The temperature of a mixture was 12°Celsius at the start of the experiment. After four hours the temperature decreased 25°. What is the current temperature of the mixture?

Answers

Answer 1
12 - 25 is equal to -13.

Just think of it as 25 minus 12. This gives you 13. Then put a negative sign in front of it.

Assume that the cheetah travels an average of 40 mph to go from its resting place to a rock near a river. On the return trip to its resting place, the cheetah travels an average of 70 mph. If the cheetah traveled for 15 minutes, how many minutes did the return trip take to the nearest minute and second?
Set up the table as follows. Label the rows “To the River” and “From the River.” Label the columns “Distance,” “Rate,” and “Time (in Hours).” Let t represent the unknown quantity in the problem. Fill in the table.

Answers

Answer:

9.55 minutes

Step-by-step explanation:

x hours to go to the river

0.25-x hours to come back, since 15 minutes is 0.25 hr.

to the river 40 mph * x hours =40x miles

from the river 70 mph (0.25-x) hours=17.5-70x

those two are equal

40x=17.5-70x

110x=17.5

x=17.5/110=0.159 hours

Aaron needs to take out a loan to purchase a motorcycle. At one bank, he would
pay $2,500 initially and $150 each month for the loan. At another bank, he would pay
$3,000 initially and $125 each month. After how many months will the two loan
payments be the same?

Answers

Answer:

5 or 6 i think

Step-by-step explanation:

2500+150x=3000+125x solve for x and thats how many months it will be for the two loan payments to be the same.
150x-125x=25x 3000-2500=500 25x=500 500/25=20 25/25=1 x=20 20 months until the loan payments will be the same.

Answer:

B>-1 1/4

Step-by-step explanation:

The rational number is one tick mark to the right of -6/4 is [tex]-1\frac{1}{4}[/tex].

What is number line?

A straight line of numbers is shown visually as a number line. This line is used to compare integers on an endless line that extends on both sides, either horizontally or vertically, at equal intervals. On a horizontal number line, the numbers grow as we walk to the right and decrease as we move to the left.

Given the number -6/4,

if we go right of -6/4 it is moving towards -1

the points right to -6/4 are -5/4, -4/4,....

the next point right of -6/4 is -5/4

the mixed form of -5/4 is  [tex]-1\frac{1}{4}[/tex].

Hence option B is correct.

[tex]r=\frac{q-ps}{p}[/tex]

General Formulas and Concepts:

Order of Operations: BPEMDASEquality PropertiesDistributive Property

Step-by-step explanation:

Step 1: Define equation

[tex]q=p(r+s)[/tex]

Step 2: Solve for r

Distribute p:                              [tex]q=pr+ps[/tex]Subtract ps on both sides:       [tex]q-ps=pr[/tex]Divide both sides by p:            [tex]\frac{q-ps}{p} =r[/tex]Rewrite:                                     [tex]r=\frac{q-ps}{p}[/tex]

Step-by-step explanation: To solve for r, start by distributing the p

through the parentheses on the left side to get q = pr + ps.

Next, isolate the r term by subtracting ps from both sides to get -ps + q = pr.

Finally, to get r by itself, divide both sides by p and we have -ps + q/p = r.

The mesquite's roots are considered the longest of any desert plant and have been recorded as long as 80 feet.

Answer:

Long roots for desert plants look similar to other roots, only more lengthy. The roots spread out from the base of the plant deep into the earth. Typically, the roots are larger than regular thread roots so that they absorb more water.

Water boils at 100 degrees celsius or 212 degrees fahrenheit. Water freezes at 0 degrees celsius or 32 degrees fahrenheit. If the weather forecaster says it will be 25 degrees celsius today. write and solve a linear equation to find what fahrenheit temperature this is.

Answers

Answer:

given with two conditions: after 0 degrees Celsius, this is equal to 32 degrees Fahrenheit and after at 100 degrees Celsius, this is equal to 212 degrees Fahrenheit . We translate these into points, we have (0,32) and (100, 212). we get the slope of the points ((212-32)/100) or 9/5. we plug to the equation y-y1 = m (x-x1) where m is equal to 9/5. y-32 = 9/5 (x-0). Simplifying, we get y -32 = 9x/5 or equal to y = 9/5 x + 32 where x is degrees Celsius and y is degrees Fahrenheit.

The given temperature is required in Fahrenheit.

The required temperature is 77 degrees Fahrenheit.

Let the x axis denote Celsius

and y axis denote Fahrenheit

The ordered pairs are [tex](100,212)[/tex] and [tex](0,32)[/tex]

The equation of the line will be

[tex]y-212=\dfrac{32-212}{0-100}(x-100)\\\Rightarrow y-212=1.8(x-100)\\\Rightarrow y-212=1.8x-180\\\Rightarrow y=1.8x+32[/tex]

The temperature is 25 degrees Celsius so [tex]x=25[/tex]

[tex]y=1.8\times 25+32\\\Rightarrow y=77[/tex]

The required temperature is 77 degrees Fahrenheit.
