Find the number of positive divisors of 1470.
Answer:
1, 3, 17, 29, 51, 87, 493, 1479
Step-by-step explanation:
Divisors of number 1479: 1, 3, 17, 29, 51, 87, 493, 1479
Number of divisors: 8
Sum of its divisors: 2160
Answer: plz mark as brainliest
Step-by-step explanation:Here we will define what "the divisors of 1470" means and show you how to find the divisors of 1470.
First, note that in a division problem like x divided by y equals z, x is the dividend, y is the divisor, and z is the quotient as illustrated here:
Dividend / Divisor = Quotient
Divisors of 1470 are all the unique whole number divisors that make the quotient a whole number if you make the dividend 1470:
1470 / Divisor = Quotient
To find all the divisors of 1470, we first divide 1470 by every whole number up to 1470 like so:
1470 / 1 = 1470
1470 / 2 = 735
1470 / 3 = 490
1470 / 4 = 367.5
etc...
Then, we take the divisors from the list above if the quotient was a whole number. This new list is the Divisors of 1470.
The Divisors of 1470 are as follows:
1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 49, 70, 98, 105, 147, 210, 245, 294, 490, 735, and 1470.

how do you calculate the area of this square which has two semicircles in it?
please help
The area of the square is 100 square units because 10×10=100
The radius of a circle is half the length of the square. The radius is 5.
The 2 semi-circles added together actually equals a circle.
The area of a circle is π[tex]r^{2}[/tex].
5=r.
So [tex]5^{2}[/tex] equals 25.
The circle is 25π
So just subtract.
The area of the square with two semi-circles in it is (100 - 25π)

What is the approximate value of tan C?
Please help! Urgent!
Hey there! I'm happy to help!
Tan means tangent. The tangent is the ratio of the opposite side of the angle to the adjacent side of the angle.
If we look across from angle C, we see that the opposite side is 5.
The adjacent side is the one next to the angle, and it can't be the hypotenuse (the diagonal one). Our adjacent side is 13.
So, the tangent of C is 5/13, and we can divide these, giving us about D. 0.38.
Have a wonderful day! :D

Solve the equation
(If possible please show work)
Answer:
[tex]x=-3[/tex]
Step-by-step explanation:
So we have the equation:
[tex]-2(-x-4)+3=-7-4x[/tex]
First, distribute the left side:
[tex]-2(-x)-2(-4)+3=-7-4x\\2x+8+3=-7-4x[/tex]
Add values on the left side:
[tex]2x+11=-7-4x[/tex]
Add 7 to both sides. The right side cancels:
[tex](2x+11)+7=(-7-4x)+7\\2x+18=-4x[/tex]
Subtract 2x from both sides. The left side cancels:
[tex](2x+18)-2x=(-4x)-2x\\18=-6x[/tex]
Divide both sides by -6:
[tex](-6x)/-6=18/-6\\x=-3[/tex]
Therefore, x equals -3.
Answer:
[tex]x = - 3[/tex]
Step-by-step explanation:
[tex] - 2( - x - 4) + 3 = - 7 - 4x[/tex]
[tex]to \: get \: rid \: of \: the \: parenheses \: \\ distribute \: two \: through \: the \: parentheses[/tex]

A bag contains 7 red marbles and 4 blue marbles.
A marble is taken at random from the bag and replaced.
Another marble is taken from the bag.
Work out the probability that the two marbles
taken from the bag are the same colour.
Answer:
calculate the probability that the marbles are the same color, then subtract this probability from 1 to find the probability they are different colors. P(2 of the same) = P(2 green) + P(2 yellow) + P(2 red) = 1/26 + 5/26 + 2/26 = 8/26 = 4/13. P(2 different) = 1 - P(2 of the same) = 1 - 4/13 = 9/13.

How are the properties of segments and angles used to determine their measures
Answer:
See below
Step-by-step explanation:
Use of following postulates and properties of line segments and angles will help in measuring them.
The Segment Addition Postulate
It states that given 2 points A and C, a third point B lies on the line segment AC if and only if the distances between the points satisfy the equation AB + BC = ACThe Angle Addition Postulate
It states that if B is in the interior of AOC , then m∠AOB+m∠BOC=m∠AOC. That is, the measure of the larger angle is the sum of the measures of the two smaller ones.If f(x) = 2x + 7 and g(x)= 3x² -1, what expression represents (f(g(x)) ?
A 6x2 +5
B 6x2 +12
C 3x2 - 2x -8
D 3x2 + 2x + 6
Answer:
A. 6x^2+5
Step-by-step explanation:
The expression that represents the function (f(g(x))) is 6x² + 5, option A is correct.
Given expressions are f(x) = 2x + 7 and g(x) = 3x² - 1
To find (f(g(x))), we substitute g(x) into f(x):
f(g(x)) = 2(g(x)) + 7
Substituting g(x) = 3x² - 1:
f(g(x)) = 2(3x² - 1) + 7
Distributing the 2:
f(g(x)) = 6x² - 2 + 7
Combining like terms:
f(g(x)) = 6x² + 5

