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

A local coffee shop serves 2/9 as many customers as a shop run by a national coffee chain. The shop run by the chain serves 502 customers day. About how many customers does the local shop serve in a day
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
Further explanationOrder of Operations in Mathematics follow this following rule :

Eva is jumping on a trampoline. Her height h at time t can be modeled by the equation h=-16t^2+20t+6. Would Eva reach a height of 14 feet?
A function assigns the value of each element of one set to the other specific element of another set. Eva can not reach a height of 14 feet.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
As the function of the height of the jump, Eva is given as h=-16t^2+20t+6. Now, in order to know if Eva will reach 14 feet height, we need to substitute the value of her height of Eva as 14 feet, therefore,
[tex]h=-16t^2+20t+6\\\\14=-16t^2+20t+6\\\\16t^2 - 20t+14-6=0\\\\16t^2 -20t + 8=0[/tex]
If we calculate the discriminant of the given quadratic equation, we will understand that the given quadratic equation has imaginary roots.
Therefore, Eva can not reach a height of 14 feet.

Find the area. The figure is not drawn to scale
Name the complementary to m
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

Suppose there is a relationship between independent and dependent variables represented by a scatterplot. Which statement is correct? The independent variable influences change in the dependent variable only if the points on the scatterplot go up from left to right. The independent variable influences change in the dependent variable whether the points on the scatterplot go up or down from left to right. The dependent variable influences change in the independent variable only if the points on the scatterplot go up from left to right. The dependent variable influences change in the independent variable whether the points on the scatterplot go up or down from left to right. Mark this and return
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.

watermelon seed is 4mm long. How far would a line of 120 watermelon seeds stretch? Write your answer in meters.
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.
Explanation: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.
