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 standard number cube with the numbers 1 through 6 is rolled. Find the probability of rolling a number greater than 5 .
1. 1 / 6
2. 1 / 3
3. 1 / 4
4. 2 / 3
The probability of rolling a number greater than 5 is 1/6.
What is probability?Probability is the ratio that shows the likelihood an event will occur or not from a given set of events.
We can find the probability of rolling a number greater than 5 below:The total number of faces that have a number greater than 5 = 6.
The total number of faces = 6.
Therefore, the probability of that can be found as shown below:
P( rolling a number greater than 5 ) = The total number of faces that have a number greater than 5/The total number of faces
= 1/6
We have found the probability.
Therefore, we have found that the probability of rolling a number greater than 5 is 1/6.

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 :

Two people start walking at the same time in the same direction. One person walks at 8 mph and the other person walks at 2 mph. In how many hours will they be 4.5 miles apart?
Final answer:
Two people walking at 8 mph and 2 mph, respectively, will be 4.5 miles apart in 0.75 hours, or 45 minutes, because they are moving apart at a relative speed of 6 mph.
Explanation:
To calculate the time it will take for two people walking at different speeds to be 4.5 miles apart, we need to find the relative speed at which they are moving apart. The first person walks at 8 miles per hour (mph), and the second person walks at 2 mph. The relative speed is the difference in their speeds, which is 6 mph (8 mph - 2 mph).
We know that they want to be 4.5 miles apart. To find the time (t), we use the formula distance = speed × time, or rearranged to solve for time, time = distance / speed. Plugging in our values we get time = 4.5 miles / 6 mph, which simplifies to 0.75 hours. Therefore, it will take them 0.75 hours or 45 minutes to be 4.5 miles apart.

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.

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.

Radius=3 m
Height=13 m
[tex]\text{Surface area of cylinder is }\\\\=2\pi r(r+h)\\\\=2\times\frac{22}{7}\times3(3+13)\\\\=\frac{132}{7}(16)=301,71\sim302\thinspace m^2[/tex]
