✨find the surface area of the right cone shown. (Around the result to two decimal place)✨
Answers
Answer:
A = 388.58 cm^2
Step-by-step explanation:
For a cone whose base has a radius R, and a hypotenuse S, the area is:
A = pi*R^2 + pi*R*S
Where pi = 3.14
In this case, we can see that the diameter is: 15cm
Then the radius, half of the diameter, is:
R = 15cm/2 = 7.5cm
The hypotenuse is 9cm, then S = 9cm
A = 3.14*(7.5cm)^2 + 3.14*(9cm)*(7.5cm) = 388.575 cm^2
Rounding to two decimal places, we need to look at the third one, which is a five, so we need to round up:
A = 388.58 cm^2

A line passes through the point (2, 10) and has a y-intercept of 4. What is the equation of the line?
Answers
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:
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
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?
Answers
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

Answers
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
= 18/30

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 ?
Answers
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.

The height of a cuboid whose volume is 275 cm3 and base area is 25 cm2 is:
Answers
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.
