Answer:
288 [tex]\pi[/tex] cm³
Step-by-step explanation:
diameter = 12 cm
radius = diameter/ 2
= 12/ 2
= 6 cm
volume of a sphere = 4/ 3 × [tex]\pi[/tex] × (6)³
= 4/ 3 × [tex]\pi[/tex] × 216
= ( 864 [tex]\pi[/tex])/ 3
= 288 [tex]\pi[/tex] cm³
A line passes through the point (2, 10) and has a y-intercept of 4. What is the equation of the line?
Answer:
[tex]y=3x+4[/tex]
Step-by-step explanation:
Hi there!
What we need to know:
Linear equations are typically organized in slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when x is equal to 0)1) Determine the slope (m)
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex] where two points that the line passes through are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]
We're given the point (2,10) and the y-intercept of 4. Recall that the y-intercept occurs when x is equal to 0. This means that the y-intercept occurs at (0,4), giving us our second point.
Plug these points into the equation
[tex]=\frac{10-4}{2-0}\\=\frac{6}{2}\\=3[/tex]
Therefore, the slope of the line is 3. Plug this into [tex]y=mx+b[/tex]
[tex]y=3x+b[/tex]
2) Determine the y-intercept (b)
The y-intercept is given; it is 4. Plug this back into [tex]y=3x+b[/tex]
[tex]y=3x+4[/tex]
I hope this helps!

Answer:
85 cm
Step-by-step explanation:
Answer:
68 cm
Step-by-step explanation:
Use the following formula (Pythagorean Theorem) to solve for c:
[tex]c^{2}= \sqrt{(a^{2}) - (b^{2})[/tex]
Substitute values:
[tex]c^{2}= \sqrt{(77^{2}) - (36^{2})[/tex]
Simplify:
[tex]c^{2}= \sqrt{(5,929) - (1,296)}[/tex]
[tex]c^{2}= \sqrt{4633}[/tex]
c ≈ 68 (rounded from 68.07)

The wild things pet store has 4 birdcages with 6 canaries in eacg cage. The pet store also has a birdcage with i oarakeets. Which expression shows the number of birds in wild things pet store?
Answer:
(4 * 6) + 8
Step-by-step explanation:
The Wild Things Pet Store has 4 birdcages with 6 canaries in each cage. The pet store also has a birdcage with 8 parakeets. Which expression shows the number of birds in Wild Things Pet Store?
Solution:
Each birdcage contain 6 canaries, therefore since there is a total of 4 birdcages, the number of canaries in the 4 bird cages is given by:
Number of canaries = 4 birdcages * 6 canaries per birdcage
Also, there is one birdcage with 8 parakeets, hence the number of parakeets is:
Number of Parakeet = 1 birdcage * 8 parakeet per birdcage = 8 parakeet
The total number of birds in the Pet store = number of canaries + number of parakeet
number of birds in the Pet store = (4 * 6) + 8

The height of a cuboid whose volume is 275 cm3 and base area is 25 cm2 is:
Given:
The volume of a cuboid = 275 cm³
The base area of the cuboid = 25 cm²
To find:
The height of the cuboid.
Solution:
We know that, the volume of a cuboid is:
[tex]V=l\times b\times h[/tex]
Where, l is length, b is breadth and h is the height.
It is also written as:
[tex]V=B\times h[/tex] ...(i)
Where, B is the base area and h is the height of the cuboid.
Putting [tex]V=275, B=25[/tex] in (i), we get
[tex]275=25\times h[/tex]
[tex]275=25h[/tex]
[tex]\dfrac{275}{25}=h[/tex]
[tex]11=h[/tex]
Therefore, the height of the cuboid is 11.

What is 5/9 +1/3 = I appreciate all answers!!
1.) Multiply Denominator:
9x3= 27
27 will be your new denominator for your answer.
then take 5 and multiply by 3.
5x3=15
then take 1 and multiply by 9.
1x9=9
Afterwards, you plus 15 and 9 to get 24.
so your fraction for the end will be 24/27.
PLZ HELP ASAPPP I just need with 1 and 2 this is my very last assignment! Thank you guys for all your help this yr!
Answer:
1. a = 32.96 m∠B = 21° b = 12.74
2. x = 24.99
Step-by-step explanation:
1. Use the law of sines:
a/sin 112 = 26/sin 47
a = 26 sin 112/sin 47
a = 32.96
m∠B = 180 - 47 - 112 = 21°
b/sin 21 = 26/sin 47
b = 26 sin 21/sin 47
b = 12.74
2. Use the law of cosines
[tex]x^{2} = 17^{2} + 11^{2} - 2(17)(11) cos 125[/tex]
= 289 + 121 - 374 cos 125
= 624.5175....
x = [tex]\sqrt{624.5175...}[/tex]
= 24.99

During the month of June, Addison kept track of the number of days she saw birds in her garden. She saw birds on 18 days of the month. What is the experimental probability that she will see birds in her garden on July 1? (There are 30 days in June) HURRYYYYY PLEASE
Answer:
3/5
Step-by-step explanation:
Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.
For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one is attached to the event. If it doesn't a value of zero is attached to the event.
Experimental probability is based on the result of an experiment that has been carried out multiples times
experimental probability that she will see birds in her garden on July 1 = number of days she saw a bird in June / total number of days in June

If 9x x 3x+1 = 2187, what is the value of x?
Answer:
x = 80.96
Step-by-step explanation:
9x * 3x +1 = 2187
27x +1 = 2187
27x = 2187-1
27x = 2186
x = 2186/27 = 80.96(2dp)

On a quiz there are four multiple-choice questions worth 3 points each and two true/false questionsworth 1 point each . Each multiple-choice question has five possible choices . If a student randomlyguesses on each question , what is the expected value of the student's score on the test ?
Answer:
The expected value of the student's score on the test is 3.4.
Step-by-step explanation:
Multiple choice questions:
worth 3 points.
Five possible choices, one of which is correct. So the expected value of the student in each multiple choice question is:
[tex]m = 3\frac{1}{5} = 0.6[/tex]
True/false questions:
worth 1 point.
2 options, one of which is correct, so the expected value for each is:
[tex]t = 1\frac{1}{2} = 0.5[/tex]
What is the expected value of the student's score on the test ?
4 multiple choice, two true-false. So
[tex]E = 4m + 2f = 4(0.6) + 2(0.5) = 2.4 + 1 = 3.4[/tex]
The expected value of the student's score on the test is 3.4.
