Starting At 1:00 Pm The Temperature Changes -4 Degrees Per Hour. How Long Will It Take To Reach -1 Degrees?

Answers

Answer 1
We know that the temperature to start off is 35, so in an equation y=mx+b with x representing the time in hours , m being the slope, and y being the temperature, when x=0 we have y=b, and since the temperature is 35 at the start, y=36=b, making our equation y=mx+35. Next, since we lose 4 degrees every hour, we have the slope, or the change in temperature every hour, equal to -4, making our equation y=-4x+35. We want to find out how long it will take for the temperature to reach -1 degrees, so we plug -1 in for y (temperature) to get -1=-4x+35. Subtracting 35 from both sides using the subtraction property of equality, we get -36=-4x. Next, we divide both sides by -4 to get 9=x=how many hours it will take to reach -1 degrees

Daniel's basic cell phone rate each month is $29.95. Add to that $5.95 for voice mail and $2.95 for text messaging. This past month Daniel spent an additional C dollars on long distance. His total bill was $62.35. How much did Daniel spend on long distance?

Answers

5.95 + 2.95 = 8.9
8.9 + 29.95 = 38.85
62.35 - 38.85 = 23.5 
So Daniel spent $23.50 on long distance calling 

Answer: Daniel spent $23.5 on long distance

Step-by-step explanation:

Hi, to answer this question we have to write an equation with the information given.

So, Daniel's total bill (62.35) is equal to the sum of the cost of all the services: Basic cell phone rate (29.95); voice mail (5.95); text messaging (2.95); long distance (C)

Mathematically speaking:

29.95+5.95+2.95+C = 62.35

Solving for C

38.85+C =62.35

C =62.35-38.85

C =$23.5

Daniel spent $23.5 on long distance

y=−13x+4y=−13x+4



Then plot two points to graph the equation.

Answers

Solution-

The given equation,

[tex]y=-13x+4[/tex]

Then, we have to calculate two points that satisfy the equation,

Calculating y for x = 0,

[tex]y(0)=-13(0)+4=4[/tex]

So, point (0, 4) satisfies the equation.

Calculating y for x = 1,

[tex]y(1)=-13(1)+4=-13+4=-9[/tex]

So, point (1, -9) satisfies the equation.

Answers

It would be the last set of data. You can tell this because when put in ascending order, 26 is the minimum and 38 is the maximum. Here, you find the median and then to find the first quartile and third quartile points, you find the median of the first half and the second half.

Q1= the half point between the minimum and the median

Q3= the half point between the median and the maximum.

By doing this, it should match up to the box and whisker plot

The dataset that can be used for box-and-whisker plot is 27, 35, 35, 32, 26, 34, 36, 27, 38.

What is the data set?

A box plot is used to study the distribution and level of a set of scores. The whiskers represent the minimum value and the maximum value.

On the box, the first line to the left represents the lower (first) quartile. The next line on the box represents the median. The third line on the box represents the upper (third) quartile.

Minimum value = 26

Maximum value = 38

Q1 = 27

Median = 34

Q3 = 35

there 12 beads on the bracelet. 8 of the beads are purple. what percent of the beads are purple

Answers

There are 12 beads on the bracelet and 8 of the beads are purple. What percent of the beads are purple?

The fraction [tex]\frac{8}{12}[/tex] represents the number of purple beads on the bracelet out of all the beads on the bracelet.

To find what percent of the beads are purple, we can turn the fraction [tex]\frac{8}{12}[/tex] to a percent.

We can first reduce the fraction [tex]\frac{8}{12}[/tex] by dividing both the numerator and denominator by the Greatest Common Factor of 8 and 12 using 4.

8 ÷ 4 = 2

12 ÷ 4 = 3

Our reduced fraction is [tex]\frac{2}{3}[/tex]

2 ÷ 3 = 0.66666666666667

0.66666666666667 × 100 = 66.666666666667%

Therefore, 66.666666666667% of the beads on the bracelet are purple.

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. The total number of blueberries that Lydia will need is 40 blueberries.

What is multiplication?

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.

Given that Lydia makes 10 pancakes she tops each pancake with blueberries. Therefore, the total number of blueberries that Lydia will need is,

Total number of blueberries

= Number of pancakes × Number of blueberries used on each pancake

= 10 pancakes × 4 blueberries per pancake

= 40 blueberries

As per the distribution strategy, we can draw 10 circles and then 4 mini circles on each circle to represent blueberries. Therefore, we can make the drawing as shown below.

Hence, the total number of blueberries that Lydia will need is 40 blueberries.

A city is paving a bike path. The same length of path is paved everyday. After 4 days, there are 8 miles of path remaining to be paved. After 6 more days, there are 5 miles of path remaining to be paved.

a. Explain how you know the situation can be modeled by a linear equation.

b. Write an equation that gives the distance (in miles) as a function of the number of days since the project began.

c. In how many more days will the entire path be paved?

Answers

Attached the solution with detailed work.

The linear equation is y = (-3/2)x + 14 and the number of days will be 10 days.

What is a linear equation?

It is described as the relationship between two variables, and a straight line results from plotting the graph of the linear equation.

The equation is referred to as a linear equation in one variable if just one variable is contained in the linear equation.

It is given that:

A city is paving a bike path.

The same length of the path is paved every day. After 4 days, there are 8 miles of path remaining to be paved.

After 6 more days, there are 5 miles of path remaining to be paved.

The coordinates are (4, 8) and (6, 5)

The linear equation can be modeled:

[y - 5]  = (5-8)/(6-4)[x-6]

y - 5 = -3/2[x - 6]

2y - 10 = -3x + 18

2y = -3x + 28

y = (-3/2)x + 14

Plug y = 0

(-3/2)x + 14 = 0

x = 28/3

x = 9.33 ≈ 10 days

Thus, the linear equation is y = (-3/2)x + 14 and the number of days will be 10 days.

As Mars revolves around the sun, it travels at a speed of approximately
15
miles per second. Convert this speed to miles per minute. At this speed, how many miles will Mars travel in
4
minutes? Do not round your answers.

Answers

Step 1: Multiply 15 and 60 that equals 900
Step 2: Now multiply 900 by 4 and that equals 3,600

So, Mars revolves around the sun 900 miles per minute. In four minutes mars would have traveled 3,600 miles every 4 minutes.

Final answer:

To convert Mars' speed from 15 miles per second to miles per minute, multiply by 60 to get 900 miles per minute. Multiplying this by 4 gives the distance Mars will travel in 4 minutes, which is 3600 miles.

Explanation:

As Mars revolves around the sun, it travels at a speed of approximately 15 miles per second. To convert this speed to miles per minute, you simply multiply by the number of seconds in a minute:

15 miles/second × 60 seconds/minute = 900 miles per minute.

At this speed, to find out how many miles Mars will travel in 4 minutes, you multiply Mars' speed in miles per minute by the number of minutes:

900 miles/minute × 4 minutes = 3600 miles.

Therefore, Mars will travel 3600 miles in 4 minutes at the speed of 15 miles per second.

A crack in a water main pipe leaks 7 gallons of water each hour. What volume of water has moved though the crack after 9 hours?

7 gallons of water 9 times is basically 7 * 9, or 63.
