Answer:
24%
Step-by-step explanation:
Probability for a female to win the iPad= 30/50
And a male to win the TV= 20/50
[tex]\frac{30}{50}[/tex]×[tex]\frac{20}{50}[/tex]
[tex]=\frac{600}{2500}[/tex]
[tex]=\frac{6}{25}[/tex]

Juana is measuring two pyramids whose base are isosceles right triangles. The second pyramid has the same height, but has 9 times the volume. What is the side length of its base
9514 1404 393
Answer:
3 times the smaller triangle base
Step-by-step explanation:
The volume is proportional to the height and to the area of the base.
If the height is unchanged, the larger pyramid must have a triangular base with an area that is 9 times the smaller base area.
Since the bases are similar, the area ratio is the square of the side length ratio. The side lengths of the larger base triangle must be √9 = 3 times the side lengths of the smaller base triangle.

Consider these three squares with known area. 3 squares. The smallest square is labeled 25, the next square is 144, and the largest square is 169. Can a right triangle be formed using these squares?
Answer:
The answer is "5, 12, and 13".
Step-by-step explanation:
Please find the complete question in the attached file.
The right triangle is a triangle with only an angle of 90 degrees, as well as the go in the angle of 90 degrees, which is considered a hypotenuse.
The hypotenuse calculation square is equivalent to both the squared measures of the other two sides:
[tex]C^2=A^2+B^2[/tex]
And even those squares do verify the equation:
[tex]169 = 144 + 25[/tex]

A fashion blog has 22,000 page views so far. In addition, that number grows 25% every week. Which function can be used to determine the number of page views the blog will have after x weeks?
Answer: 22,000 * 1.25^ x
Step-by-step explanation:
The number of pages grows at 25% every week. This number is based on the previous week's number of pages so the increase in page number is being compounded.
Use the future value equation to determine the number of pages after x weeks.
FV = Amount * ( 1 + rate of increase) ^ time
= 22,000 * ( 1 + 25%) ^ x
= 22,000 * 1.25^x
Jacqueline is deciding between two mortgages for her new home. The first
mortgage is an 80/20 mortgage with interest rates of 4.75 and 7.525%,
respectively. The second mortgage is a 30-year mortgage with a 5.25% and a
$58.30 monthly PMI. If the house price is $145,000, which mortgage payment
will be lower initially, and by how much?
A. 30-year mortgage by $49.93
B. 80/20 mortgage by $41.34
C. 80/20 mortgage by $50.62
D. 30-year mortgage by $33.56
Answer:
80/20 mortgage by $37.25
Step-by-step explanation:
First mortgage
0.8 × 145000 = 116000 PMT multiply both of them
= 116000(.0475/12) / [1 - (1 + .0475/12)^(-12 * 30)] PMT = 605.11
The 2nd Mortgage 0.2 × 145000 = 29000
2nd mortgages are normally only interest payments
I = 29000(.07525/12) I = $181.85 divide the interests by the denominator
605.11 + 181.85 = 786.96
Second Mortgage
PMT = 145000(.0525/12) / [1 - (1 + .0525/12)^(-12 * 30)] divide the mortage
PMT = 800.70
800.7 + 58.3 = 859.00
Therefore, the 80/20 mortgage is lower by $37.25¢

If you roll one die, what is the probability of getting an odd number or a 4? Are the events inclusive or mutually exclusive?
Answer:
4/6
Step-by-step explanation:
The probability of getting an odd number or a 4 is,
⇒ P = 1/2
We have to given that,
Roll one die for the probability of getting an odd number or a 4.
Now, We know that,
Total outcomes are,
⇒ 1, 2, 3, 4, 5, 6
Hence, Odd numbers are,
⇒ 3, 5
So, The probability of getting an odd number is,
⇒ 2 / 6
⇒ 1 / 3
And, The probability of getting 4 is,
⇒ 1 / 6
Thus, the probability of getting an odd number or a 4 is,
⇒ P = 2/6 + 1/6
⇒ P = 3/6
⇒ P = 1/2

