Given:
mass of cat ( m ) = 10 kgAcceleration ( a ) = 10 m/s²To find out:
If it runs into a wall what force will be exerted by the cat?
Formula used:
Force = mass × acceleration
Solution:
Force = mass × acceleration
Now, Putting these values of m and a in the above equation.
we get:
F = 10 × 10
= 100 N
Thus, the force will be exerted by the cat is 100 N.
The force exerted by the cat when it runs into a wall can be calculated using Newton's Second Law of Motion, resulting in a force of 100 Newtons.
Explanation:The subject of this question pertains to the concept of Newton's Second Law of Motion, which states that the force applied to an object is equal to the mass of the object multiplied by its acceleration. Here, the cat is considered the object in motion. The cat's mass is 10kg, and its acceleration is given as 10 m/s².
By substituting these values into Newton's second law (Force = mass x acceleration), we can calculate the force exerted by the cat as it runs against a wall: Force = 10kg x 10 m/s² = 100 N (Newtons). Therefore, the cat will exert a force of 100 Newtons when it runs into the wall.

THE TABLE SHOWS THE AGES OF THE SWIMMERS ON DION'S SWIM TEAM.THE MEAN AGE OF THE SWIMMERS IS 10.WHAT DOES THE MEAN REPRESENT
Answer:
The mean is the balancing point of the swimmers' ages.
Step-by-step explanation:
I just took the I-Ready Quiz and got it correct. :D
The mean in mathematics refers to the average of a set of given numbers. Mean is commonly referred to as average.
Mean is the average number, which is calculated by the formula:
[tex]\rm mean = \dfrac{sum\; of\; all\; the\; given\; numbers}{\text{total observation}}[/tex]
For instance, the mean age of swimmers is 10, which means that the average age of all the swimmers is 10. The age of each swimmer can be near to 10, as 9, 10, 11, or 12.
Given the ages of swimmers are:
[tex]\text{mean} = \dfrac{10 + 10 + 11 + 9}{4}\\\text{mean} = \dfrac{40}{4}[/tex]
mean = 10
Thus, the mean of the given data is 10.

Step-by-step explanation:
A sample of students is taken from the school's A honor roll. The school estimates that there are actually 360 students on the A honor roll. Using this sample, how many students on the A honor roll are 8th graders?
By multiplying the individual probabilities of being a music student and being on the honor roll and then multiplying by the total on the honor roll, we find the expected number of music students on the honor roll to be 16.
Explanation:To determine the expected number of music students who are also on the honor roll, we can use the concept of expected value in probability.
Assuming that being a music student and being on the honor roll are independent events, we can multiply the probability of a student being a music student by the probability of a student being on the honor roll.
The probability of randomly selecting a music student from the 300 students is the number of music students divided by the total number of students, P(Music) = 50/300.
The probability of a student being on the honor roll is P(Honor Roll) = 97/300. So, the expected number of music students on the honor roll would be the product of these two probabilities times the total number of students on the honor roll, which the school estimates to be 360.
The calculation: Expected number = [tex]P(Music) \(\times\) P(Honor Roll) \(\times\) Total Honor Roll = (50/300) \(\times\) (97/300) \(\times\)[/tex]

A sports store I'd having a sale on soccer balls. A soccer coach purchases 10 soccer balls and 2 soccers bags for $155. Another scorer coach purchases 12 soccer balls and 3 soccer bags for $189. What is the cost of a soccer ball and the cost of a soccer ball ?
Answer:
- The price of a soccer ball is $14.5
- The price of a soccer bag is $5
Step-by-step explanation:
To solve this problem, we call:
s = the price of a single soccer ball
b = the price of a soccer bag
We have:
1) A soccer coach purchases 10 soccer balls and 2 soccers bags for $155: so we can write
[tex]10s+2b=155[/tex] (1)
2) Another scorer coach purchases 12 soccer balls and 3 soccer bags for $189: so we can write
[tex]12s+3b=189[/tex] (2)
So we have a system of two equations in two unknown variables:
[tex]10s+2b=155\\12s+3b=189[/tex]
We solve it by multiplying eq.(1) by 3 and eq(2) by 2, and we get:
[tex]30s+6b=465\\24s+6b=378[/tex]
Now we substract eq(2) from eq(1) and we get:
[tex]6s=87[/tex]
So
[tex]s=\frac{87}{6}=14.5[/tex]
And by using eq(1) we also find the value of b:
[tex]10s+2b=155\\b=\frac{155-10s}{2}=\frac{155-10(14.5)}{2}=5[/tex]
So:
- The price of a soccer ball is $14.5
- The price of a soccer bag is $5
To solve this problem, we can set up a system of equations and use the elimination method to find the values of x and y. The cost of a soccer ball is $14.5 and the cost of a soccer bag is $5.
Explanation:To solve this problem, we can set up a system of equations. Let's use x to represent the cost of a soccer ball and y to represent the cost of a soccer bag.
From the first equation, we have 10x + 2y = 155. From the second equation, we have 12x + 3y = 189.
We can solve this system of equations using substitution or elimination method. I will use the elimination method.
Now we can substitute the value of x into one of the equations to find the value of y.
Therefore, the cost of a soccer ball is $14.5 and the cost of a soccer bag is $5.
How far is point E(5,3) from the origin ?
Answer:
It is 5.84 units away from the origin.
Step-by-step explanation:
[tex]d = \sqrt{ {(x2 - x1)}^{2} + {(y2 - y1)}^{2}} [/tex]
Therefore:
[tex]d = \sqrt{ {(5 - 0)}^{2} + {(3 - 0)}^{2} } \\ d = \sqrt{ {5}^{2} + {3}^{2} } = \sqrt{25 + 9} \\ d = \sqrt{34} = 5.83951...[/tex]
Final answer:
The distance from point E(5,3) to the origin is calculated using the Pythagorean theorem, resulting in \/34 units.
Explanation:
The question asks how far point E(5,3) is from the origin. To find the distance between a point and the origin in a Cartesian coordinate system, we use the Pythagorean theorem. Specifically, the distance ( extit{d}) can be calculated using the formula extit{d} = \/((x_2 - x_1)² + (y_2 - y_1)²), where ( extit{x_1}, extit{y_1}) represents the coordinates of the first point (in this case, the origin (0,0)) and ( extit{x_2}, extit{y_2}) represents the coordinates of the second point (in this case, point E(5,3)).
Plugging in the values, we get extit{d} = \/((5 - 0)² + (3 - 0)²) = \/(5² + 3²) = \/(25 + 9) = \/34. The exact distance between point E and the origin is \/34 units, which can also be approximated as a decimal if necessary.

