The diameter of the new ball, to the nearest tenth of a centimeter, is 11.0cm
We have given that,
The surface area of a regulation spherical soccer ball is about 484π
square centimeters. If the diameter of the regulation ball is reduced by 50% to produce a new ball.
We have to determine,
The diameter of the new ball, to the nearest tenth of a centimeter.
What is the surface area of a spherical soccer ball?
The volume of a sphere = 4/3 × πr^3.
Therefore we get,
[tex]\frac{484}{50}= 11.0[/tex]
Therefore we get the diameter of the new ball, to the nearest tenth of a centimeter is 11.0cm.

What type of study would you conduct if you wanted to know how many hours a week on average students at your school spend on homework? Explain your reasoning.
Answer:
In order to get the number of hours spent by the students on homework, a survey would be conducted where information would be collected from the students.
Step-by-step explanation:
In order to acquire the information directly from the users which cannot be measured otherwise, surveys are the best option. These provide an appropriate way of reaching out to large masses at a small-time with little or no prior investment.
Se quiere realizar la adición y multiplicación de los números enteros 43 y -32. En relación con los signos de las operaciones se puede decir que
Answer:
El caso de la adición es trivial.
La adición entre los números A y B es:
A + B
Entonces la adición entre los números 43 y -32 es:
43 + (-32)
No hace falta realizar la suma para darnos cuenta de que el resultado tendra signo positivo, esto se da porque el módulo del número positivo es mayor que el del número negativo.
Así tenemos:
43 + (-32) = 43 - 32 = 11
Para el caso de la multiplicación podemos recordar:
(+)*(+) = (+)
(-)*(+) = (-)
(+)*(-) = (-)
(-)*(-) = (+)
Entonces el producto entre un número positivo y uno negativo (como es nuestro caso con 43 y -32) siempre tendrá un signo negativo.
Entonces podemos concluir que el signo de la multiplicación entre esos dos números va a ser negativo.
También podemos resolver la multiplicación de otra forma para ver esto:
43*(-32)
43*( (-1)*32)
43*(-1)*(32)
(-1)*(43*32)
Que es claramente un número negativo.

Use the Pythagorean Theorem:
a²+b²=c²
15²+b²=17²
225+b²=289
b²=64
b=8
Therefore, the missing side is 8 inches long.

100,000^1/5 x a + 1,000,000^1/2 x a
Answer:
1010a
Step-by-step explanation:
Mathematically, when a number is raised to a fraction, it simply means we are to find the root of that number to the denominator of the given fraction
For example;
100,000^1/5
= 5 x√((100,000) = 10
Likewise;
1,000,000^1/2 = √(1,000,000) = 1000
Thus, we have it that;
10 * a + 1000 * a
= 10a + 1000a = a(1000 + 10) = 1010a

Consider the quadratic function y = 1/5(x - 2)2 + 5.
Which statements are true about the function and its graph? Select two options.
The vertex of the function is (-2,5).
There are no real roots for the function.
The graph of the function opens down.
The graph contains the point (2,5).
The graph intersects the x-axis at one unique point.
Answer:
Step-by-step explanation:
There are no real roots and the graph contains point (2,5). Notice it is in vertex form. So there must be a point at x = 2 and y = 5. However, if it is the vertex and it opens upwards, that means it cannot intersect the x axis. So 2 and 4 are the correct answers I believe.

Which of the equations shows an application of the Zero Property of Multiplication? A. 25+0=25 B. 13(3)= C. 0∙2=0 D. (34−2)−(34+3)=−5
Answer:
0∙2=0
Step-by-step explanation:
Zero Property of multiplication is as follows :
The product of a number and 0 is equal to 0.
In option (c), 0 is multiplied by 2 and as a result, we get 0 as the answer.
It means,
0∙2=0
Hence, option (c) i.e. 0∙2=0 shows the Zero Property of Multiplication.

The value of the given expression into a single power.
Solution:
Given that,
[tex]\dfrac{(-24)^5}{(-24)}[/tex]
It can be rewritten as:
