer:

B. 1.95x + 2.50 = 27.46; Isaac traveled 12.8 miles.  

Step-by-step explanation:

If x represents the number of miles driven by the taxi  

Then, amount charged= $ (2.50+1.95x)  

Isaac was charged $27.46  

2.50+1.95x = 27.46  

Subtracting both sides by 2.50, we get  

1.95x= 24.96  

Dividing both sides by 1.95, we get  

x=12.8

The linear equation will be 1.95x + 2.50 = 27.46

Amount charged to pick up passenger = $2.50 to pick up a passenger

Amount charged per mile = $1.95 per mile

Since Isaac was charged $27.46, then the equation will be:

2.50 + 1.95(x) = 27.46

2.50 + 1.95x = 27.46

Therefore, the linear equation will be 1.95x + 2.50 = 27.46

In the morning a group of hikers hiked 3 ½ miles, took a break, and then hiked another 2 ¾ miles. The group then stopped for lunch. In the afternoon, the group the hiked 4 ¼ miles, and took another break. How many more miles do they need if the whole trail is 14 miles long?

Answer:

3 2/4

Step-by-step explanation:

1/2 is equivalent to 2/4 so you add 3 2/4 + 2 3/4 and that = 6 1/4 and its simple math from there on, 6 1/4 + 4 1/4 = 10 2/4 finally 14 - 10 2/4 = 3 2/4

5.5 miles are left to cover.

What is Unitary Method?

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

In the morning a group of hikers hiked 3 ½ miles

and then hiked another 2 ¾ miles. then group the hiked 4 ¼ miles.

Total miles to cover = 14 miles

So, number of miles to be driven

= 14 - ( 3 ½ + 2 ¾ + 4 ¼)

= 14 - ( 7/2 + 11/4 + 17/4)

= 14- (14/4 + 11/4 + 17/4)

= 64 - 42 / 4

= 22/4= 11/2

= 5.5 miles

Hence, 5.5 miles are left to cover.

The angle directly across from the 32 is also 32 degrees because it uses the same lines at the same angles. That's the Vertical Angles Theorem. The line straight across means that is 180 degrees, which is already split in half by the visible 90 degree angle (given by the box in the corner). Since all the angles are on the same side of the line, the 180 degree angle, they should add up to equal 180 degrees. Also, since 90 is half of 180, the 32 degree angle and the x angle should just add up to equal 90 degrees. So, 90 minus 32 equals 58.

Minimum salary is 250$. Rate of commission is 5.65% . Weekly sales are 1,515. Whats the gross pay

Answers

Minimum salary: $250
Sales: 1515
Commission: 5.65% x 1515 = $85.5975

Gross Salary: 250 + 85.5975 = $335.5975

The gross pay would be $335.5975.

What are Arithmetic operations?

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.

+ Addition operation: Adds values on either side of the operator.

For example 4 + 2 = 6

- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.

for example 4 -2 = 2

* Multiplication operation: Multiplies values on either side of the operator

For example 4*2 = 8

We have been given that the minimum salary is $250

Here Weekly sales = 1515

Total commission = 5.65% × 1515

Total commission = 5.65/100 × 1515

Total commission = $85.5975

To determine the gross pay

We have to add the minimum salary and total commission,

Gross Salary = 250 + 85.5975

Gross Salary = $335.5975

Therefore, the gross pay would be $335.5975.
