Response:  A 21 cm candle burns for 12 hours.

Detailed explanation:

Equation illustrating the proportional relationship between two variables x and y

: \dfrac{x_1}{y_1}=\dfrac{x_2}{y_2}

Referring to the circumstances presented:

Let x_1=14\ cm,\ y_1=8\ hours,\ x_21\ cm,\ y_2=y

After substituting these values into the equation, we find

\dfrac{14}{8}=\dfrac{21}{y}\\\\\Rightarrow\ y=\dfrac{21\times8}{14}=12\ hours

Consequently,the 21 cm candle burns for 12 hours.

On a coordinate plane, a dashed straight line has a positive slope and goes through (negative 3, 1) and (0, 3). Everything to th
Svet_ta [9500]

Answer:

y>\frac{2}{3}x+3

Step-by-step explanation:

Step 1

Calculate the slope of the dashed line

The slope between two points is computed with the formula:

m=\frac{y2-y1}{x2-x1}

We consider

(-3,1) and (0,3)

and substitute into it:

m=\frac{3-1}{0+3}

m=\frac{2}{3}

Step 2

Determine the equation of the dashed line in slope-intercept form:

y=mx+b

The equation we established is:

m=\frac{2}{3}

b=3 ---> associated problem

Substituting yields:

y=\frac{2}{3}x+3

Step 3

Establish the inequality corresponding to the graph

Given that it is represented by a dashed line, the area to the left of this line is shaded.

Thus,

y>\frac{2}{3}x+3

Refer to the attached diagram for enhanced understanding of the problem.

Jenna works in an ice cream shop. When she starts her shift the tub of chocolate ice cream is 23 full. When she finishes her shi
tester [8842]

Answer:

Rate = 1.1/hr

Step-by-step explanation:

Given

Start = 23

End = 16

Hours = 6\frac{1}{2}h

Required

Calculate the hourly rate

First, we will determine the amount of ice cream that was sold

Ice\ Cream = 23 - 16

Ice\ Cream = 7

Next, calculate the average hourly rate:

Rate = Ice\ Cream/Hours

Rate = 7/6\frac{1}{2}h

Rate = 7/\frac{13}{2}h

Rate = 7*\frac{2}{13h}

Rate = \frac{14}{13h}

Rate = 1.07692307692/hr

Rate = 1.1/hr -- Approximated

C. -31m⁴n - 8m²Step-by-step explanation:Given:(9mn - 19m⁴n) - (8m² + 12m⁴n + 9mn)Required:Identify an equivalent expression for itSolution:Distributing the negative sign across the parentheses results in:9mn - 19m⁴n - 8m² - 12m⁴n - 9mnNext, we combine like terms:9mn - 9mn - 19m⁴n - 12m⁴n - 8m²This simplifies to -31m⁴n - 8m²Thus, -31m⁴n - 8m² is the equivalent expression for (9mn - 19m⁴n) - (8m² + 12m⁴n + 9mn).

AnnZ [9099]

Answer:

According to my cupcake recipe, it yields $12$ cupcakes and calls for $1\frac{1}{2}$ sticks of butter. I can only purchase whole sticks of butter.

Consequently, a single whole stick of butter will suffice to prepare $100$ cupcakes.
