Answer:
402 cm.
Step-by-step explanation:
To find this, we will need to calculate the circumference of the reel. We can do this using the formula \(C = d\pi\).
Since the radius is 4 cm, the diameter is 8 cm. Put this into the equation to solve for the circumference:
\(C = 8\pi = 25.12\)
Since the reel spun 16 times, simply multiply the circumference by 16 to get:
25.12 × 16 = 401.92
≈ 402 cm.

Find the measure of x:
Answer:
x = 12
Step-by-step explanation:
(6x + 7) = (8x - 17)
Add 17 on both sides
6x + 24 = 8x
Subtract 6x on both sides
24 = 2x
Divide 2 on both sides
12 = x

Answer:
A = 8, B = 6, C = 4 , D = 7
Top = 29
Side = 20
Step-by-step explanation:
Last row : A + A + A + A = 32 ==> A = 8
First row : D + A + D + D = 3D + 8 = 29
3D = 21 ==> D = 7
Second row : B + D + A + B = 27 ==> 2B + 7 + 8 = 27
2B = 12 ==> B = 6
Third column : D + A + C + A = 27
7 + 8 + C + 8 = 27 ==> C = 4

find the answer using scientific notation
Answer: 2,000,000 or 2*10^6
Step-by-step explanation:
10*10^9 = 10000000000
5*10^3 = 5000
10000000000/5000=2000000
\(10x10^9\) = 10 x 1000000000 = 10,000,000,000
5 x 10^3 = 5 x 10 x 10 x 10 = 5,000
Divide 10 x 10^9 / 5 x 10^3 and the answer is
2 x 10^6

Elsa and Anna are running a race. Elsa is running at a rate of 2 meters per second and Anna is running at a rate of 1.75 meters per second. If Anna is given a 10 meter head start, how many seconds would it take for Elsa to catch up? Use an equation or system of equations to solve.
Step-by-step explanation:
Since Elsa is running at 2 and Anna at 1.75, we can first subtract
2 - 1.75 = 0.25, meaning each second Else gains 0.25m
Now that Anna was given a 10m headstart, we can divide 10 by 0.25
10/0.25 = 40
Meaning it would take 40 seconds for Elsa to catch up

Key: 2 | 1 | 0 means 12 for Bay Side and 10 for Seaside
Part A: Calculate the measures of center. Show all work. (2 points)
Part B: Calculate the measures of variability. Show all work. (1 point)
Part C: If you are interested in a smaller class size, which school is a better choice for you? Explain your reasoning. (1 point)
PLEASE HELP ASAP !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Part A: To calculate the measures of center, we can find the median and the mean for each school.
For Bay Side School, the median class size is the average of the 8th and 9th values when the data is sorted in ascending order. The 8th and 9th values are both 25, so the median class size is 25.
To find the mean class size for Bay Side School, we can add up all the class sizes and divide by the total number of classes. The sum of the class sizes is 12 + 12 + 12 + 14 + 15 + 15 + 16 + 16 + 18 + 18 + 20 + 20 + 23 + 25 + 25 = 243. There are 15 classes, so the mean class size is 243/15 ≈ 16.2.
For Seaside School, the median class size is the average of the 8th and 9th values when the data is sorted in ascending order. The 8th and 9th values are both 15, so the median class size is 15.
To find the mean class size for Seaside School, we can add up all the class sizes and divide by the total number of classes. The sum of the class sizes is 10 + 10 + 10 + 11 + 12 + 15 + 15 + 16 + 17 + 17Part A (continued):
18 + 18 + 20 + 20 + 25 = 222. There are 14 classes, so the mean class size is 222/14 ≈ 15.9.
Therefore, the measures of center for Bay Side School are: median = 25, mean ≈ 16.2.
The measures of center for Seaside School are: median = 15, mean ≈ 15.9.
Part B: To calculate the measures of variability, we can find the range and the interquartile range (IQR) for each school.
For Bay Side School, the range is the difference between the largest and smallest class sizes. The largest class size is 25, and the smallest class size is 12, so the range is 25 - 12 = 13.
To find the IQR for Bay Side School, we need to find the first quartile (Q1) and the third quartile (Q3) of the data. From the stem-and-leaf plot, we can see that Q1 is 15 and Q3 is 20. Therefore, the IQR is 20 - 15 = 5.
For Seaside School, the range is the difference between the largest and smallest class sizes. The largest class size is 25, and the smallest class size is 10, so the range is 25 - 10 = 15.
To find the IQRPart B (continued): for Seaside School, we need to find the first quartile (Q1) and the third quartile (Q3) of the data. From the stem-and-leaf plot, we can see that Q1 is 12 and Q3 is 18. Therefore, the IQR is 18 - 12 = 6.
Therefore, the measures of variability for Bay Side School are: range = 13, IQR = 5.
The measures of variability for Seaside School are: range = 15, IQR = 6.
Part C: If you are interested in a smaller class size, Seaside School is a better choice because its measures of center are lower than those of Bay Side School, indicating that its class sizes tend to be smaller on average. Additionally, Seaside School has a smaller range and IQR, indicating less variability in class size. Therefore, there is less chance of encountering very large classes at Seaside School compared to Bay Side School.
what value of x makes this equation true -(x+3)=2(x-3)
A. 0
B. 1
C. 2
D. 3
Answer:
To solve the equation -(x + 3) = 2(x - 3) for x, we can follow these steps:
Step 1: Distribute the negative sign on the left side of the equation:
-(x + 3) = 2(x - 3)
=> -x - 3 = 2(x - 3) (using the distributive property)
Step 2: Expand the right side of the equation:
-x - 3 = 2x - 6
Step 3: Add x to both sides of the equation to isolate the x term on one side:
-x + x - 3 = 2x + x - 6
=> -3 = 3x - 6
Step 4: Add 6 to both sides of the equation:
-3 + 6 = 3x - 6 + 6
=> 3 = 3x
Step 5: Divide both sides of the equation by 3 to solve for x:
3/3 = 3x/3
=> 1 = x
So, the correct value of x that makes the equation true is B. 1.
PLEASE MARK BRAILYISTT :D
Answer:
B, one
Step-by-step explanation:
In order to solve this, you can solve the equation. First, you can use the distributive property to get -x-3=2x-6. If you make the variables on one side and the constants on the other, you will get -3x-3=-6. This can further simplify to -3x=-6. Divide both sides by -3 to get that x=1. Then, the correct answer is B.

