Step-by-step explanation:

Use PEMDAS

1. (2x2)+2

You do 2x2 first which is 4 so then you do 4+2 which is 6

2. 6 divided by (5-3)

You do 5-3 first which is 2 then 6/2 (that's 6 divided by 2) which is 3

3. 6/6 x5

so you do 6 divided by 6 which is 1 then you get 1x5 which is 5.

4. 2-(5-4)

5-4 is 1 and 2-1 is 1

5. 2+6/6

6 divided by 6 is 1 and 2+1 is 3

6. (-6)+5 is -1

7.  1-(-7) is the same as 1+7 which is 8

8. (-3)-7 is the same as -3+7 which is the same as 7-3 which is 4

9. 5+(-2) is the same as 5-2 which is 3

10. 8-(-8) is the same as 8+8 which is 16

Terrence walks at a pace of 2 mi/h to the theater and watches a movie for 2 h and 15 min. He rides back home, taking the same route, on the bus that travels at a rate of 40 mi/h. The entire trip takes 3.5 h. How far along this route is Terrence’s house from the theater? Explain.

Answers

Answer:

2.2 miles

Step-by-step explanation:

3 hours and 30 minutes minus 2 hours and 15 minutes is 1 hour and 15 minutes. 2/40 gives you 0.05. 1.15 - 0.05 gives you 1 hour and 10 minutes and multiply that by 2 and it gives you 2.2 miles.

The distance between Terrence’s house from the theater will be 2.4 miles.

What is speed?

Speed is defined as the ratio of the time distance traveled by the body to the time taken by the body to cover the distance. Distance is defined as the length between the two points.

Let us suppose the following parameters to get the distance.

D = distance of Terrence’s house from the theater

v₁ = speed at which Terrence walks from home to the theater = 2 mi/h

t₁ = time taken by Terrence to walk from home to the theater = D/v₁ = D/2

v₂ = speed at which Terrence returns back to home = 40 mi/h

t₂ = time taken by Terrence to return back to home = D/v₂ = D/40

t' = time spent in watching the movie = 2 h 15 min = 2.25 h

t = total time = 3.5 h

The distance will be calculated as given below:-

t = t₁ + t₂ + t'

3.5 = (D/2) + (D/40) + 2.25

D = 2.4 miles

Emma buys produce for her dad’s French fry restaurant. She bought 55 bags of potatoes. There were 175 potatoes in each bag. How many potatoes did Emma buy? Susan solved the problem and said, “Emma purchased 1,750 potatoes for her dad’s restaurant.”

Answers

Answer:

9,625

Step-by-step explanation:

No. of potatoes present in each bag = 175

No. of bags of potatoes Emma brought = 55

So total no. of potatoes = 175 × 55

                                        = 9,625

Answers

Answer:

3/2

Step-by-step explanation:

Given the equation 3/2(4x-2)-3x = 5-(x+2)

Open the parenthesis

3/2(4x) - 3/2(2) -3x = 5-x-2

6x-3-3x = 3-x

3x-3 = 3-x

Collect like terms

3x+x = 3+3

4x = 6

Divide both sides by

4x/4 = 6/4

x = 3/2

Hence the value of x is 3/2

1. To determine simple interest, we use the formula i=prt where i is the interest, p is the principal or initial amount, r is the interst rate and t is the time. Sometimes it can be tricky to know what value to use when calculating t. A. What would you plug into the simple interest formula for t if you were given a time of 3 years? B. What would you plug into the simple interest formula for t if you were given a time of 4 months? C. What would you plug into the simple interest formula for t if you were given a time of 45 days?

Answers

Step-by-step explanation:

To determine simple interest, we use the formula

[tex]I=Prt[/tex]

where I is the interest, p is the principal or initial amount, r is the interest rate is in the unit of years and t is the time in years

When the times is 3 years , then we plug in 3 for 't' directly

[tex]I=Pr(3)\\[/tex]

we know that 1 year = 12 months

Suppose, the time is given in months then we divide time 't' by 12

When the times is 4 months , then we plug in 4 for 't' and divide by 12

[tex]I=\frac{Pr(4)}{12}[/tex]

we know that 1 year = 365 days

Suppose, the time is given in days then we divide time 't' by 365

When the times is 45 days , then we plug in 45 for 't' and divide by 365

[tex]I=\frac{Pr(45)}{365}[/tex]

You are baking and run out of an important ingredient. Rather than fire up the car, you decide to use a bicycle. The store is 1/2 mile away. Assume your car gets 30 miles to the gallon. If every driver on the planet made a similar decision once per week for a year, approximately how much gas would be saved for that year

Answers

Answer:

approximately 1.213 billion gallons of fuel will be saved per year.

Step-by-step explanation:

Distance to the store = 1/2 mile

If my car gets 30 miles to one gallons, then for 1/2 mile my car will use

1/2 ÷ 30 = 1/2 x 1/30 = 1/60 gallons

Statistics puts the number of cars users on Earth to be about 1.4 billion = 1.4 x 10^9 cars

If every driver makes this decision once a week for a year, that will be 52 times a year since there are 52 week in a year.

Total gas that will be saved in one week = 1/60 x 1.4 x 10^9 = 23333333.3 gallons

In a year that will be = 23333333.3 gallons x 52 = 1.213 x 10^9 gallons

that is approximately 1.213 billion gallons of fuel saved per year

Two trains leave the station at the same time, one heading east and the other west. The eastbound train travels at 90
miles per hour. The westbound train travels at 80 miles per hour. How long will it take for the two trains to be 408 miles
apart?
Do not do any rounding.

Answers

x = # of hours

80x + 90x = 408

Combine like terms.

170x = 408

Divide both sides by 408

x = 2.4 hours

It will take the trains 2.4 hours to be 408 miles apart.

The two trains will travel their 408-mile distance in around 2.4 hours.

To determine the time it will take for the two trains to be 408 miles apart, we can use the concept of relative motion.

Since the two trains are moving away from each other in opposite directions,

their speeds are added to calculate the rate at which the distance between them is increasing.

Let's consider the time it takes for the trains to be 408 miles apart:

Distance = Rate × Time

For the eastbound train:

Distance = 90 miles/hour × Time

For the westbound train:

Distance = 80 miles/hour × Time

Since the trains are moving away from each other, their distances traveled add up to the total distance between them:

90 miles/hour × Time + 80 miles/hour × Time = 408 miles

Combining like terms:

170 miles/hour × Time = 408 miles

To solve for Time, isolate it by dividing both sides of the equation by 170 miles/hour:

Time = 408 miles / 170 miles/hour

Now we can calculate the time:

Time = 2.4 hours

Therefore, it will take approximately 2.4 hours for the two trains to be 408 miles apart.

Rock climbing. I am out rock climbing, and the rock face has 4 easy, 7 challenging, and 3 extreme routes to get to the top. The routes are poorly marked, so I just choose one at random, with all routes equally likely. What is the probability that I do not choose an extreme route

Answers

Answer:

0.7857

Step-by-step explanation:

Given the following :

Number of Easy faces = 4

Number of challenging faces = 7

Number of extreme faces = 3

Total number of faces or route = (4 + 7 + 3) = 14

If one route is chosen at random, the probability of not choosing an extreme route will be :

Probability = (required outcome / Total possible outcomes)

P(not choosing an extreme route) = 1 - P(choosing an extreme route)

P(choosing an extreme route) = 3 / 14 = 0. 2143

Hence,

P(not choosing an extreme route) = 1 - 0.2143

= 0.7857
