A salt water solution is cooled to −6° C. During an experiment, the mixture is heated so that its temperature rises at a steady rate. Write an equation to represent the temperature, y, after x minutes.

Answers

Answer:

y = -6 + xt

where t is the rate of rising of the heated mixture per minute

Step-by-step explanation:

From the question, we are lacking an important input. This is the value of the steady rise in temperature. In other terms, this is the rate at which the temperature of the mixture rises per minute.

Let this constant rate be t ° C. What this means is that it rises by this temperature in a minute.

in 1 minute, the temperature rise is t, in two minutes it will be 2t.

Then in x minutes, it will be xt

So adding the initial temperature of minus 6, the equation will be;

y = -6 + xt

An underground mine elevator descends 12% of the total depth every minute. The total depth of the elevator is 75 meters below the ground. How many meters below the ground is the elevator after 2 minutes?

Answers

Answer:

18m below the ground

Step-by-step explanation:

"An underground mine elevator descends 12% of the total depth every minute. The total depth of the elevator is 75 meters below the ground. How many meters below the ground is the elevator after 2 minutes?"

We want to estimate the depth after certain number of time

Given

total depth=75m

rate of descends =12% of total depth

= 12/100*75= 0.12*75

=9 meters per minute

Therefore in 2 minutes we can use the expression to find the distance/depth

speed= distance/time

9=distance/2

distance=9*2

distance= 18 meters

Therefore the elevator is 18m below the ground in 2 minutes

Answer:

18 meters

The fifth-grade students at Hawthorne Elementary School made an art project using two shapes of pasta. The students used 9 times as many elbow noodles as bowtie noodles. They used a total of 3,230 pieces of pasta. How many bowtie noodles did the students use?

Answers

Answer:

2,907 pieces of bowtie noodles was used by the student

Step-by-step explanation:

Here, we want to calculate the number of pieces of bowtie noodles use

Let the number of elbow noodles used be x

The number of bow tie noodles used is 9 times this and that will be 9 * x = 9x

Adding both together, we have 9x + x = 10x

Thus;

10x = 3230

x = 3230/10

x = 323 pieces

The number of pieces of bowtie noodles used will be 323 * 9 = 2,907 pieces

The sum of a number x and 7 is at least 16

A parent invests $2000 at a 5% interest rate to help his daughter save for college. How long will it take his money to double?

Answers

Answer: 20 years

Step-by-step explanation:

Principal = $2000

Rate = 5%

Interest = $2000

Time = Unknown

Since we want to know the time it will take his money to double, that means he'll have an interest of $2000.

Interest= PRT/100

2000 = (2000 × 5 × T)/100

2000 = 10000T/100

Cross multiply

2000 × 100 = 10000T

200,000 = 10000T

T = 200,000/10,000

Time = 20 years

In the diagram below, which distance represents the distance from point Q to
RS?

Answers

Answer: QT

Step-by-step explanation: This is because line QT is a straight line, in which it leads from point Q to line RS. QT is true because any other lines have angles, which add more (inaccurate) distance.

The required representation of distance from point Q to RS is QT.

What is a line?

A line is a straight distance connecting two points or more showing the shortest distance between the initial and final points.

here,
A figure is shown with a line segment RS and a point is located some distance from line RS, denoted as Q. It is to be determined which represents the distance from point Q to RS.

The shortest distance between a point and a line is the perpendicular line drawn from the point to the line, so QT is the representation of the measure of the distance from point Q to RS.

Thus, the required representation of distance from point Q to RS is QT.

Which statements about the trend line in Item 3 are true?
Select all that apply.
A. The slope is the cost of one book.
В.
The slope is the cost of Hana's lunch.
C.
The y-intercept is the cost of one book.
D.
The y-intercept is the cost of Hana's lunch.

Answers

Answer:

A and D

Step-by-step explanation:

I took it and I got it correct

The true statements are the slope is the cost of one book and the y-intercept is the cost if Hana's lunch​.

What is Slope?

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

Given:

As, from the graph the slope tells us about the  cost of one book.

Now, From the graph if we talk about y- axis then we can see that the y- axis tells us about cost if Hana's lunch​.

Hence, the true statements are the slope is the cost of one book and the y-intercept is the cost if Hana's lunch​.

Brylee has hiked 125 feet and hikes 1 foot per second. Jeremiah has hiked 10 feet and hikes 3.5 feet per second. After how many seconds will Brylee and Jeremiah have hiked the same amount of feet?

Answers

Answer:

46 seconds

Step-by-step explanation:

Brylee has hiked 125 feet and hikes 1 foot per second.

125 + s

Jeremiah has hiked 10 feet and hikes 3.5 feet per second.

10 + 3.5s

Where

s = number of seconds

Equate both Brylee and Jeremiah expression

125 + s = 10 + 3.5s

Collect like terms

125 - 10 = 3.5s - s

115 = 2.5s

Divide both sides by 2.5

s = 115 / 2.5

= 46

s = 46 seconds