X = [tex]\frac{L}{6\pi r }[/tex] - [tex]\frac{5r}{6}[/tex]
Step-by-step explanation:
1. Solve for x, 5 (2x + 3) + 3 (x - 4) = 25 And one more question 2. The perimeter of a rectangle is 40m. The length of the rectangle is 4 m less than 5 times its breadth. Find the length of the rectangle.
Answer:
Step-by-step explanation:
1) 5(2x + 3) + 3(x -4) = 25
Use distributive property
5*2x + 5 *3 + 3*x - 3*4 = 25
10x + 15 + 3x - 12 = 25
Add like terms
10x + 3x +15 - 12 = 25
13x + 3 = 25
Subtract 3 form both sides
13x = 25 - 3
13x = 22
x = 22/13
x = [tex]1\frac{9}{13}[/tex]
2) Breadth = b m
Length = 5b - 4
Perimeter of rectangle = 40 m
2*(length + breadth) = 40 { Plug in the values of breadth & length}
2* (5b - 4 + b) = 40
2 * ( 6b - 4 ) = 40
2*6b - 2 *4 = 40
12b - 8 = 40 { add 8 to both sides}
12b - 8 + 8 = 40 + 8
12b = 48 { divide both sides by 12}
12b/12 = 48/12
b = 4 m
Breadth = 4m
Length = 5*4 - 4 = 20 - 4 = 16 m
Answer:
16cm
Step-by-step explanation:
5(2x+3) + 3 (x-4)= 25
10x+15+3x-12=25
(combine the like terms)
13x+3=25
13x= 22
x= 1 and 9/13
perimeter= 40m
length=5a-4
breadth=a
5a-4+a+5a-4+a= 40
12a-4-4 = 40
12a-8=40
12a= 48 a= 4cm
the breadth is 4cm, the length is 5×a-4= 20-4 =16cm

Your sock drawer has two white socks, four brown socks, and two black socks. You randomly pick a sock and put it on your left foot and then pick another sock and put it on your right foot. You leave the house with a white sock on your left foot and a brown sock on your right foot. Find the probability of this occuring.
Answer:
The probability of this occurring is 1/7
Step-by-step explanation:
Okay, here is a probability question.
From the question, we can identify the following;
Total number of socks = 2 + 4 + 2 = 8 socks
Since we are not given the order in which the socks was worn, we can assume any order.
Let’s say the right leg socks was worn first.
From the question, the socks on the right leg is a brown one.
So now let’s calculate the probability of selecting a brown socks out of the mix
That would be ;
number of brown socks/ total number of socks = 4/8 = 1/2
Now, for the left foot, we are having white sock here.
Kindly recall that since we already have a sock on the right foot, we have 7 socks left to pick from.
Now we need the probability of picking a white sock from the total 7. That would be ; 2/7
So the probability of both action occurring is simply the product of both probabilities and that is ;
1/2 * 2/7 = 1/7

A toy factory sold 120,587 toys in 25 days. If each toy was sold for $58, about how much money did the factory earn in 25 days? Estimate the answer by rounding off the number of toys to the nearest thousand.
This value is a little over 7 million dollars
======================================================
Explanation:
120,587 rounds to 121,000 when rounding to the nearest thousand.
The instructions don't mention rounding 58, so we'll leave it as that
Multiply the values to get
58*121,000 = 7,018,000
which is the estimate of how much money was earned.
-----------
The actual amount of money earned is
58*120,587 = 6,994,046
which isn't too far off of our estimate.
-----------
Note: the value of 25 days is never used. You could have any other number of days you want, and the answer is still the same. This value is probably either filler or some kind of distraction.

Answer:
[tex]\Large \boxed{ \mathrm{377 \ pounds \ per \ square \ inch} }[/tex]
Step-by-step explanation:
The initial pressure was 435 pounds per square inch.
From 12:00 PM to 1:00 PM, the initial pressure increases by 58 pounds per square inch and then decreases 116 pounds per square inch.
⇒ 435 + 58 - 116
⇒ 377
Answer:
[tex]\huge\boxed{377 \ pounds / in.^2}[/tex]
Step-by-step explanation:
The initial pressure was 435 pounds / in.²
After that it increases by 58 pounds / in.²
So, it became
=> 435 + 58
=> 493 pounds / in.²
Then, it decreases by 116 pounds/square inch
=> 493 - 116
=> 377 pound / in.²
This is the final pressure.
