The number in question is 7.5
Step-by-step explanation:
15 ÷ 2 = 7.5
Why divide by 2? Because dividing by 2 is the inverse of multiplying by 2. To double-check our solution, just multiply 7.5 by 2... and 15!!
A point on a wheel moves at 32π/9 radians per minute. How many seconds are required for the point to complete 7 revolutions?
Answer:
The number of seconds required to complete 7 revolutions is 236.28 s.
Step-by-step explanation:
Given;
speed of the point on the wheel, ω = 32π/9 rad/min
number of revolutions made by the point, θ = 7 rev
The time taken for the point to make 7 revolutions is calculated as follows;
1 rev = 2π rad
[tex]time (t) = \frac{\theta }{\omega} = \theta \ \times \frac{1}{\omega} \\\\t = (7 \ rev \ \times \frac{2 \pi \ rad}{1 \ rev} ) \ \times (\frac{1}{32 \pi/9 \ \frac{rad}{\min} } )\\\\t = (7 \times 2\pi \ \ rad) \times (\frac{9}{32 \pi }\frac{\min}{rad}) \\\\t = 14 \pi \ (rad) \ \times \ \frac{9}{32 \pi}\ (\frac{\min}{rad} )\\\\t = \frac{14 \times 9}{32} \ \min\\\\t = 3.938 \ \min\\\\t = 3.938 \ (\min) \times \frac{60 \ s}{1 \ \min} \\\\t = 236.28 \ s[/tex]
Therefor, the number of seconds required to complete 7 revolutions is 236.28 s.
If you need to round up to the nearest tenth for this question, you'd put 236.3

Factor out the GCF 4x2y + 20x3y4 - 16xy
Question is below ( explanation)
To find the rate, you must divide the distance traveled by the time it took.
17.5 m is the distance while time it took was 5 seconds.
So,
17.5 ÷ 5 = 3.5 m/s
The rate of the anchor is 3.5 m/s
Note: I did not ignore the negative sign in the distance but rather acknowledged it as a magnitude. This meant that the anchor was dropping down instead of going up.

5. A trapezoid has a base of 20 inches and 30 Inches. The height of the trapezoid is 15
inches. What is the area of the Trapezoid in square inches?
Add the top and bottom together, divide by 2 then multiply by the height.
20 + 30 = 50
50/2 = 25
25 x 15 = 375
The area is 375 square inches.

Rosa has a picture frame that measures 12 inches by 18 inches. Which measurement is closest to the diagonal distance across the frame?
A. 6 inches
B. 21.6 inches
C. 30 inches
D. 36 inches
Answer:
B:21.6
Step-by-step explanation:
12²+18²=C
144+324=468
V468=21.6
Answer:
B 21.6
Step-by-step explanation:
You can solve this using the Pythagorean theorem:
h² = l² + w²
h² = 18² + 12²
h² = 324 + 144
h² = 468
h = √468
h ≈ 21.6
1. The standard deviation of sample size of n = 15 is 345 and the mean is 6784. Given that the
population follows a normal distribution, construct a 90% confidence interval estimate of the
mean of the population.
Answer:
The 90% confidence interval estimate of the mean of the population is between 6627 and 6941.
Step-by-step explanation:
We have the standard deviation for the sample, which means that the t-distribution is used to solve this question.
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 15 - 1 = 14
90% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 14 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.9}{2} = 0.95[/tex]. So we have T = 1.761
The margin of error is:
[tex]M = T\frac{s}{\sqrt{n}} = 1.761\frac{345}{\sqrt{15}} = 157[/tex]
In which s is the standard deviation of the sample and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 6784 - 157 = 6627
The upper end of the interval is the sample mean added to M. So it is 6784 + 157 = 6941
The 90% confidence interval estimate of the mean of the population is between 6627 and 6941.

25 is 32% of what number
Answer:
78.125
Step-by-step explanation:
0.32*x = 25
x = 25/0.32 = 78.125
Answer:
78.125
Step-by-step explanation:
Let the number be Y
32% of Y = 25
32/100 x Y = 25
32Y = 25x100
32Y = 2500
divide both sides by 32
Y = 2500/32
Y = 78.125
simplify using distributive law ;
1.) X n ( X n Y )
2.) ( X n Y ) u ( X n Y )
Answer:
X n Y , X n Y
Step-by-step explanation:
1) Use Associative law:
X n (X n Y) = (X n X) n Y
Idempotent law:
= X n Y
2) it is in the 'distributed' form, thus we need to reverse the distribution,
akin to 'factorization':
(X n Y) u (X n Y) = (X n (Y u Y))
which can be further simplified using idempotent law:
= X n Y
