What is Algebra?
Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
We are given that;
Graph y = sin(x)
Boat travel= 7m
Now,
Let y be the height of the barnacle and x be the distance the boat has traveled
i.e, x = 7 meters
to find the height y :
Substitute the value of x =7 meters in [1] we have;
y = sin(7)
≈0.657.
Therefore, by algebra the answer will be 0.657 meters.

Cam is making a party hat, shown at left, in the shape of a cone for his
birthday. The circumference of the part of his head where the hat will
rest is 56 centimeters (cm). If the height of the hat is 25 cm, which of
the following is closest to the volume of Cam's hat, measured in cubic
centimeters (cm)?
Answer:
V≈2,080cm^3 Hope I helped :)
Step-by-step explanation:
The volume of a cone of radius r and height h is:
V=1/3πr^2h
Since the circumference of Cam's head is 56
2πr=56
r=56/2π
r=28/π
The volume of the hat is therefore:
V=1/3π(28/π )^2(25)
V=1/3((28)^2/π)(25)
V=1/3(19,600/π)
V≈2,080cm^3
The volume of the Cam's hat measured in cubic centimetres is 2081 cm³
Volume of a cone:The volume of a cone is as follows:
v = 1 / 3 π r²hwhere
h = height
r = radius
The circumference of the part of his head where the hat will rest is 56 cm. Let's find the radius
circumference = 2πr56 = 2 × π × rr = 28 / πh = 25 cm
V = 1 / 3 × π × (28 / π )² × 25
V = 1 / 3 × π × 784 / π² × 25
V = 19600 / 3π
V = 19600 / 9.42
V = 2080.67940552
V ≈ 2081 cm³

HELP FAST! A cat spies a bird sitting at the top of a 32 foot pole. If the angle of elevation from the cat to the bird is 47°, then the cat is __________ feet from the base of the flagpole. Select one:
a. 29.880
b. 29.890
c. 29.820
d. 29.800
e. 29.840
Answer:
e. 29.840
Step-by-step explanation:
The cat, the floor and the foot pole form the shape of a right angled triangle.
The opposite is the height of the foot pole = 32 ft
The adjacent is the distance of the cat from the base of the foot pole.
The hypotenuse is the direct distance of the cat from the bird.
The angle of elevation, x, is 47°
To find the distance of the cat from the foot of the foot pole, we can use to TAN part of the trigonometric function SOHCAHTOA:
tan(x) = opposite / adjacent
=> tan(47) = 32 / adj
adj = 32 / tan(47)
adj = 29.840 ft
Therefore, the cat is 29.840 feet from the base of the foot pole.
Wilson needs 9 pieces of wood that are each 1/3 ft long. He has one board that is 3 1/3 ft long. Will he be able to make all the pieces he needs from that one board?
Answer:
Yes, he will.
Step-by-step explanation:
Since he needs 9 pieces of 1/3 ft, yo would start by dividing 9 by 3 (9 x 1/3). This would give you 3, meaning that you would need 3 feet of would in all, and since he is given 3 and 1/3 feet, he has enough.

Step-by-step explanation:
Malik's goal is a minimum total of 135 (45 x 3) minutes per week, in three session of 45 minutes.
Notice that it is at least.
So He can do sessions from 3 , 4, 5, 6 up to 7 nights per week

what is the LCM of x^2+5 and x^2+10x+25?
Answer:
(x+5)²(x²+5)
Step-by-step explanation:
Given two functions x²+5 and x²+10x+25, to get their Lowest common factor, we need to to first factorize x²+10x+25
On factorising we have:
x²+5x+5x+25
= x(x+5) +5(x+5
= (x+5)(x+5)
= (x+5)²
The LCM can be calculated as thus
| x²+5, (x+5)²
x+5| x²+5, (x+5)
x+5| x²+5, 1
x²+5| 1, 1
The factors of both equation are x+5 × x+5 × x²+5
The LCM will be the product of the three functions i.e
(x+5)²(x²+5)

Answer: True
Step-by-step explanation: The angles given are the same AND the side given us the same. The triangle has been reflected, but the reflection is still congruent.
The two triangles given are congruent according to the ASA congruence rule.
What is ASA congruence rule ?Two triangles are congruent if two angles and the included side of one triangle are equal to two angles and the included side of the other triangle.
Check whether the triangles are congruent :The given triangles are both right angled triangles.
The side 12 units is the included side between the angles 45° and 90° in both the triangles. This is the required condition for ASA congruence rule.
Hence we can say that the triangles are congruent according to the ASA congruence rule. The answer is A.True.

Tom can do a job in 4 hours while Sam can do it in 6 hours. How many hours would it take to complete this job if they work together?
Answer:
12/5hours=2.4 hours
Step-by-step explanation:
Sam:6hours
Tom:4hours
This is a rate problem
Sam's rate is one job completed in 6 hours which is 1/6
Tom's rate is one job completed in 4 hours which is 1/4
Together, they could complete 1/4+1/6 of the job in y hours
We are trying to find the rate at which Sam and Tom could complete the job together, or one job in x days, for a rate of 1/y
1/4+1/6=1/y
The least common denominator is 12y
Multiplying through by the LCD which gives:
12y(1/4)+ 12y (1/6)= 12y (1/y)
3y + 2y=12
5y = 12
y=12/5 hours=2.4hours
Therefore it will take 12/5 hours or 2.4 hours to complete the job if they work together

What is the probability of selecting a boy or a blonde-haired person from 12 girls, 5 of whom have blonde-haired and 15 boys, 6 of whom have blonde-haired
Answer: 20/27
Step-by-step explanation:
So it is non- mutually exclusive;
Let B for the boys and H for the blond hair.
P(B) = 15/27; P(H) 11/27; P(B and H) = 6/27
Then, we have,
P(B or H) = 15/27 + 11/27 - 6/27
P(B or H) = 20/27
Therefore, the probability of selecting a boy or a blond-haired person is 20/27.
