Answer:

D. Temperature(minutes), or t(m)

Step-by-step explanation:

Option D is the correct answer.

( D.temperature(minutes), or t(m) )

Step-by-step explanation:

We are given that:

The temperature of the coffee depends on the number of minutes it sits on the desk.

i.e. the temperature(t) of coffee is a function of time in minutes (t).

i.e. times is a independent variable and temperature is a dependent variable.

Hence, the most appropriate name for the function described below is:

temperature(minutes), or t(m).

Hence, option D is correct.

The sale price after both markdowns will be $336

<em><u>Explanation</u></em>

The selling price of an item is $600. After 6 months of not selling, it is marked down by 30%

So, the marked down amount after 6 months $=\$ 600*0.30= \$180$

and the selling price after first 6 months will be: $\$600-\$180=\$420$

After another 6 months of not selling , it is further marked down by 20%. So, the marked down amount now $= \$420*0.20=\$84$

Thus, the final selling price after all markdowns $=\$420-\$84=\$336$

Answer:

The length of the slide is 10 feet.

Step-by-step explanation:

To find the length of the slide you have to use the formula:

a^2 + b^2 = c^2 (^2 means squared)

In this case:

a= 6 and b=8 c= unknown

6 squared (6 times 6) is 36

8 squared (8 times 8) is 64

Add these two numbers to get:

36+64=100

6^2+8^2=100

However, the length of the slide in not 100 feet. In order to find the correct length you must find the square root of 100. Which is 10.

What number times itself equals 100? 10.

The length of the slide in 10 feet.

Why is there no commutative property for subtraction and division

Bezzdna [24]

There is no commutative property for subtraction and division because order does matter. 6 - 5 will not give you the same answer as 5 - 6.

Need help with this ignore what a put in the box it isn’t right

Zarrin [17]

$f=6cm\\g=8cm$

Why?

The first thing we need to do is find the area of the triangle, we can to that by subtracting the area of ABCD from ACBE, then, we can use the formulas to calculate the area for both triangle and rectangle to find "f" and "g".

Calculating we have:

$TriangleArea=ABCE-ABCD\\\\TriangleArea=60cm^{2}-48cm^{2}=12cm^{2}$

Now, we can calculate "f" by using the formula to calculate the area of the triangle:

$TriangleArea=\frac{b*h}{2}\\\\TriangleArea=\frac{f*4cm}{2}\\\\12cm^{2}*2=f*4cm\\\\\frac{24cm^{2}}{4cm}=f\\\\f=6cm$

Now, finding "g" by using the formula to calculate the area of the rectangle, we have:

$RectangleArea=ABCD\\\\ABCD=Base*Height\\\\48cm^{2}=base*6cm\\\\base=g=\frac{48cm^{2}}{6cm}=8cm$

Hence, we have that:

$f=6cm\\g=8cm$

Have a nice day!