Step-by-step explanation: Hope this help :D
Answer:
A. 4x * 2x^2 + 4x * (-2) + 1 * 2x^2 + 1 * (-2)
Step-by-step explanation:
We have the binomial (4x + 1)(2x^2 - 2) and are asked to see how it looks like expanded.
When solving binomials, we need to follow the FOIL method :
First - First number in first parenthesis multiplied by first number in second parenthesis
Outer - First number in first parenthesis multiplied by second number in second parenthesis
Inner - Second number in first parenthesis multiplied by first number in second parenthesis
Last - Second number in first parenthesis multiplied by second number in second parenthesis
If we follow the definitions given, we can find our correct answer and also see where all the other answers mess up at :
A. 4x*2x^2+4x*(-2)+1*2x^2+1*(-2)
This follows FOIL entirely from start to finish.
B. 4x*2x^2+4x*(-2)+1*4x+1*(-2)
This did not follow the Inner part of FOIL.
C. 4x*2x^2+4x*(1)+1*2x^2+1*(-2)
This did not follow the Outer part of FOIL.

What is the new coordinate of Point B (8,7) with scale factor r=2? What is the new coordinate of Point C (12,9) with scale factor r=2? What is the new coordinate of Point D (3,10) with scale factor r=2?
Answer:
[tex]B' = (16,14)[/tex]
[tex]C' = (24,18)[/tex]
[tex]D' =(6,20)[/tex]
Step-by-step explanation:
Given
[tex]B = (8,7)[/tex]
[tex]C = (12,9)[/tex]
[tex]D = (3,10)[/tex]
[tex]r = 2[/tex] --- the scale factor
Required
The new coordinate of each point
To do this, we will interpret dilation as stretching.
So, the new point is calculated as:
[tex]New = Old * Scale\ factor[/tex]
[tex]New = Old * r[/tex]
So, we have:
[tex]B = (8,7)[/tex]
[tex]B' = (8,7) * 2[/tex]
[tex]B' = (16,14)[/tex]
[tex]C = (12,9)[/tex]
[tex]C' = (12,9) * 2[/tex]
[tex]C' = (24,18)[/tex]
[tex]D = (3,10)[/tex]
[tex]D' =(3,10) * 2[/tex]
[tex]D' =(6,20)[/tex]
Hence, the new points are:
[tex]B' = (16,14)[/tex]
[tex]C' = (24,18)[/tex]
[tex]D' =(6,20)[/tex]

The area of a square garden is 900m2. Find
its perimeter.
Answer:
120m
Step-by-step explanation:
Each side of square have same length, assume x for one side of square:
x^2=900
x=30
perimeter:30x4=120m
Answer:
120 square meters
Step-by-step explanation:
Since area is base times height and this is a square, we know all sides are the same length. Take the square root of 900 and you will get 30, meaning each side is thirty meters long. 30 x 4 = 120, that’s your perimeter. Hope this helps!

the manager of a bookstore uses the equation s = p - 3.5 to find the price a student pays for books
The sale price 's' of a book is $3.50 less than the original price 'p'. This situation is represented by the given equation s = p - 3.5.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The given equation is s = p - 3.5, where 's' represents the sale price and 'p' represents the original price of a book.
The equation shows that to get the sale price 's', the original price 'p' is reduced by $3.50.
If the sale price 'p' of a book is $3.50 less than the original price 's', then we can rewrite the equation as p = s + 3.5.
This situation is not represented by the given equation.
If the sale price 's' of a book is $3.50 more than the original price 'p', then the equation would be s = p + 3.5.
This situation is also not represented by the given equation.
Hence, the sale price 's' of a book is $3.50 less than the original price 'p'. This situation is represented by the given equation s = p - 3.5.

9. Thirty percent of the metal sphere will be covered in a metal that is tinted red. What is the area of the section of the sphere that is tinted red?
please help :))
Step-by-step explanation:
Given that,
8. The radius of a sphere, r = 115 cm
We need to find the surface area of the metal sphere. The formula for the surface area of a sphere is given by :
[tex]A=4\pi r^2[/tex]
Put all the values,
[tex]A=4\times 3.14 \times (115)^2\\\\=166106\ cm^2[/tex]
9. Thirty percent of the metal sphere will be covered in a metal that is tinted red.
So, the area of the section that is tinted red is :
[tex]A=30\%\ of\ 166106\\\\=\dfrac{30}{100}\times 166106\\\\=49831.8\ cm^2[/tex]
