The scientific notation of 78,400,000 will be 7.84 × 10⁷.
What is the law of indices?Index (indices) in Maths is the power or exponent which is raised to a number or a variable.
For example 5³ = 5²5 here we break 5³ into 5² and 5 so it is called the law of indices.
An algebraic expression is a quantity made up of symbols and processes + - / and multiplication Expressions utilizing indices are made simpler using the laws of indices.
Scientific notation of any number is given in form of a.bcde...× 10^something
Given the number,
78,400,000
Multiply and divide by 10⁷
⇒ 78,400,000 × 10⁷/10⁷
⇒ 7.84 × 10⁷.
Hence "The scientific notation of 78,400,000 will be 7.84 × 10⁷".

Mr.russo exchanged 200 euros for 270 dollars how many dollar he get foe 300 euros
Answer:
$405
Step-by-step explanation:
This is a proportion problem!
Build fractions that have euros on top and dollars on the bottom (or the other way around, you decide, but make it the same in both fractions).
Let's do euros over dollars.
Setup:
[tex]\frac{200}{270}=\frac{300}{d}[/tex]
"Cross multiply."
[tex]200d=300\times 270\\\\200d=81000\\\\d=\frac{81000}{200}=405[/tex]

Answer:
a) I donot agree with him because as we see the sequence nicely we will find an interval of 8 between any two terms and 32 and 33 don't match them
Step-by-step explanation:
b) and c) Solution:
Given,
First term (a) = 4
Common difference (d) = 12-4 = 8
Now,
Since, they are in A.P.
nth term = a + (n-1)d
= 4 + 8(n-1)
= 4 + 8n-8
= 8n-4
Again,
1st method for c)
100th term = a + 99d = 4 + 99*8 = 4 + 792 = 796
200th term = a + 199d = 4 + 199*8 = 4 + 1592 = 1596
2nd method for c)
100th term = 8*100 - 4 = 800 - 4 = 796
200th term = 8*200 - 4 = 1600 - 4 = 1596

Answer:
Option A, 4X + 40 expression is equivalent to the expression for the perimeter of the larger garden
Step-by-step explanation:
The complete question is
A garden is 15 feet long by 5 feet wide. The length and width of the garden will each be increased by the same number of feet. This expression represents the perimeter of the larger garden: (x+15)+(x+5)+(x+15)+(x+5). Which expression is equivalent to the expression for the perimeter of the larger garden? Select all that apply.
4x+40 2(2x+20) 2(x+15)(x+5) 4(x+15)(x+5) 2(x+15)+2(x+5)Solution
The expression for the perimeter of the larger garden: [tex](x+15)+(x+5)+(x+15)+(x+5)[/tex]
If the given expression is expanded and solved, we get the following
[tex](x+15)+(x+5)+(x+15)+(x+5)\\X+X+X+X + 15+15+5+5\\2X+2X+30+10\\4X +40[/tex]
Hence, option A is correct

Answer:
124°
Step-by-step explanation:
measure of arc DC = 44 because the measure of central angle equals the measure of its arc.

Ryan earns $5 for each small dog he walks and $8 for each large dog he walks. Today he walked 8 dogs and made a total of $49. How
many small dogs did Ryan walk?
Answer:
5
Step-by-step explanation:
There are no multiples of 5 or 8 that would end with 9. But if he walks 3 large dogs he gets 24 dollars. if he walks 5 small dogs thats an additional 25 dollars. so he would make 49 dollars.

Answer:
$45
y = 45x + 15
Step-by-step explanation:
Given :
Days Total Cost
(d) (C)
2. $105
4 $195
6 $285
10 $465
The daily rate is the slope :
Slope = Rise / Run
Slope = (y2 - y1) / (x2 - x1)
Slope = (465 - 105) / (10 - 2)
Slope = 360 / 8
Slope = 45
Daily rate = $45
Using the slope intercept relation :
y = mx + c
m = slope, c = intercept
105 = 45x + c
105 = 45(2) + c
105 = 90 + c
105 - 90 = c
15 = c
Pricing plan :
y = 45x + 15
Answer is 45 because if you divide 90/2 it equal 45

Answer:
A = 5 units²
Step-by-step explanation:
The area (A) of a rhombus is calculated as
A = [tex]\frac{1}{2}[/tex] × d₁ × d₂
d₁ = x + 4 = 1 + 4 = 5
d₂ = 2y - 4 = 2(3) - 4 = 6 - 4 = 2 , then
A = [tex]\frac{1}{2}[/tex] × 5 × 2 = 5 units²
Answer:
A= 5m
Step-by-step explanation:
The equation to find the area of a rhombus, when knowing the diagonals, is:
1/2×d1×d2To solve this, we have to find first d1 and d2, which are marked in a parenthesis:
d1= (x+4)m, where x=1d1= 5md1= 5m. Now, let's find d2:
d2= (2y-4)m, and y=3d2= (6-4)md2= 2mKnowing the values of both diameters, we can solve the equation for the area:
A= 1/2×d1×d2A= 1/2×5m×2mA= 1/2×10mA= 5mThe area of the rhombus is 5 meters.

John’s Rectangle is _____ units long.
John’s Rectangle is _____ units wide.
The area of John’s rectangle is ____ units^2.
Answer:
John's rectangle is 4 units long
John's rectangle is [tex]3\frac{1}{2}[/tex] units long
The area of John's rectangle is 14 units^2
Step-by-step explanation:
A rectangle has four sides that comprise of two pairs of equal length sides
The side which is the longest side of a rectangle is known as the length, L, of the rectangle
The side which is the shortest side of a rectangle is known as the width, W of the rectangle
Based on the given measurement, the length of the given rectangle which is the length of longest side of the rectangle, which is the 4 units length side
Therefore;
∴ John's Rectangle is L = 4 units long
the width of the given rectangle which is the length of shortest side of the rectangle, which is the side with lengths 3 units and 1/2 units length side
∴ The length of the shortest side of the rectangle, W = 3 units + 1/2 units = 3 1/2 units
∴ John's rectangle is W = [tex]3\frac{1}{2}[/tex] units wide
The area of John's rectangle, A = L × W
∴ The area of John's rectangle, A = 4 units × [tex]3\frac{1}{2}[/tex] units = 14 units².
