Step-by-step explanation:
El curso tiene 473 alumnos. Nos dicen que respecto al curso anterior se ha producido un aumento de inscripciones del 10 %. Entonces, siendo x la cantidad de alumnos que había en el curso anterior, se puede plantear la ecuación:
x + 0.1*x= 473
Resolviendo se obtiene:
1.1*x=473
x= 473 ÷1.1
x= 430

The radius of a basketball is 10 inches, and the radius of a soccer ball is 9 inches. How much greater is the volume of the basketball than the soccer ball? Round the nearest tenth.
Answers
Answer:
The basketball volume is 1135.2 in³ greater than the soccer ball volume.
Step-by-step explanation:
Basketball volume is V = (4/3)πr³, or V = (4/3)(3.14)(10 in)³ = 4188.79 in³
Soccer ball volume is V = (4/3)πr³, or V = (4/3)(3.14)(9 in)³ = 3053.63 in³
Subtract the smaller from the larger to determine how much greater the large ball volume is:
4188.79 in³ - 3055.63 in³ = 1135.2 in³

1135.2

A pack of 5 of board games costs $75.
If there is a direct proportion between the price (y) and number of board games (2), which equation represents the
situation?
A
y = 2
y = 15.2
y = 52
y = 75.00
Answers
Answer:
C. y=5x
Step-by-step explanation:
I'm pretty sure that it's y=5x, because it says that y represents the price, and that 2 represents that amount of board games. The price is $75, and the number of board games is 5. So the answer should be y=5x.

oWhat can I say execpt your welcome
The mean is greater than the median.
Option (B) is correct.
To find the statements is true.
What is statistics?A branch of mathematics dealing with the collection, analysis, interpretation, and presentation of masses of numerical data.
Half the students scored 55.
The next highest score is 60. So the median is (55+60) / 2 = 57.5.
A few students scored 72, so the mean is slightly greater than the mean of 55 and 60.
Therefore, the mean is greater than the median.

Dennis stood on a 9 foot ladder to measure the sunflower. How much taller is the tallest sunflower than the ladder?
Answers
Answer:
See Explanation
Step-by-step explanation:
Given
[tex]Ladder = 9ft[/tex]
[tex]Tallest\ Sunflower = x[/tex]
Required
How much taller is the tallest
To get this, we simply calculate the difference between the height of the tallest sunflower and the ladder.
i.e.
[tex]Difference = Tallest\ Sunflower - Ladder[/tex]
[tex]Difference = x - 9[/tex]
-----------------------------------------------------------------------------------------------------
If for instance, the tallest is 13ft, then it is 4ft taller.
Because:
[tex]Difference = 13ft - 9ft[/tex]
[tex]Difference = 4ft[/tex]

Answers
Answer:
A) 180 square feet.
Step-by-step explanation:
The two rectangles are congruent, therefore having the same area.
The area of a rectangle, or any quadrilateral for that matter, is Length x Width.
12 * 4 = 48
There are two, so multiply this number by 2 and you get 96.
The formula for a trapezoid's area is height * 1/2 * (base 1 + base 2)
The height given is 6 feet. The 1st base is 10 feet, and the longer base is 10 + 4 + 4, this equals 18
The formula is now
[tex]6 * \frac{1}{2} (18 + 10)\\6 * \frac{1}{2} (28)\\6* 14\\=84[/tex]
Now in total, 84 + 96 = 180.

A) 6.3% decrease
B) 5% increase
C) 6% decrease
D) 6.3% increase
Answers
Answer:
the answer is d.
Step-by-step explanation:
first, you want to use the formula,
new value - original value
____________________
original value * 100
you see that 84 is the new value and 79 would be the original value. substitute the numbers in. this is a increase since you will get a positive value.
84 - 79
______
79 * 100
now we solve it.

__
79 * 100
you can either solve the fraction first then multiply that by 100 or multiply the numerator by 100 first then divide that by 79, each way works.
500
____
79 = approximately 6.3% increase (this is not a exact value, just rounded)

79 = approximately 0.063 (this is not a exact value, just rounded)
