When would you write an x in an equation?)

mafiozo [28]

Answer:

$\Large \boxed{\mathrm{When \ a \ number \ is \ not \ known}}$

Step-by-step explanation:

For example, a sum of a number and 6 is 12.

The number is unknown.

Let the number be x.

x + 6 = 12

We can solve for x (unknown number). Subtract 6 from both sides of the equation.

x = 6

During a bake sale, 1 and 1/2 dozen cookies were sold in 1/3 hour. what is the unit rate for the dozens of cookies sold per hour

rosijanka [135]

Find the number of cookies:

$\text {Cookies = } 1 \dfrac{1}{2} \text { dozens}$

Since 1 dozen = 12:

$\text {Cookies = } 1 \dfrac{1}{2} \times 12$

Change to improper fraction:

$\text {Cookies = } \dfrac{3}{2} \times \dfrac{12}{1}$

Simplify:

$\text {Cookies = } 18$

18 cookies were sold in 1/3 hour:

$\dfrac{1}{3} \text { hour = } 18 \text { cookies}$

$\text {1 hour = } 18 \times 3 \text { cookies}$

$\text {1 hour = } 54 \text { cookies}$

------------------------------------------------------------------
Answer: Unit rate for cookies sold = 54/hour

A trapezoid pyramid has a base area of 128 square centimeters. If it’s volume is 10,240 cubic centimeters, what is the height of

White raven [17]

Answer:

The height of the pyramid is $1.875\ cm$

Step-by-step explanation:

we know that

The volume of the trapezoid pyramid is equal to

$V=Bh$

where

B is the area of the trapezoid base

h is the height of the pyramid

we have

$B=128\ cm^{2}$

$V=240\ cm^{3}$

substitute and solve for h

$240=(128)h$

$h=240/(128)=1.875\ cm$

Which statements best describe the dot plot or box plot ? Check all that apply.Need answer ASAP

zloy xaker [14]

<h3>The 2 answers are: A and D</h3>

==========================================

Explanations

A. True. This is because there are 13 dots shown. You cannot use the box plot to determine this.

B. False. This contradicts choice A above. Also, we cannot use the box plot to determine how many people there are. What 12-7 = 5 is showing is that the range is 5. This means the range for the age of runners is 5 years. In other words, 5 years is the span from the youngest (age 7) to the oldest (age 12).

C. False. The median is 10 as its shown in the box plot. Recall the median for any box and whisker plot is the vertical line inside the box.

D. True. The vertical line inside the box is the median. This vertical line does not have to be exactly halfway between the left and right edges of the box.

E. False. A box plot can be used to determine variability (in terms of range and IQR). You can determine the variability from a dot plot, though you'll have to do a bit of work to get it.

F. False. Refer to choice E.