a) Write a polynomial for the perimeter of this shape. Simplify the polynomial. (The polynomial is in the photo)
b) Determine the perimeter of the shape when d = 5 m.
Answer:
a) 4d + 18
b) 38 inches
Step-by-step explanation:
a) The perimeter is simply the sum of all the exterior side lengths.
On the top, we've got d and d + 3.
On the left side, we have 2 and an unknown. However, we do know that this "unknown" + 2 will be the same length as the right side, which is 6. So, we have 2 + unknown = 6; hence, the unknown = 4.
The bottom is the same length as the top two lengths, so it's:
d + (d + 3) = 2d + 3
And, the right side is 6.
Adding these together, we have:
d + (d + 3) + 2 + 4 + d + (d + 3) + 6 = 4d + 18
b) We just need to substitute 5 in for d:
4d + 18
4 * 5 + 18 = 20 + 18 = 38 inches

2. Write the equation of the line of best fit using the slope-intercept formula y = mx + b. Show all your work, including the points used to determine the slope and how the equation was determined.
3. What does the slope of the line represent within the context of your graph? What does the y-intercept represent?
Answer:
2) y = x + 2
3) slope: height increases by 1 unit per unit increase in x
Intercept: initial height (at birth) was 2 units
Step-by-step explanation:
Using (38,40) and (48,50)
Slope: (50-40)/(48-38)
= 10/10
= 1
y = mx + b
y = x + b
40 = 38 + b
b = 2
y = x + 2
Answer:
see below
Step-by-step explanation:
There are (60,61) and (20,23) are the points that I used to find the slope for the line of best fit
m= (y2-y1)/(x2-x1)
m = (23-61)/(20-60)
= -38/-40
= .95
We use the slope intercept form of the equation
y= mx+b
y = .95x+b
Substituting in the point (20,23)
23 = .95(20) +b
23 = 19+b
Subtracting 19 from each side
23-19 = 19+b-19
4 =b
The equation is
y =.95x+4
The slope is how much y changes for each change in x. You did not tell us what the units of x and y are.
The y intercept is what the y value is when x is zero. The y value is 4 when x is zero

To solve the equations, subtract the given number from the sum on the left side of the equation to find the missing number. For the arithmetic expression, perform the operations in order.
Explanation:In the first equation, you must find a number that, when added to 9, equals 10. To do this, subtract 9 from 10, which gives you 1. Therefore, the missing number is 1.
In the second equation, you need to find a number that, when added to 1, equals 10. Subtract 1 from 10 to get 9. So, the missing number is 9.
In the last equation, you simply need to perform the arithmetic operations in order: 200 + 500 = 700, 700 + 2000 = 2700, and finally 2700 - 3000 = -300. Therefore, the result of the expression 200 + 500 + 2000 - 3000 is -300.

