Answer:
174.4 cm³
Step-by-step explanation:
The relevant volume formulas are ...
V = πr²h . . . . . cylinder of radius r and height h
V = 4/3πr³ . . . . sphere of radius r
__
Then the difference in volume between the cylinder and the 3 spheres is ...
ΔV = π(2.5 cm)²(14 cm) -3(4/3π(2 cm)³) = π(87.5 -32) cm³ = 55.5π cm³
The volume of air is about 174.4 cm³.
TRIGONOMETRY (RIGHT ANGLE) PLEASE HELP
Answers
Answer:
x = 41.05
Step-by-step explanation:
Given that,
In a right angles triangle,
Perpendicular height, P = 228
Angle 1 = 90°
Angle 2 = 47°
Angle 3 = 180-(90+47) = 43°
Using trigonometry to find x.
[tex]\sin\theta=\dfrac{P}{x}\\\\x=\dfrac{P}{\sin\theta}\\\\x=\dfrac{28}{\sin(43)}\\\\x=41.05[/tex]
So, the value of x is equal to 41.05.

Answers
Answer:
Mr. Akika has 11 18-cent stamps and 22 32-cent stamps.
Step-by-step explanation:
Given that Mr. Akika has 33 18 cent and 32 cent stamps all told, and the stamps are worth $ 9.02, to determine how many of each kind of stamp does he have the following calculation must be performed:
10 x 0.18 + 23 x 0.32 = 9.16
11 x 0.18 + 22 x 0.32 = 9.02
Therefore, Mr. Akika has 11 18-cent stamps and 22 32-cent stamps.

Answers
Answer:
18 15/16 ft
Step-by-step explanation:
what is the request here ?
to do the additions and bring all to one summary result of ft ?
I base my answer on this assumption.
10 1/16 = 161/16
8 3/8 = 67/8
1/2 = 1/2
note let's bring everything to 16th, so that we can actually add them.
161/16
67/8 = 134/16
1/2 = 8/16
161/16 + 134/16 + 8/16 = 303/16 = 18 15/16
cross check :
add all whole numbers first, and then add the remaining fractions too (need to bring them to 16th too).
10 + 8 = 18
1/16 + 3/8 + 1/2 = 1/16 + 6/16 + 8/16 = 15/16
together, 18 15/16
yeah, it is the same.

The first three terms of a sequence are given. Round to the nearest thousandth (if necessary).
50,20,8
Find the 8th term.
Answers
Answer:
.082
Step-by-step explanation:
First find the common ratio
Take the second term and divide by the first term
20/50 = 2/5 = .4
Check with the third term divided by the second term
8/20 = .4
The formula for a geometric sequence is
an = a1 (r) ^(n-1) where a1 is the first term and r is the common ratio
=50 ( .4) ^ (n-1)
We want to find the 8th term
= 50 ( .4)^(8-1)
= 50 ( .4) ^7
=0.08192
Round to the nearest thousandth
= .082

What is the slope and y-intercept of 6x-5y=13
Answers
Answer:
The slope is 6/5 and the y intercept is -13/5
Step-by-step explanation:
6x-5y=13
Solve for y
Subtract 6x from each side
6x-6x-5y=-6x+13
-5y = -6x+13
Divide by -5
-5y/-5 = -6x/-5 +13/-5
y = +6/5x -13/5
This is in slope intercept form y = mx+b where m is the slope and b is the y intercept
The slope is 6/5 and the y intercept is -13/5
What is the slope of the line represented by the equation y = -1/2X + 1/4?

a. What is the probability that a customer buys three tires?
b. Construct a cumulative probability distribution for the number of tires bought.
Answers
Answer:
A. Probability = 0.02
B. This is in a cumulative frequency table in the attachment I added
Step-by-step explanation:
A. We have these following probabilities
Prob(X=0) = 0.05
Prob(x= 2) = 0.30
Prob(X = 4) = 0.50
Prob(X < 2) = Prob(X=0) + prob(X=1)
0.18 = 0.05 + prob(X=1)
prob(X=1) = 0.13
A. Prob(x = 3)
= 1 - (0.05 + 0.13 + 0.30 + 0.50)
= 0.02
Probability of buying only 3 times = 2%
B. The cumulative frequency is in the attachment.

In the triangle below, what is the cosine of 45°? Someone please help ASAP
Answers
Answer:
B. 1/√2
Step-by-step explanation:
Soh Cah Toa
cos is adjacent over hypotenuse so from either 45° degree angle it is 1/√2
For the given right angle triangle, cos 45 = 1/√2
Hence, option B is correct.
In the given triangle,
Adjacent = 1
Hypotenuse = √2
Since we know,
The values of all trigonometric functions depending on the ratio of sides of a right-angled triangle are defined as trigonometric ratios. The trigonometric ratios of any acute angle are the ratios of the sides of a right-angled triangle with respect to that acute angle.
For a right angled triangle,
Cosθ = adjacent / hypotenuse
Therefore,
cos 45 = 1/√2

A survey conducted by General Motors of 38 drivers in America, 34 indicated that they would prefer a car with a sunroof over one without. When estimating the proportion of all Americans who would prefer a car with a sunroof over one without with 99% confidence, what is the margin of error
Answers
Answer:
The margin of error is of 0.1282 = 12.82%.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the z-score that has a p-value of [tex]1 - \frac{\alpha}{2}[/tex].
The margin of error is of:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
A survey conducted by General Motors of 38 drivers in America, 34 indicated that they would prefer a car with a sunroof over one without.
This means that [tex]n = 38, \pi = \frac{34}{38} = 0.8947[/tex]
99% confidence level
So [tex]\alpha = 0.01[/tex], z is the value of Z that has a p-value of [tex]1 - \frac{0.01}{2} = 0.995[/tex], so [tex]Z = 2.575[/tex].
What is the margin of error?
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
[tex]M = 2.575\sqrt{\frac{0.8947*0.1053}{38}} = 0.1282[/tex]
The margin of error is of 0.1282 = 12.82%.
