The minute hand on the clock is 10 cm long and travels through an ark of 180° every 18 minutes. which measure is closest to the length of the art the minute hand travels through during this 18 minute period
Answer: The arc length of the clock is 31.42cm
Step-by-step explanation:
1. Use your section formula: S = r (Radius) θ (Theta: Angle in radians)
2. Convert your 180 degrees to radians by multiplying it by π / 180, resulting in π radians.
3. Take your radius of 10cms and multiply it by π, leaving 31.42cm. This is the length of the 180 degree arc.

Suppose the mean height in inches of all 9th grade students at one high school is estimated. The population standard deviation is inches. The heights of 10 randomly selected students are 75,62,69,65,66,64,67,70,74 and 63.
Answer:
The population mean = sample mean = x`= 67.5
Population standard deviation = 13.369
Sample standard deviation= 4.225
Step-by-step explanation:
AS the population mean is not given we will calculate it from the sample.
The mean of the sampling distribution is equal to the population mean .
The sample mean is calculated by
x`= ∑x/n= 75,+ 62, +69,+65,+66,+64, +67,+70,+74 + 63/10
x`=675/10= 67.5
The standard deviation of the sample is equal to
u = σ/ √n where σ is the population standard deviation and n is the number of observations.
Calculating the sample mean
s= √∑xi²/n- (∑x/n)²
s= √(45741/10)- (675/10)²
s= 4.2249
σ= u*√n= 4.229 *√10
σ=13.360

Given:
The figure of triangle LNM.
To find:
The Law of Sines for the given triangle.
Solution:
Law of sines: In triangle ABC,
[tex]\dfrac{\sin A^\circ}{a}=\dfrac{\sin B^\circ}{b}=\dfrac{\sin C^\circ}{c}[/tex]
Similarly, the Law of Sines for the given triangle LNM is:
[tex]\dfrac{\sin L^\circ}{l}=\dfrac{\sin N^\circ}{n}=\dfrac{\sin M^\circ}{m}[/tex]
Therefore, the correct option is b.

Given the function y = x/3 + 1, suppose you have a function value where x (input) is 6. What would be the corresponding y value (output)?
Answer:
3
Step-by-step explanation:
Given the function : y = x/3 + 1
If an input value, x is given as 6 ;
Output value, y can be obtained by Substituting the value x = 6 into the function and calculating the value of y
Calculation goes thus ;
y = 6/3 + 1
y = 2 + 1
y = 3
Output, y = 3
Dad is getting food ready for my birthday party! Including me, there will be 14 people at the party. Dad is baking cupcakes for us! He can bake 16 cupcakes per batch.
How many batches should I tell Dad to make so we can each have 5 cupcakes?
Answer:
5 batches
Step-by-step explanation:
fist to find how many cupcakes you need multiply the amount of people times amount of cupcakes per person
(if rule is 5 per person)
14x5=70
then you want to find how many batches to make
70/16=4.375
but you and make 0.375 batches so just make 1 more batch
so you should tell your dad to bake 5 batches

The probability that Sean does not miss the bus is 0.85.
What is the probability that Sean misses the bus?
A. 0.15
B. 0.25
C. 0.50
D. 0.85
E. 1.00
Answer:
0.25
because sum of probabilities is always equal to 1
i.e P(sean doesn't miss the bus)+P(sean misses the bus)=1
P(sean misses the bus) = 1-0.85 =0.25

11 5(2x + 1) + c(x + d) = 12x - 1
Work out the value of c and the value of d.
Answer:
c = 2, d = - 3
Step-by-step explanation:
Expand and simplify the left side then compare the coefficients of like terms on both sides.
5(2x + 1) + c(x + d) ← distribute parenthesis
10x + 5 + cx + cd
= x(10 + c) + 5 + cd
Compare like terms on both sides, that is
10 + c = 12 ( subtract 10 from both sides )
c = 2
Then
5 + cd = 5 + 2d and
5 + 2d = - 1 ( subtract 5 from both sides )
2d = - 6 ( divide both sides by 2 )
d = - 3

What is proportion?In general, the term "proportion" refers to a part, share, or amount that is compared to a total.
According to the concept of proportion, two ratios are in proportion when they are equal.
From the triangle it can be assume that ΔPSR is similar to ΔPQR.
Then, the ratio of corresponding sides of triangles are proportion.
So, PQ/ PS = QR/ RS

Step-by-step explanation:
Note how this drawing is symmetrical about a horizontal line drawn halfway between AB and CD and passing through the origin.
Line AB has been subdivided into two equal pieces of length 15, so the length of AB is twice 15, or 30. Due to the symmetry shown, line CD has the same length: 30.

Consider the following sequence
152, -76, 38, -19
Write a rule for the nth term and then find [tex]a_7[/tex]
Answer:
a₇ = 2.375
Step-by-step explanation:
There is a common ratio r between consecutive terms, that is
r = [tex]\frac{-76}{152}[/tex] = [tex]\frac{38}{-76}[/tex] = [tex]\frac{-19}{38}[/tex] = - [tex]\frac{1}{2}[/tex]
This indicates the sequence is geometric with nth term
[tex]a_{n}[/tex] = a₁ [tex](r)^{n-1}[/tex]
where a₁ is the first term and r the common ratio
Here a₁ = 152 and r = - [tex]\frac{1}{2}[/tex] , then
[tex]a_{n}[/tex] = 152 [tex](-\frac{1}{2}) ^{n-1}[/tex] , so
a₇ = 152 [tex](-\frac{1}{2}) ^{6}[/tex] = 152 × [tex]\frac{1}{64}[/tex] = 2.375
Answer:
Solution given:
first term [a]=152
second term[b]=-76
common ratio[r]=[tex] \frac{-76}{152}[/tex]=-1/2
now
for nth term ,we have
nth term =a [tex] {r}^{n -1} [/tex]
now
7th term==152[tex] {-1/2}^{7 - 1} [/tex]

Ashley flies a drone 2,530 ft in 5 s. At this rate how many miles does the drone fly in a minute? 1 mi = 5280 ft
Answer:
I think the answer is 5.75 miles.
Step-by-step explanation:
If the drone flies 2,530 ft in 5 seconds, that means that in one minute it flies 30,360 ft. And 30,360 divided by 5,280 is 5.75.
There are 5.74 miles does the drone fly in a minute.
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
Ashley flies a drone 2,530 ft in 5 s.
Now,
Since, Ashley flies a drone 2,530 ft in 5 s.
We know that;
1 minute = 60 seconds
Hence, Number of miles in 1 minutes = 2530/5 × 60
= 30,360 ft
Since, We know that;
1 ft = 0.000189 miles
Hence, we get;
⇒ 30360 × 0.000189
⇒ 5.74 miles
