Answer:
3.1 * 10^10
Step-by-step explanation:
we know 1 billion is 1,000,000,000
In scientific notation
1,000,000,000=1 * 10^9
To find the value of 31 Billion
Multiply the value of one billion for 31
so
31 * 1 * 10^9 = 31 * 10^9
= 3.1 * 10^10

hope it helps
Answer:
176.
Step-by-step explanation:
112 = 2*2*2*2*7
For a cube number there must be 3 or a multiple of 3 of each factor.
So we multiply by 2*2 and 7 * 7 to give 2^6 * 7^3 which is 21952.
The answer is 4*49
= 176.
Checking that 21952 is a cube:
- the cube root is 28,

3x+2y=46 x+y=17 how u solve
Answer: (12, 5)
Step-by-step explanation:
3x + 2y = 46 x + y = 17
Subtract y from both sides of the equation.
x = 17 − y 3x + 2y = 46
Replace all occurrences of x with 17 − y in each equation.
51 − y = 46
x = 17 − y
Solve for y in the first equation.
Move all terms not containing y to the right side of the equation.
Subtract 51 from both sides of the equation.
−y = 46 − 51
x = 17 − y
Subtract 51 from 46.
−y = −5
x = 17 − y
Multiply each term in −y = −5 by −1
Multiply each term in −y = −5 by −1. (−y) ⋅ −1 = (−5) ⋅ −1
x = 17 − y
Multiply (−y) ⋅ −1.
y = (−5) ⋅ −1
x = 17 − y
Multiply −5 by −1.
y = 5
x = 17 − y
Replace all occurrences of y with 5 in each equation.
Replace all occurrences of y in x = 17 − y with 5. x = 17 − (5)
y = 5
Simplify 17 − (5).
Multiply −1 by 5.
x = 17 − 5
y = 5
Subtract 5 from 17.
x = 12
y = 5
The solution to the system is the complete set of ordered pairs that are valid solutions.

What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the first number be A
Now , the value of A is = 16 cm
Let the second number be = B
The value of B is = 20 cm
The ratio of A and B is calculated as C
where C = A / B
A goes to the numerator of the fraction and B to the denominator
Substituting the values in the equation , we get
C = A/B
C = 16/20
On simplifying the equation , we get
C = 4/5
Therefore , the value of C is 4 : 5
Hence , the value of equation is 4 : 5

The rectangle to the right has width 6x5 feet and length 9x8 feet. Find its area as
an expression of x.
Answer:
54x¹³Step-by-step explanation:
area = L x W
where L = 9x⁸
W = 6x⁵
plugin values into the formula:
Area = 9x⁸ * 6x⁵
= 54x¹³
The area of the rectangle as an expression of x is [tex]2160x^3[/tex] square feet.
To find the area of the rectangle, we can use the formula for the area of a rectangle, which is:
Area = length × width
Given that the width is 6x5 feet and the length is 9x8 feet, the area of the rectangle is:
Area = (9x8) × (6x5)
To simplify the expression, multiply the coefficients and combine the variables:
[tex]Area = 54x^2 * 40x[/tex]
Now, multiply the coefficients:
[tex]Area = 2160x^3[/tex]
So, the area of the rectangle as an expression of x is [tex]2160x^3[/tex] square feet.

Maria can paint an area of 100 square feet in one-third of an hour. At this rate, how
many square feet can she paint in one minute?
Answer:
A. 5 square feet per minute
Step-by-step explanation:
Answer:
The answer is 5 square feet per minute.
Step-by-step explanation:
Since 1/3 of an hour is 20 minutes, it will look like 100 square feet/20 min.
To make 20 minutes into one minute, we have to divide it by 20.
Because we did it to the denominator, we also have to do the same thing to the numerator.
Divided 100 by 20, which gives you 5.

The perimeter of a triangular shaped garden is 24 feet. The third side is one more than four times the first side. The second side is three more than the first side
What is the length of the longest side of the garden?
Answer:
14 1/3 feet
Step-by-step explanation:
let 's' = shortest side
let '4s + 1' = longest side
let '3 + s' = middle side
s + 4s + 1 + 3 + s = 24
6s + 4 = 24
6s = 20
s = 20/6 or 3 1/3

Solve the system of linear equations by elimination. 10x-9y=46 and -2x+3y=10
Answer:
y=16 and x=19
Step-by-step explanation:
Let's solve your system by elimination.
−2x+3y=10;10x−9y=46
Multiply the first equation by 5,and multiply the second equation by 1.
5(−2x+3y=10)
1(10x−9y=46)
Becomes:
−10x+15y=50
10x−9y=46
Add these equations to eliminate x:
6y=96
Then solve6y=96for y:
6y=96
6y
6
=
96
6
(Divide both sides by 6)
y=16
Write down an original equation:
−2x+3y=10
Substitute16foryin−2x+3y=10:
−2x+(3)(16)=10
−2x+48=10(Simplify both sides of the equation)
−2x+48+−48=10+−48(Add -48 to both sides)
−2x=−38
−2x
−2
=
−38
−2
(Divide both sides by -2)
x=19
Answer:
x=19 and y=16
The value of x and y on solving a system of linear equations 10x - 9y = 46 and -2x + 3y = 10 by elimination are 19 and 16 respectively.
What is equation?A formula known as an equation uses the equals sign to denote the equality of two expressions.
Given equations:
10x - 9y = 46 (1)
-2x + 3y = 10 (2)
Multiply equation 2 by 3
3 (-2x + 3y) = 10 × 3
-6x + 9y = 30 (3)
Add equation 3 and equation 1
10x - 9y + (-6x) + 9y = 46 + 30
4x = 76
x = 76 / 4 = 19
Put x = 19 in equation 2
-2 × 19 + 3y = 10
3y = 10 + 38
y = 48 / 3
y = 16
Therefore, the value of x and y on solving a system of linear equations 10x - 9y = 46 and -2x + 3y = 10 by elimination are 19 and 16 respectively.

Answer:
C
Step-by-step explanation:
Firstly, we will identify the angle that has the given cosine value
From what we can see, the arc cos of this value is 45 degrees
but, as we can see, the value is negative
On the quadrants, the value of cosine is negative on the 2nd and 3rd quadrant
2nd quadrant ranges from 90 - 180
That is pi/2 to pi
3rd ranges from 180 to 270
That is pi to 3pi/2
Kindly recall, we are considering angles from -360 to 360
So what this mean is that we will consider angles that are negative of what we have as positive angles on the first and fourth quadrant on which cosine is positive
Thus, we have the following;
5pi/4 is same as 225 degrees
This is on the 3rd quadrant, and cosine is negative there
7pi/4 is same as 315 and this is on the fourth quadrant
This is expected to be negative because normally, cosine is positive on that axis and what we have should be negative
3pi/4 is same as 135
This is on the second quadrant and normally, cosine is negative here so we do not need to negate the angle measure
pi/4 is on the first quadrant and cosine is positive here;
Since the value we have here is positive, we have to negate the angle measure
So the correct angles are;
negative pi/4
positive 3pi/4
positive 5pi/4
negative 7pi/4
