Approximate percent increase from 1990 to 2010
Answers
The price of cable TV has increased by approximately 252.94% from 1990 to 2010.
The approximate percent increase from 1990 to 2010 can be calculated using the formula:
Percent increase = (Final value - Initial value) / Initial value * 100
To apply this formula, we first need to find the initial and final values. In this case, the initial value is the cost of cable TV in 1990, which is $17.00, and the final value is the cost in 2010, which is $60.00.
Now, let's calculate the percent increase:
Percent increase = ($60.00 - $17.00) / $17.00 * 100
= $43.00 / $17.00 * 100
≈ 252.94%
Therefore, the approximate percent increase from 1990 to 2010 is approximately 252.94%.

Step-by-step explanation:
When something is related proportionally, that means that multiply by some value constant k, will result in the output.
Thus, to find k, all you have to do is divide y/x

Helppp!!!!laura is playing a card game with her friend.she will draw two cards from those pictured.
A.list the sample space for all possible 2-card combinations Laura could make.
B.find the probability that both cards are even.
Answers
Answer:
10
30%
Step-by-step explanation:
In this case it would be the combination of 2 taken from 5.
That is, when n = 5 and r = 2
nCr = n! / r! * (n-r)!
replacing
5C2 = 5! / (2! * 3!)
5C2 = 10
Which means that the sample space is 10 possible combinations.
the probability that the card you draw is even is 3/5, since there are 3 even cards that exist and 5 is the total number of cards.
Now, so that both are for it would be the multiplication of the previous probability and 2/4 because an even card and a card in general have already been drawn:
(3/5) * (2/4) = 0.3
So the probability that both are even is 30%

1The volumes of two similar prisms are 972 cm3 and 36 cm3. The surface area of the larger prism is 594 cm2.
What is the scale factor for the similar figures? What is the surface area of the smaller prism?
Answers
Answer:
Part 1)
The scale factor of the smaller prism to the larger prism is 3
or
The scale factor of the larger prism to the smaller prism is 1/3
Part 2) The surface area of the smaller prism is 66 square centimeters
Step-by-step explanation:
Part 1) What is the scale factor for the similar figures?
we know that
If two figures are similar, then the ratio of their volumes is equal to the scale factor raised to the cube
Let
z ----> the scale factor
x ---> volume of the larger prism
y ---> volume of the smaller prism
so
[tex]z^3=\frac{x}{y}[/tex]
we have
[tex]x=972\ cm^3\\y=36\ cm^3[/tex]
substitute
[tex]z^3=\frac{972}{36}[/tex]
Simplify
[tex]z^3=27\\z=3[/tex]
therefore
The scale factor of the smaller prism to the larger prism is 3
or
The scale factor of the larger prism to the smaller prism is 1/3
Part 2) What is the surface area of the smaller prism?
we know that
If two figures are similar, then the ratio of their surface areas is equal to the scale factor squared
Let
z ----> the scale factor
x ---> surface area of the larger prism
y ---> surface area of the smaller prism
so
[tex]z^2=\frac{x}{y}[/tex]
we have
[tex]x=594\ cm^2[/tex]
[tex]z=3[/tex]
substitute
[tex]3^2=\frac{594}{y}[/tex]
solve for y
[tex]y=\frac{594}{9}=66\ cm^2[/tex]
therefore
The surface area of the smaller prism is 66 square centimeters

(- 2, - 3 )
Step-by-step explanation:
Given the 2 equations
2x - 4y = 8 → (1)
y = [tex]\frac{3}{2}[/tex] x → (2)
Substitute y = [tex]\frac{3}{2}[/tex] x into (1)
2x - 4([tex]\frac{3}{2}[/tex] x ) = 8
2x - 6x = 8
- 4x = 8 ( divide both sides by - 4 )
x = - 2
Substitute x = - 2 into (2) for corresponding value of y
y = [tex]\frac{3}{2}[/tex] × - 2 = - 3
Solution is (- 2, - 3 )

Use the distributive property to simplify the expression 15(14a)
Answers
Answer:
[tex]15(14a) = 210a[/tex]
Step-by-step explanation:
We want to simplify the expression 15(14a) using the distributive property.
We rewrite as:
[tex]15(14a) = 15(10a + 4a)[/tex]
According to the distributive property:
[tex]a(b + c) = ab + ac[/tex]
This implies that:
[tex]15(14a) = 15 \times 10a + 15 \times 4a[/tex]
We simplify to obtain:
[tex]15(14a) = 150a + 60a[/tex]
Add on the right to get:
[tex]15(14a) = 210a[/tex]

A Parabola, open curve, a conic section produced by the intersection of a right circular cone and a plane parallel to an element of the cone. A parabola is a plane curve generated by a point moving so that its distance from a fixed point is equal to its distance from a fixed line
The equation of the parabola is given by
( x - h )² = 4p ( y - k )
where ( h , k ) is the vertex and ( h , k + p ) is the focus
y is the directrix and y = k – p

Answers
Answer:
z = [20/sqrt(3][cos(-2π/3) + isin(-2π/3)]
Step-by-step explanation:
Polar form is

r = sqrt[(-10/sqrt3)² + (10)²]
r = sqrt(400/3)
r = 20/sqrt(3)
tan^-1[10 ÷ (10/sqrt(3))] = π/3

Find side A of a triangle with a B length of 7 and a C length of 25
A) 24
B) 19
C) 8
D) 30
Answers
Answer:
A 24
Step-by-step explanation:
Assuming this is a right triangle, we can use the Pythagorean theorem
a^2+ b^2 = c^2
a^2 + 7^2 = 25^2
a^2 +49= 625
Subtract 49 from each side
a^2 +49-49 = 625-29
a^2 = 576
Take the square root of each side
sqrt(a^2) = sqrt(576)
a = 24
Answer:
A
Step-by-step explanation:
C - B < A < C + B
25 - 7 < A < 25 + 7
18 < A < 32
A can have any length between 10 and 32.
In case it's a right angle triangle,
A² = 25² - 7²
A² = 576

A decorative steel is shown and it is made from circular circle and 6 stems.
The length of each stem is 45cm.
Workout the total length of steel used in the frame
Answers
The total length of the steel used in the frame is 270 cm, if the decorative steel up of 6 stems and each stem is 45 cm.
Step-by-step explanation:
The given is,
Decorative steel made from circular circle of 6 stems
The length of the stem is 45 cm
Step:1
We need to find the total length of the steel used in the decorative steel,
Let, T - Total length of the steel
L - Length of the stem
n - Number of stems used in steel frame
Step:2
Formula to find the total length of the steel is,
[tex]T=[/tex] [tex]l[/tex] × [tex]n[/tex]
From given,
[tex]l[/tex] = 45 cm
[tex]n[/tex] = 6 stems
Substitute the values in formula,
[tex]T =[/tex] ( 45 × 6 )
= 270
[tex]T =[/tex] 270 cm
Result:
The total length of the steel used in the frame is 270 cm.
The total length of steel used in the decorative steel frame, made with 6 stems of 45cm each, is 270cm.
Explanation:To solve this question, we simply need to multiply the length of each stem by the number of stems used in the decorative steel. As stated, each stem measures 45cm, and there are 6 stems used in total.
Therefore, the total length of steel used in the frame would be calculated as follows:
Determine the length of an individual stem: 45cmDetermine the total number of stems: 6Multiply these two figures together: 45cm * 6 = 270cmSo, the total length of steel used in the frame is 270cm.
