Answer:
10 classes
Step-by-step explanation:
Given equations in the question
Dance World: y = 15x
Toe Tappers: y = 25 + 12.5x
Where,
x = number of classes
Equate the total cost at both dance studios
15x = 25 + 12.5x
Collect like terms
15x - 12.5x = 25
2.5x = 25
Divide both sides by 2.5
2.5x / 2.5 = 25 / 2.5
x = 10 classes
x = number of classes = 10

I need to know the surface area of this prism please help !!!! I will give brainlist !
Answer:
614
Step-by-step explanation:
15 x 13 = 195 two times 195 x 2 = 390
4 x 15 = 60 two times 60 x 2 = 120
4 x 13 = 52 two times 52 x 2 = 104
104 + 120 + 390 = 614
Answer:
SA = 2(l·w)+2(w·h)+2(l·h)
SA = 614 sq in
Step-by-step explanation:
SA = 2(4x13)+2(13x15)+2(4x15)
= 2(52)+2(195)+2(60)
= 104 + 390 + 120
= 614

Answer:
-9
Step-by-step explanation:
Using the sum/difference property of logarithms, we can rewrite the expression given as:
log b^3 + log c^3 - log √(a^3) --> log √(a^3) can also be written as log a^1.5
Next, we can use the power property of logarithms, and rewrite it again as:
3log b + 3log c - 1.5log a
Now, we can substitute the values of log a, log b, and log c:
3(11) + 3(-9) - 1.5(10)
33 - 27 - 15
-9
Simplifying, we get -9 as the answer.
The dial on an old telephone is a plastic ring 8cm in diameter with a4cm diameter hole in the center. Ten small dialing holes each of diameter 1.2cm are cut out of the ring
Answer:
Area of remaining plastic = 36.55 cm² (Approx.)
Step-by-step explanation:
Given:
Diameter of plastic dial of telephone = 8 cm
Diameter of middle hole = 4 cm
Diameter of ten small holes = 1.2 cm
Find:
Area of remaining plastic
Computation;
Radius of plastic dial of telephone = 8/2 = 4 cm
Radius of middle hole = 4/2 = 2 cm
Radius of ten small holes = 1.2/2 = 0.6 cm
Area of remaining plastic = Area of plastic dial - Area of middle hole - 10[Area of small holes]
Area of remaining plastic = π(4)² - π(2)² - π(0.6)²
Area of remaining plastic = π(16) - π(4) - π(0.36)
Area of remaining plastic = π[16 - 4 - 0.36]
Area of remaining plastic = π[11.64]
Area of remaining plastic = (3.14)(11.64)
Area of remaining plastic = 36.5496
Area of remaining plastic = 36.55 cm² (Approx.)
What is the value of x?
Answer:
look at the picture I have sent
Answer:
D
Step-by-step explanation:
Using the sine ratio or the cosine ratio in the right triangle.
Choosing the sine ratio with the exact value
sin45° = [tex]\frac{\sqrt{2} }{2}[/tex] , then
sin45° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{x}{10}[/tex] = [tex]\frac{\sqrt{2} }{2}[/tex] ( cross- multiply )
2x = 10[tex]\sqrt{2}[/tex] ( divide both sides by 2 )
x = 5[tex]\sqrt{2}[/tex] → D
What is considered the most famous impossible problem from Greek
antiquity?
A. Bisecting any angle
B. The Koch curve
C. The Delian problem
D. Playfair's axiom
Answer: C: the Delian problem
Step-by-step explanation: the Delian problem includes doubling a cube which was a famous impossible problem
The most famous impossible problem from Greek antiquity is The Delian problem.
What is Greek antiquity?
The Greek difficulties of antiquity were a collection of geometric issues, and the only tools available to solve them were a compass and a straightedge. The only problems are:
Duplication of cubes.angle trisectionsquaring of circlesSolution:
The Delian problem, doubling the cube, is considered one of the most famous impossible problems from Greek antiquity. Two others are the trisection of the general angle and squaring of a circle(also a famous problem)
Whereas the other options like the Koch curve, bisecting any angle and playfair's axiom is known for its possibilities.
Hence the Delian problem is the most famous impossible problem from Greek antiquity.

Stock in Hamburgertronics entered the day at a value of $22.50. By the end of the day, the value of the stock had increased by 2%. What was the value of Hamburgertronics stock at the end of the day?
Answer:
$22.95
Step-by-step explanation:
Given data
Value=$22.50.
Percent increase= 2%
Let us find the value of 2% increase
=2/100*22.50
=0.02*22.50
=$0.45
Hence the total value at the end of the day is
=22.50+0.45
=$22.95
7th grades math help me pleaseeee
Answer:
7 attendees
Step-by-step explanation:
From the above question, we know that:
$10 = 5 attendees
$14 = x
Cross Multiply
$10 × x attendees = $14 × 5 attendees
x attendees = $14 × 5 attendees/$10
x attendees = 7 attendees
Therefore, if the budget for the cooperate team building is $14, the number of attendees is 7

x=15-y
y=13-z
z=12-x
Answer:
x = 7; y = 8; z = 5
Step-by-step explanation:
x = 15 - y
y = 13 - z
z = 12 - x
The first equation is solved for x. Substitute x in the third equation with 15 - y from the first equation.
z = 12 - (15 - y)
z = 12 - 15 + y
z = y - 3 (Equation 1)
Now substitute y - 3 for z in the original second equation.
y = 13 - z
y = 13 - (y - 3)
y = 13 - y + 3
2y = 16
y = 8
Substitute 8 for y in Equation 1.
z = y - 3
z = 8 - 3
z = 5
Substitute 5 for z in the original third equation.
5 = 12 - x
-7 = -x
x = 7
Solution: x = 7; y = 8; z = 5

Find the roots of f(x)=x^2+10x−96
I really just need the step by step-
cant find out how to get the answer
Answer:
x = -16 or x = 6
Step-by-step explanation:
To find the roots of a polynomial function, set the polynomial equal to zero and solve for x.
x² + 10x - 96 = 0
We need to factor the left side. The left side is a quadratic polynomial whose first coefficient is 1. We need two numbers whose product is -96 and whose sum is 10. The numbers are 16 and -6.
(x + 16)(x - 6) = 0
If a product of two factors equals zero, then one factor or the other or both must equal zero.
x + 16 = 0 or x - 6 = 0
x = -16 or x = 6
