The formula for distance traveled d is d=rt, where r is the average speed of the object and t is time traveled. If an object travels 30 meters in 20 seconds, what is its speed
Answer:
Step-by-step explanation:
Distance formula:
d = rt
where d = distance, r = average speed and t = time travelled.
They told us that an object travels 30 meters in 20 seconds.
So we can say d = 30 and t = 20
If you put these values back into the distance formula you get:
d = rt
30 = r times 20
30 = 20 r
So now we want to find what "r" (average speed) is.
Divide both sides by 20.
20 r = 30
r = [tex]\frac{30}{20}[/tex] = 1.5 meters per second.
Limits do not give the y-value AT the given x; rather they give what y-values the function is __________ AROUND the given x
Using limits, it is found that the correct statement is:
they give what y-values the function is AROUND the given x.
What is a limit?The limit of a function f(x) as a value of x = a is approached is given by:
[tex]y = \lim_{x \rightarrow a} f(x)[/tex]
The limit can be calculated at a point in which a function is not continuous, for example, in which we consider the lateral limits, which is not the exact value at x = a, but the value of the function as x approaches a by the left and by the right, hence the correct statement is:
they give what y-values the function is AROUND the given x.

Captain Perguin bought 150 crackers for his
pet parrot. He ate 10% of them himself. How
many crackers did Captain Perguin eat?
Answer:
15
Step-by-step explanation:
Percentages represent a proportion of a number. This means that a percentage represents part of a whole.
In this question, Captain Perguin ate 10% of 150 crackers. There are 2 ways to solve this problem explained below.
Multiplication
One way to find a percentage is through multiplication.
First, convert the percentage into a decimal. Do this by moving the decimal point 2 places to the left. This means that 10% becomes 0.1Next, multiply this decimal by the whole number. Then, multiply [tex]150*0.1=15[/tex].This means that Captain Perguin ate 15 crackers.Shortcut
Multiplication is not the only way to find the answer. This question is special because it asks for 10%. Instead of multiplication, you could simply move the decimal point of the original number 1 digit to the left. This means that 10% of 150 must be 15. Remember this trick does not work for percentages other than 10%.

Help I need this done today !!!!
Answer:
c
Step-by-step explanation:
To find the maximum point, differentiate:
D' = -8p +160
Set to zero and solve for p:
D' = 0
⇒ -8p +160 = 0
⇒ 8p = 160
⇒ p = 20
Input p = 20 into the original equation to find D:
D = -4(20)² + 160(20) -310 = 1290
Therefore, the price is $20 and the maximum number of drills is 1,290

Suzie babysits for $6 per hour. She also works as a housecleaner for $9 per hour. She is only allowed to work 15 hours per week. She wants to make at least $95 per week. If we call babysitting, x, and housecleaning, y, which of the solutions would fit this scenario?
Answer:
x+y≤15
6x+9y≥95
Step-by-step explanation:
Let x be the hours worked for babysitting and let y be the hours worked for house cleaning.
As Suzie babysits for $6 per hour. She also works as a house cleaner for $9 per hour.
Total hours she can work= 15 hours per week.
Hence,
x + y is less than or equals to 15
But since she wants to make at least $95 per week. It implies that,
6x + 9y is greater than or equal to 95
So from the statements above, the equations will be:
x+y≤15
6x+9y≥95

Which linear inequality is represented by the graph? y > 2x 3 y < 2x 3 y > −2x 3 y < −2x 3
The equation represents the inequality will be y < −2x + 3.Option d is correct.
What is linear inequality?Linear inequalities involve at least one linear algebraic expression. A polynomial of degree 1 is compared to another algebraic expression of degree less than or equal to 1.
Different types of linear inequalities can be represented in a variety of ways.

The inequalities are as follows;
(a). y > 2x +3
(b). y < 2x+ 3
(c). y > −2x+ 3
(d). y < −2x+ 3
Because the line meets the y-axis,(0,3)the y-intercept is 3.
The points are (0,3)and(1,1)
The line's slope may be calculated as follows.
[tex]\rm m= \frac{1-3}{1-0} \\\\ \rm m= -2[/tex]
On putting the given origin value;
[tex]y < -2x+3 \\\\0 < -2(0)+3\\\\0 < 3[/tex]

Find the domain and range of the function represented by the graph
Step-by-step explanation:
Work and answer shown above
The Domain is -4 ≤ x ≤ 2
Range = 2 ≤ y ≤ 6
We have given a graph of a function. We have to find the domain and the range of the function
The domain refers to the set of all valid input values for a function. It represents the values for which the function is defined or meaningful. In other words, it is the set of x-values that can be plugged into the function to obtain a corresponding y-value.
The range, on the other hand, refers to the set of all possible output values or y-values that result from evaluating the function with the input values from the domain. It represents the set of all values that the function can attain.
As we can see from the graph
value of x is greater than and equal -4 and less than and equals 2
Domain = -4 ≤ x ≤ 2
Value of y is grater than and equal to 2 and less than and equal to 6
Range = 2 ≤ y ≤ 6

Terri and Kay are stocking cereal boxes in a middle aisle for a store display.
Together, they stocked 60 cereal boxes on the display. Kay stocked 8 more than of the 1/3 boxes that Terri
stocked. Which system of equations can be used to determine the number of cereal boxes Terri stocked
and the number of cereal boxes Kay stocked for the store display?
Let x represent the number of boxes Terri stocked and y represent the number of boxes Kay stocked.
Answer:
x = 26
y = 34
Step-by-step explanation:
Let the boxes stocked by Terri = x
Therefore the boxes stocked by Kay = x + 8 because he stocked 8 more boxes
Hence since they both stocked 60 boxes
x+x+8 = 60
2x = 60 - 8
2x = 52
divide both sides by 2
x = 26
Terri stocked 26 boxes and Kay stocked 26+8 boxes = 34 boxes

Answer:
y= 16, 64, 256, 1024
y/x= 16/2, 64/3, 256/4, 1024/5,
Step-by-step explanation:
This is just like any other equation, except instead of x being a number, it is an exponent. For example, when x equals 2, y equals 16 because y always equals four to the power of x. This applies to all of the parts in your table. when x equals 3, y equals 4^3 (4 times 4 times 4) which is 64, and when x equals 4, y equals 4^4 (4 times 4 times 4 times 4), which is 256.
For the y over x part that is just the value y, divided by the value x. For the first line on the table x equals 2, and we know y equals 16 (4^2 is 4 times 4, which is 16) so 16 divided by 2 is 8. That is the answer.
Hope this helps :)
