Answer:

the answer would be 112.5min

Explanation:

I believe you have the equations wrong. 1 equation you can use is t=15d, and the other equation you can use is d=t/15. then if you plug 7.5 for d in one of the equations you can get the answer

Yes so well done for establishing
T= 30
And d=2
Now we need an equation that links together.
So to get d (2) equal to t (which is 30) we need to multiply by 15.
So t = 15d
Or if you make d the subject
D = 15/t

So if this Titus walks 7.5 miles
T = 15 x distance
Time = 15 x 7.5
So the time is 112.5
Hope it helps

A property's value decreased by 15%. If is was worth 189,000, what is worth now?

Answers

15% of 189000 = [tex] \frac{15}{100} \times 189000 = 28350 \\ [/tex]

So, now it's worth[tex] = 189,000 - 28,350 \\ = 160,650[/tex]

The current worth of the property is $160,650.

What is percentage?

Percentage, is a relative value indicating hundredth part of any quantity.

Formula for percent decrease

Percent decrease = ( decreased value/ original value) × 100

Therefore,

Decreased value = Original value - new value

According to the question

We have

Percent decrease = 15%

Original value of the property = $ 189,000

So, 15% 0f $189,000 = [tex]\frac{15}{100}[/tex] × 189000

⇒ 15% of 189000 = $28350

Therefore, the decreased value of the property = $189000 - $28350

Decreased value of property = $160,650

Hence, the current worth of the property is $160,650.

Answer:

3. m= -15

4. x= 9

Step-by-step explanation:

3. Cross multiply: -6m=90

Solve: m= -15

4. Cross multiply: 7x+7=10x-20

Solve: x=9

Step-by-step explanation:

Here,

-m=10*9/6

or,-m=90/60

or,-m=15

or,-m=-(-15)

and, m=-15

Here,

(x+1)*7=(x-2)*10

or,7x+7=10x-20

or,7+20=3x

Below is a graph of p, an insect population, w weeks after it was first measured. The population grows exponentially.

Write an approximate domain and range for this situation.
Write an equation relating p and w.

Answers

The range and the domain of the graph are the sets of non-negative real numbers, while the equation relating p and w is [tex]p = 300 * 3^w[/tex]

From the graph, we have the following ordered pairs

(1,900) and (3,8100)

An exponential function is represented as:

[tex]p = ab^w[/tex]

At the point (1,900), we have:

ab = 900

At the point (3,8100), we have:

ab^3 = 8100

Divide both equations

[tex]\frac{ab^3}{ab} = \frac{8100}{900}[/tex]

Evaluate the quotients

[tex]b^2 = 9[/tex]

Take the square roots of both sides

b = 3

Recall that:

ab = 900

So, we have:

3a = 900

Solve for a

a= 300

Hence, the equation is:

[tex]p = 300 * 3^w[/tex]

Max is already 224 miles into his road trip. If he is averaging 52 miles per hour and the trip is 640 miles total, how many more hours does he have left to drive?
x - hours left to drive

Answers

Answer:

8 hours.

Step-by-step explanation:

1. Subtract 640-224=416

2. Divide 416/52

3. 8 hours

Answer:

8 hours.

Step-by-step explanation:

We have been given that Max is averaging 52 miles per hour and the trip is 640 miles total. Max is already 224 miles into his road trip.

Let us find the remaining distance of trip by subtracting the distance already covered from total distance.

Remaining Distance = 640 miles - 224 miles

Remaining Distance = 416 miles

We will use formula: Time = Distance/Speed to find the number of hours Max still have to drive.

Time = 416 miles/52 miles/hour

Time = 416 miles/52 × hour/miles

Time = 416/52 hour

Time = 8 hours

Therefore, Max have left 8 more hours to drive.

Answer:

Given : points 4 , 1 ,25 , opposite of 3 , -1/2

Solution :

Numbers with a negative sign are less than zero

Right of zero represented by ‘+’ sign and to the left of zero represented by ‘–’ sign.

+ sign numbers can be denoted as simply numbers

On a number line the number increases as we move to the right and decreases as we move to the left.

1 : Draw a line and mark some points at equal distance on it as shown in the figure below Mark a point as zero on it. Points to the right of zero are positive integers and are marked simply 1, 2, 3 and so on , while points to the left of zero are negative integers and are marked – 1, – 2, – 3 and so on

2. Go 4 unit on right sides from Zero to show 4

Two vehicles start from the same point traveling in the same direction. One vehicle travels 55 miles per hour (mph) and the other 45 mph. When will the two vehicles be 350 miles apart?

Answers

Answer:

45 x + 55 x = 350

x increases until the total equals 350

45 + 55 = 100 = relative speed of approach

(B) traveling cars meet this equation's specifications (x = 3.5)

The correct statement is option B)

What is the speed of an object?

Speed is the rate at which an object's position changes, measured in meters per second. For example, if an object starts at the origin, and then moves three meters in three seconds, its speed is one meter per second. The equation for speed is simple: distance divided by time

Given here: The equation as 45x+55x=350

A car, traveling 45 mph, leaves Dallas heading for Odessa 350 miles away. At the same time, a truck leaves Odessa for Dallas traveling 55 mph on the same road.

Therefore the relative speed of the two trucks is given by 45+55=100

and let the time taken to meet is x then we can construct an equation as follows x=350/100

or, 45x+55x=350

Hence, The correct statement is option B)
