What is the probability of rolling a 20-sided number cube to a number that is prime or a multiple of 3?
Answer:
Probability of rolling a prime or multiple of 3 = 13/20
Probability of rolling a prime = 2/5
Probability of rolling a multiple of 3 = 3/10
Step-by-step explanation:
let's list primes and multiples of 3 from 1 to 20
Primes:
2 3 5 7 11 13 17 19
Multiples of 3:
3 6 9 12 15 18
Primes OR multiples of 3
2 3 5 6 7 9 11 12 13 15 17 18 19
There's 13 of them, so the probability of rolling a prime or multiple of 3 is 13/20
Probability of rolling a multiple of 3 is 6/20 = 3/10
Probability of rolling a prime is 8/20 = 2/5
Answer:
0.6 or [tex]\frac{12}{20}[/tex] or [tex]\frac{3}{5}[/tex]
Step-by-step explanation:
Here are the multiples of 3 (that are 20 or below) :
369121518Here are the prime numbers (that are 20 or below):
235711131719Some numbers are repeated in the two lists.
Here are all the numbers:
23567911121315181912 numbers are prime or a multiple of 3.
As a fraction it will be [tex]\frac{12}{20}[/tex], or simplified to [tex]\frac{3}{5}[/tex]
As a decimal it will be 0.6

What is 562,148,900 in expanded form
Answer:
562,148,900 =
500,000,000
+ 60,000,000
+ 2,000,000
+ 100,000
+ 40,000
+ 8,000
+ 900
+ 0
+ 0
Answer:
Hello!
First we need to understand what expanded form is!
Expanded form is a way of writing a number to see the value of each digit. An example is:
111
100 + 10 + 1 = 111
So we must find the value of 562,148,900, in expanded form.
First we would find the first digit, and separate it from the other digits.
5
Then, we would count the digits behind that, and add it to the right of the five, in the form of zeroes.
500,000,000
We would continue this process for each digit, and then we would put them in addition form.
Your final answer would be,
500,000,000
60,000,000 +
2,000,000 +
100,000 +
40,000 +
8,000 +
900 +
0 +
0 +

In which number is the digit 2 one hundred times larger than it is in the number 524
Answer: 2,504?
Step-by-step explanation: baccically times the 2 only by 100, or at least that’s what I am seeing. LOL
Any number which has digit 2 at its thousandth place will have the digit 2 one hundred times larger than it is in the number 524
What is place value?Place value is the value of each digit in a number.
For example, the 5 in 350 represents 5 tens, or 50; however, the 5 in 5,006 represents 5 thousands, or 5,000.
It is important that while a digit can be the same, its value depends on where it is in the number.
Given that, we need to determine that which number is the digit 2 one hundred times larger than it is in the number 524,
So, if we consider a number having 2 at its thousandths place,
For example : 32000, the place value of 2 is 2000,
In the number 524, the place value of 2 is 20,
Now, 2000/20 = 100
So, here we see that, the digit 2 in 32000 is 100 times larger than the digit 2 in 524
Hence, any number which has digit 2 at its thousandth place will have the digit 2 one hundred times larger than it is in the number 524

En una tienda de ropa vas a comprarte una pantalones que están de 150 a 90 euros y una camiseta de 40 a 24 ¿ tienen el mismo porcentaje de rebaja ?
Respuesta:
Sí, tienen el mismo descuento del 40%
Explicación paso a paso:
Dado :
PANTALÓN :
Precio inicial = 150
Precio con descuento = 90
Porcentaje de descuento en el precio:
(150 - 90) / 150 * 100%
60/150 * 100%
0,4 * 100
= 40%
CAMISA:
Precio inicial = 40
Precio con descuento = 24
Porcentaje de descuento en el precio:
(40-24) / 150 * 100%

Susie begins a new program with 600 m on the first day each day she will increase her walk by 200 m how many kilometres will she walk on day 18 of her program
Answer: Susie walked 4000 kilometers on day 18 of her program
Step-by-step explanation:
The question explains an arithmetic progression of Susie's walk program
Now the nth term of an AP is given as
an = a1 + (n - 1 ) d
a1 =First term = 600 m
common difference , d =200
The 18th day of her program will be
a18 = 600+ (18 - 1 ) 200
a18 = 600+ 17 x200
a18 = 600+3,400
a18 = 4000
How many square feet of paint will be needed to cover the shed, not including the roof?
4 ft
6 it
41
6 ft
8017
Ob
44
6011?
Od
92
Answer:
80 ft^2 of paint would be needed
Step-by-step explanation:
Since we do not consider the roof, all we need do is to calculate the area of the shape without the roof side
So without the roof, we have 4 rectangles
we have 4 ft by 4 ft on both sides
Then 6 ft by 4 ft on the other two sides
mathematically, the area of a rectangle is the product of its sides
so, we have the total area as;
2(6 * 4) + 2(4 * 4)
= 2(24) + 2(16)
= 48 + 32
= 80 ft^2

The temperature in an oven changes from 350 degrees to 362 degree. What is the percent increase in temperature, to the nearest tenth of a percent?
Answer:
3.4%
Step-by-step explanation:
Find the percent increase by dividing the difference in the temperatures by the original temperature, then multiplying it by 100:
((362 - 350) / 350) x 100
(12 / 350) x 100
= approximately 3.4
So, the percent increase in temperature was approximately 3.4%