The function for the points are y = -15x - 5
How to determine the functionFrom the information given, we have that;
The points are;
(1/3,0) (-2 3/4,0) and (0,-5)
Using the point-slope form of a linear equation, we have;
y - y₁ = m(x - x₁)
Such that;
m is the slope of the liney - y₁ and (x - x₁) are the pointsUsing (1/3, 0) and (0, -5), we have that the slope is;
m = (0 - (-5))/0 -1/3)
expand the bracket
= 5 / (-1/3)
= -15
Now, take any of the given points and substitute the values
Using (1/3, 0), we get;
y - 0 = -15(x - 1/3).
y = -15x - 5.

The function for the points solved by (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)
We have given the points:
(1/3,0) (-2 3/4,0) and (0,-5)
Using the formula of linear equation
\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)
Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)
that is 1/3 = \(a\), 0 = \(a_{1}\) and
0 = \(b\), -5 = \(b_{1}\)
\(x\) refers to the slope of line (take any variable)
Now for finding the value of \(x\),
\(x=a-a_{1}/b-b_{1}\)
inserting the values,
\(x=[0-[-5]]/[0-1/3]\\x= -15\)
Substitute the value of \(x\) in the equation
\(a-0=-15[b-1/3]\)
By simplifying the equation, we get
\(a=-15b-5\)

Answer:
1,664 square yards
Step-by-step explanation:
Given: A triangular prism is 20 yards long and has a triangular face with a base of 24 yards and a height of 16 yards. The other two sides of the triangle are each 20 yards.
Surface area of the triangular prism:
The formula to determine the surface area of the triangular prism is
SA= bh+PL
where base: b=24
height: h=16
length: l=20
Perimeter: P= 20+20+24= 64
Next we follow the steps of the formula and our equation is:
SA= (24x16) + (64x20)
24x16= 384 and 64x20= 1280
384+1280= 1,664
SA= 1,664
the surface area of the triangular prism is 1664 square yards.

The pharmacist has a 2.8 L bottle of cough syrup. If she fills a bottle that is 1,200 ml, how many ml of cough syrup does the pharmacist have left?
160 ml
400 ml
1,600 ml
4,000 ml
Answer: 1,600 ml
Step-by-step explanation:
You can arrive at this answer by subtracting the amount of cough syrup used (1,200 ml) from the initial amount in the bottle (2.8 L, which is 2,800 ml).
2,800 ml - 1,200 ml = 1,600 ml
I hope this helps :)
Answer: 1,600 mL
Step-by-step explanation:
1. convert the 1,200 mL to L, which is 1.2 L.
2. Subtract that value from 2.8 L, equaling 1.6 L
3. Convert the 1.6 L back into mL by multiplying by 1000, which is equivalent to 1600 mL.
