Is 39,052 divisible by 3?
Answer:
no as the answer would be a decimal
Step-by-step explanation:
an easier way to know is to add up all the digits
3 + 9+0 +5+2= 19 and if that number is a multiple of 3 then it will be divisible by 3
this works for any number that should be divided by 3
example
is 2345 divisible by 3
2+3+4+5 =14 so no it is not divisible by 3
example
is 12345 divisible by 3
1+2+3+4+5 =15 so yes it is divisible by 3

3x - 31 = 20 ( add 31 to both sides )
3x = 51 ( divide both sides by 3 )

What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
Let the integers loss is represented by negative integers whereas profit is represented by positive numbers.
Given, Beginning price = $24.75
Over the next 5 days,
On Monday, gain of $2.50 represented by; + $2.50.
On Tuesday, loss of $3.25 represented by; - $3.25 .
On Wednesday, loss of $0.75 represented by; - $0.75.
On Thursday, gain of $1.25 represented by ;+ $1.25.
On Friday, gain of $4.75 represented by; + $4.75.
The Price of the share of stock at the end of Friday would be;
= (Beginning price)+ ( + $2.50 - $3.25- $0.75+ $1.25+ $4.75)
= $( 24.75 + 2.50 -3.25 -0.75 +1.25 +4.75)
= $29.25

- Find the coordinates of A if B(0,5.5) is the midpoint of AC and C has coordinates
(-3,6).
Given:
Coordinates of point C are (-3,6).
Point B(0,5.5) is the midpoint of AC.
To find:
The coordinates of A.
Solution:
Let the coordinates of point A are (a,b).
Formula for midpoint:
[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]
Using the above formula, the midpoint of A(a,b) and C(-3,6) is
[tex]B=\left(\dfrac{a+(-3)}{2},\dfrac{b+6}{2}\right)[/tex]
[tex](0,5.5)=\left(\dfrac{a-3}{2},\dfrac{b+6}{2}\right)[/tex]
On comparing both sides, we get
[tex]\dfrac{a-3}{2}=0[/tex]
[tex]a-3=0[/tex]
[tex]a=3[/tex]
and,
[tex]\dfrac{b+6}{2}=5.5[/tex]
[tex]b+6=11[/tex]
[tex]b=11-6[/tex]
[tex]b=5[/tex]
Therefore, the coordinates of point A are (3,5).

grabs a marble, what is the probability that he will pick a black marble?
Answer:
0.4
Step-by-step explanation:
The formula to calculate number of black marbles isnumber of favourable items by number of favourable items i.e for black marbles it will become
P(B)=number of black marbles divide by total number of marbles
P(B)=6/15
P(B)=0.4 OR 40%
Therefore the probability that Tommy will pick black marble is 0.4 or 40%
You are baking cookies for your class. There are 23 total students in your class and you have baked 12 cookies.

Please help Thank you
Answer:
12+2x=46 x=17 cookies
Step-by-step explanation:
First you are going to double the number of students because each student is getting 2 cookies. Then you will subtract 12 from 46 and that gets you 34. Then you will divide 2 by 34 to get how many cookies she needs to bake. 17 more cookies. To check your work plug in 17 by the x. so 2 times 17 is 34 plus 12 is 46 so that answer is correct.

The pressure exerted on an object under water increases by 1 atmosphere every 33 feet below the surface of the water. At sea level, the pressure is l atmosphere. Which equation gives the total pressure p, in atmospheres, exerted on an underwater object at a depth of f feet below sea level? A) P 33 B) p 33f C) p 33f+ 1
Answer:
ooooooooooooooooooooooooo
The linear function that gives the total pressure exerted on an underwater object at a depth of f feet below sea level is given by:
p = l + 0.0303f.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.In this problem:
The pressure changes by 1 for each 33 feet of depth, hence m = 1/33 = 0.0303.The initial pressure is of l, hence b = l.Thus, the function is given by:
p = l + 0.0303f

How many times larger is 5 × 10^6 than 5 × 10^2
Answer:
3 times
Step-by-step explanation:
The number 5 x 10⁶ is 10000 times greater than the number 5 x 10².
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the numbers are 5 x 10⁶ and 5 x 10². How many times the number is greater will be calculated by dividing the bigger number by the smaller number.
E = ( 5 x 10⁶) / ( 5 x 10² )
E = 10000
Therefore, the number 5 x 10⁶ is 10000 times greater than the number 5 x 10².
