Step-by-step explanation:
If X represents the length of the side of a cube, the formula for the surface area of the cube, S =?
solution :
the area of each face of the cube = side × side
= X × X = X²
the cube has 6 similar faces, so the surface area of the cube could be:
S = 6 × X² = 6X²
Answer:
Surface Area = 6 × S²
Step-by-step explanation:
the surface area fo the cube :
SA = 6 × lenght × lenghtif lenght = S, the surface area fo the cube :
SA = 6 × lenght × lenght
SA = 6 × S × S
SA = 6 × S²

A marble is selected at random from a jar containing 30 red marbles, 10 yellow marbles, and 60 green marbles. Find the theoretical probability that it is either red or green.
there is a 90% chance its a red or green or a 90/100 chance
Step-by-step explanation:
first you need to count your whole which would be the sum of adding all the marbles which is 100 then add the red and green that's 90 lastly you make a fraction 90/100 (simple the fraction if asked )

is 628/1300 the same as 628 divided by 1300?
Answer:
Step-by-step explanation:
Yes
Answer:
yes
Step-by-step explanation:
here 628/1300 means
[tex] \frac{628}{1300} [/tex]
where
[tex] \frac{628}{1300} means 628 \div 1300[/tex]
where the sign ÷ shows divide
so we can say 628/1300=628 divided by 1300

Q1 (pic 1)
Triangle ABC is similar to triangle WYZ.
Select all angles whose cosine equals 35.
Question 1 options:
Angle W
Angle Y
Angle C
Angle B
Angle Z
Angle A
Q2 (pic 2)
Triangle ABC is similar to triangle WYZ.
Determine whether the following statement is true or false.
sin(B)>sin(Y)
Question 2 options:
True
False
Answer:
Question 2 = True
I don't know the first question, the test wouldn't tell me:/
Angle C, Angle Z, Angle A, and Angle W are all angles whose cosine equals 35 and the statement that Sin B is greater than Sin Y is false.
What is a similar triangle?The two triangles are said to be similar that have the same proportion of sides and angles.
Corresponding sides are in the same ratio.
a/p = b/q = c/r
In triangle ABC
AB = 5, AC = 3, BC = 4
Cos A = base/ hypotenuse
= 3/5
Cos B = base/ hypotenuse
= 4/5
Cos C = base/ hypotenuse
= 3/5
In triangle WYZ
Cos W = base/ hypotenuse
= 3/5
Cos Z = base/ hypotenuse
= 4/5
Hence, Angle C, Angle Z, Angle A, and Angle W are all angles whose cosine equals 35.
In triangle WYZ
WY = 13
In triangle ABC
CB = 24, AC = 10
Sin B = Perpendicular/ hypotenuse
= 10/26
Sin Y = Perpendicular/ hypotenuse
= 5/13
Since both angles are equal also they are similar to each other.
Therefore, the statement that Sin B is greater than Sin Y is false.

What is the arithmetic sum of sequence?Let a₁ be the first term, n the number of the terms, and l be the last term of the sequence.
Then the sum of all the terms will be given as,
S = [n (a₁ + l )] / 2
Let a₁ be the first term and d is the common difference between the terms. Then the nth term will be given as
[tex]\rm a_n = a_1 + (n - 1)d[/tex]
Beginning with Rodney’s first month of high school, his father deposits $5 into Rodney’s savings account.
Each month after the first month, his father deposits $2 more than the previous month.
Then the first term is $5 and the common difference is $2.
The total amount deposited in Rodney’s account after four years can be represented using the expression.
Then the total number of the terms will be
n = 4 x 12
n = 48 months
Then the 48th term of the sequence will be
a₄₈ = 5 + (48 – 1) · 2
a₄₈ = 5 + 47 · 2
a₄₈ = 5 + 94
a₄₈ = 99
Then the sum of the 48 terms will be
S = 48 (5 + 99) / 2
S = 24 × 104
S = $2,496
Then the correct option is A.

Complete the equation of this circle:
(x - [ ? ])2+(y - [ ])2= []
The complete equation of the circle graphed is (x - 2)² + (y + 2)² = 9
Determining the equation of the circle graphedFrom the question, we have the following parameters that can be used in our computation:
The circle
Where, we have
Center = (a, b) = (2, -2)
Radius, r = 3 units
The equation of the circle graphed is represented as
(x - a)² + (y - b)² = r²
So, we have
(x - 2)² + (y + 2)² = 3²
Evaluate
(x - 2)² + (y + 2)² = 9
Hence, the equation is (x - 2)² + (y + 2)² = 9