The point A has coordinates A(2, 4). What are the coordinates of A′ for the dilation D1.5(A)?
Answer:
[tex]A'(3,6)[/tex]
Step-by-step explanation:
The given coordinate is [tex]A(2,4)[/tex].
It's important to know that a dilation implies a bigger figure than the original. In this case, we have a factor of dilation of 1.5, which means each coordinate must be multiplied by it.
So, using the factor of dilation, we have
[tex]A(2,4) \implies A'(3,6)[/tex]
Because [tex]2 \times 1.5 = 3[/tex] and [tex]4 \times 1.5 = 6[/tex]
Therefore, the right answer is [tex]A'(3,6)[/tex]
The coordinates of [tex]\( A' \)[/tex] after dilating point [tex]\( A(2, 4) \)[/tex] by a factor of [tex]\( 1.5 \)[/tex] are [tex]\( {(3, 6)} \)[/tex].
To find the coordinates of [tex]\( A' \)[/tex] after dilating point [tex]\( A(2, 4) \)[/tex] by a scale factor of [tex]\( 1.5 \)[/tex], we use the formula for dilation:
If [tex]\( A'(x', y') \)[/tex] is the image of [tex]\( A(x, y) \)[/tex] under dilation with scale factor [tex]\( k \)[/tex], then:
[tex]\[ x' = k \times x \][/tex]
[tex]\[ y' = k \times y \][/tex]
Given:
[tex]\( A(2, 4) \)[/tex]
Scale factor [tex]\( k = 1.5 \)[/tex]
Now, calculate the coordinates of [tex]\( A' \)[/tex]:
[tex]\[ x' = 1.5 \times 2 = 3 \][/tex]
[tex]\[ y' = 1.5 \times 4 = 6 \][/tex]

Answer:
C = 73
Step-by-step explanation:
Formula used: a²+b²=c²
A and B represent the numbers other than the hypotenuse, so C equals the hypotenuse. It doesn't matter which number you put as A or B. Here's the equation we're working with:
(55)² + (48)² = C²
That simplifies to:
3025 + 2305 =C²
5329 = C²
Now, C needs to be by itself in order for us to get the answer, so the next step is to do inverse operations. The inverse of sqauring a number (x²) is to square root it (√x). Here is the new equation we are working with:
√5329 = √C
That simplifies to:
73 = C

The price of a gallon of apple cider is $7.00 the price of eight 4.23 ounces juice boxes is $2.39 suppose the cider was instead packets like the juice in boxes approximately what is the cost per eight 4.23 ounce boxes of cider
Answer:
$1.85
Step-by-step explanation:
$7.00 is the price of 1 gallon of apple cider
Step 1
The first step would be to find how many ounces make a gallon
And 1 gallon of apple cider juice = 128 ounces
Therefore,
$7.00 makes 128 ounces of apple cider juice
Step 2
The second step is to find how many ounces make 1 packet or package boxes
Eight 4.23 ounces juice boxes = 1 packet
Therefore, 8 × 4.23 ounces = 33.84 ounces.
Step 3
To find cost per eight 4.23 ounce boxes of cider which is the cost per 33.84 ounces,
We used the proportion below.
If 128 ounces = $7
33.84 ounces = Y( we call this y because it is unknown)
We cross multiply
128 ounces × Y = $7 × 33.84 ounces
Y =($7 × 33.84 ounces) ÷ 128 ounces
Y = $1.85
Therefore, 33.84 ounces which is would cost us $1.85.
Therefore, the cost is $1.85 per eight 4.23 ounce boxes of cider.

Rowan has two pieces of cable, one 15 feet long and the other 12 feet long. For a science project he wants to cut them up to produces pieces of cable that are all the same length, with no cable left over. What is the greatest length, in feet, that he can make them?
Answer:
The greatest length she can cut to have equal length in all the cables, without a left over is 3 feet each
Step-by-step explanation:
in order to solve this, we treat the length of each cable as separate numbers for which we find the highest common factor, since we are told that they must all be of the same length. The highest common factor of two whole numbers, is the highest number which completely divides both number without a remainder. The highest common factor is found as follows:
Factors of 12 are : 1, 2, 3, 4, 6, and 12
factors of 15 are : 1, 3, 5, and 15
from the above, the highest factor that is common to both numbers is 3.
Therefore, if both cables are cut into 3 feet each, , a total of 9 pieces of cables (4 from the 12 feet cable and 5 from the 15 feet cable) of equal length will be obtained without any remainder.
Answer:
3 feet
Step-by-step explanation:
To solve this problem the heed to find the factors of 15 and 12
Factors of both numbers
12 : 1,2,3,4,6,12
15: :1.3,5,15
Then we find the highest common factor between them which is 3, 3 is a factor of both 12 and 15
remainder. The highest common factor is found as follows:
So, if both cables are cut into 3 feet each, you should have a total of 9 piecesa total of 9 pieces of cables.
From the 12 feet long cable you should have 3 feet x 4 meaning 4 pieces
From the 15 fert long cable you should have 3 feet x5 meaning 5 pieces
4+5 makes it 9 pieces without any remainder

A cartoon last is one 1/2 of an hour. A movie is 6 times longer than the cartoon. How many minutes does it take to watch both the cartoon and the movie? (1hour = 60 minutes)
Final answer:
The cartoon lasts 30 minutes, and the movie is six times longer, adding up to 210 minutes to watch both.
Explanation:
The subject at hand is the duration it takes to watch a cartoon and a movie. The cartoon lasts half an hour (30 minutes), while the movie is six times longer than the cartoon. To find the duration of the movie, we multiply its relative length by the duration of the cartoon. So, 6 times 30 minutes is 180 minutes. To calculate the total time to watch both the cartoon and the movie, we add the two durations together. Therefore, 30 minutes for the cartoon plus 180 minutes for the movie equals 210 minutes in total.
