Dirk can clean a playground in 5 hours. Geralyn can clean a playground in only 4 hours. Which of the following can be used to determine the amount of time it would take for Dirk and Geralyn to clean a playground together?

Answer:

B: The independent variable influences change in the dependent variable whether the points on the scatterplot go up or down from left to right.

Step-by-step explanation:

edg2021

dependent means it depends on something, such as the independent variable that will change it

The independent variable influences the dependent variable in a scatterplot regardless of whether the relationship is positive (upward slope) or negative (downward slope), which is shown by the direction in which the points trend.

The correct statement is: The independent variable influences change in the dependent variable whether the points on the scatterplot go up or down from left to right. This means that the independent variable can have either a positive relationship or a negative relationship with the dependent variable. If there is a positive relationship, as the independent variable increases, the dependent variable also increases and vice versa. Conversely, in a negative relationship, as the independent variable increases, the dependent variable decreases, and as the independent variable decreases, the dependent variable increases. A scatterplot is a tool that helps visualize these relationships, with the independent variable typically plotted on the horizontal axis and the dependent variable on the vertical axis. The slope of the points in a scatterplot indicates the direction of the relationship, which can be assessed by observing whether most points lie around a line that slopes upwards or downwards.

Step-by-step explanation:

Alright, lets get started.

Please refer the diagram I have attached.

Let us suppose the sun has angle of elevation x

The triangle formed will be a right triangle, so

[tex]tan x= \frac{opposite}{adjacent}[/tex]

[tex]tanx = \frac{6}{8}[/tex]

taking tan inverse

[tex]x=tan^{-1}(\frac{6}{8} )[/tex]

[tex]x=36.87[/tex]

To the nearest degree, the angle will be 37 degrees.  :   Answer

Answer:
The complement of m∠WXV is m∠UXV

Explanation:

Complementary angles are two (or more) angles with a sum of 90 degrees.

Because line WT is dissected perpendicularly by line UX, two 90° angles are formed in ∠TXU and ∠WXU. We know that they are both 90° because of the box on ∠TXU. ∠TXU and ∠WXU are supplementary angles -- two angles that occupy the same line but are dissected by a perpendicular line forming two angles with a sum of 180 degrees.

If ∠TXU + ∠WXU = 180, and ∠TXU = 90, then ∠WXU must also equal 90:
90 + ∠WXU = 180
90 - 90 + ∠WXU = 180 - 90
0 + ∠WXU = 90
∠WXU = 90°

As we see in the diagram, ∠WXU is dissected by line SV. Because of this, it is broken into the two angles of ∠WXV and ∠UXV. We already established that ∠WXU is 90°. Therefore the sum of these two angles formed must equal 90°, which, in turn, means they are complementary angles. They complement one another.

Therefore, the complement of ∠WXV is ∠UXV

To find the total length of 120 watermelon seeds, each 4mm long, we just need to multiply the length of one seed by the total number of seeds. Then, to convert the total length from millimeters to meters, we divide by 1000. So, a line of 120 watermelon seeds would be 0.48 meters long.

This problem involves simple multiplication to solve it. Since each watermelon seed is 4mm long, to find the length of 120 seeds lined up, we just need to multiply 120 by 4. So, 120 seeds * 4mm/seed = 480mm. To convert millimeters to meters, we divide by 1000 (as there are 1000mm in a meter). So, 480mm = 0.48 meters. Therefore, a line of 120 watermelon seeds would stretch 0.48 meters.

Hello!

The answer should be the second option B.

Acceleration is a rate of change in velocity. It involves a change in speed and direction. Change of velocity over a period of time.

Acceleration formula

The equation that can be used to solve for acceleration is acceleration = (change in velocity)/time (Option B).

The equation that can be used to solve for acceleration is acceleration = (change in velocity)/time (Option B).

This equation calculates acceleration by dividing the change in velocity by the time taken.

For example, if an object's velocity changes from 10 m/s to 20 m/s in 5 seconds, the acceleration can be calculated using this equation as (20 m/s - 10 m/s) / 5 s = 2 m/s2.

Answer:

about 112 customers

Step-by-step explanation:

we know that

To find out  how many customers does the local shop serve in a day, multiply the fraction 2/9 by the number of customers that the shop run serve in a day

Let

x ----> the number of customers that the shop run serve in a day

y ----> the number of customers that the local shop serve in a day

[tex]y=\frac{2}{9}x[/tex]

we have

x=502

substitute the value of x in the equation

[tex]y=\frac{2}{9}(502)[/tex]

[tex]y=111.6[/tex]

Round up

so

about 112 customers

The local shop serves about 112 customers in a day

Order of Operations in Mathematics follow this following rule :

This rule is known as the PEMDAS method.

In working on a mathematical problem, we first calculate operation that is in parentheses, follow by exponentiation, then multiplication or division, and finally addition or subtraction.

Let us tackle the problem.

This problem is about Percentage.

A local coffee shop serves 2/9 as many customers as a shop run by a national coffee chain.

[tex]\texttt{Local Shop's customers} = \frac{2}{9} \times \texttt{National Chain's customers}[/tex]

Final answer:

To find out how much Beau and Belle must markdown the dress for Charlene to stay within her budget of $65, we use the inequality 76.48 - m ≤ 65, which solves to m ≥ 11.48, meaning the dress needs a markdown of at least $11.48.

Explanation:

To determine the markdown Beau and Belle must offer for Charlene to afford the dress within her budget, we can set up an inequality. Let's denote the markdown as m. The original price of the dress is $76.48, and Charlene's budget is $65. Therefore, the dress's price after the markdown should be less than or equal to $65. The inequality that models this scenario is:

76.48 - m ≤ 65

This inequality states that the original price of the dress minus the markdown m should be less than or equal to Charlene's budget of $65. To find out how much of a markdown is needed, we will solve for m.

Subtracting $76.48 from both sides of the inequality:

-m ≤ 65 - 76.48

-m ≤ -11.48 (This indicates that the markdown must be at least $11.48)

To express m as a positive number, we multiply both sides of the inequality by -1, remembering to reverse the inequality symbol:

m ≥ 11.48

Therefore, Beau and Belle must markdown the dress by at least $11.48 for Charlene to stay within her budget constraint.
